Evaluation of electron mobility in InSb quantum wells by means of percentage-impact  

SciTech Connect

In order to quantitatively analyze the contribution of each scattering factor toward the total carrier mobility, we use a new convenient figure-of-merit, named a percentage impact. The mobility limit due to a scattering factor, which is widely used to summarize a scattering analysis, has its own advantage. However, a mobility limit is not quite appropriate for the above purpose. A comprehensive understanding of the difference in contribution among many scattering factors toward the total carrier mobility can be obtained by evaluating percentage impacts of scattering factors, which can be straightforwardly calculated from their mobility limits and the total mobility. Our percentage impact analysis shows that threading dislocation is one of the dominant scattering factors for the electron transport in InSb quantum wells at room temperature.

Formulation, Pretreatment, and Densification Options to Improve Biomass Specifications for Co-Firing High Percentages with Coal  

SciTech Connect

There is a growing interest internationally to use more biomass for power generation, given the potential for significant environmental benefits and long-term fuel sustainability. However, the use of biomass alone for power generation is subject to serious challenges, such as feedstock supply reliability, quality, and stability, as well as comparative cost, except in situations in which biomass is locally sourced. In most countries, only a limited biomass supply infrastructure exists. Alternatively, co-firing biomass alongwith coal offers several advantages; these include reducing challenges related to biomass quality, buffering the system against insufficient feedstock quantity, and mitigating the costs of adapting existing coal power plants to feed biomass exclusively. There are some technical constraints, such as low heating values, low bulk density, and grindability or size-reduction challenges, as well as higher moisture, volatiles, and ash content, which limit the co-firing ratios in direct and indirect co-firing. To achieve successful co-firing of biomass with coal, biomass feedstock specifications must be established to direct pretreatment options in order to modify biomass materials into a format that is more compatible with coal co-firing. The impacts on particle transport systems, flame stability, pollutant formation, and boiler-tube fouling/corrosion must also be minimized by setting feedstock specifications, which may include developing new feedstock composition by formulation or blending. Some of the issues, like feeding, co-milling, and fouling, can be overcome by pretreatment methods including washing/leaching, steam explosion, hydrothermal carbonization, and torrefaction, and densification methods such as pelletizing and briquetting. Integrating formulation, pretreatment, and densification will help to overcome issues related to physical and chemical composition, storage, and logistics to successfully co-fire higher percentages of biomass ( > 40%) with coal.

EFFECT OF NaF AND SnO{sub 2} ON PORTLAND CEMENT CLINKER FABRICATION  

SciTech Connect

The paper aimed at studying the effect of NaF and SnO{sub 2} employed as mineralisers on Portland cement clinker fabrication. In order to do this, the raw mix included in turn 0.5% NaF, 0.5% SnO{sub 2}, and a combination of 0.5% NaF and 0.5% SnO{sub 2}, all expressed as weight percentages of the raw mix. The effects of the presence of NaF and SnO{sub 2} mineralisers on the raw mix were studied by investigations of the loss on ignition at 700 deg. C and 800 deg. C with calculating the corresponding decarbonation ratio of the raw mix, determination of free lime and XRD analysis. NaF was found to have a positive effect both during the decarbonation of the raw mix and during the formation of minerals in clinker. On the other hand, SnO{sub 2} has but a little effect on the decarbonation process. Finally, the combined use of NaF and SnO{sub 2} modifies the kinetics of binding the free lime to the effect of accelerating the process as compared to the separate use of each mineraliser.

The impact of the number of excised axillary nodes and of the percentage of involved nodes on regional nodal failure in patients treated by breast-conserving surgery with or without regional irradiation  

SciTech Connect

Purpose: After breast-conserving surgery, recommendations for regional nodal radiotherapy are usually based on the number of positive nodes. This number is dependent on the number of nodes removed during the axillary dissection. This study examines whether the percentage of positive nodes may help to select patients for regional radiotherapy. Methods and Materials: A retrospective study was conducted on 1,372 T1-T2 node-positive breast cancer patients treated at L'Hotel-Dieu de Quebec Hospital between 1972 and 1997. Results: Among the patients who did not receive regional radiotherapy, the percentage of involved nodes was significantly associated with axillary failure. Ten-year axillary control rates were 97% and 91% when the percentage of involved nodes was <50% and {>=}50%, respectively (p = 0.007). In addition, regional radiotherapy is always significantly associated with a decrease in overall regional failure (axillary and/or supraclavicular), regardless of the percentage of involved nodes. However, regional radiotherapy reduced the axillary failure rate (2% vs. 9%, p = 0.007) only when more than a specific percentage of nodes was involved ({>=}40% if N1-3 and {>=}50% if N>3 nodes). Conclusions: The percentage of involved nodes should be taken into consideration in selecting patients for regional radiotherapy.

Effect of different percentages of biodieseldiesel blends on injection, spray, combustion, performance, and emission characteristics of a diesel engine  

Science Journals Connector (OSTI)

Abstract A comparative study of effect of different biodieseldiesel blends (B5, B10, B15, B20, B25, B50 and B100) on injection, spray, combustion, performance, and emissions of a direct injection diesel engine at constant speed (1500rpm) was carried out. The penetration distance increased with increase in percentage of biodiesel in diesel due to enhanced in-line fuel pressure. The simulation results indicate the spray penetration with biodieseldiesel blend up to B15 does not lead to wall impingement but B20 is to be a critical limit of wall impingement (within uncertainty 1.3%). However, it is observed clearly from the simulation results that probability of wall impingement is more with higher blends (B25, B50 and B100). The ignition delay period decreased with all biodiesel blends due to higher cetane number resulting in less rate of pressure rise and the smooth engine running operation. The engine torque does not change significantly with biodieseldiesel blends up to 20% (B20). However, the torque reduction is about 2.7% with B100 at the rated load. Carbon monoxide (CO), hydrocarbon (HC) and smoke emissions decreased with all biodieseldiesel blends. However, oxides of nitrogen (NOx) emission increased in the range of 1.422.8% with all biodieseldiesel blends at rated load due to oxygenated fuel, automatic advance in dynamic injection timing (DIT), higher penetration and higher in-cylinder temperature. A notable conclusion emerged from this study is the optimum biodieseldiesel blend based on no wall impingement (B15: 0% and B20 1.3% uncertainty limit) and increase in \\{NOx\\} emission (B15: 4.1% and B20: 15.6%) in a conventional (unmodified) diesel engine is up to B15.

Defective graphene as promising anode material for Na-ion battery and Ca-ion battery  

E-Print Network (OSTI)

We have investigated adsorption of Na and Ca on graphene with divacancy (DV) and Stone-Wales (SW) defect. Our results show that adsorption is not possible on pristine graphene. However, their adsorption on defective sheet is energetically favorable. The enhanced adsorption can be attributed to the increased charge transfer between adatoms and underlying defective sheet. With the increase in defect density until certain possible limit, maximum percentage of adsorption also increases giving higher battery capacity. For maximum possible DV defect, we can achieve maximum capacity of 1459 mAh/g for Na-ion batteries (NIBs) and 2900 mAh/g for Ca-ion batteries (CIBs). For graphene full of SW defect, we find the maximum capacity of NIBs and CIBs is around 1071 mAh/g and 2142 mAh/g respectively. Our results will help create better anode materials with much higher capacity and better cycling performance for NIBs and CIBs.

Investigation of SiO{sub 2}:Na{sub 2}O ratio as a corrosion inhibitor for metal alloys  

SciTech Connect

The silicate is one of the potential compounds used as a corrosion inhibitor for metal alloys. The mixture between silica and sodium hydroxide (NaOH) succeeded to produce the silicate product. The formulation of a silicate product normally variable depended by the different ratio of SiO{sub 2}:Na{sub 2}O. This research utilized the agriculture waste product of paddy using its rice husk. In this study, the amorphous silica content in rice husk ash was used after rice husk burnt in a muffle furnace at a certain temperature. The X-ray diffraction (XRD) analysis was done to determine the existence of amorphous phase of silica in the rice husk ash. There are several studies that recognized rice husk as an alternative source that obtained high silica content. The X-ray fluorescence (XRF) analysis was carried out to clarify the percentage amount of Si and O elements, which referred the silica compound in rice husk ash. The preparation of sodium silicate formulation were differ based on the SiO{sub 2}:Na{sub 2}O ratio (SiO{sub 2}:Na{sub 2}O ratio = 1.00, 2.00 and 3.00). These silicate based corrosion inhibitors were tested on several testing samples, which were copper (99.9%), aluminum alloy (AA 6061) and carbon steel (SAE 1045). The purpose of this study is to determine the appropriate SiO{sub 2}:Na{sub 2}O ratio and understand how this SiO{sub 2}:Na{sub 2}O ratio can affect the corrosion rate of each metal alloys immersed in acidic medium. In order to investigate this study, weight loss test was conducted in 0.5 M hydrochloric acid (HCl) for 24 hours at room temperature.

Lattice Dynamics of NaF  

Science Journals Connector (OSTI)

The results of an extended calculation of the normal modes of the NaF lattice are presented. Three models have been considered: a "rigid-ion" (RI) model, a "deformation-dipole" model with central F--F- short-range interactions (DDNNN), and a "deformation-dipole" model including both central F--F- interactions and a noncentral component in the first-neighbor, short-range interactions [DDNNN(NC)]. For each of these models we have derived frequency spectra for both 300 and 0K input parameters, the associated dispersion curves for symmetry directions, Debye characteristic temperatures ?D, moment functions ?D(n), and the Na+ and F- Debye-Waller parameters B1 and B2 and their ratio B1B2. Of the three models, the two DD variations give good agreement with the observed dispersion curves, the DDNNN models being slightly better and giving somewhat closer agreement with the observed B values.

The high-frequency exponential wing of the reststrahlen band of NaF is decomposed into a number of N-phonon absorption spectra (N=2,3,4,5) by means of a temperature analysis. Overall agreement of the individual spectra with recent theoretical predictions is good, except for a fairly pronounced structure which indicates particularly strong contributions from certain frequencies of the TO and LO phonon branches.

Gamow-Teller strength in Na23(n,p) and a comparison to Na23(?-,?)  

Science Journals Connector (OSTI)

We report measurements of the Na23(n,p) differential cross section at an incident energy of 198 MeV and angles from 0 to 24 using the TRIUMF Charge Exchange Facility. From these data we determine Gamow-Teller (GT) transition probabilities to low lying 1/2+, 3/2+, and 5/2+ Ne23 states and the GT+ strength distribution up to 25 MeV excitation energy. The values of BGT+ to discrete states, and the GT+ strength below 10 MeV, are found to be in reasonable agreement with a full 1s-0d shell model calculation with a normalization factor of about 0.74. The GT+ strength above 10 MeV suggests the removal of strength from lower to higher excitation energies. We also compare the Na23(n,p) data with Na23(?-,?) data and find agreement between the values of BGT+ to discrete levels extracted from the (n,p) and (?-,?) reactions. The general consistency of the (n,p) and (?-,?) data, and the full 1s-0d shell model calculation, give confidence in a recent extraction of the weak pseudoscalar coupling from ?- capture on Na23. Finally, using both ?--decay and ?- capture data, we obtain unit cross sections from the Na23(n,p) measurement.

Multiphonon Absorption in NaF  

Science Journals Connector (OSTI)

The infrared absorption in NaF at the two CO2 laser wavelengths 10.6 and 9.3 ?m was measured between 4 and 400 K. The results complement the previously measured absorption for higher temperatures, and allow for a detailed comparison with theoretical predictions. The experimental temperature dependence at 10.6 ?m can be excellently fitted by a curve expected for three-phonon processes in the whole temperature range; the absorption at 9.3 ?m fits a mixture of three- and four-phonon processes.

Hydrogen Storage in Diamond Powder Utilizing Plasma NaF Surface Treatment for Fuel Cell Applications  

SciTech Connect

Hydrogen Fuel Cells offer the vital solution to the world's socio-political dependence on oil. Due to existing difficulty in safe and efficient hydrogen storage for fuel cells, storing the hydrogen in hydrocarbon compounds such as artificial diamond is a realistic solution. By treating the surface of the diamond powder with a Sodium Fluoride plasma exposure, the surface of the diamond is cleaned of unwanted molecules. Due to fluorine's electro negativity, the diamond powder is activated and ready for hydrogen absorption. These diamond powder pellets are then placed on a graphite platform that is heated by conduction in a high voltage circuit made of tungsten wire. Then, the injection of hydrogen gas into chamber allows the storage of the Hydrogen on the surface of the diamond powder. By neutron bombardment in the nuclear reactor, or Prompt Gamma Neutron Activation Analysis, the samples are examined for parts per million amounts of hydrogen in the sample. Sodium Fluoride surface treatment allows for higher mass percentage of stored hydrogen in a reliable, resistant structure, such as diamond for fuel cells and permanently alters the diamonds terminal bonds for re-use in the effective storage of hydrogen. The highest stored amount utilizing the NaF plasma surface treatment was 22229 parts per million of hydrogen in the diamond powder which amounts to 2.2229% mass increase.

On the 21Na(p,gamma)22Mg thermonuclear rate for 22Na production in novae  

E-Print Network (OSTI)

Classical novae are potential sources of gamma-rays, like the 1.275 MeV gamma emission following 22Na beta decay, that could be detected by appropriate instruments on board of future satellites like INTEGRAL. It has been shown that the production of 22Na by novae is affected by the uncertainty on the 21Na(p,gamma)22Mg rate and in particular by the unknown partial widths of the Ex = 5.714 MeV, J^pi = 2^+, 22Mg level. To reduce these uncertainties, we performed shell model calculations with the OXBASH code, compared the results with available spectroscopic data and calculated the missing partial widths. Finally, we discuss the influence of these results on the 21Na(p,gamma)22Mg reaction rate and 22Na synthesis.

Low-Frequency Dielectric Constant of LiF, NaF, NaCl, NaBr, KCl, and KBr by the Method of Substitution  

Science Journals Connector (OSTI)

The 1000-Hz 300K dielectric constants of some alkali halides were measured to an accuracy of 0.01% by the method of substitution. Reproducibly different values for various crystals of the same type were obtained which varied beyond the experimental error. The ranges of results for various crystals of each type measured are LiF, 9.0355-9.0360; NaF, 5.0719-5.0722; NaCl, 5.8940-5.8956; NaBr, 6.3957-6.3974; KCl, 4.8112-4.8182; and KBr, 4.8735-4.8762. The spread for each type of crystal is thought to be attributable to random trace impurities. The numbers are discussed in the light of past values.

Nuclear Double Resonance Study of Na First-Order Quadrupole Splittings in a NaF-LiF Mixed Crystal  

Science Journals Connector (OSTI)

A nuclear magnetic double resonance experiment has been performed to measure the high-field first-order quadrupole splittings of Na23 nuclei located in the vicinity of Li+ substitutional impurities in a single crystal of NaF. The observed quadrupole-shifted frequency of those Na23 nuclei located at (1,0,1)-type sites [relative to the Li+ impurity at the (0,0,0) lattice site] was e2qQh=(54410) kHz with an asymmetry parameter ?=0.650.05. For those Na23 nuclei at (0,0,2)-type sites, e2qQh=(85610) kHz with ?=0. The values of eq and ? thus obtained are compared with theoretical calculations. A mathematical analysis of the high-field double resonance process as it applies to rare, quadrupole-interacting nuclei is also presented.

A Complete Basis Set Estimate of Cation-p Bond Strengths: Na+(ethylene) and Na+(benzene)  

SciTech Connect

Large scale second order perturbation theory and couple cluster theory calculations were performed on the Na+(ethylene) and Na+(benzene) complexes in an effort to estimate binding enthalpies in the complete basis set limit. The resulting best estimates are DH0[Na+(ethylene)] = -13.7 ? 0.2 kcal/mol and DH0[Na+(benzene)] = -23.9 ? 0.3 kcal/mol, which include small corrections for core/valence correlation effects. The former value can be compared to a measurement of -10.3 ? 1.0 kcal/mol obtained from collision induced dissociation, while the latter value is approximately midway between the two existing experimental values which differed by 6.5 kcal/mol. For the basis sets considered in this study, the counterpoise-corrected binding energies were found to be in much worse agreement with the complete basis set limit than the raw values.

Measurement of low-energy Na^+ -- Na total collision rate in an ion--neutral hybrid trap  

E-Print Network (OSTI)

We present measurements of the total elastic and resonant charge-exchange ion-atom collision rate coefficient $k_\\mathrm{ia}$ of cold sodium (\\ce{Na}) with optically-dark low energy \\ce{Na+} ions in a hybrid ion-neutral trap. To determine $k_\\mathrm{ia}$, we measured the trap loading and loss from both a \\ce{Na} magneto-optical trap (MOT) and a linear radio frequency quadrupole Paul trap. We found the total rate coefficient to be $7.4 \\pm 1.9 \\times 10^{-8}$ cm$^3$/s for the type I \\ce{Na} MOT immersed within an $\\approx 140$ K ion cloud and $1.10 \\pm 0.25 \\times 10^{-7}$ cm$^3$/s for the type II \\ce{Na} MOT within an $\\approx 1070$ K ion cloud. Our measurements show excellent agreement with previously reported theoretical fully quantal \\textit{ab initio} calculations. In the process of determining the total rate coefficient, we demonstrate that a MOT can be used to probe an optically dark ion cloud's spatial distribution within a hybrid trap.

Investigation of thermonuclear $^{18}$Ne($?$,$p$)$^{21}$Na rate via resonant elastic scattering of $^{21}$Na+$p$  

E-Print Network (OSTI)

The $^{18}$Ne($\\alpha$,$p$)$^{21}$Na reaction is thought to be one of the key breakout reactions from the hot CNO cycles to the rp-process in type I x-ray bursts. In this work, the resonant properties of the compound nucleus $^{22}$Mg have been investigated by measuring the resonant elastic scattering of $^{21}$Na+$p$. An 89 MeV $^{21}$Na radioactive beam delivered from the CNS Radioactive Ion Beam Separator bombarded an 8.8 mg/cm$^2$ thick polyethylene (CH$_{2}$)$_{n}$ target. The $^{21}$Na beam intensity was about 2$\\times$10$^{5}$ pps, with a purity of about 70% on target. The recoiled protons were measured at the center-of-mass scattering angles of $\\theta_{c.m.}$$\\approx$175.2${^\\circ}$, 152.2${^\\circ}$, and 150.5${^\\circ}$ by three sets of $\\Delta E$-$E$ telescopes, respectively. The excitation function was obtained with the thick-target method over energies $E_x$($^{22}$Mg)=5.5--9.2 MeV. In total, 23 states above the proton-threshold in $^{22}$Mg were observed, and their resonant parameters were determined via an $R$-matrix analysis of the excitation functions. We have made several new $J^{\\pi}$ assignments and confirmed some tentative assignments made in previous work. The thermonuclear $^{18}$Ne($\\alpha$,$p$)$^{21}$Na rate has been recalculated based on our recommended spin-parity assignments. The astrophysical impact of our new rate has been investigated through one-zone postprocessing x-ray burst calculations. We find that the $^{18}$Ne($\\alpha$,$p$)$^{21}$Na rate significantly affects the peak nuclear energy generation rate, reaction fluxes, as well as the onset temperature of this breakout reaction in these astrophysical phenomena.

Thermal stability of the endohedral fullerenes NaC60, NaC70, and PaC60  

Science Journals Connector (OSTI)

Nitrogen and phosphorus atoms enclosed in fullerenes keep their atomic ground-state configuration, and no charge transfer or covalent bonding to the cage occurs. These systems can be dissolved in organic solvents and reacted with addends without losing the atomic character of the guest atom. In this paper, we present a detailed study of the annealing behavior of NaC60, NaC70, PaC60, and of some NaC60 adducts. The disintegration of these systems, as recorded by electron paramagnetic resonance measurements, occurs in the temperature range between 400 K and 600 K. The results are in qualitative agreement with potential energy calculations and confirm the proposed escape mechanism that proceeds via bond formation of the trapped atom with the cage. It is found that other combinations of group-V elements with fullerenes, e.g., NaC84, PaC70, and AsaC60 are not stable at room temperature. The escape mechanism and the possibility of disabling this path are discussed.

Adsorptive removal of tetrahydrothiophene (THT) and tert-butylmercaptan (TBM) using Na-Y and AgNa-Y zeolites for fuel cell applications  

Science Journals Connector (OSTI)

Adsorptive removal of tetrahydrothiophene (THT) and tert-butylmercaptan (TBM) that are widely used sulfur odorants in pipeline natural gas was studied using AgNa-Y zeolites at ambient temperature and atmospheric pressure. The AgNa-Y were obtained via Ag+-exchange with Na+ of Na-Y at various exchange levels, and the contributions of formed adsorption sites (Ag+, Na+, Ag0, H+, and Ag2O) in the THT and TBM adsorption uptake and selectivity were characterized. THT adsorption strength on these sites followed an order of Ag+>Na+?Ag0>H+>Ag2O. The adsorption strength of THT on Na+ sites was sufficiently high, thus an increase in the Ag+-exchange level did not lead to a notable increase in the breakthrough THT uptake. Differently, adsorption of TBM on Na+ sites was weak, whereas that on Ag+ sites was strong. This resulted in a marked increase in the breakthrough TBM uptake with an increase in the Ag+-exchange level, showing an order of magnitude higher uptake on AgNa-Y compared with that on Na-Y. Noticeably, the adsorption strength of THT on these adsorption sites was higher than that of TBM. This resulted in an almost 100% adsorption selectivity for THT over TBM, when these two sulfur species coexisted in the feed stream.

Na sup + -K sup + -ATPase-dependent sodium flux in cortical collecting tubule  

SciTech Connect

The instantaneous rate of efflux of intracellular Na was studied in rabbit isolated cortical collecting tubules (CCT) as a function of temperature and intracellular Na concentration ((Na){sub i}). (Na){sub i} of microdissected CCT was increased by cold and K-free exposure in the presence of {sup 22}Na and the extracellular tracer ({sup 3}H)sorbitol. (Na){sub i} rose rapidly to 40 mM at 30 min, after which it rose more slowly, reaching 120-140 mM at 6 h. Kinetics of Na efflux were studied after rapid rewarming, using a special device allowing measurements at 20-s intervals. Under control conditions, the total Na load was extruded in <8 min, whereas, in the presence of 10{sup {minus}4} M ouabain, only 50% of the load was extruded during this period of time. Ouabain-sensitive Na efflux was first evident at 13{degree}C and gradually increased between 13 and 35{degree}C. At 37{degree}C, Na{sup +}-K{sup +}-ATPase-dependent Na efflux was dependent on (Na){sub i}. This efflux gradually increased, from 0.05 to 0.5 peq{center dot}nl tubular volume{sup {minus}1}{center dot}s{sup {minus}1} as a function of (Na){sub i} and reached a plateau at 70 mM (Na){sub i}. It is concluded that (Na){sub i} is a major modulator of the pump activity in CCT; at normal levels of (Na){sub i}, the pump is operating at only a small fraction of its total capacity.

Properties of F Centers in NaF  

Science Journals Connector (OSTI)

A weak intensity emission, centered at 785 m?, is identified as the F photoluminescence in NaF. The temperature dependence of photoionization and photoluminescence of F centers is investigated. Two thermal activation energies are found: ?EL=0.06 eV for the photoluminescence, and ?E1=0.12 eV for the photoionization efficiency. The nature of the quenching mechanism of the F luminescence is discussed.

Cosmogenic radionuclide production in NaI(Tl) crystals  

E-Print Network (OSTI)

The production of long-lived radioactive isotopes in materials due to the exposure to cosmic rays on Earth surface can be an hazard for experiments demanding ultra-low background conditions, typically performed deep underground. Production rates of cosmogenic isotopes in all the materials present in the experimental set-up, as well as the corresponding cosmic rays exposure history, must be both well known in order to assess the relevance of this effect in the achievable sensitivity of a given experiment. Although NaI(Tl) scintillators are being used in experiments aiming at the direct detection of dark matter since the first nineties of the last century, very few data about cosmogenic isotopes production rates have been published up to date. In this work we present data from two 12.5 kg NaI(Tl) detectors, developed in the frame of the ANAIS project, which were installed inside a convenient shielding at the Canfranc Underground Laboratory just after finishing surface exposure to cosmic rays. The very fast start of data taking allowed to identify and quantify isotopes with half-lives of the order of tens of days. Initial activities underground have been measured and then production rates at sea level have been estimated following the history of detectors; values of about a few tens of nuclei per kg and day for Te isotopes and 22Na and of a few hundreds for I isotopes have been found. These are the first direct estimates of production rates of cosmogenic nuclides in NaI crystals. A comparison of the so deduced rates with calculations using typical cosmic neutron flux at sea level and a carefully selected description of excitation functions will be also presented together with an estimate of the corresponding contribution to the background at low and high energies, which can be relevant for experiments aiming at rare events searches.

Benchmarking EUV mask inspection beyond 0.25 NA  

SciTech Connect

The SEMATECH Berkeley Actinic Inspection Tool (AIT) is an EUV-wavelength mask inspection microscope designed for direct aerial image measurements, and pre-commercial EUV mask research. Operating on a synchrotron bending magnet beamline, the AIT uses an off-axis Fresnel zoneplate lens to project a high-magnification EUV image directly onto a CCD camera. We present the results of recent system upgrades that have improved the imaging resolution, illumination uniformity, and partial coherence. Benchmarking tests show image contrast above 75% for 100-nm mask features, and significant improvements and across the full range of measured sizes. The zoneplate lens has been replaced by an array of user-selectable zoneplates with higher magnification and NA values up to 0.0875, emulating the spatial resolution of a 0.35-NA 4 x EUV stepper. Illumination uniformity is above 90% for mask areas 2-{micro}m-wide and smaller. An angle-scanning mirror reduces the high coherence of the synchrotron beamline light source giving measured {sigma} values of approximately 0.125 at 0.0875 NA.

Formation and Structural Analysis of a Surface Alloy: Al(111)-(2 2)-Na  

Science Journals Connector (OSTI)

The Al(111)-(2 2)-Na phase formed by adsorption of one-half monolayer Na at 300 K is shown to be a surface alloy. Quantitative agreement is achieved between the results of structure determinations by low energy electron diffraction, surface extended x-ray adsorption fine structure, and total energy calculations. The first four layers of the structure are shown to consist of a Na-Al-Na sandwich on a reconstructed Al substrate layer. It is suggested that the formation of the structure involves surface steps as sources of Al atoms.

High Energy Density Na-S/NiCl2 Hybrid Battery  

SciTech Connect

High temperature (250-350C) sodium-beta alumina batteries (NBBs) are attractive energy storage devices for renewable energy integration and other grid related applications. Currently, two technologies are commercially available in NBBs, e.g., sodium-sulfur (Na-S) battery and sodium-metal halide (ZEBRA) batteries. In this study, we investigated the combination of these two chemistries with a mixed cathode. In particular, the cathode of the cell consisted of molten NaAlCl4 as a catholyte and a mixture of Ni, NaCl and Na2S as active materials. During cycling, two reversible plateaus were observed in cell voltage profiles, which matched electrochemical reactions for Na-S and Na-NiCl2 redox couples. An irreversible reaction between sulfur species and Ni was identified during initial charge at 280C, which caused a decrease in cell capacity. The final products on discharge included Na2Sn with 1< n < 3, which differed from Na2S3 found in traditional Na-S battery. Reduction of sulfur in the mixed cathode led to an increase in overall energy density over ZEBRA batteries. Despite of the initial drop in cell capacity, the mixed cathode demonstrated relatively stable cycling with more than 95% of capacity retained over 60 cycles under 10mA/cm2. Optimization of the cathode may lead to further improvements in battery performance.

Science Journals Connector (OSTI)

The electron-nuclear double resonance (ENDOR) method is applied to the study of the structure of the F center in NaF. Hyperfine interactions between the F-center electron and a number of the surrounding nuclear shells are presented and compared with the results of earlier experiments and with theory. It is found that the resolved hyperfine structure is not due to the predominance of the first-shell interaction, as has been thought, but it arises from the fortuitous equality of the first- and second-shell isotropic hyperfine interactions. Electron paramagnetic resonance (EPR) absorption measurements of the resolved structure confirms an expected 31-line resolved pattern. The exceptional resolution found in the ENDOR spectrum permits the identification of interactions with nuclei well beyond the eighth shell. Although the samples also contained large numbers of M centers, no evidence for a paramagnetic M center was found in either the EPR or ENDOR spectra.

n-Selective Single Capture Following Xe{sup 18+} And Xe{sup 54+} Impact On Na(3s) And Na*(3p)  

SciTech Connect

State selective single charge exchange n-level cross sections are calculated for collisions of Xe18+ and Xe54+ ions with Na(3s) and Na*(3p) over the energy range of 0.1 to 10.0 keV/amu. The CTMC method is used which includes all two-body interactions. Experimental state-selective cross sections and their corresponding transverse momentum spectra for Xe18+ are found to be in reasonable accord with the calculations.

Stability of graphene band structures against an external periodic perturbation: Na on graphene  

Science Journals Connector (OSTI)

The electronic structure of Na-adsorbed graphenes formed on the 6H-SiC(0001) substrate was studied using angle-resolved photoemission spectroscopy with synchrotron photons and ab initio pseudopotential calculations. It was found that the band of the graphenes sensitively changes upon Na adsorption especially at low temperature. With increasing Na dose, the ? band appears to be quickly diffused into the background at 85 K whereas it becomes significantly enhanced with its spectral intensity at room temperature (RT). A new parabolic band centered at k?1.15??1 also forms near Fermi energy with Na at 85 K while no such band was observed at RT. Such changes in the band structure are found to be reversible with temperature. The changes in the ? band of graphene are mainly driven by the Na-induced potential especially at low temperature where the potential becomes periodic due to the crystallized Na overlayer. The new parabolic band turns out to be the ? band of the underlying buffer layer partially filled by the charge transfer from Na adatoms. The increase in the hopping rate of Na adatoms at RT by 5 orders of magnitude prevents such a charge transfer, explaining the absence of the new band at RT.

Concentration and precipitation of NaCl and KCl from salt cake leach solutions by electrodialysis  

SciTech Connect

Electrodialysis was investigated for cost-effective recovery of salt from salt cake leach solutions. (Salt cake is a waste stream generated by the aluminum industry during treatment of aluminum drosses and scrap.) We used a pilot-scale electrodialysis stack of 5 membrane pairs, each with an effective area of 0.02 m{sup 2}. The diluate stream contained synthetic NaCl, KCl,mixtures of NaCl and KCl, and actual salt cake leach solutions (mainly NaCl and KCl, with small amounts of MgCl{sub 2}). We concentrated and precipitated NaCl and KCl salts from the concentrate steam when the initial diluate stream concentration was 21.5 to 28.8 wt% NaCl and KCl. We found that water transferring through the membranes was a significant factor in overall efficiency of salt recovery by electrodialysis.

What the NA60 dilepton data can tell  

E-Print Network (OSTI)

The NA60 experiment has studied low-mass muon pair production in In-In collisions at 158 AGeV with unprecedented precision. Thus, there is hope that the in-medium modifications of the vector meson spectral function can be constrained more thoroughly than from previous experiments. Towards this goal, we present a study comparing different models for the in-medium modification of vector mesons. In particular, we investigate what can be learned about collisional broadening by a medium at finite temperature and baryon density and what model independent constraints can be obtained from the data. Of special relevance is a comparison to $p_T$-cuts of the dilepton spectra. Those not only provide independent tests of the evolution model and $p_T$-dependence of the spectral function but also unambiguously decide if the observed yield in the higher mass spectrum $M > 1 {\\rm GeV}$ is mainly due to the hot phase of the evolution or four pion annihilation processes.

Inhibition of Na -P/sub i/ cotransporter in small gut brush border by phosphonocarboxylic acids  

SciTech Connect

The authors examined the effect of phosphonoformic acid (PFA) and phosphonoacetic acid (PAA) upon Na -P/sub i/ cotransport in brush-border membrane (BBM) from small gut of rat. Both PFA and PAA inhibited the Na gradient-dependent uptake of TSP/sub i/ by BBM vesicles (BBMV) prepared from intestinal mucosa but had no effect on Na -dependent uptakes of D-(TH)glucose, L-(TH)proline, or ( UC)succinate. The uptake in the absence of Na gradient, or uptake at equilibrium period (180 min), was not affected by PFA or by PAA. A chemical analogue of PFA and PAA, phosphonopropionic acid, had only a minor inhibitory effect and phenylphosphonic acid was inactive. Neither PFA nor PAA influenced the activity of rat intestinal BBM alkaline phosphatase. The BBMV from rat jejunum had a much higher capacity for Na gradient-dependent uptake of TSP/sub i/ than BBMV from duodenum or ileum. The inhibition of BBMV TSP/sub i/ transport across rat jejunum by PFA is competitive. They suggest that PFA and PAA are specific inhibitors of Na gradient-dependent uptake of P/sub i/ by BBMV from small intestinal mucosa and that they could serve as useful experimental tools for the studies of intestinal Na -P/sub i/ cotransport.

Investigation of the Effects of Biodiesel-based Na on Emissions Control Components  

SciTech Connect

A single-cylinder diesel engine was used to investigate the impact of biodiesel-based Na on emissions control components using specially blended 20% biodiesel fuel (B20). The emissions control components investigated were a diesel oxidation catalyst (DOC), a Cu-zeolite-based NH{sub 3}-SCR (selective catalytic reduction) catalyst, and a diesel particulate filter (DPF). Both light-duty vehicle, DOC-SCR-DPF, and heavy-duty vehicle, DOC-DPF-SCR, emissions control configurations were employed. The accelerated Na aging is achieved by introducing elevated Na levels in the fuel, to represent full useful life exposure, and periodically increasing the exhaust temperature to replicate DPF regeneration. To assess the validity of the implemented accelerated Na aging protocol, engine-aged lean NO{sub x} traps (LNTs), DOCs and DPFs are also evaluated. To fully characterize the impact on the catalytic activity the LNT, DOC and SCR catalysts were evaluated using a bench flow reactor. The evaluation of the aged DOC samples and LNT show little to no deactivation as a result of Na contamination. However, the SCR in the light-duty configuration (DOC-SCR-DPF) was severely affected by Na contamination, especially when NO was the only fed NO{sub x} source. In the heavy-duty configuration (DOC-DPF-SCR), no impact is observed in the SCR NO{sub x} reduction activity. Electron probe micro-analysis (EPMA) reveals that Na contamination on the LNT, DOC, and SCR samples is present throughout the length of the catalysts with a higher concentration on the washcoat surface. In both the long-term engine-aged DPF and the accelerated Na-aged DPFs, there is significant Na ash present in the upstream channels; however, in the engine-aged sample lube oil-based ash is the predominant constituent.

Thermochemistry of phosphorus oxynitrides: PON and LiNaPON glasses  

SciTech Connect

High-temperature solution calorimetry has been very useful in elucidating the energetics of many oxide materials. Recently, a sodium molybdate melt, 3Na{sub 2}O{center{underscore}dot}4MoO{sub 3}, has been shown to be very effective for nitride calorimetry. This methodology has now been used to determine the energetics of formation of phosphorus oxynitride PON samples and of a series of LiNaPON oxynitride glasses. The magnitude of the energetics of nitrogen/oxygen substitution within PON and LiNaPON glasses has been correctly evaluated by using N-N, O-O, P-N, and P-O bond strengths. The in-situ precipitation of metallic particles from corresponding oxides in LiNaPON glasses has been predicted from high-temperature solution calorimetry results and appropriate thermodynamic cycles. The results constitute the first set of energetic data on nitridophosphates.

Carbon monoxide adsorption/desorption processes over NaX zeolite and supported ruthenium catalyst  

SciTech Connect

The binding states of CO on NaX zeolite and RuNaX were investigated by thermal desorption spectroscopy. Desorption peaks centered at around 390, 430, 490, and 520 K were observed from NaX following room-temperature adsorption of CO. The activation energy values corresponding to these peaks were calculated to be 41.4, 45.7, 53.8, and 57.7 kJ mol{sup {minus}1}, respectively. These peaks were also observed in desorption profiles from RuNaX although their temperatures were higher by 10 to 20 K. In addition, the desorption spectra from RuNaX also comprise two high-temperature peaks at around 575 and 640 K. With both the RuNaX and the NaX samples the temperature and relative intensities of the desorption peaks depended on pretreatment conditions and on the lapsed time between CO exposure to the sample and the commencement of programmed heating. Mass spectral analysis revealed that the gas desorbed at 300-500 K consisted mainly of CO while at higher temperatures CO{sub 2} was the main component. The desorption peaks below 500 K are attributed to the release of carbon monoxide from structural and intragranular or intergranular zeolitic pores. Lewis sites on the zeolite surface are found to facilitate activation of CO, resulting in its transformation to CO{sub 2}. The initial adsorption of carbon monoxide in zeolite pores and subsequent diffusion to metal sites leading to its disproportionation/oxidation is found to play an important role in the CO adsorption/desorption process on RuNaX.

Cell volume variation under different concentrations of saline solution (NaCL)  

Science Journals Connector (OSTI)

RESUMENIntroduccin: Dentro de las prcticas clnicas, es de suma importancia conocer la relacin volumtrica entre la contraccin celular y la concentracin de solucin salina (NaCl). Mtodos: Muestras de sangre por parte de voluntarios que gozan de buena salud fueron expuestas a diferentes concentraciones de NaCl, las cuales oscilan entre 0.42% a 11.70%, observndose la variacin resultante en el hematocrito. Se estudi la variacin del volumen celular como funcin de la correspondiente concentracin de NaCl. Se lleg a establecer una ecuacin que predice tericamente el comportamiento observado. Resultados: Examinamos 53 muestras de sangre provenientes de 12 voluntarios sanos. La relacin entre la contraccin celular y la concentracin de NaCl muestra que la mxima contraccin del volumen celular se obtiene cuando el NaCl est en alrededor de 5.85%. Se resume el modelo matemtico resultante en la ecuacin. ?V denota la variacin celular a la correspondiente concentracin de NaCl. Este modelo presenta un coeficiente de regresin lineal de 0.996 y aplicando el Chi-square goodness of fit test [es una prueba estadstica] se observa un nivel de confianza superior a 99.5%. Igualmente, es menester mencionar que las concentraciones de NaCl iguales o superiores a 7.02% provoca cierto grado de hemlisis. Conclusiones: No hay razn para utilizar concentraciones de NaCl superiores a 5.85%. Concentraciones ms altas no inducen una mayor contraccin del volumen celular, pero s provocan lesin celular.41CV=?

Selective catalytic reduction of NO{sub 2} with urea in nanocrystalline NaY zeolite  

SciTech Connect

In this study, the selective catalytic reduction (SCR) of NO{sub 2} with urea in nanocrystalline NaY zeolite was investigated with in situ transmission Fourier transform infrared (FTIR) spectroscopy and solid-state nuclear magnetic resonance spectroscopy. At T=473 K, the reaction rate for urea-SCR of NO{sub 2} in nanocrystalline NaY zeolite was significantly greater than that in commercial NaY zeolite with a larger crystal size. In addition, a dramatic decrease in the concentration of undesirable surface species, including biuret and cyanuric acid, was observed in nanocrystalline NaY compared with commercial NaY after urea-SCR of NO{sub 2} at T=473 K. The increased reactivity for urea-SCR of NO{sub 2} was attributed to silanol groups and extra-framework aluminum species located on the external surface of nanocrystalline NaY. Specifically, NOx storage as nitrate and nitrite on the internal zeolite surface was coupled to reactive deNOx sites on the external surface. Isotopic labeling combined with IR analysis suggest that NN bond formation involved both an N-atom originating from NO{sub 2} and an N-atom originating from urea. This is the first clear example demonstrating that the increased external surface area (up to 40% of total surface area) of nanocrystalline zeolites can be used as a reactive surface with unique active sites for catalysis.

Synthesis and characterization of NaMt biocomposites with corn cob xylan in aqueous media  

Science Journals Connector (OSTI)

In this study synthesis and characterization of biopolymer/clay biocomposites was aimed using naturally occurring polysaccharide (xylan) as biopolymer and montmorillonite type clay (NaMt). Xylan was extracted from corn cobs via alkaline oxidative treatment. Maximum solubility of xylan was determined as 1% (w/v) in water at room temperature. Thus synthesis was realized following two routes; first NaMt concentration was kept constant at 2.0נ10?2g/ml and xylan concentration was changed. Latter xylan concentration was kept constant at 1.0נ10?2g/ml and NaMt concentration was changed. Natural xylan, NaMt and biocomposites were examined in terms of their spectral, electrokinetic, rheologic, morphologic and thermal properties. Results showed that lower amounts of xylan interacted with NaMt on the surface, however, when the xylan amount was increased also intercalation of NaMt has occurred. Biocomposites showed better thermal and rheologic behaviors with respect to the starting materials.

At-wavelength interferometry of high-NA diffraction-limited EUV optics  

SciTech Connect

Recent advances in all-reflective diffraction-limited optical systems designed for extreme ultraviolet (EUV) lithography have pushed numerical aperture (NA) values from 0.1 to 0.3, providing Rayleigh resolutions of 27-nm. Worldwide, several high-NA EUV optics are being deployed to serve in the development of advanced lithographic techniques required for EUV lithography, including the creation and testing of new, high-resolution photoresists. One such system is installed on an undulator beamline at Lawrence Berkeley National Laboratory's Advanced Light Source. Sub{angstrom}-accuracy optical testing and alignment techniques, developed for use with the previous generations of EUV lithographic optical systems, are being extended for use at high NA. Considerations for interferometer design and use are discussed.

Caustic Recycle from Hanford Tank Waste Using NaSICON Ceramic Membrane Salt Splitting Process  

SciTech Connect

A family of inorganic ceramic materials, called sodium (Na) Super Ion Conductors (NaSICON), has been studied at Pacific Northwest National Laboratory (PNNL) to investigate their ability to separate sodium from radioactively contaminated sodium salt solutions for treating U.S. Department of Energy (DOE) tank wastes. Ceramatec Inc. developed and fabricated a membrane containing a proprietary NAS-GY material formulation that was electrochemically tested in a bench-scale apparatus with both a simulant and a radioactive tank-waste solution to determine the membrane performance when removing sodium from DOE tank wastes. Implementing this sodium separation process can result in significant cost savings by reducing the disposal volume of low-activity wastes and by producing a NaOH feedstock product for recycle into waste treatment processes such as sludge leaching, regenerating ion exchange resins, inhibiting corrosion in carbon-steel tanks, or retrieving tank wastes.

Two-dimensional charge fluctuation in ?-Na0.33V2O5  

Science Journals Connector (OSTI)

We have investigated the critical phenomena of the metal-to-insulator (MI) transition of ?-Na0.33V2O5. The critical exponent ? of 0.226(3) and anisotropic diffuse scattering suggest that the MI transition of ?-Na0.33V2O5 is two dimensional in nature and that the dimension of the order parameter is not Ising. The non-Ising-like order parameter indicates that the MI transition is not a simple order-disorder type such as that of ??-NaV2O5 but charge-density-wave like, where the valence at each V site is continuous and the arrangement is modulated. This closely corresponds to the situation predicted by neutron diffraction measurements [Nagai et al., J. Phys. Soc. Jpn. 74, 1297 (2005)] and NMR measurements [Itoh et al., Phys. Rev. B 74, 054434 (2006)].

An Evaluation of the NaS Battery Storage Potential for Providing Regulation Service in California  

SciTech Connect

Sodium sulfur (NaS) batteries can provide energy storage, real-time dispatch, regulation, frequency response, and other essential services to the power grids. This study presents the technical characteristics, modeling approach, methodologies, and results for providing regulation services in the California Independent System Operator (CAISO) market. Two different scenarios were studied and compared: a scenario without intermittent renewable-energy resource penetration (base case) and a scenario with significant renewable-energy resource penetration (including wind) reaching 20% of CAISOs energy supply. In addition, breakeven cost analyses were developed for four cases. Based on the results of the technical and cost analyses, the opportunities for the NaS battery providing the regulation services are discussed, design improvements for the batterys physical characteristics are recommended, and modifications of the regulation signals sent to NaS batteries are proposed.

Thermodynamic and kinetic analyses of the CO2 chemisorption mechanism on Na2TiO3: Experimental and theoretical evidences  

SciTech Connect

ABSTRACT: Sodium metatitanate (Na2TiO3) was successfully synthesized via a solid-state reaction. The Na2TiO3 structure and microstructure were characterized using X-ray diffraction, scanning and transmission electron microscopy, and N2 adsorption. Then, the CO2 chemisorption mechanism on Na2TiO3 was systematically analyzed to determine the influence of temperature. The CO2 chemisorption capacity of Na2TiO3 was evaluated both dynamically and isothermally, and the products were reanalyzed to elucidate the Na2TiO3?CO2 reaction mechanism. Different chemical species (Na2CO3, Na2O, and Na4Ti5O12 or Na16Ti10O28) were identified during the CO2 capture process in Na2TiO3. In addition, some CO2 chemisorption kinetic parameters were determined. The ?H? was found to be 140.9 kJ/mol, to the Na2TiO3?CO2 system, between 600 and 780 C. Results evidenced that CO2 chemisorption on Na2TiO3 highly depends on the reaction temperature. Furthermore, the experiments were theoretically supported by different thermodynamic calculations. The calculated thermodynamic properties of CO2 capture reactions by (Na2TiO3, Na4Ti5O12, and Na16Ti10O28) sodium titanates were fully investigated.

Differential thermal analysis of the liquidus relations in the system NaCl-H sub 2 O to 6 kbar  

SciTech Connect

The liquidus relations in the system NaCl-H{sub 2}O were investigated between 300 and 925C and between 0.4 and 6 kbar for compositions between 27.6 and 100 mol% NaCl by high-pressure differential thermal analysis. The PT slope of the liquidus increases from 10.5C/kbar for a composition with 27.6 mol% NaCl to 20.8C/kbar with 90 mol% NaCl to 21.8C/kbar with pure NaCl. The PT slope of the vapor saturation surface at the composition with 27.6 mol% NaCl is linear over the pressure range investigated and has a slope of 294C/kbar. On the basis of the experiments the composition of the liquids along the NaCl-rich part of the three-phase assemblage halite + liquid + vapor was determined: the liquid composition varies nearly linearly to within 0.5 wt% NaCl at temperatures above 480C, following the expression wt% (NaCl) = 0.1412T (C) - 12.96.

Static and dynamic polarizabilities of Na? within a variationally stable coupled-channel hyperspherical method  

Science Journals Connector (OSTI)

Using a model potential representation combined with a variationally stable method, we present a precise calculation of the electric dipole polarizabilities of the sodium negative ion (Na?). The effective two-electron eigensolutions for Na? are obtained from a hyperspherical coupled-channel calculation. This approach allows efficient error control and insight into the systems properties through one-dimensional potential curves. Our result of 1018.3a.u. for the static dipole polarizability is in agreement with previous calculations and supports our results for the dynamic polarizability, which has scarcely been investigated hitherto.

Off-center Tl and Na dopant centers in CsI  

SciTech Connect

We use density functional theory calculations to characterize the electronic and structural properties of the Tl and Na dopant centers in CsI. We nd that the Tl and Na centers can accept one or two electrons and couple to long-range relaxations in the surrounding crystal lattice to distort strongly off-center to multiple distinct minima, even without a triplet excitation. The long-range distortions are a mechanism to couple to phonon modes in the crystal, and are expected to play an important role in the phonon-assisted transport of polarons in activated CsI and subsequent light emission in this scintillator.

POST-OPERATIONAL TREATMENT OF RESIDUAL NA COOLLANT IN EBR-2 USING CARBONATION  

SciTech Connect

At the end of 2002, the Experimental Breeder Reactor Two (EBR-II) facility became a U.S. Resource Conservation and Recovery Act (RCRA) permitted site, and the RCRA permit1 compelled further treatment of the residual sodium in order to convert it into a less reactive chemical form and remove the by-products from the facility, so that a state of RCRA 'closure' for the facility may be achieved (42 U.S.C. 6901-6992k, 2002). In response to this regulatory driver, and in recognition of project budgetary and safety constraints, it was decided to treat the residual sodium in the EBR-II primary and secondary sodium systems using a process known as 'carbonation.' In early EBR-II post-operation documentation, this process is also called 'passivation.' In the carbonation process (Sherman and Henslee, 2005), the system containing residual sodium is flushed with humidified carbon dioxide (CO{sub 2}). The water vapor in the flush gas reacts with residual sodium to form sodium hydroxide (NaOH), and the CO{sub 2} in the flush gas reacts with the newly formed NaOH to make sodium bicarbonate (NaHCO{sub 3}). Hydrogen gas (H{sub 2}) is produced as a by-product. The chemical reactions occur at the exposed surface of the residual sodium. The NaHCO{sub 3} layer that forms is porous, and humidified carbon dioxide can penetrate the NaHCO{sub 3} layer to continue reacting residual sodium underneath. The rate of reaction is controlled by the thickness of the NaHCO{sub 3} surface layer, the moisture input rate, and the residual sodium exposed surface area. At the end of carbonation, approximately 780 liters of residual sodium in the EBR-II primary tank ({approx}70% of original inventory), and just under 190 liters of residual sodium in the EBR-II secondary sodium system ({approx}50% of original inventory), were converted into NaHCO{sub 3}. No bare surfaces of residual sodium remained after treatment, and all remaining residual sodium deposits are covered by a layer of NaHCO{sub 3}. From a safety standpoint, the inventory of residual sodium in these systems was greatly reduced by using the carbonation process. From a regulatory standpoint, the process was not able to achieve deactivation of all residual sodium, and other more aggressive measures will be needed if the remaining residual sodium must also be deactivated to meet the requirements of the existing environmental permit. This chapter provides a project history and technical summary of the carbonation of EBR-II residual sodium. Options for future treatment are also discussed.

Heterovalent substitutions in Na2M2TeO6 family: Crystal structure, fast sodium ion conduction and phase transition of Na2LiFeTeO6  

Science Journals Connector (OSTI)

Abstract A new solid electrolyte Na2LiFeTeO6 has been prepared by solid-state reactions in air at 700C and characterized by powder X-ray diffraction, redox titration and impedance measurements on ceramic samples. It is a new superstructure type of the well-known hexagonal layered P2 type with complete ordering of Li, Fe and Te in octahedral brucite-like layers: orthorhombic, P212121, a=5.2109(1), b=8.9791(2), c=11.2389(2), Z=4. At room temperature, sodium ions in the interlayer gap are concentrated in two of the six non-equivalent trigonal prisms; at elevated temperatures, they exhibit high ionic conductivity, e.g., 4S/m at 300C. Orthorhombic distortion decreases on heating, presumably due to sodium movement, and vanishes at ca. 400C giving rise to the hexagonal Na2Co2TeO6-type structure. Analogous Na2LiRTeO6 (R=Al or Ga), Na2LiFeWO6, Na2Mn2TeO6, Na2M2WO6 (M=Ni or Cu), Na2NiMSbO6 (M=Al or Fe) and Na2NiAlTO6 (T=Nb or Ta) could not be prepared.

Photovoltaic mechanism in Na-substituted BiFeO3 films  

Science Journals Connector (OSTI)

Na-substituted BiFeO3 films were prepared on FTO/glass substrates using the solgel method. XRD results showed that all films adopted random orientation and an R3m perovskite structure. UVVis absorption results indicated that the films exhibited intense absorbance around 450nm. The band gaps were 2.59eV, 2.63eV, 2.62eV and 2.52eV for the films substituted with 0%, 5%, 10% and 20% Na, respectively. A substantially enhanced photovoltaic effect was observed in the 20% Na substituted BiFeO3 film; its short-circuit current density was 1.26Acm?2 and the open circuit voltage was ?0.66V. Meanwhile, polarization-modulated Jsc and Voc were observed in the 20% Na substituted BiFeO3 film and the mechanism was studied using the Schottky barrier combined with the ferroelectric polarization model.

Results from DAMA/NaI and perspectives for DAMA/LIBRA  

E-Print Network (OSTI)

The about 100 kg highly radiopure NaI(Tl) set-up of the DAMA project (DAMA/NaI) took data over seven annual cycles up to July 2002 and has achieved results on various rare processes. Its main aim has actually been the exploitation of the model independent WIMP annual modulation signature. After this conference the total exposure, collected during the seven annual cycles, was released. This cumulative exposure (107731 kg day) has given a model independent evidence for the presence of a Dark Matter particle component in the galactic halo at 6.3 sigma C.L.; this main result is summarised here. Some of the many possible corollary model dependent quests for the candidate particle are mentioned. At present, after about five years of new developments, a second generation low background set-up (DAMA/LIBRA with a mass of about 250 kg NaI(Tl)) was built and is taking data since March 2003. New R&D efforts toward a possible NaI(Tl) ton set-up, we proposed in 1996, have been funded and started in 2003.

Enhancement of direct sulfation of limestone by Na2CO3 addition  

Science Journals Connector (OSTI)

For an oxy-fuel circulating fluidized bed combustion system, the limestone calcination is normally prevented due to excessive CO2 partial pressures and the limestone is subject to a direct sulfation reaction. The enhancement of the direct sulfation of limestone by Na2CO3 was investigated under high CO2 partial pressure in a thermogravimetric apparatus (TGA) and scanning electron microscope (SEM) analysis method. A commercial limestone with a mean size of 18.8?m was used. Experimental results indicate that the incorporation of Na+ ions in solid product CaSO4 lattice structures results in formation of more extrinsic point defects in the crystal lattices of CaSO4 and a significantly increased solid-state diffusivity/mobility in the solid product. So the direct sulfation of Na2CO3-doped limestone shows higher rate and higher degree of conversion in the later stage of sulfation, in comparison with the direct sulfation of original limestone. The reaction changes from diffusional control to chemical reaction control in the presence of Na2CO3 because of the effect of foreign ions on accelerating the solid-state diffusion.

In this paper we present results of a long-term observation of the decay of 22Na in the presence of a nuclear fission reactor. The measurements were made outside the containment wall of and underneath the Koeberg nuclear power plant near Cape Town, South Africa. Antineutrino fluxes ranged from ~5*10^11 to 1.6*10^13 cm^-2 s^-1 during this period. We show that the coincidence summing technique provides a sensitive tool to measure a change in the total decay constant as well as the branching ratio between EC and beta+ decay of 22Na to the first excited state in 22Ne. We observe a relative change in count rate between reactor-ON and reactor-OFF equal to (-0.51+/-0.11)*10^-4. After evaluating possible systematic uncertainties we conclude that the effect is either due to a hidden instrumental cause or due to an interaction between antineutrinos and the 22Na nucleus. An upper limit of ~0.03 barn has been deduced for observing any change in the decay rate of 22Na due to antineutrino interactions.

Temperature induced immiscibility in the NaCl?H[subscript 2]O system at high pressure  

SciTech Connect

High-pressure polymorphs of H{sub 2}O are a major component in many outer planets, extra solar bodies, and icy satellites. This study sought to examine the influence of ionic impurities on the phase stability, thermal expansion, and melting curve of ice VII. Powder diffraction patterns of ice VII formed from pure H{sub 2}O and 5 wt.% NaCl aqueous solutions were taken at room temperature up to 11.1 {+-} 0.3 and 26.6 {+-} 0.4 GPa, respectively. Thermal expansions, {alpha}, of all ice VII samples were recorded and modeled up to the melting point of the samples. Ice VII formed from a NaCl-bearing aqueous solution at pressures greater than 2.2 GPa and less than 500 K can be indexed by ice VII only, whereas at temperatures greater than 500 K, diffraction lines indicative of halite (NaCl) are observed and become more intense with increasing temperature and only disappear at the melting point of the high-pressure ice. This phenomenon was observed in all NaCl-bearing ice samples that were heated to greater than 500 K. The melting curves of ice VII formed from pure H{sub 2}O and a 5 wt.% NaCl aqueous solution suggest that the presence of Na{sup +} and Cl{sup -} in the ice VII structure results in a depression of the melting curve by approximately 40 K. The exsolution of halite from the NaCl-doped ice VII and the depression of the ice VII melting curve suggest that the presence of ionic impurities in ice VII may promote the formation of a self-segregating zone deep within ice-rich bodies. This zone could initiate the formation of solute-rich melt pockets that may ascend toward the surface and result in surface manifestations such as solute-bearing aqueous vents, unexplained domes/diapirism, and/or salt-rich regions.

Cleaning residual NaK in the fast flux test facility fuel storage cooling system  

SciTech Connect

The Fast Flux Test Facility (FFTF), located on the U.S. Department of Energy's Hanford Reservation, is a liquid metal-cooled test reactor. The FFTF was constructed to support the U.S. Liquid Metal Fast Breeder Reactor Program. The bulk of the alkali metal (sodium and NaK) has been drained and will be stored onsite prior to final disposition. Residual NaK needed to be removed from the pipes, pumps, heat exchangers, tanks, and vessels in the Fuel Storage Facility (FSF) cooling system. The cooling system was drained in 2004 leaving residual NaK in the pipes and equipment. The estimated residual NaK volume was 76 liters in the storage tank, 1.9 liters in the expansion tank, and 19-39 liters in the heat transfer loop. The residual NaK volume in the remainder of the system was expected to be very small, consisting of films, droplets, and very small pools. The NaK in the FSF Cooling System was not radiologically contaminated. The portions of the cooling system to be cleaned were divided into four groups: 1. The storage tank, filter, pump, and associated piping; 2. The heat exchanger, expansion tank, and associated piping; 3. Argon supply piping; 4. In-vessel heat transfer loop. The cleaning was contracted to Creative Engineers, Inc. (CEI) and they used their superheated steam process to clean the cooling system. It has been concluded that during the modification activities (prior to CEI coming onsite) to prepare the NaK Cooling System for cleaning, tank T-914 was pressurized relative to the In-Vessel NaK Cooler and NaK was pushed from the tank back into the Cooler and that on November 6, 2005, when the gas purge through the In-Vessel NaK Cooler was increased from 141.6 slm to 283.2 slm, NaK was forced from the In-Vessel NaK Cooler and it contacted water in the vent line and/or scrubber. The gases from the reaction then traveled back through the vent line coating the internal surface of the vent line with NaK and NaK reaction products. The hot gases also exited the scrubber through the stack and due to the temperature of the gas, the hydrogen auto ignited when it mixed with the oxygen in the air. There was no damage to equipment, no injuries, and no significant release of hazardous material. Even though the FSF Cooling System is the only system at FFTF that contains residual NaK, there are lessons to be learned from this event that can be applied to future residual sodium removal activities. The lessons learned are: - Before cleaning equipment containing residual alkali metal the volume of alkali metal in the equipment should be minimized to the extent practical. As much as possible, reconfirm the amount and location of the alkali metal immediately prior to cleaning, especially if additional evolutions have been performed or significant time has passed. This is especially true for small diameter pipe (<20.3 centimeters diameter) that is being cleaned in place since gas flow is more likely to move the alkali metal. Potential confirmation methods could include visual inspection (difficult in all-metal systems), nondestructive examination (e.g., ultrasonic measurements) and repeating previous evolutions used to drain the system. Also, expect to find alkali metal in places it would not reasonably be expected to be. - Staff with an intimate knowledge of the plant equipment and the bulk alkali metal draining activities is critical to being able to confirm the amount and locations of the alkali metal residuals and to safely clean the residuals. - Minimize the potential for movement of alkali metal during cleaning or limit the distance and locations into which alkali metal can move. - Recognize that when working with alkali metal reactions, occasional pops and bangs are to be anticipated. - Pre-plan emergency responses to unplanned events to assure responses planned for an operating reactor are appropriate for the deactivation phase.

Investigations to convert CO2, NaCl and H2O into Na2CO3 and \\{HCl\\} by thermal solar energy with high solar efficiency  

Science Journals Connector (OSTI)

Abstract Exhaust CO2, NaCl and H2O can be converted to Na2CO3 and \\{HCl\\} by the MgCl2/MgO modified ammonia soda process at a maximum temperature of 525C. Such a temperature is easily reached by solar troughs. Subsequently this process stores thermal solar energy as chemical energy and concomitantly CO2 can be removed from the environment. The process has been investigated theoretically and experimentally to further enhance its solar efficiency. It is shown theoretically that Mg-compounds are unique for this process and that the MgCl2/MgO modification is optimal. Experiments demonstrate that by splitting the main reaction of this process into two steps the solar efficiency can be enhanced to 21.5% and very highly concentrated \\{HClaq\\} can be obtained. The yield of the main chemical reaction exceeds 95% at 525C. Suggestions are given for an improved thermal solar trough system to perform the main chemical reaction.

Synthesis, structure and properties of new chain cuprates, Na{sub 3}Cu{sub 2}O{sub 4} and Na{sub 8}Cu{sub 5}O{sub 10}

Na{sub 3}Cu{sub 2}O{sub 4} and Na{sub 8}Cu{sub 5}O{sub 10} were prepared via the azide/nitrate route from stoichiometric mixtures of the precursors CuO, NaN{sub 3} and NaNO{sub 3}. Single crystals have been grown by subsequent annealing of the as prepared powders at 500 deg. C for 2000h in silver crucibles, which were sealed in glass ampoules under dried Ar. According to the X-ray analysis of the crystal structures (Na{sub 3}Cu{sub 2}O{sub 4}: P2{sub 1}/n, Z=4, a=5.7046(2), b=11.0591(4), c=8.0261(3)A, {beta}=108.389(1){sup o}, 2516 independent reflections, R{sub 1}(all)=0.0813, wR{sub 2} (all)=0.1223; Na{sub 8}Cu{sub 5}O{sub 10}: Cm, Z=2, a=8.228(1), b=13.929(2), c=5.707(1)A, {beta}=111.718(2){sup o}, 2949 independent reflections, R{sub 1}(all)=0.0349, wR{sub 2} (all)=0.0850), the main feature of both crystal structures are CuO{sub 2} chains built up from planar, edge-sharing CuO{sub 4} squares. From the analysis of the Cu-O bond lengths, the valence states of either +2 or +3 can be unambiguously assigned to each copper atom. In Na{sub 3}Cu{sub 2}O{sub 4} these ions alternate in the chains, in Na{sub 8}Cu{sub 5}O{sub 10} the periodically repeated part consists of five atoms according to Cu{sup II}-Cu{sup II}-Cu{sup III}-Cu{sup II}-Cu{sup III}. The magnetic susceptibilities show the dominance of antiferromagnetic interactions. At high temperatures the compounds exhibit Curie-Weiss behaviour (Na{sub 3}Cu{sub 2}O{sub 4}: {mu}=1.7{mu}{sub B}, {theta}=-160K, Na{sub 8}Cu{sub 5}O{sub 10}: {mu}=1.8{mu}{sub B}, {theta}=-58K, magnetic moments per divalent copper ion). Antiferromagmetic ordering is observed to occur in these compounds below 13K (Na{sub 3}Cu{sub 2}O{sub 4}) and 24K (Na{sub 8}Cu{sub 5}O{sub 10})

Low-energy positron-diffraction study of NaF and LiF  

Science Journals Connector (OSTI)

Using a magnetically transported beam of slow positrons, we have measured the elastic backscattering probability versus energy for positrons normally incident on air-cleaved and vacuum-cleaved (100) surfaces of NaF and LiF. We observe enormous first-order Bragg peaks and several higher-order peaks, the positions of which imply an inner potential of -0.50.2 and -0.10.2 eV for NaF and LiF, respectively. The atomic plane spacings are equal to the bulk values within 1/2%. There are only slight differences between the data obtained using the freshly air-cleaved and the vacuum-cleaved surfaces. Surface disorder may be responsible for the presence of some weak Bragg reflections corresponding to directions that would otherwise be inaccessible to the incident positron beam. The temperature dependence indicates that the disorder would not have a thermal origin.

DALI2: A NaI(Tl) detector array for measurements of $?$ rays from fast nuclei  

E-Print Network (OSTI)

A NaI(Tl) detector array called DALI2 (Detector Array for Low Intensity radiation 2) has been constructed for in-beam $\\gamma$-ray spectroscopy experiments with fast radioactive isotope (RI) beams. It consists typically of 186 NaI(Tl) scintillators covering polar angles from $\\sim$15$^{\\circ}$ to $\\sim$160$^{\\circ}$ with an average angular resolution of 6$^{\\circ}$ in full width at half maximum. Its high granularity (good angular resolution) enables Doppler-shift corrections that result in, for example, 10% energy resolution and 20% full-energy photopeak efficiency for 1-MeV $\\gamma$ rays emitted from fast-moving nuclei (velocities of $v/c \\simeq 0.6$). DALI2 has been employed successfully in numerous experiments using fast RI beams with velocities of $v/c = 0.3 - 0.6$ provided by the RIKEN RI Beam Factory.

Two-photon absorption cross sections of the N1 and F3+ centers in NaF have been determined by means of the luminescence excited by the two-photon absorption. The measured polarization dependence of the process led us to attribute the excitation to the Ag?Ag transition in the N1 center and to the A?E transition in the F3+ center.

The high precision of recent measurements for low-energy {alpha}-particle elastic-scattering as well as induced-reaction data makes possible the understanding of actual limits and possible improvement of the global optical model potentials parameters. Involvement of recent optical potentials for reliable description of both the elastic scattering and emission of {alpha}-particles, of equal interest for nuclear astrophysics (NA) and nuclear technology (NT) for fusion devices, is discussed in the present work.

Evaluation of aqueous Na{sup +}/Cs{sup +} separation by electrodialysis  

SciTech Connect

In support of the Hanford Site cleanup, electrodialysis is being investigated as a method to separate aqueous sodium (Na{sup +}) and cesium (Cs{sup +}) ions. The approach has many advantages over existing separation technologies; in particular, electrodialysis creates little secondary waste while producing usable acid and base streams. The fundamentals of electrodialysis are presented in this report to provide a foundation for interpreting experimental data. A flat-plate laboratory-scale apparatus was used to determine the feasibility of separating Na{sup +}/Cs{sup +} mixtures by electrodialysis. The results showed that Cs{sup +} is preferentially separated over Na{sup +} by a factor of 2 to 3 using a Nafion{reg_sign} 417 cationic membrane. The separation is relatively insensitive to solution ionic strength and flow-rate variations. The current efficiency of the separation ranges from 0.60 to 0.65 depending on the applied voltage. The laboratory-scale system was characterized by dimensional analysis, which demonstrated that the process could be scaled up to a size attractive for the volume of waste at the Hanford Site. Preliminary experiments on a bench-scale system were also conducted. The initial results showed that the current-voltage response of the laboratory- and the bench-scale unit is identical.

Thermal Conductivity of LiF and NaF and the Ziman Limit  

Science Journals Connector (OSTI)

A model calculation of lattice thermal conductivity is presented and applied to measurements on LiF and NaF crystals of high purity. The treatment is in the spirit of a Callaway analysis, but at a somwhat more fundamental level: The Ziman variational principle for thermal conductivity derived from the phonon Boltzmann equation is used, with the phonon distribution function approximated by a displaced Planck part plus another term reducing the deviation from equilibrium for high-frequency phonons. An isotropic Debye approximation for the phonon spectra of LiF and NaF gives a good fit to the conductivity data, with only two semi-adjustable parameters (Grneisen constant and a zone-edge longitudinal phonon frequency) for the anharmonic contribution. The most important feature of the calculation is the failure of the thermal conductivity to approach the Ziman limit of resistanceless phonon-phonon N processes. This is due to the important role played by high-frequency phonons in thermal conduction. Even for an infinite perfect crystal at arbitrarily low temperatures, the Ziman limit underestimates the conductivity by at least 50%. If this prediction is correct, it is not a peculiarity of LiF and NaF alone, and should be of importance for the theory of second-sound propagation in insulators.

Br-Cl-Na systematics in Illinois basin fluids: Constraints on fluid origin and evolution  

SciTech Connect

The authors present here bromide, chloride, and sodium data for fluids from reservoirs of Ordovician through Pennsylvania age in the Illinois basic which suggest that remnant marine fluids contribute significantly to fluid Cl budgets. Cl/Br and NaBr ratios for Ordovician through Devonian formation fluids are relatively uniform and near those for seawater, despite greater than a factor of ten range in Cl concentration. In contrast, fluids from Mississippian and Pennsylvanian reservoirs, separated from older reservoirs by the New Albany Shale Group, have more variable fluid Cl/Br and Na/Br ratios, most of which are significantly greater then those of seawater. The 1:1 stoichiometry of Cl and Na increases for Mississippian and Pennsylvanian formation fluids is consistent with halite dissolution. Nevertheless, Br systematics and mass-balance considerations indicate that he overall Cl budget of Illinois basin formation fluids appears to be more significantly influenced by the contribution from subaerially evaporated seawater than by halite dissolution.

First principles calculations on Na and K-adsorbed diamond(100) surface  

SciTech Connect

Self-consistent, periodic, density functional theory calculations, using PW91 functional, have been performed to investigate Na and K adsorption on the C(100)(2?1) surface. Our calculations showed that Na and K adatoms preferred to occupy valley-bridge sites at the coverage (?) of 0.5ML. For the coverage of 1ML, the combination of pedestal site and valley-bridge site turned out to be energetically favored. These findings are found to be consistent with those obtained for alkali-metal adsorption on silicon and germanium surfaces. Two desorption peaks named ? and ? for K adsorption have been observed and assigned to pedestal or bridge site and valley-bridge sites experimentally, while our results showed that the ? and ? states should be ascribed to pedestal site and valley-bridge sites and the combination of bridge and valley-bridge site is not the local minima. Work function analysis showed that when Na and K are adsorbed on diamond surface, the work function will decrease linearly with increasing coverage, up to a minimum, and finally increase again because of the depolarization of the adsorbate, agreeing well with experiments.

High-temperature corrosion of metallic alloys in an oxidizing atmosphere containing NaCl  

SciTech Connect

A particular heat-exchanger application involved metallic alloys exposed to flue gases of an aluminum remelt furnace. Because the flue gases might contain NaCl and other halides, the corrosion behavior of the alloys was to be investigated. Planned direct exposure of candidate alloys to the flue gases, however, was not conducted because of premature termination of the project. Complementary laboratory testing was conducted on seven commercially available alloys and two nickel aluminides. These materials were exposed to an oxidizing atmosphere containing 0.06 wt % NaCl for 1100 h at 1000/degree/C. Most of the alloy exhibited grain-boundary attack, which resulted in complete oxidation of enveloped grains. The alloys Incoloy MA-956, Incoloy 800, Inconel 625, Inconel 601, Hastelloy X, Haynes 188, and nickel aluminide IC-50 were substantially more corroded than Alloy 214 and nickel aluminide IC-221. The latter two alloys, therefore, would probably be superior to the others in application involving flue gases containing NaCl. Strength fabricability, and weldability, which are briefly discussed, would also affect selection of materials. 8 refs., 12 figs., 5 tabs.

Aluminium alloy based hydrogen storage tank operated with sodium aluminium hexahydride Na3AlH6  

Science Journals Connector (OSTI)

Abstract Here we present the development of an aluminium alloy based hydrogen storage tank, charged with Ti-doped sodium aluminium hexahydride Na3AlH6. This hydride has a theoretical hydrogen storage capacity of 3mass-% and can be operated at lower pressure compared to sodium alanate NaAlH4. The tank was made of aluminium alloy EN AW 6082 T6. The heat transfer was realised through an oil flow in a bayonet heat exchanger, manufactured by extrusion moulding from aluminium alloy EN AW 6060 T6. Na3AlH6 is prepared from 4mol-% TiCl3 doped sodium aluminium tetrahydride NaAlH4 by addition of two moles of sodium hydride NaH in ball milling process. The hydrogen storage tank was filled with 213g of doped Na3AlH6 in dehydrogenated state. Maximum of 3.6g (1.7mass-% of the hydride mass) of hydrogen was released from the hydride at approximately 450K and the same hydrogen mass was consumed at 2.5MPa hydrogenation pressure. 45 cycle tests (rehydrogenation and dehydrogenation) were carried out without any failure of the tank or its components. Operation of the tank under real conditions indicated the possibility for applications with stationary HT-PEM fuel cell systems.

Dispersion relations of surface phonons in LiF(001) and NaF(001)  

Science Journals Connector (OSTI)

Recent atom-scattering experimental data have stimulated a new investigation on the surface phonons of some alkali halides. In the framework of Green's-function method applied to breathing-shell model dynamics we have calculated the dispersion curves and a few K-selected densities of states of surface phonons for the (001) surface of NaF and LiF at room temperature. Particular attention is paid to the change in ion polarizabilities occurring at the surface and its effect on the Rayleigh wave frequencies at the zone boundary.

Carrier Density Enhancement in Semiconducting NaSn and CsPb  

Science Journals Connector (OSTI)

The electrical conductivity ? and thermoelectric power S data have been measured in two semiconductors that undergo a solid-state transformation to a dynamically disordered phase about 100 C below the melting point. At the transition, ? for NaSn is reduced while that for CsPb exhibits a dramatic rise. For both semiconductors, S is reduced in magnitude and changes sign at the transition. These results are consistent with a model which explicitly allows for the interactions between mobile ions and electrons and which provides a unified explanation of the transport properties of these compounds and other fast ion conductors with appreciable electronic conductivity.

Thermonuclear reaction rate of $^{18}$Ne($?$,$p$)$^{21}$Na from Monte-Carlo calculations  

E-Print Network (OSTI)

The $^{18}$Ne($\\alpha$,$p$)$^{21}$Na reaction impacts the break-out from the hot CNO-cycles to the $rp$-process in type I X-ray bursts. We present a revised thermonuclear reaction rate, which is based on the latest experimental data. The new rate is derived from Monte-Carlo calculations, taking into account the uncertainties of all nuclear physics input quantities. In addition, we present the reaction rate uncertainty and probability density versus temperature. Our results are also consistent with estimates obtained using different indirect approaches.

Thermodynamic modeling of neptunium(V)-acetate complexation in concentrated NaCl media  

SciTech Connect

The complexation of neptunium(V), Np(V), with the acetate anion, Ac{sup -}, was measured in sodium chloride media to high concentration using an extraction technique. The data were interpreted using the thermodynamic formalism of Pitzer, which is valid to high electrolyte concentrations. A consistent model for the deprotonation constants of acetic acid in NaCl and NaClO{sub 4} media was developed. For the concentrations of acetate expected in a waste repository, only the neutral complex NpO{sub 2}Ac(aq) was important in describing the interactions between the neptunyl ion and acetate. The thermodynamic stability constant log {beta}{sup 0}{sub 101} for the reaction NpO{sub 2}{sup +} + Ac{sup -} {leftrightarrow} NpO{sub 2}Ac was calculated to be 1.46{plus_minus}0.11. This weak complexing behavior between the neptunyl ion and acetate indicates that acetate will not significantly enhance dissolved Np(V) concentrations in ground waters associated with nuclear waste repositories that may contain acetate.

Electronic Reconstruction through the Structural and Magnetic Transitions in Detwinned NaFeAs  

SciTech Connect

We use angle-resolved photoemission spectroscopy to study twinned and detwinned iron pnictide compound NaFeAs. Distinct signatures of electronic reconstruction are observed to occur at the structural (T{sub S}) and magnetic (T{sub SDW}) transitions. At T{sub S}, C{sub 4} rotational symmetry is broken in the form of an anisotropic shift of the orthogonal d{sub xz} and d{sub yz} bands. The magnitude of this orbital anisotropy rapidly develops to near completion upon approaching T{sub SDW}, at which temperature band folding occurs via the antiferromagnetic ordering wave vector. Interestingly, the anisotropic band shift onsetting at T{sub S} develops in such a way to enhance the nesting conditions in the C{sub 2} symmetric state, hence is intimately correlated with the long range collinear AFM order. Furthermore, the similar behaviors of the electronic reconstruction in NaFeAs and Ba(Fe{sub 1-x}Co{sub x}){sub 2}As{sub 2} suggests that this rapid development of large orbital anisotropy between T{sub S} and T{sub SDW} is likely a general feature of the electronic nematic phase in the iron pnictides, and the associated orbital fluctuations may play an important role in determining the ground state properties.

Synthesis and characterization of the layered iron-selenide Na0.8Fe1.6Se2  

Science Journals Connector (OSTI)

An iron-selenide Na0.8Fe1.6Se2 single crystal has been successfully synthesized using a self-flux method. The electrical resistivity measurement shows that this material exhibits semiconducting behavior in the whole temperature range, with an anomalous increment of resistivity at Ts?595 K. By varying the concentrations of Na and Fe, a small volume of superconducting phase could be achieved with a critical temperature of Tc?34 K. Structural characterization shows that, similarly to K0.8Fe1.6Se2, the Na0.8Fe1.6Se2 phase exhibits clear superstructure with a modulation wave vector of q=(3/5,1/5,0) caused by the Fe-vacancy order within the a-b plane.

Multiple high-temperature transitions driven by dynamical structures in NaI  

SciTech Connect

Multiple, consecutive high-temperature transitions in NaI involving dynamical order and/or localization in the energy-momentum spectrum but not in the average crystal structure are revealed by lattice dynamics, x-ray lattice spacing, and heat capacity measurements. Distinctive energy-momentum patterns and lattice distortions indicate dynamical structures forming within randomly stacked planes, rather than the isolated point-defect-like intrinsic localized modes predicted. Transition entropies are accounted for by vibrational entropy changes and the transition enthalpies are explained by the strain energy of forming stacking-fault-like planar distortions deduced from x-ray diffraction peak shifts. The vibrational entropy of the dynamical structures stabilizes surrounding elastic distortions.

Evidence for threshold effects in positron diffraction from NaF and LiF  

Science Journals Connector (OSTI)

We have measured the energy dependence of the intensity of a positron beam specularly reflected from the (100) surfaces of NaF and LiF. A 1-eV-wide peak located at an energy that decreases with increasing angle of incidence ? is qualitatively identified as a beam threshold effect. Given the known small positron affinity for the solids, the narrowness of the peak is consistent with its being due to a true surface resonance. However, the dispersion appears to depart from the expected energy versus ? trajectory parallel to the kinematic threshold. Additionally, a search in 50-meV steps did not reveal any fine structure in the peaks, possibly due to our 0.3-eV effective instrumental resolution. Further experiments to map the dispersion with greater precision, to measure the binding energies of the resonances, and to search for possible fine structure are proposed.

Total reflection infrared spectroscopy of water-ice and frozen aqueous NaCl solutions  

SciTech Connect

Liquid-like and liquid water at and near the surface of water-ice and frozen aqueous sodium chloride films were observed using attenuated total reflection infrared spectroscopy (ATR-IR). The concentration of NaCl ranged from 0.0001 to 0.01 M and the temperature varied from the melting point of water down to 256 K. The amount of liquid brine at the interface of the frozen films with the germanium ATR crystal increased with salt concentration and temperature. Experimental spectra are compared to reflection spectra calculated for a simplified morphology of a uniform liquid layer between the germanium crystal and the frozen film. This morphology allows for the amount of liquid observed in an experimental spectrum to be converted to the thickness of a homogenous layer with an equivalent amount of liquid. These equivalent thickness ranges from a nanometer for water-ice at 260 K to 170 nm for 0.01 M NaCl close to the melting point. The amounts of brine observed are over an order of magnitude less than the total liquid predicted by equilibrium thermodynamic models, implying that the vast majority of the liquid fraction of frozen solutions may be found in internal inclusions, grain boundaries, and the like. Thus, the amount of liquid and the solutes dissolved in them that are available to react with atmospheric gases on the surfaces of snow and ice are not well described by thermodynamic equilibrium models which assume the liquid phase is located entirely at the surface.

Microstructural and compositional change of NaOH-activated high calcium fly ash by incorporating Na-aluminate and co-existence of geopolymeric gel and C-S-H(I)  

SciTech Connect

This study explores the reaction products of alkali-activated Class C fly ash-based aluminosilicate samples by means of high-resolution synchrotron X-ray diffraction (HSXRD), scanning electron microscope (SEM), and compressive strength tests to investigate how the readily available aluminum affects the reaction. Class C fly ash-based aluminosilicate raw materials were prepared by incorporating Na-aluminate into the original fly ashes, then alkali-activated by 10 M NaOH solution. Incorporating Na-aluminate reduced the compressive strength of samples, with the reduction magnitude relatively constant regardless of length of curing period. The HSXRD provides evidence of the co-existence of C-S-H with geopolymeric gels and strongly suggests that the C-S-H formed in the current system is C-S-H(I). The back-scattered electron images suggest that the C-S-H(I) phase exists as small grains in a finely intermixed form with geopolymeric gels. Despite providing extra source of aluminum, adding Na-aluminate to the mixes did not decrease the Si/Al ratio of the geopolymeric gel.

Charge and Electric Field Fluctuations in Aqueous NaCl Electrolytes  

SciTech Connect

Conventional wisdom concerning crystallization assumes that when NaCl crystallizes from a supersaturated solution, the solvated ions retain their ionic character and simply relocate from their hydration spheres to their most stable positions in the crystal lattice. However, this conventional picture is at odds with observations over 200 years ago reporting the emission of long-lived light resulting from the crystallization of certain salts appropriately referred to as crystalloluminescence. This suggests that electronic structure plays an essential role in crystallization. Strong electric field fluctuations in the gas or condensed phases can drive changes in electronic structure. We have calculated the fluctuation of charge, scalar electric potentials, and vector electric fields for concentrated aqueous NaCl electrolytes. The H2O molecules in the 1st solvation shell of the ions serve as a sink for electron density originating on Cl-. Our analysis reveals that the electric fields inside aqueous electrolytes are extremely large (up to several V/) and thus may alter the ground and excited electronic states in the condensed phase. Furthermore, our analysis shows that the potential and field distributions are largely independent of concentration. We find that the field component distributions to be Gaussian for the ions and non-Gaussian for the O and H sites (computed in the lab frame of reference), however, these non-Gaussian distributions are readily modeled via an orientationally averaged non-zero mean Gaussian plus a zero mean Gaussian. These calculations and analyses provide the first steps toward understanding the magnitude and fluctuations of charge, electric potentials and fields in aqueous electrolytes and what role these fields may play in driving charge redistribution/transfer during crystalloluminescence.

Vacuum ultraviolet reflectivities of LiF, NaF, and KF  

Science Journals Connector (OSTI)

High-resolution normal-incidence (9) reflectivities of lithium-fluoride, sodium-fluoride, and potassium-fluoride single crystals were investigated between 6 and 35 eV at room temperature, 100 and 30 K using a minicomputer-controlled vacuum ultraviolet reflectometer at the Winconsin Synchrotron Radiation Facility. Data were taken on surfaces cleaved and maintained in high vacuum. Reflectivity data were Kramers-Kronig analyzed to yield the dielectric functions of the materials and various energy and temperature derivatives were calculated as an aid to interpretation. In all materials, considerable new structure is reported with broad, general agreement with earlier work on LiF and KF. We report the first reflectivity data between 12 and 35 eV for NaF. Computed values of -Im(1?) were in good agreement with electron-energy-loss experiments of Creuzburg. It is only possible to provide detailed interpretation of optical features in special cases, but a general discussion is provided in the conventional framework.

CO adsorption-desorption properties of cation-exchanged NaX zeolite and supported ruthenium  

SciTech Connect

The binding states of carbon monoxide over cation-exchanged NaX zeolites and over corresponding Ru-containing samples have been investigated using thermal desorption spectroscopy. Exchange of sodium with cations such as Li{sup +}, Ca{sup 2+}, Mg{sup 2+}, and La{sup 3+} gave rise to additional CO adsorption states, a higher isosteric heat of CO adsorption, an increased density of acid sites, and an increased amount of adsorbed CO, depending on the nature and ionic radius of the charge-balancing cation. The charge-balancing cations at the zeolite surface (e.g., Ca{sub 2+}, La{sup 3+}) function as additional CO adsorption sites in conjunction with surface acid centers (e.g., the Al{sup 3+} center) and metal sites. In addition to surface sites, CO is also found to be held in structural cavities and macropores of the zeolite matrix. The programmed heating of both the metal-free and Ru-containing zeolites subsequent to room temperature CO adsorption gave desorption peaks due to release of CO at temperatures less than {approximately}500 K while the higher temperature peaks were constituted mainly of CO{sub 2}. Electron spectroscopy results have revealed that the exposure of these samples to CO and subsequent thermal treatment resulted in the formation of surface carbonaceous species. The nature of CO adsorption states giving rise to CO{sub 2} formation is discussed.

Hydrothermal synthesis and the crystal structure of borate cancrinite (Na,Ca){sub 2}[Na{sub 6}(AlSiO{sub 4}){sub 6}](BO{sub 3}) . 2H{sub 2}O  

SciTech Connect

Transparent prismatic single crystals of borate cancrinite (Na,Ca){sub 2}[Na{sub 6}(AlSiO{sub 4}){sub 6}](BO{sub 3}) . 2H{sub 2}O are prepared through hydrothermal crystallization. The parameters of the hexagonal unit cell and intensities of 10806 reflections are measured on an Enraf-Nonius CAD4 automated diffractometer. The compound crystallizes in the hexagonal crystal system with the unit cell parameters a = 12.745(4) A, c = 5.180(2) A, V = 728.6(4) A{sup 3}, and space group P6{sub 3}. The structure is determined by direct methods and refined using the full-matrix least-squares procedure in the anisotropic approximation for the non-hydrogen atoms. The refinement of the structure is performed to the final discrepancy factor R{sub 1} = 0.027 for 2889 unique reflections with I > 2 {sigma} (I). In the structure of the borate cancrinite, the AlO{sub 4} and SiO{sub 4} tetrahedra form a zeolite-like framework in which twelve-membered hexagonal channels are occupied by sodium atoms and BO{sub 3} groups, whereas six-membered channels are filled with sodium and calcium atoms and water molecules. The mean interatomic distances are found to be as follows: (Si-O){sub mean} = 1.614 A and (Al-O){sub mean} = 1.741 A in the AlO{sub 4} and SiO{sub 4} tetrahedra, (Na-O){sub mean} = 2.542 A in the seven-vertex sodium polyhedra, and [(Na,Ca)-O]{sub mean} = 2.589 A in the ditrigonal bipyramids.

The Na{sup +}/H{sup +} exchanger (NHE) is a family of proteins which exchange Na{sup +} for H{sup +} according to their concentration gradients in an electroneutral manner. The exchanger also plays a key role in several other cellular functions including proliferation, differentiation, apoptosis, migration, and cytoskeletal organization. Since not much is known on the relationship between NHE and diabetes mellitus, this review outlines the contribution of NHE to chronic complications of diabetes mellitus, such as diabetic nephropathy; diabetic cardiomyopathy.

Structure Study of Cellulose Fibers Wet-Spun from Environmentally Friendly NaOH/Urea Aqueous Solutions  

SciTech Connect

In this study, structure changes of regenerated cellulose fibers wet-spun from a cotton linter pulp (degree of polymerization {approx}620) solution in an NaOH/urea solvent under different conditions were investigated by simultaneous synchrotron wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS). WAXD results indicated that the increase in flow rate during spinning produced a better crystal orientation and a higher degree of crystallinity, whereas a 2-fold increase in draw ratio only affected the crystal orientation. When coagulated in a H{sub 2}SO{sub 4}/Na{sub 2}SO{sub 4} aqueous solution at 15 {sup o}C, the regenerated fibers exhibited the highest crystallinity and a crystal orientation comparable to that of commercial rayon fibers by the viscose method. SAXS patterns exhibited a pair of meridional maxima in all regenerated cellulose fibers, indicating the existence of a lamellar structure. A fibrillar superstructure was observed only at higher flow rates (>20 m/min). The conformation of cellulose molecules in NaOH/urea aqueous solution was also investigated by static and dynamic light scattering. It was found that cellulose chains formed aggregates with a radius of gyration, R{sub g}, of about 232 nm and an apparent hydrodynamic radius, R{sub h}, of about 172 nm. The NaOH/urea solvent system is low-cost and environmentally friendly, which may offer an alternative route to replace more hazardous existing methods for the production of regenerated cellulose fibers.

Doping-dependent anisotropic superconducting gap in Na1-?(Fe1-xCox)As from London penetration depth  

SciTech Connect

The London penetration depth was measured in single crystals of self-doped Na1-?FeAs (from under doping to optimal doping, Tc from 14 to 27 K) and electron-doped Na(Fe1-xCox)As with x ranging from undoped, x=0, to overdoped, x=0.1. In all samples, the low-temperature variation of the penetration depth exhibits a power-law dependence, ??(T)=ATn, with the exponent that varies in a domelike fashion from n1.1 in the underdoped, reaching a maximum of n1.9 in the optimally doped, and decreasing again to n1.3 on the overdoped side. While the anisotropy of the gap structure follows a universal domelike evolution, the exponent at optimal doping, n1.9, is lower than in other charge-doped Fe-based superconductors (FeSCs). The full-temperature range superfluid density, ?s(T)=?(0)/?(T)2, at optimal doping is also distinctly different from other charge-doped FeSCs but is similar to isovalently substituted BaFe2(As1-xPx)2, believed to be a nodal pnictide at optimal doping. These results suggest that the superconducting gap in Na(Fe1-xCox)As is highly anisotropic even at optimal doping.

Na-Cl-Br systematics of fluid inclusions from Mississippi Valley-type deposits, Appalachian Basin: Constraints on solute origin and migration paths  

SciTech Connect

This study evaluated Na-Cl-Br systematics of fluid inclusion-hosted brines in Mississippi Valley-type (MVT) deposits from the Appalachian Basin. Unlike other geochemical tracers such as lead and strontium isotopes which constrain metal sources, Na-Cl-Br systematics identify sources of brine salinity. Saline formation waters can vary systematically within and between basins with regard to their Na-Cl-Br compositions depending on the importance of halite dissolution relative to retention of subaerially evaporated seawater for the halogen budget. Oil field brine compositions from the Illinois and Appalachian basins are quite distinct in their Na-Cl-Br systematics. Compositions of saline fluid inclusions in MVT deposits generally are consistent with these regional differences. These results shed new light on the extent of regional flow systems and on the geochemical evolution of saline fluids responsible for mineralization. Nearly all fluid inclusions analyzed from the Appalachian MVT deposits have Na/Br and Cl/Br ratios less than modern seawater, consistent with ratios observed in marine brines involved in halite precipitation. The Na-Cl-Br systematics of the brines responsible for Appalachian MVT deposits may be inherited from original marine brines refluxed into the porous carbonate shelf sediments that host these deposits. The Cl/Br and Na/Br ratios of most fluid inclusion-hosted brines from Appalachian MVT sphalerites and fluorites fall into two compositional groups, one from the Lower Cambrian paleoaquifer and another from the Lower Ordovician paleoaquifer. Leachates from most MVT barite deposits form a third compositional group having lower Na/Br and Cl/Br ratios than the other two. Appalachian MVT leachate compositions differ significantly from those in MVT deposits in the Cincinnati arch-midcontinent region suggesting that these two MVT provinces formed from brines of different origin or flow path. 59 refs., 8 figs., 2 tabs.

Electron spin resonance and electron spin-echo modulation study of paramagnetic Rh species generated in Ca-Y and Na-Y zeolites  

SciTech Connect

Paramagnetic Rh species generated in RhNa-Y and RhCa-Y zeolites after various treatments were characterized by using electron spin resonance (ESR) and electron spin-echo modulation (ESEM) spectroscopies. Activation in flowing oxygen at 500/sup 0/C ..beta..-hydrogen a considerable amount of Rh(II) located in site I in the hexagonal prism of the zeolite structure for 3 wt % Rh in RhNa-Y zeolite. Samples of 1 wt % Rh in RhNa-Y and RhCa-Y did not show any paramagnetic signals. Adsorption of various adsorbates such as water, ammonia, methanol, carbon monoxide, and oxygen on activated samples induced a considerable increase in the ESR intensities. Adsorption of oxygen and carbon monoxide yields the corresponding adducts which are located in the ..cap alpha..-cage of the zeolite structure. Hydration generated a species which is coordinated to three water molecules. Adsorption of methanol on RhNa-Y generated a species H2 which is also formed after reduction of RhNa-Y with H/sub 2/, suggesting that the methanol molecule undergoes a reaction to generate products which further reduce Rh(III) species in the ..beta..-cage of the zeolite structure to Rh(II). No significant differences were observed between RhNa-Y and RhCa-Y except for the formation of different Rh(II) species after methanol adsorption in RhCa-Y and the generation of a larger amount of Rh(II) in site I in RhNa-Y. These results are compared to previously obtained data in RhNa-X and RhCa-X to account for the effect of the cocations and the Si/Al ratio on the generation of Rh(II) species in zeolites.

Quantitative Trait Loci Affecting Milk Yield and Protein Percentage in a Three-Country Brown Swiss Population  

Science Journals Connector (OSTI)

Quantitative trait loci (QTL) mapping projects have been implemented mainly in the Holstein dairy cattle breed for several traits. The aim of this study is to map QTL for milk yield (MY) and milk protein percent (PP) in the Brown Swiss cattle populations of Austria, Germany, and Italy, considered in this study as a single population. A selective DNA pooling approach using milk samples was applied to map QTL in 10 paternal half-sib daughter families with offspring spanning from 1,000 to 3,600 individuals per family. Three families were sampled in Germany, 3 in Italy, 1 in Austria and 3 jointly in Austria and Italy. The pools comprised the 200 highest and 200 lowest performing daughters, ranked by dam-corrected estimated breeding value for each sire-trait combination. For each tail, 2 independent pools, each of 100 randomly chosen daughters, were constructed. Sire marker allele frequencies were obtained by densitometry and shadow correction analyses of 172 genome-wide allocated autosomal markers. Particular emphasis was placed on Bos taurus chromosomes 3, 6, 14, and 20. Marker association for MY and PP with a 10% false discovery rate resulted in nominal P-values of 0.071 and 0.073 for MY and PP, respectively. Sire marker association tested at a 20% false discovery rate (within significant markers) yielded nominal P-values of 0.031 and 0.036 for MY and PP, respectively. There were a total of 36 significant markers for MY, 33 for PP, and 24 for both traits; 75 markers were not significant for any of the traits. Of the 43 QTL regions found in the present study, 10 affected PP only, 8 affected MY only, and 25 affected MY and PP. Remarkably, all 8 QTL regions that affected only MY in the Brown Swiss, also affected MY in research reported in 3 Web-based QTL maps used for comparison with the findings of this study (http://www.vetsci.usyd.edu.au/reprogen/QTL_Map/; http://www.animalgenome.org/QTLdb/cattle.html; http://bovineqtl.tamu.edu/). Similarly, all 10 QTL regions in the Brown Swiss that affected PP only, affected only PP in the databases. Thus, many QTL appear to be common to Brown Swiss and other breeds in the databases (mainly Holstein), and an appreciable fraction of QTL appears to affect MY or PP primarily or exclusively, with little or no effect on the other trait. Although QTL information available today in the Brown Swiss population can be utilized only in a within family marker-assisted selection approach, knowledge of QTL segregating in the whole population should boost gene identification and ultimately the implementation and efficiency of an individual genomic program.

Design Study of Pb-Bi-Cooled and NaK-Cooled Small Reactors: PBWFR and DSFR  

SciTech Connect

The liquid lead-bismuth eutectic (Pb-Bi) has good compatibility with water, which is different from sodium. It is expected that the Pb-Bi could be used as a coolant of the deep sea fast reactor (DSFR) and the Pb-Bi- cooled direct contact boiling water small fast reactor (PBWFR). Physics analysis of the Pb-Bi-cooled small reactor cores with and without inner control rods was performed using the computer program of General Purpose Neutronics Code System (SRAC95) developed by Japan Atomic Energy Research Institute (JAERI). The coolant of Pb-Bi seems to be good as well as NaK for small reactors. (authors)

Emission of Band-Gap-Energy Positrons from Surfaces of LiF, NaF, and Other Ionic Crystals  

Science Journals Connector (OSTI)

Energetic positrons implanted into various ionic crystal surfaces are reemitted with a maximum kinetic energy (14.7 0.7 eV for LiF) near the band-gap energy. The evidence suggests that, at least for LiF and NaF, the emission originates from bulk-formed positronium (Ps) breaking up after diffusing to the surface. In our model, the positrons are Auger emitted when the Ps electrons recombine with holes at the surface, and the spectrum of positron energies thus reflects the density of empty surface states.

Analysis of the 40K contamination in NaI(Tl) crystals from different providers in the frame of the ANAIS project  

E-Print Network (OSTI)

NaI(Tl) large crystals are applied in the search for galactic dark matter particles through their elastic scattering off the target nuclei in the detector by measuring the scintillation signal produced. However, energies deposited in the form of nuclear recoils are small, which added to the low efficiency to convert that energy into scintillation, makes that events at or very near the energy threshold, attributed either to radioactive backgrounds or to spurious noise (non-bulk NaI(Tl) scintillation events), can compromise the sensitivity goals of such an experiment. DAMA/LIBRA experiment, using 250 kg NaI(Tl) target, reported first evidence of the presence of an annual modulation in the detection rate compatible with that expected for a dark matter signal just in the region below 6 keVee (electron equivalent energy). In the frame of the ANAIS (Annual modulation with NaI Scintillators) dark matter search project a large and long effort has been carried out in order to understand the origin of events at very low energy in large sodium iodide detectors and develop convenient filters to reject those non attributable to scintillation in the bulk NaI(Tl) crystal. 40K is probably the most relevant radioactive contaminant in the bulk for NaI(Tl) detectors because of its important contribution to the background at very low energy. ANAIS goal is to achieve levels at or below 20 ppb natural potassium. In this paper we will report on our effort to determine the 40K contamination in several NaI(Tl) crystals, by measuring in coincidence between two (or more) of them. Results obtained for the 40K content of crystals from different providers will be compared and prospects of the ANAIS dark matter search experiment will be briefly reviewed.

Direct measurement of the spin gap in a quasi-one-dimensional clinopyroxene: NaTiSi2O6  

Science Journals Connector (OSTI)

True inorganic spin-Peierls materials are extremely rare, but NaTiSi2O6 was at one time considered to be an ideal candidate owing to its well separated chains of edge-sharing TiO6 octahedra. At low temperatures, this material undergoes a phase transition from C2/c to P1 symmetry, where Ti3+?Ti3+ dimers begin to form within the chains. However, it was quickly realized with magnetic susceptibility that simple spin fluctuations do not progress to the point of enabling such a transition. Since then, considerable experimental and theoretical endeavors have been undertaken to find the true ground state of this system and explain how it manifests. Here, we employ the use of x-ray diffraction, neutron spectroscopy, and magnetic susceptibility to directly and simultaneously measure the symmetry loss, spin singlet-triplet gap, and phonon modes. A gap of 53(3) meV was observed, fit to the magnetic susceptibility, and compared to previous theoretical models to unambiguously assign NaTiSi2O6 as having an orbital-assisted Peierls ground state.

Effects of curing temperature and NaOH addition on hydration and strength development of clinker-free CKD-fly ash binders  

SciTech Connect

Effects of curing temperature and NaOH addition on hydration and strength development of cement kiln dust (CKD)-fly ash (FA) binders were investigated. Pastes made with 50% CKD and 50% FA, having 0, 2, and 5% NaOH addition, and cured at temperatures of 24, 38, and 50 deg. C were evaluated. The hydration products of the binders were examined by thermogravimetric analysis (TGA) and X-ray diffraction (XRD) tests. The results indicate that the major crystalline hydration product of the CKD-FA binders is ettringite, and the ettringite is stable in the CKD-FA system at age over 100 days. Curing at elevated temperature is more effective for CKD-FA binder strength improvement than NaOH addition, the later often depressing ettringite formation in a CKD-FA system. At a proper curing temperature (38 deg. C), addition of a small amount of NaOH (2%) may increase CKD-FA binder strength; while at a high curing temperature (50 deg. C), addition of NaOH (2%) may reduce the binder strength.

Experimental Determinations of the Activity-Composition Relations and Phase Equilibria of H{sub 2}O-CO{sub 2}-NaCl Fluids  

SciTech Connect

An understanding of activity-composition (a/X) relations and phase equilibria for halite-bearing, mixed-species supercritical fluids is critically important in many geological and industrial applications. The authors have performed experiments on the a/X relations and phase equilibria of H{sub 2}O-CO{sub 2}-NaCl fluids at 5OO C, 500 bars, to obtain highly accurate and precise data for this ternary system. H{sub 2}O-CO{sub 2}-NaCl samples were reacted at a (H{sub 2}O) = 0.350, 0.425, 0.437, 0.448, 0.560, 0.606, 0.678, 0.798, and 0.841. Results indicate that fluids with these activities lie in the vapor-NaCl two-phase region, and that a fluid with the last value has a composition close to the three-phase (vapor + brine + halite) field. Data from these experiments and NaCl solubility runs also suggest that the vapor comer of the three-phase field lies near X(H{sub 2}O) = 0.760, X(NaCl) = 0.065, which is a significantly more water-rich composition than suggested by the model of [1].

Phase equilibria in the system H{sub 2}O-NaCl-KCl-MgCl{sub 2} relevant to salt cake processing  

SciTech Connect

One waste product in recycling of Al is salt cake, a mixture of Al, salts, and residue oxides. Several methods have been proposed to recycle salt cake, one involving high-temperature leaching of salts from the salt cake. The salt composition can be approximated as a mixture predominantly of NaCl and KCl salts, with lesser amounts of Mg chloride. In order to better assess the feasibility of recycling salt cake, an experimental study was conducted of phase equilibria in the system H{sub 2}O-NaCl-KCl-MgCl{sub 2} at pressure (P), temperature (T), and composition conditions appropriate for high- temperature salt cake recycling. These experiments were designed to evaluate the effect of small amounts (2-10 wt%) of MgCl{sub 2} on solubilities of halite (NaCl) and sylvite (KCl) in saturated solutions (30-50 wt% NaCl+KCl; NaCl:KCl = 1:1 and 3:1) at elevated P and T.

Exotic magnetism on the quasi-FCC lattices of the d3 double perovskites La2NaB'O6 (B' = Ru, Os)  

SciTech Connect

We find evidence for long-range and short-range ($\\zeta$~$=$~70~\\AA~at 4~K) incommensurate magnetic order on the quasi-face-centered-cubic (FCC) lattices of the monoclinic double perovskites La$_2$NaRuO$_6$ and La$_2$NaOsO$_6$ respectively. Incommensurate magnetic order on the FCC lattice has not been predicted by mean field theory, but may arise via a delicate balance of inequivalent nearest neighbour and next nearest neighbour exchange interactions. In the Ru system with long-range order, inelastic neutron scattering also reveals a spin gap $\\Delta$~$\\sim$~2.75~meV. Magnetic anisotropy is generally minimized in the more familiar octahedrally-coordinated $3d^3$ systems, so the large gap observed for La$_2$NaRuO$_6$ may result from the significantly enhanced value of spin-orbit coupling in this $4d^3$ material.

The reaction mechanism of SnSb and Sb thin film anodes for Na-ion batteries studied by X-ray diffraction, 119Sn and 121Sb M ssbauer spectroscopies  

SciTech Connect

The electrochemical reaction of Sb and SnSb anode materials with Na results in the formation of amorphous materials. To understand the resulting phases and electrochemical capacities we studied the reaction products local order using 119Sn and 121Sb M ssbauer spectroscopies in conjunction with measurements performed on model powder compounds of Na-Sn and Na-Sb to further clarify the reactions steps. For pure Sb the discharge (sodiation) starts with the formation of an amorphous phase composed of atomic environments similar to those found in NaSb, and proceeds further by the formation of environments similar to that present in Na3Sb. The reversible reaction takes place during a large portion of the charge process. At full charge the anode material still contains a substantial fraction of Na, which explains the lack of recrystallization into crystalline Sb. The reaction of SnSb yields Na3Sb crystalline phase at full discharge at higher temperatures (65 and 95 C) while the room temperature reaction yields amorphous compounds. The electrochemically-driven, solid-state amorphization reaction occurring at room temperature is governed by the simultaneous formation of Na-coordinated Sn and Sb environments, as monitored by the decrease (increase) of the 119Sn (121Sb) M ssbauer isomer shifts. Overall, the monitoring of the hyperfine parameters enables to correlate the changes in Na content to the individual Sn and Sb local chemical environments.

The Role of FeS in Initial Activation and Performance Degradation of Na-NiCl2 Batteries  

SciTech Connect

The role of iron sulfide (FeS) in initial cell activation and degradation in the Na-NiCl2 battery was investigated in this work. The research focused on identifying the effects of the FeS level on the electrochemical performance and morphological changes in the cathode. The x-ray photoelectron spectroscopy study along with battery tests revealed that FeS plays a critical role in initial battery activation by removing passivation layers on Ni particles. It was also found that the optimum level of FeS in the cathode resulted in minimum Ni particle growth and improved battery cycling performance. The results of electrochemical characterization indicated that sulfur species generated in situ during initial charging, such as polysulfide and sulfur, are responsible for removing the passivation layer. Consequently, the cells containing elemental sulfur in the cathode exhibited similar electrochemical behavior during initial charging compared to that of the cells containing FeS.

Variations in K{sup +}-Na{sup +} ion exchange depth in commercial and experimental float glass compositions  

SciTech Connect

The authors report the results of ion-exchange experiments conducted on 17 commercial soda-lime-silicate (SLS) float glass and 8 experimental SLS glass compositions. A significant variation in the depth of K{sup +} penetration with relatively small changes in composition was observed. The data were fit to a multiple regression model in which the major oxides are the independent variables and depth of K{sup +} is the dependent variable. The model indicates that increased depth of exchange (increased interdiffusion coefficient) correlates predominantly with increased K{sub 2}O and/or Na{sub 2}O content of the glass, with a decreased total alkaline earth content and with the ratio of CaO/MgO.

Analysis of Na and Ba in an atomic fluorescence method with excitation by a pulsed dye laser with lamp pumping  

SciTech Connect

Among the laser methods used in atomic spectroscopy, atomic fluorescence resonance spectroscopy together with an atomic ionization technique make it possible to work with individual atoms. This paper reports on the determination of Na and Ba in aqueous solutions of their salts with atomic fluorescence analysis performed wih a dye laser and lamp pumping, the pulse of generation having a length of 1-2 usec. The detection limit of elements in atomic fluorescence analysis performed wih dye lasers with lamp pumping can be reduced by increasing the spectral density of the laser radiation through narrowing the line of generation, by employing other dyes to excite lines of greater intensity, by improving the recording system of the fluorescence spectra, and by improving the atomization of the samples to be analyzed.

Coherent neutrino-nucleus scattering detection with a CsI[Na] scintillator at the SNS spallation source  

E-Print Network (OSTI)

We study the possibility of using CsI[Na] scintillators as an advantageous target for the detection of coherent elastic neutrino-nucleus scattering (CENNS), using the neutrino emissions from the SNS spallation source at Oak Ridge National Laboratory. The response of this material to low-energy nuclear recoils like those expected from this process is characterized. Backgrounds are studied using a 2 kg low-background prototype crystal in a dedicated radiation shield. The conclusion is that a planned 14 kg detector should measure approximately 550 CENNS events per year above a demonstrated $\\sim7$ keVnr low-energy threshold, with a signal-to-background ratio sufficient for a first measurement of the CENNS cross-section.

Modulated magnetic structure in quasi-one-dimensional clinopyroxene NaFeGe{sub 2}O{sub 6}  

SciTech Connect

The magnetic structure of the NaFeGe{sub 2}O{sub 6} monoclinic compound has been experimentally investigated using the elastic scattering of neutrons. At a temperature of 1.6 K, an incommensurate magnetic structure has been observed in the form of an antiferromagnetic helix formed by a pairs of the spins of the Fe{sup 3+} ions with helical modulation in the ac plane of the crystal lattice. The wave vector of the magnetic structure has been determined and its temperature behavior has been studied. The analysis of the temperature dependences of the specific heat and susceptibility, as well as the isotherms of the field dependence of the magnetization, has revealed the existence of not only the order-disorder magnetic phase transition at the point T{sub N} = 13 K, but also an additional magnetic phase transition at the point T{sub c} = 11.5 K, which is assumingly an orientation phase transition.

'Devil's Staircase'-Type Phase Transition in NaV{sub 2}O{sub 5} under High Pressure  

SciTech Connect

The 'devil's staircase'-type phase transition in the quarter-filled spin-ladder compound NaV{sub 2}O {sub 5} has been discovered at low temperature and high pressure by synchrotron radiation x-ray diffraction. A large number of transitions are found to successively take place among higher-order commensurate phases with 2a x 2b x zc type superstructures. The observed temperature and pressure dependence of modulation wave number q{sub c}, defined by 1/z, is well reproduced by the axial next nearest neighbor Ising model. The q{sub c} is suggested to reflect atomic displacements presumably coupled with charge ordering in this system.

Steam reforming of methane using double-walled reformer tubes containing high-temperature thermal storage Na2CO3/MgO composites for solar fuel production  

Science Journals Connector (OSTI)

Abstract Double-walled reactor tubes containing thermal storage materials based on the molten carbonate salts100wt% Na2CO3 molten salt, 90wt% Na2CO3/10wt% MgO and 80wt% Na2CO3/20wt% MgO composite materialswere studied for the performances of the reactor during the heat charging mode, while those of methane reforming with steam during heat discharging mode for solar steam reforming. The variations in the temperatures of the catalyst and storage material, methane conversion, duration of reforming for obtaining high levels of methane conversion (>90%), higher heating value (HHV) power of reformed gas and efficiency of the reactor tubes were evaluated for the double-walled reactor tubes and a single-wall reactor tube without the thermal storage. The results for the heat charging mode indicated that the composite thermal storage could successfully store the heat transferred from the exterior wall of the reactor in comparison to the pure molten-salt. The double-walled reactor tubes with the 90wt% Na2CO3/10wt% MgO composite material was the most desirable for steam reforming of methane to realize large HHV amounts of reformed gas and higher efficiencies during heat-discharging mode.

A new study of the $^{22}$Ne(p,$?$)$^{23}$Na reaction deep underground: Feasibility, setup, and first observation of the 186 keV resonance  

E-Print Network (OSTI)

The $^{22}$Ne(p,$\\gamma$)$^{23}$Na reaction takes part in the neon-sodium cycle of hydrogen burning. This cycle is active in asymptotic giant branch stars as well as in novae and contributes to the nucleosythesis of neon and sodium isotopes. In order to reduce the uncertainties in the predicted nucleosynthesis yields, new experimental efforts to measure the $^{22}$Ne(p,$\\gamma$)$^{23}$Na cross section directly at the astrophysically relevant energies are needed. In the present work, a feasibility study for a $^{22}$Ne(p,$\\gamma$)$^{23}$Na experiment at the Laboratory for Underground Nuclear Astrophysics (LUNA) 400\\,kV accelerator deep underground in the Gran Sasso laboratory, Italy, is reported. The ion beam induced $\\gamma$-ray background has been studied. The feasibility study led to the first observation of the $E_{\\rm p}$ = 186\\,keV resonance in a direct experiment. An experimental lower limit of 0.12\\,$\\times$\\,10$^{-6}$\\,eV has been obtained for the resonance strength. Informed by the feasibility study, a dedicated experimental setup for the $^{22}$Ne(p,$\\gamma$)$^{23}$Na experiment has been developed. The new setup has been characterized by a study of the temperature and pressure profiles. The beam heating effect that reduces the effective neon gas density due to the heating by the incident proton beam has been studied using the resonance scan technique, and the size of this effect has been determined for a neon gas target.

A thermodynamic model for calculating nitrogen solubility, gas phase composition and density of the N2H2ONaCl system  

Science Journals Connector (OSTI)

A thermodynamic model is presented to calculate N2 solubility in pure water (273590K and 1600bar) and aqueous NaCl solutions (273400K, 1600bar and 06molkg?1) with or close to experimental accuracy. This model is based on a semi-empirical equation used to calculate gas phase composition of the H2ON2 system and a specific particle interaction theory for liquid phase. With the parameters evaluated from N2H2ONaCl system and using a simple approach, the model is extended to predict the N2 solubility in seawater accurately. Liquid phase density of N2H2ONaCl system at phase equilibrium and the homogenization pressure of fluid inclusions containing N2H2ONaCl can be calculated from this model. A computer code is developed for this model and can be downloaded from the website: www.geochem-model.org/programs.htm.

Early-type stars observed in the ESO UVES Paranal Observatory Project: I -- Interstellar Na I UV, Ti II and Ca II K observations

We present an analysis of interstellar Na I (lambda=3302.37\\AA, 3302.98\\AA), Ti II (lambda=3383.76\\AA) and Ca II K (lambda=3933.66\\AA) absorption features for 74 sightlines towards O- and B-type stars in the Galactic disc. The data were obtained from the UVES Paranal Observatory Project, at a spectral resolution of 3.75km/s and with mean signal to noise ratios per pixel of 260, 300 and 430 for the Na I, Ti II and Ca II observations, respectively. Interstellar features were detected in all but one of the Ti II sightlines and all of the Ca II sightlines. The dependence of the column density of these three species with distance, height relative to the Galactic plane, H I column density, reddening and depletion relative to the solar abundance has been investigated. We also examine the accuracy of using the Na I column density as an indicator of that for H I. In general we find similar strong correlations for both Ti and Ca, and weaker correlations for Na. Our results confirm the general belief that Ti and Ca occur in the same regions of the interstellar medium and also that the Ti II/Ca II ratio is constant over all parameters. We hence conclude that the absorption properties of Ti and Ca are essentially constant under the general interstellar medium conditions of the Galactic disc.

Groundwater remediation by anionic surfactant micelles An innovative double layer model applied to Na+ and Mg2+ association with dodecylsulfate micelles  

Science Journals Connector (OSTI)

The association reactions involving counterions, Na+ and Mg2+, and micelles composed of the anionic surfactant, dodecylsulfate (DS?), were investigated in ultrafiltration experiments. To access the data, an innovative model was developed that considered specific counterion binding within a Stern layer, with binding constant dependent upon the electrical potential as derived by the Poisson-Boltzmann equation and with calculation of the cmc as a function of counterion binding (or association). The experimental and model results both show that magnitude of counterion binding is greater for divalent species, Mg2+, than that for the monovalent species, Na2+. However, high concentration of Na+ compete for surface area diminishing the ability of the DS? to bind either divalent species. At experimental conditions from 0 to 100 mM NaCI addition, the binding ratio (BR) varied only from 0.58 to 0.63. The optimum binding constants, \\{KMg\\} and KNa, were determined to be 0.4 and 1.0 L mol?1, respectively, for the model. The experimental data and model calculated results were generally in good agreement.

ECO2N: A TOUGH2 Fluid Property Module for Mixtures of Water, NaCl,and CO2  

SciTech Connect

ECO2N is a fluid property module for the TOUGH2 simulator (Version 2.0) that was designed for applications to geologic sequestration of CO{sub 2} in saline aquifers. It includes a comprehensive description of the thermodynamics and thermophysical properties of H{sub 2}O-NaCl-CO{sub 2} mixtures, that reproduces fluid properties largely within experimental error for the temperature, pressure and salinity conditions of interest (10 C {le} T {le} 110 C; P {le} 476 bar; salinity up to full halite saturation). Flow processes can be modeled isothermally or non-isothermally, and phase conditions represented may include a single (aqueous or CO{sub 2}-rich) phase, as well as two-phase mixtures. Fluid phases may appear or disappear in the course of a simulation, and solid salt may precipitate or dissolve. This report gives technical specifications of ECO2N and includes instructions for preparing input data. Code applications are illustrated by means of several sample problems, including problems that had been previously investigated in a code intercomparison study.

Laboratory Test Report for Fujitsu 12RLS and Mitsubishi FE12NA Mini-Split Heat Pumps  

SciTech Connect

Mini-split heat pumps are being proposed as a new retrofit option to replace resistance heating in the Pacific Northwest. NREL has previously developed a field test protocol for mini-split systems to ensure consistent results from field tests. This report focuses on the development of detailed system performance maps for mini-split heat pumps so that the potential benefits of mini-split systems can be accurately analyzed for different climate regions and housing types. This report presents laboratory test results for two mini-split heat pumps. Steady-state heating and cooling performance for the Fujitsu 12RLS and Mitsubishi FE12NA was tested under a wide range of outdoor and indoor temperatures at various compressor and fan speeds. Cycling performance for each unit was also tested under both modes of operation. Both systems performed quite well under low loads and the experimental test data aligned with manufacturer reported values. Adequate datasets were attained to promote performance modeling of these two systems in the future.

Band-structure calculations for Ba6Ge25 and Ba4Na2Ge25 clathrates  

Science Journals Connector (OSTI)

Electronic band structures for Ba6Ge25 and Ba4Na2Ge25 clathrates are calculated using linear muffin-tin orbital method within the local-density approximation. It is found that barium states strongly contribute to the density of states at the Fermi level and thus can influence the transport properties of the compounds. A sharp peak of the density of states is found just at the Fermi level. It is also shown that the shifting of barium atoms toward experimentally deduced split positions in Ba6Ge25 produces a splitting of this peak which may be interpreted as a band Jahn-Teller effect. If the locking of the barium atoms at the observed structural phase transition is assumed, this reduction of the density of states at the Fermi level can account for the experimentally observed decrease of the magnetic susceptibility and electrical resistivity at the phase transition, and the values of density of states are in agreement with low-temperature specific-heat measurements and variation of superconducting transition temperature with pressure.

The generation of HCl in the system NaCl-KCl-H{sub 2}O-quartz at 600{degrees}C: Implications regarding HCl in natural systems at lower temperatures  

SciTech Connect

In experiments at 600C in the system NaCI-KCI-H2O, within the analytical uncertainty, stoichiometric quantities of Cl and total alkali metals (Na+K) appear to dissolve in steam coexisting with chloride-rich brine at high pressures in the absence of solid salt. In contrast, at lower pressures, where steam coexists with precipitated salts, significant excess chloride as associated hydrogen chloride (HCI) dissolves in steam. The HCI appears to be generated by the reaction of solid NaCl(s) (halite) with steam, producing solid NaOH(s) that diffuses into halite, forming a solid solution. Where HCI is present highly associated NaOH as well as associated NaCI appear to dissolve in steam, and the solubility of each is increased as the mole fraction of NaOH(s) in halite increases. In our quasi-static experiments, compared to dynamic flow-through experiments of others, higher initial ratios of H2O/NaCI have resulted in higher mole fractions of NaOH(s) in solid solution in halite and, accordingly, higher solubilities of NaCI" and NaOH" dissolved in steam. Addition of quartz to the system NaCI-KCI-H2O results in the formation of sodium disilicate by reaction of silica with NaOH(s) and an order of magnitude increase in the concentration of HCl dissolved in steam. In natural hydrothermal systems at lower temperatures where brine or brine plus steam are present in the absence of precipitated salt, the pH of the brine is controlled mainly by base exchange reactions involving a variety of silicates that fix Na+/H+ and K+/H+ activity ratios. Where feldspars are present pH values generally are near neutral. Where mica, but no feldspar is present pH values may become only moderately acid. High acidity in salt-absent brine systems occurs only where all feldspars and mica have been altered to other minerals (generally pyrophyllite/ kaolinite or alunite). The situation changes significantly when salt precipitates. Hydrolysis produces HCI by the reaction of water with NaCl when halite is present. The NaOH(s) that is produced as a byproduct is likely to react with quartz plus various alumino-silicates, producing a variety of alteration products and allowing steam to become greatly enriched in HCl compared to the composition of steam that is attained in the simple system NaCI-KCI-H2O with halite present. Also, when a natural high-temperature hydrothermal system changes from one in which the pore fluid is brine to one in which the pore fluid is dry steam there is a drastic change in Na+/H+ and K+/H+ activity ratios in the pore fluid because the hydrogen ions that were predominantly dissociated species in the brine become predominantly associated species in steam. The net result is the stabilization of alkali feldspars in contact with steam that may contain appreciable HCI that is produced by the reaction of precipitated salt with the steam.

Influence of spraying parameters on the electrochemical behaviour of HVOF thermally sprayed stainless steel coatings in 3.4% NaCl  

Science Journals Connector (OSTI)

Stainless steel coatings obtained by High Velocity Oxygen Fuel (HVOF) were characterized using optical (OM) and scanning electron microscopy (SEM), electron probe micro-analysis, X-ray diffraction (XRD), open-circuit potential (EOC) measurements, electrochemical impedance spectroscopy (EIS) and polarisation tests. Differences among coated steels were mainly related with the gun-substrate distance parameter (310 mm for samples A and B and 260 mm for C and D). The open-circuit potential values measured for all the samples after 18 h of immersion in aerated and unstirred 3.4% NaCl solution were: ?0.334, ?0.360, ?0.379 and ?0.412 V vs. Ag/AgCl,KClsat. for samples A to D, respectively. For EIS measurements, Nyquist plots showed higher capacitive semi-circle for samples sprayed at longer distance, indicating higher corrosion resistance in NaCl solution.

The role of UV illumination on the initial atmospheric corrosion of 09CuPCrNi weathering steel in the presence of NaCl particles  

Science Journals Connector (OSTI)

Abstract Effect of UV illumination on the NaCl-induced atmospheric corrosion of 09CuPCrNi weathering steel (WS) was qualitatively and quantitatively studied in this work. UV illumination strongly affects the NaCl-induced atmospheric corrosion process of 09CuPCrNi WS mainly through the photovoltaic effect of the corrosion products with semiconductor properties. The photogenerated electrons and holes can directly participate in the cathodic and anodic reactions and thus directly affect the atmospheric corrosion rate of 09CuPCrNi WS. Meanwhile, the photogenerated electrons and holes can directly involve in the corrosion product formation process and therefore affect the performance of the corrosion product layer formed under UV illumination.

Anomalous In-Plane Electronic Scattering in Charge Ordered Na0.41CoO20.6H2O  

Science Journals Connector (OSTI)

We report electronic transport measurements on high quality floating zone grown NaxCoO2 and Na0.41CoO20.6H2O single crystals. We find an in-plane electronic scattering minimum near 11K and a clear charge ordering at approximately 50K. The electronic and magnetic properties in hydrated and nonhydrated Na0.41CoO2 samples are similar at higher temperature, but evolve in markedly different ways below ?50??K, where a strong ferromagnetic tendency is observed in the hydrated sample. Model calculations show the relationship of this tendency to the structure of the Fermi surface. The results, particularly the clear differences between the hydrated and nonhydrated material show a substantially enhanced ferromagnetic tendency upon hydration. Implications for superconductivity are discussed.

Electronic, structural, phonon dynamical, and CO{sub 2} capture properties of LiMZrO{sub 3} (M=Na, K) by ab initio thermodynamic investigation  

SciTech Connect

The electronic, structural and phonon properties of LiMZrO{sub 3} (M=Na, K) were investigated by the density functional theory and lattice phonon dynamics. Their thermodynamic properties for CO{sub 2} absorption/desorption were analyzed in comparison with the corresponding M{sub 2}ZrO{sub 3}. Two substituted configurations of LiMZrO{sub 3} were created from Li{sub 2}ZrO{sub 3}. Both types of LiNaZrO3 have direct band gaps with values of 3.84 eV and 3.49 eV respectively. While in the case of LiKZrO{sub 3}, one type has an indirect band gap of 3.79 eV between ? and M high symmetric points while another has a direct band gap of 3.12 eV. The phonon dispersions and phonon density of states of LiMZrO{sub 3} were calculated with the direct method. From the calculated thermodynamic properties of LiMZrO{sub 3} reacting with CO{sub 2}, our results showed that by doping Na into Li{sub 2}ZrO{sub 3}, the obtained new solid LiNaZrO{sub 3} has better performance as a CO{sub 2} sorbent applying to post-combustion capture technology. For K doping into Li{sub 2}ZrO{sub 3}, our calculated thermodynamic results showed that the new solid LiKZrO{sub 3} does not gain improvement on its CO{sub 2} capture performance because its regeneration temperature is much higher than Li{sub 2}ZrO{sub 3}.

Out-of-band exposure characterization with the SEMATECH Berkeley 0.3-NA microfield exposure tool  

SciTech Connect

For the commercialization of extreme ultraviolet lithography (EUVL), discharge or laser produced, pulsed plasma light sources are being considered. These sources are known to emit into a broad range of wavelengths that are collectively referred to as the out-of-band (OOB) radiation by lithographers. Multilayer EUV optics reflect OOB radiation emitted by the EUV sources onto the wafer plane resulting in unwanted background exposure of the resist (flare) and reduced image contrast. The reflectivity of multilayer optics at the target wavelength of 13.5 nm is comparable to that of their reflectivity in the deep ultraviolet (DUV) and UV regions from 100-350 nm. The aromatic molecular backbones of many of the resists used for EUV are equally absorptive at specific DUV wavelengths as well. In order to study the effect of these wavelengths on imaging performance in a real system, we are in the process of integrating a DUV source into the SEMATECH Berkeley 0.3-NA Microfield Exposure Tool (MET). The MET plays an active role in advanced research in resist and mask development for EUVL and as such, we will utilize this system to systematically evaluate the imaging impact of DUV wavelengths in a EUV system. In this paper, we present the optical design for the new DUV component and the simulation-based imaging results predicting the potential impact of OOB based on known resist, mask, and multilayer conditions. It should be noted that because the projection optics work equally well as imaging optics at DUV wavelengths, the OOB radiation cannot be treated simply as uniform background or DC flare.

Photoelectron Spectroscopy and Theoretical Study of M(IO3)2 (M = H, Li, Na, K): Structural Evolution, Optical Isomers and Hyperhalogen Behavior  

SciTech Connect

H(IO3)2- and M(IO3)2- (M = Li, Na, K) anions were successfully produced via electrospray ionization of their corresponding bulk salt solutions, and were characterized by combining negative ion photoelectron spectroscopy and quantum chemical calculations. The photoelectron spectra reveal that all these M(IO3)2- species possess very high vertical detachment energies (VDEs), to be 6.25, 6.57, 6.60 and 6.51 eV for H(IO3)2-, Li(IO3)2-, Na(IO3)2- and K(IO3)2-, respectively, which are much higher than that of IO3- (4.77 eV). The theoretical calculations show that each of these anions has two energetically degenerated optical isomers. It is found that the structure of H(IO3)2- can be written as IO3-(HIO3), in which the H atom is tightly bound to one of the IO3- groups and forms an iodic acid (HIO3) molecule; while the structures of M(IO3)2- can be written as (IO3-)M+(IO3-), in which the alkali metal atoms interact with the two IO3- groups almost equally and bridge the two IO3- groups via two O atoms of each IO3- with the two MOOI planes nearly perpendicular to each other. In addition, the high VDEs of M(IO3)2- (M = Li, Na, K) can be explained by the hyperhalogen behavior of their neutral counterparts.

Isolation and characterization of BetaM protein encoded by ATP1B4 - a unique member of the Na,K-ATPase {beta}-subunit gene family  

SciTech Connect

Highlights: {yields} Structural properties of BetaM and Na,K-ATPase {beta}-subunits are sharply different. {yields} BetaM protein is concentrated in nuclear membrane of skeletal myocytes. {yields} BetaM does not associate with a Na,K-ATPase {alpha}-subunit in skeletal muscle. {yields} Polypeptide chain of the native BetaM is highly sensitive to endogenous proteases. {yields} BetaM in neonatal muscle is a product of alternative splice mRNA variant B. -- Abstract: ATP1B4 genes represent a rare instance of the orthologous gene co-option that radically changed functions of encoded BetaM proteins during vertebrate evolution. In lower vertebrates, this protein is a {beta}-subunit of Na,K-ATPase located in the cell membrane. In placental mammals, BetaM completely lost its ancestral role and through acquisition of two extended Glu-rich clusters into the N-terminal domain gained entirely new properties as a muscle-specific protein of the inner nuclear membrane possessing the ability to regulate gene expression. Strict temporal regulation of BetaM expression, which is the highest in late fetal and early postnatal myocytes, indicates that it plays an essential role in perinatal development. Here we report the first structural characterization of the native eutherian BetaM protein. It should be noted that, in contrast to structurally related Na,K-ATPase {beta}-subunits, the polypeptide chain of BetaM is highly sensitive to endogenous proteases that greatly complicated its isolation. Nevertheless, using a complex of protease inhibitors, a sample of authentic BetaM was isolated from pig neonatal skeletal muscle by a combination of ion-exchange and lectin-affinity chromatography followed by SDS-PAGE. Results of the analysis of the BetaM tryptic digest using MALDI-TOF and ESI-MS/MS mass spectrometry have demonstrated that native BetaM in neonatal skeletal muscle is a product of alternative splice mRNA variant B and comprised of 351 amino acid residues. Isolated BetaM protein was also characterized by SELDI-TOF mass spectrometry before and after deglycosylation. This allowed us to determine that the carbohydrate moiety of BetaM has molecular mass 5.9 kDa and consists of short high-mannose type N-glycans. The results of direct analysis of the purified native eutherian BetaM protein provide first insights into structural properties underlying its entirely new evolutionarily acquired functions.

Influence of ultraviolet light irradiation on corrosion behavior of weathering steel with and without TiO2-coating in 3mass% NaCl solution  

Science Journals Connector (OSTI)

In this study the influence of ultraviolet (UV) light on the corrosion behavior of weathering steel with and without TiO2 coating has been investigated in 3% NaCl solution, using anodic polarization, dipping and dropping tests. In polarization tests a large negative shift of corrosion potential appeared for the TiO2-coated specimen in UV light. The weight loss of the steels with and without TiO2 film increased under UV light in the dipping test, while they decreased in the dropping test. The rust formed on the weathering steel showed a semiconductor like behavior, similar to that shown by TiO2 film.

X-ray Studies of Regenerated Cellulose Fibers Wet Spun from Cotton Linter Pulp in NaOH/Thiourea Aqueous Solutions  

SciTech Connect

Regenerated cellulose fibers were fabricated by dissolution of cotton linter pulp in NaOH (9.5 wt%) and thiourea (4.5 wt%) aqueous solution followed by wet-spinning and multi-roller drawing. The multi-roller drawing process involved three stages: coagulation (I), coagulation (II) and post-treatment (III). The crystalline structure and morphology of regenerated cellulose fiber was investigated by synchrotron wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS) techniques. Results indicated that only the cellulose II crystal structure was found in regenerated cellulose fibers, proving that the cellulose crystals were completely transformed from cellulose I to II structure during spinning from NaOH/thiourea aqueous solution. The crystallinity, orientation and crystal size at each stage were determined from the WAXD analysis. Drawing of cellulose fibers in the coagulation (II) bath (H{sub 2}SO{sub 4}/H{sub 2}O) was found to generate higher orientation and crystallinity than drawing in the post-treatment (III). Although the post-treatment process also increased crystal orientation, it led to a decrease in crystallinity with notable reduction in the anisotropic fraction. Compared with commercial rayon fibers fabricated by the viscose process, the regenerated cellulose fibers exhibited higher crystallinity but lower crystal orientation. SAXS results revealed a clear scattering maximum along the meridian direction in all regenerated cellulose fibers, indicating the formation of lamellar structure during spinning.

High temperature degradation of some steels in V{sub 2}O{sub 5} and Na{sub 2}SO{sub 4} salts  

SciTech Connect

The useful life of superheaters and reheaters of power stations which use heavy oil as fuel are shortened and their continuous service is inhibited by corrosion and creep type problems. The increase of corrosion attack of boilers is caused by the presence of fuel ash deposits containing mainly V, Na and S which form low melting point compounds. In this context, the tubes are exposed to the action of high stresses and high temperatures producing the so called ``creep damage.`` In this work, two kinds of results are reported: laboratory and field studies using stainless steels. The laboratory work was also divided into two parts. In the first one, the steel was exposed under the action of natural ash-deposits in oxidant atmospheres at 600 C for 24 hours. In the second one, tensile specimens were creep-tested in Na{sub 2}SO{sub 4}, V{sub 2}O{sub 5} and a mixture at 580--620 C interval.

Seawater desalination by gas hydrate process and removal characteristics of dissolved ions (Na+, K+, Mg2+, Ca2+, B3+, Cl?, SO42?)  

Science Journals Connector (OSTI)

Abstract In order to evaluate hydrate-based desalination (HBD), experiments with seawater samples were carried out at various conditions (i.e. hydraulic pressure, washing step, and hydrate-forming gas). Before and after the hydrate process, cations (Na+, K+, Mg2+, Ca2+, and B3+) and anions (Cl? and SO42?) were analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and ion chromatography (IC). In a single stage of CO2 hydrate process without any pretreatment, 71%94% of each cation was removed in the following order: K+>Na+?Mg2+?Ca2+>B3+ and 73%83% of each anion was removed. When the brines on the surface of hydrate pellets were removed, the ion removal efficiency increased above 4%. It was also found that the desalting efficiency depended on the hydrate-forming gas (CO2>CH4) and the hydraulic pressure (610MPa) to produce hydrate pellets. In this study, the removal efficiency of cations and anions in a real seawater sample using HBD processes were reported for the first time.

Basic study for the construction of solar cell using CdS photocatalysts and Na{sub 2}S{sub 4} electrolyte  

SciTech Connect

Photoexcited electrons pathway from thin film consisting of semiconductor particles to electrode was tried to develop by using conducting polymers. PEDOT/PSS and polyaniline was selected as transparent conducting polymer material. In the case of the cell consisted by using polyaniline, it was confirmed that conductive emeraldine salt stated polyaniline converted to non-conductive emeraldine base state because of contact with strong basic Na{sub 2}S{sub 4} electrolyte solution. On the other hand, as regards the cell with PEDOT/PSS, it was expected that positive and negative electrode short-circuited and/or Schottky junction was formed between CdS and PEDOT/PSS. The formation of Schottky junction between CdS and PEDOT/PSS was reduced the kinetic energy of the photoexcited electrons to 5.1eV which was the Fermi level of PEDOT. These electrons could not reduce Na{sub 2}S{sub 4} electrolyte solution since oxidation-reduction potential was 4.1eV. As a result, it considered that photoexcited electrons transfer was restricted, which read the decreasement of mobility of photoexcited electron, while the cell without PEDOT/PSS could operate as a solar cell.

Chapter 11 - Systematic Study of the Electronic Properties and Trends in the LiX (X=Na, K, Rb, Cs and Fr) Molecules  

Science Journals Connector (OSTI)

Abstract Alkali mixed diatomic molecules exhibit significant permanent dipole moment. They constitute a prototype of an ultra-cold quantum gas, which makes them candidates for fundamental quantum processes. This requires knowledge of their accurate electronic properties to guide the ongoing experiments. For this purpose, we have investigated the structure and spectroscopic properties of the first electronic states of 1,3?+, 1,3?, 1,3? symmetries for LiNa, LiK, LiRb, and LiCs molecules. We have used an ab initio approach based on pseudopotential techniques: parameterized l-dependent polarization potentials and full configuration interaction calculations through the CIPCI quantum chemistry package. The spectroscopic constants (Re, De, ?e, ?exe, and Be) of these states are derived and compared with the available theoretical and experimental work. In addition to the potential energy, accurate permanent and transition dipole moments are determined for a wide range of internuclear distances. A systematic study and analysis of the trend of the permanent dipole moments around the equilibrium distance of the ground state of LiX (X=Na, K, Rb, Cs and Fr) molecules are done. The results, compared to available theoretical and experimental work, show good agreement.

Structure and properties of Na{sub x}M{sub 2}SbO{sub 6}yH{sub 2}O, M=Co(III), Ni(III) honeycomb oxyhydrates  

SciTech Connect

The oxyhydrates Na{sub 0.85}Co{sub 2}SbO{sub 6}1.7H{sub 2}O and Na{sub 0.95}Ni{sub 2}SbO{sub 6}1.5H{sub 2}O were prepared by Br{sub 2} oxidation of Na{sub 3}Co{sub 2}SbO{sub 6} and Na{sub 3}Ni{sub 2}SbO{sub 6} and exposure to ambient air. Their composition and structure are characterized by thermogravimetric analysis, elemental analysis and powder X-ray diffraction. Both form monolayer hydrates with metal cations (Co or Ni) near the 3+ oxidation state. In the parent materials, MO{sub 6} octahedra surround SbO{sub 6} units, forming a honeycomb geometry; Rietveld refinement of the hydrate phases indicate that this motif is retained. Magnetic susceptibility plots display paramagnetic behavior and CurieWeiss fits support the 3+ oxidation state (low spin d{sup 6}s=0 for Co and low spin d{sup 7}s=1/2 for Ni). Close inspection of the Ni hydrates susceptibility reveals a feature at 6.2 K and a non-linear magnetization at 2 K with no saturation up to 9 T. Heat capacity measurements show a large amount of excess entropy in the Ni hydrate in the 220 K temperature range, while the heat capacity of the Co hydrate can be described by a simple lattice contribution. The Ni hydrate sample is easily dehydrated by heating above 100 C and forms a new Na-deficient phase, Na{sub 0.95}Ni{sub 2}SbO{sub 6}, which is stable at room temperature. Magnetic susceptibility of this phase is consistent with the Ni atom remaining in the 3+ oxidation state after dehydration. - Graphical abstract: Powder diffraction patterns of Na{sub 3}Ni{sub 2}SbO{sub 6}, Na{sub 0.95}Ni{sub 2}SbO{sub 6}1.5H{sub 2}O and Na{sub 0.95}Ni{sub 2}SbO{sub 6}. Each pattern has been normalized in intensity. Cartoons depict the change in layer separation with hydration and give the approximate distances between layers and Ni atoms. Highlights: New oxyhydrate phases with honeycomb lattices are formed. CurieWeiss fits indicate Ni{sup 3+} (s=1/2). Heat capacity shows a large release of entropy for Ni phase, likely due to a complex magneto-structural phase transition.

Thermodynamic modeling of neptunium(V) solubility in concentrated Na-CO{sub 3}-HCO{sub 3}-Cl-ClO{sub 4}-H-OH-H{sub 2}O systems  

SciTech Connect

Safety assessments of nuclear waste repositories often require estimation of actinide solubilities as a function of groundwater composition. Although considerable amount of research has been done on the solubility and speciation of actinides, relatively little has been done to unify these data into a model applicable to concentrate brines. Numerous authors report data on the aqueous chemical properties of Np(V) in NaClO{sub 4}, Na{sub 2}CO{sub 3}, and NaCl media, but a consistent thermodynamic model for predicting these properties is not available. To meet this need, a model was developed to describe the solubility of Np(V) in Na-Cl-ClO{sub 4}-CO{sub 3} aqueous systems, based on the Pitzer activity coefficient formalism for concentrated electrolytes. Hydrolysis and/or carbonate complexation are the dominant aqueous reactions with neptunyl in these systems. Literature data for neptunyl extraction and solubility, and solubility data that the authors developed, are used to parameterize an integrated model for Np(V) solubility in the Np(V)-Na-CO{sub 3}-HCO{sub 3}-Cl-ClO{sub 4}-H-OH-H{sub 2}O system. The resulting model is tested against additional solubility data, and compared with Np(V) solubility experiments in complex synthetic brines.

Synthetic fluid inclusions: VIII. Vapor-saturated halite solubility in part of the system NaCl-CaCl sub 2 -H sub 2 O, with application to fluid inclusions from oceanic hydrothermal systems  

SciTech Connect

Halite solubility along part of the vapor-saturated liquidus in the system NaCl-CaCl{sub 2}-H{sub 2}O has been determined using the synthetic fluid inclusion technique. Data allow the construction of liquidus isotherms for temperatures up to 500{degree}C and bulk compositions containing >60 wt% total salt and as much as 25 wt% CaCl{sub 2}. Combined with previous data for the binary system NaCl-H{sub 2}O and for the ternary system NaCl-CaCl{sub 2}-H{sub 2}O in the low-salinity, low-temperature region, a preliminary ternary phase diagram can be constructed that remains incomplete only in the CaCl{sub 2}-rich region. Results are applied to the interpretation of saline fluid inclusions from quartz veins in oceanic metagabbros, and can be applied to many other natural inclusions containing aqueous solutions with NaCl and CaCl{sub 2} the dominant solutes. Microthermometric measurements at equilibrium of the melting temperature of ice (Tm (ice)) and of the dissolution temperature of halite (Tm (halite)) are sufficient to determine the bulk composition of the NaCl-CaCl{sub 2}-H{sub 2}O fluid.

Effect of Quantitative Trait Loci for Milk Protein Percentage on Milk Protein Yield and Milk Yield in Israeli Holstein Dairy Cattle  

Science Journals Connector (OSTI)

Although numerous quantitative trait loci (QTL) mapping studies involving milk protein percent (PP), milk yield (MY), and protein yield (PY) have been carried out, there has not been any systematic evaluation of the effects of individual QTL on these 3 interrelated traits. Consequently, the aim of the present study was to investigate the effects on MY and PY of QTL for PP previously mapped in various laboratories. The study, based on selective DNA pooling of milk samples, included 10 Israeli Holstein artificial insemination bulls, each the sire of 1,800 or more milk-recorded daughters. For each sire-trait combination across the 10 sires, milk samples of the highest and lowest daughters with respect to estimated breeding values for PP, PY, and MY were collected for pooling. A total of 134 dinucleotide microsatellites distributed over 25 bovine autosomes were used. An empirical standard error for marker-QTL linkage testing was calculated based on the variation among split samples within the same tail. Threshold comparison-wise error rate P-values were set to control proportion of false positives at P=0.10 level for declaring significant effects at the marker-trait level. Estimates of the number of true null hypotheses for each trait were obtained from the histogram of marker comparison-wise error rate P-values. Based on these estimates, effective power of the experiment at the marker-trait level was estimated as 0.75, 0.41, and 0.73 for PP, PY, and MY. The proportion of heterozygosity at the QTL was estimated as 0.46, 0.39, and 0.40, respectively. After correcting for incomplete power and proportion of false positives, it was estimated that 38.7 and 37.5% of the markers affecting PP and MY, respectively, also affected PY. Of the markers affecting PY, 68.9 and 76.5%, respectively, also affected PP and MY. Apparently, none of the significant markers affected PY exclusively, and only 6.5 and 16.0%, respectively, affected PP or MY exclusively. Thus, almost all significant markers, and by inference almost all QTL, had effects on at least 2 of the 3 traits.

Fe isotope fractionation during phase separation in the NaClH2O system: An experimental study with implications for seafloor hydrothermal vents  

Science Journals Connector (OSTI)

Abstract Phase separation has been proposed as a possible mechanism contributing to the Fe isotope composition of hydrothermal fluids at mid-ocean ridges. The uncertainty results largely from the emphasis on field data that can involve competing processes that obscure cause and effect of any one process. To better understand the potential significance of phase separation in the NaClFeH2O system on Fe isotope fractionation, temperature and pressure of a Fe-bearing NaCl fluid in a titanium flow reactor were carefully adjusted to produce vapor liquid halite, while the Fe isotope composition between coexisting phases was monitored. Two different PT regions were emphasized: (1) 424420?C, 35.231.5 MPa; and (2) 464466?C, 29.824.7 MPa. Both regions were chosen to simulate the range of physical conditions that are experienced by hydrothermal fluids at mid-ocean ridges (MORs). Decompression induced phase separation in both PT regions results in the vapor phase becoming enriched in the heavier isotopes of Fe, as the Fe/Cl ratio decreases. The coexisting NaCl-rich liquid phase remains essentially constant with respect to Fe/Cl ratio and Fe isotope composition. Coinciding with the lowest vapor chlorinity in the vaporliquid stability field, the Fe/Cl ratio of the vapor abruptly increases, while the Fe isotope fractionation between the vapor and liquid ( 10 3 ln ? ? V / L 56 / 54 ) reached a maximum value of + 0.145 0.048 . Subsequently, Fe isotope fractionation decreased upon transition into the vaporhalite stability field (PT region 2). We infer that the observed Fe isotope fractionation between vapor liquid halite is caused by differences in Fe speciation among coexisting chloride-bearing phases. The experimental study confirms for the first time that measurable Fe isotope variability can result from phase separation in high temperature hydrothermal systems. The species-dependent Fe isotope fractionation reported here is small relative to predicted mineralmineral and mineralfluid fractionations, especially if redox effects are involved as might occur during vent fluidseawater mixing reactions and/or magmatic activity associated with seafloor eruptive episodes.

With the content of Na ion increasing, the changes of lattice parameters, energy gaps, bond lengths and optical properties of K{sub 1-x}Na{sub x}TaO{sub 3} are regular. Moreover, the dependence of ferroelectric photocatalysis on both optical properties and internal electronic structure are analyzed in detail.

Correlation between Charge State of Insulating NaCl Surfaces and Ionic Mobility Induced by Water Adsorption: A Combined Ambient Pressure X-ray Photoelectron Spectroscopy and Scanning Force Microscopy Study  

SciTech Connect

In situ ambient pressure X-ray photoelectron spectroscopy (APPES) and scanning force microscopy were used to characterize the surface discharge induced by water layers grown on (001) surfaces of sodium chloride single crystals. The APPES studies show that both kinetic energy (KE) and full width at half-maximum (FWHM) of the Na 2s and Cl 2p core level peaks, monitored as a function of relative humidity (RH), mimic surface conductivity curves measured using scanning force microscopy. The KE position and FWHM of the core level peaks therefore are directly related to the solvation and diffusion of ions at the NaCl(100) surface upon adsorption of water.

An accurate PVT model for geothermal fluids as represented by H{sub 2}O-CO{sub 2}-NaCl mixtures  

SciTech Connect

Estimates for the pressure decline in high TDS geothermal fluids containing dissolved gases are extremely sensitive to the PVT representation of the reservoir fluid. Significant errors in predicted pressures will occur if the geothermal fluid is represented by one or two pseudo components with modified water properties. As a result, we have developed a PVT model to predict the thermodynamic properties of a prototype geothermal fluid as represented by three-component H{sub 2}O-CO{sub 2}-NaCl mixtures. The range of applicability of the model is: Temperatures from 75 to 700+ F, pressures from 14.7 to 5000 psi, carbon dioxide content from 0-5 wt%, and salt concentrations to 30 wt%. The model has been implemented into Unocal's version of a commercially available reservoir simulator and is currently being used to study one of Unocal's high salinity reservoirs located in the Imperial Valley of California.

Jupiter as an exoplanet: UV to NIR transmission spectrum reveals hazes, a Na layer and possibly stratospheric H2O-ice clouds  

E-Print Network (OSTI)

Currently, the analysis of transmission spectra is the most successful technique to probe the chemical composition of exoplanet atmospheres. But the accuracy of these measurements is constrained by observational limitations and the diversity of possible atmospheric compositions. Here we show the UV-VIS-IR transmission spectrum of Jupiter, as if it were a transiting exoplanet, obtained by observing one of its satellites, Ganymede, while passing through Jupiter's shadow i.e., during a solar eclipse from Ganymede. The spectrum shows strong extinction due to the presence of clouds (aerosols) and haze in the atmosphere, and strong absorption features from CH4. More interestingly, the comparison with radiative transfer models reveals a spectral signature, which we attribute here to a Jupiter stratospheric layer of crystalline H2O ice. The atomic transitions of Na are also present. These results are relevant for the modeling and interpretation of giant transiting exoplanets. They also open a new technique to explore...

Science Journals Connector (OSTI)

X-ray and Raman measurements show that crystalline Ca(NO3)2/NaNO3 becomes amorphous above a pressure of 9.4 GPa. Upon release of the pressure, the crystalline state returns. We report reversible pressure-induced amorphization for a substance that can be prepared as a melt-quenched glass at ambient pressure. We suggest a mechanism for the amorphization based on the formation of a noncrystallographic packing of polytetrahedral units. A consideration of several pressure-induced amorphizations indicates that polytetrahedral amorphization mechanisms are appropriate for nondirectionally bonded materials, but are not appropriate for solids where covalent and hydrogen bonding predominates. Polytetrahedral ordering provides a link between amorphous states formed by compression and those formed by more conventional methods at ambient pressure (e.g., melt quenching).

A KEY PHYSICAL MECHANISM FOR UNDERSTANDING THE ENIGMATIC LINEAR POLARIZATION OF THE SOLAR Ba II AND Na I D{sub 1} LINES  

SciTech Connect

The linearly polarized spectrum of the solar limb radiation produced by scattering processes is of great diagnostic potential for exploring the magnetism of the solar atmosphere. This spectrum shows an impressive richness of spectral details and enigmatic Q/I signals, whose physical origin must be clearly understood before they can be exploited for diagnostic purposes. The most enduring enigma is represented by the polarization signals observed in the D{sub 1} resonance lines of Na I (5896 A) and Ba II (4934 A), which were expected to be intrinsically unpolarizable. The totality of sodium and 18% of barium have hyperfine structure (HFS), and it has been argued that the only way to produce a scattering polarization signal in such lines is through the presence of a substantial amount of atomic polarization in their lower HFS levels. The strong sensitivity of these long-lived levels to depolarizing mechanisms led to the paradoxical conclusion that the observed D{sub 1}-line polarization is incompatible with the presence in the lower solar chromosphere of inclined magnetic fields sensibly stronger than 0.01 G. Here we show that by properly taking into account the fact that the solar D{sub 1}-line radiation has a non-negligible spectral structure over the short frequency interval spanned by the HFS transitions, it is possible to produce scattering polarization signals in the D{sub 1} lines of Na I and Ba II without the need of ground-level polarization. The resulting linear polarization is not so easily destroyed by elastic collisions and/or magnetic fields.

Phase relations in the system NaCl-KCl-H/sub 2/O. III. Solubilities of halite in vapor-saturated liquids above 445/sup 0/C and redetermination of phase equilibrium properties in the system NaCl-H/sub 2/O to 1000/sup 0/C and 1500 bars  

SciTech Connect

Halite solubilities along the three-phase curve in the binary system NaCl-H/sub 2/O determined by differential thermal analysis (DTA) experiment can be represented by the discussed equation where 447 less than or equal to T less than or equal to 800/sup 0/C. Even though these halite solubilities are up to approx. 7 wt.% higher than those reported in literature, extrapolated values at temperatures below 447/sup 0/C merge with the literature values. It is considered that the equation adequately describes halite solubilities between 382 and 800/sup 0/C. The newly established solubility data are believed to be more reliable because they are compatible with data obtained by using synthetic fluid inclusions and with the observed DTA signals and also because they were measured in a relatively corrosion-free system. In an earlier publication the authors were puzzled greatly by multiple and rather unreproducible DTA peaks appearing during isobaric cooling at pressures below about 500 bars. These DTA signals apparently suggested that the halite liquidus swung sharply upward in temperature as pressure decreased from about 500 bars to that of the halite-saturated boiling curve. Further analysis of the data and helpful discussions with several individuals have revealed that the behavior is a consequence of the initial separation of the fluid into NaCl-poor gas and NaCl-rich liquid that failed to homogenize in the short time encompassed by the DTA experiments. The present analysis is based on extrapolations of the dP/dT slopes from pressures above 500 bars.

Synthetic fluid inclusions: XIII. Experimental determination of PVT properties in the system H{sub 2}O + 40 wt% NaCl + 5 mol% CO{sub 2} at elevated temperature and pressure  

SciTech Connect

The location of the liquid + vapor {yields} liquid phase boundary and the P-T slopes of iso-Th lines were determined for a constant composition of 40 {+-} 0.1 wt% NaCl 5 {+-} 0.15 mol% CO{sub 2} (both relative) to H{sub 2}O at high density. Synthetic fluid inclusions with this composition were formed in cold-seal pressure vessels at pressures of 2 and 4 kbar and temperatures between 350{degrees}C and 700{degrees}C. The inclusions were analyzed on a gas-flow heating/cooling stage to determine the temperatures of halite dissolution [Tm{sub (H+L+V{yields}L+V)}] and total homogenization [Th{sub (L+V{yields}L)}]. Addition to 40 wt% NaCl to an aqueous solution containing 5 mol% CO{sub 2} causes a significant shift of the liquid + vapor {yields} liquid boundary towards higher pressures. The slopes of the iso-Th lines decrease from 29.5 bars/{degrees}C for Th{sub (L+V{yields}L)} of 400{degrees}C, to 6.4 bars/{degrees}C for Th{sub (L+V{yields})} = 600{degrees}C. Addition of 5 mol% CO{sub 2} to an aqueous solution containing 40 wt% NaCl results in halite dissolution temperatures that are slightly higher (Tm{sub (H+L+V{yields}L+V)} {approx} 332{degrees}C) than the literature value of 323{degrees}C for the vapor-saturated liquidus of an H{sub 2}O-40 wt% NaCl mixture. Calculated molar volumes for 40 wt% NaCl + 5 mol% CO{sub 2} solutions at 2 and 4 kbar show trends that are similar to those of other compositions in the ternary system H{sub 2}O-CO{sub 2}-NaCl at the same pressures and temperatures. In the P-T range of this study, all excess volumes are negative and lie between the values for the compositions H{sub 2}O-5 mol% CO{sub 2} and H{sub 2}O-40 wt% NaCl. 30 refs., 6 figs., 2 tabs.

Activation of K{sup +} channels and Na{sup +}/K{sup +} ATPase prevents aortic endothelial dysfunction in 7-day lead-treated rats  

SciTech Connect

Seven day exposure to a low concentration of lead acetate increases nitric oxide bioavailability suggesting a putative role of K{sup +} channels affecting vascular reactivity. This could be an adaptive mechanism at the initial stages of toxicity from lead exposure due to oxidative stress. We evaluated whether lead alters the participation of K{sup +} channels and Na{sup +}/K{sup +}-ATPase (NKA) on vascular function. Wistar rats were treated with lead (1st dose 4 ?g/100 g, subsequent doses 0.05 ?g/100 g, im, 7 days) or vehicle. Lead treatment reduced the contractile response of aortic rings to phenylephrine (PHE) without changing the vasodilator response to acetylcholine (ACh) or sodium nitroprusside (SNP). Furthermore, this treatment increased basal O{sub 2}{sup ?} production, and apocynin (0.3 ?M), superoxide dismutase (150 U/mL) and catalase (1000 U/mL) reduced the response to PHE only in the treated group. Lead also increased aortic functional NKA activity evaluated by K{sup +}-induced relaxation curves. Ouabain (100 ?M) plus L-NAME (100 ?M), aminoguanidine (50 ?M) or tetraethylammonium (TEA, 2 mM) reduced the K{sup +}-induced relaxation only in lead-treated rats. When aortic rings were precontracted with KCl (60 mM/L) or preincubated with TEA (2 mM), 4-aminopyridine (4-AP, 5 mM), iberiotoxin (IbTX, 30 nM), apamin (0.5 ?M) or charybdotoxin (0.1 ?M), the ACh-induced relaxation was more reduced in the lead-treated rats. Additionally, 4-AP and IbTX reduced the relaxation elicited by SNP more in the lead-treated rats. Results suggest that lead treatment promoted NKA and K{sup +} channels activation and these effects might contribute to the preservation of aortic endothelial function against oxidative stress. -- Highlights: ? Increased free radicals production ? Increased Na{sup +}/K{sup +} ATPase activity ? Promotes activation of the K{sup +} channels and reduced vascular reactivity ? These effects preserve endothelial function against oxidative stress. ? Low concentrations constitute environmental cardiovascular risk factor.

Laser cooling of the vibrational motion of Na{sub 2} combining the effects of zero-width resonances and exceptional points  

SciTech Connect

We propose various scenarios for molecular vibrational cooling combining the effects of two kinds of resonance states occurring during the photodissociation of Na{sub 2} taken as an illustrative example. Such resonances result from an appropriate sampling of laser parameters (wavelength and intensity): (a) For particular choices of intensity and wavelength, two resonance energies can be brought to complete coalescence, with their positions and widths becoming equal and leading to a so-called exceptional point (EP) in the parameter plane. Advantage can be taken from such points for very selective laser-controlled vibrational transfer strategies. (b) For specific intensities, far beyond the perturbation regime, some resonances can have a zero width (infinite lifetime). They are referred to as a zero-width resonance (ZWR) and may be used for vibrational purification purposes. We show how appropriately shaped, experimentally reachable laser pulses, encircling EPs or inducing ZWRs, may be used for a thorough and comprehensive control aiming at population transfer or purification schemes, which, starting from an initial field-free vibrational distribution, ends up in the ground vibrational level.

Band structures and charge densities of KCl, NaF, and LiF obtained by the intersecting-spheres model  

Science Journals Connector (OSTI)

The self-consistent electronic structures of KCl, NaF, and LiF have been calculated by the intersecting-spheres model and the results were compared with band structures calculated by other methods using the approximation of the exchange potential adopted by us. While for KCl close agreement was found between the augmented-plane-wave non-muffin-tin results by De Cicco and the intersecting-spheres-model (ISM) band structure, in the case of LiF differences of even 2.5 eV were found between conduction bands calculated by the ISM and the corresponding levels determined by linear-combination-of-atomic-orbitals (LCAO) methods. This disagreement seems to be imputable to a lack of convergence occurring in the LCAO calculations. The Fourier components of the charge densities (scattering factors) were determined using the Kohn-Sham-Gspr form of the exchange potential. The agreement of the calculated scattering factors with experiment is not much worse than that obtained by Hartree-Fock calculations.

Etching properties of Na0.5K0.5NbO3 thin films by using inductively coupled CF4/Ar plasma  

Science Journals Connector (OSTI)

Abstract The etch process of the Na0.5K0.5NbO3 (NKN) thin film was performed in CF4/Ar plasma. We investigated the etch rate of the NKN thin films and the selectivity of NKN to SiO2 in an inductively coupled plasma. The maximum etch rate of the NKN thin films was 127.3nm/min in CF4/Ar (=4:16sccm) plasma and the selectivity of NKN to SiO2 was 0.31. We analyzed the XPS narrow scan spectra for the reaction on the surface of the NKN thin films. From the XPS data analysis, we were assumed that the byproducts were generated on the surface of the NKN thin films during the etching process, but the physical sputtering process effectively removed the byproducts. We analyzed the morphologies of the surface of the NKN thin films from AFM measurement. The Ar concentration affects the surface morphology greatly.

NHE10, a novel osteoclast-specific member of the Na{sup +}/H{sup +} exchanger family, regulates osteoclast differentiation and survival  

SciTech Connect

Bone homeostasis is tightly regulated by the balanced actions of osteoblasts (OBs) and osteoclasts (OCs). We previously analyzed the gene expression profile of OC differentiation using a cDNA microarray, and identified a novel osteoclastogenic gene candidate, clone OCL-1-E7 [J. Rho, C.R. Altmann, N.D. Socci, L. Merkov, N. Kim, H. So, O. Lee, M. Takami, A.H. Brivanlou, Y. Choi, Gene expression profiling of osteoclast differentiation by combined suppression subtractive hybridization (SSH) and cDNA microarray analysis, DNA Cell Biol. 21 (2002) 541-549]. In this study, we have isolated full-length cDNAs corresponding to this clone from mice and humans to determine the functional roles of this gene in osteoclastogenesis. The full-length cDNA of OCL-1-E7 encodes 12 membrane-spanning domains that are typical of isoforms of the Na{sup +}/H{sup +} exchangers (NHEs), indicating that this clone is a novel member of the NHE family (hereafter referred to as NHE10). Here, we show that NHE10 is highly expressed in OCs in response to receptor activator of nuclear factor-{kappa}B ligand signaling and is required for OC differentiation and survival.
