Chromizing of 3Cr Steel  

Science Conference Proceedings (OSTI)

Grade 315 steel (Fe-2.9 Cr-1.7 W-0.7 Mo-0.3 Mn-0.3 Si-0.2 V-0.1 Ni-0.13 C-0.01 N) was chromized by the halide-activated pack cementation (HAPC) process. Key process parameters, i.e., coating temperatures and pack compositions, were investigated. Ammonium chloride-activated packs in the 700-1000 C range produced coatings nominally in the 1-8 {micro}m range, as determined by optical and scanning electron microscopy (SEM). Coatings applied in the 900-1000 C temperature range resulted in Cr-rich coatings. The predominant phase in the coating was identified as Cr23C6 by X-ray diffraction. In addition, the presence of chromium nitride, Cr2N, was observed in the coating. The power generation industry is faced with an ever-increasing demand for energy while simultaneously having to reduce carbon emissions. These goals can be facilitated by increasing plant efficiency through the use of higher operating temperatures and pressures. Traditional construction materials, e.g., the ferritic Grade 22 high strength low alloy steel, are limited to operations below {approx} 550 C. Therefore, new materials are required for future plants designed to operate up to 650 C and possibly higher. These new materials need to have improved tensile strength, ductility, toughness, corrosion resistance, and creep properties at elevated temperatures. Oak Ridge National Laboratory (ORNL) is investigating the oxidation and creep behavior of various coatings on Grade 315 steel (Fe-2.9 Cr-1.7 W-0.7 Mo-0.3 Mn-0.3 Si-0.2 V-0.1 Ni-0.13 C-0.01 N), a super-bainitic steel developed for superior creep properties. Thin, chemical vapor-deposited (CVD) aluminide coatings were used to compensate for the reduced corrosion and oxidation resistance that resulted from the low chromium content of the alloy. However, the aluminized Grade 315 alloys performed less-than-favorably under conditions relevant to fossil boilers, leading to the conclusion that higher chromium contents are required for the formation of corrosion-resistant oxide scales in these environments. The halide activated pack cementation (HAPC) process offers a promising low-cost and versatile alternative to CVD as a means of improving corrosion resistance via formation of a protective Cr-containing coating.

MASSIE MASSIE SANTOS BALLON The Sequencing, Finishing, Analysis in the Future Meeting first convened in Santa Fe, New Mexico five years ago. Back then, the conference title was much shorter, and the crowd in attendance much smaller. The 2006 Meeting primarily focused on genome finishing technologies and how new sequencing technologies would impact them. Over the years, the Meeting's focus has moved from simply genome finishing to how next genera- tion sequencing technologies have affected genomics over- all in assembly, finishing, annotation and analysis. Claire Fraser-Liggett sum- marized the current state of genomic research succinctly in her opening keynote of the 5th annual meeting held June 2-4, 2010: "We're not in Kansas anymore, and yet we are." Addressing a record crowd of 250 attendees, Fraser- Liggett discussed current sequencing technologies and applications

MASSIE SANTOS BALLON MASSIE SANTOS BALLON The 5th Annual DOE Joint Genome Institute "Genomics of Energy & Environment" User Meeting started off on a provo- cative note: the first speaker, Dennis Hedgecock of the University of Southern California, compared eating an oyster to "kissing the sea on the lips." Given the meeting's focus on genomics for energy and the environment, Hedgecock was quick to note that Pacific oys- ters can annually sequester the amount of carbon equiva- lent to that produced by the African nation of Cameroon during the same period. He said researchers are interested in finding ways to boost the oyster's ability to capture carbon just as biofuels researchers are interested in using the idea of hybrid vigor to boost biomass production in energy crops.

Catalytic dewaxing of middle distillates  

SciTech Connect

The fractionation and stripping equipment of a middle distillate catalytic dewaxing unit may be eliminated by integrating the catalytic dewaxing unit with a catalytic cracking unit. The light cycle oil sidestream from the cat cracker fractionator, bypasses the sidestream stripper and serves as the feed to the catalytic dewaxing unit. The dewaxed product is separated into a gasoline fraction which is recycled for fractionation in the cat cracker fractionator and a fuel oil fraction which is recycled to the cat cracker sidestream stripper for removal of light materials to produce a low pour fuel oil meeting product specifications.

The influence of thallium on the redox reaction CrT /CrS  

Science Conference Proceedings (OSTI)

Investigations on the kinetics and electrocatalysis of the CrT /CrS reaction were carried out. By means of cyclic voltammetry, it was discovered that the addition of thallium-I-chloride not only accelerates the CrT /CrS reaction in HC1 electrolytes catalytically, using graphite electrodes with small amounts of Au, but also raises th hydrogen overvoltage more than lead and bismuth, the heavy metal catalysts already tested in the practical redox cells. Investigations concerning the reaction rate, the influence of chrome ion concentrations, the electrolyte storage time, temperature, and the presence of iron are being conducted.

Armageddon, oil, and the Middle East crisis  

SciTech Connect

This book relates the intricate subject of biblical prophecy to the current crisis in the Middle East. With the development of oil politics, Dr. Walvoord believes a new world government will emerge, centered in the Middle East, which will eclipse the United States and Russia as world powers. The world government will be subjected to catastrophic, divine judgments which precipitate a gigantic world war culminating in Armageddon. Each chapter is devoted to the scriptural explanations of events leading to the second coming of Christ. The result is a prophetic calendar summing up to the countdown to Armageddon. Some of the chapter titles include: the Arab oil blackmail; watch Jerusalen; the rising tide of world religion; the coming Middle East peace; the coming world dictator; and Armageddon: the world's death struggle.

Spin density distribution in CrCl/sub 3/ and CrBr/sub 3/  

SciTech Connect

The magnetization distribution in the layered ionic compounds CrCl/sub 3/ and CrBr/sub 3/ has been studied using polarized neutron diffraction. The results show that in both compounds approx. 20% of the magnetic moment is not located in 3d- like orbitals centered on the chromium ions. This reduction of the 3d moment sets a lower limit (A/sub ..pi..//sup 2/ > .04) on the square of the covalent admixture parameter. The spatial distribution of the delocalized moment has been studied by Fourier techniques which indicate a significant moment density between chromium ions in the chromium layers.

The post-war Middle East  

SciTech Connect

The Middle East remains today the global energy fulcrum. One year after the Persian Gulf war, the region is in greater turmoil and political uncertainty than it has known in modern times. The Iraqi invasion of Kuwait and subsequent external military intervention forced neighboring states to question the need for a foreign military presence in the future. The rift between the secular revolutionary states in the region led by Iraq, Libya, Yemen, Algeria, and Syria and the traditional monarchy of Saudi Arabia and the emirates of the gulf has widened. Egypt provides, at present, an uncomfortable bridge. The balance of political forces may be shifting. This paper attempts to answer the following questions: Where will we see the new leadership in the Middle East Will it again play a role through the Organization of Petroleum Exporting Countries and determination of the oil price in shaping the structure of global energy supply and demand

Geopolitical implications of Middle East oil  

SciTech Connect

Despite the current belief that there is no longer an energy crisis, the U.S. is highly dependent on imported oil from the Middle East. This dependence will increase with economic growth, causing crude imports to double by the year 2000. Without further investment in exploration and development, the U.S. will continue to suffer from a declining reserve base and the uncertainties associated with world politics.

Some Lizards of the Middle West  

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

Lizards of the Middle West Lizards of the Middle West Nature Bulletin No. 344-A May 10, 1969 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation SOME LIZARDS OF THE MIDDLE WEST More than 2,500 kinds of lizards are now known in the world, and they vary more widely in size, shape, color and habit than any of the other three groups of reptiles -- the snakes, the turtles and the alligators. Three kinds of lizards are known to live within 50 miles of Chicago but they are so scarce, and so wary or secretive, that the total number found by all the reptile enthusiasts is often only one or two a year. Farther south they become more common and farm boys know them well. Lizards, having dry scaly skins that they shed from time to time, should not be confused with the salamanders which, altho also four- legged and cold-blooded, are amphibians -- not reptiles -- and have moist smooth skins. The only live lizards that most of us ever see are in the zoos, notably the sluggish Gila Monster which is one of the only two poisonous species; or a friendly little Horned "Toad" which someone may have brought back from the Southwest; or one of those little American chameleons sometimes sold at carnivals or county fairs in states where that is still permitted.

Temperature Dependent Electrical Transport Properties of Ni-Cr and Co-Cr Binary Alloys  

Science Conference Proceedings (OSTI)

The temperature dependent electrical transport properties viz. electrical resistivity and thermal conductivity of Ni{sub 10}Cr{sub 90} and Co{sub 20}Cr{sub 80} alloys are computed at various temperatures. The electrical resistivity has been calculated according to Faber-Ziman model combined with Ashcroft-Langreth partial structure factors. In the present work, to include the ion-electron interaction, we have used a well tested local model potential. For exchange-correlation effects, five different forms of local field correction functions due to Hartree (H), Taylor (T), Ichimaru and Utsumi (IU), Farid et al (F) and Sarkar et al (S) are used. The present results due to S function are in good agreement with the experimental data as compared to results obtained using other four functions. The S functions satisfy compressibility sum rule in long wave length limit more accurately as compared to T, IU and F functions, which may be responsible for better agreement of results, obtained using S function. Also, present result confirms the validity of present approach in determining the transport properties of alloys like Ni-Cr and Co-Cr.

CR mammography: Design and implementation of a quality control program  

SciTech Connect

Despite the recent acquisition of significant quantities of computed radiography CR equipment for mammography, Mexican regulations do not specify the performance requirements for digital systems such as those of CR type. The design of a quality control program QCP specific for CR mammography systems was thus considered relevant. International protocols were taken as reference to define tests, procedures and acceptance criteria. The designed QCP was applied in three CR mammography facilities. Important deficiencies in spatial resolution, noise, image receptor homogeneity, artifacts and breast thickness compensation were detected.

Chemical and electrochemical behavior of the Cr(III)/Cr(II) half cell in the NASA Redox Energy Storage System  

DOE Green Energy (OSTI)

The Cr(III) complexes in the NASA Redox Energy Storage System have been isolated and identified as Cr(H/sub 2/O)/sub 6//sup +3/ and Cr(H/sub 2/O)/sub 5/Cl/sup +2/ by ion-exchange chromatography and visible spectrophotometry. The cell reactions during charge-discharge cycles have been followed by means of visible spectrophotometry. The spectral bands were resolved into component peaks and concentrations calculated using Beer's Law. During the charge mode Cr(H/sub 2/O)/sub 5/Cl/sup +2/ is reduced to Cr(H/sub 2/O)/sub 5/Cl/sup +/ and during the discharge mode Cr(H/sub 2/O)/sub 5/Cl/sup +/ is oxidized back to Cr(H/sub 2/O)/sub 5/Cl/sup +2/. Both electrode reactions occur via a chloride-bridge inner-sphere reaction pathway. Hysteresis effects can be explained by the slow attainment of equilibrium between Cr(H/sub 2/O)/sub 6//sup +3/ and Cr(H/sub 2/O)/sub 5/Cl/sup +2/.

Middle East future line plans muddled following Gulf War  

Science Conference Proceedings (OSTI)

This paper reports that the recent Gulf War has left the middle East in an awkward situation on current and future pipe line projects. Much of Kuwait's production capacity was destroyed and its ability to regain its previous position as an oil producer in the Middle East in the near term is questionable. Iraq's production remains severely curtailed by international agreement. Saudi Arabia and the other Middle Eastern states continue to produce at the higher than normal levels instigated in the early days of the crisis. The continuing efforts to bring the Kuwait oilfields under control, coupled with ongoing excessive production by some Middle eastern countries and the world response to Sadam Hussein's questionable intentions leave the Middle East pipe line construction picture muddled. The war forestalled pipe line projects in Kuwait and Iraq and many of the planned projects now are questionable. In other areas of the Middle East, the war may have firmed tentative plans for pipe line construction.

Oil, turmoil, and Islam in the Middle East  

SciTech Connect

The turmoil and strife of the Middle East raises serious questions about the security of the world's oil supply. The author argues that OPEC and OAPEC can no longer afford to impose indiscriminate price increases on the marketplace because they hurt not only themselves but oil poor Third World nations as well. The author analyzes the importance of Middle Eastern oil in world politics. He emphasizes that any consideration of the forces influencing development in the Middle East should take Islamic tradition into account. Each chapter is organized around a current Middle Eastern problem: oil politics in relation to international energy needs; the ramifications of the new oil wealth and power of the Middle East; The Iran-Iraq War; Muslim insurgency in Afghanistan; The Arab-Israel conflict; turmoil in Lebanon; Palestinian nationalism; and the Middle East as a superpower.

Effect of the magnetic phase transition on the charge transport in layered semiconductor ferromagnets TlCrS{sub 2} and TlCrSe{sub 2}  

Science Conference Proceedings (OSTI)

TlCrS{sub 2} and TlCrSe{sub 2} crystals were synthesized by solid-state reaction. X-ray diffraction analysis showed that TlCrS{sub 2} and TlCrSe{sub 2} compounds crystallize in the hexagonal crystal system with lattice parameters a = 3.538 A, c = 21.962 A, c/a {approx} 6.207, z = 3; a = 3.6999 A, c = 22.6901 A, c/a {approx} 6.133, z = 3; and X-ray densities {rho}{sub x} = 6.705 and 6.209 g/cm{sup 3}, respectively. Magnetic and electric studies in a temperature range of 77-400 K showed that TlCrS{sub 2} and TlCrSe{sub 2} are semiconductor ferromagnets. Rather large deviations of the experimental effective magnetic moment of TlCrS{sub 2} (3.26 {mu}{sub B}) and TlCrSe{sub 2} (3.05 {mu}{sub B}) from the theoretical one (3.85 {mu}{sub B}) are attributed to two-dimensional magnetic ordering in the paramagnetic region of strongly layered ferromagnets TlCrS{sub 2} and TlCrSe{sub 2}. The effect of the magnetic phase's transition on the charge transport in TlCrS{sub 2} and TlCrSe{sub 2} is detected.

Itinerant Antiferromagnetism in BaCr2As2  

SciTech Connect

We report single-crystal synthesis, specific-heat and resistivity measurements and electronic structure calculations for BaCr{sub 2}As{sub 2}. This material is a metal with itinerant antiferromagnetism, similar to the parent phases of Fe-based high-temperature superconductors, but differs in magnetic order. Comparison of bare band-structure density of states and the low-temperature specific heat implies a mass renormalization of {approx}2. BaCr{sub 2}As{sub 2} shows stronger transition-metal-pnictogen covalency than the Fe compounds, and in this respect is more similar to BaMn{sub 2}As{sub 2}. This provides an explanation for the observation that Ni and Co doping is effective in the Fe-based superconductors, but Cr or Mn doping is not.

Nitrate Enhanced Microbial Cr(VI) Reduction-Final Report  

Science Conference Proceedings (OSTI)

A major challenge for the bioremediation of radionuclides (i.e., uranium, technetium) and metals (i.e., Cr(VI), Hg) is the co-occurrence of nitrate as it can inhibit metal transformation. Denitrification (nitrate reduction to dinitrogen gas) is considered the most important ecological process. For many metal and metalloid reducing bacteria, however, ammonia is the end product through respiratory nitrate reduction (RNRA). The focus of this work was to determine how RNRA impacts Cr(VI) transformation. The goal was to elucidate the specific mechanism(s) that limits Cr(VI) reduction in the presence of nitrate and to use this information to develop strategies that enhance Cr(VI) reduction (and thus detoxification). Our central hypothesis is that nitrate impacts the biotransformation of metals and metalloids in three ways 1) as a competitive alternative electron acceptor (inhibiting transformation), 2) as a co-metabolite (i.e., concomitant reduction, stimulating transformation), and 3) as an inducer of specific proteins and pathways involved in oxidation/reduction reactions (stimulating transformation). We have identified three model organisms, Geobacter metallireducens (mechanism 1), Sulfurospirillum barnesii, (mechasism 2), and Desulfovibrio desulfuricans (mechanisms 3). Our specific aims were to 1) investigate the role of Cr(VI) concentration on the kinetics of both growth and reduction of nitrate, nitrite, and Cr(VI) in these three organisms; 2) develop a profile of bacterial enzymes involved in nitrate transformation (e.g., oxidoreductases) using a proteomic approach; 3) investigate the function of periplasmic nitrite reductase (Nrf) as a chromate reductase; and 4) develop a strategy to maximize microbial chromium reduction in the presence of nitrate. We found that growth on nitrate by G. metallireducens was inhibited by Cr(VI). Over 240 proteins were identified by LC/MS-MS. Redox active proteins, outer membrane heavy metal efflux proteins, and chemotaxis sensory proteins (Gmet_2478 and Gmet_1641) were up-regulated with exposure to Cr(VI). A nine-heme cytochrome C was purified that could reduce nitrite and could be oxidized by Cr(VI). For D. desulfuricans, we found that confirmed that Cr(VI) induced a prolonged lag period when Cr(VI) was reduced. Over three hundred proteins were unequivocally identified by LC/MS-MS and a significant number of down-regulated proteins for which the levels were changed >2 fold compared to control. Sulfite reductase levels were similar, however, nitrate and nitrite reductase were down-regulated. The supernatant of spent cultures was found to contain a filterable, heat stable compound that rapidly reduced Cr(VI). In addition, desulfoviridin was purified from nitrate grown cells and shown to have nitrite reductase activity that was inhibited by Cr(VI). For S. barnesii, periplasmic nitrate reductase (Nap), nitrite reductase (Nrf), and the metalloid reductase (Rar) were purified and characterized. The supernatant of spent cultures was also found to contain a filterable, heat stable compound that rapidly reduced Cr(VI) but that Rar also reduced Cr(VI). Our results from specific aims 1 through 3 indicate that for G. metallireducens, Cr(VI) inhibits nitrate respiration as it oxidizes cytochromes involved in nitrate respiration. Iron reduction is apparently not affected and the inhibitory affects of Cr(VI) may be attenuated by the addition of sufficient Fe(III) to generate Fe(II) that abiotically reduces the chromium. For S. barnesii, although the enzyme assays indicate that the components of the respiratory pathway for nitrate (e.g. Nap and Nrf) are inhibited by chromate, the organism has a mechanism to prevent this from actually occurring. Our current hypothesis is that the non-specific metalloid reductase (Rar) is providing resistance by reducing the Cr(VI). The strategy here would be to enhance its growth and metabolism in the natural setting. Lactate is a suitable electron donor for S. barnesii but other donors are possible. Although the version of the Phylochip used for monitoring the microb

Delivering Energy Efficiency to Middle Income Single Family Households Delivering Energy Efficiency to Middle Income Single Family Households Title Delivering Energy Efficiency to Middle Income Single Family Households Publication Type Report Year of Publication 2011 Authors Zimring, Mark, Merrian Borgeson, Ian M. Hoffman, Charles A. Goldman, Elizabeth Stuart, Annika Todd, and Megan A. Billingsley Pagination 102 Date Published 12/2011 Publisher LBNL City Berkeley Keywords electricity markets and policy group, energy analysis and environmental impacts department Abstract The question posed in this report is: How can programs motivate these middle income single family households to seek out more comprehensive energy upgrades, and empower them to do so? Research methods included interviews with more than 35 program administrators, policy makers, researchers, and other experts; case studies of programs, based on interviews with staff and a review of program materials and data; and analysis of relevant data sources and existing research on demographics, the financial status of Americans, and the characteristics of middle income American households. While there is no 'silver bullet' to help these households overcome the range of barriers they face, this report describes outreach strategies, innovative program designs, and financing tools that show promise in increasing the attractiveness and accessibility of energy efficiency for this group. These strategies and tools should be seen as models that are currently being honed to build our knowledge and capacity to deliver energy improvements to middle income households. However, the strategies described in this report are probably not sufficient, in the absence of robust policy frameworks, to deliver these improvements at scale. Instead, these strategies must be paired with enabling and complementary policies to reach their full potential.

Diminishing importance of Middle East oil: its future implications. [Monograph  

Science Conference Proceedings (OSTI)

Long-term structural changes in the oil and energy markets and the reduced dependence of oil importers on Middle East production are the result of better energy-use efficiency, fuel substitution, and an increase in OPEC production. The decision by western countries to lower their demand and reduce stockpiles has had a significant impact on oil-exporting countries in terms of their spending, their economic development, and their aid programs. Political events and disruptions have also affected the Middle East's political, strategic, and economic future. (DCK)

Cr/sup 3 +/-doped colquiriite solid state laser material  

DOE Patents (OSTI)

Chromium doped colquiriite, LiCaAlF/sub 6/:Cr/sup 3 +/, is useful as a tunable laser crystal that has a high intrinsic slope efficiency, comparable to or exceeding that of alexandrite, the current leading performer of vibronic sideband Cr/sup 3 +/ lasers. The laser output is tunable from at least 720 nm to 840 nm with a measured slope efficiency of about 60% in a Kr laser pumped laser configuration. The intrinsic slope efficiency (in the limit of large output coupling) may approach the quantum defect limited value of 83%. The high slope efficiency implies that excited state absorption (ESA) is negligible. The potential for efficiency and the tuning range of this material satisfy the requirements for a pump laser for a high density storage medium incorporating Nd/sup 3 +/ or Tm/sup 3 +/ for use in a multimegajoule single shot fusion research facility. 4 figs.

Cr{sub 2}Nb-based alloy development  

SciTech Connect

This paper summarizes recent progress in developing Cr{sub 2}Nb/Cr(Nb) alloys for structural use in advanced fossil energy conversion systems. Alloy additions were added to control the microstructure and mechanical properties. Two beneficial elements have been identified among all alloying additions added to the alloys. One element is effective in refining the coarse eutectic structure and thus substantially improves the compressive strength and ductility of the alloys. The other element enhances oxidation resistance without sacrificing the ductility. The tensile properties are sensitive to cast defects, which can not be effectively reduced by HIPping at 1450-1580{degrees}C and/or directionally solidifying via a floating zone remelting method.

Cooperative monitoring workshop: Focus on the Middle East  

SciTech Connect

Sandia National Laboratories and the Institute for Global Conflict and Cooperation hosted a workshop on the application of cooperative monitoring to the Middle East. The workshop, held in Albuquerque, New Mexico, from July 17 through 21, 1994, was sponsored by the US Department of Energy, the Arms Control and Disarmament Agency, and the US Department of State. The meeting, which focused on use of technical monitoring tools and sharing of collected information to facilitate regional agreements, included participants from five regional countries as well as from American universities, the US government, and US National Laboratories. Some attendees previously participated in meetings of the Arms Control and Regional Security working group of the Middle East Multilateral Peace Talks. The workshop combined presentations, demonstrations and hands-on experimentation with monitoring hardware and software. An exercise was conducted to evaluate and recommend cooperative monitoring options for a model agreement between two hypothetical countries. Historical precedents were reviewed and the role of environmental and natural resource conflicts explored. These activities were supplemented by roundtable discussions covering Middle East security issues, the relationship of ``national means`` to cooperative monitoring, and cooperative monitoring of ballistic missiles in the Middle East.

Oil and turmoil: America faces OPEC and the Middle East  

Science Conference Proceedings (OSTI)

Middle-East expert Rustow traces the chain of events that placed economic power in an unstable region. He recounts how European imperialists acquired and surrendered their positions of domination, how nationalists such as Nasser and Qaddafi sought to manipulate the superpowers, and how leaders such as Sadat and Begin wrestled with war and peace. Meanwhile, the oil industry's Seven Sisters lost their preeminence as OPEC grew from a loose confederacy of oil shiekdoms into a cartel strong enough to shake the world economy. Rustow analyzes the confusion in oil-consuming countries that led to long gasoline lines one year and talk of an oil glut and OPEC's collapse the next. He puts into context Washington's uneven efforts to bring stability to the strife-torn Middle East. 221 references, 3 figures, 7 tables.

In search of an oasis: Opportunity in the Middle East  

SciTech Connect

Across the Middle East, people contend with heat, dust, lack of rainfall, and a harsh geography. In this century, industrial development, political upheaval, and war have left a legacy of environmental and health problems. Scarce arable land is being lost to desertification. Fresh water is diverted, misused, and polluted with hazardous wastes, sewage, and agricultural and other chemicals. Coastal zones are polluted with oil, threatening pristine coral reefs, wild fowl, and fishing areas. Unprecedented urbanization and migration of traditionally rural peoples and resettlement of political refugees and foreign workers strain city services. Yet there is reason for optimism in the Middle East. Peace in the region is in sight, bringing an opportunity to stop the rapid environmental decline. Technology is available to assess the degradation, and the impact of environmental conditions on human health can be quantified.

OPEC Middle East plans for rising world demand amid uncertainty  

Science Conference Proceedings (OSTI)

The Middle Eastern members of the Organization of Petroleum Exporting Countries must plan for huge increases in oil production capacity yet wonder whether markets for the new output will develop as expected. With worldwide oil consumption rising and non-OPEC output likely to reach its resource limits soon, OPEC member countries face major gains in demand for their crude oil. To meet the demand growth, those with untapped resources will have to invest heavily in production capacity. Most OPEC members with such resources are in the Middle East. But financing the capacity investments remains a challenge. Some OPEC members have opened up to foreign equity participation in production projects, and others may eventually do so as financial pressures grow. That means additions to the opportunities now available to international companies in the Middle East. Uncertainties, however, hamper planning and worry OPEC. Chief among them are taxation and environmental policies of consuming-nation governments. This paper reviews these concerns and provides data on production, pricing, capital investment histories and revenues.

Improved oxidation sulfidation resistance of Fe-Cr-Ni alloys  

DOE Patents (OSTI)

High temperature resistance of Fe-Cr-Ni alloy compositions to oxidative and/or sulfidative conditions is provided by the incorporation of about 1 to 8 wt % of Zr or Nb and results in a two-phase composition having an alloy matrix as the first phase and a fine grained intermetallic composition as the second phase. The presence and location of the intermetallic composition between grains of the matrix provides mechanical strength, enhanced surface scale adhesion, and resistance to corrosive attack between grains of the alloy matrix at temperatures of 500 to 1000/sup 0/C.

The response of CR-39 nuclear track detector to 1-9 MeV protons  

SciTech Connect

The response of CR-39 nuclear track detector (TasTrak) to protons in the energy range of 0.92-9.28 MeV has been studied. Previous studies of the CR-39 response to protons have been extended by examining the piece-to-piece variability in addition to the effects of etch time and etchant temperature; it is shown that the shape of the CR-39 response curve to protons can vary from piece-to-piece. Effects due to the age of CR-39 have also been studied using 5.5 MeV alpha particles over a 5-year period. Track diameters were found to degrade with the age of the CR-39 itself rather than the age of the tracks, consistent with previous studies utilizing different CR-39 over shorter time periods.

Phase Diagram of CuCrO2 in a Magnetic Field  

SciTech Connect

The magnetic phase diagram of CuCrO2 is constructed as a function of magnetic field and anisotropy using a trial spin state built from harmonics of a fundamental ordering wavevector. Whereas the multiferroic phase of CuCrO2 is a modified spin spiral with a 3-sublattice (SL) period, the phase diagram also contains 1-SL, 2-SL, 4-SL, and 5-SL collinear states which may be accessi- ble in the nonstoichiometric compound CuCrO2+ . For small anisotropy, CuCrO2 is predicted to undergo a transition between two modified spiral states with an intervening 3-SL collinear phase.

The hydrogen embrittlement of Ni-Cr-Fe alloys  

Science Conference Proceedings (OSTI)

It has been proposed that the stress corrosion cracking (SCC) of nickel-based alloys in low-temperature hydrogenated water is due to hydrogen embrittlement. The purpose of this work was to investigate the role of chromium on hydrogen embrittlement of Ni-Cr-Fe alloys and thus develop a better understanding of the low-temperature SCC phenomenon. The effect of chromium on the hydrogen embrittlement was examined using tensile tests followed by material evaluation via scanning electron microscopy and light optical microscopy. Four alloys were prepared with chromium contents ranging from 6 wt. percent to 35 wt. percent. In the noncharged condition, ductility, as measured by the percent elongation or reduction in area, increased as the alloy chromium content increased. Hydrogen appeared to have only minor effects on the mechanical properties of the low chromium alloys. The addition of hydrogen had a marked effect on the ductility of the higher chromium alloys. In the 26% chromium alloy, the elongation to failure was reduced from 53% to 14% with a change in fracture mode from ductile dimple to intergranular failure. A maximum in embrittlement was observed in the 26% Cr alloy. The maximum in embrittlement coincided with the minimum in stacking-fault energy. It is proposed that the increased hydrogen embrittlement in the high-chromium alloys is due to increased slip planarity caused by the low stacking-fault energy. Slip planarity did not appear to affect the fracture of the noncharged specimens.

The band structure-matched and highly spin-polarized Co{sub 2}CrZ/Cu{sub 2}CrAl Heusler alloys interface  

Science Conference Proceedings (OSTI)

Here we present a lattice- and band-matched nonmagnetic L21 Heusler alloy spacer for Co{sub 2}CrZ Heusler alloys where Z=Si or Al. By first principle calculations, we find that the band structure matching is almost perfectly satisfied when they are interfaced with Cu{sub 2}CrAl. Despite the loss of half-metallicity due to interface states, our calculations show that the spin polarization at these band-matched (001) interfaces is higher than 80%. These lattice-matched Co{sub 2}CrZ/Cu{sub 2}CrAl interfaces with excellent band matching and enhanced spin scattering asymmetry are promising for all-metallic current-perpendicular-to-plane giant magnetoresistance device applications.

Oil and gas developments in Middle East in 1984  

Science Conference Proceedings (OSTI)

Petroleum production in Middle East countries during 1984 totaled 4,088,853,000 bbl (an average rate of 11,144,407 BOPD), down less than 1.0% from the revised total of 4,112,116,000 bbl produced in 1983. Iraq, Kuwait, Qatar, and Oman had significant increases; Iran and Dubai had significant decreases. Jordan produced oil, although a minor amount, for the first time ever, and new production facilities were in the planning stage in Syria, North Yemen, and Oman, which will bring new fields on stream when completed.

Structure determination of thermal-spray materials using synchrotron x-ray microtomography. [Cr[sub 3]C[sub 2]/NiCr thermal-spray coating  

SciTech Connect

The structure of materials prepared using thermal spray methods is difficult to determine using conventional microscopy of porosimetry methods. The difficulties inherent in these approaches can be circumvented using synchrotron computed microtomography(CMT). An example of the use of CMT to produce a high resolution non- destructive image of a thermal-spray coating is Cr[sub 3]C[sub 2]/NiCr is described here to illustrate the power of this technique.

Combined electrochemical/surface science investigations of Pt/Cr alloy electrodes  

DOE Green Energy (OSTI)

Chromium addition improves the performance of carbon-supported Pt electrodes for oxygen reduction in phosphoric acid fuel cells. To clarify the role of chromium and its chemical nature at the electrode surface, we have performed a combined electrochemical/surface science investigation of a series of bulk Pt/sub x/Cr/sub (1-x)/ alloys (0 less than or equal to x less than or equal to 1). In this paper we report the surface characterization of the starting electrodes by XPS, electrochemical results from cyclic voltammetry in 85% phosphoric acid, and post-electrochemical surface characterization. For Cr contents less than 40%, the electrodes were quite stable up to +1.6 V vs DHE. The surface Cr was largely oxidized to Cr/sup +3/ for surfaces at open circuit ad those exposed at potentials < +1.4 V. For intermediate Cr levels, Cr was leached from the surface region by +1.5 V, leaving a porous Pt electrode with increased electrochemical hydrogen adsorption capacity. For Pt/sub 0.2//Cr/sub 0.8/, treatments at +1.4 V and above led to the appearance of Pt/sup 4 +/ and Cr/sup 6 +/ species, apparently stabilized in a porous phosphate overlayer up to 50 A thick. The Pt electrochemical hydrogen adsorption capacity was simultaneously increased by a factor of 15. 18 refs., 4 figs.

Design and performance of a multiterawatt Cr:LiSrAlF[sub 6] laser system  

Science Conference Proceedings (OSTI)

We have developed a compact, flash-lamp-pumped Cr:LiSrAlF[sub 6] (Cr:LiSAF) laser system capable of producing femtosecond pulses exhibiting peak powers greater than 2 TW. Chirped pulse amplification in a Cr:LiSAF regenerative amplifier produces 15-mJ pulses at a 5-Hz repetition rate. Further amplification in Cr:LiSAF yields recompressed pulse energies of 280 mJ and a pulse duration of less than 135 fs at a 1.0-Hz repetition rate. We describe the design and performance of this laser as well as the optimization of chirped pulse amplification in flash-lamp-pumped Cr:LiSAF.

Mesoporous carbon -Cr2O3 composite as an anode material for lithium ion batteries  

SciTech Connect

Mesoporous carbon-Cr2O3 (M-C-Cr2O3) composite was prepared by co-assembly of in-situ formed phenolic resin, chromium precursor, and Pluronic block copolymer under acidic conditions, followed by carbonization at 750oC under Argon. The TEM results confirmed that the Cr2O3 nanoparticles, ranging from 10 to 20 nm, were well dispersed in the matrix of mesoporous carbon. The composite exhibited an initial reversible capacity of 710 mAh g-1 and good cycling stability, which is mainly due to the synergic effects of carbons within the composites, i.e. confining the crystal growth of Cr2O3 during the high temperature treatment step and buffering the volume change of Cr2O3 during the cycling step. This composite material is a promising anode material for lithium ion batteries.

Petroleum production in Middle East countries during 1987 totaled an estimated 4,500,500,000 bbl (an average rate of 12,330,137 b/d), up slightly from the revised 1986 total of 4,478,972,000 bbl. Iran, Iraq, Syria, and Yemen Arab Republic had significant increases; Kuwait and Saudi Arabia had significant decreases. Production was established for the first time in People's Democratic Republic of Yemen. New fields went on production in Iraq, Oman, People's Democratic Republic of Yemen, and Syria, and significant oil discoveries were reported in Iraq, Oman, People's Democratic Republic of Yemen, Syria, and Yemen Arab Republic. The level of exploration increased in 1987 with new concessions awarded in some countries, drilling and seismic activities on the increase, new regions in mature areas explored for the first time, and significant reserve additions reported in new and old permits. The Iraq-Iran war still had a negative impact in some regions of the Middle East, particularly in and around the Gulf. 11 figs., 4 tabs.

Effect of Corruption on Tax Revenues in the Middle East  

E-Print Network (OSTI)

This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the authors and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the authors and are published to elicit comments and to further debate. This study estimates the impact of corruption on the revenue-generating capacity of different tax categories in the Middle East. We find that the low revenue collection as a share of GDP there compared to other middle-income regions is due in part to corruption, and certain taxes are more affected than others. Taxes that require frequent interaction between the tax authority and individuals, such as taxes on international trade, seem to be more affected by corruption than most other types of taxation. This suggests that if governments need to raise more tax revenues in a way that minimizes distortions and maximizes social welfare, they should implement reforms that either reduce corruption or raise revenues from tax categories that are less susceptible to corruption. Possible reforms of the revenue system and

Thermodynamic Modeling and Experimental Study of the Fe-Cr-Zr System  

Science Conference Proceedings (OSTI)

Wide applications of zircaloys, stainless steels and their interactions in nuclear reactors require the knowledge on phase stability and thermodynamic property of the Fe-Cr-Zr system. This knowledge is also important to develop new Zr-contained Fe-Cr ferritic steels. This work aims at developing thermodynamic models for describing phase stability and thermodynamic property of the Fe-Cr-Zr system using the Calphad approach coupled with experimental study. Thermodynamic descriptions of the Fe-Cr and Cr-Zr systems were either directly adopted or slightly modified from literature. The Fe-Zr system has been remodeled to accommodate recent ab-initio calculation of formation enthalpies of various Fe-Zr compounds. Reliable ternary experimental data and thermodynamic models were mainly available in the Zr-rich region. Therefore, selected ternary alloys located in the vicinity of the eutectic valley of (Fe,Cr,Zr) and (Fe,Cr)2Zr laves phase in the Fe-rich region have been experimentally investigated in this study. Microstructure has been examined by using scanning electron microscope, energy-dispersive Xray spectroscopy and X-ray diffraction. These experimental results, along with the literature data were then used to develop thermodynamic models for phases in the Fe-Cr-Zr system. Calculated phase equilibria and thermodynamic properties of the ternary system yield satisfactory agreements with available experimental data, which gives the confidence to use these models as building blocks for developing a Zr, Fe and Cr contained multicomponent thermodynamic database for broader applications in nuclear reactors.

The effects of the middle school concept on student achievement as identified by principals and the Academic Excellence Indicator System (AEIS) reports in selected middle schools in Texas  

E-Print Network (OSTI)

The purpose of this study was to investigate the possible relationship between the level of implementation of the middle school concept and student achievement. The level of implementation of the middle school concept was determined by the Texas Assessment of Middle Level Schools (TAMLS) which was completed by a random sample of middle school principals from across Texas. Student achievement and selected demographic data were obtained from the Academic Excellence Indicator System (AEIS) reports on the various campuses as published on the Texas Education Agency (TEA, 2003a) website. Student achievement, school size, and demographic variables were investigated using frequency counts, mean scores, standard deviations, analysis of variance (ANOVA), and Pearson product?moment correlations across independent variable categories. The independent variable categories were the five criteria and the total score as rated by principals on the TAMLS survey. Major research findings of this study include: 1. Relationships were found between the TAMLS criteria of developmental responsiveness and teacher preparation and professional development with student achievement across all of the research questions examined. 2. Relationships were found between school size, the TAMLS criteria and student achievement. 3. Relationships were found between student ethnicity, the TAMLS criteria, and student achievement. The study results with regard to the relationship between the level of implementation of the middle school concept, taken in its totality, are inconclusive. This finding is supported in a review of the literature. Based on the findings of the study, researcher recommendations include: 1. Middle schools involved in reform efforts to improve student achievement should focus their efforts in the areas of developmental responsiveness and teacher professional development. 2. Principals of large middle schools (n ? 801 students) should consider the implementation of the middle school concept as a design strategy when reform efforts are undertaken.

Steamside Oxidation Behavior of Experimental 9%Cr Steels  

SciTech Connect

Reducing emissions and increasing economic competitiveness require more efficient steam power plants that utilize fossil fuels. One of the major challenges in designing these plants is the availability of materials that can stand the supercritical and ultra-supercritical steam conditions at a competitive cost. There are several programs around the world developing new ferritic and austenitic steels for superheater and reheater tubes exposed to the advanced steam conditions. The new steels must possess properties better than current steels in terms of creep strength, steamside oxidation resistance, fireside corrosion resistance, and thermal fatigue resistance. This paper introduces a series of experimental 9%Cr steels containing Cu, Co, and Ti. Stability of the phases in the new steels is discussed and compared to the phases in the commercially available materials. The steels were tested under both the dry and moist conditions at 650C for their cyclical oxidation resistance. Results of oxidation tests are presented. Under the moist conditions, the experimental steels exhibited significantly less mass gain compared to the commercial P91 steel. Microstructural characterization of the scale revealed different oxide compositions.

Remediation of Cr(VI) by biogenic magnetic nanoparticles: An x-ray magnetic circular dichroism study  

SciTech Connect

Biologically synthesized magnetite (Fe{sub 3}O{sub 4}) nanoparticles are studied using x-ray absorption and x-ray magnetic circular dichroism following exposure to hexavalent Cr solution. By examining their magnetic state, Cr cations are shown to exist in trivalent form on octahedral sites within the magnetite spinel surface. The possibility of reducing toxic Cr(VI) into a stable, non-toxic form, such as a Cr{sup 3+}-spinel layer, makes biogenic magnetite nanoparticles an attractive candidate for Cr remediation.

Optimizing Cr(VI) and Tc(VII) remediation through nano-scale biomineral engineering  

Science Conference Proceedings (OSTI)

To optimize the production of biomagnetite for the bioremediation of metal oxyanion contaminated waters, the reduction of aqueous Cr(VI) to Cr(III) by two biogenic magnetites and a synthetic magnetite was evaluated under batch and continuous flow conditions. Results indicate that nano-scale biogenic magnetite produced by incubating synthetic schwertmannite powder in cell suspensions of Geobacter sulfurreducens is more efficient at reducing Cr(VI) than either biogenic nano-magnetite produced from a suspension of ferrihydrite 'gel' or synthetic nano-scale Fe{sub 3}O{sub 4} powder. Although X-ray Photoelectron Spectroscopy (XPS) measurements obtained from post-exposure magnetite samples reveal that both Cr(III) and Cr(VI) are associated with nanoparticle surfaces, X-ray Magnetic Circular Dichroism (XMCD) studies indicate that some Cr(III) has replaced octahedrally coordinated Fe in the lattice of the magnetite. Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) measurements of total aqueous Cr in the associated solution phase indicated that, although the majority of Cr(III) was incorporated within or adsorbed to the magnetite samples, a proportion ({approx}10-15 %) was released back into solution. Studies of Tc(VII) uptake by magnetites produced via the different synthesis routes also revealed significant differences between them as regards effectiveness for remediation. In addition, column studies using a {gamma}-camera to obtain real time images of a {sup 99m}Tc(VII) radiotracer were performed to visualize directly the relative performances of the magnetite sorbents against ultra-trace concentrations of metal oxyanion contaminants. Again, the magnetite produced from schwertmannite proved capable of retaining more ({approx}20%) {sup 99m}Tc(VII) than the magnetite produced from ferrihydrite, confirming that biomagnetite production for efficient environmental remediation can be fine-tuned through careful selection of the initial Fe(III) mineral substrate supplied to Fe(III)-reducing bacteria.

Oxidation behavior of arc evaporated Al-Cr-Si-N thin films  

SciTech Connect

The impact of Al and Si on the oxidation behavior of Al-Cr-(Si)-N thin films synthesized by arc evaporation of powder metallurgically prepared Al{sub x}Cr{sub 1-x} targets with x = Al/(Al + Cr) of 0.5, 0.6, and 0.7 and (Al{sub 0.5}Cr{sub 0.5}){sub 1-z}Si{sub z} targets with Si contents of z = 0.05, 0.1, and 0.2 in N{sub 2} atmosphere was studied in detail by means of differential scanning calorimetry, thermogravimetric analysis (TGA), x-ray diffraction, and Raman spectroscopy. Dynamical measurements in synthetic air (up to 1440 Degree-Sign C) revealed the highest onset temperature of pronounced oxidation for nitride coatings prepared from the Al{sub 0.4}Cr{sub 0.4}Si{sub 0.2} target. Isothermal TGA at 1100, 1200, 1250, and 1300 Degree-Sign C highlight the pronounced improvement of the oxidation resistance of Al{sub x}Cr{sub 1-x}N coatings by the addition of Si. The results show that Si promotes the formation of a dense coating morphology as well as a dense oxide scale when exposed to air.

Processing of LaCrO{sub 3} for solid oxide fuel cell applications  

DOE Green Energy (OSTI)

The University of Missouri-Rolla is performing a 5 year research program dedicated towards the development of LaCrO{sub 3}-based interconnect powders which densify when in contact with anode and cathode materials for solid oxide fuel cells (SOFC). During the course of this program the authors investigated compositions within the pseudo-ternary LaCrO{sub 3}-LaMnO{sub 3}-LaCoO{sub 3} system. Their expanded studies on the processing and sintering of LaCrO{sub 3} to make dense interconnects using LaCrO{sub 3}-based oxides at temperatures less than 1,500 C in an air atmosphere and in contact with both anode and cathode oxides. The specific objectives of this research program are to: Develop a novel technique which reproducibly yields LaCrO{sub 3}-based powders with the desired particle characteristics; Fully understand the liquid phase sintering mechanism; Clearly identify the reason why LaCrO{sub 3} does not densify in the presence of electrolyte and cathode materials; Systematically solve this problem through judicious control over the liquid phase; and Incorporate materials developed in this program into planar cells and measure their performance. Results are discussed on porosity and skrinkage, and sintering and melting behaviors.

Leaching Behavior of Cr(III) in Stabilized/Solidified Soil  

Science Conference Proceedings (OSTI)

The leaching behavior of chromium was studied using batch leaching tests, surface complexation modeling and X-ray absorption near edge structure (XANES) spectroscopy. A contaminated soil sample containing 1330 mg-Cr kg{sup -1} and 25 600 mg-Fe kg{sup -1} of dry soil was stabilized/solidified (S/S) with 10% cement, 25% cement, 10% lime and a mixture of 20% flyash and 5% lime. The XANES analysis showed that Cr(III) was the only Cr species in untreated soil and S/S-treated samples. The leachate Cr concentration determined using the toxicity characteristic leaching procedure (TCLP) was reduced from 5.18 mg l{sup -1} for untreated soil to 0.84 mg l{sup -1} for the sample treated with 25% cement. The Cr leachability in untreated and treated soil samples decreased dramatically as the pH increased from 3 to 5, remained at similar levels in the pH range between 5 and 10.5, and further decreased at pH > 10.5. Modeling results indicated that the release of Cr(III) was controlled by adsorption on iron oxides at pH 10.5.

Dominant Middle East oil reserves critically important to world supply  

Science Conference Proceedings (OSTI)

This paper reports that the location production, and transportation of the 60 million bbl of oil consumed in the world each day is of vital importance to relations between nations, as well as to their economic wellbeing. Oil has frequently been a decisive factor in the determination of foreign policy. The war in the Persian Gulf, while a dramatic example of the critical importance of oil, is just the latest of a long line of oil-influenced diplomatic/military incidents, which may be expected to continue. Assuming that the world's remaining oil was evenly distributed and demand did not grow, if exploration and development proceeded as efficiently as they have in the U.S., world oil production could be sustained at around current levels to about the middle of the next century. It then would begin a long decline in response to a depleting resource base. However, the world's remaining oil is very unevenly distributed. It is located primarily in the Eastern Hemisphere, mostly in the Persian Gulf, and much is controlled by the Organization of Petroleum Exporting Countries. Scientific resource assessments indicate that about half of the world's remaining conventionally recoverable crude oil resource occurs in the Persian Gulf area. In terms of proved reserves (known recoverable oil), the Persian Gulf portion increase to almost two-thirds.

Middle-Late Permian mass extinction on land  

Science Conference Proceedings (OSTI)

The end-Permian mass extinction has been envisaged as the nadir of biodiversity decline due to increasing volcanic gas emissions over some 9 million years. We propose a different tempo and mechanism of extinction because we recognize two separate but geologically abrupt mass extinctions on land, one terminating the Middle Permian (Guadalupian) at 260.4 Ma and a later one ending the Permian Period at 251 Ma. Our evidence comes from new paleobotanical, paleopedological, and carbon isotopic studies of Portal Mountain, Antarctica, and comparable studies in the Karoo Basin, South Africa. Extinctions have long been apparent among marine invertebrates at both the end of the Guadalupian and end of the Permian, which were also times of warm-wet greenhouse climatic transients, marked soil erosion, transition from high- to low-sinuosity and braided streams, soil stagnation in wetlands, and profound negative carbon isotope anomalies. Both mass extinctions may have resulted from catastrophic methane outbursts to the atmosphere from coal intruded by feeder dikes to flood basalts, such as the end-Guadalupian Emeishan Basalt and end-Permian Siberian Traps.

Photochemistry of Methyl Bromide on the ?-Cr2O3(0001) Surface  

Science Conference Proceedings (OSTI)

The photochemical properties of the Cr-terminated ?-Cr2O3(0001) surface were explored using methyl bromide (CH3Br) as a probe molecule. CH3Br adsorbed and desorbed molecularly from the Cr-terminated ?-Cr2O3(0001) surface without detectable thermal decomposition. Temperature programmed desorption (TPD) revealed a CH3Br desorption state at 240 K for coverages up to 0.5 ML, followed by more weakly bound molecules desorbing at 175 K for coverages up to 1 ML. Multilayer exposures led to desorption at ~130 K. The CH3Br sticking coefficient was unity at 105 K for coverages up to monolayer saturation, but decreased as the multilayer formed. In contrast, pre-oxidation of the surface (using an oxygen plasma source) led to capping of surface Cr3+ sites and near complete removal of CH3Br TPD states above 150 K. The photochemistry of chemisorbed CH3Br was explored on the Cr-terminated surface using post-irradiation TPD and photon stimulated desorption (PSD). Irradiation of adsorbed CH3Br with broad band light from a Hg arc lamp resulted in both photodesorption and photodecomposition of the parent molecule at a combined cross section of ~10-22 cm2. Parent PSD was indicative of molecular photodesorption, but CH3 was also detected in PSD and Br atoms were left on the surface, both reflective of photo-induced CH3-Br bond dissociation. Use of a 385 nm cut-off filter effectively shut down the photodissociation pathway but not the parent molecule photodesorption process. From these observations it is inferred that d-to-d transitions in ?-Cr2O3, occurring at photon energies <3 eV, are not responsible for photodecomposition of 2 adsorbed CH3Br. It is unclear to what extent band-to-band versus direct CH3Br photolysis play in CH3-Br bond dissociation initiated by more energetic photons.

Middle East, North Africa And Western Eurasia Seismic Research Database  

E-Print Network (OSTI)

The National Nuclear Security Administration (NNSA) Ground-Based Nuclear Explosion Monitoring Research and Engineering (GNEM R&E) Program has made significant progress populating a comprehensive Seismic Research Database (SRDB) used for deriving seismic calibration parameters for the Middle East, North Africa and Western Eurasia (ME/NA/WE) regions. In addition to an overview of select individual information products, we present an overview of our visualization, integration, validation, and organizational processes. Development of these processes and the SRDB was necessitated by both the very large amount of data and information involved (over 2 terabytes) and the varied data and research result formats utilized. The SRDB allows for the collection of raw and contextual seismic data used in research, provides an interface for researchers to access data, provides a framework to store research results and integrate data sets, and supports assembly, integration and dissemination of data sets to the NNSA Knowledge Base (KB). The SRDB is a flexible and extensible framework consisting of a relational database (RDB), Geographical Information System (GIS), and associated product/data visualization and data management tools. This framework is designed to accommodate large volumes of data in diverse formats from many sources (both in-house-derived research and integrated products), in addition to maintaining detailed quality control and metadata. In order to efficiently organize information within the SRDB, it was necessary to automate procedures needed to create and update database tables, but a large effort is still required by technicians and scientists to load special data sets, review results of automated processing and resolve quality issues. The SRDB currently has 3 million ...

Integrated Investigation on the Production and Fate of Organo-Cr(III) Complexes from Microbial Reduction of Chromate  

DOE Green Energy (OSTI)

Our objective is to investigate the complexity of chromium biogeocycling. Our results clearly support more complexity. In short, the chromium cycle is not as simple as the conversion between Cr(III) and Cr(VI) in inorganic forms. We have obtained more evidence to prove the formation of soluble organo-Cr(III) complexes from microbial reduction of Cr(VI). The complexes are relatively stable due to the slow ligand exchange of Cr(III). However, some microorganisms can consume the organic ligands and release Cr(III), which then precipitates. Efforts are being made to characterize the organo-Cr(III) complexes and investigate their behavior in soil. Progress and efforts are summarized for each task. Task 1. Production of soluble organo-Cr(III) complexes by selected microorganisms A total of eight organisms were screened for production of soluble organo-Cr(III) complexes by culturing in both growth and non growth media containing 4 mg/L of Cr(VI); three were Gram positive and five were Gram negative. The Gram-positive bacteria were Cellulomonas sp. ES 6, Rhodococcus sp., and Leafsonia sp., while Shewanella oneidensis MR 1, Desulfovibrio desulfuricans G20, D. vulgaris Hildenborough, Pseudomonas putida MK 1 and Ps. aeruginosa PAO 1 were Gram negative. Purifications of the soluble organo-Cr(III) complexes produced by Cellulomonas sp. ES 6, Shewanella. oneidensis MR 1, Rhodococcus sp., and D. vulgaris Hildenborough were carried out. The culture supernatants were lyophilized and extracted first with methanol followed by water. The extracts were then analyzed for soluble Cr. The majority of the Cr(III) was present in the water-soluble fraction for all of the bacteria tested (data not shown), revealing a general phenomenon of soluble Cr(III) production. Cellulomonas sp. ES6 produced the highest amount of soluble Cr(III) (364 ppm) and D. vulgaris Hildenborough produced the least (143 ppm). Seventy eight percent of the soluble Cr(III) produced by Shewanella. oneidensis MR 1 was water soluble, while 45% was water soluble for the Cellulomonas sp. ES6. The water-soluble fractions were further purified by anion exchange chromatography. All soluble Cr(III) was bound to the anion exchange column. The bound organo-Cr(III) was eluted by gradient elution, (0.25M-2M) using ammonium acetate. Preliminary characterization confirmed the nature of organo-Cr(III) complexes. Further characterization of these species by electrospray ionization mass spectrometry (ESI-MS) is in progress. Task 2. Demonstrate that chromate reduction produces organo-Cr(III) complexes with microbial cellular components. In the past year, further research on the formation of organo-Cr(III) complexes has been completed. Formation of soluble complexes with cell free extracts as the organic portion has resulted in the formation of organo-Cr(III) complexes, approximately 27% Cr(III) remained soluble after 14 days. In addition, complexes formed between individual organic components and Cr(III) have been tested for changes in solubility due to changes in pH.

Synthesis of Room-Temperature Ferromagnetic Cr-doped TiO?(110) Rutile Single Crystals using Ion Implantation  

SciTech Connect

Ferromagnetic Cr-doped rutile TiO? single crystals were synthesized by high-temperature ion implantation. The associated structural, compositional and magnetic properties were studied by x-ray photoelectron spectroscopy, Rutherford backscattering spectrometry, proton induced x-ray emission, x-ray diffraction, Cr K- and L-shell near-edge x-ray absorption spectroscopy, and vibrating sample magnetometry. Cr was distributed uniformly to the depth of about 300 nm with an average concentration of ~1 at. %. The samples are semiconducting and ferromagnetic as implanted, with a saturation magnetization of 0.29???B/Cr atom at room temperature. Cr is in a formal oxidation state of +3 throughout the implanted region, and no CrO? is detected.

Detection of charge transfer processes in Cr-doped SrTiO{sub 3} single crystals  

SciTech Connect

An insulator-to-metal transition is observed in Cr-doped SrTiO{sub 3} single crystals upon extended exposure to a high electric field, namely, electroconditioning (EC). Electron paramagnetic resonance (EPR) and transport measurements under laser irradiation show anticorrelation between the Cr{sup 3+} EPR signal and the electrical current. This proves that the Cr{sup 3+} ions are responsible for the photocurrent that initiates the EC process. We observe the presence of Cr{sup 3+}/Cr{sup 4+} mixed valencies in the bulk in the conducting state. The EPR characterization of the spectra in the conducting state excludes the possibility of a Cr{sup 3+}-oxygen vacancy complex in the bulk as a result of the EC.

Recovery of Cr(III) from tannery spent chrome liquor for reuse  

Science Conference Proceedings (OSTI)

This paper embodies details on the extraction behavior of Cr(III) along with Al(III), Fe(III), Mg(II), Mn(II), Co(II), Ni(II), and Cu(II) from hydrochloric acid media employing the Cyanex 301-toluene system. All of these metals, except Cr(III), Mg(II), and Mn(II), are extracted into the organic phase. This property of the extractant has been used to separate Cr(III) from the binary mixtures. The partition data have been extended onto spent chrome liquor, and this waste has been treated in such a manner so that it becomes suitable for use in trivalent plating baths. The hydrolytic stability and recycling capacity has been reported. Because the concentration of Cr(III) in the waste is much lower than that required for chromium depositions in Cr(III) plating baths, a concentration step using MgO as a precipitating agent has been appended. To summarize, this paper envisages a new approach to tannery waste management that focuses on treating spent chrome liquors using a solvent extraction technique in such a manner that the waste becomes suitable for use in trivalent plating baths. This would not only help abate pollution but also recover the metal in a pure form.

Phase decomposition in an Fe-40 at.% Cr alloy after isothermal aging and its effect on hardening  

SciTech Connect

The phase decomposition process of an Fe-40 at.% Cr alloy was studied after isothermal aging at 475 and 500 deg. C using a high-resolution transmission electron microscope, as well as hardness measurements. High-resolution transmission electron microscope observations showed that the hardening behavior is associated with the formation of the nanometric coherent decomposed Cr-rich and Fe-rich phases with irregular shape and interconnected as expected for a spinodally-decomposed alloy. As the aging progressed, coherent rounded Cr-rich phase precipitates were observed in the Fe-rich phase matrix. The coarsening process of the Cr-rich phase was observed for aging times up to 750 h. Nevertheless, no decrease in hardness with time was observed because of the nanometric size of the Cr-rich phase, less than 10 nm. Aging hardening was higher at 500 deg. C because of the higher decomposition kinetics. - Research Highlights: {yields} Spinodally-decomposed phases showed an interconnected and irregular shape in aged Fe-Cr alloy. {yields} Further aging promoted the formation of nanometric coherent rounded Cr-rich precipitates. {yields} Nanometric Cr-rich phases are responsible for the age hardening. {yields} Coarsening process of these nanometric Cr-rich precipitates caused no decrease in hardness.

Middle and upper Cambrian platform evolution and paleogeography, northwestern Montana, northern Idaho, and northeastern Washington  

Science Conference Proceedings (OSTI)

In western Montana, three Middle and Late Cambrian correlative Grand Cycles commence with inner detrital basal half cycles overlain by middle carbonate half cycles. Each half cycle represents up to one formation with the Park to Pilgrim, shale to carbonate transition, an example of one complete cycle. As with other regions of the Cambrian Cordilleran shelf, cycle components are closely related to paleogeographic position, producing differences that make correlation across depositional belts difficult. However, combined lithologic paleontologic, and cyclic correlations from southwestern Montana to isolated outcrops in northwestern Montana, northern Idaho, and northeastern Washington outline platform evolution and paleogeography. Early Middle Cambrian ramp deposition occurred with non-tectonic highs (Montania) in northwestern Montana and possible distally steepened ramps in northern Idaho. After eastward transgression, upward-shallowing Middle Cambrian carbonates formed algal-peritidal complexes that extended from central Montana to northeastern Washington. These complexes were influenced by clastic influx from central Idaho (Lemhi arch .), but they completely covered Montania and separated an eastern intrashale basin from the outer ramp. During the Late Cambrian, below wave base distal ramp carbonate deposition returned to northern Idaho and northeastern Washington. However, the distal ramp was separated from the intrashelf basin until Early Ordovician by the still existent but less extensive peritidal complexes. The ramp that developed over portions of the three states differed considerably from the cratonic margin in southern British Columbia, described by Aitken in 1966 and 1978, as a stationary accretionary rim on its seaward side persisting from Middle Cambrian to Middle Ordovician time.

CR-B-02-01 CR-B-02-01 Audit Report: CR-B-02-01 October 15, 2001 Fixed-Price Contracting for Department of Energy Cleanup Activities As part of its Contract Reform effort, the Department of Energy (Department) acted to increase its use of fixed-price contracts. This shift was designed to increase the cost-effectiveness of operations. Since October 1994, the Office of Environmental Management (EM) has awarded a number of fixed-price contracts for environmental cleanup activities. In so doing, EM expected significant cost savings when compared to approaches previously employed by management and operating contractors. Accurately estimating those savings is crucial to contracting strategy and project funding decisions, as well as the Department's overall environmental cleanup strategy.

Diode-pumped Cr:LiSAF all-solid-state femtosecond oscillator and regenerative amplifier  

Science Conference Proceedings (OSTI)

An all-solid-state tunable diode-pumped Cr{sup 3+}:LiSrAlF{sub 6} (Cr:LiSAF) regenerative amplifier, seeded by a tunable diode-pumped Cr:LiSAF femtosecond oscillator, has been demonstrated for the first time to our knowledge. The oscillator was tunable over 75 nm and generated pulses as short as 24 fs. As much as 70 mW average output power was obtained with pulses of 40-fs duration. The amplifier produced recompressed pulses of less than 200-fs duration with energies exceeding 1{mu}J at a repetition rate as high as 25 kHz. {copyright} {ital 1995} {ital Optical} {ital Society} {ital of} {ital America}.

Itinerant antiferromagnetism in BaCr2As2: Experimental characterization and electronic structure calculations  

SciTech Connect

We report single crystal synthesis, specific heat and resistivity measurements and electronic structure calculations for BaCr2As2. This material is a metal with itinerant antiferromagnetism, similar to the parent phases of Fe-based high temperature superconductors, but differs in magnetic order. Comparison of bare band structure density of states and the low temperature specific heat implies a mass renormalization of 2. BaCr2As2 shows stronger transition metal - pnictogen covalency than the Fe compounds, and in this respect is more similar to BaMn2As2. This provides an explanation for the observation that Ni and Co doping is effective in the Fe-based superconductors, but Cr or Mn doping is not.

Report: CR-B-99-02 Report: CR-B-99-02 Audit Report: CR-B-99-02 September 30, 1999 Management of Unneeded Materials and Chemicals For more than 50 years, the U.S. Department of Energy (Department) and its contractors operated large production facilities and laboratories that acquired and produced directly or as by-products enormous amounts of non-nuclear materials such as sodium, lead, chemicals, and scrap metal. However, a mission change resulting from the end of the Cold War called into question the need for continued stockpiling of these materials. In the past, the Department has conducted reviews that have identified inefficiencies and recommended improvements to the materials management function. The objective of this audit was to determine if the Department efficiently disposed of its unneeded materials.

Magnetic and electrical properties of layered magnets Tl(Cr,Mn,Co)Se{sub 2}  

Science Conference Proceedings (OSTI)

Tl(Cr,Mn,Co)Se{sub 2} crystals were synthesized at T {approx} 1050 K. X-ray diffraction analysis showed that TlCrSe{sub 2}, TlMnSe{sub 2}, and TlCoSe{sub 2} compounds crystallize in the hexagonal crystal system with the lattice parameters: a = 3.6999 A, c = 22.6901 A, c/a {approx} 6.133, z = 3, {rho}{sub x} = 6.209 g/cm{sup 3}; a = 6.53 A, c = 23.96 A, c/a {approx} 3.669, z = 8, {rho}{sub x} = 6.71 g/cm{sup 3}; and a = 3.747 A, c = 22.772 A, c/a {approx} 6.077, z = 3, {rho}{sub x} = 7.577 g/cm{sup 3}, respectively. Magnetic and electrical studies in the temperature range from 80-400 K showed that TlCrSe{sub 2} is a semiconductor ferromagnet, TlMnSe{sub 2} is a semiconductor antiferromagnet, and TlCoSe{sub 2} is a ferrimagnet with a conductivity characteristic of metals. A rather large deviation in the experimental effective magnetic moment for TlCrSe{sub 2} (3.05 {mu}B) from the theoretical value (3.85 {mu}B) is attributed to two-dimensional magnetic ordering in the paramagnetic region of the noticeably layered ferromagnet TlCrSe{sub 2}. In TlCrSe{sub 2}, a correlation between magnetic and electrical properties was detected.

Processing of LaCrO{sub 3} for solid oxide fuel cell applications  

DOE Green Energy (OSTI)

The University of Missouri-Rolla is performing a 5 year research program with two primary objectives: (1) developing LaCrO{sub 3}-based interconnect powders which densify when in contact with anode and cathode materials for solid oxide fuel cells (SOFC), and (2) developing high performance cathodes, anodes and interfaces for use in planar SOFC`s. With regard to the processing and sintering of LaCrO{sub 3}, the specific objectives of this research program are to: (1) develop a non-liquid phase sintered LaCrO{sub 3}-based material sinterable in air; (2) improve and control the properties requisite of LaCrO{sub 3} utilizing a B-site acceptor dopant; (3) optimize and control the processing conditions associated with LaCrO{sub 3}; and (4) incorporate materials developed in this program into planar cells and measure their performance. With regard to developing high performance materials for use in planar SOFC`s, the specific objectives of this research program over the last year have been to: (1) fabricate single cells with controlled microstructures for operation at 1,000 C; (2) gain a better understanding of the mechanisms involved in improving cell performance via electrochemical and impedance techniques; and (3) developing processing {leftrightarrow} microstructure {leftrightarrow} property relations of electrodes and their corresponding interfacial reactions. This report is divided into two primary sections: (1) LaCrO{sub 3} sintering studies and (2) SOFC performance studies. Results from these studies are presented in the following sections.

Microstructure and High Temperature Oxidation Behavior of Cr-W Alloys  

Science Conference Proceedings (OSTI)

Cr alloys containing 0-30%W by weight were investigated for use in elevated temperature applications. The alloys were melted in a water-cooled, copper-hearth arc furnace. Microstructure of the alloys was characterized using x-ray diffraction, scanning electron microscopy, and light microscopy. A pseudocyclic oxidation test was employed to study scale formation at 1000C in dry air. The scale was predominantly chromia and spalled upon cooling. Alloying with aluminum up to 8 weight percent reduced the spalling drastically. Furthermore, aluminizing the surface of the Cr-W alloys completely stopped the spalling.

Oxygen-17 NMR Shifts Caused by Cr{Sup ++} in Aqueous Solutions  

DOE R&D Accomplishments (OSTI)

Cr{sup ++} in solution produces a paramagnetic shift in the NMR absorption of O{sup 17} in ClO{sub 4}{sup -}, as well as the expected paramagnetic shift for O{sup 17} in H{sub 2}O. As the concentration of ClO{sub 4}{sup -} increases, the shift in the H{sub 2}O{sup 17} absorption is diminished, and eventually changes sign. The effects are ascribed to preferential replacement by ClO{sub 4}{sup -} of water molecules from the axial positions in the first coordination sphere about Cr{sup ++}.

Substitution of modified 9 Cr-1 Mo steel for austentic stainless steels  

SciTech Connect

This report describes the current program to develop a high-strength ferritic-martensitic steel. The alloy is essentially Fe-9% Cr-1% Mo with small additions of V and Nb and is known as modifed 9 Cr-1 Mo steel. Its elevated-temperature properties and design allowable stresses match those of type 304 stainless steel for temperatures up to 600/sup 0/C and exceed those of other ferritic steels by factors of 2 to 3. The improved strength of this alloy permits its use in place of stainless steels for many applications.

Science Conference Proceedings (OSTI)

CR-39 detectors were exposed to DT neutrons generated by a Thermo Fisher model A290 neutron generator. Afterwards, the etched tracks were examined both optically and by SEM. The purpose of the analysis was to compare the two techniques and to determine whether additional information on track geometry could be obtained by SEM analysis. The use of these techniques to examine triple tracks, diagnostic of ?9.6 MeV neutrons, observed in CR-39 used in Pd/D codeposition experiments will also be discussed.

Dual and Triple Ion-Beam Irradiations of Fe, Fe(Cr) and Fe(Cr)-ODS Final Report: IAEA SMoRE CRP  

DOE Green Energy (OSTI)

Structures of nanoparticles in Fe-16Cr-4.5Al-0.3Ti-2W-0.37Y2O3 (K3) and Fe-20Cr-4.5Al-0.34Ti-0.5Y2O3 (MA956) oxide dispersion strengthened (ODS) ferritic steels produced by mechanical alloying (MA) and followed by hot extrusion have been studied using high-resolution transmission electron microscopy (HRTEM) techniques to gain insight about the formation mechanism of nanoparticles in MA/ODS steels. The observations of Y-Al-O complex-oxide nanoparticles in both ODS steels imply that decomposition of Y2O3 in association with internal oxidation of Al occurred during mechanical alloying. While the majority of oxide nanoparticles formed in both steels is Y4Al2O9, a few oxide particles of YAlO3 are also occasionally observed. These results reveal that Ti (0.3 wt %) plays an insignificant role in forming oxide nanoparticles in the presence of Al (4.5 wt %). HRTEM observations of crystalline nanoparticles larger than {approx}2 nm and amorphous or disordered cluster domains smaller than {approx}2 nm provide an insight into the formation mechanism of oxide nanoparticle in MA/ODS steels, which we believe from our observations involves a solid-state amorphous precursor followed by recrystallization. Dual ion-beam irradiations using He{sup +} + Fe{sup +8} ions were employed to gain more detailed insight about the role of nanoparticles in suppressing radiation-induced swelling. This is elaborated through TEM examinations of cavity distributions in ion-irradiated Fe-14Cr and K3-ODS ferritic steels. HRTEM observations of helium-filled cavities (helium bubbles) preferably trapped at nanoscale oxide particles and clusters in ion-irradiated K3-ODS are presented. Finally, we describe the results from triple ion-beam irradiations using H{sup +} + He{sup +} + Fe{sup +8} ions to emulate fusion first wall radiation effects. Preliminary work is reported that confirms the existence of significant hydrogen synergistic effects described earlier by Tanaka et al., for Fe(Cr) and by Wakai et al., for F82H reduced activation ferritic martensitic (RAF/M) steel. These previous results combined with our data suggest a complex new 'catalytic' mechanism whereby H interacts with the steady state population of defects and the embryonic cavities so as to accelerated cavity (void) growth in both Fe(Cr) and under special conditions in ODS steels.

Investigation of Modified Ni-Cr-Mn Base Alloys for SOFC Interconnect Applications  

Science Conference Proceedings (OSTI)

Two Ni-Cr-W-Mn base alloys based on Haynes 230 were developed and evaluated against criteria relevant to SOFC interconnect applications, which included oxidation behavior under SOFC operating conditions, scale electrical conductivity, and thermal expansion. It was found that, similar to the ferritic stainless steel Crofer22 APU, additions of Mn led to the formation of a unique scale that was comprised of a M3O4 (M=Mn, Cr, Ni, ) spinel-rich top layer and Cr2O3-rich sub-layer. The modified alloys demonstrated reasonable oxidation resistance under SOFC operating conditions, though the Mn additions increased the scale growth rate and thus sacrificed to some extent the oxidation resistance of the base alloy (Haynes 230). The formation of a spinel-rich top layer improved the scale conductivity, especially during the early stages of oxidation, but the higher scale growth rate resulted in a higher rate of increase in the area-specific electrical resistance. Due to their FCC crystal structure, the Ni-Cr-W-Mn base alloys demonstrated a CTE that was higher than that of anode-supported cells and candidate ferritic stainless steels such as Crofer22 APU.

Investigations of HRC-Stimulated Bioreduction of Cr(VI) at Hanford 100H  

DOE Green Energy (OSTI)

Hypothesis: Lactate (Hydrogen Release Compound-HRC{trademark}) injection into chromium contaminated groundwater through an injection well will cause indirect or direct bioreduction of chromate [Cr(VI)] and precipitation of insoluble species of [Cr(III)] on soil particles, probably catalyzed at oxide surfaces, at the field scale. Objective: Assess the potential for immobilizing and detoxifying chromium-contaminated groundwater using lactate-stimulated bioreduction of Cr(VI) to Cr(III) at the Hanford Site's 100-H Area field site. Types of Research: A three-well system (injection well and upgradient and downgradient monitoring wells) was used for conducting the in situ biostimulation and monitoring. To assess the pre- and post-injection test groundwater conditions, we used an integrated monitoring approach, involving hydraulic, geochemical, microbial, and geophysical techniques and analytical methods, as well as conducted five Br-tracer injection tests and four pumping tests (concurrently with the Br-tracer tests). Groundwater biostimulation was conducted by injection of 40 lbs of {sup 13}C-labeled HRC into the injection well (over the depth interval from 44-50 ft) on 8/3/2004, followed by low-flow pumping (1.2 to 2.5 l/min) through the downgradient well (to ensure capture of groundwater flow lines passing through the injection well) for 27 days. Main Results: Although the total microbial population in sediments is relatively low (<10{sup 5} cells g-1) under background conditions, which is likely insufficient for direct enzymatic Cr(VI) reduction, several types of bacteria, e.g., Bacillus/Arthrobacter and Geobacter, are present in the Hanford sediments, which are known to reduce or sorb hexavalent chromium. The HRC injection stimulated microbial cell counts to reach the maximum of 2 x 10{sup 7} cells g{sup -1} 13-17 days after the injection, and generated highly reducing conditions. Geochemical and isotopic observations confirmed microbial metabolism of HRC. The Cr(VI) concentration in the monitoring and pumping wells decreased below drinking water minimum contaminant limits and remained below background concentrations even after 1.5 years, when redox conditions and microbial densities had returned to background levels. Fe(II) levels have remained high and may account for the continued reduction of Cr(VI).

Rare-earth chromium gallides RE{sub 4}CrGa{sub 12} (RE=Tb-Tm)  

Science Conference Proceedings (OSTI)

The ternary rare-earth-metal chromium gallides RE{sub 4}CrGa{sub 12} (RE=Tb-Tm) have been prepared by reactions of the elements at 1000 Degree-Sign C in the presence of excess gallium used as a self-flux. Their structures are derived by inserting Cr atoms into a quarter of the empty Ga{sub 6} octahedral clusters found in the parent binary gallides REGa{sub 3} (AuCu{sub 3}-type), although single-crystal X-ray diffraction studies suggest that complex superstructures may be adopted. An ideal ordered Y{sub 4}PdGa{sub 12}-type structure was successfully refined for a crystal of Dy{sub 4}CrGa{sub 12} (Pearson symbol cI34, space group Im3{sup Macron }m, Z=2, a=8.572(1) A). Magnetic measurements on single-crystal samples reveal ferromagnetic or possibly ferrimagnetic ordering for the Tb, Dy, and Er members (T{sub C}=22, 15, and 2.8 K, respectively) and antiferromagnetic ordering for the Ho member (T{sub N}=7.5 K). Band structure calculations on a hypothetical 'Y{sub 4}CrGa{sub 12}' model suggest that the Cr atoms carry no local magnetic moment. - Graphical abstract: RE{sub 4}CrGa{sub 12} is derived by inserting Cr atoms into empty Ga{sub 6} octahedral clusters present in the parent binary gallides REGa{sub 3}. Highlights: Black-Right-Pointing-Pointer RE{sub 4}MGa{sub 12} (previously known for M=Fe, Ni, Pd, Pt, Ag) has been extended to M=Cr. Black-Right-Pointing-Pointer RE{sub 4}CrGa{sub 12} compounds show predominantly ferromagnetic ordering. Black-Right-Pointing-Pointer Band structure calculations suggest that Cr atoms carry no local magnetic moment.

Fate of Cu, Cr, and As during combustion of impregnated wood with and without peat additive  

SciTech Connect

The EU Directive on incineration of waste regulates the harmful emissions of particles and twelve toxic elements, including copper, chromium, and arsenic. Using a 15 kW pellets-fueled grate burner, experiments were performed to determine the fate of copper, chromium, and arsenic during combustion of chromate copper arsenate (CCA) preservative wood. The fate and speciation of copper, chromium, and arsenic were determined from analysis of the flue gas particles and the bottom ash using SEM-EDS, XRD, XPS, and ICP-AES. Chemical equilibrium model calculations were performed to interpret the experimental findings. The results revealed that about 5% copper, 15% chromium, and 60% arsenic were volatilized during combustion of pure CCA-wood, which is lower than predicted volatilization from the individual arsenic, chromium, and copper oxides. This is explained by the formation of more stable refractory complex oxide phases for which the stability trends and patterns are presented. When co-combusted with peat, an additional stabilization of these phases was obtained and thus a small but noteworthy decrease in volatilization of all three elements was observed. The major identified phases for all fuels were CuCrO{sub 2}(s), (Fe,Mg,Cu)(Cr,Fe,Al)O{sub 4}(s), Cr{sub 2}O{sub 3}(s), and Ca{sub 3}(AsO{sub 4}){sub 2}(s). Arsenic was also identified in the fine particles as KH{sub 2}AsO{sub 4}(s) and As{sub 2}O{sub 3}). A strong indication of hexavalent chromium in the form of K{sub 2}CrO{sub 4} or as a solid solution between K{sub 3}Na(CrO{sub 4}){sub 2} and K{sub 3}Na(SO{sub 4}){sub 2} was found in the fine particles. Good qualitative agreement was observed between experimental data and chemical equilibrium model calculations. 38 refs., 6 figs., 2 tabs.

Minerals yearbook: Mineral industries of the Middle East. Volume 3. 1989 international review  

SciTech Connect

The production and processing of crude petroleum and natural gas are the dominant economic sectors of the Middle East. The 15 countries that constitute the region accounted for 26% of world crude petroleum output, 17% of world natural gas plant liquid production, and almost 5% of world dry natural gas production. About 66% of total world crude petroleum reserves and 31% of total world natural gas reserves are in the Middle East. U.S. imports of mineral-based materials from the region were primarily energy products. U.S. net oil imports from the Middle East, which include crude petroleum, natural gas liquids, and petroleum refinery products, were about 26% of total U.S. net oil imports or about 680 million barrels in 1989.

Gas projects surge in the Middle East as governments seek new revenue sources  

SciTech Connect

The rapid development of natural gas and condensate reserves in the Middle East results from a simple motivation: the desire of governments to earn revenues. For the past decade, Middle East governments have run budget deficits, which they funded by drawing down foreign assets and issuing debt. Now in the process of structural economic reform, they have begun to use an under-utilized resource--natural gas, of which Middle East governments own about one third of the world`s reserves. Governments receive revenues from several sources in natural gas developments, which makes the projects very attractive. Revenue comes from the sale of the natural gas in the domestic market and, if exported, the international market; the sale of associated condensates; the additional exports of crude oil or refined products if natural gas is substituted for refined products in domestic markets; the increased sale of crude oil if natural gas is injected into reservoirs to maintain pressure; and the sale of petrochemicals where natural gas is used as feedstock. Large projects under way in the Middle East highlight the consequences of multiple revenue sources and interlinked costs of natural gas and condensate development. Other countries in the region are undertaking similar projects, so examples cited represent only a portion of what is occurring. The paper describes Abu Dhabi, Qatar, Saudi Arabia, and Iran.

Absence of long-range chemical ordering in equimolar FeCoCrNi  

Science Conference Proceedings (OSTI)

Equimolar FeCoCrNi alloys have been the topic of recent research as 'high-entropy alloys,' where the name is derived from the high configurational entropy of mixing for a random solid solution. Despite their name, no systematic study of ordering in this alloy system has been performed to date. Here, we present results from anomalous x-ray scattering and neutron scattering on quenched and annealed samples. An alloy of FeNi{sub 3} was prepared in the same manner to act as a control. Evidence of long-range chemical ordering is clearly observed in the annealed FeNi{sub 3} sample from both experimental techniques. The FeCoCrNi sample given the same heat treatment lacks long-range chemical order.

High-reflectivity Cr/Sc multilayer condenser for compact soft x-ray microscopy  

Science Conference Proceedings (OSTI)

The condenser is a critical component in compact water-window x-ray microscopes as it influences the exposure time via its efficiency and the resolution via its numerical aperture. Normal-incidence multilayer mirrors can reach large geometrical collection efficiencies and match the numerical aperture of the zone plate but require advanced processing for high total reflectivity. In the present article we demonstrate large-diameter normal-incidence spherical Cr/Sc multilayer condensers with high and uniform reflectivity. Dc-magnetron sputtering was used to deposit 300 bilayers of Cr/Sc with a predetermined d-spacing matching the {lambda}=3.374 nm operating wavelength on spherical substrates. The mirrors show a uniform reflectivity of {approx}3% over the full 58 mm diameter condenser area. With these mirrors an improvement in exposure time by a factor of 10 was achieved, thereby improving the performance of the compact x-ray microscope significantly.

Corrosion Behavior of NiCrFe Alloy 600 in High Temperature, Hydrogenated Water  

SciTech Connect

The corrosion behavior of Alloy 600 (UNS N06600) is investigated in hydrogenated water at 260 C. The corrosion kinetics are observed to be parabolic, the parabolic rate constant being determined by chemical descaling to be 0.055 mg dm{sup -2} hr{sup -1/2}. A combination of scanning and transmission electron microscopy, supplemented by energy dispersive X-ray spectroscopy and grazing incidence X-ray diffraction, are used to identify the oxide phases present (i.e., spinel) and to characterize their morphology and thickness. Two oxide layers are identified: an outer, ferrite-rich layer and an inner, chromite-rich layer. X-ray photoelectron spectroscopy with argon ion milling and target factor analysis is applied to determine spinel stoichiometry; the inner layer is (Ni{sub 0.7}Fe{sub 0.3})(Fe{sub 0.3}Cr{sub 0.7}){sub 2}O{sub 4}, while the outer layer is (Ni{sub 0.9}Fe{sub 0.1})(Fe{sub 0.85}Cr{sub 0.15}){sub 2}O{sub 4}. The distribution of trivalent iron and chromium cations in the inner and outer oxide layers is essentially the same as that found previously in stainless steel corrosion oxides, thus confirming their invariant nature as solvi in the immiscible spinel binary Fe{sub 3}O{sub 4}-FeCr{sub 2}O{sub 4} (or NiFe{sub 2}O{sub 4}-NiCr{sub 2}O{sub 4}). Although oxidation occurred non-selectively, excess quantities of nickel(II) oxide were not found. Instead, the excess nickel was accounted for as recrystallized nickel metal in the inner layer, as additional nickel ferrite in the outer layer, formed by pickup of iron ions from the aqueous phase, and by selective release to the aqueous phase.

Geothermal-heating facilities for Carson Elementary School and Wind River Middle School  

DOE Green Energy (OSTI)

Carson Elementary School and Wind River Middle School are located in Carson, Washington, adjacent to the Wind River. Both schools are operated by the Stevenson-Carson School District. Carson Elementary, comprised of 49,000 square feet, was constructed in several phases beginning in 1951. The construction is variable, but is characterized by large expanses of single glass and uninsulated masonry areas. An oil fired steam boiler supplies a variety of terminal equipment. Wind River Middle School was built in 1972 and, as a result, exhibits much greater insulation levels. The 38,000 square foot structure is heated entirely by an electric resistance terminal reheat system. Carson Hot Springs Resort, located approximately one half mile from the schools, exhibits temperatures of 124/sup 0/F. In addition, geological work is in progress to better define the local geothermal resource. The feasibility of geothermal use at the school for space heating purposes is examined.

Future expansion of crude oil production capacity in the Middle East is anything but certain-at least with crude prices at recent levels. There is little doubt that the world will need more production capacity than now exists unless petroleum consumption sags. And there is even less doubt about where prospects are best for production capacity growth. The paper discusses the normal surplus, growing demand, financial conditions, and political stability.

Assessment of the mechanical performance of the Westinghouse BWR control rod CR 99 at high depletion levels  

SciTech Connect

A long-term program assessing the mechanical performance of the Westinghouse BWR control rod CR 99 at high depletion levels has been performed. The scope of the program has mainly been based on the operation of four CR 99 Generation 2 control rods in demanding positions during 6 and 7 cycles in the Leibstadt Nuclear Power Plant (KKL) and on the detailed visual inspections and blade wing thickness measurements that were performed after the rods were discharged. By correlating statistically the blade wing thickness measurements to the appearance of irradiation-assisted stress corrosion cracking (IASCC), the probability of IASCC appearance as function of the blade wing swelling was estimated. In order to correlate the IASCC probability of a CR 99 to its depletion, the {sup 10}B depletion of the studied rods was calculated in detail on a local level with the stochastic Monte Carlo code MCNP in combination with the Westinghouse nodal code system PHOENIX4/POLCA7. Using this information coupled to the blade wing measurement data, a finite element model describing the blade wing swelling of an arbitrary CR 99 design as function of {sup 10}B depletion could then be generated. In the final step, these relationships were used to quantify the probability of IASCC appearance as function of the {sup 10}B depletion of the CR 99 Generations 2 and 3. Applying this detailed mapping of the CR 99 behavior at high depletion levels and using an on-line core monitoring system with explicit {sup 10}B depletion tracking capabilities will enable a reliable prediction of the probability for IASCC appearance, thus enhancing the optimized design and the sound operation of the CR 99 control rod. Another important outcome of the program was that it was clearly shown that no significant amount of boron leakage did occur through any of the detected IASCC cracks, despite the very high depletion levels achieved.

The Impact of Social Space Design on Students Behavioral Problems in Middle Schools  

E-Print Network (OSTI)

This study examined the impact of social space design on student behavioral problems in middle schools. A mixed-method approach was used in the form of focus groups and surveys with teachers and students from four central Texas middle schools (7th and 8th grade). Social space was defined as any space that students use while not in the classroom (e.g., hallways, cafeteria and outdoor spaces). Negative behavioral patterns were defined by the schools themselves but typically were any act that is physically or emotionally harmful to another student, oneself, or school property (e.g., stealing, fighting and name-calling). For each space, design elements that were analyzed included seating, privacy, equipment, structure, and open space. Within one school, four key spaces were identified and students were surveyed regarding their opinions of the design and behavioral patterns within each space. Comparisons across spaces within and among the four schools showed areas that are overcrowded or lack supervision exhibit higher accounts of negative behavior. Structured social spaces and outdoor spaces have less instances of problematic behavior but only when overcrowding is not a problem. This study also uncovered design factors that were important to the students but were not originally considered such as their desire for safety. This result highlights the importance of student voice in design. Overcrowding, supervision and the balance of privacy and safety emerged as the main issues regarding social space design and behavioral patterns in middle schools.

Rock bits equipped with extended nozzles lower drilling cost in the Middle East region  

Science Conference Proceedings (OSTI)

An analysis of three-cone rock bit runs using extended jet nozzles (EN) in the Middle East Region is presented. These runs were made from 1982 to 1984 in several Middle East countries. They represent wells drilled onshore and offshore, vertical and deviated, using oil and water based mud systems. The improvements in performance gained by enhanced hole cleaning with extended nozzles are well documented. This feature has been widely used in the South East Asia - Far East region and in certain areas of the continental U.S.A. and Alaska since the mid - 1970's. The result of the EN runs in the Middle East correlate well with results in the proven areas elsewhere in the world. Penetration rate increases over regular jet bits of 7-80% have been recorded. The high daily rig costs characteristic of Mideast drilling operations make it fairly easy to show a cost per foot decrease with only slight increases in performance. The increased bit cost due to the EN feature is found to be virtually negligible.

Thirty-one O-anomalous grains were detected: 24 were identified as silicates ({approx}78 ppm); the remaining 7 are Al-rich oxides ({approx}38 ppm). NWA 852 is the first C2 chondrite containing O-anomalous presolar dust in concentrations comparable to other more primitive meteorites. Eight presolar SiC grains have been found, representing the highest abundance ({approx}160 ppm) observed so far in primitive meteorites. {sup 15}N-enriched matter is also present, although very heterogeneously distributed. Twenty-six of the O-anomalous grains are enriched in {sup 17}O, originating from the outflows of low-mass asymptotic giant branch (AGB) stars. We calculate a silicate/oxide abundance ratio of {approx}2, which indicates a higher degree of aqueous alteration than observed for other presolar-grain-rich meteorites. NWA 852 thus stands between the presolar-grain-rich CR3 chondrites (MET 00426, QUE 99177) and CR2 chondrites with low presolar grain abundances (Renazzo, NWA 530). We calculate an initial presolar silicate abundance of {approx}800 ppm for NWA 852, if silicate destruction by aqueous alteration is taken into account. Transmission electron microscope (TEM) investigation of one presolar Al-rich grain of an AGB star origin revealed that the grain mainly consists of a single crystal of hibonite with slightly varying orientations. A distinct subgrain (d < 100 nm) with a Ca/Ti ratio of {approx}1 is located in the central region, most likely indicating a perovskite-like phase. Our data suggest this phase to be a primary condensate and not an alteration product.

COMPREHENSIVE OBSERVATIONS OF THE ULTRAVIOLET SPECTRUM AND IMPROVED ENERGY LEVELS FOR SINGLY IONIZED CHROMIUM (Cr II)  

SciTech Connect

We report new observations of the spectrum of singly ionized chromium (Cr II) in the region 1142-3954 A. The spectra were recorded with the National Institute of Standards and Technology 10.7 m normal-incidence vacuum spectrograph and FT700 vacuum ultraviolet Fourier transform spectrometer. More than 3600 lines are classified as transitions among 283 even and 368 odd levels. The new spectral data are used to re-optimize the energy levels, reducing their uncertainties by a typical factor of 20.

Prospective and Practicing Middle School Teachers' Knowledge of Curriculum for Teaching Simple Algebraic Equations  

E-Print Network (OSTI)

Knowledge of curriculum is a significant component of mathematical knowledge for teaching. However, clearly understanding knowledge of curriculum requires further refinement and substantial research. This study consists of three papers that aim to explore prospective and practicing middle school teachers Knowledge of Curriculum for Teaching Simple Algebraic Equations (KCTE). The first paper reviews trends in and the evolution of standards and policies and synthesizes significant findings of research on mathematics curriculum and Knowledge of Curriculum for Mathematics Teaching (KCMT). Through this synthesis, the paper examines policy changes and research relevant to mathematics curriculum and KCMT and anticipates future research approaches and topics that show promise. Building on the context provided by the first paper, the following two papers investigate KCTE from the perspectives of prospective and practicing middle school mathematics teachers. For the second paper, data was collected from a convenience sample of 58 prospective middle school mathematics teachers and a subsample of six participants. The findings of this study identify patterns of key mathematical topics in the teaching sequence of simple algebraic equations, compare the participants sequences with experts, reveal participants orientations toward KCTE, draw connections between participants KCTE and their knowledge of content and teaching, and establish relationships between participants KCTE and their knowledge of content and students. Four middle school mathematics teachers participated in the third study. The results indicate that state-level intended curriculum is the most prevailing component of participants KCTE. Furthermore, from a vertical view of curriculum, participants awareness of their students lack of basic mathematical knowledge impacted their KCTE. The paper also identifies the role of the state-level intended curriculum in participants KCTE, alternative approaches to curriculum implementation that participants used to respond to the multiple intelligences of their students, and the participants lack of lateral curriculum knowledge in KCTE. Together, these three papers offer a closer look at KCMT with a focus on simple algebraic equations. This research broadens our understanding of prospective and practicing middle school teachers KCMT and discusses implications for professional development.

Chromium Grain-boundary Segregation and Effect of Ion Beam Cleaning on Fe-Ni-Cr Alloys  

SciTech Connect

The grain boundaries play important role to control the mechanical strength of ternary alloys. From spacecrafts to naval vessels to nuclear reactors, stress corrosion cracking, brittleness, oxidation mostly originates at the grain boundaries and cause long term structural stability problems in most of the metallic structures [1]. Fe-Ni-Cr based ternary metal alloys have been widely studied for more than fifty years [2, 3]. Despite of vast amount of research, chromium diffusion in stainless steel or other Ni-Fe-Cr based ternary alloys is still an open scientific problem with challenges in structural stability and corrosion resistance [4]. Particularly, austenite Fe-Ni-Cr is looked upon favorably in space and jet engine industry for their improved resistance to stress corrosion cracking [5]. In solid oxide fuel cells (SOFC), Ni-alloys are frequently used as interconnects and seals [6]. In this communication, simultaneous energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD) mapping is utilized to study chemical and structural aspects of chromium segregation in Fe-Ni-Cr alloy. A focused Ga-ion beam is also utilized to study the effect of ion beam cleaning on EBSD image quality (IQ) and inverse pole figure (IPF) maps of Fe-Ni-Cr alloy.

Aqueous chemical growth of alpha-Fe2O3-alpha-Cr203 nanocompositethin films  

DOE Green Energy (OSTI)

We are reporting here on the inexpensive fabrication and optical properties of an iron(III) oxide chromium(III) oxide nanocomposite thin film of corundum crystal structure. Its novel and unique-designed architecture consists of uniformed, well-defined and oriented nanorods of Hematite (alpha-Fe2O3) of 50 nm in diameter and 500nm in length and homogeneously distributed nonaggregated monodisperse spherical nanoparticles of Eskolaite (alpha-Cr2O3) of 250 nm in diameter. This alpha-Fe2O3 alpha-Cr2O3 nanocomposite thin film is obtained by growing, directly onto transparent polycrystalline conducting substrate, an oriented layer of hematite nanorods and growing subsequently, the eskolaite layer. The synthesis is carried out by a template-free, low-temperature, multilayer thin film coating process using aqueous solution of metal salts as precursors. Almost 100 percent of the light is absorbed by the composite film between 300 and 525 nm and 40 percent at 800 nm which yields great expectations as photoanode materials for photovoltaic cells and photocatalytic devices.

Microstructure control for high strength 9Cr ferritic-martensitic steels  

SciTech Connect

Ferritic-martensitic (F-M) steels with 9 wt.%Cr are important structural materials for use in advanced nuclear reactors. Alloying composition adjustment, guided by computational thermodynamics, and thermomechanical treatment (TMT) were employed to develop high strength 9Cr F-M steels. Samples of four heats with controlled compositions were subjected to normalization and tempering (N&T) and TMT, respectively. Their mechanical properties were assessed by Vickers hardness and tensile testing. Ta-alloying showed significant strengthening effect. The TMT samples showed strength superior to the N&T samples with similar ductility. All the samples showed greater strength than NF616, which was either comparable to or greater than the literature data of the PM2000 oxide-dispersion-strengthened (ODS) steel at temperatures up to 650 C without noticeable reduction in ductility. A variety of microstructural analyses together with computational thermodynamics provided rational interpretations on the strength enhancement. Creep tests are being initiated because the increased yield strength of the TMT samples is not able to deduce their long-term creep behavior.

Relationships between processing, microstructure, and properties of a Co-Cr-Mo alloy  

SciTech Connect

STELLITE alloy No. 21 was produced via rapid solidification processing (RSP) in a variety of particulate morphologies (coarse and fine powder, flakes, fibers, and ribbons). The various RSP forms showed similar, fine microstructures with only a slight difference in the scale of the microstructural features. These RSP particulates were consolidated by extrusion, dynamic compaction, and rapid omnidirectional compaction (ROC) at two processing temperatures (1077/sup 0/C and 1121/sup 0/C). Dynamic compaction proved to be unacceptable for this alloy because of non-uniform porosity and the inability to develop a metallurgical bond between particulates. A plot of elongation versus yield strength depicted two yield strength/ductility relationships for the Co-Cr-Mo type alloys. As-ROC'd samples had a low yield strength/ductility relationship. Atomized powder size also affected the strength/ductility relationships of the extruded products. Decreasing powder size increased ductility without effecting yield strength. Processing temperature did not affect the yield strength/ductility relationship. Electrochemical polarization tests were not successful in delineating fine differences between the various types of Co-Cr-Mo alloy while immersion-pitting temperature tests were capable of distinguishing between samples processed from fine and coarse powders. These materials proved susceptible to stress corrosion cracking (SCC) in boiling 30% MgCl/sub 2/.

Oxidation Resistant, Cr Retaining, Electrically Conductive Coatings on Metallic Alloys for SOFC Interconnects  

DOE Green Energy (OSTI)

This report describes significant results from an on-going, collaborative effort to enable the use of inexpensive metallic alloys as interconnects in planar solid oxide fuel cells (SOFCs) through the use of advanced coating technologies. Arcomac Surface Engineering, LLC, under the leadership of Dr. Vladimir Gorokhovsky, is investigating filtered-arc and filtered-arc plasma-assisted hybrid coating deposition technologies to promote oxidation resistance, eliminate Cr volatility, and stabilize the electrical conductivity of both standard and specialty steel alloys of interest for SOFC metallic interconnect (IC) applications. Arcomac has successfully developed technologies and processes to deposit coatings with excellent adhesion, which have demonstrated a substantial increase in high temperature oxidation resistance, stabilization of low Area Specific Resistance values and significantly decrease Cr volatility. An extensive matrix of deposition processes, coating compositions and architectures was evaluated. Technical performance of coated and uncoated sample coupons during exposures to SOFC interconnect-relevant conditions is discussed, and promising future directions are considered. Cost analyses have been prepared based on assessment of plasma processing parameters, which demonstrate the feasibility of the proposed surface engineering process for SOFC metallic IC applications.

Ab initio study on noncompensated CrO codoping of GaN for enhanced solar energy conversion  

SciTech Connect

We describe a novel photocatalyst obtained by codoping GaN with CrO, according to a new "noncompensated" codoping concept based on first-principles calculations. The approach enables controllable narrowing of the GaN band gap with significantly enhanced carrier mobility and photocatalytic activity in the visible light region and thus offers immense potential for application in solar energy conversion, water splitting, and a variety of solar-assisted photocatalysis. Our calculations indicate that the formation energy for the cation doping is greatly reduced by noncompensated codoping with an anion. Although Cr doping alone can split the band gap with the formation of an intermediate band, the mobility is low due to carrier trapping by the localized states. The first-principles calculations also demonstrate that CrO codoping of GaN shifts the Fermi level into the conduction band resulting in high carrier density and mobility.

Development of a New Class of Fe-3Cr-W(V) Ferritic Steels for Industrial Process Applications  

SciTech Connect

The project described in this report dealt with improving the materials performance and fabrication for hydrotreating reactor vessels, heat recovery systems, and other components for the petroleum and chemical industries. These reactor vessels can approach ship weights of about 300 tons with vessel wall thicknesses of 3 to 8 inches. They are typically fabricated from Fe-Cr-Mo alloy steels, containing 1.25 to 12% chromium and 1 to 2% molybdenum. The goal of this project was to develop Fe-Cr-W(V) steels that can perform similar duties, in terms of strength at high temperatures, but will weigh less and thereby save energy.

CHANGES IN SANDSTONE DISTRIBUTIONS BETWEEN THE UPPER, MIDDLE, AND LOWER FAN IN THE ARKANSAS JACKFORK GROUP  

E-Print Network (OSTI)

This study is a statistical analysis of the sandstone distribution within the Arkansas Jackfork Group which is a passive margin fan complex. Passive margin fan systems are typically associated with long fluvial transport, fed by deltas, wide shelf, efficient basin transport, that result in a bypassing system. Passive margin fans are generally fine-grained, mud rich, and well sorted. These fans can be separated into three units (upper, middle, and lower fan) based on their location within the fan and how the sediments are deposited. Five outcrops from the Arkansas Jackfork Group have been chosen for this study and each were divided into different facies dependent on sandstone percentages in certain bed sets. The amount of sandstone for each facies was calculated and a statistical approximation for each outcrop was determined. Sandstone distribution curves were made for each outcrop to show a graphic representation of how the sandstone is dispersed. After analyzing different upper, middle, and lower fan outcrops, it is clear there is an obvious change in the sandstone percentage and distribution. The upper fan deposit has an overall sandstone percentage of approximately 77.5% and is deposited in beds that are mainly amalgamated; 10-30m thick. Sandstone is deposited moderately even and is quite concentrated throughout the exposure. The middle fan outcrops contain approximately 72.6% sandstone and show similar patterns, except that the amalgamated sandstone beds are not as thick, 5-15m and contain more shale in between layers. As expected the lower fan outcrop is completely different in both sandstone percentage and distribution. The lower fan has approximately 65.4% sandstone. The distribution of sandstone is more concentrated in each of the individual units, or systems, but the overall complex has two systems separated by a massive marine shale bed, 33.5 m, that contains virtually no sand.

The influence of temperature on the color of TiO{sub 2}:Cr pigments  

Science Conference Proceedings (OSTI)

TiO{sub 2}:Cr brown pigments were prepared via a polymeric precursor derived from the Pechini method. The pigments were analyzed by infrared spectroscopy, X-ray diffraction, ultraviolet-vis spectroscopy, and colorimetry. The increase of the calcination temperature from 700 to 1000 deg. C led to a decrease in the L* values, corresponding to darkening of the pigments. The pigments obtained in this work are darker than those produced by a solid-state reaction method reported before. The change in the pigment color is due to the anatase-rutile phase transition, which leads to a shift in the charge transfer bond (Ti{sup 4+} {r_reversible} O{sup 2-}) due to a change in the crystal field around the chromophore ions. Moreover, the oxidation state of chromium was observed to change, and this also alters the color of the pigments.

Thermodynamic modeling and experimental validation of the Fe-Al-Ni-Cr-Mo alloy system  

SciTech Connect

NiAl-type precipitate-strengthened ferritic steels have been known as potential materials for the steam turbine applications. In this study, thermodynamic descriptions of the B2-NiAl type nano-scaled precipitates and body-centered-cubic (BCC) Fe matrix phase for four alloys based on the Fe-Al-Ni-Cr-Mo system were developed as a function of the alloy composition at the aging temperature. The calculated phase structure, composition, and volume fraction were validated by the experimental investigations using synchrotron X-ray diffraction and atom probe tomography. With the ability to accurately predict the key microstructural features related to the mechanical properties in a given alloy system, the established thermodynamic model in the current study may significantly accelerate the alloy design process of the NiAl-strengthened ferritic steels.

Sliding wear, toughness and microstructural relationships in high strength Fe/Cr/C experimental steels  

Science Conference Proceedings (OSTI)

Hardness has been believed to be the major parameter influencing wear resistance of materials. Recently, it was suggested that combinations of high strength and toughness may lead to optimum wear resistance. It is known that the martensite transformation can be exploited to provide a variety of strength-toughness combinations. Small additions of Mn or Ni to the Fe/4Cr/.3C martensitic alloys have been shown to increase toughness while maintaining strength via increasing the volume fraction of retained austenite. An investigation of the relationships between microstructure, toughness, and sliding wear resistance for these experimental alloys is reported. Comparative studies were performed on several industrial alloys to provide a practical basis for comparison of these medium carbon experimental steels.

L-shell photoabsorption spectroscopy for solid metals: Ti, V, Cr, Fe, Ni, Cu  

Science Conference Proceedings (OSTI)

Synchrotron radiation measurements of near-threshold and broad-range (400--1500 eV) absolute photoabsorption cross sections were made for five transition metals with {plus minus}10% overall uncertainties. Fine structure details of 2p-3d autoionizing resonances are shown with better than 1.0 eV resolution for solid metals: Ti, V, Cr, Fe, Ni, and Cu. Fine structure similar to what we measured can be produced using a multi-configuration Dirac Fock (MCDF) model if a statistical distribution is assumed for the initial atomic states. Calculations were performed in intermediate coupling with configuration interactions by Mau H. Chen. The results are compared with other experimental work and theoretical methodologies. 18 refs., 7 figs.

Interferometric measurement of melt depth in silicon using femtosecond infrared Cr:forsterite laser  

SciTech Connect

Interferometric microscopy technique combined with high power infrared Cr:forsterite laser system was applied to investigate femtosecond laser induced melting of silicon. Optically polished wafer of single crystalline silicon of 400 {mu}m thickness was irradiated with 100 fs pump pulses at second harmonic wavelength of 620 nm. We used infrared probe pulses at main wavelength of 1240 nm, whose photon energy was less than the band gap width E{sub g} = 1.12eV of silicon, and the penetration depth of probe essentially exceeded the sample thickness. Unlike many previous experiments with Ti:sapphire lasers it allowed us to probe the heated area from the rear side of the sample and obtain the data on melt depth after laser irradiation.

Bose-Einstein condensation of triplons in Ba3Cr2O8  

SciTech Connect

By performing heat capacity, magnetocaloric effect, torque magnetometry and force magnetometry measurements up to 33 T, we have mapped out the T-H phase diagram of the S = 1/2 spin dimer compound Ba{sub 3}Cr{sub 2}O{sub 8}. We found evidence for field-induced magnetic order between H{sub cl} = 12.52(2) T and H{sub c2} = 23.65(5) T, with the maximum transition temperature T{sub c} {approx} 2.7 K at H {approx} 18 T. The lower transition can likely be described by Bose-Einstein condensation of triplons theory, and this is consistent with the absence of any magnetization plateaus in our magnetic torque and force measurements. In contrast, the nature of the upper phase transition appears to be quite different as our measurements suggest that this transition is actually first order.

Microstructural characterization of as-cast biocompatible Co-Cr-Mo alloys  

SciTech Connect

The microstructure of a cobalt-base alloy (Co-Cr-Mo) obtained by the investment casting process was studied. This alloy complies with the ASTM F75 standard and is widely used in the manufacturing of orthopedic implants because of its high strength, good corrosion resistance and excellent biocompatibility properties. This work focuses on the resulting microstructures arising from samples poured under industrial environment conditions, of three different Co-Cr-Mo alloys. For this purpose, we used: 1) an alloy built up from commercial purity constituents, 2) a remelted alloy and 3) a certified alloy for comparison. The characterization of the samples was achieved by using optical microscopy (OM) with a colorant etchant to identify the present phases and scanning electron microscopy (SE-SEM) and energy dispersion spectrometry (EDS) techniques for a better identification. In general the as-cast microstructure is a Co-fcc dendritic matrix with the presence of a secondary phase, such as the M{sub 23}C{sub 6} carbides precipitated at grain boundaries and interdendritic zones. These precipitates are the main strengthening mechanism in this type of alloys. Other minority phases were also reported and their presence could be linked to the cooling rate and the manufacturing process variables and environment. - Research Highlights: {yields}The solidification microstructure of an ASTM-F75 type alloy were studied. {yields}The alloys were poured under an industrial environment. {yields}Carbides and sigma phase identified by color metallography and scanning microscopy (SEM and EDS). {yields}Two carbide morphologies were detected 'blocky type' and 'pearlite type'. {yields}Minority phases were also detected.

Alba field - middle Eocene deep-water channel in U. K. North Sea  

SciTech Connect

The Alba field is located in the Witch Ground graben between the Fladen Ground spur to the north and the Renee Ridge to the south, entirely in UKCS Block 16/26. In 1985, oil was discovered in the middle Eocene sands of the Horda formation at a depth of 6100 ft subsea. Twelve additional wells, including sidetracks, have been drilled appraise the discovery. This drilling indicates the Alba field is a stratigraphic trap covering an area of 3600 ac. The Alba sands represent a brief interruption in the hemipelagic sedimentation that dominated this part of the Witch Ground graben during the middle Eocene. Sediment was supplied intermittently from a shelf area to the northwest into a deep-water environment. Well correlations, seismic facies analysis, and core analysis indicate that these sands were deposited as part of a constructional channel/levee complex within a mud-rich, shelf-sourced submarine fan system. The cap and the updip and lateral seals to the reservoir are shale. The Alba reservoir is predominantly a homogeneous, fine-grained, unconsolidated sand. The average reservoir porosity is 33% and the average permeability is 2.8 darcys. Oil in place is estimated to be 1.1 billion bbl of 20/degrees/ API crude.

National Energy Efficiency and Conservation Policies and Programs in Developed Countries and Middle East  

E-Print Network (OSTI)

The world's economies should endeavour to ultimately reduce their energy consumption, rather than simply adjusting or optimizing their energy utilisation. The implementation of intelligent strategies, designed to manage human activities which are highly dependent on energy, should be the preferred solution to develop and achieve a sustainable and secure economy. This paper describes policies for energy conservation adopted by developed industrialized countries such as Japan, Germany, France, Britain and the US, as well as developing countries in the Middle East such as Qatar, Kuwait, Syria and the United Arab Emirates. The aim of this document will be to identify and clarify the major factors that drive the creation and implementation of energy policies, as well as the strength and weakness of each of the adopted strategies of energy conservation, including the associated risks and opportunities. The conclusion of this study will offer recommendations for the most suitable framework for determining the best practices to develop sustainable societies in Middle East region, which in turn will equip these countries to respond more efficiently to the implementation of the latest international standards, which are mandatory in order to succeed in the global business field.

Anadronous Fish Habitat Enhancement for the Middle Fork and Upper Salmon River, 1988 Annual Report.  

DOE Green Energy (OSTI)

The wild and natural salmon and steelhead populations in the Middle Fork and Upper Salmon River are at a critical low. Habitat enhancement through decreasing sediment loads, increasing vegetative cover, removing passage barriers, and providing habitat diversity is imperative to the survival of these specially adapted fish, until passage problems over the Columbia River dams are solved. Personnel from the Boise and Sawtooth National Forests completed all construction work planned for 1988. In Bear Valley, 1573 feet of juniper revetment was constructed at eleven sites, cattle were excluded from 1291 feet of streambanks to prevent bank breakdown, and a small ephemeral gully was filled with juniper trees. Work in the Upper Salmon Drainage consisted of constructing nine rock sills/weirs, two rock deflectors, placing riprap along forty feet of streambank, construction of 2.1 miles of fence on private lands, and opening up the original Valley Creek channel to provide spring chinook passage to the upper watershed. A detailed stream survey of anadromous fish habitat covering 72.0 miles of streams in the Middle Fork Sub-basin was completed.

Secondary porosity and hydrocarbon reservoirs in Lower-Middle Miocene Sandstones, southern San Joaquin basin, California  

SciTech Connect

Immature lower to middle Miocene marine sandstones constitute important reservoir rocks in many southern San Joaquin basin oil fields. Surface samples from the east and west margins of the basin and subsurface samples from Round Mountain, Belridge, and Coalinga fields were examined. These localities have undergone recurrent uplift since middle Tertiary time and maximum burial probably did not exceed 2500-3000 m. Diagenetic features common to east- and west-side sandstones include phosphatization, early calcite cementation, pressure solution and replacement of silicate grains by calcite cement, framework grain dissolution and creation of secondary porosity, and replacement of biotite and hornblende by chlorite. Differences include recrystallization and dolomitization of early calcite on the west side, and massive carbonate dissolution followed by extensive crushing and pressure solution of silicate grains and late replacement of plagioclase by calcite and calcite by hematite on the east side. Replacement of biotite by chlorite occurred only in the deepest samples on either side of the basin. Basinwide differences in diagenesis reflect different tectonic evolutions between east and west sides of the basin. Local variations in diagenetic patterns are pronounced in all areas and are controlled by initial sediment composition. For example, in one core from Coalinga early calcite cement, recrystallized calcite cement, and dolomitized calcite cement are interbedded over the 60-m interval sampled. Hydrocarbons in all samples reside mainly in secondary pores created by cement and framework-grain dissolution, underscoring the importance of diagenesis in creating reservoirs in this basin.

Need for refining capacity creates opportunities for producers in Middle East  

SciTech Connect

Oil industry interest in refining has revived in the past few years in response to rising oil consumption. The trend creates opportunities, for countries in the Middle East, which do not own refining assets nearly in proportion to their crude oil reserved. By closing this gap between reserves and refining capacity, the countries can ease some of the instability now characteristic of the oil market. Some major oil producing countries have begun to move downstream. During the 1980s, Venezuela, Kuwait, Saudi Arabia, Libya, and other members of the Organization of Petroleum Exporting Countries acquired refining assets through direct total purchase or joint ventures. Nevertheless, the oil industry remains largely unintegrated, with the Middle East holding two thirds of worldwide oil reserves but only a small share downstream. As worldwide refining capacity swings from a period of surplus toward one in which the need for new capacity will be built. The paper discusses background of the situation, shrinking surplus, investment requirements, sources of capital, and shipping concerns.

Characterization of a Middle Distillate Oil from a Coal hydroliquefaction Plant  

Science Conference Proceedings (OSTI)

In this article, a middle distillate oil obtained from a coal hydroliquefaction pilot plant was characterized by modern analytical instruments. First, using {sup 1}H and {sup 13}C nuclear magnetic resonance, the distribution of hydrogen and carbon atoms were obtained, and the presence of configurations such as long aliphatic carbon chains, alkyl-substituted aromatic ring, and partially hydrogenated aromatics in the middle distillate oil was found. Then the oil was separated into three fractions: saturates, aromatics, and polars by neutral silica gel liquid chromatography, and the detailed compositions of saturates and aromatics were respectively analyzed by gas chromatography-mass spectrometry. The results show that the aromatics fraction is the most abundant one in this oil, but they are not normal aromatics and mainly consist of dicyclic-, tricyclic-, and tetracyclic-partially hydrogenated aromatics with carbon atom numbers from C10-C21, such as tetralin, alkyl-substituted tetralin, hydrophenanthrene, hydroanthracene, hydropyrene, and so on. Saturates mainly comprise n-C12-C27 alkanes. These results are of significance for the further processing and marketing of this oil.

Super-giant oil fields and future prospects in the Middle East  

Science Conference Proceedings (OSTI)

Upper Jurassic carbonates, Lower Cretaceous sands, Lower Cretaceous carbonates and Tertiary carbonates of the Middle East contain more than 50% of the worlds oil. Our area of interest covers SE Turkey and Syria in the north to the borders of Yemen and Oman in the south, and from the Red Sea across Saudi Arabia, the Emirates and the Arabian/Persian Gulf to Iran in the East. There are over 80 fields in this region with over 1 billion barrels of recoverable reserves. Yet only around 30,000 wells have been drilled in this territory. Regional structure and stratigraphy are discussed within the context of three major plays in the region as well as a new play in the Permo-Carboniferous. Numerous opportunities are available and countries such as Iraq and Iran may one day open their doors more to the industry than is presently the case. The dramatic petroleum geology of the region will stamp its influence on the nature of business and opportunities for years to come. While fiscal systems here already offer some of the toughest terms in the world, future deals in the more prolific areas will be even tougher. But, the economies of Middle Eastern scale will provide some of the great mega-opportunities of future international exploration.

Cyclic nanoindentation studies on CrN thin films prepared by RF sputtering on Zr-based metallic glass  

Science Conference Proceedings (OSTI)

Cyclic nanoindentation tests were carried out to study the influence of the chromium nitride thin films on the mechanical properties of Zr-based metallic glass. Chromium nitride thin coatings have been deposited on Zr{sub 50}Cu{sub 40}Al{sub 10} metallic glass substrate by RF sputtering. The deposition process was done at room temperature under nitrogen reactive gas using a metallic chromium target. The CrN films have a thickness of 300 nm. Several cyclic nanoindentation measurements were conducted on CrN films and Zr{sub 50}Cu{sub 40}Al{sub 10} metallic glass substrate samples at various loading rate values. We have found that the coated metallic glass sample shows high mechanical properties such as hardness and reduced elastic modulus. Cyclic nanoindentation results show a hardening behaviour for these CrN coatings. Moreover, the CrN coated on Zr-based metallic glass was found to have a high value of resistance to crack propagation, as being analysed through the SEM pictures of the residual Vickers indentation impressions.

Influence of alloy content and a cerium surface treatment on the oxidation behavior of Fe-Cr ferritic stainless steels  

SciTech Connect

The cost of solid oxide fuel cells (SOFC) can be significantly reduced by using interconnects made from ferritic stainless steels. In fact, several alloys have been developed specifically for this application (Crofer 22APU and Hitachi ZMG323). However, these steels lack environmental stability in SOFC environments, and as a result, degrade the performance of the SOFC. A steel interconnect can contribute to performance degradation through: (i) Cr poisoning of electrochemically active sites within the cathode; (ii) formation of non-conductive oxides, such as SiO2 or Al2O3 from residual or minor alloying elements, at the base metal-oxide scale interface; and/or (iii) excessive oxide scale growth, which may also retard electrical conductivity. Consequently, there has been considerable attention on developing coatings to protect steel interconnects in SOFC environments and controlling trace elements during alloy production. Recently, we have reported on the development of a Cerium surface treatment that improves the oxidation behavior of a variety alloys, including Crofer 22APU [1-5]. Initial results indicated that the treatment may improve the performance of Crofer 22APU for SOFC application by: (i) retarding scale growth resulting in a thinner oxide scale; and (ii) suppressing the formation of a deleterious continuous SiO2 layer that can form at the metal-oxide scale interface in materials with high residual Si content [5]. Crofer 22 APU contains Fe-22Cr-0.5Mn-0.1Ti (weight percent). Depending on current market prices and the purity of raw materials utilized for ingot production, Cr can contribute upwards of 90 percent of the raw materials cost. The present research was undertaken to determine the influence of Cr content and minor element additions, especially Ti, on the effectiveness of the Ce surface treatment. Particular emphasis is placed on the behavior of low Cr alloys.

The Potential Uses of Commercial Satellite Imagery in the Middle East  

Science Conference Proceedings (OSTI)

It became clear during the workshop that the applicability of commercial satellite imagery to the verification of future regional arms control agreements is limited at this time. Non-traditional security topics such as environmental protection, natural resource management, and the development of infrastructure offer the more promising applications for commercial satellite imagery in the short-term. Many problems and opportunities in these topics are regional, or at least multilateral, in nature. A further advantage is that, unlike arms control and nonproliferation applications, cooperative use of imagery in these topics can be done independently of the formal Middle East Peace Process. The value of commercial satellite imagery to regional arms control and nonproliferation, however, will increase during the next three years as new, more capable satellite systems are launched. Aerial imagery, such as that used in the Open Skies Treaty, can also make significant contributions to both traditional and non-traditional security applications but has the disadvantage of requiring access to national airspace and potentially higher cost. There was general consensus that commercial satellite imagery is under-utilized in the Middle East and resources for remote sensing, both human and institutional, are limited. This relative scarcity, however, provides a natural motivation for collaboration in non-traditional security topics. Collaborations between scientists, businesses, universities, and non-governmental organizations can work at the grass-roots level and yield contributions to confidence building as well as scientific and economic results. Joint analysis projects would benefit the region as well as establish precedents for cooperation.

Use of a dynamic simulation model to understand nitrogen cycling in the middle Rio Grande, NM.  

Science Conference Proceedings (OSTI)

Water quality often limits the potential uses of scarce water resources in semiarid and arid regions. To best manage water quality one must understand the sources and sinks of both solutes and water to the river system. Nutrient concentration patterns can identify source and sink locations, but cannot always determine biotic processes that affect nutrient concentrations. Modeling tools can provide insight into these large-scale processes. To address questions about large-scale nitrogen removal in the Middle Rio Grande, NM, we created a system dynamics nitrate model using an existing integrated surface water--groundwater model of the region to evaluate our conceptual models of uptake and denitrification as potential nitrate removal mechanisms. We modeled denitrification in groundwater as a first-order process dependent only on concentration and used a 5% denitrification rate. Uptake was assumed to be proportional to transpiration and was modeled as a percentage of the evapotranspiration calculated within the model multiplied by the nitrate concentration in the water being transpired. We modeled riparian uptake as 90% and agricultural uptake as 50% of the respective evapotranspiration rates. Using these removal rates, our model results suggest that riparian uptake, agricultural uptake and denitrification in groundwater are all needed to produce the observed nitrate concentrations in the groundwater, conveyance channels, and river as well as the seasonal concentration patterns. The model results indicate that a total of 497 metric tons of nitrate-N are removed from the Middle Rio Grande annually. Where river nitrate concentrations are low and there are no large nitrate sources, nitrate behaves nearly conservatively and riparian and agricultural uptake are the most important removal mechanisms. Downstream of a large wastewater nitrate source, denitrification and agricultural uptake were responsible for approximately 90% of the nitrogen removal.

Microstructural evolution during solution treatment of Co-Cr-Mo-C biocompatible alloys  

SciTech Connect

Three different Co-Cr-Mo-C alloys conforming to ASTM F75 standard were poured in an industrial environment and subjected to a conventional solution treatment at 1225 Degree-Sign C for several time intervals. The microstructural changes and transformations were studied in each case in order to evaluate the way in which treatment time influences the secondary phase fraction and clarify the microstructural changes that could occur. To assess how treatment time affects microstructure, optical microscopy and image analyzer software, scanning electron microscopy and energy dispersion spectrometry analysis were employed. The main phases detected in the as-cast state were: {sigma}-phase, M{sub 6}C, and M{sub 23}C{sub 6} carbides. The latter presented two different morphologies, blocky type and lamellar type. Despite being considered the most detrimental feature to mechanical properties, {sigma}-phase and lamellar carbides dissolution took place in the early stages of solution treatment. M{sub 23}C{sub 6} carbides featured two different behaviors. In the alloy obtained by melting an appropriate quantity of alloyed commercial materials, a decrease in size, spheroidization and transformation into M{sub 6}C carbides were simultaneously observed. In the commercial ASTM F75 alloy, in turn, despite being the same phase, only a marked decrease in precipitates size was noticed. These different behaviors could be ascribed to the initial presence of other phases in the alloy obtained from alloyed materials, such as {sigma}-phase and 'pearlitic' carbides, or to the initial precipitate size which was much larger in the first than in the commercial ASTM F75 alloy studied. M{sub 6}C carbides dissolved directly in the matrix as they could not be detected in samples solution-treated for 15 min. - Highlights: Black-Right-Pointing-Pointer Three different Co-Cr-Mo alloys were poured under an industrial environment.

Nature of =~SiOCrO(2)CI And (=~SiO)(2)CrO(2) Sites Prepared By Grafting CrO(2)CI(2) Onto Silica  

SciTech Connect

The room-temperature reaction between chromyl chloride and Sylopol 952 silicas pretreated at 200, 450, and 800 C was investigated using IR, XANES, and EXAFS spectroscopy, as well as by DFT modeling. On the silicas pretreated at 200 and 450 C, the structurally uniform sites formed by the reaction with one surface hydroxyl group are described as {triple_bond}SiOCrO{sub 2}Cl. Unreacted silanols persist on these silicas even in the presence of excess CrO{sub 2}Cl{sub 2}, and on the silica pretreated at 200 C some participate in hydrogen bonding with the grafted monochlorochromate sites. On the silica pretreated at 800 C, both {triple_bond}SiOCrO{sub 2}Cl and ({triple_bond}SiO){sub 2}CrO{sub 2} sites are formed. The latter are produced despite the absence of hydrogen-bonded hydroxyl pairs on the support. The origin of the chromate sites is proposed to be the reaction between CrO{sub 2}Cl{sub 2} and hydroxyl-substituted siloxane 2-rings. These rings are likely formed at 800 C by condensation between a pair of vicinal silanols in which one of the silanols is also a member of a geminal pair.

Factors Affecting the Hydrogen Embrittlement Resistance of Ni-Cr-Mn-Nb Welds  

DOE Green Energy (OSTI)

Nickel based alloys are often welded with argon/hydrogen shielding gas mixtures to minimize oxidation and improve weld quality. However, shielding gas mixtures with {ge} 1% hydrogen additions can result in hydrogen concentrations greater than 5 wt. ppm in the weld metal and reduce ductility via hydrogen embrittlement. For the conditions investigated, the degree of hydrogen embrittlement is highly variable between 5 and 14 wt. ppm. investigation of hydrogen embrittlement of EN82H GTAW welds via tensile testing, light microscopy, transmission electron microscopy, orientation imaging microscopy, and thermal desorption spectroscopy shows that this variability is due to the inhomogeneous microstructure of the welds, the presence of recrystallized grains, and complex residual plastic strains. Specifically, research indicates that high residual strains and hydrogen trapping lower the ductility of Ni-Cr-Mn-Nb weld metal when dissolved hydrogen concentrations are greater than 5 wt. ppm. The inhomogeneous microstructure contains columnar dendritic, cellular dendritic, and recrystallized grains. The decreased tensile ductility observed in embrittled samples is recovered by post weld heat treatments that decrease the bulk hydrogen concentration below 5 wt. ppm.

Overview of a Welding Development Program for a Ni-Cr-Mo-Gd Alloy  

Science Conference Proceedings (OSTI)

The National Spent Nuclear Fuel Program (NSNFP), located at the Idaho National Laboratory, coordinates and integrates management and disposal of U.S. Department of Energy-owned spent nuclear fuel. These management functions include using the DOE standardized canister for packaging, storage, treatment, transport, and long-term disposal in the Yucca Mountain Repository. Nuclear criticality must be prevented in the postulated event where a waste package is breached and water (neutron moderator) is introduced into the waste package. Criticality control will be implemented by using a new, weldable, corrosion-resistant, neutron-absorbing material to fabricate the welded structural inserts (fuel baskets) that will be placed in the standardized canister. The new alloy is based on the Ni-Cr-Mo alloy system with a gadolinium addition. Gadolinium was chosen as the neutron absorption alloying element because of its high thermal neutron absorption cross section. This paper describes a weld development program to qualify this new material for American Society of Mechanical Engineers (ASME) welding procedures, develop data to extend the present ASME Code Case (unwelded) for welded construction, and understand the weldability and microstructural factors inherent to this alloy.

Modeling solar thermochemical splitting of CO2 using metal oxide and a CR5.  

SciTech Connect

A two-dimensional, multi-physics computational model based on the finite-element method is developed for simulating the process of solar thermochemical splitting of carbon dioxide (CO{sub 2}) using ferrites (Fe{sub 3}O{sub 4}/FeO) and a counter-rotating-ring receiver/recuperator or CR5, in which carbon monoxide (CO) is produced from gaseous CO{sub 2}. The model takes into account heat transfer, gas-phase flow and multiple-species diffusion in open channels and through pores of the porous reactant layer, and redox chemical reactions at the gas/solid interfaces. Results (temperature distribution, velocity field, and species concentration contours) computed using the model in a case study are presented to illustrate model utility. The model is then employed to examine the effects of injection rates of CO{sub 2} and argon neutral gas, respectively, on CO production rate and the extent of the product-species crossover.

Using CrAIN Multilayer Coatings to Improve Oxidation Resistance of Steel Interconnects for Solid Oxide Fuel Cell Stacks  

Science Conference Proceedings (OSTI)

The requirements of low cost and high-tempurature corrosion resistance for bipolar interconnect plates in solid oxide fuel cell stacks has directed attention to the use of metal plates with oxidation resistant coatings. We have investigatedt he performance of steel plates with multilayer coatings consisting of CrN for electrical conductivity and CrAIN for oxidation resistance. The coatings were deposited usin large area filterd arc deposition technolgy, and subsequently annealed in air for up to 25 hours at 800 degrees celsius. The composition, structer and morphology of the coated plates were characterized using RBS, nuclear reaction analysis, AFM and TEM techniques. By altering the architecture of the layers within the coatings, the rate of oxidation was reduced by more than an order of magnitute. Electrical resistance was measured at room temperature.

Recent progress in nanostructured multiferroic Bi{sub 2}FeCrO{sub 6} thin films  

Science Conference Proceedings (OSTI)

We report the latest progress on the growth and characterization of Bi{sub 2}FeCrO{sub 6} (BFCO), a recently discovered multiferroic system. BFCO thin films and nanostructures exhibit exceptional multiferroic properties at room temperature. The growth of pure BFCO thin films on STO substrates is possible only in a narrow window of deposition parameters (i.e., Oxygen pressure pO{sub 2}=1.2 Multiplication-Sign 10{sup -2} mbar and around a substrate temperature T{sub S}=680 Degree-Sign C). The epitaxial growth stabilizes the metastable single phase of this material and promotes the Fe/Cr cation ordering in both thin films and nanostructures. This cationic ordering which is responsible for good magnetic properties of BFCO is also at the origin of pronounced photovoltaic (PV) properties observed in the epitaxial films grown on STO substrates. The results indicate that the ferroelectric polarization plays a dominant role in the observed PV effect. - Graphical abstract: (Top) Crystal structure of BFCO thin films deposited on (1 1 1)-oriented SrTiO3:Nb substrates and direct evidence of the presence of cationic ordering Fe/Cr in the films.

Experimental measurement of the persistence of permeability reduction in porous media treated with xanthan/Cr(III) gel systems  

SciTech Connect

This paper reports on a series of long-term experiments that was conducted to determine the persistence of flow resistance in unconsolidated sandpacks treated with xanthum/Cr(III) gels. Gels were prepared with 2,000 ppm xanthum and Cr(III) concentrations from 25 to 200 ppm. These systems exhibit various degrees of swelling or syneresis. The experiments were conducted by first allowing a gel to set up in a sandpack and then continuously flushing the sandpack with brine for up to 4 months at a constant pressure drop of 13.3 psi/ft. Flow rate was monitored to calculate permeability changes with time. Flow experiments indicated that the measurement of swelling and syneresis in bulk-gel tests is not a good predictor of gel response in unconsolidated sandpacks. Excellent permeability reduction was obtained in sandpacks when gels that exhibited 35% to 60% reduction in volume in bulk tests owing to syneresis were used. Gels were most effective at retaining flow resistance in the range of 35 to 75 ppm Cr(III), where the sandpacks regained {lt} 0.1% of their original 4,000 md permeability during the experiments. These observations were supported by experiments in which the pH of the injected brine was varied between 3.0 and 6.5. The swelling tests on the bulk gel indicated that permeability would decrease as pH increased and would increase as pH decreased.

Cr(VI) adsorption on functionalized amorphous and mesoporous silica from aqueous and non-aqueous media  

Science Conference Proceedings (OSTI)

A mesoporous silica (SBA-15) and amorphous silica (SG) have been chemically modified with 2-mercaptopyridine using the homogeneous route. This synthetic route involved the reaction of 2-mercaptopyridine with 3-chloropropyltriethoxysilane prior to immobilization on the support. The resulting material has been characterized by powder X-ray diffraction, nitrogen gas sorption, FT-IR and MAS NMR spectroscopy, thermogravimetry and elemental analysis. The solid was employed as a Cr(VI) adsorbent from aqueous and non-aqueous solutions at room temperature. The effect of several variables (stirring time, pH, metal concentration and solvent polarity) has been studied using the batch technique. The results indicate that under the optimum conditions, the maximum adsorption value for Cr(VI) was 1.83 {+-} 0.03 mmol/g for MP-SBA-15, whereas the adsorption capacity of the MP-SG was 0.86 {+-} 0.02 mmol/g. On the basis of these results, it can be concluded that it is possible to modify chemically SBA-15 and SG with 2-mercaptopyridine and to use the resulting modified silicas as effective adsorbents for Cr(VI)

Comparison of Crevice Corrosion of Fe-Based Amorphous Metal and Crystalline Ni-Cr-Mo Alloy  

SciTech Connect

The crevice corrosion behaviors of an Fe-based bulk metallic glass alloy (SAM1651) and a Ni-Cr-Mo crystalline alloy (C-22) were studied in 4M NaCl at 100 C with cyclic potentiodynamic polarization and constant potential tests. The corrosion damage morphologies, corrosion products and the compositions of corroded surfaces of these two alloys were studied with optical 3D reconstruction, Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and Auger Electron Spectroscopy (AES). It was found that the Fe-based bulk metallic glass (amorphous alloy) SAM1651 had a more positive breakdown potential and repassivation potential than crystalline alloy C-22 in cyclic potentiodynamic polarization tests and required a more positive oxidizing potential to initiate crevice corrosion in constant potential test. Once crevice corrosion initiated, the corrosion propagation of C-22 was more localized near the crevice border compared to SAM1651, and SAM1651 repassivated more readily than C-22. The EDS results indicated that the corrosion products of both alloys contained high amount of O and were enriched in Mo and Cr. The AES results indicated that a Cr-rich oxide passive film was formed on the surfaces of both alloys, and both alloys were corroded congruently.

Reactions of Ethylidene on a Model Chromia Surface: 1 1-Dichloroethane on Stoichiometric alpha-Cr2O3 (1012)  

SciTech Connect

The reaction of CH{sub 3}CHCl{sub 2} over the nearly-stoichiometric {alpha}-Cr{sub 2}O{sub 3} (10{sub {bar 1}} > 2) surface produces an ethylidene intermediate that yields primarily gas phase CH{sub 2}{double_bond}CH{sub 2} and surface chlorine adatoms; however, trace amounts of HC{triple_bond}CH, CH{sub 3}CH{sub 3}, H{sub 2} and CH{sub 3}CH{double_bond}CHCH{sub 3} are also observed. A rate-limiting intramolecular isomerization (2,1-hydrogen shift) in the surface ethylidene species produces gas phase CH{sub 2}{double_bond}CH{sub 2}. The chlorine freed from the dissociation of CH{sub 3}CHCl{sub 2} binds at the five-coordinate surface Cr{sup 3+} sites on the stoichiometric surface, completing the octahedral coordination sphere, and inhibits the surface chemistry by simple site blocking. No surface carbon deposition is observed from the thermal reaction of 1,1-dichloroethane under the conditions of this study, demonstrating that the ethylidene intermediate is not a primary coke forming intermediate over (10{sub {bar 1}} > 2) facets of {alpha}-Cr{sub 2}O{sub 3} under the conditions of this study.

Properties of molecular beam epitaxy grown Eu{sub x}(transition metal){sub y} films (transition metals: Mn, Cr)  

Science Conference Proceedings (OSTI)

The electronic and crystallographic structures, as well as the magnetic properties, of Eu{sub x}(transition metal){sub y} (transition metals: Mn, Cr) thin films grown by molecular beam epitaxy were studied. Relative changes of the Eu/Mn and Eu/Cr ratios derived from the XPS lines, as well as x-ray reflectivity, indicate mixing of the Eu/Mn and Eu/Cr layers. Valency transitions from Eu{sup 2+} to Eu{sup 3+} were observed in both systems for most studied stoichiometries. A transition to a magnetically ordered phase was observed at 15 K, 40 K, and 62 K for selected films in the Eu-Mn system, and at 50 K for the film with a Eu/Cr ratio of 0.5.

Authoritative discourse in the middle school mathematics classroom: a case study  

E-Print Network (OSTI)

According to the National Council of Teachers of Mathematics (NCTM) standard of communication, ??Instructional programs from pre-kindergarten through grade 12 should enable all students to...communicate their mathematical thinking coherently and clearly to peers, teachers, and others?? and students need to learn ??what is acceptable as evidence in mathematics?? (NCTM, 2000, p. 60). But do teachers have a clear understanding of what is acceptable or do they believe that the only acceptable explanations are the ones that they themselves gave to the students? Can teachers accept alternative forms of explanation and methods of solution as mathematically accurate or do they want students to simply restate the teachers?? understandings of mathematics and the problem? The focus of this dissertation is the authoritative discourse practices of classroom teachers as they relate to individual students and large and small groups of students. In this case study, I examine the interactions in one eighth-grade mathematics classroom and the possible sharing of mathematical authority and development of mathematical agency that take place via the teacher??s uses of authoritative discourse. A guiding objective of this research was to examine the ways a teacher??s discursive practices were aligned with her pedagogical intentions. The teacher for this study was an experienced eighth-grade mathematics teacher at a rural Central Texas middle school. The teacher was a participant in the Middle School Mathematics Project at Texas A&M University. Results of an analysis of the discourse of six selected classes were combined with interview and observation data and curriculum materials to inform the research questions. I found that through the teacher??s regular use of authoritative discursive devices, mathematical authority was infrequently shared. Also the teacher??s uses of authoritative discourse helped create an environment where mathematical agency was not encouraged or supported. The teacher??s use of various discursive devices helped establish and maintain a hierarchy of mathematical authority with students at the lowest level reliant on others for various mathematical decisions.

Giant magnetoresistive structures based on CrO{sub 2} with epitaxial RuO{sub 2} as the spacer layer  

Science Conference Proceedings (OSTI)

Epitaxial ruthenium dioxide (RuO{sub 2})/chromium dioxide(CrO{sub 2}) thin film heterostructures have been grown on (100)-TiO{sub 2} substrates by chemical vapor deposition. Both current-in-plane (CIP) and current-perpendicular-to-plane (CPP) giant magnetoresistive stacks were fabricated with either Co or another epitaxial CrO{sub 2} layer as the top electrode. The Cr{sub 2}O{sub 3} barrier, which forms naturally on CrO{sub 2} surfaces, is no longer present after the RuO{sub 2} deposition, resulting in a highly conductive interface that has a resistance at least four orders of magnitude lower. However, only very limited magnetoresistance (MR) was observed. Such low MR is due to the appearance of a chemically and magnetically disordered layer at the CrO{sub 2} and RuO{sub 2} interfaces when Cr{sub 2}O{sub 3} is transformed into rutile structures during its intermixing with RuO{sub 2}.

High-energy emission from pulsars in polar-cap models with CR-induced cascades  

E-Print Network (OSTI)

For a subclass of polar-cap models based on electromagnetic cascades induced by curvature radiation (CR) we calculate broad-band high-energy spectra of pulsed emission expected for classical and millisecond pulsars. The spectra are a combination of curvature and synchrotron components. The spectrum of curvature component breaks at 150MeV, and neither its slope nor level below this energy are compatible with phase-averaged spectra of pulsed X-ray emission inferred from observations. Spectral properties in the combined energy range of ROSAT and ASCA (0.1 - 10 keV) depend upon the location of cyclotron turnover energy epsilon_ct=\\hbar{e B \\over m_e c} /sin(psi) in the synchrotron component. Unlike in outer-gap models, the available range of pitch angles psi is rather narrow and confined to low values. For classical pulsars, a gradual turnover begins already at 1MeV, and the level of the synchrotron spectrum decreases. At 10keV the curvature component eventually takes over, but with photon index alpha = 2/3, in disagreement with observations. For millisecond pulsars, the X-ray spectra are dominated by synchrotron component with alpha \\simeq 1.5, and a sharp turnover into alpha \\simeq -1 at epsilon_ct \\sim 100eV. Relations of pulsed luminosity L_X to spin-down luminosity \\edot are presented for classical and millisecond pulsars. We conclude that spectral properties and fluxes of pulsed non-thermal X-ray emission of some objects, like the Crab or the millisecond pulsar B1821-24, pose a challenge to the subclass of polar-cap models based on curvature and synchrotron radiation alone.

Laser welding and post weld treatment of modified 9Cr-1MoVNb steel.  

SciTech Connect

Laser welding and post weld laser treatment of modified 9Cr-1MoVNb steels (Grade P91) were performed in this preliminary study to investigate the feasibility of using laser welding process as a potential alternative to arc welding methods for solving the Type IV cracking problem in P91 steel welds. The mechanical and metallurgical testing of the pulsed Nd:YAG laser-welded samples shows the following conclusions: (1) both bead-on-plate and circumferential butt welds made by a pulsed Nd:YAG laser show good welds that are free of microcracks and porosity. The narrow heat affected zone has a homogeneous grain structure without conventional soft hardness zone where the Type IV cracking occurs in conventional arc welds. (2) The laser weld tests also show that the same laser welder has the potential to be used as a multi-function tool for weld surface remelting, glazing or post weld tempering to reduce the weld surface defects and to increase the cracking resistance and toughness of the welds. (3) The Vicker hardness of laser welds in the weld and heat affected zone was 420-500 HV with peak hardness in the HAZ compared to 240 HV of base metal. Post weld laser treatment was able to slightly reduce the peak hardness and smooth the hardness profile, but failed to bring the hardness down to below 300 HV due to insufficient time at temperature and too fast cooling rate after the time. Though optimal hardness of weld made by laser is to be determined for best weld strength, methods to achieve the post weld laser treatment temperature, time at the temperature and slow cooling rate need to be developed. (4) Mechanical testing of the laser weld and post weld laser treated samples need to be performed to evaluate the effects of laser post treatments such as surface remelting, glazing, re-hardening, or tempering on the strength of the welds.

Oxbow Conservation Area; Middle Fork John Day River, Annual Report 2003-2004.  

DOE Green Energy (OSTI)

In early 2001, the Confederated Tribes of Warm Springs, through their John Day Basin Office, concluded the acquisition of the Oxbow Ranch, now know as the Oxbow Conservation Area (OCA). Under a memorandum of agreement with the Bonneville Power Administration (BPA), the Tribes are required to provided BPA an 'annual written report generally describing the real property interests in the Project, HEP analyses undertaken or in progress, and management activities undertaken or in progress'. The project during 2003 was crippled due to the aftermath of the BPA budget crisis. Some objectives were not completed during the first half of this contract because of limited funds in the 2003 fiscal year. The success of this property purchase can be seen on a daily basis. Water rights were utilized only in the early, high water season and only from diversion points with functional fish screens. After July 1, all of the OCA water rights were put instream. Riparian fences on the river, Ruby and Granite Boulder creeks continued to promote important vegetation to provide shade and bank stabilization. Hundreds of willow, dogwood, Douglas-fir, and cottonwood were planted along the Middle Fork John Day River. Livestock grazing on the property was carefully managed to ensure the protection of fish and wildlife habitat, while promoting meadow vigor and producing revenue for property taxes. Monitoring of property populations, resources, and management activities continued in 2003 to build a database for future management of this and other properties in the region.

The Economics of Solar Thermal Electricity For Europe, North Africa, and the Middle East  

E-Print Network (OSTI)

A climate crisis is inevitable unless developing countries limit carbon emissions from the power sector in the near future. This will happen only if the costs of lowcarbon power production become competitive with fossil fuel power. We focus on a leading candidate for investment: solar thermal or concentrating solar power (CSP), a commercially available technology that uses direct sunlight and mirrors to boil water and drive conventional steam turbines. Solar thermal power production in North Africa and the Middle East could provide enough power to Europe to meet the needs of 35 million people by 2020. We compute the subsidies needed to bring CSP to financial parity with fossil-fuel alternatives. They conclude that large-scale deployment of CSP is attainable with subsidy levels that are modest, given the planetary stakes. By the end of the program, unsubsidized CSP projects are likely to be competitive with coal- and gasbased power production in Europe. The question is not whether CSP is feasible but whether programs using CSP

Ammonite zonation in condensed zone, middle Ozan formation (Taylor group, upper Cretaceous) in Northeast Texas

Recognition of condensed zones is important because they may be marker horizons that are useful in exploration. Such a zone is demonstrated by the occurrence of ammonites belonging to 12 species and 9 genera from the middle Ozan Formation (lower Taylor Marl) in northeast Texas. The 1-foot (0.3-m) thick bed of bioturbated glauconitic biomicrite contains many specimens of disarticulated vertebrates, molluscs, remanie' fossils (blackened phosphatic internal molds), and hiatus concretions. Four of 6 midcontinent ammonite range zones proposed by Cobban and others appear to be represented in the fauna, in ascending order, by Baculites aquilaensis Reeside, Delawarella delawarensis (Morton) (= zones of two unnamed species of Baculites), Baculites obtusus Meek, and Trachyscaphites spiniger porchi Adkins (=zones of Baculites mclearni and B. asperiformis). Young may be correct in assuming that the occurrence of Delawarella delawarensis and Baculites aquilaensis in the Ozan Formation may mean that rocks of the upper Austin Group and parts of the lower Taylor Group are the same age. If correlation with the midcontinent zonation is correct, then the sediments that formed the condensed zone slowly accumulated from 81 to 79 m.y. (mid early Campanian to early late Campanian). Several species of the fauna are preserved as both normal and remanie' fossils, indicating that members of these species lived in the area for an extended period of time, perhaps as a relict fauna. The fauna includes a mixture of cosmopolitan and endemic species (indicating open shelf environment) with several types of heteromorphs (indicating moderate water depths).

Integrative curriculum reform, domain dependent knowing, and teachers` epistemological theories: Implications for middle-level teaching  

Science Conference Proceedings (OSTI)

Integrative curriculum as both a theoretical construct and a practical reality, and as a theme-based, problem-centered, democratic way of schooling, is becoming more widely considered as a feasible alternative to traditional middle-level curricula. Importantly for teaching and learning, domain dependence requires teachers to view one area of knowledge as fully interdependent with other areas of knowledge during the learning process. This requires teachers to adopt personal epistemological theories that reflect integrative, domain dependent knowing. This study explored what happened when teachers from highly traditional domain independent school settings encountered an ambitious college-level curriculum project that was designed to help the teachers understand the potential that integrative, domain dependent teaching holds for precollege settings. This study asked: What influence does an integrative, domain dependent curriculum project have on teachers` domain independent, epistemological theories for teaching and learning? Finding an answer to this question is essential if we, as an educational community, are to understand how integrative curriculum theory is transformed by teachers into systemic curriculum reform. The results suggest that the integrative curriculum project that teachers participated in did not explicitly alter their classroom practices in a wholesale manner. Personal epistemological theories of teachers collectively precluded teachers from making any wholesale changes in their individual classroom teaching. However, teachers became aware of integrative curriculum as an alternative, and they expressed interest in infusing integrative practices into their classrooms as opportunities arise.

Silurian shale origin for light oil, condensate, and gas in Algeria and the Middle East  

SciTech Connect

Two of the largest gas fields in the world, Hasi R'Mel, Algeria and North Dome, Qatar, also contain substantial condensate and light oil reserves. Gas to source rock geochemical correlation is difficult due to the paucity of molecular parameters in the former although stable isotope composition is invaluable. However, by correlating source rocks with light oils and condensates associated with gas production using traditional geochemical parameters such as biomarkers and isotopes, a better understanding of the origin of the gas is achieved. Much of the crude oil in the Ghadames/Illizi Basins of Algeria has long been thought to have been generated from Silurian shales. New light oil discoveries in Saudi Arabia have also been shown to originate in basal euxinic Silurian shales. Key sterane and terpane biomarkers as well as the stable carbon isotopic compositions of the C15+ saturate and aromatic hydrocarbon fractions allow for the typing of Silurian-sourced, thermally mature light oils in Algeria and the Middle East. Even though biomarkers are often absent due to advanced thermal maturity, condensates can be correlated to the light oils using (1) carbon isotopes of the residual heavy hydrocarbon fractions, (2) light hydrocarbon distributions (e.g., C7 composition), and (3) compound specific carbon isotopic composition of the light hydrocarbons. The carbon isotopes of the C2-C4 gas components ran then be compared to the associated condensate and light oil isotopic composition.

The effect of f[subscript O2] on the partitioning and valence of V and Cr in garnet/melt pairs and the relation to terrestrial mantle V and Cr content  

Science Conference Proceedings (OSTI)

Chromium and vanadium are stable in multiple valence states in natural systems, and their distribution between garnet and silicate melt is not well understood. Here, the partitioning and valence state of V and Cr in experimental garnet/melt pairs have been studied at 1.8-3.0 GPa, with variable oxygen fugacity between IW-1.66 and the Ru-RuO{sub 2} (IW+9.36) buffer. In addition, the valence state of V and Cr has been measured in several high-pressure (majoritic garnet up to 20 GPa) experimental garnets, some natural megacrystic garnets from the western United States, and a suite of mantle garnets from South Africa. The results show that Cr remains in trivalent in garnet across a wide range of oxygen fugacities. Vanadium, on the other hand, exhibits variable valence state from 2.5 to 3.7 in the garnets and from 3.0 to 4.0 in the glasses. The valence state of V is always greater in the glass than in the garnet. Moreover, the garnet/melt partition coefficient, D(V), is highest when V is trivalent, at the most reduced conditions investigated (IW-1.66 to FMQ). The V{sup 2.5+} measured in high P-T experimental garnets is consistent with the reduced nature of those metal-bearing systems. The low V valence state measured in natural megacrystic garnets is consistent with f{sub O{sub 2}} close to the IW buffer, overlapping the range of f{sub O{sub 2}} measured independently by Fe{sup 2+}/Fe{sup 3+} techniques on similar samples. However, the valence state of V measured in a suite of mantle garnets from South Africa is constant across a 3 log f{sub O{sub 2}} unit range (FMQ-1.8 to FMQ-4.5), suggesting that the valence state of V is controlled by the crystal chemistry of the garnets rather than f{sub O{sub 2}} variations. The compatibility of V and Cr in garnets and other deep mantle silicates indicates that the depletion of these elements in the Earth's primitive upper mantle could be due to partitioning into lower mantle phases as well as into metal.

Aeolian Delivery of Organic Matter to a Middle Permian Deepwater Ramp  

E-Print Network (OSTI)

Windblown dust is a significant source of sediment and organic matter for many basins, but its influence on ancient basins can be difficult to detect and quantify. We quantified the biomarker content, including n-alkanes, hopanes, and steranes of the Brushy Canyon Formation sandstones and siltstones to evaluate the significance of windblown dust in delivery of sediment and terrestrial organic matter to the Middle Permian Delaware Basin. Ramp siltstones of the basin have been interpreted as representing deposits of unconfined low-density turbidity currents or "aeolo-marine" sediments. We analyzed the organic contents of five samples of channel-confined turbiditic sandstones and siltstones and five samples of ramp siltstones outcropping in the Guadalupe Mountains National Park, West Texas, to estimate the relative proportions of terrestrial and marine organic matter in the two types of host rocks. The total organic carbon content of all samples varied from 0.07 percent - 2.04 percent. The abundance of high molecular weight n-alkanes (n-C27 and greater) suggests that terrestrial organic matter was present in nearly all samples. Terrestrial organic matter input to the basin was characterized using a crossplot of pristane/n-C17 versus phytane/n-C18. Ramp siltstones showed ~10-fold greater variation in terrestrial content than did turbiditic sandstones and siltstones. This observation is more consistent with the aeolo-marine interpretation of ramp siltstones, and suggests that terrestrial organic matter was delivered to the Delaware Basin by wind transport during deposition of the Brushy Canyon Formation.

Early Channel Evolution in the Middle Permian Brushy Canyon Formation, West Texas, USA  

E-Print Network (OSTI)

Submarine channels are important conduits for sediment in deep marine environments, and understanding their formation is critical to modeling basin fill processes. Most models describing channel evolution focus on turbidity currents as the erosive and constructive force in channel initiation. However, slope failure and slumping can be significant drivers of channelization, particularly in upper slope and ramp environments. Determining the relative roles of slumping and erosion by turbidity currents can provide important insight into the timing of channelization and the geometries of subsequent deposits. Samples were collected from Guadalupe Mountains National Park from two primary localities at Salt Flat Bench (Figure 2). Three vertical sections were measured at both locations. A total of 16 samples were collected for petrographic analysis and X-ray fluorescence (XRF) imaging. Spectacular outcrop quality makes the Middle Permian Brushy Canyon Formation in Guadalupe Mountains National Park an ideal location for the study of early channel evolution. A detailed facies analysis of fine-grained channel deposits was conducted in the Upper Brushy Canyon Formation in the Salt Flat Bench outcrops. After channelization, an interval of relative condensation dominated by hemipelagic settling of organic matter and silt was followed by an interval of incomplete sediment bypass by turbidity currents. This sequence of events suggests that sea level was at a relative highstand at the time of channel inception, whereas channel inception by turbidity currents is expected during a lowstand. Slumping rather than erosion by turbidity currents is the most likely mechanism to have initiated a channel at the study area. There is no evidence for the existence for high energy currents until after the interval of condensation. However, the action of weak contour currents during early channel evolution is observed in outcrop and microtextural features. Early carbonate cementation of channel-lining silts may have stabilized the slump surface with respect to erosion by later turbidity currents.

Application of USNRC NUREG/CR-6661 and draft DG-1108 to evolutionary and advanced reactor designs  

Science Conference Proceedings (OSTI)

For the seismic design of evolutionary and advanced nuclear reactor power plants, there are definite financial advantages in the application of USNRC NUREG/CR-6661 and draft Regulatory Guide DG-1108. NUREG/CR-6661, 'Benchmark Program for the Evaluation of Methods to Analyze Non-Classically Damped Coupled Systems', was by Brookhaven National Laboratory (BNL) for the USNRC, and Draft Regulatory Guide DG-1108 is the proposed revision to the current Regulatory Guide (RG) 1.92, Revision 1, 'Combining Modal Responses and Spatial Components in Seismic Response Analysis'. The draft Regulatory Guide DG-1108 is available at http://members.cox.net/apolloconsulting, which also provides a link to the USNRC ADAMS site to search for NUREG/CR-6661 in text file or image file. The draft Regulatory Guide DG-1108 removes unnecessary conservatism in the modal combinations for closely spaced modes in seismic response spectrum analysis. Its application will be very helpful in coupled seismic analysis for structures and heavy equipment to reduce seismic responses and in piping system seismic design. In the NUREG/CR-6661 benchmark program, which investigated coupled seismic analysis of structures and equipment or piping systems with different damping values, three of the four participants applied the complex mode solution method to handle different damping values for structures, equipment, and piping systems. The fourth participant applied the classical normal mode method with equivalent weighted damping values to handle differences in structural, equipment, and piping system damping values. Coupled analysis will reduce the equipment responses when equipment, or piping system and structure are in or close to resonance. However, this reduction in responses occurs only if the realistic DG-1108 modal response combination method is applied, because closely spaced modes will be produced when structure and equipment or piping systems are in or close to resonance. Otherwise, the conservatism in the current Regulatory Guide 1.92, Revision 1, will overshadow the advantage of coupled analysis. All four participants applied the realistic modal combination method of DG-1108. Consequently, more realistic and reduced responses were obtained. (authors)

Very heavily electron-doped CrSi2 as a high performance high temperature thermoelectric material  

SciTech Connect

We analyze the thermoelectric behavior, using first principles and Boltzmann transport calculations, of very heavily electron-doped CrSi2 and find that at temperatures of 1250 K and electron dopings of $1-4 \\times10^{21}$ cm$^{-3}$, thermopowers as large or larger in magnitude than 200 $\\mathrm{\\mu}$V/K may be found. Such high thermopowers at such high carrier concentrations are extremely rare, and suggest that good thermolectric performance (i.e. ZT) may be found in these ranges of temperature and doping.

Influence of intergranular exchange coupling on the magnetization dynamics of CoCrPt:SiO{sub 2} granular media  

Science Conference Proceedings (OSTI)

We investigate the effect of Co{sup +} irradiation on the magnetization dynamics of CoCrPt:SiO{sub 2} granular media. Increasing irradiation levels reduce the saturation magnetization and effective anisotropy, which decrease the intrinsic magnetization precession frequency. Furthermore, increasing intergranular exchange coupling results in a qualitative change in the behavior of the magnetic material from a collection of individual grains to a homogeneous thin film, as evidenced in both the switching behavior and dynamics. The frequency change cannot be explained by single crystal macrospin modeling, and can only be reproduced by the inclusion of the dipolar effects and anisotropy distribution inherent in a granular medium.

Bull Trout Population and Habitat Surveys in the Middle Fork Willamette and McKenzie Rivers, Annual Report 2002.  

DOE Green Energy (OSTI)

Bull trout in the Willamette River Basin were historically distributed throughout major tributaries including the Middle Fork Willamette and McKenzie rivers. Habitat degradation, over-harvest, passage barriers, fish removal by rotenone, and hybridization and competition with non-native brook trout are all likely factors that have led to the decline of bull trout in the Willamette Basin (Ratliff and Howell 1992). The U.S. Fish and Wildlife Service listed the Columbia River bull trout population segment as Threatened under the federal Endangered Species Act in 1998. Four bull trout populations were isolated in the upper Willamette River following the construction of flood control dams on the South Fork McKenzie River, McKenzie River, and Middle Fork Willamette River that created Cougar, Trail Bridge, and Hills Creek reservoirs. Buchanan et al. (1997) described the population in the main stem McKenzie as 'of special concern', the South Fork McKenzie population as 'high risk of extinction', the population above Trail Bridge Reservoir as 'high risk of extinction', and bull trout in the Middle Fork Willamette as 'probably extinct'. Various management efforts such as strict angling regulations and passage improvement projects have been implemented to stabilize and rehabilitate bull trout habitat and populations in the McKenzie River over the past 10 years. Since 1997, bull trout fry from Anderson Creek on the upper McKenzie River have been transferred to the Middle Fork Willamette basin above Hills Creek Reservoir in an attempt to re-establish a reproducing bull trout population. This project was developed in response to concerns over the population status and management of bull trout in the McKenzie and Middle Fork Willamette Rivers by the Oregon Department of Fish and Wildlife during the early 1990s. The project was conducted under measure 9.3G(2) of the Columbia Basin Fish and Wildlife Program to monitor the status, life history, habitat needs, and limiting factors for bull trout within sub basins of the Columbia River. Also, this project provides information to develop native fish recovery plans such as the Oregon Plan for Salmon and Watersheds and the U.S. Fish and Wildlife Bull Trout Recovery Plan.
