Coal gasification via the Lurgi process: Topical report: Volume 1, Production of SNG (substitute material gas)  

Science Conference Proceedings (OSTI)

A Lurgi baseline study was requested by the DOE/GRI Operating Committee of the Joint Coal Gasification Program for the purpose of updating the economics of earlier Lurgi coal gasification plant studies for the production of substitute natural gas (SNG) based on commercially advanced technologies. The current study incorporates the recent experience with large size Lurgi plants in an effort to improve capital and operating costs of earlier plant designs. The present coal gasification study is based on a mine mouth plant producing 250 billion Btu (HHV) per day of SNG using the Lurgi dry bottom coal gasification technology. A Western subbituminous coal was designated as the plant food, obtained from the Rosebud seam at Colstrip, Montana. This study presents the detailed description of an integrated facility which utilizes coal, air, and water to produce 250 billion Btu (HHV) per day of SNG. The plant consists of coal handling and preparation, twenty-six Lurgi dry bottom gasifiers, shift conversion, acid gas removal, methanation, compression and drying of product gas, sulfur recovery, phenol and ammonia recovery, as well as necessary support facilities. The plant is a grass roots, mine mouth facility located in a Western location similar to the town of Colstrip in Rosebud County, Montana. The Lurgi Corporation assisted in this study, under subcontract to Foster Wheeler, by supplying the heat and material balances, flow sheets, utilities, catalysts and chemical requirements, and cost data for Lurgi designed process sections. Details of material supplied by Lurgi Corporation are presented in Appendix A. 52 refs., 36 figs., 64 tabs.

Reactor materials study of EBR-II and BN350  

E-Print Network (OSTI)

The objective of this research is to go through the technical review of how the body of information relating to the in-reactor behavior of structural materials of Experimental Breeder Reactor-II (EBR-II) and BN350 are associated. Such an effort would lead to reviewing and combining the data from both sides as it concerns important issues for the Light Water Reactor (LWR) and fast reactor communities. The most important issue is the applicability of the BN350 and EBR-II data for the studies on prolonging the lifetime of LWRs. EBR-II and BN350 are sodium cooled fast reactors that had operated for more than twenty-five years. Studies to review and compile the existing reactor materials data for the purpose of this thesis were completed both in the U.S. and in Kazakhstan. The compilation, comparison and combination of the data was done by developing several databases using SQL software. The BN350 data on ultimate tensile strength and total elongation depending on swelling have been shown. The BN350 data is over a large swelling range (0-15 %) and reveals total consumption of ductility and strength as the amount of swelling reaches high values. The BN350 data is an important example supporting other studies that show a dominant correlation between swelling and mechanical property loss in the high swelling range (>10 %). Different forms of axial strain data from both reactors, which could be of use in reactor control and decommissioning studies, are presented, as well. The swelling formulations developed for Russian and American austenitic steels before reaching steady-state conditions are compared, and possible applications of the formulation for Russian steels to some compositionally similar American steels have been discussed. The effects of slight composition and metallurgical condition differences on swelling are stated to explain the possible differences between the data points of American steel and the predictions for the corresponding Russian steel. Some of the compiled data on ferritic/martensitic steels are presented showing their better mechanical property and swelling behaviors in the EBR-II and BN350 exposure conditions.

Solvent substitution  

Science Conference Proceedings (OSTI)

The DOE Environmental Restoration and Waste Management Office of Technology Development and the Air Force Engineering and Services Center convened the First Annual International Workshop on Solvent Substitution on December 4--7, 1990. The primary objectives of this joint effort were to share information and ideas among attendees in order to enhance the development and implementation of required new technologies for the elimination of pollutants associated with industrial use of hazardous and toxic solvents; and to aid in accelerating collaborative efforts and technology transfer between government and industry for solvent substitution. There were workshop sessions focusing on Alternative Technologies, Alternative Solvents, Recovery/Recycling, Low VOC Materials and Treatment for Environmentally Safe Disposal. The 35 invited papers presented covered a wide range of solvent substitution activities including: hardware and weapons production and maintenance, paint stripping, coating applications, printed circuit boards, metal cleaning, metal finishing, manufacturing, compliance monitoring and process control monitoring. This publication includes the majority of these presentations. In addition, in order to further facilitate information exchange and technology transfer, the US Air Force and DOE solicited additional papers under a general Call for Papers.'' These papers, which underwent review and final selection by a peer review committee, are also included in this combined Proceedings/Compendium. For those involved in handling, using or managing hazardous and toxic solvents, this document should prove to be a valuable resource, providing the most up-to-date information on current technologies and practices in solvent substitution. Individual papers are abstracted separated.

Stability and Rate Capability of Al Substituted Lithium-Rich High-Manganese Content Oxide Materials for Li-Ion Batteries  

SciTech Connect

The structures, electrochemical properties and thermal stability of Al-substituted lithium-excess oxides, Li{sub 1.2}Ni{sub 0.16} Mn{sub 0.56}Co{sub 0.08-y}Al{sub y}O{sub 2} (y = 0, 0.024, 0.048, 0.08), are reported, and compared to the stoichiometric compounds, LiNi{sub z}Mn{sub z}Co{sub 1-2z}O{sub 2}. A solid solution was found up to at least y = 0.06. Aluminum substitution improves the poor thermal stability while preserving the high energy density of lithium-excess oxides. However, these high manganese compositions are inferior to the lithium stoichiometric materials, LiNi{sub z}Mn{sub z}Co{sub 1-2z}O{sub 2} (z = 0.333, 0.4), in terms of both power and thermal stability.

Novel Solar Energy Conversion Materials by Design of Mn(II) Oxides  

Science Conference Proceedings (OSTI)

Solar energy conversion materials need to fulfill simultaneously a number of requirements in regard of their band-structure, optical properties, carrier transport, and doping. Despite their desirable chemical properties, e.g., for photo-electrocatalysis, transition-metal oxides usually do not have desirable semiconducting properties. Instead, oxides with open cation d-shells are typically Mott or charge-transfer insulators with notoriously poor transport properties, resulting from large effective electron/hole masses or from carrier self-trapping. Based on the notion that the electronic structure features (p-d interaction) supporting the p-type conductivity in d10 oxides like Cu2O and CuAlO2 occurs in a similar fashion also in the d5 (high-spin) oxides, we recently studied theoretically the band-structure and transport properties of the prototypical binary d5 oxides MnO and Fe2O3 [PRB 85, 201202(R)]. We found that MnO tends to self-trap holes by forming Mn+III, whereas Fe2O3 self-traps electrons by forming Fe+II. However, the self-trapping of holes is suppressed by when Mn is tetrahedrally coordinated, which suggests specific routes to design novel solar conversion materials by considering ternary Mn(II) oxides or oxide alloys. We are presenting theory, synthesis, and initial characterization for these novel energy materials.

The EBR-II materials-surveillance program. 4: Results of SURV-4 and SURV-6  

SciTech Connect

In March of 1965, a set of surveillance (SURV) samples was placed in the EBR-II reactor to determine the effect of irradiation, thermal aging, and sodium corrosion on reactor materials. Eight subassemblies were placed into row 12 positions of EBR-II to determine the effect of irradiation at 370 C. Two subassemblies were placed into the primary sodium basket to determine the effect of thermal aging at 370 C. For both the irradiated and thermally aged samples, one half of all samples were exposed to primary system sodium while one half were sealed in capsules with a helium atmosphere. Fifteen different structural materials were tested in the SURV program. In addition to the fifteen types of metal samples, graphite blocks were irradiated in the SURV subassemblies to determine the effect of irradiation on the graphite neutron shield. In this report, the properties of these materials irradiated at 370 C to a total fluence of 2.2 x 10{sup 22} n/cm{sup 2} (over 2,994 days) are compared with those of similar specimens thermally aged at 370 C for 2,994 days in the storage basket of the reactor. The properties analyzed were weight, density, microstructure, hardness, tensile and yield strength, impact strength, and creep.

In March of 1965, a set of surveillance (SURV) samples was placed in the EBR-II reactor to determine the effect of irradiation, thermal aging, and sodium corrosion on reactor materials. Eight subassemblies were placed into row 12 positions of EBR-II to determine the effect of irradiation at 370 C. Two subassemblies were placed into the primary sodium basket to determine the effect of thermal aging at 370 C. One half of all samples were exposed to primary system sodium while one half were sealed in capsules with a helium atmosphere. Fifteen different structural materials were tested in the SURV program. In this work, the properties of these materials irradiated at 370 C to a total fluence of 3.2 {times} 10{sup 22} n/cm{sup 2} were determined. These materials are the fifth set of irradiated subassemblies to be examined as part of the SURV program (SURV-5). The properties analyzed were weight, density, microstructure, hardness, tensile and yield strength, and fracture resistance. Of all the alloys examined in SURV-5, only Berylco-25 showed any significant weight loss. Stainless steel (both 304 and 347) had the largest density decrease, although the density decrease from irradiation for all alloys was less than 0.4 percent. The microstructure of both Berylco-25 and the aluminum-bronze alloy was altered significantly. Iron- and nickel-base alloys showed little change in microstructure. Austenitic steels (304 and 347) harden with irradiation. The hardness of Inconel X750 did not change significantly with irradiation. The ultimate tensile strength of Inconel X750, 304 stainless steel, 420 stainless steel and welded 304 changed little due to a fluence increase from 2.2 {times} 10{sup 22} n/cm{sup 2} (the maximum fluence of the SURV-4 samples) to 3.2 {times} 10{sup 22} n/cm{sup 2}.

Structure and stability of Co(II)-complexes formed by wild-type and metal-ligand substitution mutants of T4 gene 32 protein  

E-Print Network (OSTI)

Phage T4 gene 32 protein (gp32) is a zinc metalloprotein that binds cooperatively and preferentially to single-stranded nucleic acids and functions as a replication and recombination accessory protein. We have previously shown that the ZN(II) coordination by gp32 employs a metal ligand donor set unrelated to any known zinc-finger motif thus far described and is derived from the His64-XI2-Cys77-Xg-Cys87-X2-CYS90 sequence in the ssDNA-binding core domain of the molecule. Crystallographic studies reveal that His64 and Cys77 are derived from two independent p-strands and are relatively more buried from solvent than are Cys87 and Cys9O, which combine to nucleate an (X-helix. In an effort to understand the origin of the stability of the metal complex, we have employed an anaerobic optical spectroscopic, competitive metal binding assay to determine the coordination geometry and association constants (Ka) for the binding of CO(II) to wild-type gp32 and a series of zinc ligand substitution mutants. We find that all non-native metal complexes retain tetrahedral coordination geometry but are greatly destabilized in a manner essentially independent of whether a new protein-derived coordination bond is forfned (e.g., in H64C gp32) or not. Quantitative Co(H) binding isotherms for the His64 mutants reveal that these gp32s form a dimeric CYS4 tetrathiolate intermediate complex of differing affinities at limiting [Co]f; each then rearranges at high [Co]f to form a monomolecular site of the expected geometry and Ka=IXIO4 M-1. C87S and C90A gp32s, in contrast, form a single complex at all [Co]f, consistent with CYS2-His-H20 tetrahedral geometry of Ka=1-2xlo5 M-1. The susceptibility of all mutant metal sites to oxidation by 02 is far greater than the wild-type protein; none appear to be functional ssDNA binding proteins. These studies reveal that the local protein structure greatly limits accommodation of an altered complex in a ligand-specific manner. The implications of this work for de novo design of zinc complexes in proteins will be discussed.

SNMSP II: A system to fully automate special nuclear materials accountability reporting for electric utilities  

SciTech Connect

The USNRC requires each licensee who is authorized to possess Special Nuclear Materials (SNM) to prepare and submit reports concerning SNM received, produced, possessed, transferred, consumed, disposed of, or lost. These SNM accountability reports, which need to be submitted twice a year, contain detailed information on the origin, quantity, and type of SNM for several locations. The amount of detail required makes these reports very time consuming and error prone when prepared manually. Yankee Atomic is developing an IBM PC-based computer code that fully automates the process of generating SNM accountability reports. The program, called SNMSP II, prints a number of summaries including facsimiles of the NRC/DOE-741, 742, 742C, and RW-859 reports in a format that can be submitted directly to the NRC/DOE. SNMSP II is menu-driven and is especially designed for people with little or no computer training. Input can be either from a mainframe-based corporate data base or manually through user-friendly screens. In addition, extensive quality assurance features are available to ensure the security and accuracy of the data. This paper discusses the major features of the code and describes its implementation at Yankee.

Evaluation of H2 Getter Materials for Use in the TRUPACT-II  

DOE Green Energy (OSTI)

Savannah River Site (SRS) has many waste drums containing Pu-238 that exceed the currently allowed wattage for transportation in the Transuranic Package Transporter-II (TRUPACT-II). By eliminating layers of confinement in waste drums and using getters to remove hydrogen gas, the TRUPACT-II waste loading can be increased significantly, with the potential of reaching the package''s 40-watt thermal limit. The cost savings associated with increasing the waste loading are enormous, and can be measured by reduced numbers of shipments, required processing facilities, and years of effort. To support the decision-making process and provide a good starting point for future development efforts at SRTC, the design requirements for a getter system to be used in the TRUPACT-II were compiled and are discussed in detail in the Appendix.

Electrode Materials with the Na0.44MnO2 Structure: Effect ofTitanium Substitution on Physical and Electrochemical Properties  

Science Conference Proceedings (OSTI)

The physical and electrochemical properties of LixMnO2 and LixTi0.11Mn0.89O2 synthesized from precursors made by glycine-nitrate combustion (GNC) and solid-state synthesis methods (SS) are examined in this paper. The highest specific capacities in lithium cells are obtained for SS-LixMnO2 electrodes at low current densities, but GNC-LixTi0.11Mn0.89O2 electrodes show the best high rate performance. These results can be explained by changes in the voltage characteristics and differences in the particle morphologies induced by the Ti-substitution and synthesis method. Ti-substitution also results in a decrease in the electronic conductivity, but greatly improves the thermal properties and imparts dissolution resistance to the electrode. For these reasons, it is preferable to use LixTi0.11MnO0.89O2 in lithium battery configurations rather than LixMnO2. Suggestions for improving the electrochemical performance of the Ti-substituted variant are given based on the results described herein.

INFORMATION: Inspection Report on "Removal of Categories I and II Special Nuclear Material from Sandia National Laboratories-New Mexico"  

Science Conference Proceedings (OSTI)

The Department of Energy's (DOE's) Sandia National Laboratories-New Mexico (Sandia) develops science-based technologies in support of national security in areas such as nuclear weapons, nonproliferation, military technologies, and homeland security. Sandia's primary mission is ensuring that the U.S. nuclear arsenal is safe, secure, and reliable and can fully support the Nation's deterrence policy. Part of this mission includes systems engineering of nuclear weapons; research, design, and development of non-nuclear components; manufacturing of non-nuclear weapons components; the provision of safety, security, and reliability assessments of stockpile weapons; and the conduct of high-explosives research and development and environmental testing. Sandia Corporation, a subsidiary of Lockheed Martin Corporation, operates Sandia for the National Nuclear Security Administration (NNSA). On May 7, 2004, the Secretary announced that the Department would evaluate missions at DOE sites to consolidate Special Nuclear Material (SNM) in the most secure environments possible. The Administrator of the NNSA said that this effort was a key part of an overall plan to transform the nuclear weapons complex into a smaller, safer, more secure, and more efficient national security enterprise. In February 2008, Sandia was the first site to report it had reduced its on-site inventory of nuclear material below 'Categories I and II' levels, which require the highest level of security to protect material such as plutonium and highly enriched uranium. The Office of Inspector General initiated an inspection to determine if Sandia made appropriate adjustments to its security posture in response to the removal of the Categories I and II SNM. We found that Sandia adjusted its security posture in response to the removal of Categories I and II SNM. For example, security posts were closed; unneeded protective force weapons and equipment were excessed from the site; and, Sandia's Site Safeguards and Security Plan was modified. We also found that some highly enriched uranium in a complex material configuration was not removed from Sandia. This material was designated as Category III material using a methodology for assessing the attractiveness of complex materials that was not specifically addressed in any current DOE directive. Although DOE and NNSA officials believed that this designation was appropriate, the methodology used to support this designation had not, as of the time of our review, been incorporated into the DOE directives system. Historically, the Department has considered the categorization of SNM to be an important national security and public policy issue. Consequently, we believe that expedited action should be taken to formalize this methodology in the DOE directives system and that it be disseminated throughout the Department of Energy complex.

Biomedical studies on solvent refined coal (SRC-II) liquefaction materials: a status report  

SciTech Connect

This technical report summarizes the results of biomedical research effort on solvent refined coal (SRC) materials. The samples, described in the text, as well as samples of raw shale oil, crude petroleum, and some SRC-I materials were evaluated for biological activity in several different systems: (1) microbial mutagenesis (Ames assay), coupled to chemical characterization efforts, (2) in vitro mammalian cell toxicity and transformation, (3) epidermal carcinogenesis (skin painting) in mice, (4) acute and subchronic oral toxicity in rats, (5) developmental toxicity in rats, and (6) dosimetry and metabolism in rats. High boiling point materials (identified) showed significant mutagenic activity while lower boiling fractions from both processes were inactive; crude petroleum was also inactive, while raw shale oil showed only a low level of activity. Chemical characterization studies suggested that 3- and 4-ring primary aromatic amines are responsible for a large fraction of the mutagenic activity. Cultured mammalian cell studies showed that materials exhibiting a positive effect in the Ames system also caused mammalian cell transformation. The results of skin carcinogenesis studies in the mouse were generally consistent with those of the cellular studies. Light distillates were found to be moderately toxic after oral administration to rats. Fuel upgrading, process modification, and appropriate occupational/environmental controls may ameliorate some of the biological effects of SRC materials and other coal liquids of high boiling point. Low-boiling SRC liquids appear to have little biological effects in the assays employed. (LTN)

Battery resource assessment. Subtask II. 5. Battery manufacturing capability recycling of battery materials. Draft final report  

SciTech Connect

Studies were conducted on the recycling of advanced battery system components for six different battery systems. These include: Nickel/Zinc, Nickel/Iron, Zinc/Chlorine, Zinc/Bromine, Sodium/Sulfur, and Lithium-Aluminum/Iron Sulfide. For each battery system, one or more processes has been developed which would permit recycling of the major or active materials. Each recycle process has been designed to produce a product material which can be used directly as a raw material by the battery manufacturer. Metal recoverabilities are in the range of 93 to 95% for all processes. In each case, capital and operating costs have been developed for a recycling plant which processes 100,000 electric vehicle batteries per year. These costs have been developed based on material and energy balances, equipment lists, factored installation costs, and manpower estimates. In general, there are no technological barriers for recycling in the Nickel/Zinc, Nickel/Iron, Zinc/Chlorine and Zinc/Bromine battery systems. The recycling processes are based on essentially conventional, demonstrate technology. The lead times required to build battery recycling plants based on these processes is comparable to that of any other new plant. The total elapsed time required from inception to plant operation is approximately 3 to 5 y. The recycling process for the sodium/sulfur and lithium-aluminum/sulfide battery systems are not based on conventional technology. In particular, mechanical systems for dismantling these batteries must be developed.

Numerical simulations of granular dynamics II. Particle dynamics in a shaken granular material  

E-Print Network (OSTI)

Surfaces of planets and small bodies of our Solar System are often covered by a layer of granular material that can range from a fine regolith to a gravel-like structure of varying depths. Therefore, the dynamics of granular materials are involved in many events occurring during planetary and small-body evolution thus contributing to their geological properties. We demonstrate that the new adaptation of the parallel N-body hard-sphere code pkdgrav has the capability to model accurately the key features of the collective motion of bidisperse granular materials in a dense regime as a result of shaking. As a stringent test of the numerical code we investigate the complex collective ordering and motion of granular material by direct comparison with laboratory experiments. We demonstrate that, as experimentally observed, the scale of the collective motion increases with increasing small-particle additive concentration. We then extend our investigations to assess how self-gravity and external gravity affect collective motion. In our reduced-gravity simulations both the gravitational conditions and the frequency of the vibrations roughly match the conditions on asteroids subjected to seismic shaking, though real regolith is likely to be much more heterogeneous and less ordered than in our idealised simulations. We also show that collective motion can occur in a granular material under a wide range of inter-particle gravity conditions and in the absence of an external gravitational field. These investigations demonstrate the great interest of being able to simulate conditions that are to relevant planetary science yet unreachable by Earth-based laboratory experiments.

Ignition Analysis of a Porous Energetic Material - II. Ignition at a Closed Heated End  

Science Conference Proceedings (OSTI)

A continuation of an ignition analysis for porous energetic materials subjected to a constant energy flux is presented. In the first part (I), the analysis was developed for the case of an open-end, semi-infinite material such that gas flow, generated by thermal expansion, flowed out of the porous solid, thereby removing energy from the system. In the present study, the case of a closed end is considered, and thus the thermally-induced gas flow is now directed into the solid. In these studies, an asymptotic perturbation analysis, based on the smallness of the gas-to-solid density ratio and the largeness of the activation energy, is utilized to describe the inert and transition stages leading to thermal runaway. In both cases it is found that the effects of porosity provide a leading-order reduction in the time to ignition relative to that for the nonporous problem, arising from the reduced amount of solid material that must be heated and the difference in thermal conductivities of the solid and gaseous phases. A correction to the leading-order ignition-delay time, however, is provided by the convective flow of gas through the solid, and the sign of this correction is shown to depend on the direction of the gas flow. Thus, gas flowing out of an open-end solid was previously shown to give a positive correction to the leading-order time to ignition. Here, however, it is demonstrated that when the flow of gas is directed into the porous solid, the relative transport effects associated with the gas flow serve to preheat the material, resulting in a negative correction and hence a decrease in the ignition-delay time.

MACHINING OF REFRACTORY MATERIALS. Phase II Technical Engineering Report, February 1, 1962 to April 30, 1962  

SciTech Connect

Machining studies were performed on pressed and sintered unalloyed tungsten, D-31 niobium alloy, 90Ta10W alloy, molybdenum TZM and Mo-0.5% Ti alloys, and a high temperature glass ceramic material. The investigation consisted of drilling and grinding tests on tungsten; turning, face milling, and grinding on D-31 niobium, turning, drilling, reaming, and tapping on 90Ta-10W alloy,; face milling, end milling, drilling, reaming, tapping, and grinding on molybdenum alloys; and grinding of the high temperature glass ceramic. A drill life of 27 holes was obtained on tungsten heated to 800 deg F using a 0.213 in. dia. solid carbide drill at 200 ft/min. In grinding, a G Ratio of 5.2 was obtained with a 32A46N5VBE wheel. In turning D-31 niobium, a tool life of 35 minutes was obtained at 300 ft/min. with a C-2 (K6) carbide, and a cutter life of 100 m-. of work travel in face milling with an M-2 HSS cutter at 98 ft/min. The best G Ratio, 7.5 for grinding D-31 was obtained with a 32A46K8VBE wheel using a KNO/sub 2/ solution grinding fluid. The 90Ta-10W alloy was somewhat more difficult to machine. Tool life in turning with a C-2 (K6) carbide was 25 min at 100 ft/min. In drilling, 45 holes were obtained with a 0.193 in. dia. M-1 HSS drill at 50 ft/min. Reaming with a 0.213 in. dia. M-2 HSS reamer at 85 ft/min gave 68 holes, and a tap life of 60 holes was obtained at 4 ft/min with a 1/4-28 M-10 HSS tap. In milling TZM molybdenum with a C-2 (883) carbide face mill at 350 ft/min a cutter life of 110 in. of work travel was obtained. A T-15 HSS end mill produced 80 in. of work travel at 190 ft/min. Drilling with a 0.250 in. dia. M-1 HSS drill produced 100 holes at 125 ft/min and reaming with a 0.272 in. dia. M-2 HSS reamer gave a tool life of 50 holes at 60 ft/min. Tapping with a 5/16-24 M-10 HSS tap at 70 ft/min produced 100 holes. Grinding ratios of 15 to 25 were obtained using aluminum oxide wheels with KNO/sub 2/ solution as a grinding fiuid. Silicon carbide wheels gave the best G Ratios, 30 to 40, in grinding a high temperature glass ceramic. Wheel speeds of 5000 to 6000 ft/mth and a down feed of 0.002 in./pass produced the best G Ratio.

Li(Ni{sub 0.4}Co{sub 0.15}Al{sub 0.05}Mn{sub 0.4})O{sub 2} was investigated to understand the effect of replacement of the cobalt by aluminum on the structural and electrochemical properties. In situ X-ray absorption spectroscopy (XAS) was performed, utilizing a novel in situ electrochemical cell, specifically designed for long-term X-ray experiments. The cell was cycled at a moderate rate through a typical Li-ion battery operating voltage range. (1.0-4.7 V) XAS measurements were performed at different states of charge (SOC) during cycling, at the Ni, Co, and the Mn edges, revealing details about the response of the cathode to Li insertion and extraction processes. The extended X-ray absorption fine structure (EXAFS) region of the spectra revealed the changes of bond distance and coordination number of Ni, Co, and Mn absorbers as a function of the SOC of the material. The oxidation states of the transition metals in the system are Ni{sup 2+}, Co{sup 3+}, and Mn{sup 4+} in the as-made material (fully discharged), while during charging the Ni{sup 2+} is oxidized to Ni{sup 4+} through an intermediate stage of Ni{sup 3+}, Co{sup 3+} is oxidized toward Co{sup 4+}, and Mn was found to be electrochemically inactive and remained as Mn{sup 4+}. The EXAFS results during cycling show that the Ni-O changes the most, followed by Co-O, and Mn-O varies the least. These measurements on this cathode material confirmed that the material retains its symmetry and good structural short-range order leading to the superior cycling reported earlier.

Preliminary plans to move the special nuclear material supporting category I and II missions from TA-18 to the device assembly facility  

SciTech Connect

In December 2002, the National Nuclear Security Agency (NNSA) issued a Record of Decision announcing its intent to relocate safeguards Category I and II missions and associated special nuclear materials (SNM) from Los Alamos National Laboratory (LANL) Technical Area 18 (TA-18) to the Device Assembly Facility (DAF) at the Nevada Test Site (NTS). The Cat I and II missions support nuclear criticality safety, nuclear emergency response, nuclear nonproliferation, and homeland security. TA-18 is the sole remaining facility in the United States with the capability to perform general-purpose nuclear materials handling experiments and training. Hands-on and remote control experiments, measurements, and training with special materials and devices are conducted. The conceptual design for modifying the DAF to house these Cat I and II missions includes plans for packaging and transporting the SNM inventory associated with the missions. This paper discusses these preliminary packaging and transporting plans, including how they fit into the plans for transitioning the relevant TA- 18 missions to DAF while ensuring that mission, cost, and schedule requirements are met.

Evaluation of a single cell and candidate materials with high water content hydrogen in a generic solid oxide fuel cell stack test fixture, Part II: materials and interface characterization  

Science Conference Proceedings (OSTI)

A generic solid oxide fuel cell (SOFC) test fixture was developed to evaluate candidate materials under realistic conditions. A commerical 50 mm x 50 mm NiO-YSZ anode supported thin YSZ electrolyte cell with lanthanum strontium manganite (LSM) cathode was tested to evaluate the stability of candidate materials. The cell was tested in two stages at 800oC: stage I of low (~3% H2O) humidity and stage II of high (~30% H2O) humidity hydrogen fuel at constant voltage or constant current mode. Part I of the work was published earlier with information of the generic test fixture design, materials, cell performance, and optical post-mortem analysis. In part II, detailed microstructure and interfacial characterizations are reported regarding the SOFC candidate materials: (Mn,Co)-spinel conductive coating, alumina coating for sealing area, ferritic stainless steel interconnect, refractory sealing glass, and their interactions with each other. Overall, the (Mn,Co)-spinel coating was very effective in minimizing Cr migration. No Cr was identified in the cathode after 1720h at 800oC. Aluminization of metallic interconnect also proved to be chemically compatible with alkaline-earth silicate sealing glass. The details of interfacial reaction and microstructure development are discussed.

Silicon Materials Task of the Low Cost Solar Array Project (Phase II). Effect of impurities and processing on silicon solar cells. Phase II. Summary and eleventh quarterly report  

DOE Green Energy (OSTI)

The effects of various processes, metal contaminants and contaminant-process interactions on the performance of terrestrial silicon solar cells were investigated. A variety of aspects including thermal treatments, crystal growth rate, base doping concentration (low resistivity), base doping type (n vs. p), grain boundary structure, and carbon/oxygen-metal interactions (float zone vs Czochralski growth) were studied. The effects of various metallic impurities were studied, introduced singly or in combination into Czochralski, float zone and polycrystalline silicon ingots and into silicon ribbons grown by the dendritic web process. The totality of the solar cell data (comprising over 4000 cells) indicate that impurity-induced performance loss is primarily due to reduction in base diffusion length. Based on this assumption an analytical model has been developed which predicts cell performance as a function of metal impurity content. The model has now been verified for p-base material by correlating the projected and measured performance of solar cells made on 19 ingots bearing multiple impurities.

Silicon Materials Task of the Low Cost Solar Array Project (Phase II). Sixth quarterly report, 1 January 1977--March 31, 1977  

DOE Green Energy (OSTI)

Preliminary studies have been conducted to develop a foundation for the work to be carried out in Phase II of the program, which is designed to investigate the effects of processes and impurities on terrestrial silicon solar cells. Solar cells nearly 10% efficient (without AR coatings) can be made on p-type material with resistivities down to about 0.2 ..cap omega..-cm using a process similar to that employed during Phase I of the program. As resistivity falls below about 0.1 ..cap omega..-cm cell efficiency also falls and process instabilities become more prevalent. For this reason the resistivity of the baseline material chosen to study the combined effects of boron and metal doping will probably be in the 0.1 to 0.3 ..cap omega..-cm range. Initial studies on n-base material indicate that 0.2 ..mu..m deep junctions with adequate sheet resistivities can be obtained by boron diffusion from BBr/sub 3/ at 875/sup 0/C. Slow cooling from the diffusion temperature appears necessary to maintain good lifetime and I/sub sc/ values. p/sup +//n/n/sup +/ cells fabricated on a Westinghouse internal program using this type of processing produce coated cells with 16% efficiencies.

The substitution vanishes  

E-Print Network (OSTI)

Abstract. Accumulation techniques were invented to transform functional programs, which intensively use append functions (like inefficient list reversal), into more efficient programs, which use accumulating parameters instead (like efficient list reversal). In this paper we present a generalized and automatic accumulation technique that also handles programs operating with unary functions on arbitrary tree structures and employing substitution functions on trees which may replace different designated symbols by different trees. We show that this transformation does not deteriorate the efficiency with respect to call-by-need reduction. 1

Energy-substitution in the paper industry in Brazil: A translog function approach  

Science Conference Proceedings (OSTI)

Unlike the majority of studies, this study focuses at the micro level instead of the aggregate. The method employed involves the use of econometric techniques to estimate translog cost and production functions, and the estimation of the Allen Elasticities of Substitution (AES) from the coefficients. The data used come from firms in the paper industry of Brazil during January, 1982 to December, 1987. When using aggregated data, findings concerning energy-capital substitution are often controversial. Some authors find substitutability, while others find complementarity between energy and capital. This study found that this ambiguity also appears at the micro level. Even when the firms belong to the same industry, two inputs can be complements in one firm and substitutes in another. The basic findings are: (1) Energy demand is found to be responsive to price changes, (2) Fossil fuels and biomass are substitutes, (3) Biomass and capital are substitutes, (4) Fossil fuels and hydroelectricity are complements, (5) Hydroelectricity and capital are complements, (6) Labor and materials are substitutes, and (7) Capital and labor are substitutes. The other elasticities are ambiguous, varying from firm to firm, or not significant at the 5% level.

An elastoplastic framework for granular materials becoming cohesive through mechanical densification. Part II - the formulation of elastoplastic coupling at large strain  

E-Print Network (OSTI)

The two key phenomena occurring in the process of ceramic powder compaction are the progressive gain in cohesion and the increase of elastic stiffness, both related to the development of plastic deformation. The latter effect is an example of `elastoplastic coupling', in which the plastic flow affects the elastic properties of the material, and has been so far considered only within the framework of small strain assumption (mainly to describe elastic degradation in rock-like materials), so that it remains completely unexplored for large strain. Therefore, a new finite strain generalization of elastoplastic coupling theory is given to describe the mechanical behaviour of materials evolving from a granular to a dense state. The correct account of elastoplastic coupling and of the specific characteristics of materials evolving from a loose to a dense state (for instance, nonlinear --or linear-- dependence of the elastic part of the deformation on the forming pressure in the granular --or dense-- state) makes the use of existing large strain formulations awkward, if even possible. Therfore, first, we have resorted to a very general setting allowing general transformations between work-conjugate stress and strain measures; second, we have introduced the multiplicative decomposition of the deformation gradient and, third, employing isotropy and hyperelasticity of elastic response, we have obtained a relation between the Biot stress and its `total' and `plastic' work-conjugate strain measure. This is a key result, since it allows an immediate achievement of the rate elastoplastic constitutive equations. Knowing the general form of these equations, all the specific laws governing the behaviour of ceramic powders are finally introduced as generalizations of the small strain counterparts given in Part I of this paper.

Using a profiling process to insure program quality: Volume II - support materials. Final progress report, May 15, 1991--November 14, 1996  

SciTech Connect

Between 1990 and 1995 the U.S. Department of Energy (DOE) and the National Center for Improving Science Education (National Center) developed a system for ongoing evaluation of K-12 educational programs in the DOE-supported national energy Laboratories. As part of the formative evaluation component of this collaborative endeavor, field staff in the Laboratories began creating profiles of their programs. However, many individuals within DOE Headquarters were not familiar with this profiling process and were unprepared to use the valuable information that the profiles generated. This manual was produced to orient Headquarters staff to profiling. It focuses on how Headquarters staff can use the profiling process to help their funded programs establish and/or maintain high quality. Its purpose, then, is not to train Headquarters staff to become proficient in profiling, but to show them how to draw on the Laboratories` use of profiling to bring about program improvement. Profiling is the process of systematically examining and describing a program`s elements against a set of components that define Effective Practice. The instrument used to capture the data for analysis is called a template, and most of this manual focuses on the templates and how to read and interpret them. However, since it is important to understand these data in context, the authors also describe what should accompany each template in a complete profiling packet and offer guidelines for reviewing complete packets and providing feedback to program managers. This document consists of Support Materials for the manual: exercise answer keys; templates; guidelines for reviewing templates; a complete profiling packet; guidelines for the trainer.

C?H Bond Activation by Pd-substituted CeO[subscript 2]: Substituted Ions versus Reduced Species  

Science Conference Proceedings (OSTI)

Substituted metal oxides containing ionic species have been attracting a great deal of attention because of their potential ability to reduce the usage of precious metals in heterogeneous catalysts. We investigate Pd-substituted CeO{sub 2} for C-H bond activation reactions including the partial oxidation and dry reforming of CH{sub 4}. This catalyst has been previously studied for CO oxidation, NO{sub x} reduction, and the water-gas shift reaction. Pd-substituted CeO{sub 2}, Ce{sub 1-x}Pd{sub x}O{sub 2-{delta}}, was prepared as a powder with high surface area and a hollow sphere morphology using ultrasonic spray pyrolysis. The catalysts were extensively characterized using synchrotron X-ray diffraction and other techniques, confirming phase pure samples up to 10 mol % Pd substitution. Ce{sub 0.95}Pd{sub 0.05}O{sub 2-{delta}} was found to be active for partial oxidation of CH{sub 4} around 500 C and higher. Our studies, including postcatalytic synchrotron diffraction, suggest that the single-phase Ce{sub 1-x}Pd{sub x}O{sub 2-{delta}} material is not the active species and that catalysis occurs instead over the reduced two-phase Pd{sup 0}/CeO{sub 2}. This observation has been further confirmed by verifying the activity of the reduced Pd{sup 0}/CeO{sub 2} catalysts for ethylene hydrogenation, a reaction that is known to require Pd{sup 0}.

UTILIZATION OF LIGHTWEIGHT MATERIALS MADE FROM COAL GASIFICATION SLAGS  

Science Conference Proceedings (OSTI)

The objective of the project entitled ''Utilization of Lightweight Materials Made from Coal Gasification Slags'' was to demonstrate the technical and economic viability of manufacturing low-unit-weight products from coal gasification slags which can be used as substitutes for conventional lightweight and ultra-lightweight aggregates. In Phase I, the technology developed by Praxis to produce lightweight aggregates from slag (termed SLA) was applied to produce a large batch (10 tons) of expanded slag using pilot direct-fired rotary kilns and a fluidized bed calciner. The expanded products were characterized using basic characterization and application-oriented tests. Phase II involved the demonstration and evaluation of the use of expanded slag aggregates to produce a number of end-use applications including lightweight roof tiles, lightweight precast products (e.g., masonry blocks), structural concrete, insulating concrete, loose fill insulation, and as a substitute for expanded perlite and vermiculite in horticultural applications. Prototypes of these end-use applications were made and tested with the assistance of commercial manufacturers. Finally, the economics of expanded slag production was determined and compared with the alternative of slag disposal. Production of value-added products from SLA has a significant potential to enhance the overall gasification process economics, especially when the avoided costs of disposal are considered.

Oxygen ion conducting materials  

DOE Patents (OSTI)

An oxygen ion conducting ceramic oxide that has applications in industry including fuel cells, oxygen pumps, oxygen sensors, and separation membranes. The material is based on the idea that substituting a dopant into the host perovskite lattice of (La,Sr)MnO.sub.3 that prefers a coordination number lower than 6 will induce oxygen ion vacancies to form in the lattice. Because the oxygen ion conductivity of (La,Sr)MnO.sub.3 is low over a very large temperature range, the material exhibits a high overpotential when used. The inclusion of oxygen vacancies into the lattice by doping the material has been found to maintain the desirable properties of (La,Sr)MnO.sub.3, while significantly decreasing the experimentally observed overpotential.

Can Vanadium Be Substituted into LiFePO4  

DOE Green Energy (OSTI)

Vanadium is shown to substitute for iron in the olivine LiFePO{sub 4} up to at least 10 mol %, when the synthesis is carried out at 550 C. In the solid solution LiFe{sub 1-3y/2}V{sub y}PO{sub 4}, the a and b lattice parameters and cell volume decrease with increasing vanadium content, while the c lattice parameter increases slightly. However, when the synthesis is performed at 650 C, a NASICON phase, Li{sub 3}V{sub 2}(PO{sub 4}){sub 3}, is also formed, showing that solid solution is a function of the synthesis temperature. X-ray absorption near-edge structure indicates vanadium is in the 3+ oxidation state and in an octahedral environment. Magnetic studies reveal a shift of the antiferromagnetic ordering transition toward lower temperatures with increasing vanadium substitution, confirming solid solution formation. The addition of vanadium enhances the electrochemical performance of the materials especially at high current densities.

Superconductivity in gallium-substituted Ba8Si46 clathrates  

E-Print Network (OSTI)

We report a joint experimental and theoretical investigation of superconductivity in Ga-substituted type-I silicon clathrates. We prepared samples of the general formula Ba8Si46-xGax, with different values of x. We show that Ba8Si40Ga6 is a bulk superconductor, with an onset at T-C approximate to 3.3 K. For x=10 and higher, no superconductivity was observed down to T=1.8 K. This represents a strong suppression of superconductivity with increasing Ga content, compared to Ba8Si46 with T-C approximate to 8 K. Suppression of superconductivity can be attributed primarily to a decrease in the density of states at the Fermi level, caused by a reduced integrity of the sp(3)-hybridized networks as well as the lowering of carrier concentration. These results are corroborated by first-principles calculations, which show that Ga substitution results in a large decrease of the electronic density of states at the Fermi level, which explains the decreased superconducting critical temperature within the BCS framework. To further characterize the superconducting state, we carried out magnetic measurements showing Ba8Si40Ga6 to be a type-II superconductor. The critical magnetic fields were measured to be H-C1 approximate to 35 Oe and H-C2 approximate to 8.5 kOe. We deduce the London penetration depth lambda approximate to 3700 A and the coherence length xi(c)approximate to 200 A. Our estimate of the electron-phonon coupling reveals that Ba8Si40Ga6 is a moderate phonon-mediated BCS superconductor.

Activation of methane by transition metal-substituted aluminophosphate molecular sieves  

DOE Patents (OSTI)

Aluminophosphate molecular sieves substituted with cobalt, manganese or iron and having the AlPO{sub 4}-34 or AlPO{sub 4}-5, or related AlPO{sub 4} structure activate methane starting at approximately 350{degree}C. Between 400 and 500{degree}C and at methane pressures {le} 1 atmosphere the rate of methane conversion increases steadily with typical conversion efficiencies at 500{degree}C approaching 50% and selectivity to the production of C{sub 2+} hydrocarbons approaching 100%. The cobalt substituted AlPO{sub 4}-34 structure (CoAPSO-34) produces ethylene, ethane, propylene, and propane in varying proportions, depending on reaction conditions. The cobalt-substituted AlPO{sub 4}-5 (CoAPSO-5) produces polypropylene in very high yield, with ethane, ethylene, and propane also produced. The activation mechanism is based on reduction of the transition metal (III) from of the molecular sieve to the transition metal(II) form with accompanying oxidative dehydrogenation of the methane. Reoxidation of the transition metal(II) form to the transition metal (III) form can be done either chemically (e.g., using O{sub 2}) or electrochemically. 4 figs.

In situ X-ray diffraction suggests the presence of Al has a significant structural impact during battery operation. It acts to limit the changes in lattice parameters observed during electrochemical charging and cycling of the materials. High-resolution X-ray diffraction reveals structural distortions in the transition metal layers of as-synthesized powders with high Al-contents, as well as a structural evolution seen in all materials after cycling.

U.S. Department of Energy Critical Materials Strategy  

Science Conference Proceedings (OSTI)

This report examines the role of rare earth metals and other materials in the clean energy economy. It was prepared by the U.S. Department of Energy (DOE) based on data collected and research performed during 2010. Its main conclusions include: (a) Several clean energy technologies -- including wind turbines, electric vehicles, photovoltaic cells and fluorescent lighting -- use materials at risk of supply disruptions in the short term. Those risks will generally decrease in the medium and long term. (b) Clean energy technologies currently constitute about 20 percent of global consumption of critical materials. As clean energy technologies are deployed more widely in the decades ahead, their share of global consumption of critical materials will likely grow. (c) Of the materials analyzed, five rare earth metals (dysprosium, neodymium, terbium, europium and yttrium), as well as indium, are assessed as most critical in the short term. For this purpose, 'criticality' is a measure that combines importance to the clean energy economy and risk of supply disruption. (d) Sound policies and strategic investments can reduce the risk of supply disruptions, especially in the medium and long term. (e) Data with respect to many of the issues considered in this report are sparse. In the report, DOE describes plans to (i) develop its first integrated research agenda addressing critical materials, building on three technical workshops convened by the Department during November and December 2010; (ii) strengthen its capacity for information-gathering on this topic; and (iii) work closely with international partners, including Japan and Europe, to reduce vulnerability to supply disruptions and address critical material needs. DOE will work with other stakeholders -- including interagency colleagues, Congress and the public -- to shape policy tools that strengthen the United States' strategic capabilities. DOE also announces its plan to develop an updated critical materials strategy, based upon additional events and information, by the end of 2011.DOE's strategy with respect to critical materials rests on three pillars. First, diversified global supply chains are essential. To manage supply risk, multiple sources of materials are required. This means taking steps to facilitate extraction, processing and manufacturing here in the United States, as well as encouraging other nations to expedite alternative supplies. In all cases, extraction and processing should be done in an environmentally sound manner. Second, substitutes must be developed. Research leading to material and technology substitutes will improve flexibility and help meet the material needs of the clean energy economy. Third, recycling, reuse and more efficient use could significantly lower world demand for newly extracted materials. Research into recycling processes coupled with well-designed policies will help make recycling economically viable over time.The scope of this report is limited. It does not address the material needs of the entire economy, the entire energy sector or even all clean energy technologies. Time and resource limitations precluded a comprehensive scope. Among the topics that merit additional research are the use of rare earth metals in catalytic converters and in petroleum refining. These topics are discussed briefly in Chapter 2.

Structure, thermal expansion and electrical conductivity of Nb-substituted LaCoO{sub 3}  

Science Conference Proceedings (OSTI)

The effect of Nb-substitution in LaCoO{sub 3} has been examined by evaluating the electrical conductivity, thermal expansion and crystal structure of the solid solutions LaCo{sub 1-x}Nb{sub x}O{sub 3} (x=0 to 1/3). It was demonstrated that Nb-substitution in LaCoO{sub 3} was mainly compensated by reduction of Co{sup 3+} to Co{sup 2+}, and that oxidation of Co{sup 2+} could destabilise the solid solution. The ambient crystal structure was shown to transform from rhombohedral R3{sup Macron }c perovskite (x=0) to orthorhombic Pbnm (x=0.15, 0.20) and finally to B-site ordered perovskite P2{sub 1}/n (x=0.25, 1/3) perovskite with increasing Nb-substitution. The thermal expansion of LaCo{sub 1-x}Nb{sub x}O{sub 3} was shown to be strongly depressed with increasing Nb-content, and significantly lower thermal expansion was observed for LaCo{sub 2/3}Nb{sub 1/3}O{sub 3} relative to LaCoO{sub 3}. The electrical conductivity was reduced with increasing Nb-content, and semi-conducting properties was demonstrated for LaCo{sub 1-x}Nb{sub x}O{sub 3} in contrast to the metallic behaviour of pure LaCoO{sub 3} at elevated temperature. The thermal expansion, electrical conductivity and the stability of the materials were discussed with emphasis on Co/Nb ordering, the oxidation state and spin transitions of Co. - Graphical abstract: Substitution of Nb in LaCoO{sub 3} increases the unit cell volume, reduces the symmetry of the unit cell and introduces cation ordering. The chemical substitution leads to suppression of the electronic conductivity and reduces the thermal expansion of the lattice. Highlights: Black-Right-Pointing-Pointer Cation ordering and crystal structure is reported for LaCo{sub x}Nb{sub 1-x}O{sub 3}. Black-Right-Pointing-Pointer Substitution of Nb in LaCoO{sub 3} is compensated by reduction of Co{sup 3+} to Co{sup 2+}. Black-Right-Pointing-Pointer Thermal expansion of LaCoO{sub 3} is reduced by Nb-substitution. Black-Right-Pointing-Pointer Electrical conductivity of LaCoO{sub 3} is reduced by Nb-substitution.

MULTISCALE PHENOMENA IN MATERIALS  

Science Conference Proceedings (OSTI)

This project developed and supported a technology base in nonequilibrium phenomena underpinning fundamental issues in condensed matter and materials science, and applied this technology to selected problems. In this way the increasingly sophisticated synthesis and characterization available for classes of complex electronic and structural materials provided a testbed for nonlinear science, while nonlinear and nonequilibrium techniques helped advance our understanding of the scientific principles underlying the control of material microstructure, their evolution, fundamental to macroscopic functionalities. The project focused on overlapping areas of emerging thrusts and programs in the Los Alamos materials community for which nonlinear and nonequilibrium approaches will have decisive roles and where productive teamwork among elements of modeling, simulations, synthesis, characterization and applications could be anticipated--particularly multiscale and nonequilibrium phenomena, and complex matter in and between fields of soft, hard and biomimetic materials. Principal topics were: (i) Complex organic and inorganic electronic materials, including hard, soft and biomimetic materials, self-assembly processes and photophysics; (ii) Microstructure and evolution in multiscale and hierarchical materials, including dynamic fracture and friction, dislocation and large-scale deformation, metastability, and inhomogeneity; and (iii) Equilibrium and nonequilibrium phases and phase transformations, emphasizing competing interactions, frustration, landscapes, glassy and stochastic dynamics, and energy focusing.

Differential scanning calorimetry of metamict Pu-substituted zirconolite  

DOE Green Energy (OSTI)

Samples of CaPuTi/sub 2/O/sub 7/ were prepared by cold pressing and sintering. Plutonium was substituted for zirconium in order to characterize radiation damage effects. The energy stored in a sample which had reached saturation in swelling after storage at ambient temperature was measured with a differential scanning calorimeter. The total energy of 6.6 +- 0.1 cal/g is released over the range 485 to 715/sup 0/C. The activation energy of annealing of the damage is 1.22 +- 0.05 eV. The temperature dependence of the rate constant is described by k/sub T/ = 5.96E4 exp(-1.22/k/sub B/T) s/sup -1/ where kB and T are the Boltzmann's constant and temperature (K) respectively. A sample stored at 600/sup 0/C was similarly evaluated and showed no release of stored energy to the precision of the apparatus (+- 0.1 cal/g). These results are applied to analysis of waste incorporation in SYNROC and are correlated with analogous parameters for other materials.

Technical Change, Factor Demand and Interfactor/Interfuel Substitution  

E-Print Network (OSTI)

Abstract: With its rapid economic growth, China’s primary energy consumption has exceeded domestic energy production since 1994, leading to a substantial expansion in energy imports, particularly of oil. China’s energy demand has an increasingly significant impact on global energy markets. In this paper Allen partial elasticities of factor and energy substitution, and price elasticities of energy demand, are calculated for China using a two-stage translog cost function approach. The results suggest that energy is substitutable with both capital and labour. Coal is significantly substitutable with electricity and complementary with diesel while gasoline and electricity are substitutable with diesel. China’s energy intensity is increasing during the study period (1995-2004) and the major driver appears to be due to the increased use of energy intensive technology.

Production of Substitute Natural Gas from Coal  

DOE Green Energy (OSTI)

The goal of this research program was to develop and demonstrate a novel gasification technology to produce substitute natural gas (SNG) from coal. The technology relies on a continuous sequential processing method that differs substantially from the historic methanation or hydro-gasification processing technologies. The thermo-chemistry relies on all the same reactions, but the processing sequences are different. The proposed concept is appropriate for western sub-bituminous coals, which tend to be composed of about half fixed carbon and about half volatile matter (dry ash-free basis). In the most general terms the process requires four steps (1) separating the fixed carbon from the volatile matter (pyrolysis); (2) converting the volatile fraction into syngas (reforming); (3) reacting the syngas with heated carbon to make methane-rich fuel gas (methanation and hydro-gasification); and (4) generating process heat by combusting residual char (combustion). A key feature of this technology is that no oxygen plant is needed for char combustion.

BEATRIX-II, phase II: Data summary report  

SciTech Connect

The BEATRIX-II experimental program was an International Energy Agency sponsored collaborative effort between Japan, Canada, and the United States to evaluate the performance of ceramic solid breeder materials in a fast-neutron environment at high burnup levels. This report addresses the Phase II activities, which included two in situ tritium-recovery canisters: temperature-change and temperature-gradient. The temperature-change canister contained a Li{sub 2}O ring specimen that had a nearly uniform temperature profile and was capable of temperature changes between 530 and 640{degrees}C. The temperature-gradient canister contained a Li{sub 2}ZrO{sub 3} pebble bed operating under a thermal gradient of 440 to 1100{degrees}C. Postirradiation examination was carried out to characterize the Phase II in situ specimens and a series of nonvented capsules designed to address the compatibility of beryllium with lithium-ceramic solid-breeder materials. The results of the BEATRIX-II, Phase II, irradiation experiment provided an extensive data base on the in situ tritium-release characteristics of Li{sub 2}O and Li{sub 2}ZrO{sub 3} for lithium burnups near 5%. The composition of the sweep gas was found to be a critical parameter in the recovery of tritium from both Li{sub 2}O and Li{sub 2}ZrO{sub 3}. Tritium inventories measured confirmed that Li{sub 2}O and Li{sub 2}ZrO{sub 3} exhibited very low tritium retention during the Phase II irradiation. Tritium inventories in Li{sub 2}ZrO{sub 3} after Phase II tended to be larger than those found for Li{sub 2}ZrO{sub 3} in other in situ experiments, but the larger values may reflect the larger generation rates in BEATRIX-II. A series of 20 capsules was irradiated to determine the compatibility of lithium ceramics and beryllium under conditions similar to a fusion blanket. It is concluded that Li{sub 2}O and Li{sub 2}ZrO{sub 3} should remain leading candidates for use in a solid-breeder fusion-blanket application.

Layered manganese oxide intergrowth electrodes for rechargeable lithium batteries: Part 1-substitution with Co or Ni  

DOE Green Energy (OSTI)

Lithium manganese oxides substituted with nickel or cobalt were characterized electrochemically in lithium cell configurations. The compounds studied were either single-phase layered structures with either primarily O2 or O3 stacking arrangements, or O2/O3 intergrowths, prepared from P2, P3 and P2/P3 sodium-containing precursors, respectively. The stacking arrangements are extremely sensitive to the Na/T. M. (T. M. = transition metal) ratios and the level of substitution. Phase diagrams showing the stability regions of the various arrangements for the Na-Ni-Mn-O system are presented. A possible correlation between vacancies and electrochemical performance is suggested. For high levels of substitution with Ni, fewer defects are possible for materials containing more O3 component and higher discharge capacities can be achieved, but spinel conversion upon cycling also occurs more rapidly as the O3 content increases. Intergrowths show intermediate behavior and represent a potential route towards designing stable, high capacity electrodes.

Catalytic Partial oxidation of n-Tetradecane Using Pyrochlores: Effect of Rh and Sr Substitution  

SciTech Connect

The catalytic partial oxidation (CPOX) of transportation fuels into synthesis gas (H2 + CO) for fuel cells is complicated by the large quantities of aromatics and sulfur-containing compounds commonly found in these fuels. Traditional supported metal catalysts are easily poisoned by these species which adsorb strongly onto the electron-rich metal clusters. The use of noble metal and/or oxide based catalyst systems may offer higher activity and stability, but only if the metal can be bound into a thermally stable structure. To that end, Rh metal was substituted into the structure of a lanthanum zirconate (LZ) pyrochlore to give La2RhyZr(2#2;y)O(7-j,) (LRZ) to produce a strongly bound, well-dispersed metal which is active for CPOX. A second catalyst was prepared in which Sr was substituted for a portion of La in the LRZ structure, producing La(2#2;x)SrxRhyZr(2#2;y)O(7-j) (LSRZ). Each of these pyrochlore catalysts, including the unsubstituted LZ, were characterized and screened for activity in the CPOX of ntetradecane (TD), which is a surrogate for linear paraffins typical of diesel fuel. Results were compared to a commercial Rh/g-Al2O3 catalyst. X-ray diffraction patterns of both the LZ and LRZ showed that each had the cubic unit-cell pyrochlore structure. However, substitution of Sr resulted in a binary perovskite-pyrochlore phase with a defect SrZrO3 phase. Hydrogen pulse chemisorption and temperature programmed reduction studies confirmed that Rh metal was substituted into the structure of the LRZ and LSRZ, and was reducible. Activity screening with the CPOX of TD showed that the Rh substituted in both LRZ and LSRZ is able to retain activity-producing essentially equilibrium synthesis gas yields, as was the Rh/g-Al2O3. Temperature programmed oxidation experiments performed after the CPOX of TD demonstrated that the amount of carbon was quantitatively similar for each catalyst (roughly 0.3 gcarbon/gcatalyst after each run), with the exception of LSRZ, which had significantly less carbon (0.17 gcarbon/gcatalyst). It is speculated that improved oxygen ion mobility in the LSRZ material, which resulted from Sr substitution, was responsible for the reduction in carbon formation on the surface.

thermoelectric materials  

E-Print Network (OSTI)

It has been proven that the maximum cooling temperature of a thermoelectric material can be increased by using either pulsed operation or graded Seebeck profiles. In this paper, we show that the maximum cooling temperature can be further increased by the pulsed operation of optimal inhomogeneous thermoelectric materials. A random sampling method is used to obtain the optimal electrical conductivity profile of inhomogeneous materials, which can achieve a much higher cooling temperature than the best uniform materials under the steady-state condition. Numerical simulations of pulsed operation are then carried out in the time domain. In the limit of low thermoelectric figure-of-merit ZT, the finite-difference time-domain simulations are verified by an analytical solution for homogeneous material. This numerical method is applied to high ZT BiTe materials and simulations show that the effective figure-of-merit can be improved by 153 % when both optimal graded electrical conductivity profiles and pulsed operation are used. 1.

Factors Affecting the Battery Performance of Anthraquinone-based Organic Cathode Materials  

Science Conference Proceedings (OSTI)

Two organic cathode materials based on poly(anthraquinonyl sulfide) structure with different substitution positions were synthesized and their electrochemical behavior and battery performances were investigated. The substitution positions on the anthraquinone structure, binders for electrode preparation and electrolyte formulations have been found to have significant effects on the battery performances of such organic cathode materials. The substitution position with less steric stress has higher capacity, longer cycle life and better high-rate capability. Polyvinylidene fluoride binder and ether-based electrolytes are favorable for the high capacity and long cycle life of the quinonyl organic cathodes.

Effect of storage temperature on self-irradiation damage of /sup 238/Pu-substituted zirconolite  

SciTech Connect

/sup 238/Pu-substituted cubic zirconolite (CaPuTi/sub 2/O/sub 7/) was stored at ambient temperature, 575/sup 0/ K, and 875/sup 0/ K until alpha decay doses of 2.4 to 3.6 x 10/sup 25//m/sup 3/ had been accumulated. The ambient temperature material swelled to a saturation value of 5.5 vol %, and the originally crystalline structure was transformed to one with an amorphous matrix and small domains that had retained their crystallinity. At 575/sup 0/ K, lesser amounts of swelling (4.1 vol %) and transformation were observed, reflecting concurrent partial recovery. The material held at 875/sup 0/ K remained crystalline, swelled only 0.4 vol %, and exhibited formation of isolated defect clusters. 5 figures.

Silicon Materials Task of the Low Cost Solar Array Project (Phase II). Effect of impurities and processing on silicon solar cells. Tenth quarterly report, 1 January 1978--31 March 1978  

DOE Green Energy (OSTI)

The objective of this program is to determine how various processes, impurities and impurity-process interactions affect the properties of silicon and the performance of terrestrial solar cells made from silicon. The development of this data base permits the definition of the tolerable impurity levels in a low-cost solar grade silicon and identifies processes which mitigate or enhance impurity effects in silicon. The data further provide the silicon manufacturer with a means to select materials of construction which minimize product contamination and permit the cost effective selection of chemical processes for silicon purification. For the silicon ingot, sheet or ribbon manufacturer the data suggest what silicon feedstock purity must be selected to produce wafers suitable for cell production and what furnace materials minimize wafer contamination. The cell manufacturer may use the data to define an acceptable wafer purity for cell processing or to identify processes which minimize impurity impact on efficiency. In short the data provide a basis for cost-benefit analysis to the producers and users of Solar Grade Silicon. During this quarter the focus of the experimental activity has been in the following four areas: (1) effects of crystal growth rate and thermal processing of silicon on impurity distribution and electrical activity, (2) impurity-grain boundary interactions in polycrystalline silicon, (3) preliminary measurements of impurity trap levels, trap concentrations and capture cross sections by Deep Level Transient Spectroscopy of purposely contaminated solar cells and (4) improvement of the solar cell-impurity concentration data base for n- and p-type silicon for subsequent modeling studies.

Flibe Coolant Cleanup and Processing in the HYLIFE-II Inertial Fusion Energy Power Plant  

SciTech Connect

In the HYLIFE-II chamber design, a thick flowing blanket of molten-salt (Li{sub 2}BeF{sub 4}) called flibe is used to protect structures from radiation damage. Since it is directly exposed to the fusion target, the flibe will absorb the target debris. Removing the materials left over from target explosions at the rate of {approx}6/s and then recycling some of these materials poses a challenge for the inertial fusion energy power plant. The choice of target materials derives from multi-disciplinary criteria such as target performance, fabricability, safety and environment, corrosion, and cost of recycle. Indirect-drive targets require high-2 materials for the hohlraum. Gold and gadolinium are favorite target materials for laboratory experiments but cost considerations may preclude their use in power plants or at least requires cost effective recycle because a year's supply of gold and gadolinium is estimated at 520 M$ and 40 M$. Environmental and waste considerations alone require recycle of this material. Separation by volatility appears to be the most attractive (e.g., Hg and Xe); centrifugation (e.g., Pb) is acceptable with some problems (e.g., materials compatibility) and chemical separation is the least attractive (e.g. Gd and Hf). Mercury, hafnium and xenon might be substituted with equal target performance and have advantages in removal and recycle due to their high volatility, except for hafnium. Alternatively, lead, tungsten and xenon might be used due to the ability to use centrifugation and gaseous separation. Hafnium or tantalum form fluorides, which will complicate materials compatibility, corrosion and require sufficient volatility of the fluoride for separation. Further complicating the coolant cleanup and processing is the formation of free fluorine due to nuclear transformation of lithium and beryllium in the flibe, which requires chemical control of the fluoride level to minimize corrosion. The study of the choice of target materials and the appropriate processing needs further study because we have not come up with choices which perform as well as gold and gadolinium and which have practical processes for recovery and recycle.

Method and apparatus for measuring the permeability of polymer film materials such as used in super-insulation powder-filled evacuated panels (PEPs) reduce the time required for testing from several years to weeks or months. The method involves substitution of a solid non-outgassing body having a free volume of between 0% and 25% of its total volume for the usual powder in the PEP to control the free volume of the "body-filled panel". Pressure versus time data for the test piece permit extrapolation to obtain long term performance of the candidate materials.

Solution Synthesis and Processing of PZT Materials for Neutron Generator Applications  

SciTech Connect

A new solution synthesis route has been developed for the preparation of lead-based ferroelectric materials (patent filed). The process produces controlled stoichiometry precursor powders by non-aqueous precipitation. For a given ferroelectric material to be prepared, a metal acetate/alkoxide solution containing constituent metal species in the appropriate ratio is mixed with an oxalic acid/n-propanol precipitant solution. An oxalate coprecipitate is instantly fonned upon mixing that quantitatively removes the metals from solution. Most of the process development was focused on the synthesis and processing of niobium-substituted lead zirconate titanate with a Zr-to-Ti ratio of 95:5 (PNZT 95/5) that has an application in neutron generator power supplies. The process was scaled to produce 1.6 kg of the PNZT 95/5 powder using either a sen-ii-batch or a continuous precipitation scheme. Several of the PNZT 95/5 powder lots were processed into ceramic slug form. The slugs in turn were processed into components and characterized. The physical properties and electrical performance (including explosive functional testing of the components met the requirements set for the neutron generator application. Also, it has been demonstrated that the process is highly reproducible with respect to the properties of the powders it produces and the properties of the ceramics prepared from its powders. The work described in this report was funded by Sandia's Laboratory Directed Research and Development Program.

Solvent Refined Coal-II (SRC-II) detailed environmental plan  

Science Conference Proceedings (OSTI)

This document describes environmental research which will: aid in the development of an environmentally acceptable SRC-II process; and provide data for environmental assessment of the process. The SRC-II process is described, criteria for selection of samples to undergo environmental analyses are given, and approximate timelines are presented for obtaining pertinent samples. At this time, the SRC-II process is at the pilot-plant stage of development and a demonstration facility is scheduled to begin operation in 1984. Since design criteria may change, the environmental research described in this document is organized in four phases which correlate with and will provide information early in process development. Phase I research (screening) evaluates samples from existing SRC-II facilities (pilot, process demonstration unit (PDU), bench) which may bracket potential demonstration/commercial practice in terms of physical and chemical criteria. The samples are being subjected to a battery of short-term biomedical and ecological assays. Chemical fractionation and analysis are being performed to determine compounds and compound classes of potential concern. Phase II (baseline) research will evaluate SRC-II materials which are considered most representative of potential demonstration/commercial practice. These materials will be subjected to longer-term, more-extensive biological and ecological analyses relative to effects and environmental fate. Phase III research will examine effects of process modification, control technologies and changing operational conditions on potential environmental properties of SRC-II materials. Phase IV research (onsite monitoring) will develop methods and initiate environmental monitoring for effects at the SRC-II demonstration facility and potential commercial sites. This document also describes industrial hygiene programs which must occur throughout SRC-II process development.

TRUPACT-II residue pipe payload container  

SciTech Connect

This paper summarizes the project to develop, test and certify a new payload container for the TRUPACT-II, a Type B packaging for the shipment of transuranic waste. The new payload container will provide segregation of plutonium waste materials within the TRUPACT-II. This segregation of fissile contents will support a new criticality safety analysis that may allow an increase in the TRUPACT-II Pu-239 Fissile Gram Equivalent (FGE) limit from 325 grams to 2800 grams. The need for this project was brought about by the end of the Cold War and the resulting shift in value of plutonium residues from providing recoverable Defense Program material to being considered disposable waste. This paper will not cover many of the details of the project but will instead aim to provide a general picture of all the project activities.

Thermoelectric materials development. Final report  

DOE Green Energy (OSTI)

A systematic search for advanced thermoelectric materials was initiated at JPL several years ago to evaluate candidate materials which includes consideration of the following property attributes: (1) semiconducting properties; (2) large Seebeck coefficient; (3) high carrier mobility and high electrical conductivity; (4) low lattice thermal conductivity; and (5) chemical stability and low vapor pressure. Through this candidate screening process, JPL identified several families of materials as promising candidates for improved thermoelectric materials including the skutterudite family. There are several programs supporting various phases of the effort on these materials. As part of an ongoing effort to develop skutterudite materials with lower thermal conductivity values, several solid solutions and filled skutterudite materials were investigated under the effort sponsored by DOE. The efforts have primarily focused on: (1) study of existence and properties of solid solutions between the binary compounds CoSb{sub 3} and IrSb{sub 3}, and RuSb{sub 2}Te, and (2) CeFe{sub 4{minus}x}Sb{sub 12} based filled compositions. For the solid solutions, the lattice thermal conductivity reduction was expected to be reduced by the introduction of the Te and Ru atoms while in the case of CeFe{sub 4{minus}x}Ru{sub x}Sb{sub 12} based filled compositions. For the solid solutions, the lattice thermal conductivity reduction was expected to be reduced by the introduction of the Te and Ru atoms while in the case of CeFe{sub 4{minus}x}Ru{sub x}Sb{sub 12} filled compositions, the reduction would be caused by the rattling of Ce atoms located in the empty voids of the skutterudite structure and the substitution of Fe for Ru. The details of the sample preparation and characterization of their thermoelectric properties are reported in this report.

Electrochemical and structural characterization of titanium-substituted manganese oxides based on Na0.44MnO2  

DOE Green Energy (OSTI)

A series of titanium-substituted manganese oxides, Li{sub x}Ti{sub y}Mn{sub 1-y}O{sub 2} (y = 0.11, 0.22, 0.33, 0.44, and 0.55) with the Na{sub 0.44}MnO{sub 2} structure were prepared from Na{sub x}Ti{sub y}Mn{sub 1-y}O{sub 2} (x {approx} 0.44) precursors. The electrochemical characteristics of these compounds, which retain the unique double-tunnel structure during ion exchange, were examined in lithium/polymer electrolyte cells operating at 85 C. All of the substituted cathode materials intercalated lithium reversibly, with Li{sub x}Ti{sub 0.22}Mn{sub 0.78}O{sub 2} exhibiting the highest capacity in polymer cells, about 10-20% greater than that of unsubstituted Li{sub x}MnO{sub 2} made from Na{sub 0.44}MnO{sub 2}. In common with Li{sub x}MnO{sub 2}, the Ti-substituted materials exhibited good capacity retention over one hundred or more cycles, with some compositions exhibiting a fade rate of less than 0.03% per cycle.

Wishart, Henry Taube, Kenneth J. Breslauer and Stephan S. Isied Inorg. Chem. 25, 1479-1481 (1986) Abstract: An estimate of the enthalpy change associated with the substitution of H2O on (NH3)5RuOH22+ with NO+(aq) has been made by thermochemical measurements on a cycle of reactions, which includes the reaction of (NH3)5RuOH22+ with NO2-(aq) and which involves the assumption that the heat of dissolution of NOBF4(s) to produce NO+(aq) + BF4-(aq) is close to the heat of dissolution of CsBF4(s). The chemistry is complicated because the reaction of (NH3)5RuOH22+ with NO2-(aq) ultimately produces trans-[(NH3)4Ru(OH)NO]2+(aq) rather than [(NH3)5RuNO]3+(aq). Reasonably

Photovoltaic Materials  

Science Conference Proceedings (OSTI)

The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNL’s unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted projects with industry members. ORNL has the capabilities in place and the expertise required to understand how basic material properties including defects, impurities, and grain boundaries affect the solar cell performance. ORNL also has unique processing capabilities to optimize the manufacturing process for fabrication of high efficiency and low cost solar cells. ORNL recently established the Center for Advanced Thin-film Systems (CATS), which contains a suite of optical and electrical characterization equipment specifically focused on solar cell research. Under this project, ORNL made these facilities available to industrial partners who were interested in pursuing collaborative research toward the improvement of their product or manufacturing process. Four specific projects were pursued with industrial partners: Global Solar Energy is a solar industry leader in full scale production manufacturing highly-efficient Copper Indium Gallium diSelenide (CIGS) thin film solar material, cells and products. ORNL worked with GSE to develop a scalable, non-vacuum, solution technique to deposit amorphous or nanocrystalline conducting barrier layers on untextured stainless steel substrates for fabricating high efficiency flexible CIGS PV. Ferro Corporation’s Electronic, Color and Glass Materials (“ECGM”) business unit is currently the world’s largest supplier of metallic contact materials in the crystalline solar cell marketplace. Ferro’s ECGM business unit has been the world's leading supplier of thick film metal pastes to the crystalline silicon PV industry for more than 30 years, and has had operational cells and modules in the field for 25 years. Under this project, Ferro leveraged world leading analytical capabilities at ORNL to characterize the paste-to-silicon interface microstructure and develop high efficiency next generation contact pastes. Ampulse Corporation is developing a revolutionary crystalline-silicon (c-Si) thin-film solar photovoltaic (PV) technology. Utilizing uniquely-textured substrates and buffer materials from the Oak Ridge National Laboratory (ORNL), and breakthroughs in Hot-Wire Chemical Vapor Deposition (HW-CVD) techniques in epitaxial silicon developed at the National Renewable Energy Laboratory (NREL), Ampulse is creating a solar technology that is tunable in silicon thickness, and hence in efficiency and economics, to meet the specific requirements of multiple solar PV applications. This project focused on the development of a high rate deposition process to deposit Si, Ge, and Si1-xGex films as an alternate to hot-wire CVD. Mossey Creek Solar is a start-up company with great expertise in the solar field. The primary interest is to create and preserve jobs in the solar sector by developing high-yield, low-cost, high-efficiency solar cells using MSC-patented and -proprietary technologies. The specific goal of this project was to produce large grain formation in thin, net-shape-thickness mc-Si wafers processed with high-purity silicon powder and ORNL's plasma arc lamp melting without introducing impurities that compromise absorption coefficient and carrier lifetime. As part of this project, ORNL also added specific pieces of equipment to enhance our ability to provide unique insight for the solar industry. These capabilities include a moisture barrier measurement system, a combined physical vapor deposition and sputtering system dedicated to cadmium-containing deposits, adeep level transient spectroscopy system useful for identifying defects, an integrating sphere photoluminescence system, and a high-speed ink jet printing system. These tools were combined with others to study the effect of defects on the performance of crystalline silicon and

Investigations of the Biological Roles of Substituted Cyclohexadienes  

E-Print Network (OSTI)

In recent years there have been two cycloterpenals, molecules consisting of a cyclohexadienal core, isolated from nature. Cyclocitral, the condensation product of citral, has been isolated from the North Sea bryozoans Flustra foliacea. In the human eyes, cycloretinal has been isolated and is a toxic by product of the vision cycle. This retinal dimer is believed to contribute to age related macular degeneration, the leading cause of blindness in the elderly. In 1992, it was discovered that if [beta]-ionylideneacetaldehyde was incubated with beta-lactoglobulin ([beta]-LG), the principal whey protein in dairy milk, that it would mediate the formation of cyclo-[beta]-ional. No follow up studies were performed on this protein mediated reaction or what biological activities these cycloterpenals may possess. This dissertation investigates the biological roles of substituted cyclohexadienes including cycloterpenals and cyclohexadiene enaminonitriles. To mimic the protein mediated reaction, we developed a synthetic procedure to produce a wide array of cycloterpenal by utilizing L-proline. Over 100 cycloterpenals were synthesized and screened for their biological activities against an array of cell based screens. The phenotypic effects of these cycloterpenals were screened against a PC12 assay where dramatic effects were observed on neurite outgrowth. During the synthesis of starting materials for the production of our cycloterpenal library, it was discovered that if excess base was added to the Horner-Wadsworth-Emmons reaction between a methyl-ketone and diethyl-(cyanomethyl)-phosphonate, conversion of the [alpha]-[beta]-unsaturated nitrile into an enaminonitrile was observed. This new synthetic procedure was optimized to generate a library of enaminonitriles as well as their quinazoline derivatives. The work within also includes the investigation of the [beta]-LG mediated reaction formation of cycloterpenals with natural and unnatural [beta]-methyl aldehydes. We were able to demonstrate that [beta]-LG could mediate the conversion of [alpha],[beta]-unsaturated aldehydes into their corresponding cycloterpenal. In vitro analysis was also performed with store bought milks and the [beta]-LG present was able to mediate the formation of cyclocitral. An in vivo experiment was also performed by utilizing New Zealand White rabbits to demonstrate the formation of cycloretinal within the blood stream by feeding a source of [beta]-LG with retinal. Interestingly, in human blood, [beta]-LG is present at concentrations of 0.7-1.2 g/dL. The protein has been identified within drusen pigments and lipofuscin granules that accumulate in the retina of macular degeneration patients. As humans do not produce beta-lactoglobulin, the source of this protein is from milk and milk products. With these experiments, we clearly demonstrate that under the appropriate conditions, cycloretinal can be produced with [beta]-LG. We have clearly established a direct link between [beta]-LG chemistry and age-related macular degeneration.

Functional Substitution Methods in Optimization for Bayesian Tomography  

E-Print Network (OSTI)

1 Bayesian tomographic reconstruction algorithms generally require the efficient optimization of a functional of many variables. In this setting as well as many other optimization tasks, functional substitution (FS) has been widely applied to simplify each step of the iterative process. The function to be minimized is replaced locally by an approximation having a more easily manipulated form, e.g. quadratic, but which maintains sufficient similarity to descend the true functional while computing only the substitute. In this paper, we provide two new applications of FS methods in iterative coordinate descent for Bayesian tomography. The first is a modification of our recently proposed coordinate descent algorithm with 1-D Newton-Raphson approximations to an alternative quadratic which allows convergence to be proven easily. In simulations we find essentially no difference in convergence speed between the two techniques. We also present a new algorithm which exploits the FS method to all...

Economics of producing substitute natural gas from coal. Occasional pub  

Science Conference Proceedings (OSTI)

Using the cost levelization approach, the economics of producing substitute natural gas (SNG) are examined under different assumptions regarding conversion technologies, coal types and plant financing. A comparison of levelized constant dollar cost-of-service price estimated for Westinghouse and dry bottom Lurgi processes for 1990-2019 shows that SNG from coal produced at western sites is competitive with natural gas and fuel oils.

CO oxidation on substituted copper chromite spinel oxide catalysts  

Science Conference Proceedings (OSTI)

Oxidation of carbon monoxide was studied on Mg- and Al-substituted CuCr[sub 2]O[sub 4] spinel catalyst at atmospheric pressure and temperatures between 373 and 723 K. The activity of CuCr[sub 2]O[sub 4] decreased even for small replacements of either Cu by Mg or Cr by Al and none of the substituted oxides was as active as CuCr[sub 2]O[sub 4]. In Cu[sub 1[minus]x]Mg[sub x]Cr[sub 2]O[sub 4] catalysts, the activity systematically decreased with increasing x, except for 0.4 < x < 0.6. The decrease in activity is due to a decrease in the active Cu[sup 2+] ions of the catalyst. The increase in activity on increasing x from 0.4 to 0.6 is attributed to the crystallographic phase change, i.e., tetragonal to cubic, in the catalyst. This was also found in the CuCr[sub 2[minus]x]Al[sub x]O[sub 4] catalysts. The decrease in the catalytic activity on substitution of Cr by Al, even when the total copper content is not altered, is due to the reduction of some of the active Cu[sup 2+] ions to Cu[sup 1+] ions. 10 refs., 9 figs., 2 tabs.

Rapid Microwave Preparation of Highly Efficient Ce[superscript 3+]-Substituted Garnet Phosphors for Solid State White Lighting  

SciTech Connect

Ce{sup 3+}-substituted aluminum garnet compounds of yttrium (Y{sub 3}Al{sub 5}O{sub 12}) and lutetium (Lu{sub 3}Al{sub 5}O{sub 12}) - both important compounds in the generation of (In,Ga)N-based solid state white lighting - have been prepared using a simple microwave heating technique involving the use of a microwave susceptor to provide the initial heat source. Carbon used as the susceptor additionally creates a reducing atmosphere around the sample that helps stabilize the desired luminescent compound. High quality, phase-pure materials are prepared within a fraction of the time and using a fraction of the energy required in a conventional ceramic preparation; the microwave technique allows for a reduction of about 95% in preparation time, making it possible to obtain phase pure, Ce{sup 3+}-substituted garnet compounds in under 20 min of reaction time. It is estimated that the overall reduction in energy compared with ceramic routes as practiced in the lab is close to 99%. Conventionally prepared material is compared with material prepared using microwave heating in terms of structure, morphology, and optical properties, including quantum yield and thermal quenching of luminescence. Finally, the microwave-prepared compounds have been incorporated into light-emitting diode 'caps' to test their performance characteristics in a real device, in terms of their photon efficiency and color coordinates.

Materials Project: A Materials Genome Approach  

DOE Data Explorer (OSTI)

Technological innovation - faster computers, more efficient solar cells, more compact energy storage - is often enabled by materials advances. Yet, it takes an average of 18 years to move new materials discoveries from lab to market. This is largely because materials designers operate with very little information and must painstakingly tweak new materials in the lab. Computational materials science is now powerful enough that it can predict many properties of materials before those materials are ever synthesized in the lab. By scaling materials computations over supercomputing clusters, this project has computed some properties of over 80,000 materials and screened 25,000 of these for Li-ion batteries. The computations predicted several new battery materials which were made and tested in the lab and are now being patented. By computing properties of all known materials, the Materials Project aims to remove guesswork from materials design in a variety of applications. Experimental research can be targeted to the most promising compounds from computational data sets. Researchers will be able to data-mine scientific trends in materials properties. By providing materials researchers with the information they need to design better, the Materials Project aims to accelerate innovation in materials research.[copied from http://materialsproject.org/about] You will be asked to register to be granted free, full access.

Composition-structure-property-performance relationship inMn-substituted LiMn2O4  

DOE Green Energy (OSTI)

The spinel LiMn{sub 2}O{sub 4} has been extensively studied as a positive electrode active material in lithium rechargeable batteries. Partial substitution of Mn by another metal has also been the subject of recent study in an effort to improve the cycling performance. In general, the literature has shown that Mn substitution results in improved cycling stability at the expense of capacity (1,2). Resistance to the formation of tetragonal phase upon lithiation of the starting spinel (via a higher nominal Mn oxidation state in the substituted spinel) has been suggested as a mechanism for the improved performance. The degree of substitution is an important factor to optimize in order to minimize capacity loss and costs. The spectroscopic investigations on LiMn{sub 2}O{sub 4} described in the previous paper (LixMn2O4) confirmed that the cooperative Jahn-Teller effect (CJTE) from the [Mn{sup 3+}O{sub 6}] octahedra is the mechanism for the cubic to tetragonal phase transformation. The driving force for the CJTE is based upon the electronic structure, therefore changes in electronic structure should lead to changes in the phase behavior. The fact that the LiMn{sub 1.5}Ni{sub 0.5}O{sub 4} does not form tetragonal phase upon discharging (FUJI3, MUCK?), unlike the 100% Mn{sup 4+} spinel Li{sub 4}Mn{sub 5}O{sub 12} (THAC5), led to the hypothesis that an increased degree of covalency as a source for the behavior. An increased covalence would remove the driving force for the transformation, the increased electronic stability achieved in tetragonally-distorted [Mn{sup 3+}O{sub 6}] octahedra, due to a change in electron density and widening of the Mn 3d bands. The STH field is dependent upon the amount of unpaired spin density transferred between the magnetic (transition-metal) and diamagnetic ions through an intermittent oxygen ion, attributable to overlap and electron transfer effects. Therefore, the magnitude of the STH coupling constant reflects the degree of covalency (GESC, HUAN). In the case of LiMn{sub 2-y}Me{sub y}O{sub 4}, the STH coupling constant characterizes the amount of unpaired spin density transferred to the Li{sup +} from the Mn, Co, or Ni. Similarly, the La/Lb ratio of the Mn L-XES is sensitive to the amount of electron density at the Mn site as a higher ratio indicates that the Mn 3d{sub 5/2} level is more populated (GRUS1). An investigation into the effects of Mn-substitution on the electronic structure along with the ramifications to the phase behavior upon changing lithium content was carried out. To accomplish this, a set of LiMn{sub 2-y}Me{sub y}O{sub 4} with Me = Li, Co, or Ni over a range of y were synthesized, characterized, and subjected to changes in lithium content by various techniques.

The Use of Manganese Substituted Ferrotitanium Alloys for Energy Storage  

DOE Green Energy (OSTI)

Experimental results are presented on properties of major practical importance in the utilization of manganese-substituted ferrotitanium alloys as hydrogen storage media. Consideration is given to (1) pressure-composition-temperature characteristics, (2) particle attrition properties, (3) effects of long-term cycling on alloy stability, (4) ease of activation and reactivation, and (5) effects of contaminants on alloy activity. The performance of ternary alloys is compared with that of titanium iron as is the development of an optimum ternary alloy for use with a particular peak shaving operation, i.e., the regenerative H2-Cl system.

Materials Informatics: Fast Track to New Materials  

SciTech Connect

Current methods for new materials development focus on either deeper fundamental-level studies or generation of large quantities of data. The data challenge in materials science is not only the volume of data being generated by many independent investigators, but its heterogeneity and also its complexity that must be transformed, analyzed, correlated and communicated. Materials informatics addresses these issues. Materials informatics is an emerging information-based field combining computational, statistical, and mathematical approaches with materials sciences for accelerating discovery and development of new materials. Within the informatic framework, the various different forms of information form a system architecture, an iterative cycle for transforming data into knowledge.

Materials used in new generation vehicles: supplies, shifts, and supporting infrastructure  

DOE Green Energy (OSTI)

The Partnership for a New Generation of Vehicles (PNGV) program intends to develop new designs for automobiles that will reduce fuel consumption by two thirds but otherwise have price, comfort, safety, and other measures of performance similar to the typical automobile now on the market. PNGV vehicle designs are expected to substitute lightweight materials, such as aluminum, magnesium, carbon-reinforced polymer composites, glass-reinforced polymer composites, and ultra- light steel, for heavier materials such as steel and iron in automobile components. The target mass of a PNGV vehicle is 1,960 pounds, as compared to the average current vehicle that weights 3,240 pounds. Other changes could include the use of different ferrous alloys, engineering changes, or incorporation of advanced ceramic components. Widespread adoption of these vehicle designs would affect materials markets and require concurrent development and adoption of supporting technologies to supply the materials and to use and maintain them in automobiles. This report identifies what would be required to bring about these changes and developments in materials substitution; identifies reasons that might make these substitutions difficult to accomplish within the overall objectives and timetable of the PNGV program; and identifies any issues arising from the substitution that could prompt consideration of policies to deal with them. The analysis in this paper uses scenarios that assume the production of new generation vehicles will begin in 2007 and that their market share will increase gradually over the following 25 years. The scenarios on which the analysis is based assume a maximum substitution of each potential replacement material considered. This maximum substitution of individual materials (i.e., the amount of replacement material by weight that would be added to the baseline vehicle`s composition) is as follows: ULSAB (high strength steel), 298 lbs.; glass-reinforced composites, 653 lbs.; carbon-reinforced composites, 379 lbs.; aluminum, 926 lbs.; and magnesium, 216 lbs. The substitutions (and the steel and iron they replace) are multiplied by the number of new generation vehicles produced on an annual basis out to 2030 to determine the total quantity of material used in new generation vehicles and the quantity of steel that would be displaced. We identified six stages in the life cycle of materials--mining or extraction of resources; smelting or other processing to produce the material from the resource; producing components from the material; assembling the components into vehicles, using, maintaining, and repairing vehicles; and disposing of the vehicle, including any recycling of materials for automotive or other use--and identified what might be required to supply and use the substitute materials at different life cycle stages. The variables considered are the mineral or material supply, the capital and equipment (including necessary capacity, technical changes, cost, and location), labor and employment, energy, material complements, and environmental emissions and impacts. The analysis shows that raw materials to produce each of the replacement materials are sufficiently available, and adequate mining or extraction capacity exists for each. However, challenges are possible at the material production stage for three of the four materials. For aluminum and magnesium the difficulties are associated with requirements for significant new production capacity, necessary for aluminum because new production equipment will be needed to produce the material in a cost-effective manner and for magnesium because current production capacity is inadequate. The required capacity investment for magnesium to meet demand in 2030 is $13.1 billion. Both materials also would sharply increase energy requirements, and both industries would likely develop mostly--if not entirely--outside the United States. To produce the carbon-based fiber to meet PNGV demand in 2015, an entire new industry must be developed--a $4.6 billion investment. Significant environmental concerns

Coal gasification construction materials: an overview  

SciTech Connect

Materials performance test results are presented for two coal gasification processes, HYGAS SNG process, which converts any type of coal to substitute natural gas (SNG), and U-GAS fuel gas process, which converts coal to a low- or medium-heat value gas. A description of the pilot plant for each process and discussion of some experiences with materials and components used in plant construction is presented. Metals performance inside the gasifier reactors and in off-gas locations depended upon the character of the process. At moderate operating temperatures (427/sup 0/C), low-carbon steels are advisable. Very high-temperature environments may not only require use of exotic alloys, clads, and/or coatings but may also preclude extensive use of internal piping/valving in scale-up designs. Inconel 182, 600, and Monel 400 have all performed erratically in the plants; but in quench and purification sections, austenitic stainless steels performed well. 9 references. (BLM)

Guidelines for identifying suspect/counterfeit material  

SciTech Connect

These guidelines are intended to assist users of products in identifying: substandard, misrepresented, or fraudulently marked items. The guidelines provide information about such topics as: precautions, inspection and testing, dispositioning identified items, installed inspection and reporting suspect/counterfeit materials. These guidelines apply to users who are developing procurement documents, product acceptance/verification methods, company procedures, work instructions, etc. The intent of these SM guidelines in relation to the Quality Assurance Program Description (QAPD) and implementing company Management Control Procedures is not to substitute or replace existing requirements, as defined in either the QAPD or company implementing instructions (Management Control Procedures). Instead, the guidelines are intended to provide a consolidated source of information addressing the issue of Suspect/Counterfeit materials. These guidelines provide an extensive suspect component listing and suspect indications listing. Users can quickly check their suspect items against the list of manufacturers products (i.e., type, LD. number, and nameplate information) by consulting either of these listings.

Adsorption, desorption, and stabilization of arsenic on aluminum substituted ferrihydrite  

E-Print Network (OSTI)

Because of As toxicity, the complexity of its chemistry, and the recent lowering of the maximum contaminant level of As in municipal drinking water, there has been considerable interest for improved methods to remove As from water. Although Al and Fe hydroxides have been extensively studied as adsorbents for As removal during water treatment, coprecipitated Al:Fe hydroxides have received only minimal attention. The theoretical and experimental feasibility of coprecipitated Al:Fe hydroxide systems were evaluated by studying their mineralogy, stability, and As adsorption and desorption behavior. The broad XRD peaks revealed that Al was substituted into the ferrihydrite structure and that this was the only major product up to about a 2:8 Al:Fe molar ratio. Gibbsite and bayerite were identified when Al content was higher. The rate of recrystallization of ferrihydrite into goethite and hematite was significantly reduced as Al substitution was increased. In general, adsorption capacity of both AsV and AsIII decreased with increase in Al:Fe molar ratio; however, similar AsV adsorption capacities were observed with Fe and Al:Fe hydroxides with Al:(Al+Fe) molar ratios hydroxides were observed at pH 3 to 7, and that of AsV on Al hydroxide was observed at pH 5.2, with significant decreases in adsorption with increase and decrease in pH. Adsorption maxima of AsIII decreased by approximately 4 % for each 10 % increase in Al substitution up to 5:5 Al:Fe molar ratio. Adsorption maxima of AsIII on Fe and Al:Fe hydroxides were observed at pH 8 to 9. AsIII adsorption on Al hydroxide was negligible. Counterion Ca2+, compared to Na+, enhanced the retention of AsV, especially at pH > 7. Counterion concentration did not significantly affect AsV adsorption. Though phosphate desorbed both AsV and AsIII from all Al:Fe hydroxides, quantitative desorption was never observed. The results of this study indicate the possible utility of coprecipitated Al:Fe hydroxide in wastewater treatment. Based on adsorption/desorption behavior and stability of the Al:Fe hydroxide product, the preferred Al:Fe molar ratio was 2:8.

Measuring Range Anxiety: the Substitution-Emergency-Detour (SED) Method  

Science Conference Proceedings (OSTI)

Range anxiety has been widely recognized as a critical barrier for battery electric vehicles (BEV), but its measurement method is lacking. Such a knowledge gap makes it difficult to analyse the competiveness of and the demand for BEVs. This study develops the Substitution-Emergency-Detour (SED) method to measure the range anxiety cost, and conducts sensitivity analysis of range anxiety cost with respect to nine factors. It is found that the most effective ways to reduce range anxiety are reducing driving intensity, increasing the vehicle range, extending the vehicle range with better charging infrastructure. Better household vehicle flexibility and less range uncertainty can also significantly reduce range anxiety. The SED method and the numerical results are expected to contribute to better understanding of the range anxiety barrier and the BEV demand.

Test Plan for Composite Hydrogen Getter Materials  

SciTech Connect

The intent of this test plan is to provide details of the Savannah River Technology Center (SRTC) effort to evaluate composite getter materials for eventual use in expanding the wattage limits for transportation of contact-handled transuranic waste (CH-TRU). This effort is funded by the Mixed Waste Focus Area (MWFA) under Technical Task Plan (TTP) SR-1-9-MW-45 and is the result of a competitive process initiated by a MWFA request for proposals. In response to this request, SRTC presented data on several composite getter materials that demonstrated good potential for application in transportation of transuranic wastes. The tests outlined in the SRTC proposal for composite getter materials should demonstrate compliance with functional requirements provided by the MWFA in a Statement of Work (SOW) which accompanied the request for proposals. Completion of Phase 1 testing, as defined in the TTP, should provide sufficient data to determine if composite getters should progress to Phase s 2 and 3. These test results will provide support for future safety reviews as part of the Transuranic Package Transporter-II (TRUPACT-II) certification process to utilize getter technology. This test plan provides details of the test descriptions, test objectives, required measurements, data quality objectives, data analysis, and schedule information relevant to Phase 1 of the TTP. The results of these tests are expected to help identify any potential weaknesses in the use of composite getter for transportation of CH-TRU wastes. Where a potential weakness is identified, this will be addressed as part of Phase 2 of the proposed effort. It is also important to recognize that these tests are focused on the individual composite getter materials and not the engineered system that would eventually be used in a TRUPACT-II. However, these test results will be very helpful in establishing the requirements for the design of a TRUPACT-II getter system that is included as part of the propo sed Phase 3 effort.

Effect of Nickel Substitution on Defect Chemistry, Electrical Properties, and Dimensional Stability of Calcium-Doped Yttrium Chromite  

SciTech Connect

The effect of nickel substitution on defect chemistry, electrical properties, and dimensional stability of calcium-doped yttrium chromite was studied for use as an interconnect material in high temperature solid oxide fuel cells (SOFCs). The compositions of Y0.8Ca0.2Cr1-xNixO3±? (x=0-0.15), prepared using the glycine nitrate process, showed single phase orthorhombic perovskite structures over a wide range of oxygen partial pressures (10^-17 atm ? pO2 ? 0.21 atm). X-ray diffraction (XRD) analysis indicated that most of the nickel ions replacing chromium ions are divalent and act as acceptor dopants, leading to a substantial increase in conductivity. In particular, the conductivity at 900 degree C in air increased from 10 S/cm to 34 S/cm with 15% nickel substitution, and an increase in charge carrier density was confirmed by Seebeck measurements. A point defect model was derived, and the relationship between electrical conductivity and oxygen partial pressure was successfully fitted into the proposed model. The defect modeling results indicated that nickel substitution improves the stability of calcium-doped yttrium chromite toward reduction and suppresses the oxygen vacancy formation, which results in significantly increased electrical conductivity in reducing environment. The electrical conductivity of Y0.8Ca0.2Cr0.85Ni0.15O3±? at 900 degree C in reducing atmosphere (pO2=10^-17 atm) was 5.8 S/cm, which was more than an order of magnitude higher than that of Y0.8Ca0.2CrO3±? (0.2 S/cm). Improved stability in reducing atmosphere was further confirmed by dilatometry measurements showing reduced isothermal "chemical" expansion, and the isothermal expansion in reducing atmosphere (pO2=10^-17 atm) at 900 degree C decreased from 0.07% for Y0.8Ca0.2CrO3±? to 0.03% for Y0.8Ca0.2Cr0.85Ni0.15O3±?. Based on these results, enhanced electrical performance and mechanical integrity is expected with nickel substitution on calcium-doped yttrium chromite in SOFC operating conditions.

Two magnets will be produced, both of which will be inserted within the solenoidal detector at one of the collision points. Since the best use of the quadrupole focusing in this case requires placing the magnet as close to the collision point as possible, these magnets will be used within the magnetic field of the detector. This constrains the materials that can be used for construction to only non-magnetic materials. It also places severe demands on the structure of the magnet and it's holding supports due to the reaction forces between the solenoid and the magnet.

NLE Websites -- All DOE Office Websites (Extended Search)

Nanoscale-Ordered Materials Diffractometer Nanoscale-Ordered Materials Diffractometer Inside the NOMAD detector tank. Inside the NOMAD detector tank. NOMAD is a high-flux, medium-resolution diffractometer that uses a large bandwidth of neutron energies and extensive detector coverage to carry out structural determinations of local order in crystalline and amorphous materials. It enables studies of a large variety of samples ranging from liquids, solutions, glasses, polymers, and nanocrystalline materials to long-range-ordered crystals. The enhanced neutron flux at SNS, coupled with the advanced neutron optics and detector features of NOMAD, allows for unprecedented access to high-resolution pair distribution functions, small-contrast isotope substitution experiments, small sample sizes, and parametric studies.

Modeling dynamic substitution processes in energy supply systems  

SciTech Connect

Dynamic substitution processes between energy-conversion techniques are very important phenomena for the restructuring of energy systems. Using the method of synergetics, the authors develop a probabilistic model framework for individual decisions and their effects on the macroscopic configuration of energy supply systems. The derived probability transition rates are associated with socioeconomic parameters that are the basis for individual decisions. The authors state preliminary results of a case study for the room heating of private households in the former West Germany, which are based on a small data sample and a nonrepresentative poll. They find that the number of heating systems of one type, which are already installed, their ease of use, and the cost are the most important parameters for the selection of a new heating system. Using the estimated parameters, they simulate the diffusion of a new type of heating system, which is regarded as better than all the others, into the energy supply system. Its market share will reach 11--18% after 35 years.

Substitution-permutation networks, pseudorandom functions, and Natural Proofs  

E-Print Network (OSTI)

This paper takes a new step towards closing the troubling gap between pseudorandom functions (PRF) and their popular, bounded-input-length counterparts. This gap is both quantitative, because these counterparts are more efficient than PRF in various ways, and methodological, because these counterparts usually fit in the substitutionpermutation network paradigm (SPN) which has not been used to construct PRF. We give several candidate PRF Fi that are inspired by the SPN paradigm. This paradigm involves a “substitution function ” (S-box). Our main candidates are: F1: {0,1} n ? {0,1} n is an SPN whose S-box is a random function on b = O(lgn) bits, given as part of the seed. We prove unconditionally that F1 resists attacks that run in time ? 2 ?b. Setting b = ?(lgn) we obtain an inefficient PRF, which however seems to be the first such construction using the SPN paradigm. F2: {0,1} n ? {0,1} n is an SPN where the S-box is (patched) field inversion, a common choice in practical constructions. F2 is computable with Boolean circuits of size n · log O(1) n, and in particular with seed length n·log O(1) n. We prove that this

Hazardous Solvent Substitution Data System reference manual. Revision 1  

SciTech Connect

Concern for the environment, in addition to Federal regulation, mandate the replacement of hazardous solvents with safer cleaning agents. Manufacturers are working to produce these replacement solvents. As these products are developed, potential users need to be informed of their availability. To promote the use of these new products instead of traditional solvents, the Idaho National Engineering Laboratory (INEL) has developed the Hazardous Solvent Substitution Data System (HSSDS). The HSSDS provides a comprehensive system of information on alternatives to hazardous solvents and related subjects, and it makes that information available to solvent users, industrial hygienists, and process engineers. The HSSDS uses TOPIC{reg_sign}, a text retrieval system produced by Verity, Inc., to allow a user to search for information on a particular subject. TOPIC{reg_sign} produces a listing of the retrieved documents and allows the use to examine the documents individually and to use the information contained in them. This reference manual does not replace the comprehensive TOPIC{reg_sign} user documentation (available from Verity, Inc.), or the HSSDS Tutorial (available from the INEL). The purpose of this reference manual is to provide enough instruction on TOPIC{reg_sign} so the user may begin accessing the data contained in the HSSDS.

Joining of dissimilar materials  

DOE Patents (OSTI)

A method of joining dissimilar materials having different ductility, involves two principal steps: Decoration of the more ductile material's surface with particles of a less ductile material to produce a composite; and, sinter-bonding the composite produced to a joining member of a less ductile material. The joining method is suitable for joining dissimilar materials that are chemically inert towards each other (e.g., metal and ceramic), while resulting in a strong bond with a sharp interface between the two materials. The joining materials may differ greatly in form or particle size. The method is applicable to various types of materials including ceramic, metal, glass, glass-ceramic, polymer, cermet, semiconductor, etc., and the materials can be in various geometrical forms, such as powders, fibers, or bulk bodies (foil, wire, plate, etc.). Composites and devices with a decorated/sintered interface are also provided.

Characterization of carbonaceous materials using extraction with supercritical pentane  

Science Conference Proceedings (OSTI)

The use of carbonaceous adsorbents is limited by irreversible adsorption of some compounds so the use of supercritical pentane as an extracting solvent was examined. Carbon black appeared to be broken down slowly, but continuously, by the penane. To see if other types of carbon behaved similarly, high purity graphite, technical grade graphites, active carbons, and charcoals were examined. The extracts were characterized by uv spectroscopy, packed column chromatography using flame ionization and flame photometric detectors, and capillary GC/MS. The extracts were characteristic for each class of carbonaceous material. The high purity graphite yielded large, polycyclic aromatic compounds; the technical grade graphites yielded alkanes and alkyl-substituted benzenes and naphthalenes; the active carbons yielded alkanes, dienes, and small amounts of alkyl-substituted benzenes; and the charcoals yielded almost entirely alkanes in small amounts.

Materials/Condensed Matter Print Materials/Condensed Matter Print Materials research provides the foundation on which the economic well being of our high-tech society rests. The impact of advanced materials ranges dramatically over every aspect of our modern world from the minutiae of daily life to the grand scale of our national economy. Invariably, however, breakthroughs to new technologies trace their origin both to fundamental research in the basic properties of condensed matter and to applied research aimed at manipulating properties (structural, physical, chemical, electrical, magnetic, optical, etc.). Increasingly, the frontiers of materials research include materials that are "strongly correlated," characterized by strong coupling between a material's electrons with other electrons, magnetism, or the material lattice itself. This coupling often results in novel behavior, such as superconductivity, that may lead to technologically important applications.

Tailoring of porous materials involves not only chemical synthetic techniques for tailoring microscopic properties such as pore size, pore shape, pore connectivity, and pore surface reactivity, but also materials processing techniques for tailoring the meso- and the macroscopic properties of bulk materials in the form of fibers, thin films and monoliths. These issues are addressed in the context of five specific classes of porous materials: oxide molecular sieves, porous coordination solids, porous carbons, sol-gel derived oxides, and porous heteropolyanion salts. Reviews of these specific areas are preceded by a presentation of background material and review of current theoretical approaches to adsorption phenomena. A concluding section outlines current research needs and opportunities.

Mechanisms of growth inhibition induced by methylene-substituted and ring-substituted dims in breast cancer cells  

E-Print Network (OSTI)

One in 8 women will be diagnosed with breast cancer in the United States and estrogen receptor (ER) status largely influences the type and subsequent success of treatment employed. Although ER-positive breast cancer can be treated with endocrine therapy, the more invasive ER-negative breast cancer is non-responsive to this therapy and cytotoxic agents are often utilized which are associated with many adverse side effects. Consequently, there is a genuine need to develop more effective, less toxic treatments for invasive breast cancer. Indole-3-carbinol is a phytochemical found in cruciferous vegetables and one of its major metabolites, 3,3’-diindolylmethane (DIM), exhibits a broad range of anticancer and antitumorigenic activities. ER-negative MDA-MB-231 and MDA-MB-453 breast cancer cell growth was inhibited after treatment with a novel series of methylenesubstituted DIMs (C-DIMs), namely 1,1-bis(3’-indolyl)-1-(p-substitutedphenyl) methanes containing trifluoromethyl (DIM-C-pPhCF3), t-butyl (DIM-C-pPhtBu) and phenyl (DIM-C-pPhC6H5) groups. In addition, DIM-C-pPhC6H5 (40 mg/kg/d) inhibited tumor growth in nude mice bearing MDA-MB-231 cells as xenografts. Treatment of breast cancer cells with C-DIMs lead to downregulation of cyclin D1 and induction of non-steroidal anti-inflammatory drug-activated gene 1. Detection of necrosis, caspasedependent or caspase-independent apoptosis were not observed in breast cancer cells treated with C-DIMs, however autophagic cell death was induced by C-DIMs. DIM and ring-substituted DIMs have exhibited antitumorigenic activity in tumor murine mammary models. An investigation into the mechanism of cell death induced by DIM and 5,5’-dibromoDIM (5,5’-diBrDIM) in both ER-positive (MCF-7) and ERnegative (MDA-MB-231) breast cancer cells revealed modulation of several key signaling pathways involved in growth control. Both DIM and 5,5’-diBrDIM downregulated cyclin D1, although only 5,5’-diBrDIM induced a depolarization of the mitochondrial membrane. In addition, apoptosis was observed in MCF-7 cells treated with 5,5’-diBrDIM but not MDA-MB-231 cells. In summary, C-DIMs may represent new mechanism-based agents for treatment of breast cancer through induction of autophagic cell death. The ring-substituted DIMs correspond to a novel class of uncharged mitochondrial poisons that are also highly effective in inhibiting breast cancer cell growth. Results of this research provide evidence for the potential role of two new series of DIM analogs for the treatment of highly aggressive breast cancer.

BOAST II for the IBM 3090 and RISC 6000  

SciTech Connect

BOAST II simulates isothermal, darcy flow in three dimensions. It assumes that reservoir liquids can be described in three fluid phases (oil, gas, and water) of constant composition, with physical properties that depend on pressure, only. These reservoir fluid approximations are acceptable for a large percentage of the world's oil and gas reservoirs. Consequently, BOAST II has a wide range of applicability. BOAST II can simulate oil and/or gas recovery by fluid expansion, displacement, gravity drainage, and capillary imbibition mechanisms. Typical field production problems that BOAST II can handle include primary depletion studies, pressure maintenance by water and/or gas injection, and evaluation of secondary recovery waterflooding and displacement operations. Technically, BOAST II is a finite, implicit pressure, explicit saturation (IMPES) numerical simulator. It applies both direct and iterative solution techniques for solving systems of algebraic equations. The well model allows specification of rate or pressure constraints on well performance, and the user is free to add or to recomplete wells during the simulation. In addition, the user can define multiple rock and PVT regions and can choose from three aquifer models. BOAST II also provides flexible initialization, a bubble-point tracking scheme, automatic time-step control, and a material balance check on solution stability. The user controls output, which includes a run summary and line-printer plots of fieldwide performance.

NUCLEAR FUEL MATERIAL  

DOE Patents (OSTI)

An improved method is given for making the carbides of nuclear fuel material. The metal of the fuel material, which may be a fissile and/or fertile material, is transformed into a silicide, after which the silicide is comminuted to the desired particle size. This silicide is then carburized at an elevated temperature, either above or below the melting point of the silicide, to produce an intimate mixture of the carbide of the fuel material and the carbide of silicon. This mixture of the fuel material carbide and the silicon carbide is relatively stable in the presence of moisture and does not exhibit the highly reactive surface condition which is observed with fuel material carbides made by most other known methods.

High Performance Materials > Chrome Oxide Refractory High Performance Materials > Chrome Oxide Refractory Advanced Research High Performance Materials Chrome Oxide Refractory One notable NETL success is the development of a chrome oxide refractory material capable of working in slagging gasifier conditions. In this project, researchers first determined that one of the major failure mechanisms for chrome oxide refractories exposed to the intense heat and corrosive environment was spalling, or the chipping or flaking of refractory material from an exposed face. They used this information to formulate a high-chrome oxide refractory composition that resists spalling, resulting in a refractory with a longer service life in the gasifier. Inside an ultrasupercritical (USC) pulverized coal power plant, materials are exposed to temperatures up to 760°C and pressures up to 5,000 psi. Operating a USC system can improve power plant efficiency up to 47% and reduce emissions. However, finding boiler and turbine materials that can hold up under extreme conditions requires new high-temperature metal alloys and ceramic coatings, as well as computational modeling research to optimize the processing of these materials. Advanced Research Materials Development program successes in this area include the following:
