Trending: Metal Oxo Bonds Trending: Metal Oxo Bonds Trending: Metal Oxo Bonds Print Wednesday, 29 May 2013 00:00 Metal oxides are important for scientific and technical applications in a variety of disciplines, including materials science, chemistry, and biology. Highly covalent metal-oxygen multiple bonds (metal oxos) are the building blocks of metal oxides and have a bearing on the oxide's desirable chemical, magnetic, electronic, and thermal properties. The lack of a more sophisticated grasp of bonding in metal oxides constitutes a roadblock to innovation in a wide variety of important emergent technologies, including industrial catalysis, biomimetic transformations, and artificial photosynthesis. To address this problem, a research team from four national laboratories, three Department of Energy synchrotron user facilities, and the University of Washington has applied spectroscopic and computational analyses to a number of metal oxides, quantifying trends in metal oxo bonding for groups of metals across the periodic table.

Seasonal trends in growth and biomass accumulation of selected nutrients and metals in six species of emergent aquatic macrophytes  

SciTech Connect (OSTI)

Growth and biomass accumulation of selected nutrients and trace metals were monitored for six species of aquatic macrophytes during June, August and November, 1993. Plant species were cultivated in two polyculture treatments, each replicated three times. Polyculture I consisted of Scirpus acutus (hardstem bullrush), Phragmites communes (common reed), and Phalaris arundinacea (canary grass). Polyculture H consisted of Typha spp. (cattail), Scirpus atrovirens (green bullrush), and Scirpus cyperinus (wool grass). Each of the six cells (6 x 9 x 0.6 m), was operated as a gravel-substrate, subsurface-flow wetlands in a continuous recirculating mode. At six week intervals, macro, micro and trace elements were dissolved and added to the sump of the recirculating system. On each of three sampling dates, replicate shoot and root samples were collected, segregated by species and tissue type (roots, rhizomes, stems and leaves), and prepared for gravimetric biomass estimates and chemical analysis. Tissue specific concentrations of N, P, K, Ca, Mg, Fe, Mn, Zn and Cu, were determined on each date for each species and tissue type. Results will be discussed with respect to species specific growth rates, biomass accumulation, and seasonal uptake and translocation of plant nutrients.

Chemical conversions of butyraldehydes during separation of the products of oxo synthesis  

SciTech Connect (OSTI)

It was shown that aldol condensation and formation of acetals occur during isolation of butyraldehydes by continuous fractionation of the products of oxo synthesis. Aldehyde losses due to chemical conversions decrease with increase of temperature in the reboiler, and may be virtually eliminated, while the selectivity of formation of the products of aldol condensation increases.

Condensation temperature trends among stars with planets  

E-Print Network [OSTI]

Results from detailed spectroscopic analyses of stars hosting massive planets are employed to search for trends between abundances and condensation temperatures. The elements C, S, Na, Mg, Al, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni and Zn are included in the analysis of 64 stars with planets and 33 comparison stars. No significant trends are evident in the data. This null result suggests that accretion of rocky material onto the photospheres of stars with planets is not the primary explanation for their high metallicities. However, the differences between the solar photospheric and meteoritic abundances do display a weak but significant trend with condensation temperature. This suggests that the metallicity of the sun's envelope has been enriched relative to its interior by about 0.07 dex.

Downdip Yegua trend - overview  

SciTech Connect (OSTI)

The Downdip Yegua Trend of overpressured gas-condensate reservoirs has produced over 400 bcf of gas and 10 million bbl of oil and condensate since 1979. The trend has indicated reserves in the range of 1.5-2.0 tcf. The trend was opened only in the late 1970s and 1980s because its sandstone fairways are mostly separated from the updip, sandstone-rich Yegua section (which has produced since the 1930s) by a mid-dip region where sandstones are scarce. The trend is also separated from overlying Frio and Vicksburg targets by over 1,000 ft of highly overpressured Jackson shale. At present, activity is most concentrated on detecting sweet spots of a few hundred acres or less, evaluating downdip and lateral extensions of known trends, and in defining large, potentially prolific structures in frontier areas using integrated geologic and geophysical analyses.

Trends in properties of motor gasolines for the years 1942 through 1984; diesel fuels for the years 1950 through 1983; aviation fuels for the years 1947 through 1983; and heating oils for the years 1955 through 1984, have been evaluated based upon data contained in surveys prepared and published by the National Institute for Petroleum and Energy Research (NIPER) formerly the Bartlesville Energy Technology Center (BETC). The surveys for motor gasolines were conducted under a cooperative agreement with the Coordinating Research Council (CRC) and the Bureau of Mines from 1935 through 1948 and in cooperation with the American Petroleum Institute (API) since 1948 for all surveys. The motor gasoline surveys have been published twice annually since 1935 describing the properties of motor gasolines throughout the country. Other surveys prepared in cooperation with API and the Bureau of Mines, the Energy Research and Development Administration, the Department of Energy, and currently NIPER were aviation gasolines beginning in 1947, diesel fuels in 1950, aviation turbine fuels in 1951, and heating oils, formerly burner fuel oils, in 1955. Various companies throughout the country obtain samples of motor gasolines from retail outlets and refinery samples for the other surveys, and analyze the samples using American Society for Testing and Materials (ASTM) procedures. The analytical data are sent to the Bartlesville Center for survey preparation and distribution. A summary report has been assembled from data in 83 semiannual surveys for motor gasolines that shows trends throughout the entire era from winter 19

Carbon?Oxygen Bond Forming Mechanisms in Rhenium Oxo-Alkyl Complexes  

SciTech Connect (OSTI)

Three C?X bond formation mechanisms observed in the oxidation of (HBpz{sub 3})ReO(R)(OTf) [HBpz{sub 3} = hydrotris(1-pyrazolyl)borate; R = Me, Et, and iPr; OTf = OSO{sub 2}CF{sub 3}] by dimethyl sulfoxide (DMSO) were investigated using quantum mechanics (M06//B3LYP DFT) combined with solvation (using the PBF Poisson?Boltzmann polarizable continuum solvent model). For R = Et we find the alkyl group is activated through ?-hydrogen abstraction by external base OTf{sup ?} with a free energy barrier of only 12.0 kcal/mol, leading to formation of acetaldehyde. Alternatively, ethyl migration across the M?O bond (leading to the formation of acetaldehyde and ethanol) poses a free energy barrier of 22.1 kcal/mol, and the previously proposed ?-hydrogen transfer to oxo (a 2+2 forbidden reaction) poses a barrier of 44.9 kcal/mol. The rate-determining step to formation of the final product acetaldehyde is an oxygen atom transfer from DMSO to the ethylidene, with a free energy barrier of 15.3 kcal/mol. When R = iPr, the alkyl 1,2-migration pathway becomes the more favorable pathway (both kinetically and thermodynamically), with a free energy barrier (?G{sup ?} = 11.8 kcal/mol) lower than ?-hydrogen abstraction by OTf{sup ?} (?G{sup ?} = 13.5 kcal/mol). This suggests the feasibility of utilizing this type of migration to functionalize M?R to M?OR. We also considered the nucleophilic attack of water and ammonia on the Re-ethylidene ?-carbon as a means of recovering two-electron-oxidized products from an alkane oxidation. Nucleophilic attack (with internal deprotonation of the nucleophile) is exothermic. However, the subsequent protonolysis of the Re?alkyl bond (to liberate an alcohol or amine) poses a barrier of 37.0 or 42.4 kcal/mol, respectively. Where comparisons are possible, calculated free energies agree very well with experimental measurements.

Theory of bonding of transition metals to nontransition metals  

Science Journals Connector (OSTI)

We present a theory of the chemical bond in compounds consisting of both transition metals and nontransition metals. Chemical trends in the bonding properties are established by directly comparing the total energies of a large number of such compounds with the total energies of their constituents. These chemical trends are analyzed in terms of the s-, p-, and d-like state densities of the compounds and the constituents. Rather different types of bonding are shown to result when the atomic s and p levels of the nontransition metal lie above, below, and near the energy of the transition-metal d level. The heat of compound formation is shown to result from a competition between two simple physical effects: (1) the weakening of the transition-metal bonds by the lattice dilatation required for the accommodation of the nontransition metal, and (2) the increased bonding which results from the occupation of the bonding members of the hybrid states formed from the interaction between the transition-metal d states and the s-p states on the nontransition metal. Our theoretical values for the heats of formation of these compounds are generally similar to those given by Miedema's empirical formula. Distinctive aspects of the variation of the heat of formation with the number of valence electrons reveal, however, that the microscopic picture on which the empirical formula is based is quite different from that given by our self-consistent energy-band theory.

Ternary rare earth and actinoid transition metal carbides viewed as carbometalates  

SciTech Connect (OSTI)

Ternary carbides A{sub x}T{sub y}C{sub z} (A=rare earth metals and actinoids; T=transition metals) with monoatomic species C{sup 4-} as structural entities are classified according to the criteria (i) metal to carbon ratio, (ii) coordination number of the transition metal by carbon atoms, and (iii) the dimensionality of the anionic network [T{sub y}C{sub z}]{sup n-}. Two groups are clearly distinguishable, depending on the metal to carbon ratio. Those where this ratio is equal to or smaller than 2 may be viewed as carbometalates, thus extending the sequence of complex anions from fluoro-, oxo-, and nitridometalates to carbometalates. The second group, metal-rich carbides with metal to carbon ratios equal to or larger than 4 is better viewed as typical intermetallics (''interstitial carbides''). The chemical bonding properties have been investigated by analyzing the Crystal Orbital Hamilton Population (COHP). The chemical bonding situation with respect to individual T-C bonds is similar in both classes. The main difference is the larger number of metal-metal bonds in the crystal structures of the metal-rich carbides.

Ptmetal oxide aerogel catalysts: X-ray photoemission investigation  

Science Journals Connector (OSTI)

X-ray photoemission spectroscopy was used to study Ptmetal oxide aerogel catalysts that have been developed to respond to increased NO x emissions of lean-burn engines. Lean-burn engines critical components of low and zero emission vehicles produce much higher levels of engine-out NO x and current three-way catalytic converters are not sufficient to meet Clean Air Act standards. Platinum catalysts were formed by the reaction of modified Pt coordination compounds with selected transitionmetal alkoxides through solgel techniques into aerogels. Photoemission measurements of the Pt 4f Si 2p Ti 2p O 1s and C 1s core lines were used to evaluate the chemistry of the material after each processing step. Results indicate PtO bonding and reduced Pt disbursed in the aerogel. In addition Si 2p Ti 2p and O 1s binding energies indicate an oxo-bridged network structure.

Nuclear Proliferation Technology Trends Analysis  

SciTech Connect (OSTI)

A process is underway to develop mature, integrated methodologies to address nonproliferation issues. A variety of methodologies (both qualitative and quantitative) are being considered. All have one thing in common, a need for a consistent set of proliferation related data that can be used as a basis for application. One approach to providing a basis for predicting and evaluating future proliferation events is to understand past proliferation events, that is, the different paths that have actually been taken to acquire or attempt to acquire special nuclear material. In order to provide this information, this report describing previous material acquisition activities (obtained from open source material) has been prepared. This report describes how, based on an evaluation of historical trends in nuclear technology development, conclusions can be reached concerning: (1) The length of time it takes to acquire a technology; (2) The length of time it takes for production of special nuclear material to begin; and (3) The type of approaches taken for acquiring the technology. In addition to examining time constants, the report is intended to provide information that could be used to support the use of the different non-proliferation analysis methodologies. Accordingly, each section includes: (1) Technology description; (2) Technology origin; (3) Basic theory; (4) Important components/materials; (5) Technology development; (6) Technological difficulties involved in use; (7) Changes/improvements in technology; (8) Countries that have used/attempted to use the technology; (9) Technology Information; (10) Acquisition approaches; (11) Time constants for technology development; and (12) Required Concurrent Technologies.

General trend for pressurized superconducting hydrogen-dense materials  

SciTech Connect (OSTI)

The long-standing prediction that hydrogen can assume a metallic state under high pressure, combined with arguments put forward more recently that this state might even be superconducting up to high temperatures, continues to spur tremendous research activities toward the experimental realization of metallic hydrogen. These efforts have however so far been impeded by the enormous challenges associated with the exceedingly large required pressure. Hydrogen-dense materials, of the MH{sub 4} form (where M can be, e.g., Si, Ge, or Sn) or of the MH{sub 3} form (with M being, e.g., Al, Sc, Y, or La), allow for the rather exciting opportunity to carry out a proxy study of metallic hydrogen and associated high-temperature superconductivity at pressures within the reach of current techniques. At least one experimental report indicates that a superconducting state might have been observed already in SiH{sub 4}, and several theoretical studies have predicted superconductivity in pressurized hydrogen-rich materials; however, no systematic dependence on the applied pressure has yet been identified so far. In the present work, we have used first-principles methods in an attempt to predict the superconducting critical temperature (T{sub c}) as a function of pressure (P) for three metal-hydride systems of the MH{sub 3} form, namely ScH{sub 3}, YH{sub 3}, and LaH{sub 3}. By comparing the obtained results, we are able to point out a general trend in the T{sub c}-dependence on P. These gained insights presented here are likely to stimulate further theoretical studies of metallic phases of hydrogen-dense materials and should lead to new experimental investigations of their superconducting properties.

Preparative enzymatic solid phase synthesis of cis(+)-12-oxo-phytodienoic acid physical interaction of AOS and AOC is not necessary  

Science Journals Connector (OSTI)

The pathway of jasmonic acid (JA) biosynthesis was established in the 1980s by Vick and Zimmerman but, until now, the preparative biosynthesis of the jasmonic acid precursors 12-oxo-phytodienoic acid (OPDA) and 3-oxo-2-[2?-pentenyl]-cyclopentan-1-octanoic acid (OPC-8:0) in their endogenous and biologically relevant cis(+)-configuration was only possible in small amounts and had to put up with high costs. This was mainly due to the lack of high amounts of pure and enzymatically active allene oxide cyclase (AOC), which is a key enzyme in the biosynthesis of jasmonates in that it releases, in a coupled reaction with allene oxide synthase (AOS), the first cyclic and biological active metabolite OPDA. We describe here the expression and purification of AOS and AOC and their subsequent coupling to solid matrices to produce an enantioselective, reusable bioreactor for octadecanoid production. With the method described here it is possible to produce optically pure enantiomers of octadecanoids in high amounts in a cost- and time-efficient manner. Furthermore, it could be demonstrated that a physical interaction of AOS and AOC, hitherto postulated to be required for substrate channeling from AOS to AOC, is not necessary for the in vitro cyclization of the unstable epoxide generated by the AOS reaction.

Damped trend exponential smoothing: A modelling viewpoint  

Science Journals Connector (OSTI)

Over the past twenty years, damped trend exponential smoothing has performed well in numerous empirical studies, and it is now well established as an accurate forecasting method. The original motivation for this method was intuitively appealing, but said very little about why or when it provided an optimal approach. The aim of this paper is to provide a theoretical rationale for the damped trend method based on Browns original thinking about the form of underlying models for exponential smoothing. We develop a random coefficient state space model for which damped trend smoothing provides an optimal approach, and within which the damping parameter can be interpreted directly as a measure of the persistence of the linear trend.

EMERGING TRENDS IN A PERIOD-RADIUS DISTRIBUTION OF CLOSE-IN PLANETS  

SciTech Connect (OSTI)

We analyze the distribution of extrasolar planets (both confirmed and Kepler candidates) according to their orbital periods P and planetary radii R. Among confirmed planets, we find compelling evidence for a paucity of bodies with 3 R {sub Circled-Plus} < R < 10 R {sub Circled-Plus }, where R {sub Circled-Plus} is Earth's radius and P < 2-3 days. We have christened this region a sub-Jovian Pampas. The same trend is detected in multiplanet Kepler candidates. Although approximately 16 Kepler single-planet candidates inhabit this Pampas, at least 7 are probable false positives (FPs). This last number could be significantly higher if the ratio of FPs is higher than 10%, as suggested by recent studies. In a second part of the paper we analyze the distribution of planets in the (P, R) plane according to stellar metallicities. We find two interesting trends: (1) a lack of small planets (R < 4 R {sub Circled-Plus }) with orbital periods P < 5 days in metal-poor stars and (2) a paucity of sub-Jovian planets (4 R {sub Circled-Plus} < R < 8 R {sub Circled-Plus }) with P < 100 days, also around metal-poor stars. Although all these trends are preliminary, they appear statistically significant and deserve further scrutiny. If confirmed, they could represent important constraints on theories of planetary formation and dynamical evolution.

Multiplicative trend exponential smoothing has received very little attention in the literature. It involves modelling the local slope by smoothing successive ratios of the local level, and this leads to a forecast function that is the product of level and growth rate. By contrast, the popular Holt method uses an additive trend formulation. It has been argued that more real series have multiplicative trends than additive. However, even if this is true, it seems likely that the more conservative forecast function of the Holt method will be more robust when applied in an automated way to a large batch of series with different types of trend. In view of the improvements in accuracy seen in dampening the Holt method, in this paper we investigate a new damped multiplicative trend approach. An empirical study, using the monthly time series from the M3-Competition, gave encouraging results for the new approach at a range of forecast horizons, when compared to the established exponential smoothing methods.

Trends and balances: 1985-1990  

SciTech Connect (OSTI)

This is the seventh edition of Trends and Balances to be presented to the staff of Oak Ridge National (ORNL) and other interested parties. Each year at the end of the planning cycle the Laboratory publishes its official planning document, the Institutional Plan. Trends and Balances is brought out as a condensation of that more formal document and is intended to provide a reference to the kinds of plans that have occupied senior laboratory management over the past year. An institution as large as ORNL changes slowly, so some of the information in this document overlaps that contained in the previous edition of Trends and Balances. Much, however, is different. A new section, for example, describes what senior Laboratory management feels are five new directions for science and technology at ORNL. This document is intended to provide new insights into the programs and structure of the Laboratory.

Persistent collective trend in stock markets  

Science Journals Connector (OSTI)

Empirical evidence is given for a significant difference in the collective trend of the share prices during the stock index rising and falling periods. Data on the Dow Jones Industrial Average and its stock components are studied between 1991 and 2008. Pearson-type correlations are computed between the stocks and averaged over stock pairs and time. The results indicate a general trend: whenever the stock index is falling the stock prices are changing in a more correlated manner than in case the stock index is ascending. A thorough statistical analysis of the data shows that the observed difference is significant, suggesting a constant fear factor among stockholders.

Ferromagnetism and antiferromagnetism of 3d-metal overlayers on metals  

Science Journals Connector (OSTI)

We report systematic calculations based on the full-potential linearized augmented-plane-wave method for the whole transition-metal series (V,Cr,Mn,Fe,Co,Ni) as overlayers on the Pd(001) surface. An energy analysis shows that Fe, Co, and Ni overlayers favor the ferromagnetic p(11) configuration, but V, Cr, and Mn, the antiferromagnetic c(22) superstructure. We conjecture that this result is a general trend which should also be found on the (001) surfaces of Pt and the noble metals.

Identifying recent trends in nanomedicine development  

Science Journals Connector (OSTI)

Medical nanotechnology is a recent emerging field with the intention to improve human health. The creation and rapid expansion of nanomedicine as a new research field in the last decade is the result of nanotechnology's convergence with biology, genetics, biochemistry, chemistry, physics, pharmacology and medicine. Within nanomedicine, two major categories have emerged: diagnostics (imaging) and therapeutics (drug delivery). Each of these branches has several nanoparticle types that are actively under research and development. While nanomedicine research and use of various nanoparticles in new applications have been categorised and reviewed for their potential utility in medicine, there has been little context of the emerging trends within nanomedicine or how the field is progressing. This article presents an overview of the trends for nanomedicine that are developing over time as measured by examining peer review research literature and patent databases.

Retrospective Evaluation of Appliance Price Trends  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Evaluation of Appliance Price Trends Evaluation of Appliance Price Trends Title Retrospective Evaluation of Appliance Price Trends Publication Type Journal Article Year of Publication 2009 Authors Dale, Larry L., Camille Antinori, Michael A. McNeil, James E. McMahon, and Sydny K. Fujita Journal Energy Policy Volume 37 Issue 2 Pagination 597-605 Date Published November 20 Keywords appliance efficiency standards, price forecasts, EES-EG Abstract Real prices of major appliances (refrigerators, dishwashers, heating and cooling equipment) have been falling since the late 1970s despite increases in appliance efficiency and other quality variables. This paper demonstrates that historic increases in efficiency over time, including those resulting from minimum efficiency standards, incur smaller price increases than were expected by the Department of Energy (DOE) forecasts made in conjunction with standards. This effect can be explained by technological innovation, which lowers the cost of efficiency, and by market changes contributing to lower markups and economies of scale in production of higher efficiency units. We reach four principal conclusions about appliance trends and retail price setting:1. For the past several decades, the retail price of appliances has been steadily falling while efficiency has been increasing.2. Past retail price predictions made by the DOE analyses of efficiency standards, assuming constant prices over time, have tended to overestimate retail prices.3. The average incremental price to increase appliance efficiency has declined over time. DOE technical support documents have typically overestimated this incremental price and retail prices.4. Changes in retail markups and economies of scale in production of more efficient appliances may have contributed to declines in prices of efficient appliances.

The US transportation sector, which remains 97% dependent on petroleum, used a record 22.8 quads of energy in 1993. Though growing much more slowly than the economy from 1975 to 1985, energy use for transportation is now growing at nearly the same rate as GDP. This report describes the analysis of trends in energy use and energy intensity in transportation into components due to, (1) growth in transportation activity, (2) changes in energy intensity, and (3) changes in the modal structure of transportation activities.

Development and trends in HVOF spraying technology  

Science Journals Connector (OSTI)

Three actual trends in development of HVOF spraying technology are described and discussed. The trends concern application fields as well as gun and feedstock characteristics. At the example of demountable draw bars it is shown that HVOF sprayed cermet coatings are capable to protect light weight material components subject to dynamical load against wear without detraction of fatigue strength. Personnel and production time savings can be exploited. High deposition efficiency at considerable powder feed rate, high density and negligible oxygen content in corrosion protective iron or nickel based coatings is achieved for spraying with newly developed HVOF guns operating at increased combustion chamber pressures. Also spraying of highly reactive materials like titanium under atmospheric conditions becomes feasible. A major obstacle for industrial use of respective coatings is the lack of adapted characterisation methods that permit to ascertain corrosion protective function. Ultrafine powder feedstock is used in order to reduce overall costs of wear protective cermet coatings due to the possibility to finish coatings by comparatively cheap belt grinding. However, it is shown that the replacement of coatings produced with conventional powder size fractions requires careful consideration of the particular tribological system. While cermet coatings produced with ultrafine powders outperform conventional coatings for sliding wear conditions, their capability to withstand dry abrasive wear stress is poor. The benefits concerning coating production costs may be outweighed by significantly decreased component life time.

Volatile Species Retention During Metallic Fuel Casting  

SciTech Connect (OSTI)

Metallic nuclear fuels are candidate transmutation fuel forms for advanced fuel cycles. Through the operation of the Experimental Breeder Reactor II metallic nuclear fuels have been shown to be robust and easily manufactured. However, concerns have been raised concerning loss of americium during the casting process because of its high vapor pressure. In order to address these concerns a gaseous diffusion model was developed and a series of experiments using both manganese and samarium as surrogates for americium were conducted. The modeling results showed that volatility losses can be controlled to essentially no losses with a modest overpressure. Experimental results also showed volatile species retention down to no detectable losses through overpressure, although the loss values varied from the model results the same trend was seen. Bases on these results it is very probably that americium losses through volatility can be controlled to no detectable losses through application of a modest overpressure during casting.

Pulsed laser irradiation of metal multilayers.  

SciTech Connect (OSTI)

Vapor-deposited, exothermic metal-metal multilayer foils are an ideal class of materials for detailed investigations of pulsed laser-ignited chemical reactions. Created in a pristine vacuum environment by sputter deposition, these high purity materials have well-defined reactant layer thicknesses between 1 and 1000 nm, minimal void density and intimate contact between layers. Provided that layer thicknesses are made small, some reactive metal-metal multilayer foils can be ignited at a point by laser irradiation and exhibit subsequent high-temperature, self-propagating synthesis. With this presentation, we describe the pulsed laser-induced ignition characteristics of a single multilayer system (equiatomic Al/Pt) that exhibits self-propagating synthesis. We show that the thresholds for ignition are dependent on (i) multilayer design and (ii) laser pulse duration. With regard to multilayer design effects on ignition, there is a large range of multilayer periodicity over which ignition threshold decreases as layer thicknesses are made small. We attribute this trend of decreased ignition threshold to reduced mass transport diffusion lengths required for rapid exothermic mixing. With regard to pulse duration effects, we have determined how ignition threshold of a single Al/Pt multilayer varies with pulse duration from 10{sup -2} to {approx} 10{sup -13} sec (wavelength and spot size are held constant). A higher laser fluence is required for ignition when using a single laser pulse {approx} 100 fs or 1 ps compared with nanosecond or microsecond exposure, and we attribute this, in part, to the effects of reactive material being ablated when using the shorter pulse durations. To further understand these trends and other pulsed laser-based processes, our discussion concludes with an analysis of the heat-affected depths in multilayers as a function of pulse duration.

Reactivity studies of a pseudo three-coordinate vanadium(II) complex: Synthesis of terminal oxo and sulfido complexes of vanadium(IV) and S?S and Se?Se reductive bond cleavage reactions  

SciTech Connect (OSTI)

Terminal oxo and sulfido complexes in the form of (nacnac)V=E(Ntol{sub 2}) (nacnac = [ArNC(CH{sub 3})]{sub 2}CH{sup -}, Ar = 2,6-(CHMe{sub 2}){sub 2}C{sub 6}H{sub 3}, Ntol{sub 2} = {sup -}N(C{sub 6}H{sub 4}-4-Me), E = O (1), S (2)) were isolated from treatment of the masked three-coordinate vanadium(II) complex, (nacnac)V(Ntol{sub 2}), with C{sub 5}H{sub 5}NO and S{sub 8}, respectively. Both vanadium(IV) species, 1 and 2, have been characterized by room temperature X-band EPR spectroscopic studies, and in the case of complex 1, a single crystal molecular structure confirmed the presence of a terminal oxo moiety. Moreover, reaction of (nacnac)V(Ntol{sub 2}) with diphenyl-disulfide and diphenyl-diselenide results in the reductive cleavage of these compounds to produce the vanadium(III) complexes (nacnac)V(XPh)(Ntol{sub 2}) (X = S, (3), Se (4)). A molecular structure of the phenylsulfide complex, 3, confirmed formation of the d{sup 2} complex resulting from reductive cleavage of the S-S bond.

Nanotechnology in water treatment: an emerging trend  

Science Journals Connector (OSTI)

With advances in nanotechnology, different types of nanomaterial are emerging for applications in water purification and water treatment devices owing to their effectiveness against both chemical and biological contaminants. This paper discusses the application of nanoscale materials that are being evaluated or developed as functional materials for water treatment, e.g. nanomembranes (nanocomposite RO and NF and carbon nanotubes), metal nanoparticles, nanoadsorbents, magnetic nanoparticles, bioactive nanoparticles, carbonaceous nanomaterials, zeolites, dendrimers and nanofibres. Nanomaterials are intrinsically better in terms of performance than other substances used in water treatment because of their high surface area (surface/volume ratio). Owing to these characteristics, these may be used in future at large scale for water purification.

Extraction process for removing metallic impurities from alkalide metals  

DOE Patents [OSTI]

A development is described for removing metallic impurities from alkali metals by employing an extraction process wherein the metallic impurities are extracted from a molten alkali metal into molten lithium metal due to the immiscibility of the alkali metals in lithium and the miscibility of the metallic contaminants or impurities in the lithium. The purified alkali metal may be readily separated from the contaminant-containing lithium metal by simple decanting due to the differences in densities and melting temperatures of the alkali metals as compared to lithium.

Photoactivated metal removal  

SciTech Connect (OSTI)

The authors propose the use of photochromic dyes as light activated switches to bind and release metal ions. This process, which can be driven by solar energy, can be used in environmental and industrial processes to remove metals from organic and aqueous solutions. Because the metals can be released from the ligands when irradiated with visible light, regeneration of the ligands and concentration of the metals may be easier than with conventional ion exchange resins. Thus, the process has the potential to be less expensive than currently used metal extraction techniques. In this paper, the authors report on their studies of the metal binding of spirogyran dyes and the hydrolytic stability of these dyes. They have prepared a number of spirogyrans and measured their binding constants for calcium and magnesium. They discuss the relationship of the structure of the dyes to their binding strengths. These studies are necessary towards determining the viability of this technique.

Performance trends for POD as measured in the ICON project  

SciTech Connect (OSTI)

Base line probability of detection (POD) data is often obtained under semi-ideal conditions such as laboratory diving trials. This performance may be affected by in-service complications such as deep water, corrosion, method of deployment, and also specimen material and geometry. The ICON project has included a wide range of test conditions allowing the development of performance trends to predict POD under non ideal conditions. Examples of these performance trends will be described in the paper.

U.S. Energy Information Administration (EIA) Indexed Site

Home > Trends in Commercial Buildings > Home > Trends in Commercial Buildings > Trends in Buildings Floorspace Data tables Commercial Buildings Trend—Detail Commercial Floorspace Trend—Detail Background: Adjustment to data Trends in Buildings and Floorspace Each year buildings are added to and removed from the commercial buildings sector. Buildings are added by new construction or conversion of existing buildings from noncommercial to commercial activity. Buildings are removed by demolition or conversion from commercial to noncommercial activity. Number of Commercial Buildings In 1979, the Nonresidential Buildings Energy Consumption Survey estimated that there were 3.8 million commercial buildings in the United States; by 1992, the number increased 27 percent to 4.8 million (an average annual increase of 1.8%) (Figure 1). In 1995, the estimated number declined to 4.6 million buildings, but it is unlikely that there was an actual decline in the number of buildings. To understand the apparent decline, two factors should be considered—the change in the way that the target population of commercial buildings was defined in 1995 and the uncertainty of estimates from sample surveys:

Silicon metal-semiconductor-metal photodetector  

DOE Patents [OSTI]

Silicon MSM photodiodes sensitive to radiation in the visible to near infrared spectral range are produced by altering the absorption characteristics of crystalline Si by ion implantation. The implantation produces a defected region below the surface of the silicon with the highest concentration of defects at its base which acts to reduce the contribution of charge carriers formed below the defected layer. The charge carriers generated by the radiation in the upper regions of the defected layer are very quickly collected between biased Schottky barrier electrodes which form a metal-semiconductor-metal structure for the photodiode.

Symmetry reduction of metal phthalocyanines on metals  

Science Journals Connector (OSTI)

The temperature-dependent adsorption behavior of fourfold symmetric metal phthalocyanines (MPcs) on metals with commensurate and incommensurate symmetries was investigated by scanning tunneling microscopy. On the fourfold symmetric Cu(100) surface, planar and fourfold molecular structures in two equivalent orientations were found for MPcs when prepared at room temperature. In addition, two metastable orientations were identified when prepared at low temperature, which can be depopulated upon annealing. MPcs adsorbed on the sixfold symmetric Cu(111) surface showed a disturbed molecular appearance. The symmetry of molecular structures changed from fourfold to twofold, which is discussed in terms of molecule-substrate interaction.

Models of the Solar Vicinity: The Metal Rich Stage  

E-Print Network [OSTI]

I present a review of chemical evolution models of the solar neighborhood. I give special attention to the necessary ingredients to reproduce the observed [Xi/Fe] ratios in nearby metal and super metal rich stars, and to the chemical properties of the solar vicinity focusing on [Fe/H] > -0.1. I suggest that the observed abundance trends are due to material synthesized and ejected by intermediate mass stars with solar metallicity in the AGB stage, and also by massive stars with (super) solar metallicity in the stellar wind and supernovae stages. The required tool to build chemical evolution models that reach super-solar metallicities is the computation of stellar yields for stellar metallicities higher than the initial solar value. Based on these models it might be possible to estimate the importance of merger events in the recent history of the Galactic disk as well as the relevance of radial stellar migration from the inner to the outer regions of the Galaxy. I also present a short review of the photospheric solar abundances and their relation with the initial solar abundances.

Liquid metal electric pump  

DOE Patents [OSTI]

An electrical pump for pumping liquid metals to high pressures in high temperature environments without the use of magnets or moving mechanical parts. The pump employs a non-porous solid electrolyte membrane, typically ceramic, specific to the liquid metal to be pumped. A DC voltage is applied across the thickness of the membrane causing ions to form and enter the membrane on the electrically positive surface, with the ions being neutralized on the opposite surface. This action provides pumping of the liquid metal from one side of the non-porous solid electrolyte membrane to the other. 3 figs.

PREFERRED WATERFLOOD MANAGEMENT PRACTICES FOR THE SPRABERRY TREND AREA  

SciTech Connect (OSTI)

The naturally fractured Spraberry Trend Area is one of the largest reservoirs in the domestic U.S. and is the largest reservoir in area extent in the world. Production from Spraberry sands is found over a 2,500 sq. mile area and Spraberry reservoirs can be found in an eight county area in west Texas. Over 150 operators produce 65,000 barrels of oil per day (bopd) from the Spraberry Trend Area from more than 9,000 production wells. Recovery is poor, on the order of 7-10% due to the profoundly complicated nature of the reservoir, yet billions of barrels of hydrocarbons remain. We estimate over 15% of remaining reserves in domestic Class III reservoirs are in Spraberry Trend Area reservoirs. This tremendous domestic asset is a prime example of an endangered hydrocarbon resource in need of immediate technological advancements before thousands of wells are permanently abandoned. This report describes the final work of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area.'' The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. This objective has been accomplished through research in three areas: (1) detail historical review and extensive reservoir characterization, (2) production data management, and (3) field demonstration. This provides results of the final year of the three-year project for each of the three areas.

SciTech Connect (OSTI)

Trends in motor gasolines between 1942 and 1981 have been evaluated based upon data contained in motor gasoline surveys that have been prepared and published by the Bartlesville Energy Technology Center (BETC). These surveys have been published twice annually since 1935 describing the properties of motor gasolines from throughout the country. They have been conducted in cooperation with the American Petroleum Institute since 1949. A typical report covers 2,400 samples from service stations throughout the country representing some 48 companies that manufacture and supply gasoline. The reports include trend charts, octane plots and properties obtained from a dozen different tests.

Ethylene from NGL feedstocks. Part 1-Trends favoring NGL feedstocks  

SciTech Connect (OSTI)

This paper addresses current trends that are making natural gas liquids (NGL) more attractive feedstocks for olefin plants than mid-distillates and heavier oils. Two of the trends examined involve motor gasoline production: that the volume consumed is decreasing and the percent of unleaded gasoline is increasing. This means that it will be difficult to blend light straight-run gasoline, natural gasoline and aromatics plant raffinate into the gasoline pool, due to the very low octane of each material. It is indicated, however, that they will make excellent feedstocks for ethylene plants.

Lithium metal reduction of plutonium oxide to produce plutonium metal  

DOE Patents [OSTI]

A method is described for the chemical reduction of plutonium oxides to plutonium metal by the use of pure lithium metal. Lithium metal is used to reduce plutonium oxide to alpha plutonium metal (alpha-Pu). The lithium oxide by-product is reclaimed by sublimation and converted to the chloride salt, and after electrolysis, is removed as lithium metal. Zinc may be used as a solvent metal to improve thermodynamics of the reduction reaction at lower temperatures. Lithium metal reduction enables plutonium oxide reduction without the production of huge quantities of CaO--CaCl.sub.2 residues normally produced in conventional direct oxide reduction processes.

EIA - AEO2010 - Energy intensity trends in AEO2010  

Gasoline and Diesel Fuel Update (EIA)

Trends in U.S. oil prices, energy consumption, and economic output, 1950-2035 Click to enlarge » Figure source and data excel logo Energy intensity trends in AEO2010 Energy intensity—energy consumption per dollar of real GDP—indicates how much energy a country uses to produce its goods and services. From the early 1950s to the early 1970s, U.S. total primary energy consumption and real GDP increased at nearly the same annual rate (Figure 17). During that period, real oil prices remained virtually flat. In contrast, from the mid-1970s to 2008, the relationship between energy consumption and real GDP growth changed, with primary energy consumption growing at less than one-third the previous average rate and real GDP growth continuing to grow at its historical rate. The decoupling of real GDP growth from energy consumption growth led to a decline in energy intensity that averaged 2.8 percent per year from 1973 to 2008. In the AEO2010 Reference case, energy intensity continues to decline, at an average annual rate of 1.9 percent from 2008 to 2035.

XPS study of Eu(III) coordination compounds: Core levels binding energies in solid mixed-oxo-compounds EumXxOy  

Science Journals Connector (OSTI)

Literature is relatively sparse on XPS studies of europium compounds: it is essentially restricted to metallic compounds (EuM5, in which M is a transition metal) or to simple oxides. While particular interest have been devoted to understanding physical phenomenon in the beginning of shake-down and shake-up satellites evidenced on core-level regions of the lanthanides, few information on absolute binding energies (BE) was available. This paper reports an XPS binding energy data base for europium(III) compounds, in which Eu cation have various chemical environments: simple oxide Eu2O3, Eu mixed oxides with organic oxalate, acetylacetonate or inorganic sulfate, nitrate, carbonate ligands. The values of core-level BE (O1s, Eu3d and Eu4d) and the characteristics of shake-down satellites of Eu3d are reported, and their variations are attributed to ionicity/covalency changes. Such interpretation was already published for Group A mixed oxides and zeolites. These data are needed for determining Eu(III) species sorbed onto minerals in the presence of various ligands in the framework of retention studies for assessing the safety of future nuclear waste disposals.

Transition-Metal Hydrides  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Transition-Metal Hydride Electrochromics Transition-Metal Hydride Electrochromics A new type of electrochromic hydride material has interesting and unusual properties. Thin Ni-Mg films, for example, are mirror-like in appearance and have very low visible transmittance. On exposure to hydrogen gas or on reduction in alkaline electrolyte, the films become transparent. The transition is believed to result from formation of nickel magnesium hydride, Mg2NiH4. Switchable mirrors based on rare earth hydrides were discovered in 1996 at Vrije University in the Netherlands, Rare earth-magnesium alloy films were subsequently found to be superior to the pure lanthanides in maximum transparency and mirror-state reflectivity by Philips Laboratories. The newer transition-metal types which use less expensive and less reactive materials were discovered at LBNL. This has now become a very active area of study with a network of researchers.

Metal alloy identifier  

DOE Patents [OSTI]

To identify the composition of a metal alloy, sparks generated from the alloy are optically observed and spectrographically analyzed. The spectrographic data, in the form of a full-spectrum plot of intensity versus wavelength, provide the "signature" of the metal alloy. This signature can be compared with similar plots for alloys of known composition to establish the unknown composition by a positive match with a known alloy. An alternative method is to form intensity ratios for pairs of predetermined wavelengths within the observed spectrum and to then compare the values of such ratios with similar values for known alloy compositions, thereby to positively identify the unknown alloy composition.

Petroleum 1996: Issues and Trends Petroleum 1996: Issues and Trends 49 The U.S. is heavily reliant on the world crude oil market, which has been subject to huge inter-annual volatility since 1973. Neither of these facts is likely to change. Domestic crude oil production declined over the past decade, while domestic crude oil demand increased. The difference was satisfied by increased crude oil imports. The United States' proved crude oil reserves declined more than 21 percent from 1985 to 1995. Its technically recoverable crude oil resources beyond proved reserves are estimated to be about 6 times more than the year-end 1995 proved reserves. However, excepting the Gulf of Mexico and the Alaskan offshore, many of the most promising oil-prone regions of the country are presently off-limits to exploration. Over the

Trends in On-Road Vehicle Emissions of Ammonia  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Trends in On-Road Vehicle Emissions of Ammonia Trends in On-Road Vehicle Emissions of Ammonia Title Trends in On-Road Vehicle Emissions of Ammonia Publication Type Journal Article Year of Publication 2008 Authors Kean, Andrew J., David Littlejohn, George Ban-Weiss, Robert A. Harley, Thomas W. Kirchstetter, and Melissa M. Lunden Journal Atmospheric Environment Abstract Motor vehicle emissions of ammonia have been measured at a California highway tunnel in the San Francisco Bay area. Between 1999 and 2006, light-duty vehicle ammonia emissions decreased by 38 ± 6%, from 640 ± 40 to 400 ± 20 mg kg-1. High time resolution measurements of ammonia made in summer 2001 at the same location indicate a minimum in ammonia emissions correlated with slower-speed driving conditions. Variations in ammonia emission rates track changes in carbon monoxide more closely than changes in nitrogen oxides, especially during later evening hours when traffic speeds are highest. Analysis of remote sensing data of Burgard et al. (Environ Sci. Technol. 2006, 40, 7018-7022) indicates relationships between ammonia and vehicle model year, nitrogen oxides, and carbon monoxide. Ammonia emission rates from diesel trucks were difficult to measure in the tunnel setting due to the large contribution to ammonia concentrations in a mixed-traffic bore that were assigned to light-duty vehicle emissions. Nevertheless, it is clear that heavy-duty diesel trucks are a minor source of ammonia emissions compared to light-duty gasoline vehicles.

Seasonality in the Natural Gas Balancing Item: Historical Trends and  

Gasoline and Diesel Fuel Update (EIA)

Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Released: June 4, 2010 Download Full Report (PDF) This special report examines an underlying cause of the seasonal pattern in the balancing item published in the Natural Gas Monthly. Research finds that a significant portion of data collected on EIA’s primary monthly natural gas consumption survey reflects billing data that does not strictly coincide with the actual calendar month, which creates an aggregate-level discrepancy with EIA’s other natural gas supply and disposition data series. This discrepancy is especially observable during the fall and spring as one transitions into and out of the winter heating season. The report also outlines improved data collection and estimation procedures that will be implemented later this year to more closely align reported and actual calendar month consumption. This discussion will be helpful to users of EIA’s volumetric natural gas data. Questions about this report should be directed to Andy Hoegh at andrew.hoegh@eia.doe.gov or (202) 586-9502.

Recent trends in automobile recycling: An energy and economic assessment  

SciTech Connect (OSTI)

Recent and anticipated trends in the material composition of domestic and imported automobiles and the increasing cost of landfilling the non-recyclable portion of automobiles (automobile shredder residue or ASR) pose questions about the future of automobile recycling. This report documents the findings of a study sponsored by the US Department of Energy`s Office of Environmental Analysis to examine the impacts of these and other relevant trends on the life-cycle energy consumption of automobiles and on the economic viability of the domestic automobile recycling industry. More specifically, the study (1) reviewed the status of the automobile recycling industry in the United States, including the current technologies used to process scrapped automobiles and the challenges facing the automobile recycling industry; (2) examined the current status and future trends of automobile recycling in Europe and Japan, with the objectives of identifying ``lessons learned`` and pinpointing differences between those areas and the United States; (3) developed estimates of the energy system impacts of the recycling status quo and projections of the probable energy impacts of alternative technical and institutional approaches to recycling; and (4) identified the key policy questions that will determine the future economic viability of automobile shredder facilities in the United States.

Science Journals Connector (OSTI)

A photoinduced magnetic moment has been observed in Cu and Al samples exposed to unpolarized visible light at low temperatures. It is shown that the light refected from a metal surface transfers some of its quasimomentum to conduction electrons. This mechanism creates surface currents which, for an appropriate geometry, bring about the photomagnetic effect.

Understanding Trends in Wind Turbine Prices Over the Past Decade

Understanding Trends in Wind Turbine Prices Over the Past Decade Understanding Trends in Wind Turbine Prices Over the Past Decade Title Understanding Trends in Wind Turbine Prices Over the Past Decade Publication Type Report Refereed Designation Unknown Year of Publication 2011 Authors Bolinger, Mark, and Ryan H. Wiser Pagination 46 Date Published 10/2011 Publisher LBNL City Berkeley Keywords electricity markets and policy group, energy analysis and environmental impacts department Abstract Berkeley Lab has gathered price data on 81 U.S. wind turbine transactions totaling 23,850 MW announced from 1997 through early 2011. Figure ES-1 depicts these reported wind turbine transaction prices (along with the associated trend line), broken out by the size of the transaction (in MW). Figure ES-1 also presents average (global) turbine prices reported by Vestas for the years 2005 through 2010, as well as a range of reported pricing (among various turbine manufacturers) for transactions signed in 2010 and so far in 2011 (with 2011 prices generally lower than 2010 prices). After hitting a low of roughly $750/kW from 2000 to 2002, average wind turbine prices doubled through 2008, rising to an average of roughly $1,500/kW. Wind turbine prices have since declined substantially, with price quotes for transactions executed in 2010 and to date in 2011 ranging from $900-$1,400/kW depending on the manufacturer and turbine model. For example, turbines designed for lower wind speed sites - deploying higher hub heights and larger rotor diameters for a given nameplate capacity - are priced at the higher end of this range. These quotes suggest price declines of as much as 33% or more since late 2008, with an average decline closer to perhaps 20% for orders announced in 2010 (as opposed to in 2011, which has seen further price declines). These two substantial and opposing wind turbine price trends over the past decade - and particularly the doubling in prices in the 2002-2008 period - run counter to the smooth, gradually declining technology cost trajectories that are often assumed by energy analysts modeling the diffusion of new technologies, including wind power. Understanding and explaining this notable discrepancy between theory and historical reality is the primary motivation for this work. Taking a bottom-up approach, this report examines seven primary drivers of wind turbine prices in the United States, with the goal of estimating the degree to which each contributed to the doubling in turbine prices from 2002 through 2008, as well as the subsequent decline in prices through 2010 (our analysis does not extend into 2011 because several of these drivers are best gauged on a full-year basis due to seasonality issues).

Purification of alkali metal nitrates  

DOE Patents [OSTI]

A process is disclosed for removing heavy metal contaminants from impure alkali metal nitrates containing them. The process comprises mixing the impure nitrates with sufficient water to form a concentrated aqueous solution of the impure nitrates, adjusting the pH of the resulting solution to within the range of between about 2 and about 7, adding sufficient reducing agent to react with heavy metal contaminants within said solution, adjusting the pH of the solution containing reducing agent to effect precipitation of heavy metal impurities and separating the solid impurities from the resulting purified aqueous solution of alkali metal nitrates. The resulting purified solution of alkali metal nitrates may be heated to evaporate water therefrom to produce purified molten alkali metal nitrate suitable for use as a heat transfer medium. If desired, the purified molten form may be granulated and cooled to form discrete solid particles of alkali metal nitrates.

Metal-Ion-Mediated Reactions Metal-Ion-Mediated Reactions Metal-Ion-Mediated Reactions Print Monday, 19 December 2011 18:29 While mononuclear, polynuclear, and polymeric metal complexes are most often synthesized by the reaction of a metal precursor and a presynthesized organic ligand, it is also possible to generate the ligand in situ from an easily available organic compound. This approach allows the reactivity of the metal ion to activate a proligand, transforming it through an in situ reaction, sometimes providing coordination compounds with ligands not accessible by conventional organic synthesis. The intense interest in the reactivity of coordinated ligands is mainly due to the necessity of interpreting the mechanisms of homogeneous metal-catalyzed processes, in which a substrate is activated upon its coordination to one or more metal sites. A coordinated oxime group contains three active sites (C, N, O) for reactivity.

Adsorption of propane, isopropyl, and hydrogen on cluster models of the M1 phase of Mo-V-Te-Nb-O mixed metal oxide catalyst  

SciTech Connect (OSTI)

The Mo-V-Te-Nb-O mixed metal oxide catalyst possessing the M1 phase structure is uniquely capable of directly converting propane into acrylonitrile. However, the mechanism of this complex eight-electron transformation, which includes a series of oxidative H-abstraction and N-insertion steps, remains poorly understood. We have conducted a density functional theory study of cluster models of the proposed active and selective site for propane ammoxidation, including the adsorption of propane, isopropyl (CH{sub 3}CHCH{sub 3}), and H which are involved in the first step of this transformation, that is, the methylene C-H bond scission in propane, on these active site models. Among the surface oxygen species, the telluryl oxo (Te=O) is found to be the most nucleophilic. Whereas the adsorption of propane is weak regardless of the MO{sub x} species involved, isopropyl and H adsorption exhibits strong preference in the order of Te=O > V=O > bridging oxygens > empty Mo apical site, suggesting the importance of TeO{sub x} species for H abstraction. The adsorption energies of isopropyl and H and consequently the reaction energy of the initial dehydrogenation of propane are strongly dependent on the number of ab planes included in the cluster, which points to the need to employ multilayer cluster models to correctly capture the energetics of surface chemistry on this mixed metal oxide catalyst.

SciTech Connect (OSTI)

We present initial results from a new high-contrast imaging program dedicated to stars that exhibit long-term Doppler radial velocity accelerations (or ''trends''). The goal of the TRENDS (TaRgetting bENchmark-objects with Doppler Spectroscopy) imaging survey is to directly detect and study the companions responsible for accelerating their host star. In this first paper of the series, we report the discovery of low-mass stellar companions orbiting HD 53665, HD 68017, and HD 71881 using NIRC2 adaptive optics (AO) observations at Keck. Follow-up imaging demonstrates association through common proper motion. These comoving companions have red colors with estimated spectral types of K7-M0, M5, and M3-M4, respectively. We determine a firm lower limit to their mass from Doppler and astrometric measurements. In the near future, it will be possible to construct three-dimensional orbits and calculate the dynamical mass of HD 68017 B and possibly HD 71881 B. We already detect astrometric orbital motion of HD 68017 B, which has a projected separation of 13.0 AU. Each companion is amenable to AO-assisted direct spectroscopy. Further, each companion orbits a solar-type star, making it possible to infer metallicity and age from the primary. Such benchmark objects are essential for testing theoretical models of cool dwarf atmospheres.

A CORRELATION BETWEEN THE ECLIPSE DEPTHS OF KEPLER GAS GIANT CANDIDATES AND THE METALLICITIES OF THEIR PARENT STARS  

SciTech Connect (OSTI)

Previous studies of the interior structure of transiting exoplanets have shown that the heavy-element content of gas giants increases with host star metallicity. Since metal-poor planets are less dense and have larger radii than metal-rich planets of the same mass, one might expect that metal-poor stars host a higher proportion of gas giants with large radii than metal-rich stars. Here I present evidence for a negative correlation at the 2.3{sigma} level between eclipse depth and stellar metallicity in the Kepler gas giant candidates. Based on Kendall's {tau} statistics, the probability that eclipse depth depends on star metallicity is 0.981. The correlation is consistent with planets orbiting low-metallicity stars being, on average, larger in comparison with their host stars than planets orbiting metal-rich stars. Furthermore, since metal-rich stars have smaller radii than metal-poor stars of the same mass and age, a uniform population of planets should show a rise in median eclipse depth with [M/H]. The fact that I find the opposite trend indicates that substantial changes in the gas giant interior structure must accompany increasing [M/H]. I investigate whether the known scarcity of giant planets orbiting low-mass stars could masquerade as an eclipse depth-metallicity correlation, given the degeneracy between metallicity and temperature for cool stars in the Kepler Input Catalog. While the eclipse depth-metallicity correlation is not yet on firm statistical footing and will require spectroscopic [Fe/H] measurements for validation, it is an intriguing window into how the interior structure of planets and even the planet formation mechanism may be changing with Galactic chemical evolution.

Hydrothermal alkali metal recovery process  

DOE Patents [OSTI]

In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein solid particles containing alkali metal residues are produced, alkali metal constituents are recovered from the particles by treating them with a calcium or magnesium-containing compound in the presence of water at a temperature between about 250.degree. F. and about 700.degree. F. and in the presence of an added base to establish a pH during the treatment step that is higher than would otherwise be possible without the addition of the base. During the treating process the relatively high pH facilitates the conversion of water-insoluble alkali metal compounds in the alkali metal residues into water-soluble alkali metal constituents. The resultant aqueous solution containing water-soluble alkali metal constituents is then separated from the residue solids, which consist of the treated particles and any insoluble materials formed during the treatment step, and recycled to the gasification process where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst. Preferably, the base that is added during the treatment step is an alkali metal hydroxide obtained by water washing the residue solids produced during the treatment step.

Water supply and sludge metals  

SciTech Connect (OSTI)

Ultimate sludge disposal is one of the major tasks facing wastewater treatment facilities today. Where adequate farmland exists in proximity to the treatment facility and where sludge characteristics are suitable, land application is often the most economical method. In some cases, however, metal concentrations in the sludge either limit the site life or the application rate to the point where land application is not economical. When metals are above regulatory limits, land application may become impossible. The origin of the metals has largely been credited to industrial users and stormwater runoff and have, in fact, often represented significant sources of metals. Another potentially significant source of metals that has been frequently overlooked is the water supply system (including the distribution and home piping systems). Data from some treatment facilities suggest that the water supply system is the major source of metals and is the reason that sewage sludge metal levels are above allowable land application limits.

PREFERRED WATERFLOOD MANAGEMENT PRACTICES FOR THE SPRABERRY TREND AREA  

SciTech Connect (OSTI)

This report describes the work performed during the second year of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area''. The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. To achieve this objective, in this period we concentrated our effort on characterization of Germania Unit using an analog field ET ODaniel unit and old cased hole neutron. Petrophysical Characterization of the Germania Spraberry units requires a unique approach for a number of reasons--limited core data, lack of modern log data and absence of directed studies within the unit. The need for characterization of the Germania unit has emerged as a first step in the review, understanding and enhancement of the production practices applicable within the unit and the trend area in general. In the absence or lack of the afore mentioned resources, an approach that will rely heavily on previous petrophysical work carried out in the neighboring ET O'Daniel unit (6.2 miles away), and normalization of the old log data prior to conventional interpretation techniques will be used. A log-based rock model has been able to guide successfully the prediction of pay and non-pay intervals within the ET O'Daniel unit, and will be useful if found applicable within the Germania unit. A novel multiple regression technique utilizing non-parametric transformations to achieve better correlations in predicting a dependent variable (permeability) from multiple independent variables (rock type, shale volume and porosity) will also be investigated in this study. A log data base includes digitized formats of Gamma Ray, Cased Hole Neutron, limited Resistivity and Neutron/Density/Sonic porosity logs over a considerable wide area. In addition, a progress report on GSU waterflood pilot is reported for this period. We have seen positive response of water injection on new wells. We believe by proper data acquisition and precise reservoir engineering techniques, any lack of confidence in waterflooding can be overcome. Therefore, we develop field management software to control a vast data from the pilot and to perform precise reservoir engineering techniques such as decline curve analysis, gas and oil material balances, bubble map plot and PVT analysis. The manual for this software is listed in the Appendix-A.

Paraffin control in the Northern Michigan Niagaran reef trend  

SciTech Connect (OSTI)

Wax deposition on downhole equipment and in chokes, flowlines, separators, dehydration and storage equipment is a costly problem in the northern Michigan area called the Niagaran Reef trend. A number of mechanical removal techniques have been used to treat for paraffin. Among these are paraffin cutters, plunger lift, rod scrapers, hot oil or water, plastic coatings, and flowline pigging. Improvements in chemical formulation, testing, and applications have resulted in a number of economically successful chemical programs for paraffin control. Examples of field problems and solutions are presented.

Patient exposure trends in medical and dental radiography  

SciTech Connect (OSTI)

Patient exposure to medical and dental x rays has long been of interest to the radiological health community. With the cooperation of state and local agencies and professional groups, the Center for Devices and Radiological Health has conducted three major surveys of patient exposure to x rays. The latest of these surveys, the Nationwide Evaluation of X-ray Trends (NEXT), collected x-ray exposure data for each year starting in 1972. Two earlier studies, the 1964 and 1970 X-ray Exposure Studies collected x-ray data during the years these surveys were conducted. Exposure trends presented are based on results of all three studies. Major improvements in beam limitation are seen for medical and dental radiography. Since 1964, when the first nationwide survey was conducted, dental exposures have decreased about 75%. Decreases of up to one-third occurred in exposures for medical examinations. The current exposure data presented continue to show a wide variation in medical exposures. Also presented are organ doses for four organs (ovaries, testes, thyroid and active bone marrow).

SPECTROSCOPIC METALLICITY DETERMINATIONS FOR W UMa-TYPE BINARY STARS  

SciTech Connect (OSTI)

This study is the first attempt to determine the metallicities of W UMa-type binary stars using spectroscopy. We analyzed about 4500 spectra collected at the David Dunlap Observatory. To circumvent problems caused by the extreme spectral line broadening and blending and by the relatively low quality of the data, all spectra were subject to the same broadening function (BF) processing to determine the combined line strength in the spectral window centered on the Mg I triplet between 5080 A and 5285 A. All individual integrated BFs were subsequently orbital-phase averaged to derive a single line-strength indicator for each star. The star sample was limited to 90 W UMa-type (EW) binaries with the strict phase-constancy of colors and without spectral contamination by spectroscopic companions. The best defined results were obtained for an F-type sub-sample (0.32 < (B - V){sub 0} < 0.62) of 52 binaries for which integrated BF strengths could be interpolated in the model atmosphere predictions. The logarithmic relative metallicities, [M/H], for the F-type sub-sample indicate metal abundances roughly similar to the solar metallicity, but with a large scatter which is partly due to combined random and systematic errors. Because of the occurrence of a systematic color trend resulting from inherent limitations in our approach, we were forced to set the absolute scale of metallicities to correspond to that derived from the m{sub 1} index of the Stroemgren uvby photometry for 24 binaries of the F-type sub-sample. The trend-adjusted metallicities [M/H]{sub 1} are distributed within -0.65 < [M/H]{sub 1} < +0.50, with the spread reflecting genuine metallicity differences between stars. One half of the F-sub-sample binaries have [M/H]{sub 1} within -0.37 < [M/H]{sub 1} < +0.10, a median of -0.04 and a mean of -0.10, with a tail toward low metallicities, and a possible bias against very high metallicities. A parallel study of kinematic data, utilizing the most reliable and recently obtained proper motion and radial velocity data for 78 binaries of the full sample, shows that the F-type sub-sample binaries (44 stars with both velocities and metallicity determinations) have similar kinematic properties to solar-neighborhood, thin-disk dwarfs with space velocity component dispersions: {sigma}U = 33 km s{sup -1}, {sigma}V = 23 km s{sup -1} and {sigma}W = 14 km s{sup -1}. FU Dra with a large spatial velocity, V{sub tot} = 197 km s{sup -1} and [M/H]{sub 1} = -0.6 {+-} 0.2, appears to be the only thick-disk object in the F-type sub-sample. The kinematic data indicate that the F-type EW binaries are typical, thin-disk population stars with ages about 3-5.5 Gyr. The F-type binaries that appear to be older than the rest tend to have systematically smaller mass ratios than most of the EW binaries of the same period.

Integrated scenario analysis for metal surface treatment  

Science Journals Connector (OSTI)

As a result of new environmental legislation (EU-Solvent Directive, Directive on Integrated Pollution Prevention and Control IPPC), numerous companies from the metal surface treatment sector must reduce their emissions of organic solvents. Small enterprises will mainly employ alternative coating products with a lower content of organic solvents in process integrated measures. In large installations, improved end of pipe technologies such as waste gas treatment and application of alternative paints are utilised to meet the new emission limit values. These efforts together with tough competition on the market will lead to far-reaching changes within the sector. Predictions on future changes in the organisation and functioning of the value chain can be assisted via the methods of scenario analyses which are based on the examination of possible trends. The vertical integration of the value chain, which leads to an increasing number of large service providers that produce and apply coating materials, seems very probable. Also, a decreased number of small and medium

Plasma formation in metallic wire Z pinches  

Science Journals Connector (OSTI)

Plasma formation in metallic wire Z pinches is modeled using a two-dimensional resistive magnetohydrodynamics code. Modified Thomas-Fermi equations of state and dense plasma transport coefficients allow the phase transitions from solid to plasma to be approximated. Results indicate the persistence of a two-component structure with a cold, dense core embedded within a much hotter, low density, m=0 unstable corona. Extensive benchmark testing against data from a number of single-wire experiments is presented. Artificial laser schlieren and x-ray back-lighting images generated from the code data are compared directly to experimental results. The results were found to be insensitive to inaccuracies in the equations of state and transport coefficients. Simulations of individual wires in a wire array show different behavior to that observed experimentally due to the absence of three-dimensional effects. Simulations with similar conditions to wires in an array show a general trend in the plasma structure at start of implosion from discrete wires with large m=0 perturbation amplitudes to partially merged wires with smaller perturbation amplitudes as the number of wires is increased. Results for a wire number scan with aluminum wire arrays on the SATURN generator suggest that the observed sharp transition to high x-ray power at around 40 wires corresponds to a sharp decrease in m=0 perturbation amplitude and hence a sharp decrease in the seed perturbation for the Rayleigh-Taylor instability.

International Recycling of LLW Metals  

SciTech Connect (OSTI)

Melting of radioactive scrap metal has been successfully practiced for more than 15 years, with approximately 60,000 tons of steel being processed into beneficial reuse applications. This process has converted radioactive scrap metal at a licensed facility into useful products such as shield blocks, security barriers and shield containers. These products are used within the nuclear industry, such as nuclear power plants, waste disposal facilities and high-energy physics research facilities. Recycling provides the following benefits by comparison with direct disposal: - Preserving metal resources. - Conserving valuable Low Level Waste (LLW) disposal site resources, thereby extending disposal site life. - Reducing the cost of metal products to end users by using materials less expensive than virgin metals. This paper outlines international metal recycling practices implemented at EnergySolutions' Bear Creek Facility in Oak Ridge, Tennessee. (authors)

Clean Metal Casting  

SciTech Connect (OSTI)

The objective of this project is to develop a technology for clean metal processing that is capable of consistently providing a metal cleanliness level that is fit for a given application. The program has five tasks: Development of melt cleanliness assessment technology, development of melt contamination avoidance technology, development of high temperature phase separation technology, establishment of a correlation between the level of melt cleanliness and as cast mechanical properties, and transfer of technology to the industrial sector. Within the context of the first task, WPI has developed a standardized Reduced Pressure Test that has been endorsed by AFS as a recommended practice. In addition, within the context of task1, WPI has developed a melt cleanliness sensor based on the principles of electromagnetic separation. An industrial partner is commercializing the sensor. Within the context of the second task, WPI has developed environmentally friendly fluxes that do not contain fluorine. Within the context of the third task, WPI modeled the process of rotary degassing and verified the model predictions with experimental data. This model may be used to optimize the performance of industrial rotary degassers. Within the context of the fourth task, WPI has correlated the level of melt cleanliness at various foundries, including a sand casting foundry, a permanent mold casting foundry, and a die casting foundry, to the casting process and the resultant mechanical properties. This is useful in tailoring the melt cleansing operations at foundries to the particular casting process and the desired properties of cast components.

``Towards Strange Metallic Holography'  

SciTech Connect (OSTI)

We initiate a holographic model building approach to 'strange metallic' phenomenology. Our model couples a neutral Lifshitz-invariant quantum critical theory, dual to a bulk gravitational background, to a finite density of gapped probe charge carriers, dually described by D-branes. In the physical regime of temperature much lower than the charge density and gap, we exhibit anomalous scalings of the temperature and frequency dependent conductivity. Choosing the dynamical critical exponent z appropriately we can match the non-Fermi liquid scalings, such as linear resistivity, observed in strange metal regimes. As part of our investigation we outline three distinct string theory realizations of Lifshitz geometries: from F theory, from polarized branes, and from a gravitating charged Fermi gas. We also identify general features of renormalization group flow in Lifshitz theories, such as the appearance of relevant charge-charge interactions when z {ge} 2. We outline a program to extend this model building approach to other anomalous observables of interest such as the Hall conductivity.

DOE Patents [OSTI]

Methods of forming a conductive metal layers on substrates are disclosed which employ a seed layer to enhance bonding, especially to smooth, low-roughness or hydrophobic substrates. In one aspect of the invention, the seed layer can be formed by applying nanoparticles onto a surface of the substrate; and the metallization is achieved by electroplating an electrically conducting metal onto the seed layer, whereby the nanoparticles serve as nucleation sites for metal deposition. In another approach, the seed layer can be formed by a self-assembling linker material, such as a sulfur-containing silane material.

Changes in worldwide demand for metals (final). Open File report  

SciTech Connect (OSTI)

Worldwide demand for metals was analyzed to identify the important factors that explain differences in the level of demand among world countries. The per capita demand for steel, aluminum, copper, and total nonferrous metals was investigated for 40 to 50 countries over a 22-year period. These countries have been further grouped into four world regions for purposes of making generalizations about the importance of these factors for countries in different stages of development and with dissimilar levels of per capita gross domestic product (GDP). Intercountry and intertemporal differences are explained largely by differences in per capita GDP and changes over time in per capita GDP, oil real prices, and to a lesser extent, metal real prices. The trend in world consumption is dramatically different in the last decade than the previous one. In 1962-73, per capita consumption increased in all areas and consumption intensity (consumption divided by (GDP) increased in most areas). In 1973-84, per capita consumption fell in most areas and intensity fell dramatically, except in developing nations.

Metal contacts on ZnSe and GaN  

SciTech Connect (OSTI)

Recently, considerable interest has been focused on the development of blue light emitting materials and devices. The focus has been on GaN and ZnSe, direct band gap semiconductors with bands gaps of 3.4 and 2.6 eV, respectively. To have efficient, reliable devices it is necessary to have thermally and electrically stable Ohmic contacts. This requires knowledge of the metal-semiconductor reaction behavior. To date few studies have investigated this behavior. Much information has accumulated over the years on the behavior of metals on Si and GaAs. This thesis provides new knowledge for the more ionic wide band gap semiconductors. The initial reaction temperatures, first phases formed, and phase stability of Pt, Pd, and Ni on both semiconductors were investigated. The reactions of these metals on ZnSe and GaN are discussed in detail and correlated with predicted behavior. In addition, comparisons are made between these highly ionic semiconductors and Si and GaAs. The trends observed here should also be applicable to other II-VI and III-Nitride semiconductor systems, while the information on phase formation and stability should be useful in the development of contacts for ZnSe and GaN devices.

Trends and Future Challenges in Sampling the Deep Terrestrial Biosphere  

SciTech Connect (OSTI)

Research in the deep terrestrial biosphere is driven by interest in novel biodiversity and metabolisms, biogeochemical cycling, and the impact of human activities on this ecosystem. As this interest continues to grow, it is important to ensure that when subsurface investigations are proposed, materials recovered from the subsurface are sampled and preserved in an appropriate manner to limit contamination and ensure preservation of accurate microbial, geochemical, and mineralogical signatures. On February 20th, 2014, a workshop on Trends and Future Challenges in Sampling The Deep Subsurface was coordinated in Columbus, Ohio by The Ohio State University and West Virginia University faculty, and sponsored by The Ohio State University and the Sloan Foundations Deep Carbon Observatory. The workshop aims were to identify and develop best practices for the collection, preservation, and analysis of terrestrial deep rock samples. This document summarizes the information shared during this workshop.

SciTech Connect (OSTI)

This report is a summary of the finance trends for small-scale solar photovoltaic (PV) projects (PV <1 MW), large-scale PV projects (PV greater than or equal to 1 MW), and concentrated solar power projects as reported in the National Renewable Energy Laboratory's Renewable Energy Finance Tracking Initiative (REFTI). The report presents REFTI data during the five quarterly periods from the fourth quarter of 2009 to the first half of 2011. The REFTI project relies exclusively on the voluntary participation of industry stakeholders for its data; therefore, it does not offer a comprehensive view of the technologies it tracks. Despite this limitation, REFTI is the only publicly available resource for renewable energy project financial terms. REFTI analysis offers usable inputs into the project economic evaluations of developers and investors, as well as the policy assessments of public utility commissions and others in the renewable energy industry.

We present the results of electrical resistivity and optical absorption measurements for compositions spanning the metal-insulator transition in RbKr and CsXe alloys. The two transitions are similar and exhibit an apparently percolative character. No marked emergence of excitons accompanies the disappearance of conductivity. Spectral features associated with metallic conduction also persist through the transitions.

The small structure in the conductance curve near zero bias of metal-insulator-metal tunnel junctions has been studied extensively. These experiments are analyzed in detail in a nonequilibrium model. It is shown that this type of zero-bias anomaly can be accounted for entirely by an electron bottleneck arising from the blocking of tunneling states due to nonzero electron relaxation times.

Morphological abnormalities in chironomidae in relation to sediment metals concentrations in Empire Lake, Cherokee County, Kansas  

SciTech Connect (OSTI)

Morphological abnormalities of headcapsule structures of chironomid larvae were quantified in relation to concentrations of heavy metals in sediments of Empire Lake. This reservoir is situated in a catchment downstream of a US EPA Superfund Site in the Tri-State Mining District of southeast Kansas, and receives discharges from several streams that flow through the abandoned mining areas. Sediments have elevated concentrations of Zinc, Lead, and Cadmium in varying concentrations. Chironomini had the highest incidence of morphological abnormalities, followed by Procladius. Although deformities of the mentum, premandibles, and antennae were found in several taxa, no clear trends were seen for increasing concentrations of any of the metals individually or collectively. From this study it appears as if the incidence of morphological abnormalities is not a linear function of metals concentrations in sediments of this reservoir.

Inorganic concepts relevant to metal binding, activity, and toxicity in a biological system  

SciTech Connect (OSTI)

The purpose of this paper is to review selected physical and inorganic concepts and factors which might be important in assessing and/or understanding the fact and disposition of a metal system in a biological environment. Hopefully, such inquiries will ultimately permit us to understand, rationalize, and predict differences and trends in biological effects as a function of the basic nature of a metal system and, in optimal cases, serve as input to a system of guidelines for the notion of Chemical Dosimetry.'' The plan of this paper is to first review, in general terms, the basic principles of the Crystal Field Theory (CFT), a unifying theory of bonding in metal complexes. This will provide the necessary theoretical background for the subsequent discussion of selected concepts and factors. 21 refs., 7 figs., 6 tabs.

Assessing the consistency between short-term global temperature trends in observations and climate model projections  

E-Print Network [OSTI]

Assessing the consistency between short-term global temperature trends in observations and climate model projections is a challenging problem. While climate models capture many processes governing short-term climate fluctuations, they are not expected to simulate the specific timing of these somewhat random phenomena - the occurrence of which may impact the realized trend. Therefore, to assess model performance, we develop distributions of projected temperature trends from a collection of climate models running the IPCC A1B emissions scenario. We evaluate where observed trends of length 5 to 15 years fall within the distribution of model trends of the same length. We find that current trends lie near the lower limits of the model distributions, with cumulative probability-of-occurrence values typically between 5 percent and 20 percent, and probabilities below 5 percent not uncommon. Our results indicate cause for concern regarding the consistency between climate model projections and observed climate behavior...

Cation-Bonding and Protonation of the Fe[subscript 4]-Square Cluster  

SciTech Connect (OSTI)

The synthesis and characterization of discrete, molecular iron-oxo clusters is pursued in the interest of molecular magnets, bioinspired materials and models for the geochemical aqueous-mineral interface. Iron-oxo clusters are challenging to synthesize in water, due to the extremely acidic and reactive nature of dissolved iron species, and thus require chelating ligands to passivate and neutralize the cluster surface. The 2-hydroxy-1,3-N,N,N',N'-diamino-propanetetraacetic acid (HPDTA) ligand has been used to isolate several Al and Fe cluster geometries, including the square clusters Fe{sub 4}(HPDTA){sub 2} and Al{sub 4}(HPDTA){sub 2}. While prior reports on the Fe{sub 4}(HPDTA){sub 2} cluster have focused on the magnetic properties, no solution characterization has been carried out. Using electrospray ionization mass-spectrometry (ESI-MS) we show this anionic Fe{sub 4}(HPDTA){sub 2} cluster can be dissolved intact in water, and recrystallized with virtually any metal as a countercation. The bonding of the metal cation to the square face of the cluster trends with ionic radii of the cations, as shown by structural characterization of Fe{sub 4}(HPDTA){sub 2} with Li{sup +}, Na{sup +}, Cs{sup +}, Mg{sup 2+}, Ba{sup 2+}, La{sup 3+}, Eu{sup 3+}, and Zn{sup 2+}. This trend is similar to that observed for association of cations on metal oxide surfaces in the environment. Furthermore, protonation of the bridging oxo ligands of this series of Fe{sub 4}(HPDTA){sub 2} clusters is variable (0, 1, or 2 protons), and structures as a function of protonation is discussed. This paper, largely structural in nature, sets the foundation for future aqueous phase studies of iron-oxo molecular clusters as models for the oxide-water interface in the natural aqueous environment.

Trends in fireside corrosion damage to superheaters in air and oxy-firing of coal/biomass  

Science Journals Connector (OSTI)

Abstract This paper compares the laboratory-based fireside corrosion tests on superheater/reheater materials in simulated air-firing combustion conditions with oxy-firing combustion conditions (with hot gas recycling before flue gas de-sulphurisation). The gaseous combustion environment was calculated based on a specific co-firing ratio of CCP with Daw Mill coal. The fireside corrosion tests were carried out using the deposit recoat test method to simulate the damage anticipated in specific environments. A synthetic deposit (Na2SO4:K2SO4:Fe2O3=1.5:1.5:1mol.) which has commonly been used in fireside corrosion screening trials and is a mix that forms alkali-iron tri-sulphate (identified in many investigations as a cause of fireside corrosion) was used in these tests. The air-fired tests were carried out at temperatures of 600, 650 and 700C and oxy-fired tests were carried out at temperatures of 600, 650, 700 and 750C to represent the superheater/reheater metal temperatures anticipated in future power plants with and without synthetic deposits, with four candidate materials: T92, HR3C and 347HFG steels; nickel-based alloy 625 (alloy 625 was only tested with screening deposits). The progress of the samples during their exposures was measured using mass change methods. After the exposures, the samples were examined by SEM/EDX to characterise the damage. To quantify the metal damage, pre-exposure micrometre measurements were compared to the post-exposure image analyser measurements on sample cross-sections. The trends in corrosion damage in both air and oxy-firing conditions showed a bell-shaped curve, with the highest metal damage levels (peak) observed at 650C for air-firing and 700C for oxy-firing tests. However, at 600 and 650C similar damage levels were observed in both environments. The shift in peak corrosion damage in oxy-firing condition is believed to be the presence of higher levels of SOx, which stabilised the alkali-iron tri-sulphate compounds. Generally, in both air and oxy-firing conditions the mean metal damage was reduced with increasing the amount of Cr in the alloys. However, at the highest temperatures in both air-firing (700C) and oxy-firing conditions (750C) the metal damage of nickel based superalloy 625 was higher than HR3C.

Catalytic production of metal carbonyls from metal oxides  

DOE Patents [OSTI]

This invention relates to the formation of metal carbonyls from metal oxides and specially the formation of molybdenum carbonyl and iron carbonyl from their respective oxides. Copper is used here in admixed form or used in chemically combined form as copper molybdate. The copper/metal oxide combination or combined copper is utilized with a solvent, such as toluene and subjected to carbon monoxide pressure of 25 atmospheres or greater at about 150 to 260/sup 0/C. The reducing metal copper is employed in catalytic concentrations or combined concentrations as CuMoO/sub 4/ and both hydrogen and water present serve as promoters. It has been found that the yields by this process have been salutary and that additionally the catalytic metal may be reused in the process to good effect. 3 tables.

Unexpected increasing AOT trends over northwest Bay of Bengal in the early postmonsoon season  

SciTech Connect (OSTI)

The main point of our study is that aerosol trends can be created by changes in meteorology without changes in aerosol source strength. Over the 10 year period 20002009, in October, Moderate Resolution Imaging Spectroradiometer (MODIS) showed strong increasing aerosol optical thickness (AOT) trends of approximately 14% yr-1 over northwest Bay of Bengal (BoB) in the absence of AOT trends over the east of the Indian subcontinent. This was unexpected because sources of anthropogenic pollution were located over the Indian subcontinent and aerosol transport from the Indian subcontinent to northwest BoB was carried out by prevailing winds. In October, winds over the east of the Indian subcontinent were stronger than winds over northwest BoB, which resulted in wind convergence and accumulation of aerosol particles over northwest BoB. Moreover, there was an increasing trend in wind convergence over northwest BoB. This led to increasing trends in the accumulation of aerosol particles over northwest BoB and, consequently, to strong AOT trends over this area. In contrast to October, November showed no increasing AOT trends over northwest BoB or the nearby Indian subcontinent. The lack of AOT trends over northwest BoB corresponds to a lack of trends in wind convergence in that region. Finally, December domestic heating by the growing population resulted in positive AOT trends of similar magnitude over land and sea. Our findings illustrate that in order to explain and predict trends in regional aerosol loading, meteorological trends should be taken into consideration together with changes in aerosol source strength.

Creating bulk nanocrystalline metal.  

SciTech Connect (OSTI)

Nanocrystalline and nanostructured materials offer unique microstructure-dependent properties that are superior to coarse-grained materials. These materials have been shown to have very high hardness, strength, and wear resistance. However, most current methods of producing nanostructured materials in weapons-relevant materials create powdered metal that must be consolidated into bulk form to be useful. Conventional consolidation methods are not appropriate due to the need to maintain the nanocrystalline structure. This research investigated new ways of creating nanocrystalline material, new methods of consolidating nanocrystalline material, and an analysis of these different methods of creation and consolidation to evaluate their applicability to mesoscale weapons applications where part features are often under 100 {micro}m wide and the material's microstructure must be very small to give homogeneous properties across the feature.

The Halo Stars in NGC 5128. III: An Inner-Halo Field and the Metallicity Distribution  

E-Print Network [OSTI]

We present new HST/WFPC2 (V,I) photometry for the red-giant stars in NGC 5128 at a projected distance of 8 kpc from the galaxy center, which probe a mixture of its inner halo and outer bulge. The color-magnitude diagram shows an old red-giant branch which is even broader in color than our two previously studied outer-halo fields (at 21 and 31 kpc), with significant numbers of stars extending to Solar metallicity and higher. The peak frequency of the metallicity distribution function (MDF) is at [m/H] ~ -0.4, with even fewer metal-poor stars than in the outer-halo fields. We find that the main features of the halo MDF can be reproduced by a simple chemical evolution model in which early star formation goes on simultaneously with an initial stage of rapid infall of very metal-poor gas, after which the infall dies away exponentially. A comparison with the MDF for the NGC 5128 globular clusters indicates that there is a clear decrease of specific frequency $S_N$ (number of clusters per unit halo light) with increasing metallicity, from S_N ~ 4-8 at [Fe/H] -1. This trend may indicate that globular cluster formation efficiency is a strong function of the metallicity of the protocluster gas.

Heavy metals in the eastern oyster, Crassostrea virginica, of the Mississippi Sound  

SciTech Connect (OSTI)

Levels of metals in oysters in the Sound are of profound interest not only because they document those geographic areas where metal pollution levels may be problematic but because they may disclose possible problems to consumers of oysters. At the present time objective federal standards for heavy metals in oysters and other seafood are restricted to mercury. The closure of Mississippi oyster reefs has been predicated upon bacteriological standards with little if any attention paid to heavy metals. A study of fourteen metals in oysters of the Sound was began in 1988 with objectives differing from that of the Status and Trends Program (STP) in three ways. STP levels are reported on dry weight basis of composites from three sites. In the present study, oysters were analyzed and reported on wet weight basis. Additionally analyses were made of individual specimens to indicate expected specimen to specimen variations and were conducted on oysters from the three STP and two other important oyster reef sites. In the future three or more additional sites will be added to this continuing survey effort. Metals chosen for this study were lead (Pb), cadmium (Cd), iron (Fe), copper (Cu), cobalt (Co), manganese (Mn), zinc (Zn), silver (Ag), nickel (Ni), mercury (Hg), aluminum (Al), chromium (Cr), molybdenum (Mo), and vanadium (V).

Durability of metals from archaeological objects, metal meteorites, and native metals  

SciTech Connect (OSTI)

Metal durability is an important consideration in the multi-barrier nuclear waste storage concept. This study summarizes the ancient metals, the environments, and factors which appear to have contributed to metal longevity. Archaeological and radiochemical dating suggest that human use of metals began in the period 6000 to 7000 BC. Gold is clearly the most durable, but many objects fashioned from silver, copper, bronze, iron, lead, and tin have survived for several thousand years. Dry environments, such as tombs, appear to be optimum for metal preservation, but some metals have survived in shipwrecks for over a thousand years. The metal meteorites are Fe-base alloys with 5 to 60 wt% Ni and minor amounts of Co, I, and S. Some meteoritic masses with ages estimated to be 5,000 to 20,000 years have weathered very little, while other masses from the same meteorites are in advanced stages of weathering. Native metals are natural metallic ores. Approximately five million tonnes were mined from native copper deposits in Michigan. Copper masses from the Michigan deposits were transported by the Pleistocene glaciers. Areas on the copper surfaces which appear to represent glacial abrasion show minimal corrosion. Dry cooling tower technology has demonstrated that in pollution-free moist environments, metals fare better at temperatures above than below the dewpoint. Thus, in moderate temperature regimes, elevated temperatures may be useful rather than detrimental for exposures of metal to air. In liquid environments, relatively complex radiolysis reactions can occur, particularly where multiple species are present. A dry environment largely obviates radiolysis effects.

Phyto remediation groundwater trends at the DOE portsmouth gaseous  

SciTech Connect (OSTI)

This paper describes the progress of a phyto-remediation action being performed at the Department of Energy (DOE) Portsmouth Gaseous Diffusion Plant (PORTS) X-740 Waste Oil Handling Facility to remediate contaminated groundwater under a Resource Conservation and Recovery Act (RCRA) closure action. This action was effected by an Ohio Environmental Protection Agency (OEPA) decision to use phyto-remediation as the preferred remedy for the X-740 groundwater contamination. This remedy was recognized as a cost-effective, low-maintenance, and promising method to remediate groundwater contaminated with volatile organic compounds (VOCs), primarily trichloroethylene (TCE). During 1999, prior to the tree installation at the X-740 Phyto-remediation Area, water level measurements in the area were collected from 10 monitoring wells completed in the Gallia Formation. The Gallia is the uppermost water-bearing zone and contains most of the groundwater contamination at PORTS. During the tree installation which took place during the summer of 1999, four new Gallia monitoring wells were installed at the X-740 Area in addition to the 10 Gallia wells which had been installed in the same area during the early 1990's. Manual water level measurements were collected quarterly from these 14 Gallia monitoring wells between 1998 and 2001. These manual water level measurements were collected to monitor the combined impact of the trees on the groundwater prior to root development. Beginning in 2001, water level measurements were collected monthly during the growing season (April-September) and quarterly during the dormant season (October-March). A total of eight water level measurements were collected annually to monitor the phyto-remediation system's effect on the groundwater in the X- 740 Area. The primary function of the X-740 Phyto-remediation Area is to hydraulically prevent further spreading of the TCE plume. This process utilizes deep-rooted plants, such as poplar trees, to extract large quantities of water from the saturated zone. The focus of any phyto-remediation system is to develop a cone of depression under the entire plantation area. This cone of depression can halt migration of the contaminant plume and can create a hydraulic barrier, thereby maintaining plume capture. While a cone of depression is not yet evident at the X-740 Phyto-remediation Area, water level measurements in 2004 and 2005 differed from measurements taken in previous years, indicating that the now mature trees are influencing groundwater flow direction and gradient at the site. Water level measurements taken from 2003 through 2005 indicate a trend whereby groundwater elevations steadily decreased in the X-740 Phyto-remediation System. During this time, an average groundwater table drop of 0.30 feet was observed. Although the time for the phyto-remediation system to mature had been estimated at two to three years, these monitoring data indicate a period of four to five years for the trees to reach maturity. Although, these trends are not apparent from analysis of the potentiometric surface contours, it does appear that the head gradient across the site is higher during the spring and lower during the fall. It is not clear, however, whether this trend was initiated by the installation of the phyto-remediation system. This paper will present the groundwater data collected to date to illustrate the effects of the trees on the groundwater table. (authors)

Bad Metals Made with Good-Metal Components  

Science Journals Connector (OSTI)

We have grown thin stable films of a good metal, Ag, that have characteristics of bad metals: high resistivity, strong temperature dependence of resistivity, and lack of resistive saturation. For films of different thickness, the temperature-dependent resistance and the Hall effect resistance provide evidence that the apparent bad metallicity is a consequence of the microstructure of the film rather than the result of new physics. This microstructure, which we characterize with scanning probe techniques, occurs on length scales comparable to the mean free path, thereby changing the sign of the classical magnetoresistance from positive to negative.

Metal-based reactive nanomaterials  

Science Journals Connector (OSTI)

Recent developments in materials processing and characterization resulted in the discovery of a new type of reactive materials containing nanoscaled metal components. The well-known high oxidation energies of metallic fuels can now be released very rapidly because of the very high reactive interface areas in such metal-based reactive nanomaterials. Consequently, these materials are currently being examined for an entire range of applications in energetic formulations inappropriate for conventional, micron-sized metal fuels having relatively low reaction rates. New application areas, such as reactive structural materials, are also being explored. Research remains active in manufacturing and characterization of metal-based reactive nanomaterials including elemental metal nanopowders and various nanocomposite material systems. Because of the nanometer scale of the individual particles, or phase domains, and because of the very high enthalpy of reaction between components of the nanocomposite materials, the final phase compositions, morphology, and thermodynamic properties of the reactive nanocomposite materials may be different from those of their micron-scaled counterparts. Ignition mechanisms in such materials can be governed by heterogeneous reactions that are insignificant for materials with less developed reactive interface areas. New combustion regimes are being observed that are affected by very short ignition delays combined with very high metal combustion temperatures. Current progress in this rapidly growing research area is reviewed and some potential directions for the future research are discussed.

Metal-doped organic foam  

DOE Patents [OSTI]

Organic foams having a low density and very small cell size and method for producing same in either a metal-loaded or unloaded (nonmetal loaded) form are described. Metal-doped foams are produced by soaking a polymer gel in an aqueous solution of desired metal salt, soaking the gel successively in a solvent series of decreasing polarity to remove water from the gel and replace it with a solvent of lower polarity with each successive solvent in the series being miscible with the solvents on each side and being saturated with the desired metal salt, and removing the last of the solvents from the gel to produce the desired metal-doped foam having desired density cell size, and metal loading. The unloaded or metal-doped foams can be utilized in a variety of applications requiring low density, small cell size foam. For example, rubidium-doped foam made in accordance with the invention has utility in special applications, such as in x-ray lasers.

Synthesis and Exploratory Catalysis of 3d Metals: Group-Transfer Reactions, and the Activation and Functionalization of Small Molecules Including Greenhouse Gases  

SciTech Connect (OSTI)

Our work over the past three years has resulted in the development of electron rich and low-coordinate vanadium fragments, molecular nitrides of vanadium and parent imide systems of titanium, and the synthesis of phosphorus containing molecules of the 3d transition metal series. Likewise, with financial support from BES Division in DOE (DE-FG02-07ER15893), we now completed the full characterization of the first single molecular magnet (SMM) of Fe(III). We demonstrated that this monomeric form of Fe(III) has an unusual slow relaxation of the magnetization under zero applied field. To make matters more interesting, this system also undergoes a rare example of an intermediate to high-spin transition (an S = 3/2 to S = 5/2 transition). In 2010 we reported the synthesis of the first neutral and low-coordinate vanadium complexes having the terminal nitride functionality. We have now completed a full study to understand formation of the nitride ligand from the metastable azide precursor, and have also explored the reactivity of the nitride ligand in the context of incomplete and complete N-atom transfer. During the 2010-2013 period we also discovered a facile approach to assemble low-coordinate and low-valent vanadium(II) complexes and exploit their multielectron chemistry ranging from 1-3 electrons. Consequently, we can now access 3d ligand frameworks such as cyclo-P3 (and its corresponding radical anion), nitride radical anions and cations, low-coordinate vanadium oxos, and the first example of a vanadium thionitrosyl complex. A cis-divacant iron(IV) imido having some ligand centered radical has been also discovered, and we are in the process of elucidating its electronic structure (in particular the sign of zero field splitting and the origin of its magnitude), bonding and reactivity. We have also revisited some paramagnetic and classic metallocene compounds with S >1/2 ground states in order to understand their reactivity patterns and electronic structure. Lastly, we are completing the synthesis and characterization of a titanium nitride anion and formation of the first example of boryl and aluminyl imido titanium complexes.

Solar grade silicon: Technology status and industrial trends  

Science Journals Connector (OSTI)

Abstract Crystalline silicon remains (all variants included) the dominant technology to manufacture solar cells. Currently (20122013) more than 90% of all solar cells produced are based on this vast group of technologies. The availability, the cost and the quality to the silicon feedstock is therefore a strategic issue of paramount importance for the entire photovoltaic sector. The silicon demand/supply balance has evolved from a situation of shortage with rocketing sales prices, in the years 20052008, to currently (20122013) an oversupply situation with record low price level for virgin polysilicon. Between these two extreme periods, production capacity has been multiplied by a factor of nearly 10. A better understanding of the prevailing dynamics in the polysilicon/silicon industry is needed in order for all players in the solar cell industry to make proper planning. In light of the past developments as well as the constraints imposed by a sound competition, the present article reviews the market trends for solar grade silicon including capacity, supply, demand and price. Furthermore, the article reviews the competing commercial technologies i.e. Siemens polysilicon, fluidized bed reactor/FBR polysilicon and upgraded metallurgical/UMG silicon and compares them in terms of maturity, improvement potential, product morphology, purity, applications and cost (actual vs. potential).

Trends and trade-offs in petroleum tax design  

Science Journals Connector (OSTI)

How should tax systems be designed to account for the characteristics of the government, the oil companies and the projects in order to maximise welfare for the country's inhabitants? How should vital government characteristics reflected in parameters such as impatience to obtain tax revenue - the discount rate - and the willingness and ability to carry risk be accounted for in tax design? These basic issues in petroleum tax design are discussed by means of a tax model for a discretionary licensing regime (Norway) and a production sharing agreement regime (Angola). The analysis covers the entire life cycle of a typical petroleum project, i.e., including the exploration decision. We discuss the trade-off between progressivity on the one hand and the incentive for the oil companies and the host government to carry risk and investment on the other. Thus, we provide basic elements in a state contingent tax design. The paper also surveys trends in petroleum taxation, and discusses how tax elements vary over the business cycle.

Nonmetal-metal transition in metalmolten-salt solutions  

Science Journals Connector (OSTI)

The method of ab initio molecular dynamics, based on finite-temperature density-functional theory, is used to study the nonmetal-metal transition in two different metalmolten-salt solutions, Kx(KCl)1-x and Nax(NaBr)1-x. As the excess metal concentration is increased the electronic density becomes delocalized and percolating conducting paths are formed, making a significant dc electrical conductivity possible. This marks the onset of the metallic regime. By calculating several electronic and structural properties, remarkable differences between the two solutions are observed. The anomalous behavior of Nax(NaBr)1-x, typical of all the Na-NaX solutions, is found to be related to the strong attractive interaction between the sodium ions and the excess electrons. 1996 The American Physical Society.

Magnetism in Transition Metals  

Science Journals Connector (OSTI)

An attempt is made to distinguish "band-type magnetization" from "alignment-type magnetization" on the basis of whether the local moments associated with the Wannier functions on the atom sites are "induced" or "permanent." In general, the local moment is partially induced and partially permanent, and a criterion is suggested: A local moment is defined to be of the permanent variety if in the presence of magnetic forces (supposed characteristic of the crystal in a given circumstance) tending to produce a moment in one sense (z^, say) of a direction, it can maintain itself (perhaps altered in magnitude, however) in the opposite sense (-z^), as well as in z^. The internal mechanisms tending to produce permanent moments are simplified to just the Hcorr of Anderson, and the external inducing mechanism are the Heisenberg interaction and a magnetic field, Hspin, say. If Hcorr dominates Hspin, then it is shown that a local moment can maintain itself to the polarizing tendencies (whence an alignment type of magnetization calculation is appropriate), but if Hspin dominates Hcorr, then the local moment has only one sense possible in this environment (and a band type of calculation is appropriate). It is suggested that this distinction is relevant to transition metals.

Doping Graphene with Metal Contacts  

Science Journals Connector (OSTI)

Making devices with graphene necessarily involves making contacts with metals. We use density functional theory to study how graphene is doped by adsorption on metal substrates and find that weak bonding on Al, Ag, Cu, Au, and Pt, while preserving its unique electronic structure, can still shift the Fermi level with respect to the conical point by ?0.5??eV. At equilibrium separations, the crossover from p-type to n-type doping occurs for a metal work function of ?5.4??eV, a value much larger than the graphene work function of 4.5eV. The numerical results for the Fermi level shift in graphene are described very well by a simple analytical model which characterizes the metal solely in terms of its work function, greatly extending their applicability.

Chapter 4 - Recycling Rare Metals  

Science Journals Connector (OSTI)

Abstract The industrial system now utilizes many more elements, especially rare metals, than was the case even a half century ago. Most are not mined for themselves but are obtained as by-products or hitchhikers of the more familiar industrial metals, such as iron, aluminum, copper, nickel, and zinc. This imposes a limit on the production of by-product metals. But in some cases, demand may increase much faster than new supply. This suggests a need for recycling. But the uses of these metals are often in products, such as cell phones, that are mass-produced but where the amount in each individual product is very small. Some uses are also inherently dissipative. This makes recycling very difficult in principle. It constitutes a serious challenge for the future economy. Prices will rise.

Selenophene transition metal complexes  

SciTech Connect (OSTI)

This research shows that selenophene transition metal complexes have a chemistry that is similar to their thiophene analogs. Selenophene coordination has been demonstrated and confirmed by molecular structure in both the {eta}{sup 5}- and the {eta}{sup 1}(Se)-coordination modes. The reaction chemistry of selenophene complexes closely resembles that of the analogous thiophene complexes. One major difference, however, is that selenophene is a better donor ligand than thiophene making the selenophene complexes more stable than the corresponding thiophene complexes. The {sup 77}Se NMR chemical shift values for selenophene complexes fall within distinct regions primarily depending on the coordination mode of the selenophene ligand. In the final paper, the C-H bond activation of {eta}{sup 1}(S)-bound thiophenes, {eta}{sup 1}(S)-benzothiophene and {eta}{sup 1}(Se)-bound selenophenes has been demonstrated. The deprotonation and rearrangement of the {eta}{sup 1}(E)-bound ligand to the carbon bound L-yl complex readily occurs in the presence of base. Reprotonation with a strong acid gives a carbene complex that is unreactive towards nucleophilic attack at the carbene carbon and is stable towards exposure to air. The molecular structure of [Cp(NO)(PPh{sub 3})Re(2-benzothioenylcarbene)]O{sub 3}SCF{sub 3} was determined and contains a Re-C bond with substantial double bond character. Methyl substitution for the thienylcarbene or selenylcarbene gives a carbene that rearranges thermally to give back the {eta}{sup 1}(E)-bound complex. Based on these model reactions, a new mechanism for the H/D exchange of thiophene over the hydrodesulfurization catalyst has been proposed.

Titanium metal: extraction to application  

SciTech Connect (OSTI)

In 1998, approximately 57,000 tons of titanium metal was consumed in the form of mill products (1). Only about 5% of the 4 million tons of titanium minerals consumed each year is used to produce titanium metal, with the remainder primarily used to produce titanium dioxide pigment. Titanium metal production is primarily based on the direct chlorination of rutile to produce titanium tetrachloride, which is then reduced to metal using the Kroll magnesium reduction process. The use of titanium is tied to its high strength-to-weight ratio and corrosion resistance. Aerospace is the largest application for titanium. In this paper, we discuss all aspects of the titanium industry from ore deposits through extraction to present and future applications. The methods of both primary (mining of ore, extraction, and purification) and secondary (forming and machining) operations will be analyzed. The chemical and physical properties of titanium metal will be briefly examined. Present and future applications for titanium will be discussed. Finally, the economics of titanium metal production also are analyzed as well as the advantages and disadvantages of various alternative extraction methods.

RECENT TRENDS IN EMERGING TRANSPORTATION FUELS AND ENERGY CONSUMPTION  

SciTech Connect (OSTI)

Abundance of energy can be improved both by developing new sources of fuel and by improving efficiency of energy utilization, although we really need to pursue both paths to improve energy accessibility in the future. Currently, 2.7 billion people or 38% of the world s population do not have access to modern cooking fuel and depend on wood or dung and 1.4 billion people or 20% do not have access to electricity. It is estimated that correcting these deficiencies will require an investment of $36 billion dollars annually through 2030. In growing economies, energy use and economic growth are strongly linked, but energy use generally grows at a lower rate due to increased access to modern fuels and adaptation of modern, more efficient technology. Reducing environmental impacts of increased energy consumption such as global warming or regional emissions will require improved technology, renewable fuels, and CO2 reuse or sequestration. The increase in energy utilization will probably result in increased transportation fuel diversity as fuels are shaped by availability of local resources, world trade, and governmental, environmental, and economic policies. The purpose of this paper is to outline some of the recently emerging trends, but not to suggest winners. This paper will focus on liquid transportation fuels, which provide the highest energy density and best match with existing vehicles and infrastructure. Data is taken from a variety of US, European, and other sources without an attempt to normalize or combine the various data sources. Liquid transportation fuels can be derived from conventional hydrocarbon resources (crude oil), unconventional hydrocarbon resources (oil sands or oil shale), and biological feedstocks through a variety of biochemical or thermo chemical processes, or by converting natural gas or coal to liquids.

Complexes of niobium and tantalum containing metal-metal bonds  

SciTech Connect (OSTI)

A new entry into the area of low valent niobium and tantalum complexes containing metal-metal bonds is described. M/sub 2/X/sub 6/ (..mu..-THT)(THF)/sub 2/ complexes, where M = Nb or Ta, X = Cl or Br and THT - tetrahydrothiophene, are conveniently synthesized via the reaction of M/sub 2/M/sub 6/(THT)/sub 3/ with THF (THF = tetrahydrofuran). Unlike M/sub 2/X/sub 6/(THT)/sub 3/, M/sub 2/X/sub 6/(..mu..-THT)(THF)/sub 2/ can be easily reduced by sodium amalgam. In THF and in the presence of THT, complexes of the type M/sub 2/X/sub 6/(..mu..-THT)/sub 3//sup 2 -/ form. Salts of these compounds can also be synthesized directly from the metal pentahalides in a two step, one pot reaction in which M/sub 2/X/sub 6/(THT)/sub 3/ is an intermediate. The M/sub 2/X/sub 6/(..mu..-THT)/sub 3//sup 2 -/ complexes have a face-sharing bioctahedral structure with metal-metal triple bonds, the first reported for niobium or tantalum. These compounds are relatively inert, but (Nb/sub 2/Cl/sub 6/(..mu..-THT)/sub 3//sup 2 -/ does reach with pyridine and with a solution of acetic acid/acetic anhydride. These reactions and those of some of the sodium salts are described. In general, trinuclear complexes of niobium and tantalum are rare, and this type of discrete trinuclear complex, which contains one capping, three bridging and nine terminal ligands, has been seen only once before for the group 5 metals, although many examples of similar group 6 metal complexes are known. Full details of the synthesis and characterization of these complexes are described and an interpretation of their electronic structures is given.

Transition metal oxides deposited on rhodium and platinum: Surface chemistry and catalysis  

SciTech Connect (OSTI)

The surface chemistry and catalytic reactivity of transition metal oxides deposited on Rh and Pt substrates has been examined in order to establish the role of oxide-metal interactions in influencing catalytic activity. The oxides investigated included titanium oxide (TiOx), vanadium oxide (VOx), iron oxide (FeOx), zirconium oxide (ZrOx), niobium oxide (NbOx), tantalum oxide (TaOx), and tungsten oxide (WOx). The techniques used to characterize the sample included AES, XPS, LEED, TPD, ISS, and STM. After characterization of the surface in UHV, the sample was enclosed in an atmospheric reaction cell to measure the influence of the oxide deposits on the catalytic activity of the pure metal for CO and CO{sub 2} hydrogenation. The oxide deposits were found to strongly enhance the reactivity of the Rh foil. The rates of methane formation were promoted by up to 15 fold with the maximum in rate enhancement occurring at oxide coverages of approximately 0.5 ML. TiOx TaOx, and NbOx were the most effective promoters and were stable in the highest oxidation states during both reactions (compared to VOx, WOx, and FeOx). The trend in promoter effectiveness was attributed to the direct relationship between oxidation state and Lewis acidity. Bonding at the metal oxide/metal interface between the oxygen end of adsorbed CO and the Lewis acidic oxide was postulated to facilitate C-O bond dissociation and subsequent hydrogenation. 192 refs.

Humic Acid Metal Cation Interaction Studied by Spectromicroscopy Techniques in Combination with Quantum Chemical Calculations  

SciTech Connect (OSTI)

Humic acids (HA) have a high binding capacity towards traces of toxic metal cations, thus affecting their transport in aquatic systems. Eu(III)-HA aggregates are studied by synchrotron-based scanning transmission X-ray microscopy (STXM) at the carbon K-edge and laser scanning luminescence microscopy (LSLM) at the {sup 5}D{sub 0} {yields} {sup 7}F{sub 1,2} fluorescence emission lines. Both methods provide the necessary spatial resolution in the sub-micrometre range to resolve characteristic aggregate morphologies: optically dense zones embedded in a matrix of less dense material in STXM images correspond to areas with increased Eu(III) luminescence yield in the LSLM micrographs. In the C 1s-NEXAFS of metal-loaded polyacrylic acid (PAA), used as a HA model compound, a distinct complexation effect is identified. This effect is similar to trends observed in the dense fraction of HA/metal cation aggregates. The strongest complexation effect is observed for the Zr(IV)-HA/PAA system. This effect is confirmed by quantum chemical calculations performed at the ab initio level for model complexes with different metal centres and complex geometries. Without the high spatial resolution of STXM and LSLM and without the combination of molecular modelling with experimental results, the different zones indicating a 'pseudo'-phase separation into strong complexing domains and weaker complexing domains of HA would never have been identified. This type of strategy can be used to study metal interaction with other organic material.

Modal analysis and coupling in metal-insulator-metal waveguides  

Science Journals Connector (OSTI)

This paper shows how to analyze plasmonic metal-insulator-metal waveguides using the full modal structure of these guides. The analysis applies to all frequencies, particularly including the near infrared and visible spectrum, and to a wide range of sizes, including nanometallic structures. We use the approach here specifically to analyze waveguide junctions. We show that the full modal structure of the metal-insulator-metal (MIM) waveguideswhich consists of real and complex discrete eigenvalue spectra, as well as the continuous spectrumforms a complete basis set. We provide the derivation of these modes using the techniques developed for Sturm-Liouville and generalized eigenvalue equations. We demonstrate the need to include all parts of the spectrum to have a complete set of basis vectors to describe scattering within MIM waveguides with the mode-matching technique. We numerically compare the mode-matching formulation with finite-difference frequency-domain analysis and find very good agreement between the two for modal scattering at symmetric MIM waveguide junctions. We touch upon the similarities between the underlying mathematical structure of the MIM waveguide and the PT symmetric quantum-mechanical pseudo-Hermitian Hamiltonians. The rich set of modes that the MIM waveguide supports forms a canonical example against which other more complicated geometries can be compared. Our work here encompasses the microwave results but extends also to waveguides with real metals even at infrared and optical frequencies.

Electron Spin Resonance in Metals and Metal-Ammonia Solutions  

Science Journals Connector (OSTI)

Electron spin resonance measurements have been made at 300 Mc/sec on frozen metal ammonia solutions, liquid metal ammonia solutions, and liquid metals. The experiments on frozen solutions have shown that the metal is precipitated out in small particles. Nuclear resonance experiments have corroborated this finding. The frozen solutions are used as a convenient source of small particles, and observations have been made of relaxation times in Na, Li, K, and Cs. Resonances in the liquid ammonia solutions of Li, Na, K, Rb, Cs, and Ca, and also in a solution of Li in methylamine were observed. The data are consistent with the theoretical model of Kraus, Ogg, and Kaplan and Kittel. Bulk metal resonances were observed to temperatures above the melting points on lithium and sodium. The results for sodium corroborate the Elliott theory of relaxation, and the lithium results indicate resistivity-dependent relaxation time. No resonance was observed in bulk K, Rb, and Cs carried to temperatures above their melting points.

Alkali-metal-atom chemisorption onto a metal surface  

Science Journals Connector (OSTI)

Recent theoretical and experimental work implies that an alkali-metal atom chemisorbed onto a metal surface can be viewed within a dressed-atom picture, i.e., as an atom whose wave functions are perturbed due to its interaction with the surrounding host lattice. This picture is similar to that used for a noble-gas atom physisorbed onto a metal surface. Such an approach utilizes the calculational method of the coupledHartree-Fock theory, and it is applied in the present work to the chemisorption of a potassium atom onto a semi-infinite Na(001) substrate. Results for the Hartree-Fock ground state of the chemisorbed K atom, its induced dipole moment, and induced splitting of its p-orbital states are calculated at various substrate-adatom separations. It has been found that the induced dipole moment exhibits a maximum in its absolute value as the metal-adatom separation changes; most of the contribution to the dipole moment is due to the 3s- and 4s-electron states, while the pz states have been found to be counterpolarized, i.e., they polarize toward the vacuum side. On the other hand, the calculated dipole moments of the adatom were found to be too small to account for the observed work-function changes during alkali-metal chemisorption on a mteal surface.

The scarce of coking coal resources in China results in its short supply. By establishing a grey linear regression composition model, this paper has greatly improved the inadequacy of grey system prediction model and regression analysis method in trend prediction and finished the prediction of demand trends of coking coal in China with this model. As result of the prediction, it is estimated that in the next decade, the demand for coking coal in China will experience a growth trend; China's demand for coking coal will reach more than 1.535 billion tons by 2015, reach the maximum of 1.639 billion tons by 2020 and drop in 2025.

Covalent Hydration Reactions in Model Monomeric Ru 2,2'-Bipyridine Complexes: Thermodynamic Favorability as a Function of Metal Oxidation and Overall Spin States  

SciTech Connect (OSTI)

Density functional theory (DFT) has been used to investigate the plausibility of water addition to the simple mononuclear ruthenium complexes, [(NH{sub 3}){sub 3}(bpy)Ru=O]{sup 2+}/{sup 3+} and [(NH{sub 3}){sub 3}(bpy)RuOH]{sup 3+}, in which the OH fragment adds to the 2,2{prime}-bipyridine (bpy) ligand. Activation of bpy toward water addition has frequently been postulated within the literature, although there exists little definitive experimental evidence for this type of 'covalent hydration'. In this study, we examine the energetic dependence of the reaction upon metal oxidation state, overall spin state of the complex, as well as selectivity for various positions on the bipyridine ring. The thermodynamic favorability is found to be highly dependent upon all three parameters, with free energies of reaction that span favorable and unfavorable regimes. Aqueous addition to [(NH{sub 3}){sub 3}(bpy)Ru=O]{sup 3+} was found to be highly favorable for the S = 1/2 state, while reduction of the formal oxidation state on the metal center makes the reaction highly unfavorable. Examination of both facial and meridional isomers reveals that when bipyridine occupies the position trans to the ruthenyl oxo atom, reactivity toward OH addition decreases and the site preferences are altered. The electronic structure and spectroscopic signatures (EPR parameters and simulated spectra) have been determined to aid in recognition of 'covalent hydration' in experimental systems. EPR parameters are found to uniquely characterize the position of the OH addition to the bpy as well as the overall spin state of the system.

Electronic Structure of Noble-Metal-Noble-Metal Alloys  

Science Journals Connector (OSTI)

We describe optical studies of dilute noble-metal-noble-metal alloys. A differential technique compared the reflectance of the alloy with the reflectance of the pure metal and measured a quantity proportional to just the difference in reflectance. The method was particularly sensitive to small changes in reflectances and could be used to study very dilute alloys-the alloys here were between 110- and 3-at.% impurity concentration. The measurements indicated that the noble alloys are of two types. In copper-gold and silver-gold alloys the electron energy bands shift smoothly as the concentration varies. The rates and directions of shifts are determined not only by differences in the host and impurity potentials, but also by the changes in lattice constant, and we emphasize the importance of the latter. In contrast, in copper-silver alloys separate host and impurity d bands are formed.

Electron transport through a metal-molecule-metal junction  

Science Journals Connector (OSTI)

Molecules of bisthiolterthiophene have been adsorbed on the two facing gold electrodes of a mechanically controllable break junction in order to form metal-molecule(s)-metal junctions. Current-voltage (I-V) characteristics have been recorded at room temperature. Zero bias conductances were measured in the 10100 nS range and different kinds of nonlinear I-V curves with steplike features were reproducibly obtained. Switching between different kinds of I-V curves could be induced by varying the distance between the two metallic electrodes. The experimental results are discussed within the framework of tunneling transport models explicitly taking into account the discrete nature of the electronic spectrum of the molecule.

Trends in water quality variability for coalbed methane produced water  

Science Journals Connector (OSTI)

Abstract Energy production from unconventional natural gas resources, such as coalbed methane, has the potential to generate significant water quantities for use in water-stressed areas to augment existing water supplies. Coalbed methane (CBM) produced water is generated from shallower formations than traditional oil and gas resources where water quality may be influenced by fresh water supplies in the area. Variability in produced water quality between wells and across geologic basins must be characterized in order to categorize water types appropriate for beneficial use. Principal component analysis (PCA) was applied to a composite geochemical database to identify indicators of variability in water composition and quality. Component analysis revealed that water quality indicators of variability were related to: (i) aquifer recharge that dilutes constituent concentrations (37%), (ii) dissolution of soluble aquifer minerals such as sodium and exchange of calcium and magnesium (13.8%), and (iii) coal depositional environment influence on chloride and trace metal fractions (14% of variability). Ternary relationships between NaClHCO3 and NaCaMg correlate to marine influence in the coal depositional environment and well proximity to recharge, respectively. Relationships identified in this study highlight water quality compositions with opportunities for beneficial use.

Cold nuclear fusion in metallic hydrogen and normal metals  

Science Journals Connector (OSTI)

The rate of nuclear fusion from tunneling in very dense metallic hydrogen in the core of Jupiter is calculated to be 10-50 per hydrogen-deuterium pair per second. It is estimated that the width of the fusion barrier for deuterium in palladium or a similar metal must be reduced to, of order, 0.1 A? for the fusion rate to be 10-25 per deuterium per second.

Electron-electron scattering in metal-insulator-metal sandwiches  

Science Journals Connector (OSTI)

We have studied weak localization and electron-electron interaction effects in samples consisting of two thin metal films separated by an insulating layer of SiO. When the SiO thickness was less than about 200 , the electron-electron scattering rate was enhanced with respect to that found in isolated, i.e., well-separated, films. This suggests that in the sandwich structures, electrons in one metal film are able to communicate with, i.e., scatter from, electrons in the other film across distances of order 200 , and that this process enhances the phase-breaking rate.

Semiconductor-To-Metal Transitions in Transition-Metal Compounds  

Science Journals Connector (OSTI)

The theory presented in a previous paper is applied to the transition-metal compounds which are known to exhibit semiconductor-to-metal transitions. In particular, the predictions of the theory are compared with the experimental results of Feinleib and Paul on V2O3. Very good agreement is obtained for the magnitude of the energy gap and for its pressure and stress coefficients. The theory appears to be consistent with the available data on the other oxides of vanadium and titanium as well. Band models for all of these compounds are suggested. The effects of spin-disorder scattering and broadening, polaron formation, and non-stoichiometry are considered quantitatively.

Achieving perpendicular anisotropy in half-metallic Heusler alloys for spin device applications  

SciTech Connect (OSTI)

Various full Heusler alloys are interfaced with MgO and the magnetic properties of the Heusler-MgO junctions are studied. Next to MgO, the cubic Heusler system distorts to a tetragonal one, thereby inducing an anisotropy. The half-metallicity and nature of anisotropy (in-plane or perpendicular) in the Heusler-MgO system is governed mostly by the interface Heusler layers. There is a trend that Mn-O bonding near the MgO-Heusler junction results in perpendicular anisotropy. The ability to remain half-metallic and have perpendicular anisotropy makes some of these alloys potential candidates as free-layers in Spin Transfer Torque Random Access Memory (STT-RAM) devices, particularly, Cr{sub 2}MnAs-MgO system with MnAs interface layers and Co{sub 2}MnSi-MgO system with Mn{sub 2} interface layers.

Approximating Metal-Insulator Transitions  

E-Print Network [OSTI]

We consider quantum wave propagation in one-dimensional quasiperiodic lattices. We propose an iterative construction of quasiperiodic potentials from sequences of potentials with increasing spatial period. At each finite iteration step the eigenstates reflect the properties of the limiting quasiperiodic potential properties up to a controlled maximum system size. We then observe approximate metal-insulator transitions (MIT) at the finite iteration steps. We also report evidence on mobility edges which are at variance to the celebrated Aubry-Andre model. The dynamics near the MIT shows a critical slowing down of the ballistic group velocity in the metallic phase similar to the divergence of the localization length in the insulating phase.

Magnetism of nanosized metallic particles  

Science Journals Connector (OSTI)

The magnetism of a small cluster of magnetic atoms at finite temperatures is numerically investigated. The evolution of the system towards thermal equilibrium is studied, and the possibility of occurrence of vortexlike excitations in the arrangement of the magnetic moments within the cluster is pointed out. The magnetization curve as a function of temperature, of a small magnetic particle, suggests that magnetic clusters in granular metals are not saturated even at room temperature. The relevance of the present results to the understanding of the magnetic behavior of granular metals is discussed.

Atomic and electronic structure of simple metal/graphene and complex metal/graphene/metal interfaces  

Science Journals Connector (OSTI)

Structural, electronic, and magnetic properties of simple interfaces (graphene on top of a metallic substrate) and complex interfaces (a single metallic adlayer on a simple graphene/metal system, either on top or between the graphene and metallic substrate) have been studied using density functional theory. Two types of simple interface with strong (Ni/graphene) and weak (Cu/graphene) bonding were considered. In addition to binding energies and interface distances, which are used to quantify the strength of graphene-substrate interactions, the bonding in simple and complex interfaces was analyzed using charge density distributions and bond orders. Substantial enhancement of the metallic substrate/graphene binding was observed in complex interfaces, consisting of a Ni monolayer on top of a simple {Ni or Cu}/graphene interface. The increase of substrate-graphene bonding in such complex interfaces is accompanied by weakening of in-plane C-C bonds in graphene, as quantified by the bond orders. A weak ferrimagnetism in graphene, i.e., unequal magnetic moments ?0.04?B and +0.06?B on the C atoms, is induced by a ferromagnetic Ni substrate. The strength of graphene-substrate interactions is also reflected in simulated scanning tunneling microscopy images.

Metal-insulator transition in dilute alkali-metal systems  

Science Journals Connector (OSTI)

The metal-insulator transition is studied for dilute systems of alkali metals. Using a spin-split self-consistent band-structure approach, we find the transition density, a strikingly enhanced magnetic susceptibility, and the electron effective mass. The critical density nc is found to be given by the simple relation rsc=r0+2.8. Here rsc=[3(4?nc)]13 and r0 is the model potential radius which is roughly the radius of the neutral atom. The Mott criterion of nc13aB?0.25 (where aB is the appropriate Bohr orbit) is found to be inadequate for describing these systems. The predicted effective mass and magnetic susceptibility enhancements are largest for Li and become systematically smaller for the heavier alkalis. We compare our results for the transition density with two sets of experiments, namely the gas-liquid critical density and the metal-insulator transition for codeposited thick films of alkali-metal and rare-gas atoms. Good agreement is found in both cases.

Metal-on-Metal Bonding and Rebonding Revisited

Density-functional calculations for a wide variety of metals show that, contrary to rebonding theory, ad-dimers do not have notably longer surface bonds than adatoms, do not reside farther above the surface, and do not meet the rebonding arguments for augmented mobility. Rebonding contributes to destabilize ad-dimers, but does not explain inherently weak ad-dimer bonds.

Trend Motif: A Graph Mining Approach for Analysis of Dynamic Complex Networks  

SciTech Connect (OSTI)

Complex networks have been used successfully in scientific disciplines ranging from sociology to microbiology to describe systems of interacting units. Until recently, studies of complex networks have mainly focused on their network topology. However, in many real world applications, the edges and vertices have associated attributes that are frequently represented as vertex or edge weights. Furthermore, these weights are often not static, instead changing with time and forming a time series. Hence, to fully understand the dynamics of the complex network, we have to consider both network topology and related time series data. In this work, we propose a motif mining approach to identify trend motifs for such purposes. Simply stated, a trend motif describes a recurring subgraph where each of its vertices or edges displays similar dynamics over a userdefined period. Given this, each trend motif occurrence can help reveal significant events in a complex system; frequent trend motifs may aid in uncovering dynamic rules of change for the system, and the distribution of trend motifs may characterize the global dynamics of the system. Here, we have developed efficient mining algorithms to extract trend motifs. Our experimental validation using three disparate empirical datasets, ranging from the stock market, world trade, to a protein interaction network, has demonstrated the efficiency and effectiveness of our approach.

Bis(pentamethylcyclopentadienyl) ytterbium: Electron-transfer reactions with organotransition metal complexes  

SciTech Connect (OSTI)

The divalent lanthanide complex, (Me{sub 5}C{sub 5}){sub 2}Yb, reacts with methylcopper to produce the base-free, ytterbium-methyl complex, (Me{sub 5}C{sub 5}){sub 2}YbMe. This product forms a asymmetric, methyl-bridged dimer in the solid state. The bulky alkyl complex, (Me{sub 5}C{sub 5}){sub 2}YbCH(SiMe{sub 3}){sub 2}, displays similar chemistry to (Me{sub 5}C{sub 5}){sub 2}YbMe, but at a reduced reaction rate due to the limited accessibility of the metal in (Me{sub 5}C{sub 5}){sub 2}YbCH(SiMe{sub 3}){sub 2}. Copper and silver halide salts react with (Me{sub 5}C{sub 5}){sub 2}V to produce the trivalent halide derivatives, (Me{sub 5}C{sub 5}){sub 2}VX (X + F, Cl, Br, I). The chloride complex, (Me{sub 5}C{sub 5}){sub 2}VCl, reacts with lithium reagents to form the phenyl and borohydride species. Nitrous oxide transfers an oxygen atom to (Me{sub 5}C{sub 5}){sub 2}V producing the vanadium-oxo complex, (Me{sub 5}Ce{sub 5}){sub 2}VO. The trivalent titanium species, (Me{sub 5}C{sub 5}){sub 2}TiX (X = Cl, Br, Me, BH{sub 4}), form bimetallic coordination complexes with (Me{sub 5}C{sub 5}){sub 2}Yb. The magnetic behavior of the products indicates that electron transfer has not occurred. The solid state structures of the chloride and bromide complexes show unusual bend angles for the halide bridges between ytterbium and titanium. A model based on frontier orbital theory has been proposed to account for the bending behavior in these species. The bimetallic methyl complex contains a linear methyl bridge between ytterbium and titanium.

Two New Tests of the Metallicity Sensitivity of the Cepheid Period-luminosity Relation (the Leavitt Law)  

Science Journals Connector (OSTI)

We undertake a new test of the metallicity sensitivity of the Leavitt Law for classical Cepheids. We derive an empirical calibration of the apparent luminosities of Cepheids as measured from the optical through the mid-infrared (0.45-8.0 ?m) as a function of spectroscopic [Fe/H] abundances of individual Cepheids in the Large Magellanic Cloud (LMC) from Romaniello etal. The cumulative trend over the entire wavelength range shows a nearly monotonic behavior. The sense of the trend is consistent with differential line blanketing in the optical, leading to stars of high metallicity being fainter in the optical. This is followed by a reversal in the trend at longer wavelengths, with the crossover occurring near the K band at about 2.2 ?m, consistent with a subsequent redistribution of energy resulting in a mild brightening of Cepheids (with increased metallicity) at mid-infrared wavelengths. This conclusion agrees with that of Romaniello etal. based on a differential comparison of the mean V- and K-band Leavitt Laws for the Galaxy, Small Magellanic Cloud, and LMC, but is opposite in sign to most other empirical tests of the sensitivity of Cepheid distances to mean [O/H] HII region abundances. We also search for a correlation of Cepheid host-galaxy metallicity with deviations of the galaxy's Cepheid distance from that predicted from a pure Hubble flow. Based on Cepheid distances to 26 nearby galaxies in the local flow, only a very weak signal is detected giving ?? o = 0.17( 0.31)([O/H] 8.80) 0.21( 0.10). This is in agreement with previous determinations, but statistically inconclusive.

Heavy metals in Antarctic organisms  

SciTech Connect (OSTI)

To evaluate levels of essential (zinc and copper) and non-essential (mercury and cadmium) heavy metals, 34 species of organisms from different areas close to the Antarctic Peninsula were analysed. These included algae, filter-feeders, omnivorous invertebrates and vertebrates. Mercury was not detected, while cadmium was found in the majority of organisms analysed (detection limit was 0.05 ppm for both metals). The highest cadmium concentration was observed in the starfish Odontaster validus. Anthozoans, sipunculids and nudibranchs showed maximum levels of zinc, while the highest copper level was found in the gastropod Trophon brevispira. Mercury and cadmium levels in fishes were below the detection limit. Concentrations of essential and non-essential metals in birds were highest in liver followed by muscle and eggs. Cadmium and mercury levels in muscle of southern elephant seals were above the detection limit, whereas in Antarctic fur seals they were below it. The objective of the study was to gather baseline information for metals in Antarctic Ocean biota that may be needed to detect, measure and monitor future environmental changes. 46 refs., 7 figs., 8 tabs.

Magnetism in amorphous transition metals  

Science Journals Connector (OSTI)

Overall features of magnetism in amorphous transition metals have been investigated on the basis of a finite-temperature theory of the local-environment effect. It is shown that the simple ferromagnetism of Fe, Co, and Ni is drastically changed by structural disorder; amorphous transition metals form spin glasses (SGs) for compositions near amorphous Fe (6.7?N?7.35), ferromagnets for compositions near amorphous Co (7.35?N?9.0), and paramagnetisms for compositions near amorphous Ni (9.0?N?10.0) where N is the number of d electrons. The SG is accompanied by formation of local ferromagnetic clusters for N?7.2, and shows reentrant behavior at the ferromagnetic boundary N?7.35. The ferromagnetism in amorphous transition metals is shown to be well explained by the main-peak position in the noninteracting densities of states. It is found that structural disorder enhances the Curie temperatures (TC) in the range 7.9?N?8.5 as compared with bcc and fcc structures. These results explain recent experimental data for the SG in Fe-rich amorphous alloys and the high TC in amorphous Co-Y alloys, but they are quite different from the early picture obtained for amorphous transition-metalmetalloid alloys.

Electronic properties of a simple metal-metal interface  

Science Journals Connector (OSTI)

The properties of metal-metal interfaces are of interest in many metallurgical applications. These include grain boundaries, crack growth, friction, and bimetallic adhesion. The present work is a study of the electronic properties of a simple bimetallic junction. The methods employed to investigate the interface are the Green's-function technique and the phase-shift method. We calculate the Green's function of a simple junction within the tight-binding approximation. The conditions for the occurrence of bound states are deduced from the poles of the Green's function. Using the phase-shift method we derive an expression for the change in density of states due to the creation of the interface. From this expression we derive the corresponding single-particle contribution to the interface energy and the interface specific heat.

Metal-nonmetal transition in metal-ammonia solutions  

Science Journals Connector (OSTI)

In this paper we present a coherent physical picture of the metal-nonmetal transition in metal-ammonia solutions in the intermediate concentration range. We propose that in Li-NH3 and Na-NH3 solutions the metallic propagation regime is separated from a nonmetallic regime by a microscopically inhomogeneous regime in which the concentration fluctuates locally about either of two well-defined values M0 and M1, M0>M1, the local concentration remaining near M0 or M1 over radii approximately equal to the Debye short correlation length b for concentration fluctuations. Provided that the concentration-fluctuation decay length is much smaller than b, we can define a percolation problem in which a volume fraction C of the material is occupied by metallic regions of concentration M0, the remainder containing the low concentration M1 of dissociated electron-cation complexes. M0 and M1 constitute the upper and the lower bounds of the inhomogeneous regime, respectively, while C exhibits a linear dependence on M. This physical picture is borne out by concentration-fluctuation determinations based on chemical-potential measurements in Li and Na solutions and by small-angle x-ray and neutron scattering in Li solutions. Assuming that the phase-coherence length of the conduction electrons is shorter than b and having demonstrated that tunneling corrections are negligible, we can define local electronic structure and transport properties. The limits of the inhomogeneous regime were determined from a combination of concentration-fluctuation measurements, electrical conductivity, Hall effect, and paramagnetic susceptibility data to be M0=9 mole percent metal (MPM) and M1=2(13) MPM, which yield the C scale, C=[M-2(13)]6(23), for both Li-NH3 at 223K and for Na-NH3 at 240K. We have also established the consistency of our picture with the available magnetic data for Na solutions. An analysis of the electronic and the thermal transport properties was carried out in terms of an effective-medium theory, modified to account for scattering from the boundaries of the metallic clusters. For low values of the conductivity ratio (? 10-3) between the nonmetallic and the metallic regions the modified effective-medium theory is valid for C>0.4. In an attempt to mimic the features of continuous percolation, we have carried out numerical simulations of the conductivity in a simple cubic lattice incorporating correlation between metallic bonds. An excellent fit of the experimental conductivity data for Li and Na with the results of the numerical simulations has been obtained over a three order of magnitude variation of the conductivity throughout the entire inhomogeneous regime. A small systematic negative deviation of the conductivity from the predictions of the effective-medium theory for C>0.4 can be properly accounted for in terms of boundary scattering corrections resulting in b?15 for Li at 223K and b?32 for Na at 240K. The overall agreement of the experimental Hall effect, Hall mobility, thermalconductivity, and thermoelectric-power data with the effective-medium theory is good. The proposed inhomogeneous regime in Li and Na solutions resembles a macroscopic mixed phase at a concentration inside a coexistence curve but with mixing on a microscopic scale. The concentration fluctuations in the inhomogeneous state have nothing to do with critical fluctuations; nevertheless, this state seems to be closely associated with the occurrence of a phase separation.

Growth dynamics at a metal-metal interface  

Science Journals Connector (OSTI)

A determination of the sticking coefficient of sputter-deposited metal films on freshly deposited metal surfaces is described in detail. The systems investigated were Mo deposited on Ta and Ta on Mo. Also described is a detailed determination of the structure of Mo-Ta interfaces using Rutherford backscattering spectrometry and a combination of x-ray diffraction techniques. Within a few angstroms of each interface we find that the lattice is stretched in the growth direction and has an excess of defects relative to the bulk lattice. We also find that Mo/Ta superlattices fabricated with wavelengths in the range 20 to 120 A? exhibit structural coherence extending over a number of superlattice layers.

Metal-dielectric-metal surface plasmon-polariton resonators  

Science Journals Connector (OSTI)

A theoretical study of standing-wave resonances of surface plasmon polaritons (SPPs) in finite-length metal-dielectric-metal cavities is presented. A Fabry-Prot model is constructed to describe the cavity resonances, and the associated optical parameters are calculated analytically. One key parameter is the phase acquired by resonating SPPs upon reflection from cavity end faces. This phase pickup is associated with the near-field energy storage at these end faces, and the imaginary part of the reflection coefficient is shown to be approximately proportional to the stored energy. Using the Fabry-Prot model, we also calculate the transmission cross section, peak position, as well as the Q factor of the cavity, and we find good agreement with full-field numerical simulations for a wide range of wavelengths and device dimensions.

Theory of the alkali-metal chemisorption on metal surfaces  

Science Journals Connector (OSTI)

The electronic structure of the alkali-metal adatom on metal surfaces is studied by a first-principles method as a function of adatom coverage (?). We employ jellium as a high-density metal substrate to make a continuous change of ? possible. Although the characteristic variation of the work function with ? is reproduced well by the present calculation, its mechanism is different from a widely accepted mechanism in which the adatom electronic structure is assumed to change from ionic to neutral with increasing ? by the depolarization shift. The charge redistribution ??(r,?) that lowers the work function deviates far from the point-charge-transfer model, and the electrostatic potential change at adatom sites due to ??(r,?) depends very little on ?. Accordingly, the adatom valence density of states shows no downward shift with increasing ?. The adatom region is essentially neutral, even at low ?. The bonding-antibonding boundary in the bond-order density of the adatom-substrate bond coincides well with the Fermi level at low ?, indicating a formation of a metallic bond by the maximum use of bonding states even at low ?. The close similarity between the calculated bond-order and dipole densities as a function of the one-electron energy implies that the adatom polarization due to the hybridization of adatom and substrate orbitals plays an important role for the adatom dipole and its ? dependence even at low ?. The decrease of the adatom dipole is explained by a weakening of the adatom-substrate bonding as well as a significant decrease in the dipole matrix elements with increasing ?.

Methodological trends in the design of recent microenvironmental studies of personal CO exposure  

Science Journals Connector (OSTI)

This paper describes the designs of three recent microenvironmental studies of personal exposure to carbon monoxide (CO) from motor vehicle exhaust. These studies were conducted sequentially, first in four California cities (Los Angeles, Mountain View, Palo Alto, and San Francisco), then in Honolulu, and, most recently, in metropolitan Washington, D.C. Though study purposes differed, each study faced common methodological issues related to personal exposure monitors (PEMs), quality assurance and data collection procedures, and the selection of microenvironments for study. Two major objectives of the California cities study were to determine the CO concentrations typically found in commercial settings and to define and classify microenvironments applicable to such settings: The Honolulu study measured merchant exposure to CO in shopping centers attached to semienclosed parking garages during business hours and commuter exposure to CO in vehicles (passenger cars and buses) on congested roadways during peak periods. The intent of the Washington study was to develop a model of commuter exposure to motor vehicle exhaust using CO as an indicator pollutant. Certain trends are discernible from reviewing the three studies. There are clearly trends in PEM development that have expanded instrument capabilities and automated data collection and storage. There are also trends towards more rigorous quality assurance procedures and more standardized protocols for collecting exposure data. Further, one can see a trend towards more elaborate indicators for identifying microenvironments for study. Finally, there is a trend towards using personal monitors in public policy review and evaluation.

Synthesis of transition metal carbonitrides  

DOE Patents [OSTI]

Transition metal carbonitrides (in particular, titanium carbonitride, TiC.sub.0.5 N.sub.0.5) are synthesized by a self-propagating reaction between the metal (e.g., titanium) and carbon in a nitrogen atmosphere. Complete conversion to the carbonitride phase is achieved with the addition of TiN as diluent and with a nitrogen pressure .gtoreq.0.6 MPa. Thermodynamic phase-stability calculations and experimental characterizations of quenched samples provided revealed that the mechanism of formation of the carbonitride is a two-step process. The first step involves the formation of the nonstoichiometric carbide, TiC.sub.0.5, and is followed by the formation of the product by the incorporation of nitrogen in the defect-structure carbide.

Magnons in ferromagnetic metallic manganites  

SciTech Connect (OSTI)

Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest not only because they are a testing ground for the classical double-exchange interaction mechanism for the colossal magnetoresistance, but also because they exhibit an extraordinary arena of emergent phenomena. These emergent phenomena are related to the complexity associated with strong interplay between charge, spin, orbital, and lattice. In this review, we focus on the use of inelastic neutron scattering to study the spin dynamics, mainly the magnon excitations in this class of FM metallic materials. In particular, we discuss the unusual magnon softening and damping near the Brillouin zone boundary in relatively narrow-band compounds with strong Jahn CTeller lattice distortion and charge Corbital correlations. The anomalous behaviours of magnons in these compounds indicate the likelihood of cooperative excitations involving spin and lattice as well as orbital degrees of freedom.

Liquid metal Flow Meter - Final Report  

SciTech Connect (OSTI)

Measuring the flow of liquid metal presents serious challenges. Current commercially-available flow meters use ultrasonic, electromagnetic, and other technologies to measure flow, but are inadequate for liquid metal flow measurement because of the high temperatures required by most liquid metals. As a result of the reactivity and high temperatures of most liquid metals, corrosion and leakage become very serious safety concerns. The purpose of this project is to develop a flow meter for Lockheed Martin that measures the flow rate of molten metal in a conduit.

Metal resistance sequences and transgenic plants  

SciTech Connect (OSTI)

The present invention provides nucleic acid sequences encoding a metal ion resistance protein, which are expressible in plant cells. The metal resistance protein provides for the enzymatic reduction of metal ions including but not limited to divalent Cu, divalent mercury, trivalent gold, divalent cadmium, lead ions and monovalent silver ions. Transgenic plants which express these coding sequences exhibit increased resistance to metal ions in the environment as compared with plants which have not been so genetically modified. Transgenic plants with improved resistance to organometals including alkylmercury compounds, among others, are provided by the further inclusion of plant-expressible organometal lyase coding sequences, as specifically exemplified by the plant-expressible merB coding sequence. Furthermore, these transgenic plants which have been genetically modified to express the metal resistance coding sequences of the present invention can participate in the bioremediation of metal contamination via the enzymatic reduction of metal ions. Transgenic plants resistant to organometals can further mediate remediation of organic metal compounds, for example, alkylmetal compounds including but not limited to methyl mercury, methyl lead compounds, methyl cadmium and methyl arsenic compounds, in the environment by causing the freeing of mercuric or other metal ions and the reduction of the ionic mercury or other metal ions to the less toxic elemental mercury or other metals.

Modeling Ethanol Decomposition on Transition Metals: A Combined Application of Scaling and Brnsted-Evans-Polanyi Relations  

SciTech Connect (OSTI)

Applying density functional theory (DFT) calculations to the rational design of catalysts for complex reaction networks has been an ongoing challenge, primarily because of the high computational cost of these calculations. Certain correlations can be used to reduce the number and complexity of DFT calculations necessary to describe trends in activity and selectivity across metal and alloy surfaces, thus extending the reach of DFT to more complex systems. In this work, the well-known family of Brnsted-Evans-Polanyi (BEP) correlations, connecting minima with maxima in the potential energy surface of elementary steps, in tandem with a scaling relation, connecting binding energies of complex adsorbates with those of simpler ones (e.g., C, O), is used to develop a potential-energy surface for ethanol decomposition on 10 transition metal surfaces. Using a simple kinetic model, the selectivity and activity on a subset of these surfaces are calculated. Experiments on supported catalysts verify that this simple model is reasonably accurate in describing reactivity trends across metals, suggesting that the combination of BEP and scaling relations may substantially reduce the cost of DFT calculations required for identifying reactivity descriptors of more complex reactions.
