Atmospheric sampling glow discharge provides a simple, rugged, and efficient means for anion formation white the quadrupole ion trap provides for efficient tandem mass spectrometry. Mass-selective ion accumulation and non-specific ion activation methods can be used to overcome deleterious effects arising from ion/ion interactions, Such interactions constitute the major potential technical barrier to the use of the ion trap for real-time monitoring of targeted compounds in uncontrolled and highly variable matrices, Tailored waveforms can be used to effect both mass-selective ion accumulation and ion activation, Concatenated tailored waveforms allow for both functions in a single experiment, thereby providing the capability for monitoring several targeted species simultaneously.

This represents a 5.8% photon-to-nitro group conversion efficiency. A laser intensity threshold is observed, above which thermal decomposition occurs.

Accurate mass measurements and selective dissociation experiments were used to examine the fragmentation pathways of small oligonucleotides in detail. Sustained off-resonance irradiation (SORI) was found to be superior to conventional on-resonance collisionally activated dissociation (CAD) for the efficient dissociation and detection of fragment ions for oligonucleotides. These experiments indicated that oligonucleotide fragmentation is a complex process and results not only from simple elimination of nucleic bases and cleavages of phosphate ester bonds, but also by rearrangement processes in which a terminal phosphate moiety can be transferred to an internal phosphate group.

The first-order model in its present form, along with refinements resulting from further detailed comparison with experimental data, should therefore be a useful tool in expanding our understanding of polyatomic ion energetics in the Paul trap.

A solid-phase microextraction fiber was demonstrated to be an effective sampling medium for several organometallic compounds in both water and a water/soil slurry, Quantification of inorganic mercury species was facilitated by using an alkylating reagent (methylpentacyanocobaltate (III)) to produce an organomercurial that could be analyzed by GC/MS, Although the reaction proceeded as anticipated, several additional observations were made that may be exploited in future studies.

Small changes in surface potential from the nominal sample bias of 500 V were deduced from shifts in the TOF spectra by use of a large extraction distance and modified ion mirror design. Experimental peak shapes and shifts were duplicated by modeling the ion flight times throughout the mass spectrometer to confirm the results. By monitoring peak positions we were able to adjust charge compensation parameters, thereby keeping the surface potential at the desired value. This technique offers the opportunity to investigate the fundamentals of sample charging, or can be used to evaluate the effectiveness of charge compensation during SIMS analysis of insulators.

Protein and peptide solutions having high salt concentrations were infused into a microdialysis tube which was directly interfaced with a micro-ESI source. The microdialysis tube was surrounded by a counter-current flow of a buffer solution consisting of 10 mM ammonium acetate. Desalting was completed in one to four minutes for samples containing up to 250 mM NaCl, which would otherwise have required several hours using alternative off-line desalting schemes. The on-line desalting method also increased the signal-to-noise ratio by a factor of more than 40 compared with that obtained without desalting. Detection of subpicomole samples of apomyoglobin having a high salt concentration was also achieved. Initial results for apomyoglobin, albumin and angiotensin I indicate broad applicability of the method. C1 PACIFIC NW NATL LAB,ENVIRONM MOL SCI LAB,RICHLAND,WA 99352.

Using micro-sampling methods and ion accumulation techniques based on quadrupolar excitation, we demonstrate that adequate sensitivity exists to characterize the hemoglobin from a single human erythrocyte (approximate to 450 amol). In these studies mass spectra with average mass resolution in excess of 45 000 (FWHM) were obtained for both the alpha- and beta chain of hemoglobin following in-column lysing of a single erythrocyte.

In this design, the terminus of the CE separation capillary and a short ESI emitter capillary are connected and sheathed by polysulphone micro-dialysis tubing. The electrical connection, to close the CE circuit and simultaneously establish the electrospray voltage, is provided outside the membrane via an electrode in a small liquid reservoir. In contrast to the sheath flow and liquid junction interfaces, the flow rate of liquid to the ESI source consists of the CE eluent and is not increased. The use of a 'micro-spray' type emitter produces a stable electrospray at the very low flow rates typical of CE, providing a highly sensitive, efficient interface. Post-separation acidification of analytes via the dialysis junction is also demonstrated. C1 PACIFIC NW NATL LAB,ENVIRONM MOL SCI LAB,RICHLAND,WA 99352.

As opposed to microchannel-plate ion defectors (MCPs) commonly used in such systems, cryogenic detectors such as SIS detectors offer a near 100% detection efficiency for all ions including single, very massive, slow-moving macromolecules. We describe the operating principle of an SIS detector and its use as an ion detector in our matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometer and compare its response to an MCP detector operated in the same system. To our knowledge, this is the first direct comparison of these detector types in this application. A comparison of count rates and time-of-flight spectra obtained with both detectors for human serum albumin (molecular weight 66 000 Da) indicates a two to three orders of magnitude higher detection efficiency per unit area for the SIS detector at this mass. For higher molecular masses we expect an even higher relative efficiency for cryogenic detectors since MCPs show a rapid decline in detection efficiency as ion mass increases, which is not expected to be the case for cryogenic detectors. Our results imply that time-of-flight techniques could be extended beyond the current upper mass limit if cryogenic detectors are used. Initially, cryogenic detectors will be used for the analysis of large protein molecules. If non-fragmenting ionization techniques can be perfected, cryogenic detectors will also open the possibility of the rapid analysis of large DNA molecules and perhaps intact microorganisms.

Phase separation and an underquenched microstructure result from detrimental alpha-Fe precipitation, and the resulting magnetic domain structure is very coarse. Additionally, there is a dramatic dependence of the magnetic properties on the cooling rate (and therefore the particle size) and the powders can be sensitive to environmental degradation. Alloy compositions designed just for GA (as opposed to melt spinning) are necessary to produce an amorphous structure that can be crystallized to result in a fine structure with magnetic properties which are independent of particle size. The addition of titanium and carbon to the melt has been found to change the solidification process sufficiently to result in an "overquenched" slate in which most of the powder size fractions have an amorphous component. Crystallization with a brief heat treatment produces a structure which has improved magnetic properties, in part due to the ability to use compositions with higher Fe contents without alpha-Fe precipitation. Results from magnetometry, magnetic force microscopy, and x-ray analyses will be used to contrast the microstructure, domain structure, and magnetic properties of this new generation of amorphous powders with their multiphase predecessors.

Existing techniques for the evaluation of texture in permanent magnets often rely upon magnetic remanence measurements. However, such determinations art: strictly applicable only to assemblies of non-interacting particles, which nullifies the use of the Stoner-Wohlfarth criteria in texture determinations of "exchange-spring" magnets. New techniques in the determination of texture of bulk permanent magnets are being developed to overcome these inherent experimental difficulties. Crystallographic alignment studied by transmission synchrotron x-ray diffraction as a function of position within the sample reveals insights into the development of texture with deformation level in thermomechanically-processed magnets. Information concerning texture may also be obtained by a different method based on paramagnetic susceptibility measurements. Such measurements also provide Curie temperature data which is sensitive to chemical changes that may have occurred in the magnetic phase during processing.

Since the temperature lift for the magnetocaloric effect spans about 50 K, one will need to utilize several ferromagnets with different magnetic ordering temperatures in order to reach temperatures below similar to 250 K.

However, how cells receive and integrate external signals leading to gene regulation is far from understood. It is now appreciated that two classes of cooperative signals are implicated: a soluble class including hormones and growth factors and a class of insoluble signals emanating from the extracellular matrix (ECM) directly through contact with the cell surface. Using 3-dimensional culture systems and transgenic mice, we have been able to identify some of the elements of this ECM-signaling pathway responsible for gene regulation in rodent mammary gland differentiation and involution. Our major observations are 1) the requirement for a laminin-rich basement membrane; 2) the existence of a cooperative signaling pathway between basement membrane and the lactogenic hormone prolactin (PRL); 3) the importance of beta 1-integrins and bHLH transcription factor(s) and the presence of DNA response elements (exemplified by BCE-1, located on a milk protein gene, beta-casein); and 4) the induction of mammary epithelial cell programmed cell death following degradation of basement membrane. We hypothesize that this cooperative signaling between ECM and PRL may be achieved through integrin- and laminin-directed restructuring of the cytoskeleton leading to profound changes in nuclear architecture and transcription factor localization. We postulate that the latter changes allow the prolactin signal to activate transcription of the beta-casein gene. To further understand the molecular mechanisms underlying ECM and hormonal cooperative signaling, we are currently investigating ECM regulation of a ''solid-state'' signaling pathway including ECM fiber proteins, plasma membrane receptors, cytoskeleton, nuclear matrix and chromatin. We further postulate that disruption of such a pathway may be implicated in cell disorders including transformation and carcinogenesis.

Thus, in vivo competition studies against Z-(-,-)-[I-125]IQNP would provide a potentially more sensitive and accurate probe for demonstrating the in vivo m2 selectivity of the nonradioactive ligands. In addition, Z-(-,-)[I-123]IQNP would potentially be useful for SPECT imaging of muscarinic receptor loss in neurodegenerative diseases.

The primary performance measure under study is the complementary cumulative distribution function (CCDF) used in assessing compliance with the U.S. Environmental Protection Agency's (EPA's) standard for the geologic disposal of radioactive waste (40 CFR 191, Subpart B). The analysis considers releases to the accessible environment initiated by exploratory drilling for natural resources and models cuttings removal to the surface due to drilling intrusions, brine and gas flow in the vicinity of the repository and through drilling intrusions away from the repository, radionuclide transport by the flow of brine through intruding boreholes, and brine flow and radionuclide transport in permeable formations overlying the repository (i.e., the Culebra Dolomite). The effects of 49 imprecisely known variables are assessed with techniques based on Latin hypercube sampling and regression analysis. In addition, the effects of several alternative conceptual models for radionuclide transport in the Culebra Dolomite are investigated. Important issues identified in the analysis include (1) the importance of characterizing retardations and solubilities for individual elements, (2) the impact of assumptions involving human activities, including the rate and properties of drilling intrusions, and (3) the need to resolve the question of whether a single-porosity or dual-porosity transport model is appropriate for use in the Culebra Dolomite.

This comparison is carried out for low (3.5-13 keV) and high (50-100 keV) x-ray energies. For both these energy regimes, we demonstrate that phase retarding crystal optics are not only a viable alternative to specialized insertion devices but in some cases provide a superior source of circularly polarized x rays.

This paper describes a prototype apparatus which is capable of obtaining images with a spatial resolution of about 1 mm at a depth of 25 mm in steel of normal density with the source and detector both on the same side of the object.

The MCP detector response is characterized using 20 keV protons as the primary radiation. An applied electric field E<-4 V/mm, where a negative value of E corresponds to a nearby object that is biased positive relative to the input surface, results in a high spatial resolution and a quantum detection efficiency that is approximately equal to the open area ratio of the MCP. An electric field -15 V/mm, the spatial resolution increases, and the quantum detection efficiency slightly decreases from its maximum value with increasing E. The characteristics of each of these electric field configurations are analyzed in the context of the yield and transport of secondary electrons created at the web of the MCP detector, and the results can be scaled to other ions and energies according to the secondary electron yield of ions striking the web.

All of the analog electronics in the conventional FLL are replaced and implemented by the DSP except for the low-noise field-effect transistor preamplifier at the front end of the signal recovery components. The DSP performs the signal demodulation by synchronously sampling the recovered signals and applying the appropriate full wave rectification. The signals are then integrated, filtered, and applied to the output. At 4.2 K, the white flux noise of the gradiometer measured in a DSP FLL mode is about 4 mu Phi(0)/root Hz and the noise at 1 Hz is 13 mu Phi(0)/root Hz. The corresponding noise levels in the gradiometer operated by the conventional FLL are 1.8 and 3 mu Phi(0) root Hz. The poorer system performance in the DSP FLL compared to the analog FLL is mainly caused by the ambient field noise and interference signals picked up through the connecting cables. Additional noise is also added to the overall noise floor by the instruments employed in the DSP system in the present prototype setup. Further improvement in the noise characteristics and the dynamic behavior of the DSP SQUID gradiometer is expected when a better configuration of DSP with the associated I/O devices is implemented. Additional improvements of the DSP programs are expected by incorporating higher-order integration, adaptive control, and noise reduction schemes. (C) 1996 American Insitute of Physics.

A movable piston inside the cell adjusts and controls the sample pressure from ambient conditions to 200 atm within +/-0.3 atm. The linewidth at half-height for a C-13 spectrum of carbon dioxide at 15 degrees C and 57.8 atm is found to be 0.5 Hz. The carbon dioxide gas/liquid phase transition is clearly observed by measuring C-13 chemical shifts as the sample pressure approaches equilibrium. The time required for this NMR cell to reach equilibrium with its surroundings is relatively short, usually 15-30 min. The cell body has the same outer dimensions of a standard spinning turbine and fits into a standard 10 mm commercial probehead capable of controlling the sample temperature using the spectrometer's variable temperature unit. The flexibility of the device and the increased speed in making the measurement is demonstrated. Such control of important thermodynamic variables facilitates the NMR study of important biochemical and chemical reactions in gas, liquid, and supercritical fluid environments.

The rapid fabrication is accomplished in one step without the use of molds, dies, forming, pressing, sintering or forging equipment. Moreover, DLF is performed in a high purity inert environment minimizing the contaminants associated with conventional processing such as oxygen and carbon pickup, lubricants, binding agents, cooling or cleaning agents. Applications using rhenium have historically been limited in part by its high melting temperature, workability, and cost. This study demonstrates the ability to fuse rhenium metal powder, using a DLF machine, into free standing rods and describes the associated parameter study. In addition, microstructural comparisons between DLF processed rhenium and commercial rhenium sheet product is performed. These results, combined with existing DLF Technology, demonstrate a new methodology for fabricating complex near-net shapes and components using rhenium.

Steady-state creep rates for W-4Re-0.32HfC were compared with three second-phase strengthened creep models: the Ansell-Weertman, Lagneborg, and Roesler-Arzt models. The results showed that none of the three models predicted the steady-state creep rates of W-4Re-0.32HfC. However, the recovery creep model of Lagneborg qualitatively fit the steady-state creep rates of the alloy. C1 Univ Calif Los Alamos Natl Lab, Weapon Component Technol Grp, Los Alamos, NM 87545 USA.

Iridium has been used as coating for rhenium rocket thrusters and as an oxidation-resistant coating in a number of other applications. The high strength of rhenium at elevated temperature is combined with the oxidation resistance and high-melting point of iridium. The use of the two metals together is advantageous due to the absence of any stable intermetallic compounds. Both rhenium and iridium alloying additions improve the ductility of tungsten. The high solubility of rhenium in iridium is also taken advantage of to produce iridium-based alloys for structural applications. The uses of rhenium in conjunction with iridium are discussed.

To provide high efficiency in the conversion of thermal energy to electrical energy, these reactors must operate at high temperatures (e.g. >1000 K). These reactors are cooled with a liquid alkali metal such as lithium. Rhenium (Re) is a leading candidate structural material for space power reactors because of its high temperature strength and excellent chemical compatibility with both nuclear fuels and lithium. In such a reactor, Re would be subjected to fast neutron irradiation to fluences of more than 1 x 10(26) n/m(2) (E>0.1 MeV) during several years of operation. The current work was performed to provide information on the tensile properties of Re as a function of temperature and to determine the effects of high temperature neutron irradiation on these properties. Ductility of Re is high (similar to 40%) at low temperatures but decreases abruptly to less than 5% at temperatures above similar to 1200 K. The work hardening coefficient is very high at room temperature and decreases slowly with increased test temperature. Fast neutron irradiation at nominal temperatures of 1300, 1400, and 1600 K to fluences of 8 x 10(25) and 4 x 10(26) n/m(2) resulted in increases in strength and decreases in ductility for tests at room temperature, at the irradiation temperature, and at fifty degrees above the irradiation temperature. These effects decreased with increased irradiation temperature and increased with increased fluence. Also, irradiation lowered the temperature of the abrupt decrease in ductility by more than 200 degrees. C1 Oak Ridge Natl Lab, Oak Ridge, TN 37831 USA.

In the bounded torsional flow, where its radial outer boundary is assumed frictionless, an exact closeform solution is given. With the exception of torsional flows, we find that a limit point for all the steady-state solutions can exist for certain range in the parameter values. In all cases, disturbances can persist for a long time, O (H-2/a(2)), where H is a dimension of the flow field, and a is the particles' radius. C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545.

The limiting factor in the usefulness of plasma cleaning techniques has been the rate at which organic materials are removed. Recent research in the field of plasma chemistry has provided some understanding of plasma processes. By controlling plasma conditions and gas mixtures, ultra-fast plasma cleaning and etching is possible. With enhanced organic removal rates, plasma processes become more desirable as an environmentally sound alternative to traditional solvent or acid dominated process, not only as a cleaning tool, but also as a patterning and machining tool. In this paper, innovations in plasma processes are discussed including enhanced plasma etch rates via plasma environment control and aggressive gas mixtures. Applications that have not been possible with the limited usefulness of past plasma processes are now approaching the realm of possibility. Some of these possible applications will be discussed along with their impact to environmentally conscious manufacturing. RP Ward, PP (reprint author), SANDIA NATL LABS,ALBUQUERQUE,NM 87185, USA.

The development and implementation of 3D System's QuickCast(TM) resin and software for building investment casting patterns have proven to be major steps toward fabricating highly accurate patterns with very good surface finishes. As participants in the Beta est program for QuickCast(TM) resin and software, we experienced a steep learning curve and were able to build accurate parts in a short period of time. It is now possible using this technology to produce highly accurate prototype parts as well as acceptable first article and small lot size production parts. We use the Selective Laser Sintering (SLS) process to fabricate prototype wax patterns for investment casting. DTM Corporation recently introduced the use of their polycarbonate material for fabricating investment casting patterns. The polycarbonate material is processed significantly faster with improved strength, dimensional stability, and without a support structure during the build process. Sandia is currently changing from investment casting wax to polycarbonate for the fabrication of investment casting patterns using the SLS process. This report will focus on our successes with these new materials from the standpoints of application, accuracy, surface finish, and post processing. Also presented will be examples of parts manufactured by these processes. RP Atwood, CL (reprint author), SANDIA NATL LABS,ALBUQUERQUE,NM 87185, USA.

In the field of metallurgy, for example, the interfacial free energy is a crucial factor in the theory of the nucleation, growth, and morphology of precipitates. So far the complexity associated with the inherent disorder at an interface has eluded the ab-initio computation of its free energy and other thermodynamic properties. Here, we show that a particular type of interface can be modeled from first-principles with remarkable accuracy by combining the statistical thermodynamics of the Ising Hamiltonian with the zero-temperature energetics from ab-initio local-density-functional electronic structure calculations.

This process has been established on a commercial scale and is under consideration for treatment of calcium fluoride residues from uranium processing. Magnesium fluoride slags are also available as a product of uranium processing. The technique of using sulfuric acid for the production of hydrogen fluoride from magnesium fluoride is also under consideration as a residue processing scheme. In the current study, thermodynamic modeling was used to investigate these chemical processing systems, the results presented herein reveal information relevant to the selection of processing temperatures and conditions. Details include predicted effects in system composition based on operating temperatures for both the calcium fluoride and the magnesium fluoride systems.

The fuel is dissolved in molten chloride salt. Non-transuranic fission products in the molten salt are ion-exchanged into zeolite A, which is subsequently mixed with glass and consolidated. Zeolite was found to be effective in removing fission product cations from the molten salt. Breakthrough of cesium and the all;aline earths occurred more rapidly than was observed for the rare earths. The effluent composition as a function of time is presented, as well as results for the distribution of fission products along the length of the column. Effects of temperature and salt flow rate are also discussed. C1 Argonne Natl Lab, Div Chem Technol, Argonne, IL 60439 USA.

This metal waste form consists of the fuel cladding (stainless steel or Zircaloy), noble metal fission products (e.g., Ru, Pd, Mo and Tc), and other metallic wastes. The main constituents of the metal waste stream are the cladding hulls (85 to 90 wt%); using the hulls as the dominant alloying component minimizes the overall waste volume as compared to vitrification or metal encapsulation. Two nominal compositions for the waste form are being developed: (1) stainless steel-15 wt% zirconium for stainless steel-clad fuels and (2) zirconium-8 wt% stainless steel for Zircaloy-clad fuels. The noble metal fission products are the primary source of radiation in the metal waste form. However, inclusion of actinides in the metal waste form is being investigated as an option for interim or ultimate storage. Simulated waste form alloys were prepared and analyzed to determine the baseline alloy microstructures and the microstructural distribution of noble metals and actinides, Corrosion tests of the metal waste form alloys indicate that they are highly resistant to corrosion.

This interval was chosen as it straddles the well-documented Late Ordovician glaciation and can be defined by graptolite zones. The anomaly is calculated from neutron activation analysis of low-carbonate, phosphate-free, fossil-free field-identified shales of the graptolite facies by comparison of the normalized cerium content with the linearized trend of the normalized composition of other rare earth elements in order of atomic number. For sections originally deposited in the main pycnocline below the surface mixed layer, values of the anomaly for a given sample would indicate its position on the redox curves developed for the early Paleozoic by Wilde (1987). Changes in the anomaly that are positive with time would indicate a lowering of sea level as the apparent depth on the redox curve would reflect more oxic conditions. Relative changes negative with time would indicate a rise in sea level as the apparent depth reflects more anoxic conditions. Depending on the vertical sample spacing and the time interval sampled, resolution of the order of 1 m.y. might be achieved. Thus the Vail et al. (1977) curves of the 3rd order (1 to 10 m.y.) or of finer scale could be obtained by this technique with the proper choice of section. Accordingly, for the early through middle Paleozoic when the main pycnocline was anoxic, this geochemical technique could be used to develop eustatic sea-level curves and additionally offer an independent calibration for seismic stratigraphy as well as an indicator of glacial-interglacial climatic sequences or eustatic changes due to fluctuations in global ridge crest volumes.

While stacking faults and dislocation loops associated with precipitates are typically observed in bulk GaN, dislocations are the major defect found in epitaxial GaN layers. Formation of stacking faults is equivalent to a wurtzite-zincblede structural transformation within a few basal planes and, hence, to a local change in symmetry.

All three methods can be consistently used to monitor strain that depends on the choice of substrate and other parameters. The high amount of stress incorporated in GaN hetero-expitaxial samples causes confusion as to assignment of the PL lines of donor bound excitons and donor-acceptor transitions. Homo-epitaxially grown GaN films provide a reference for unstrained films. The PL line positions of the donor acceptor pair transitions are found to exhibit a different stress coefficient than the excitonic line.

Large pores were formed at the interface between the oxide and the low Al content layer. Arenic accumulation near these pores, the interface, as well at the layer surface was found after, oxidation. This study showed that properties of this oxide might be enhanced by the properties of GaAs rich in As (similar to low-temperature-grown-GaAs).

Photoresponse measurements reveal that the carrier lifetime is reduced by the irradiation. The lifetimes scale inversely with the amount of singly ionized arsenic antisites which therefore is the main carrier trapping center and lifetime killer in irradiated GaAs. The density of charged arsenic antisites also determines the charge collection efficiency of Schottky diodes made of GaAs.

Due to their chemical nature, these extractants selectively complex americium and plutonium contaminants onto the particles, which can be recovered from the waste solution using a magnet. The effectiveness of the extractant-absorbed particles at removing transuranics (TRU) from simulated solutions and various nitric acid solutions was measured by gamma and liquid scintillation counting of plutonium and americium. The HNO3 concentration range was 0.01 to 6 M. The partition coefficients (Ka) for various actinides at 2 M HNO3 were determined to be between 3000 and 30,000. These values are larger than those projected for TRU recovery by traditional liquid/liquid extraction. Results from transmission electron microscopy indicated a large dependence of K-d On relative magnetite location within the polymer and the polymer surface area. Energy disperse spectroscopy demonstrated homogeneous metal complexation on the polymer surface with no metal clustering. The radiolytic stability of the particles was determined by using Co-60 gamma irradiation under various conditions. The results showed that K-d more strongly depends on the nitric acid dissolution rate of the magnetite than the gamma irradiation dose. Results of actinide separation from simulated high-level. waste representatives of that at various DOE sites are also discussed.

Magnetic microparticles (1-25 mu m) were coated with octyl (phenyl)-N,N-diisobutylcarbamoyl-methylphosphine oxide dissolved in tributyl phosphate and tested for removing TRU elements from acidic nitrate solutions. The particles were contacted with nitric acid solutions or simulated Hanford Plutonium Finishing Plant waste solution, irradiated with a high intensity Co-60 gamma-ray source, and evaluated for their effectiveness in removing TRU elements from 2 M HNO3 solutions. The resistance of the coatings and magnetic cores to radiolytic damage and hydrolytic degradation was investigated by irradiating samples of particles suspended in a variety of solutions with doses of up to 5 Mrad. Transmission electron microscopy, magnetic susceptibility measurements, and physical observations of the particles and suspension solutions were used to assess physical changes to the particles. Processes that affect the surface of the particles were found to dramatically alter the binding sites for TRU in solution. Hydrolysis played a larger role than radiolysis in the degradation of the extraction capacity of the particles.

Earlier studies of a-radiolysis using carbon tetrachloride rather than normal paraffinic hydrocarbons (NPH) as a diluent indicated greater resistance to radiation damage than observed, For this study, the TRUEX-NPH solvent was loaded with Am-241 in nitric acid, irradiated with doses up to 3.5 Mrad, and monitored for decline in extraction capability as a function of absorbed dose. Results of this study are being used to improve the Generic TRUEX Model, a thermodynamic model that permits flow-sheet design for solvent extraction processing.

Recent studies suggest that the beneficial effects of HTS on the circulation are primarily attributed to peripheral vasodilation and increases in plasma volume and myocardial contractility. In this article, we examine the relative importance of both nitric oxide (NO) and the autonomic nervous system (ANS) to the cardiovascular effects of HTS. When administered rapidly into either normovolemic or hypovolemic dogs, HTS caused a significant and transient hypotension prior to cardiovascular improvement. Mean arterial pressure decreased 49% within 1 min after the onset of HTS intravenous infusion at a rate greater than 1 ml/kg/min. This acute hypotensive response was not caused by cardiac depression and was independent of ANS function. Inhibition of NO synthase activity attenuated the initial decrease in blood pressure associated with rapid infusion suggesting an involvement of NO activity in the vascular effects of HTS. Infusion of HTS at 1 ml/min directly into the circumflex artery increased blood flow (by 64%) and regional myocardial contractility (percent of systolic shortening increased from 11 to 13%). The increases in myocardial blood flow and contractile function were observed in both normovolemic and hypovolemic animals. These responses were independent of ANS blockade. The NO inhibition attenuated the coronary vasodilation induced by HTS, but did not alter,contractile function. Intracoronary infusion of HTS at higher doses were associated with arrhythmias and transient myocardial depression. Laboratory studies suggest that NO synthase activity may play a role in mediating the vasodilator effect of HTS. However, NO inhibition does not alter the effects of HTS on myocardial contractile function.

The results can be equivalently obtained using singular value decomposition (SVD) of the cross-spectral density matrix. Using SVD suggests a new form of fractional coherence. The formulation as a SVD problem also suggests a way to order the inputs when a natural physical order of the inputs is absent. (C) 1996 John Wiley & Sons, Inc.

Some fundamental properties of the problem, as well as the convergence rates of certain newly developed algorithms for large-scale ELQP, are all related to gamma. In this paper, we derive an estimate of gamma for the ELQP problems resulting from discretization of an optimal control problem. We prove that the parameter gamma of the discretized problem is bounded independently of the number of subintervals in the discretization. C1 ARGONNE NATL LAB,DIV MATH & COMP SCI,ARGONNE,IL 60439.

Necessary and also sufficient conditions are developed for the existence or nonexistence of surfaces that are locally graphs over the base at the corner, with (prescribed) contact angles that may differ on the two sides. It is shown that the behavior can depart in significant qualitative ways from that which occurs when the two contact angles are the same. Conditions are derived under which such qualitative changes must occur, and illustrative examples are given. C1 UNIV CALIF BERKELEY,DEPT MATH,BERKELEY,CA 94720.

In the present work we examine the relation between the recursion in timestepping algorithms for semidiscrete systems of ODEs and certain types of iterative methods for solving discretized systems of equilibrium PDEs. We consider, in particular, the possibility of accelerating the ODE approach using recursions that are not time accurate together with parameter selection based on the theory of iterative methods. As one example, we take the parameters arising from the Chebyshev-type iterative methods and use them in a two-stage Runge-Kutta scheme. A comparison study for a representative steady-state diffusion problem indicates a dramatic improvement in convergence and efficiency. We remark that this approach can be trivially incorporated into existing One-integration codes to significant advantage. This yields a hybrid adaptive approach in a single code, C1 LOS ALAMOS NATL LAB,LOS ALAMOS,NM 87545. RP Lorber, AA (reprint author), UNIV TEXAS,CFD LAB,WRW 111,AUSTIN,TX 78712, USA.

This code simulates a wide variety of semiconductor devices by numerically solving the drift-diffusion equations. The most time-consuming aspect of the simulation is the solution of three Linear systems within each iteration of the Gummel method. The original version of DANCIR uses a conjugate gradient iteration preconditioned by an incomplete Cholesky factorization. In this paper, we consider the replacement of the Cholesky preconditioner by a multigrid preconditioner. To adapt the multigrid method to the drift-diffusion equations, interpolation, projection, and coarse grid discretization operators need to be developed. These operators must take into account a number of physical aspects that are present in typical devices: wide-scale variation in the partial differential equation (PDE) coefficients, small-scale phenomena such as contact points, and an oxide layer. Additionally, suitable relaxation procedures must be designed that give good smoothing numbers in the presence of anisotropic behavior. The resulting method is compared with the Cholesky preconditioner on a variety of devices in terms of iterations, storage, and run time. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

A variant of the cell-centered finite difference multigrid method of Ewing and Shen is implemented for solving the (large, sparse) linear subproblems. Numerical results are presented for one- and two-dimensional examples; in particular, the algorithm is applied to actual data obtained from confocal microscopy.

A model of the observed step configuration is proposed. Step bunching and growth of 6H-SiC(0001) layers and growth of 3C-SiC(111) islands were observed initially on the vicinal and the on-axis surfaces, respectively, of the latter set of films and controlled by the diffusion lengths of the adatoms. Independent control of continued step now growth of 6H or island growth of 3C-SiC on the terrace sites of the vicinal surface was achieved by changing the C2H4/Si2H6 gas flow rate ratio (=1, 2 and 10). Double positioning boundaries (DPBs) were observed using contrast imaging and lattice imaging via transmission electron microscopy (TEM) in the 3C-SiC as well as in 2H-AIN films grown on the vicinal 6H-SiC surfaces. The origin of the DPBs is the incoherency in bilayer stacking between the two materials at the 6H steps. By contrast, a very high quality ALN film without observable DPBs was pseudomorphically deposited on the on-axis 6H-SiC(0001) surface. C1 OAK RIDGE NATL LAB,DIV CHEM & ANALYT SCI,OAK RIDGE,TN 37831.

Methylsilane (MS) diluted in He was used as a precursor for deposition under conditions which produced a MS molecular beam with 0.365 eV translational energy. Films grown at temperatures between 1000 and 1150 degrees C and above approximate to 1200 degrees C were single crystal as judged by electron channeling, while those grown at intermediate temperatures were polycrystalline. Films grown at lower temperatures generally had a smoother surface morphology for moderate thicknesses, although all films showed at least some degree of faceting.

Using proximity rapid thermal annealing (10sec) the GaN surface retains both smooth morphology and its original stoichiometry. Variable temperature Hall measurements reveal approximate energy levels of 62meV for the implanted Si and 171meV for the Mg, which are similar to their values in epitaxially grown GaN. Implant isolation of both n- and p-type GaN, and n-type In0.75Al0.25N with multiple energy inert species (e.g. N+ or F+) produces high resistivity (greater than or equal to 10(8) Omega/rectangle) after subsequent annealing in the range 600-700 degrees C. Smaller increases in sheet resistance are observed for InxGa1-xN (x=0.33-0.75) under the same conditions due to the smaller energy bandgaps and the shallower energy levels of the damage-related states controlling the resistivity.

The objective of this study was to determine how soil pH (4.3-6.9), low total electrolyte concentration (TEC, 0.4-2.8 mol(c) m(-3)), and low Na adsorption ratios (SAR, 0.3-1.8 [mol(c) m(-3)](0.5)) affected the concentration of mobile colloids released from 13.5-m(3) reconstructed Ultisol profiles. Critical flocculation concentration (CFC, the minimum TEC to induce flocculation of a clay suspension) tests were conducted using the water-dispersible clay fraction of the Ap horizon of these profiles, which is the primary source for the mobile colloids. Surface soil pH, TEC, and SAR levels of the profiles that released high concentrations of colloids fell within the dispersion domain identified by the laboratory CFC tests. The effect of SAR on dispersion appears to be a continuum that approaches zero, and this effect is significantly (P less than or equal to 0.01) dependent on TEC. The dispersible nature of these soils is in part attributed to their very low TEC, generally < 2 mol(c) m(-3), which results from low concentrations of weatherable minerals. The TEC of 10 of the 13 profiles were < 2 mol(c) m(-3), the CFC for SAR = 1 (mol(c) m(-3))(0.5), indicating that if the pH is not limiting (pH greater than approximate to 6.0), colloidal dispersion will occur. Thus, these weathered soils can be highly dispersive within limited chemical conditions, and only small increases in SAR or pH may induce dispersion. By identifying these limits, the risk of enhancing subsurface contaminant transport by soil-derived mobile colloids can be reduced. C1 UNIV GEORGIA, DEPT CROP & SOIL SCI, ATHENS, GA 30602 USA.

Clay fractions were dominated by trioctahedral ferrous chlorite and dioctahedral mica (muscovite), with minor amounts of kaolinite, quartz, dolomite, and calcite. Goethite was also identified in the clay fraction of some soil horizons. The source of the phyllosilicates was inheritance from phyllite gravels in the alluvium and chemical dissolution of the dolostone releasing entrained clay minerals. Some portion of the kaolinite in surface horizons was probably the result of eolian additions. Goethite formation resulted from release of Fe from the chlorite. The extent of clay mineral inheritance, limited expansion of the chlorites, and lack of a chlorite or mica weathering product (vermiculite), as well as the presence of carbonates in the clay fractions, all suggest that these soils are still in the initial stages of weathering.

A data grid is a framework of uniformly spaced locations (grid points) for which data are available. Estimates of monthly averages of direct normal, diffuse horizontal, and global horizontal daily-total solar radiation energy (kWh/m(2)) are being made for each point on a grid covering the United States, Mexico, the Caribbean, and southern Canada. The grid points are separated by approximately 40 km. Using interpolation methods, the digital data grid can be used to estimate solar resources at any location. The most encouraging result to date has been the location of sources providing worldwide data for most of the input parameters required for modeling daily total solar radiation.

This paper provides several examples showing that not only is PV used widely in urban areas for applications such as traffic control, emergency warning and communication systems, flood control, irrigation, and lighting, but that PV is selected because its installed cost is less than the cost of connection to the local utility. PV can compete well in urban situations. However, all cost factors should be weighed by planners or engineers when considering the use of either PV or utility power for remote urban or rural applications.

The program consists of commitments to reduce emissions by individual electric utilities. The commitments are formalized in Participation Accords for large utilities and through Letters of Participation for small utilities (<50,000 customers). These utilities have committed to use renewable energy to avoid the emission of 3.6 million metric tons of carbon equivalent in the year 2000 that otherwise would have been emitted. The existence of Climate Challenge has helped assure the continuation of renewable energy projects at some utilities facing competitive pressures. The Climate Challenge program can be used by renewable energy developers interested in the utility market. Existing members may be interested in adding renewable energy commitments to their accords. Prospective members will be interested in the zero net greenhouse gas emissions of renewable energy electric generation.

The DOE PV budget, in contrast, declined 31% from $84 million to $60 million from FY95 to FY96. For industry, the challenge is to grow into new markets and applications that are expanding rapidly, using the substantial resources and capabilities they now possess. For the DOE program, the challenge is to continue an effective and productive role in advancing a booming industry. New budget realities and industry needs have led to a dialogue between DOE and industry that has helped clarify both industry and DOE's understanding of how both must adapt in order to continue a productive partnership.

We present here an overview of the solar wind speed and the variability in helium abundance, [He], for the entire mission to date, data on [He] in six high-latitude coronal mass ejections (CMEs), and a superposed epoch analysis of [He] variations at the seven heliospheric current sheet (HCS) crossings made during the rapid-latitude-scan portion of the mission. The differences in the variability of the solar wind speed and [He] in high-latitude and equatorial regions are quite striking. Solar wind speed is generally low but highly variable near the solar equator, while at higher latitudes the average speed is quite high (average speed around 760 km/s) with little variability. [He] can vary over nearly two decades at low solar latitudes, while at high latitudes it varies only slightly around an average value of similar to 4.3%. In contrast to the high [He] that is often associated with CMEs observed near the ecliptic, none of the six high-speed CMEs encountered at high southern heliographic latitudes showed any significant variation in helium content from average values. Reasons for this difference between high and low latitude CME observations are not yet understood. A superposed epoch analysis of the [He] during all seven HCS crossings made as Ulysses passed from the southern to northern solar hemisphere shows the expected [He] minimum near the crossing and a broad (+/-3 day) period of low [He] around the crossing time. We briefly discuss how our solar wind [He] observations may provide an accurate measure of the helium composition for all regions of the sun lying above the helium ionization zone.

At low solar latitudes and heliocentric distances beyond 3.37 AU Ulysses encountered seven intervals, ranging in duration from I hour to 22 hours, in which the suprathermal distributions included an antisunward field-aligned beam and a return population with a flux dropout typically spanning +/-60 degrees from the sunward field-aligned direction. Ail events occurred between the forward and reverse shocks or waves bounding corotating interaction regions (CIRs). The observations support a scenario in which the sunward-moving electrons result from reflection of the prevailing antisunward field-aligned beam at magnetic field compressions downstream from the spacecraft, with wide loss cones caused by the relatively weak mirror ratio. This hypothesis requires that the field magnitude within the CIRs actually increased locally with increasing field-aligned distance from the Sun.

Such reconnection is inherently 3-dimensional and naturally produces CMEs having magnetic flux rope topologies. Sustained reconnection behind CMEs can produce a mixture of open and disconnected field lines threading the CMEs. In contrast to the results of 2-dimensional reconnection, the disconnected field lines are attached to the outer heliosphere at both ends. A variety of solar and solar wind observations are consistent with the concept of sustained 3-dimensional reconnection within the magnetic legs of CMEs close to the Sun.

During times of quiet flow conditions electron-impact ionization rates were found to be generally low, of the order of 1% of the total ionization rates. However, just downstream of the strongest CME- and CIR-driven shock waves encountered by Ulysses, the electron impact-ionization rate at times was mom than 10% that of the charge-exchange rate for hydrogen and more than 100% that of the photoionization rate for helium.

In k-space, B-parallel to shifts the two QW dispersion curves relative to one another, resulting in an anticrossing and opening the energy gap. This gives rise to large B-parallel to-tunable distortions in the Fermi surface and density of states. This system is thus unique in that the Fermi surface and energy position of the gap can be controlled by sweeping B-parallel to. Recently, Lyo has predicted that m(c) undergoes large variations as the partial energy gap is moved through the Fermi level by B-parallel to. By tilting our sample by a small angle theta, we introduce a small perpendicular magnetic field B-perpendicular to, in addition to B-parallel to and analyze the temperature dependence of the resulting Shubnikov-de Haas oscillations to obtain m(c)(B-parallel to). Due to the strongly distorted dispersion near the gap, m(c) is suppressed by more than a factor of 3 near the upper gap edge, and enhanced by similar to 50% near the lower gap edge, in excellent agreement with the theory of Lye. We also observe the quantum Hall effect in a double QW at a high, constant B-parallel to. C1 OREGON STATE UNIV,PORTLAND,OR.

The re-equilibrium process obeys Fick's second law. By fitting the relaxation data to the solution of the diffusion equation with appropriate boundary conditions, we could determine the oxygen chemical diffusion coefficient and the activation energy. The oxygen diffusion coefficient is 8.9 x 10(-7) cm(2)/s at 900 degrees C and it increases with increase in temperature. Measured activation energy is 0.92 eV, which is slightly lower than that of other oxides in the system SrFe1-xCoxOy. C1 IIT,DEPT PHYS,CHICAGO,IL 60616.

The heat equation with the source term corresponding to the latent heat release due to solidification is calculated numerically by means of an implicit finite difference method. In the time stepping scheme, the evolution of solid fraction is deduced from a stochastic model of nucleation and growth which uses the local temperature (interpolated from the FDM mesh) to determine the local grain density and the local growth rate, The solid-liquid interface of each grain is tracked by using a subdivision of each grain perimeter in a large number of sectors. The state of each sector (i.e. whether it is still in contact with the liquid or already captured by an other grain) and the increase of radius of each grain during one time step allows one to compute the increase of solid fraction. As for deterministic models, the results of the model are the evolution of temperature and of solid fraction at any point of the sample. Moreover the model provides a complete picture of the microstructure, thus not limiting the microstructural information to the average grain density but allowing one to compute any stereological value of interest. We apply the model to the solidification of lamellar gray cast iron. C1 Univ Calif Los Alamos Natl Lab, Ctr Mat Sci, Los Alamos, NM 87545 USA.

This correlation is attributed, in part, to the extraction of the hydrated nitrate anion and its solvation by the diluent, facilitated by the high concentrations of dissolved water. Cation solvation by the diluent is also shown to play an important role in determining the efficiency of extraction. As was the case for strontium extraction by dicyclohexano-18-crown-6 and its derivatives, the highest distribution ratios for cesium are typically obtained for C-5 and C-6 alcohols and ketones.

The extractant solution combines octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO), diamyl(amyl)phosphonate (or tributylphosphate), and di(t-butylcyclohexano)-18-crown-6 in Isopar L, and is designed for simultaneous removal of strontium, technetium, lanthanides and actinides from radioactive wastes. The aqueous complexant is tetrahydrofuran-2,3,4,5-tetracarboxylic acid (THFTCA). In this report, the separation of UO22+ from Np(IV), Eu(III), Am(III), and Pu(IV) using the Combined Process Solvent has been optimized. Potentiometric titration and NMR spectroscopic results describe the distribution of THFTCA into the organic phase as a function of acidity and [THFTCA]. Further potentiometric titration experiments have determined the stoichiometry and stability of uranyl complexes in the aqueous phase. The thermodynamic data indicate that the uranyl complexes are anomalously weak which partially accounts for the selectivity. Ternary complexes involving UO22+ CMPO, and THFTCA in the extractant phase also appear to play a role. RP Nash, KL (reprint author), ARGONNE NATL LAB,DIV CHEM,9700 S CASS AVE,ARGONNE,IL 60439, USA.

This test involved 1) washing with water, 2) caustic leaching, 3) acid dissolution, 4) separation of transuranic elements (TRUs) by extraction with octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO), 5) separation of Sr by extraction with di-t-butylcyclohexano-18-crown-6, 6) separation of Cs from the acid-dissolved sludge solution by treatment with ammonium molybdophosphate (AMP), and 7) separation of Cs from the sludge wash and caustic leach solutions by ion exchange using a phenol-formaldehyde resin (CS-100). The results of the radionuclide separation steps indicated that the proposed flowsheet is a viable approach to pretreating the sludge stored in tank B-110. The TRUs, Sr-90, and Cs-137 were separated from the bulk of the sludge components, so that most of the mass of the sludge (containing Al, Bi, Fe, Na, etc.) could be disposed of as low-level waste.

Perrhenate K'(d) values were determined in 1.00 M NaNO3 from pH 2 to 13. The K'(d) values were determined in solutions containing 1.35 M NaNO3 and variable NaOH, 0.155 to 4.66 M, and in solutions containing 0.655 M NaOH and variable NaNO3, 0.46 to 5.35 M. Maximum perrhenate loadings were <2.7% of theoretical capacity. The K'(d) is defined by the following equation: K'(d)=Re-total-[Re](sol)xV(sol)/mass of dry resin/[Re](sol)xV(sol)/V-sol mL/g The total mmol of rhenium initially added is Re-total and [Re](sol) is the analytical molarity of rhenium in V-sol mL of solution after a batch contact. At 1.0 M HNO3 the value of K'(d) is 73 mL/g. The behavior of the perrhenate system in acid can be described by assuming that perrhenic acid, HReO4, is formed with a derived acid dissociation constant of about 6.5 M. In 1.00 M NaNO3 from pH 2 to 13 the sorption behavior is initially what is expected for a weak base resin with an acid dissociation constant of 1.24 x 10(-5) M. Thus, the K'(d) value decreases with pH values above the pK(a) value. However, instead of the value of K'(d) decreasing to zero at higher pH values, it becomes constant at 15 mL/g. In a solution containing 1.00 M NaOH and 1.00 M NaNO3, the value of K'(d) is 25 mL/g. The unusual behavior of the Reillex(TM)-HP anion exchange resin suggests that the resin's unprotonated pyridine functionality is solvating a {Na+,ReO4-} ion pair. The interaction of the perrhenate ion with Reillex(TM)-HP is more involved than a simple ion exchange phenomenon and the presence of NaOH affects the resin-perrhenate interactions.

Compounds incorporating a 21-crown-7 moiety are shown to exhibit greater cesium/sodium selectivity, superior functional stability, and better compatibility with PUREX-like diluents than dibenzocrown ethers with other ring sizes. The cesium distribution ratios obtained with these compounds, however, are generally not large enough to be of practical value. Higher D-C5 values are achieved with several dibenzo-18-crown-6 derivatives. Of these, the best results are achieved with 4,4'(5')-di[(1-hydroxy-2-ethylhexyl)benzo]-18-crown-6. The distribution ratios obtained with this compound in undiluted tri-n-butyl phophate (TBP) compare favorably with those reported for synergistic systems combining a crown ether with the anion of a lipophilic organic acid.

Simultaneous uptake of cationic and anionic species SO SOLVENT EXTRACTION AND ION EXCHANGE LA English DT Article ID ACID DEPENDENCIES AB The uptake of tri-, tetra- and hexa-valent actinides as well as of pertechnetate actions by some new multifunctional ion exchange resins has been investigated. The new resins, identified as Diphonix A, for anionic Diphonix, contain the same geminally substituted diphosphonic acid groups bonded to a styrenic-based polymer matrix as the regular Diphonix resin, plus strong base anion exchange groups such as the tetraalkylammonium (Diphonix A - Type 1 resins) or the quaternized pyridinium (Diphonix A - Type 2 resins) groups. Our uptake measurements have shown that the Type 2 Diphonix A resins are as effective as the regular Diphonix resin in the rapid uptake of actinides from acidic solutions, while at the same time sorbing pertechnetate anions in a manner comparable to existing commercial anion exchange resins. The failure of the Type 1 Diphonix A resins to perform equally well has been explained as a consequence of the mutual interaction of adjacent diphosphonic acid groups and tetraalkylammonium groups. Uptake data have also been obtained with Se(IV). The behavior of the Diphonix A resins toward Se(IV) uptake in acidic solutions is comparable to that of commercial anion exchange resins.

P,P'-di(2-ethylhexyl) methanediphosphonic acid SO SOLVENT EXTRACTION AND ION EXCHANGE LA English DT Article ID EXCHANGE AB Two novel extractants, P,P'-di(2-ethylhexyl) methanediphosphonic acid (H(2)DEH[MDP]) and P,P'-dioctyl methanediphosphonic acid (H2DO[MDP]) have been synthesized at high purity and yield. H(2)DEH[MDP] was selected for metal extraction studies because of its better physical properties. An investigation of the extraction of alkaline earth cations, Fe(III) and representative tri-, tetra- and hexavalent actinide ions from nitric acid solutions into o-xylene solutions of H(2)DEH[MDP] at different concentrations was performed. With a few exceptions, the acid dependencies of the extraction of the above metal species strongly resembles those measured in the uptake of the same metals by the chelating ion exchange resin Diphonix(R), which contains gemdiphosphonic acid groups chemically attached to a polymeric matrix. H(2)DEH[MDP] exhibits practically no selectivity among the alkaline earth cations. The almost lack of acid dependency observed with Fe(lll) and tetra- and hexavalent actinides indicates that these ions are chelated by H(2)DEH[MDP] mostly through the P=O groups of the extractant. With Fe(lll) and the actinides, variable slopes of the extractant dependencies were measured, their values being strongly dependent on the acidity of the aqueous phase. Typically, the slope of the extractant dependency has a value of about two if the metal is extracted from high acidity solutions. This value becomes progressively lower as the aqueous acidity is reduced, tending to almost zero for acidities around 0.1 (M) under bar. This phenomenon has been attributed to the formation of metal complexes having different stoichiometries, ligand protonation and solubility in the aqueous phase. H(2)DEH[MDP] possesses an extraordinary affinity for actinides and Fe(lll). In analogy with the Diphonix resin, this property can be exploited for actinide preconcentration and separation from complex matrices of analytical interest and from mixed waste solutions.

The new resins behave as an ABS: in the presence of high ionic strength solutions of water-structuring anions (e.g., SO42-, CO32-, OH-, etc.), chaotropic ions (e.g., TcO4-) are retained. Stripping is accomplished by washing the resins with water, thus lowering the ionic strength and no longer mimicking an ABS environment. Monomethylated PEGs (Me-PEGs) of average molecular weight 350, 750, 2000, and 5000 have been grafted to chloromethylated polystyrene-1%-divinylbenzene. Quantitative uptake of tracer-scale pertechnetare has been achieved from NaOH, (NH4)(2)SO4, K2CO3, and K3PO4 for the two higher molecular weight PEG resins, with retention increasing as the molecular weight of the grafted Me-PEG increases. No uptake is observed from water. The relationship between partitioning of solutes in liquid/liquid ABS and retention by the ABEC resins has been confirmed by the following observations. The conditions necessary for ABS extraction are necessary for ABEC uptake and the trends in partitioning behavior observed for ABS are also observed for ABEC. Resin uptake of TcO4- increases as the concentration of water-structuring salt increases, as the Delta G(hyd) of the water-structuring anion becomes more negative (for a given concentration of salt solution), and as the molecular weight of the supported polymer increases. No uptake occurs from salt solutions that do not contain a sufficient concentration of biphase-forming salt. C1 ARGONNE NATL LAB,DIV CHEM,ARGONNE,IL 60439.

Silica grafted diphosphonic acid SO SOLVENT EXTRACTION AND ION EXCHANGE LA English DT Article ID DEPENDENCIES; ACTINIDES AB A new chelating ion exchange resin, Diphonix(R), containing geminally substituted diphosphonic acid ligands bonded to a styrene-based polymeric matrix, was recently developed and characterized. To overcome some of the problems associated with the stripping of actinide elements from the resin, a new version of the Diphonix resin has been prepared, where the chelating diphosphonic acid groups are grafted to a silica support. The new material is called Diphosil, for Diphonix on silica. The properties of the new material have been investigated with regard to its equilibrium and kinetic behavior in the uptake of actinide and other ions from acidic solutions. In this work data comparing the Diphonix and Diphosil resins are presented and discussed. The Diphosil resin appears particularly well suited for those cases where the recovery and further processing of the sorbed actinides is not required and the loaded resin can be considered as a solid waste. Because about 90 % of the Diphosil resin weight is silica, the problem of possible generation of gaseous compounds due to the slow radiolytical degradation of the organic components of the resin is minimized.

We then used these data to help us make a more definitive assignment that has been previously possible of the features in the low-temperature IR conductivity spectra of (BEDT-TTF)(2)Cu[N(CN)(2)]Br. It was also necessary to measure the low-temperature IR conductivity of additional isotopic analogs of BEDT-TTF, namely those containing C-13(6), C-13(2), S-34(8) and d(8). We found, as expected, that the spectra are dominated by the electron-phonon activated totally symmetric (A(g)) modes, but also that the nature of the strongest of these, nu(3)(A(g)), is changed dramatically in (BEDT-TTF)(2)Cu[N(CN)(2)]Br from what it is in neutral BEDT-TTF. We also found, unexpectedly, that one of the stronger IR features is most likely due to an activated non-totally-symmetric (B-3g) mode, instead of a normally IR-active mode, which had been previously assigned, and further that several other (B-3g) modes appear to be activated in the IR spectra.

In this paper, the TRUST algorithms are generalized by extending the formalism to lower semicontinuous objective functions, and by allowing gradient-directed tunneling with componentwise how direction reversal at the boundaries of the parameter domain. Known Limitations of the methodology are summarized, and the reduction of a multi-dimensional problem to a one-dimensional case (e.g., via hyperspiral embedding) is discussed with regards to a formal convergence proof. Benchmark results are presented, which demonstrate that TRUST is substantially faster than previously published. global optimization techniques.

In Ni3Al, boron additions were found to segregate to dislocations, low angle boundaries, stacking faults, antiphase boundaries, and grain boundaries. The boron and aluminum levels at grain boundaries were found to vary both from boundary to boundary and also along an individual boundary segment. In some cases, a boron-enriched film up to similar to 3 nm thick was observed. In aluminum-enriched Ni3Al, ultrafine clusters containing up to approximately 10 boron atoms were detected in the matrix. In contrast, the majority of the boron additions in NiAl was determined to be in the form of ultrafine MB2-type precipitates. These precipitates offset the benefits of the boron segregation to the high angle grain boundaries. In molybdenum-doped NiAl, atom probe analyses indicated extremely low solubilities of the molybdenum and other trace impurities in the matrix and significant enrichments of molybdenum, nitrogen and silicon, boron, and iron at the grain boundaries. In boron-doped two phase alpha(2)+gamma containing chromium, niobium, and tungsten, the boron level was found to be significantly depleted from the bulk level in both the alpha(2) and gamma phases and a variety of coarse borides including TiB, TiB2 and a finer chromium-enriched (Ti,Cr)(2)B precipitate was observed. The tungsten and chromium were determined to partition preferentially to the alpha(2) phase and also to segregate to the alpha(2)-gamma and gamma-gamma interfaces. These results indicate that a significant proportion of the microalloying elements are consumed by the boride precipitates. C1 Oak Ridge Natl Lab, Div Met & Ceram, Oak Ridge, TN 37831 USA.

The deformation of the FL-TiAl alloy at the primary creep stage is mainly accommodated by the movement of lattice dislocations in the (111)(gamma) easy-glide planes and interfacial dislocations in the gamma/gamma and gamma/alpha(2) interfaces. When the alloy is deformed into the secondary creep stage, the density of interfacial dislocations continues to increase and deformation twins nucleate and grow from the lamellar interfaces. It is suggested that deformation twinning in lamellar TiAl can be viewed as a stress-relief process due to the pile-up of interfacial dislocations gliding along the lamellar interfaces during deformation. The deformation twins in gamma lamellae are accordingly formed as a result of a interfacial dislocation reaction based upon a stair-rod cross-slip mechanism. The FL-TiAl alloys become more resistant to creep deformation after prestraining is due mainly to the sessile stair-rod dislocations formed at the intersection between the deformation twin and gamma or alpha(2) lamella. These stair-rod dislocations act as effective barriers for the movement of interfacial dislocations during deformation. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94551 USA.

The yield stress of the PST-TiAl crystal was found to exhibit a positive-concave-up dependence upon the lamellar interface tilting angle (Phi) with a minimum at Phi=45 degrees at high-strain rates. The yield stress of the duplex gamma-TiAl alloy showed two distinct yield stress-temperature dependencies at temperatures >600 degrees C: an anomalous temperature dependence for strain rates >1 s(-1) and a negative temperature dependence for strain rates <1 s(-1). Three temperature regimes of plastic flow behavior were identified for the duplex gamma-TiAl alloy. Translamellar microcracks in the PST-TiAl crystals were identified to be mode-I cracks while the interlamellar microcracks were seen to be a mixture of mode-II and mode-III. Grain interior microcracks observed in duplex gamma-TiAl alloy are formed by shear displacement while grain boundary microcracks are formed by the strain mismatch between grains and grain boundary deformation.

These lamellar microstructures consist of very fine laths of the gamma and alpha(2) phases, with average interlamellar spacings (lambda(L)) of 100 nm and alpha(2)-alpha(2) spacings (lambda(alpha)) Of 200 nm, and are dominated by gamma/alpha(2), interfaces. This ultrafine lamellar structure remains stable during heat-treatment at 900 degrees C for 2 h, but becomes unstable after 4 h at 982 degrees C. The ultrafine lamellar structure remains relatively stable in both alloys after aging for >5000 h at 800 degrees C, but disappears completely at 1000 degrees C. Continuous coarsening of the lamellar structure begins with the dissolution of fine alpha(2) lamellea. The aged Ta-modified alloy shows similar lamellar coarsening behavior within the colonies, but has more discontinuous coarsening of the intercolony gamma with new precipitation of coarse alpha(2) and beta phase particles. Analytical electron microscopy (AEM) microcompositional data shows that changes In composition of the alpha(2) phase correlate with microstructural instability.

Both intrinsic factors (e.g., alloy stoichiometry), and extrinsic factors (e.g., environment) have been shown to affect their mechanical properties. Of all the recent developments, perhaps the most significant is the realization that Ni3Al and FeAl are intrinsically ductile (at least on the Al-deficient side of stoichiometry); their brittleness when tested in ambient air is due mainly to environmental embrittlement. Another intriguing discovery is that boron embrittles Ni3Al in gaseous hydrogen (until recently, B was thought to have only beneficial, or at most neutral, effects). We review these and other recent discoveries and discuss, wherever possible, the underlying physical mechanisms giving rise to the observed mechanical behavior.

Inadequate consideration has been made of the fact the system is cooling dominated and that the amount of cooling tends to increase as the emissive cooling area expands during the process. Experimental evidence suggests that during processing, this increased cooling causes the solidification interface to move away from the baffle and become curved. The motion of the interface results in a decrease in the solidification gradient. The combination of these actions can result in variations in PDAS, grain misalignment and the production of defects. It is shown that despite this tendency, microstructural stabilization may be achieved through the use of the heat of fusion as an internal process heat source.(1) C1 Sandia Natl Labs, Albuquerque, NM 87185 USA.

These are: electrode gap, melt rate, cooling rate, furnace annulus, furnace atmosphere and electrode quality (i.e. cleanliness and integrity). Of these variables, active, closed loop control is usually applied only to electrode gap. Other variables are controlled by controlling furnace operational parameters to preset schedules (e.g. melting current is ramped or held constant to control melt rate in an open loop fashion), through proper maintenance and calibration of equipment (e.g. to ensure proper cooling water and gas flow rates, or to accomplish an acceptable vacuum leak rate), through proper practice of procedures, and by maintaining electrode quality control. Electrode gap control is accomplished by controlling an electrode gap indicator such as drip-short frequency (or period) to a specified set-point. This type of control, though often adequate, ignores information available from other electrode gap indicators and is susceptible to upsets. A multiple input electrode gap controller is described which uses optimal estimation techniques to address this problem. C1 Sandia Natl Labs, Dept Mat Proc, Albuquerque, NM 87185 USA.

One possible mechanism to explain this property improvement relies on the boron and phosphorus additions slowing down the growth of gamma " and y' precipitates during high temperature service or aging. However, atom probe analysis found no segregation of boron and phosphorus to gamma-gamma " or to gamma-gamma' interfaces in the alloys with the high boron and high phosphorous levels. No difference in growth rates were found by transmission electron microscopy in the sizes of the gamma " or gamma' in alloys with high phosphorus and high boron as compared to commercial alloys and to alloys with even lower levels of phosphorus and boron. Atom probe analysis further found that much of the phosphorus, boron, and carbon segregated to grain boundaries. Creep curves comparing the alloys with high levels of phosphorus and boron and alloys with low levels of phosphorus and boron show a large difference in strain rate in the first hours of the test. These results suggest that the boron and phosphorus may have a direct effect on dislocation mobility by some pinning mechanism. C1 Oak Ridge Natl Lab, Oak Ridge, TN 37831 USA.

With the TOP500 report now generally and easily available it is possible to present an analysis of the state of High Performance Computing (HPC) in the U.S. This note summarizes some of the most important observations about HPC in the U.S. as of late 1995, in particular the continued dominance of the world market in HPC by the U.S. the market penetration by commodity microprocessor based systems, and the growing industrial use of supercomputers.

Using this technique, a conventionally processed epitaxial layer structure is inverted and epoxied to a new host substrate. The original substrate is removed leaving only the original epitaxial structure expoxied to the host substrate. The exposed backside of the epitaxial structure may then be processed. Because the structures fabricated using this technique are so thin, mesas, Schottky gates, and ohmic contacts may be defined in close proximity both above and below the active device layers.

MB is a failure of semiclassical theory that occurs when a magnetic field causes electrons to tunnel across a gap in k-space from one Fermi surface (FS) branch to another. We study MB in a two-branch FS created by subjecting a DQW to an in-plane magnetic field (B-parallel to). The principal effect of B-parallel to is a distortion in the dispersion curve of the system, yielding a FS consisting of two components, a lens-shaped inner orbit and an hour-glass-shaped outer orbit. The perpendicular field (B-perpendicular to) causes Landau level formation and Shubnikov-de Haas (SdH) oscillations for each branch of the FS. At higher perpendicular fields MB occurs and electrons tunnel through k-space from one FS orbit to the other. MB is observed by noting which peaks are present in the Fourier power spectrum of the magnetoresistance versus 1/B-perpendicular to at constant B-parallel to. We observe MB in two DQW samples over a range of B-parallel to. (C) 1996 Academic Press Limited C1 LUCENT TECHNOL, MURRAY HILL, NJ 07974 USA. OREGON STATE UNIV, CORVALLIS, OR 97331 USA.

Molecular mechanics calculations are used to examine the degree of strain that develops in five-membered, aliphatic chelate rings of ethers and amines as a function of the size and charge of the metal ion. Although five-membered chelate rings that contain saturated neutral oxygen donors are found to exhibit an inherent steric preference for targe metal ions, experimental evidence suggests that for the majority of cases where enhanced selectivity for larger metal ions has been observed after the addition of neutral oxygen donors, the selectivity enhancement is largely the result of steric and inductive changes to other donor groups in the ligand, e.g. amines, rather than the result of increasing the denticity of the ligand.

The ring shear tests involve forcing a rod with premachined rings of thick electrodeposit through a hardened steel die having a hole with a diameter greater than that of the rod but less than that of the rod plus coating. The I-beam tests provide a method for resting adhesion in a tensile fashion and simulate conditions some of the plated parts would see in service. Results with Invar revealed acceptable adhesion with a process that included a Wood's nickel strike. Higher adhesion values were obtained with VascoMax C-200 with use of anodic treatment in phosphoric acid followed by cathodic treatment in sulfuric acid or anodic treatment in sulfuric acid followed by a Wood's nickel strike. Similarly, highest adhesion values were obtained with 440C stainless steel when anodic treatment in sulfuric acid and Wood's nickel striking were used.

The films are required to be transparent to r.f. fields particularly in the range 1-1.25 GHz, UHV compatible, and very adhesive even after a number of baking cycles. Usual techniques such as wet-chemical coating do not fulfil the requirements for UHV compatibility. A cathodic are plasma source with a copper cathode was operated in an oxygen atmosphere to form CuO films on the substrate, which was either the anode or was mounted on a substrate holder using a separate anode. The films are single-phase polycrystalline CuO. They are slightly oxygen-rich, adhere very well (pull strength exceeding 85 MPa) and fulfil all UHV requirements. The deposition method is very efficient, and large workpieces up to a surface area of 5000 cm(2) have been coated. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,BERKELEY,CA 94720.

At higher source-drain bias these Coulomb oscillations develop sharp overstructure, which arises from the alignment and de-alignment of quantized energy levels of the two dots.

LEED and STM show that two metals interacting on a surface can form compounds with structures not seen in bulk alloys. Many novel phenomena related to the kinetics of growth of metals on metals have been discovered. The knowledge gathered in this area provides a solid basis for the synthesis of new materials with applications in areas of catalysis, electro-chemistry and microelectronics. In many cases, the formation of a surface bimetallic bond induces large changes in the band structure of the metals. For surfaces that contain transition or s,p metals, the strongest metal-metal interactions occur in systems that combine a metal with a valence band almost fully occupied and a metal in which the valence band is almost empty. A very good correlation is found between the electronic perturbations in a bimetallic system and its cohesive energy. Bimetallic bonds that display a large stability usually involve a significant redistribution of charge around the metal centers. The electronic perturbations affect the reactivity of the bonded metals toward small molecules (GO, NO, H-2, O-2, S-2, C2H4, CH3OH, etc.), For supported monolayers of Ni, Pd, Pt and Cu a correlation is observed between the shifts in surface core-level binding energies and changes in the desorption temperature of CO from the metal adlayers. Examples are provided which demonstrate the utility of single-crystal studies for understanding the role of ''ensemble'' and ''ligand'' effects in bimetallic catalysts.

We explain how a supersymmetry-inspired organization works well in conjunction with other tools, namely the color and helicity decompositions of amplitudes, and the constraints imposed by perturbative unitarity and collinear singularities. String theory seems most useful as a heuristic guide. Using these techniques, the complete set of one-loop five-parton QCD amplitudes, as well as certain sequences of special helicity amplitudes with an arbitrary number of external gluons, have been obtained.

This was accomplished using the technique of in vivo, extracellular single unit recording in anesthetized rats. The intravenous (i.v.) administration of CP 96,345 (0.01-1.28 mg/kg) did not significantly alter the firing rate of spontaneously active DA neurons in the SNC and VTA areas. The acute administration of 5 or 10 mg/kg, i.p., of CP 96,345 produced a significant decrease in the number of spontaneously active SNC and VTA dopamine cells compared to vehicle-treated rats. In contrast to its effect on the number of spontaneously active DA neurons, the administration of 5 mg/kg, i.p., of CP 96,345 did not significantly alter the basal firing pattern of either SNC or VTA DA neurons. The acute administration of CP 96,345 (10 mg/kg, i.p.) significantly potentiated the suppressant action of (+)-apomorphine on the basal firing rate of spontaneously active SNC and VTA DA cells. The chronic administration of CP 96,345 (5 or 10 mg/kg, i.p.) for 21 days also produced a significant decrease in the number of spontaneously active SNC and VTA DA cells compared to vehicle controls. This effect was not reversed by the systemic administration of(+)-apomorphine (50 mu g/kg, i.v.), suggesting that the reduction in the number of spontaneously active DA cells produced by CP 96,345 is probably not the result of depolarization inactivation. Overall, our results indicate that the tonic activation of NK1 receptors by substance P may be necessary to maintain the spontaneous activity of a proportion of midbrain DA neurons.

We also determined the effect of PCPA administration on the spike discharge pattern of midbrain DA cells. This was accomplished using standard extracellular single cell recording techniques. The administration of PCPA (400 mg/kg, i.p., 24 h before the experiment) produced a significant decrease in the number of spontaneously active DA cells in both the A9 (52%) and A10 (63%) areas compared to controls. The burst firing analysis indicated that there was a significant increase in the mean interspike interval of A9 and A10 DA neurons in PCPA treated animals compared to controls. Furthermore, a decrease in the percentage of A10 DA neurons exhibiting a burst firing pattern and the number of bursts was observed in the PCPA treated animals compared to controls. The intravenous (i.v.) administration of 5-hydroxytryptophan (40 mg/kg) and the peripheral aromatic acid decarboxylase inhibitor benserazide (10 mg/kg) which restores 5-HT content, reversed the decrease in the number of spontaneously active A9 and A10 DA neurons, as well as the decrease in the percentage of A10 DA neurons exhibiting a bursting pattern. In contrast, the i.v. administration of benserazide (10 mg/kg) and L-DOPA (40 mg/kg) did not reverse the decrease in the number of spontaneously active midbrain DA neurons produced by PCPA treatment. The pretreatment of animals with PCPA did not alter the sensitivity of spontaneously active A9 or A10 DA cells to the intravenous administration of (+)-apomorphine (1-32 mu g/kg) compared to controls. Overall, our results indicate that the depletion of brain 5-HT by PCPA produces a decrease in the activity of midbrain DA cells, suggesting that endogenous 5-HT is required to maintain DA tone.

We find evidence for photoinduced polarons (photoexcited 'radical ions') having spin 1/2, with two absorption bands at 0.80 and 1.54 eV, respectively, and with negative PADMR signal at g similar or equal to 2. Similar absorption bands are observed in lightly p-doped 6T, and are interpreted as due to 6T(.+) radical cations. In addition, a photoinduced absorption band is found at about 1.1 eV, which is shorter lived and decreases faster with increasing temperature than the polaron bands. We identify this band as due to spinless bipolarons (photoexcited 'di-ions'). A similar di-cation band has been identified in heavily p-doped 6T. Finally, we have identified triplet excitons (S=1) with triplet-triplet transition energy at about 1.45 eV. C1 TECHNION ISRAEL INST TECHNOL,INST SOLID STATE,IL-32000 HAIFA,ISRAEL.

The effects of sinter time, temperature and ramp rate; hot isostatic pressing (HIP) temperature and time; and powder oxygen content on consolidation density, kinetics, microstructure, crystallographic texture, and mechanical properties have been evaluated. In general, higher temperatures and longer hold times resulted in higher density compacts with larger grain sizes for both sintering and HIP'ing. HIP'ed compacts were consistently higher in density than sintered products. The higher oxygen content powders resulted in finer grained, higher density HIP'ed products than the low oxygen powders. Texture analysis showed that the isostatically processed powder products demonstrated a near random texture. This resulted in isotropic properties in the final product. Mechanical testing results showed that the HIP'ed powder products had consistently higher flow stresses than conventionally produced plates, and the sintered compacts were comparable to the plate material. A micromechanics model (Ashby HIP model) has been employed to predict the mechanisms active in the consolidation processes of cold isostatic pressing (CIP), HIP and sintering. This model also predicts the density of the end product and whether grain growth should be expected under the applied processing conditions. The model predicted the densification and mechanisms well for the higher oxygen content powder using the initial parameters. However, the model consistently underpredicted the densification of the lower oxygen content powder. Modifications to the room temperature yield strength, surface energy and diffusion terms in the model yielded closer agreement. The model predicted the grain growth observed at the higher sintering temperatures and long sinter times only after the tuning was completed.

The stress-strain behavior of several tantalums, possessing varied compositions and manufacturing histories, and tantalum alloyed with tungsten, was investigated as a function of temperature from -196 degrees C to 1000 degrees C, and strain rate from 10(-3) s(-1) to 8000 s(-1). The yield stress for all the Ta-materials was found to be sensitive to the test temperature, the impurity and solute contents; however, the strain hardening remained very similar for various "pure" tantalums but increased with alloying. Powder-metallurgy (P/M) tantalum with various levels of oxygen content produced via different processing paths was also investigated. Similar mechanical properties compared to conventionally processed tantalums were achieved in the P/M Ta. This data suggests that the frequently observed inhomogeneities in the mechanical behavior of tantalum inherited from conventional processes can be overcome. Constitutive relations based upon the Johnson-Cook, the Zerilli-Armstrong, and the Mechanical Threshold Stress models were evaluated for all the Ta-based materials. Parameters were also fit for these models to a tantalum-bar material. Flow stresses of a Ta bar stock subjected to a large-strain deformation of epsilon=1.85 via multiple upset forging were obtained. The capabilities and limitations of each model for large-strain applications are examined. The deformation mechanisms controlling high-rate plasticity in tantalum are revisited.

The test material was shocked to 45 GPa for 1.8 mu s and soft-recovered such that deformation that occurred during this procedure was predominantly due to the shock loading. Mechanical characterization of the annealed and shock-recovered tantalum was performed over a wide range of strain rates (10(-3) to 7000 s(-1)) in compression. Shock prestraining caused an increase in the yield and flow stress in all of the test materials. The test results suggest that the athermal component of the flow stress is altered and to some extent work hardening is exhausted. The effects of shock prestrain on the microstructure and substructure of the test material were examined using optical microscopy, which revealed features which may be deformation twins. The results of these examinations and how they correlate with the effects of shock prestrain on mechanical behavior are discussed. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

However, fewer detailed studies have examined the evolution of crystallographic texture and the mechanical response of tantalum bar or rod material following prestraining to large strains epsilon > 1. In this paper the influence of large plastic prestraining on the microstructure evolution, texture evolution, and mechanical response of high-purity tantalum bar material is presented. Tantalum cylinders annealed at 1050 degrees C were quasi-statically upset forged, with intermediate lubrication, to true strains of 0.4, 0.95, and 1.85. Microstructural and textural banding within the starting Ta-bar was characterized in detail. It was found that different oriented bands evolved differently during large-strain forging leading to significant scatter in the mechanical response. Aspects of defect storage, work-hardening response, and texture evolution in Ta-bar as a function of forging strain are discussed. C1 Univ Calif Los Alamos Natl Lab, Los Alamos, NM 87545 USA.

The observed dislocation structure includes medium to high angle lamellar boundaries parallel to the rolling plane surrounding either groups of cells or arrays of loosely knit dislocations and equiaxed subgrains. The distributions of local orientations between individual dislocation boundaries and their angle/axis pairs have been measured using convergent beam Kikuchi analysis. The local orientations are compared to the experimental macroscopic texture and to the predicted texture using a Taylor polycrystal model. The sequence of near neighbor orientations shows that individual grains subdivide across their thickness into two to four different texture components separated by sharp high angle boundaries. Although the arrangement of local orientations is much more diverse than suggested by polycrystal models and single crystal studies, their average is similar to the Taylor prediction.

The need for new lower temperature processes and hence new precursor chemicals will be examined and explained.

The limited number of melting techniques for these materials are the result of the high melting temperatures and reactivity with conventional mold/crucible materials. In addition, the required vacuum levels used in the EB and VAR processes, limit these techniques to relatively low interstitial content material due to extensive outgassing during melting. Plasma arc melting(PAM) provides an alternative for melting tantalum and offers the advantage of processing under inert or other gases rather than vacuum. The plasma process is not sensitive to material outgassing and allows for the direct recycling of material that would otherwise be reprocessed by chemical extraction. The current work examines melting of high interstitial content tantalum powder by the plasma are process.

Institutional arrangements necessary to assess these changes and make decision makers aware of the consequences have not necessarily adapted to these world conditions. In response to this leading technology assessment and forecasting institutions formed an international association of technology assessment and forecasting institutions to assist in the diffusion of technology assessment in the decision-making process. This paper discusses the origins of the International Association of Technology Assessment and Forecasting Institutions (IATAFI) and the goals and vision for the organization. The following articles represent some of the topics discussed at the first IATAFI conference in Bergen, Norway in May 1994.

The selective use of federal policy, tools and resources for enhancing economic competitiveness and for providing ''sustainable'' economic development is proposed. A novel approach to a coherent national R&D strategy is advocated with three major components: tax credits, technology facilitation, and federal investment directed towards sustainable competitive participation. Sustainable competitive participation is based on the blending of the concepts of economic competitiveness and sustainable development. Four sectors of technology development and competitiveness are considered for this comprehensive national science and technology strategy. Several examples illustrate are the appropriate federal government and national laboratory role in sustainable competitive participation.

However, this material has a number of environmental drawbacks which make it unacceptable for future use from both processing and disposal. Electrical grade polysulfide contains lead oxide, a hazardous material which will potentially undergo very strict regulations (Lead Exposure Reduction under the Clean Air Act of 1991) in the near future. Also, it has cure rate which is sensitive to humidity. The excess material from processing must be disposed of as a hazardous waste and the cure rate conditions are uncontrollable because vendors are unable to obtain consistent lead oxide. An interagency government task force was formed in late 1992 to develop a lead-free drop-in material, i.e., an environmentally safe material meeting as many of the desirable material and processing characteristics as possible. We report on the interagency progress and discuss two property measurement techniques that allow rapid screening of potential drop-in replacements.

A. cationic photoinitiator at a concentration of 1-3 parts per hundred of the epoxy resin is required for this process. However, these materials tend to be brittle. In order to increase the fracture toughness (K-IC) of the EB cured materials, a variety of toughening agents were incorporated into the epoxy resin/photoinitiator blend in concentrations ranging from 5 - 30 percent. High molecular weight thermoplastics such as Udel P-1700, Rader A-200, and Ultem 1000 and hydroxy-terminated polysulfone oligomers nearly doubled K-IC with no reduction in glass transition temperature. Viscosities of the thermoplastic/epoxy resin/photoinitiator blends were extremely high. Reactive flexibilizers and rubbers also provided tougher materials, but sometimes with reduction in glass transition temperature. For example, a blend of 10 percent Shell Kraton FG 1901 X (a maleic anhydride terminated SEES copolymer) with Dow Tactix 123 (bisphenol A epoxy) containing 3 phr (4-octyloxyphenyl) phenyliodonium hexafluoroantimonate was irradiated at a total dosage of 150 kGy. Glass transition temperature (tan delta) of the cured material was 171 degrees C and the K-IC was 0.92 MPa . m(1/2).

Since E-beam curing is a nonthermal curing method, the use of lower cost, low temperature tools made of foam, wood, or other materials becomes possible. As part of the CRADA, E-beam irradiation/stability studies on low-cost EB tooling have been performed. Approximately 50 potential tooling materials representing a broad cross-section of both commonly used and specialty materials were tested. Coupons from each material were exposed to the equivalent of 5 E-beam curing cycles of 75 kGy each. At the conclusion of each 5-cycle exposure set, the materials were evaluated for dimensional and hardness changes. The testing continued for each material until obvious breakdown from radiation exposure or handling. The goal is ultimately to extend testing to approximately 150 simulated cure cycles (11,250 kGy) which represents a fairly large aircraft/aerospace structure production run.

Spectral data from the surfaces of a host of practical materials may be obtained with sufficient insensitivity to characterize relatively thick films, such as paint, and the potential exists to detect very thin films, such as trace oil contamination on metals. The SOC 400 Surface Inspection Machine/InfraRed (SIMIR) has been developed as a nondestructive inspection tool to exploit this potential in practical situations. This SIIR is a complete and ruggidized Fourier transform infrared spectrometer with a very efficient and robust barrel ellipse diffuse reflectance optical collection system and operating software system. The SIMIR weighs less than 8 Kg, occupies less than 14 L volume, and may be manipulated into any orientation during operation. The surface to be inspected is placed at the focal point of the SIM/IR by manipulating the SIMIR or the surface. The SIMIR may or may not contact the surface being inspected. For flat or convex items, there are no size limits to items being inspected. For concave surfaces, the SIMIR geometry limits the surface to those having a radius of curvature greater than 0.2 m. For highly reflective metal surfaces, the SIMIR has a noise level approaching 1 x 10(-4) absorbance units, which is sufficient for detecting nanometer thick organic film residues on metals. The use of this nondestructive inspection tool is demonstrated by the spatial mapping of organic stains on sand blasted metals in which organic stains such as silicone oils, mineral oils, and triglycerides are identified both qualitatively and quantitatively over the surface of the metal specimen.

This work focused on the development of high internal phase emulsion (HIPE) polymerized foams with thermal and mechanical performance designed for use in composite processes. In contrast to typical blown foam systems, HIPE foams were investigated in order to take advantage of their unique combination of processing and property benefits. Thermal properties of typical styrene/divinylbenzene HIPE foams were dramatically improved by copolymerizing styrene with N-cyclohexylmaleimide and bismaleimide monomers in a HIPE process. This process produced polymeric, structural foams with glass transition temperatures ranging from 130 - 220 degrees C (265 - 425 degrees F) and compression strengths of 550 - 700 kPa (80 - 100 psi) at foam densities under 80 mg/cm(3) (5.0 lb/ft(3)).

Thus, there is a need within the remote and teleoperated robotic field for better man-machine interfaces. Telepresence attempts to bring real world senses to the operator, especially where the scale and orientation of the robot is so different from the scale of a human operator. This paper will report on research performed at the INEL which identified and evaluated current developments in telepresence best suited for nuclear applications by surveying of national laboratories, universities, and evaluation of commercial products available in industry. The resulting telepresence system, VirtualwindoW, attempts to minimize the complexity of robot controls and to give the operator the ''feel'' of the environment without actually contacting items in the environment. The authors of this report recommend that a prolonged use study be conducted on the VirtualwindoW to determine and bench mark the length of time users can be safely exposed to this technology In addition, it is proposed that a stand alone system be developed which combines the existing multi-computer platform into a single processor telepresence platform. The stand alone system would provide a standard camera interface and allow the VirtualwindoW to be ported to other telerobotic systems.

(1987) Mutat. Res., 176:267-274; Rutledge and Generoso, (1989) Teratology, 39:563-572]. The present study was designed to determine whether EtO also affects the skeletal system. We report here the effects of varying times of exposure during the zygotic period on skeletal development. Female hybrid mice were injected intraperitoneally (IF) with 125 mg/kg EtO at 1, 3, 5, or 7 hr postmating. A positive control group consisted of female mice that were injected IP with 150 mg/kg EtO once daily between the 6th to 8th days of gestation. Day 17 fetuses were double-stained for ''blind'' examination of skeletal deviations and degree of ossification. Zygotic exposure to EtO significantly increased loss of conceptuses as well as the incidence of external defects, skeletal anomalies, and retarded ossification in live day 17 fetuses. An increase in the number of exposed fetuses with cleft sternum was observed with the highest rate (58.5%) occurring in fetuses whose mothers were exposed to EtO 3 hours postmating. Cleft sternum was seen in only 5% of fetuses exposed during the period of organogenesis and less than 1% of control fetuses. It is concluded that zygotic exposure to EtO produces a pattern of skeletal defects that differs from those observed following treatment with EtO during organogenesis.

In its simplest form and applied to incompressible flow, the model depends on five phenomenological constants defining the strength of turbulence coupling to mean flow, turbulence transport in physical and wave-number space, and mixing of stress-tenser components. The implications for homogeneous isotropic turbulence are investigated in detail and found to correspond well to the conclusions from more fundamental theories. Under appropriate limiting conditions, a turbulent system described by the model will relax over time into a state of approximate spectral equilibrium permitting a reduction to a ''one-point'' model for the system that is substantially like the familiar K-epsilon model. This yields preliminary estimates of the present model's parameters and points to the way to improved modeling of flows beyond the applicability of the K-epsilon method.

This report describes the individual components of the program and how MAVIS II is used with other available tools to integrate the design and understanding of explosive valves for spacecraft applications. The rationale and model used for each valve interaction is described. Comparisons of the calculated results with available data have demonstrated the feasibility and accuracy of using MAVIS II for analytical studies of explosive valve interactions. The model used for the explosive or pyrotechnic used as the driving force in explosive valves is the most critical to be understood and modeled. MAVIS II is an advanced version that incorporates a plastic, as well as elastic, modeling of the deformations experienced when plungers are forced into a bore. The inclusion of a plastic model has greatly expanded the use of MAVIS for all categories (opening, closure, or combined) of valves, especially for the closure valves in which the sealing operation requires the plastic deformation of either a plunger or bore over a relatively large area. In order to increase its effectiveness, the use of MAVIS II should be integrated with the results from available experimental hardware. Test hardware such as the Velocity Interferometer System for Any Reflector (VISAR) and Velocity Generator tests provide experimental data for accurate comparison of the actual valve functions. Variable Explosive Chamber (VEC) and Constant Explosive Volume (CEV) tests are used to provide the proper explosive equation-of-state for the MAVIS calculations of the explosive driving forces. The rationale and logistics of this integration is demonstrated through a recent example. A recent valve design is used to demonstrate how MAVIS II can be integrated with experimental tools to provide an understanding of the interactions in this valve.

Electrochemical aging of zinc anodes results in physical and chemical changes at the zinc-concrete interface. Concrete surfaces heated prior to thermal-spraying had initial adhesion strengths 80 pct higher than unheated surfaces. For electrochemical aging greater than 200 kC/m(2) (5.2 A-h/ft(2)), there was no difference in adhesion strengths for zinc on preheated and unheated concrete. Adhesion strengths decreased monotonically after about 400 to 600 kC/m(2) (10.4 to 15.6 A-h/ft(2)) as a result of the reaction zones at the zinc-concrete interface. A zone adjacent to the metallic zinc (and originally part of the zinc coating) was primarily zincite (ZnO), with minor constituents of wulfingite (Zn(OH)(2)), simonkolleite (Zn-5(OH)(8)Cl-2 . H2O), and hydrated zinc hydroxide sulfates (Zn4SO4(OH)(6) . xH(2)O). This zone is the locus for cohesive fracture when the zinc coating separates from the concrete during adhesion tests. Zinc ions substitute for calcium in the cement paste adjacent to the coating as the result of secondary mineralization.

Thermally sprayed polymer coatings are of interest to several industries for anti-corrosion applications, including the infrastructural, chemical, automotive, and aircraft industries. Classical experiments were conducted, from which a substantial range of thermal processing conditions and their effect on the resultant coating were obtained. The coatings were characterized and evaluated by a number of techniques, including Knoop microhardness tests, optical metallography, image analysis, and bond strength. Characterization of the coatings yielded thickness, bond strength, hardness, and porosity. RP Varacalle, DJ (reprint author), IDAHO NATL ENGN LAB,IDAHO FALLS,ID 83415, USA.

There are conflicting reports in the literature about the extent of injection-induced particle-sizing effects in air plasma-sprayed materials. If significant spatial separation of finer and coarser particles in the jet occurs, then one would expect it to play an important role in determining the microstructure and properties of deposits made from powders containing a wide range of particle sizes. This paper presents the results of a study in which a commercially available zirconia powder was fractionated into fine, medium, and coarse cuts and sprayed at the same torch conditions used for the ensemble powder. Diagnostic measurements of particle surface temperature, velocity, and number-density distributions in the plume for each size-cut and for the ensemble powder are reported. Deposits produced by traversing the torch back and forth to produce a raised bead were examined metallographically to study their shape and location with respect to the torch centerline and to look at their internal microstructure. The results show that, for the torch conditions used in this study, the fine, medium, and coarse size-cuts all followed the same mean trajectory. No measurable particle segregation effects were observed. Considerable differences in coating microstructure were observed. These differences can be explained by the different particle properties measured in the plume. RP Neiser, RA (reprint author), SANDIA NATL LABS,POB 5800,ALBUQUERQUE,NM 87185, USA.

It was found that a loss of Al during spraying results from the extremely low thermal conductivity of the quasicrystalline phase in the starting powders. This loss changes the bulk composition of the deposited coating and partially controls the phases that develop. Smaller starting powder particles tended to lose more Al and, therefore, form less of the quasicrystalline phase. Larger starting powder particles did not lose Al to the same degree, and produced coatings with more of the quasicrystalline phase. However, these powders produced coatings also had a higher amount of porosity. RP Sordelet, D (reprint author), IOWA STATE UNIV SCI & TECHNOL,AMES LAB,AMES,IA 50011, USA.

However, the lower silicides such as Mo5Si3 do not provide such resistance. In this study, atmosphereic plasma sprayed (APS) MoSi2 particle temperatures and velocities were measured under various torch conditions chosen to span the majority of typically utilized spray parameters. Empirical models of particle temperature and velocity were computed from the data. Three spray conditions were chosen to produce high, medium and low particle temperatures and velocities. Coatings produced under these spray conditions were characterized by profile tracing, quantitative x-ray diffraction, and SEM analysis. The Mo5Si3 level in the coatings ranged from 5% to 8% while the Mo5Si3 level in the starting powder was 0.6%. Particle size, particle trajectory, and torch parameters were found to be important factors in the Si loss process when APS depositing MoSi2.

The fraction of unmelted particles is also found to increase with increasing velocity at the lower temperature. The relative deposition efficiency is approximately twice as high for the lower temperature particles compared to the high temperature, and for both temperatures the deposition efficiency decreases substantially with increasing velocity.

Three-dimensional Computational Fluid Dynamics (CFD) results are presented for a curved aircap used for coating interior surfaces such as engine cylinder bores. The device analyzed is similar to the Metco Diamond Jet Rotating Wire (DJRW) torch. The feed gases are injected through an axisymmetric nozzle into the curved aircap. Premixed propylene and oxygen are introduced from an annulus in the nozzle, while cooling air is injected between the nozzle and the interior wall of the aircap. The combustion process is modeled using a single-step finite-rate chemistry model with a total of 9 gas species which includes dissociation of combustion products. A continually-fed steel wire passes through the center of the nozzle and melting occurs at a conical tip near the exit of the aircap. Wire melting is simulated computationally by injecting liquid steel particles into the flow field near the tip of the wire. Experimental particle velocity measurements during wire feed were also taken using a Laser Two-Focus (L2F) velocimeter system. Flow fields inside and outside the aircap are presented and particle velocity predictions are compared with experimental measurements outside of the aircap.

Stainless steel particle velocity, temperature, size and relative number are measured for a high power plasma spray system operating at 110 kW. At the same torch operating conditions the plasma and particle now fields are simulated with a newly developed computational model. It was found that the injection geometry plays an important role in the particle entrainment, heating and acceleration. In spite of the complexity of the system, i.e. supersonic plasma velocity with a high swirl component, the simulation produced reasonalble particle trajectories resulting in good agreement between the calculated and measured particle velocity, temperature and size distributions.

In this study, the effect of the initial substrate temperature on the resulting thermal diffusivity of the beryllium coatings and the thermal diffusivity at the coating/beryllium substrate interface (i.e. interface thermal resistance) was investigated. Results have shown that initial beryllium substrate temperatures greater than 600 degrees C can improve the thermal diffusivity of the beryllium coatings and minimize any thermal resistance at the interface between the beryllium coating and beryllium substrate.

High purity (>99.5 wt% pure Al2O3) alumina powders were plasma-sprayed on stainless steel substrates over a range of power levels, using two gun configurations designed to attain different spray velocities. Key electrical properties were measured to evaluate the resultant coatings as potential insulating materials for electrostatic chucks (ESCs) being developed for semiconductor manufacturing. Electrical resistivity of all coatings was measured under vacuum upon heating and cooling over a temperature range of 20 to 600 degrees C. Dielectric constants were also measured under the same test conditions. X-ray diffraction was performed to examine phase formation in the coatings. Results show the importance of powder composition and careful selection and control of spray conditions for optimizing electrical behavior in plasma-sprayed aluminum oxide, and point to the need for further studies to characterize the relationship between high temperature electrical properties, measured plasma-spray variables, and specific microstructural and compositional coating features.

The early use of steel compositions containing carbon contents above the eutectoid level is found in ancient weapons from around the world. For example, both Damascus and Japanese sword steels are hypereutectoid steels. Their manufacture and processing is of interest in understanding the role of carbon content in the development of modern steels. Although sporadic examples of UHCS compositions are found in steels examined in the early part of this century, it was not until the mid-1970s that the modern study began. This study had its origin in the development of superplastic behavior in steels and the recognition that increasing the carbon content was of importance in developing that property. The compositions that were optimal for superplasticity involved the development of steels that contained higher carbon contents than conventional modern steels. It was discovered, however, that the room temperature properties of these compositions were of interest in their own right. Following this discovery, a period of intense work began on understanding their manufacture, processing, and properties for both superplastic forming and room temperature applications. The development of superplastic cast irons and iron carbides, as well as those of laminated composites containing UHCS, was an important part of this history.

A ductile cast iron containing 3.6% C, 2.6% Si and 0.045% Mg was continuously hot-and-warm rolled or one-step press-forged from a temperature in the austenite range (900 degrees C-1100 degrees C) to a temperature below the A, temperature. Various amounts of reduction were used (from 60% to more than 90%) followed by a short heat treatment at 600 degrees C. The heat treatment lead to a structure of fine graphite in a matrix of ferrite and carbides. The hot-and-warm worked materials developed a pearlitic microstructure while the press-forged material developed a spheroidite-like carbide microstructure in the matrix. Cementite-denuded ferrite zones were developed around graphite stringers in the hot-and-warm worked materials, but such zones were absent in the press-forged material. Tensile properties including tensile strength and total elongation were measured along the direction parallel and transverse to the rolling direction and along the direction transverse to the press-forging direction. The tensile ductility and strength both increased with a decrease in the amount of hot-and-warm working, The press-forged materials showed higher strength (645 MPa) than the hot-and-warm worked materials (575 MPa) when compared at the same ductility level (22% elongation).

These high strengths result from the mechanical work introduced during wire and rod processing. These strengths have been observed to increase with carbon content. In wire form, tensile strengths approaching 6000 MPa are predicted for UHCS containing 1.8%C. In this paper we will discuss the influence of processing (including rapid transformation during wire patenting) and microstructure on the mechanical behavior of UHCS wire. The tensile properties of as-extruded rods are described as a function of extrusion temperature and composition. For spheroidized steels, yield and ultimate tensile strength are a function of grain size, interparticle spacing and particle size. For pearlitic steels, yield and ultimate strength were found to be functions of colony size, carbide size and plate spacing and orientation. Alloying additions (such as C, Cr, Si, Al and Co) can influence the effect of processing on these microstructural features. For spheroidized steels, fracture was found to be a function of the size of coarse carbides and of composition. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94551 USA.

Design criteria are examined and reveal that only grid design modifications are required. In the special case where cell width dimensions are 4-5 cm, an interdigitated design removes the back contact as a loss mechanism. Processing issues relating to the intrinsic ZnO layer are critical to optimal and reproducible cell performance. 1-sun and 20 sun performance of 17.7% are reported for different cells. The latter represents a 2.9% absolute improvement over the 1-sun control measurement. 20% performance is therefore a realistic goal. CIGS-based cells represent a viable concentrator technology.

We observed considerable variation in the EBIC peak position, the uniformity (between and within devices), and overall charge-collection profile of the junction as a function of Ga concentration. Whereas using only CuInSe2 (CIS) absorber material results in a rather wide and buried junction in the CIS, the systematic addition of Ga to the p-CuInSe2 matrix affects the conductivity type of the material, thereby creating an increasingly abrupt uniform, and shallow junction near the heteroface. Although the substitution of Ga for In improves overall device performance up to similar to X = 25% and the V-OC continues to improve, the J(SC), FF, and device efficiency degrade with additional Ga.

Because of surface preparation problems, high process temperatures, and mismatch of thermal expansion coefficients, adhesion of the Mo to the soda lime glass can be variable. Also beneficial is the Na facile diffusion of the glass into the absorber layer. We report on the use of thin Cr interlayers to improve the adhesion at the Mo/glass interface. The films were subsequently annealed in vacuum under normal process conditions. Adhesion was excellent and quite uniform for Mo layers with a Cr interlayer of 50 to 800 Angstrom compared to control samples without Cr. X-ray Photoelectron Spectroscopy (XPS) data suggests CrO bonding at the glass interface and Cr metallic bonding at the Cr Mo interface. Secondary Ion Mass Spectrometry (SIMS) data for Mo/Cr films shows diffusion of Na throughout the Mo layer identical to that for Mo alone samples. Resistivities of the films have been measured to be 11 mu ohms-cm, twice that for bulk material of 5.7 mu ohms-cm. CIGS films were then grown for comparison to films grown on Mo only substrates.

Kinetics and overall yield experiments were performed over the temperature range, 946-2046 K, using the atomic resonance absorption spectrometric technique (ARAS) for the temporal detection of both product H and I atoms behind reflected shock waves. The C2H5I decomposition proceeds by both C-I fission and HI elimination. Rate constants for the C-I fission process, measured ol-er the temperature and density ranges, 946-1303 K and 0.82-4.4 x 10(18) cm(-3), respectively can be represented to within +/- 37% by the first-order expression: k = 6.34 x 10(9) exp(- 15,894 WT) s(-1). Overall yield data for atomic product gave a branching ratio for C-I fission of (0.87 +/- 0.11) suggesting that 13% of the reaction proceeds through molecular HI elimination. This conclusion is consistent with earlier studies that showed C-I fission to be the dominant dissociation channel. The temperature and pressure dependences of the dissociation rate constants and the yield data have been described theoretically using three formulations of unimolecular rate theory. The best description was obtained with a full Master's equation analysis. However all three calculations confirm that the HI-elimination pathway is lower lying than the C-I fission process by similar to 3 kcal mol(-1). C1 Argonne Natl Lab, Div Chem, Argonne, IL 60439 USA.

Small amounts of neopentane were added to slowly reacting mixtures of H-2 + O-2 + N-2 A complete analysis of all products, except H2O and peroxide, was carried out for three mixtures containing 5 torr neopentane: (1) the standard mixture (H-2 = 140, O-2 = 10, N-2 = 285 torr); (2) one of high O-2 content (H-2 = 140, O-2 = 355 torr); and (3) one of high H-2 content (H-2 = 425, O-2 = 70 torr). Experimental results for mixtures 2 and 3 have appeared in prior publications, but the results for mixture 1, although obtained at the same time, have not previously been reported. Analysis showed that the primary products formed in the experiments included isobutene, 3,3-dimethyloxetan, acetone, methane, and formaldehyde. The major secondary products were 2,2-dimethyloxiran, propene, isobuteraldehyde, methacrolein, and 2-methylprop-2-en-1-ol. A detailed kinetic model was used to explain both primary and secondary product formation. Because the experiments were carried out at 753 EC, both low- and high-temperature reaction schemes are important and resulted in a model comprising 310 species and 1570 elementary reactions. This model was able to explain both primary and secondary product formation with a high degree of accuracy: almost all secondary product formation could be explained through the formation of isobutene. In agreement with past kinetic studies, the addition reaction of neopentyl radical with molecular oxygen and the alkylperoxy radical isomerization reaction were found to be ver important. In addition, the importance of the reverse isomerization, from hydroperoxy-neopentyl to neopentylperoxy radical, was established. C1 Univ Calif Lawrence Livermore Natl Lab, Livermore, CA 94550 USA.

In particular we have determined the elementary reaction steps in the conversion of two cyclopentadienyl radicals to naphthalene. This reaction mechanism is shown to be an extension of the mechanism occurring in the H atom-assisted conversion of fulvene to benzene. The net reaction involves die formation of dihydrofulvalene, which eliminates a hydrogen atom and then rearranges to form naphthalene through a series of ring closures and openings. The importance of forming the -CR(.)-CHR-CR' = CR "- moiety, which can undergo rearrangement to form three-carbon atom ring structures, is illustrated with the C4H7 system. The ability of hydrogen atoms to migrate around the cyclopentadienyl moiety is illustrated both for methyl-cyclopentadiene, C5H5CH3, and dihydrofulvalene, C5H5C5H5, as well as for their radical species, C6H7 and C5H5C5H4. The mobility of hydrogen in the cyclopentadienyl moiety plays an important role both in providing resonance-stabilized radical products and in creating the -CR(.) CHR-CR' = CR "- moiety for ring formation. The results illustrate the radical pathway for concerting five-membered rings to aromatic six-membered rings. Furthermore, the results indicate the important catalytic role of H atoms in the aromatic ring formation process. C1 Sandia Natl Labs, Livermore, CA 94551 USA.

The mutually annihilating dames initially accelerate before quenching as observed by other studies involving reduced chemistry. The mechanism of dris acceleration is investigated by comparing the balance between transport and reaction of O-2 at different times. The primary contribution to the enhanced flame propagation is attributed to a change in the balance between reaction and diffusion. This effect is further enhanced by a decrease in the concentration gradients of the reactants during diffusional interactions of the mutually annihilating flames. The rates of fuel consumption and oxidation of H-2 and CO are significantly enhanced before the merging of the various consumption/oxidation layers. The diffusion of He from the reaction zone to the unburned reactants is reversed, resulting in a buildup of H-2 concentration in the reaction zone. H-2 plays a key role in enhancing the chemistry before the merging of the various consumption layers because of its high mass diffusivity and its importance in the production of radicals. In particular, the accumulation of H-2 in the reaction zone results in the enhancement of reactions that produce H from the H-2/O-2 system and in a buildup of radicals including H, O, and OH. The increased contribution of the H-2/O-2 system continues until the onset of quenching of the H-2 oxidation layer. CO oxidation then becomes the dominant contribution to H-radical production. During the flame deceleration phase, H-radical production is significantly reduced. The key reactions governing the production of radicals shift from the fuel (HCO and CH3) to H-2 and CO oxidation. Radical recombination reactions, which play a key role in flame-wall quenching, are insignificant until all fuel and H-2/CO oxidation layers are quenched.

Coherent anti-Stokes-Raman spectroscopy (CARS) of N-2 was performed to obtain temperature profiles. The dependence of the DFWM signal on temperature was shown theoretically to be reduced by the short predissociative lifetimes of the CH3 upper states. A two-color DFWM mixing experiment indicated that DFWM from CH3 in CH4 flames was predominately the result of population gratings. Using population-grating theory, the DFWM signal profile was corrected for varying temperature, beam absorption, and lower-state lifetimes. The results were in reasonable agreement with flame calculations and demonstrate chat DFWM can provide useful relative concentration profiles of a polyatomic radical in rich hydrocarbon flames. However, we found that a weak DFWM background signal limited detection sensitivity to approximate to 70 ppm of CH3 in CH4 flames. The background was comparable to the CH3 signal in C3H8 flames, and it obscured the CH3 signal in rich C2H2 and C2H4 flames. Strategies to alleviate the background are discussed.

A global two-step reaction mechanism applicable to certain types of degraded nitramine propellants and consisting of sequential condensed and gaseous steps, is postulated. Taking into account important effects due to multiphase flow and exploiting the limit of large activation energies, a theoretical analysis based on activation-energy asymptotics leads to explicit formulas for the deflagration velocity in a specifically identified regime that is consistent dth the merged-flame assumption. The results clearly indicate the influences of two-phase flow and the multiphase, multi-step chemistry on the deflagration structure and the burning rate, and define conditions that support the intrusion of the primary gas flame into the two-phase condensed decomposition region at the propellant surface.

The experiments were performed at pressures from 1 to 10 bar and temperatures ranging from 925 to 1375 K. The inlet O-2 level was varied from 1000 ppm to 10%, while NH3 and NO were maintained at 1000 and 500 ppm, respectively At the highest pressure, CO was added to shift the regime for NO reduction to lower temperatures. The results show that the pressure affects the location and the width of the temperature window for NO reduction. As the pressure is increased, both the lower and the higher boundaries for the process are shifted toward higher temperatures. Overall, the temperature range for NO reduction appears to be slightly broadened. The shift in chemistry toward higher temperatures is mast pronounced at low oxygen concentrations. High oxygen levels act to counterbalance the inhibiting effect of the pressure but also cause a slight decrease in the NO reduction potential. The results are consistent with recent atmospheric pressure experiments of thermal de-NOx covering a wide range of reactant partial pressures. Comparisons of the experimental data with the recent chemical kinetic model of Miller and Glarborg show satisfactory agreement. The implications of the results for application of thermal de-NOx in high-pressure systems, such as pressurized fluidized bed combustion and gas turbines, are discussed.

This is accomplished without direct measurement of O atoms by laser-induced fluorescence, a technique that has been shown to be problematic. Simultaneous point measurements of temperature, the major species, OH, and NO are performed in a non-premixed turbulent jet flame of nitrogen-diluted hydrogen fuel. The O-atom concentration for each laser shot is derived from these data, based on the assumption of partial equilibrium of the reaction OH + OH = O + H2O. The derived O-atom concentration is then used with the measured N-2 concentration and temperature to calculate the instantaneous thermal (Zeldovich) NO production rate. The partial equilibrium assumption is shown to be appropriate in this flame for conditions relevant to thermal NO formation. The maximum conditionally averaged O-atom mole fraction is about 6.5 times the maximum value for full chemical equilibrium. The width in mixture fraction coordinates of the conditionally averaged NO production rate curve is roughly twice that calculated from adiabatic equilibrium values of temperature, [O], and N-2. Experimental results are compared with predictions obtained using the Monte Carlo PDF model with detailed chemistry. With some exceptions, there is good agreement between experiment and prediction when results are plotted against mixture fraction (scatter plots and conditional averages). Agreement is not as good when radial profiles of averaged scalar quantities are compared. This indicates that the present PDF model predicts the hydrogen and nitrogen chemistry with good accuracy but that improvements are needed in the modeling of the turbulent fluid dynamics and mixing. A comparison of experimental results with steady strained laminar flame calculations shows that the turbulent flame conditions cannot be represented by a combination of the laminar flames.

Computed and experimental results are compared and used Co help understand the chemical factors leading to engine knack in spark-ignited engines. The kinetic model reproduces observed Variations in critical compression ratio with fuel molecular size and structure, provides intermediate product species concentrations in good agreement with observations, and gives insights into the kinetic origins of fuel octane sensitivity Sequential computed engine cycles were found to lead to stable, nonigniting behavior for conditions below a critical compression ratio; to unstable, oscillating, but nonigniting behavior in a transition region; and eventually to ignition as the compression ratio is steadily increased. This transition is related to conditions where a negative temperature coefficient of reaction exists, which has a significant influence on octane number and fuel octane sensitivity. Improvements in the detailed kinetic reaction mechanism include better treatments of dihydroperoxide radical species and more accurate thermochemical quantities, which lead to better reverse reaction rate expressions.

The experiments were carried out in a 27-cm-inner diameter, 21.3-meter-long heated detonation tube, which was equipped with periodic orifice plates to promote flame acceleration. Hydrogen-air-steam mixtures were tested at a range of temperatures up to 650 K and at an initial pressure of 0.1 MPa. In most cases, the limiting hydrogen mole fraction that resulted in transition to detonation corresponded to the mixture whose detonation cell size, I, was approximately equal to the inner diameter of the orifice plate, d (e.g., d/lambda = 1). The only exception was in dry hydrogen-air mixtures at 650 K where the DDT limit was observed to be 11% hydrogen, corresponding to a value of d/lambda equal to 5.5. For a 10.5% hydrogen mixture at 650 K, the dame accelerated to a maximum velocity of about 120 m/s and then decelerated to less than 2 m/s. This observation indicates that the d/lambda. = DDT limit criterion provides a necessary condition but not a sufficient one for the onset of DDT in obstacle-laden ducts. In this particular case, the initial mixture condition (i.e., temperature) resulted in the inability of the mixture to sustain dame acceleration to the point at which DDT could occur. It was also observed;hat the distance required for the flame to accelerate to the onset of detonation was a function of both the hydrogen mole fraction and the initial mixture temperature. For example, decreasing the hydrogen mole fraction or increasing the initial mixture temperature resulted in longer transition distances.

Application is not limited to periodic, or even to planar interfaces. Characteristic structural units can be extracted from an experimental image and some important parameters such as mirror or mirror glide symmetry, and rigid body displacements can be determined without knowledge of the imaging parameters. The technique allows an image of a structural unit with reduced specimen noise to be obtained by averaging over several similar units, even if a boundary is not periodic and not planar.
