51. Simulation study of the ferrous ferric electron transfer at a metal–aqueous electrolyte interface

Author: B. B. Smith and J. W. Halley
Subjects: Work (thermodynamics), Reaction mechanism, Electron transfer, Chemistry, Chemical physics, Inorganic chemistry, General Physics and Astronomy, Rectangular potential barrier, Work function, Electrolyte, Physical and Theoretical Chemistry, Electrochemistry, Redox
Abstract: We report a new simulation study of the rate of ferrous–ferric electron transfer at a metal electrolyte interface. In contrast with earlier work, new features in our study include a detailed account of the effects of the field associated with the charging of the electrode, inclusion of entropic effects in the calculated free energy barriers, and a study of the dependence of the relevant free energy surfaces on the distance of the ion from the electrode. The qualitative picture of the reaction mechanism which emerges is significantly more detailed than that in earlier work. The dominant factors in determining the rate and mechanisms of electron transfer are the distance dependence of the work function of the metal, the redox species concentration profile, and the electronic matrix element. Calculated free energy barriers are consistent with experimentally measured ones. We also estimate the equilibrium potential for this reaction from the model, and find it to be consistent with the experimental equilibrium potential.

52. Geochemistry, the new geophysics? Minerals keynote paper

Author: Scott W. Halley
Subjects: geography, geography.geographical_feature_category, Pathfinder, General Engineering, Extrapolation, Geochemistry, Earth materials, Rock types, Geophysics, Sedimentary basin, Geology, Analysis method, Interpolation
Abstract: Both geochemical and geophysical responses of earth materials are governed by mineralogy. It should therefore come as no surprise that geochemical and geophysical patterns are strongly correlated. Using a strong acid digest and a combined ICP MS/AES analytical package, we can now analyse half of the periodic table with very low detection limits, for around the same real dollar cost that Au plus base metals would have cost 30 years ago. With the new analysis methods, we can classify rock types, quantify the intensity of alteration, as well as map pathfinder metals. Integrating chemistry with geophysical data adds a new level of understanding to the meaning of the geophysical patterns. An example from Zambia shows a district-scale alteration map. Correlation with airborne radiometrics and magnetics allows interpolation between sample points, and extrapolation across a whole province. The hydrology of an entire sedimentary basin can be mapped from the combination of data.

56. New approach to the observation of the condensate fraction in superfluid helium-4

Abstract: We present a phenomenological analysis of an experiment to observe the condensate fraction of helium-4 by firing low-energy pulses of helium atoms at suspended droplets of the superfluid and observing the resulting emission of helium atoms from the fluid. Emission occurs through a conventional process in which rotons are produced and propagate to the other side of the droplet, and through a second process depending on the existence of the condensate. If A is the area of the incoming beam, the cross section scales with A 2 (first process) and A 4 (second process), respectively, for small A. Aspects of a full many body calculation and the performance of such an experiment are briefly discussed

57. Calculation of the inelastic-light-scattering spectrum inHe4in the two-body approximation

Author: A. J. Wissink, J W Halley, and M. S. Korth
Subjects: Many-body problem, Physics, Scattering, Quantum mechanics, Quasiparticle, Inelastic scattering, Two-body problem, Roton, Light scattering, Spectral line
Abstract: We describe calculations of the inelastic-light-scattering spectrum for frequencies of the order of up to several times the roton frequency. The calculations are based on the two-body approximation in a theoretical description of the fluid due to Manousakis and Pandharipande. On the basis of earlier results we calculate only the contribution arising from quasiparticle anharmonicities in the spectrum and take full account of the strong dependence of the three-quasiparticle coupling on the magnitudes and directions of the momenta of the quasiparticles, which is implied by the two-body approximation. The results are compared with recent experimental results. At high energies, the calculated spectrum is in most respects consistent with the experimental one. We discuss the possible origins of the remaining discrepancies.

58. Possibility of two types of localized states in a two-dimensional disordered lattice

Author: Herbert B. Shore, Nacir Tit, J. W. Halley, and Narendra Kumar
Subjects: chemistry.chemical_classification, Physics, Condensed matter physics, Equations of motion, Square lattice, symbols.namesake, Tight binding, chemistry, Electrical resistivity and conductivity, Lattice (order), Density of states, symbols, Hamiltonian (quantum mechanics), Inorganic compound
Abstract: We report results of our numerical calculations, based on the equation of motion method, of dc electrical conductivity, and of density of states for up to 40×40 two-dimensional square lattices modeling a tight-binding Hamiltonian for a binary (AB) compound, disordered by randomly distributed B vacancies up to 10%. Our results indicate strongly localized states away from band centers separated from the relatively weakly localized states towards midband. This is in qualitative agreement with the idea of a "mobility edge" separating exponentially localized states from the power-law localized states as suggested by the two-parameter scaling theory of Kaveh in two dimensions. An alternative explanation, consistent with one-parameter scaling theory, is that the observed numerical effects may arise as a consequence of the variation of the localization length over the band.

59. Water penetration in glassy polymers: Experiment and theory

Subjects: Condensed Matter::Quantum Gases, chemistry.chemical_classification, Molecular diffusion, Polymers and Plastics, Infrared, General Chemistry, Trapping, Penetration (firestop), Polymer, Surfaces, Coatings and Films, Condensed Matter::Soft Condensed Matter, chemistry, Chemical physics, Polymer chemistry, Materials Chemistry, Nonlinear diffusion
Abstract: We describe the design and implementation of a method based on infrared monitoring of the OD stretch mode which permits measurement of the diffusion profiles of water permeating glassy polymers for the first time. Results for several glassy polymers are compared with a theory of trapping diffusion which leads to a nonlinear diffusion problem in which the trapped water penetrates the polymer as a sharp front if there is a large amount of trapping. In the case of two of the polymers studied, the trapping model describes the data, very well (much better than a simple diffusion model) and permits determination of parameters related to the free volume and the residence time of the water on traps in the model. © 1993 John Wiley & Sons, Inc.

60. A polarizable, dissociating molecular dynamics model for liquid water

Author: James R. Rustad, A. Rahman, and J. W. Halley
Subjects: Dipole, Molecular dynamics, Polarizability, Computational chemistry, Chemistry, Monte Carlo method, Water model, General Physics and Astronomy, Statistical physics, Physical and Theoretical Chemistry, Parameter space, Three-body problem, Local field
Abstract: We describe a molecular dynamics model for dissociable, polarizable water. The model, which describes both the static and dynamic properties of real water quite reasonably, contains the following features: Self‐consistent local fields are calculated in an extension of an earlier algorithm in which the dipole moments of the water are treated as dynamical variables. An intramolecular three‐body potential assures that the molecular properties of water are in agreement with experiment. Ewald methods are used to take account of monopole–dipole and dipole–dipole as well as monopole–monopole interactions. The model was optimized using a Monte Carlo procedure in the parameter space which is described.

61. Role of oxygen vacancies in anodic TiO2 thin films

Abstract: Defects play an important role in the electronic and optical properties of amorphous solids in general. Here we present both experimental and theoretical investigations on the nature and origin of defect states in anodic rutile TiO 2 thin films (thickness 5–20 nm). There is experimental evidence that the observed gap state at 0.7 eV below the edge of the conduction band is due to an oxygen vacancy. For this reason oxygen vacancies are used in our model. A comparison of the calculated bulk-photoconductivity to photospectroscopy experiment reveals that the films have bulk-like transport properties. On the other hand, a fit of the surface density of states to the scanning tunneling microscopy (STM) on the (001) surfaces has suggested a surface defect density of 5% of oxygen vacancies. To resolve this discrepancy, we calculated the DC-conductivity where localization effects are included. Our results show an impurity band formation at about p c =9% of oxygen vacancies. We concluded that the gap states seen in STM are localized and the oxygen vacancies are playing the role of trapping centers (deep levels) in the studied films.

Abstract: We present a theoretical investigation to explain the electronic and optical properties of anodic rutile TiO2 thin films of different thicknesses (ranging from 5nm to 20nm). There is experimental evidence that the observed gap state at 0.7eV below the edge of conduction-band is due to an oxygen vacancy. For this reason, oxygen vacancies are used as defects in our model. A comparison of the calculated bulk-photoconductivity to photospectroscopy experiment reveals that the films have bulk-like transport properties with a bandgap Eg = 3.0eV. On the other hand, a fit of the surface density of states to the scanning tunneling microscopy (STM) experiment on the (001) surfaces has suggested a surface defect density of 5% of oxygen vacancies. To resolve this discrepancy, we calculated the dc-conductivity where localization effects are included. Our results show an impurity band formation at about pc = 9% of oxygen vacancies. We concluded that the studied films have defect densities below the threshold of impurity band formation. As a consequence the gap states seen in STM are localized (i.e: the oxygen vacancies are playing the role of trapping centers, deep levels) and the mobility edge is invariant.

Abstract: We describe mean-field calculations of the properties of the dilute {ital t}-{ital J} model for high-{ital T}{sub {ital c}} superconductors. We first discuss a physical motivation for the model in terms of the effects of oxygen vacancies and the appropriate parametrization for a qualitative description of high-{ital T}{sub {ital c}} superconductors. We briefly review our mean-field numerical methods. We present results on the density of states, local carrier density, the transition temperature as a function of carrier concentration, oxygen-vacancy concentration, and elastic-scattering impurity concentration, as well as the dc conductivity. These are compared with experiment on high-{ital T}{sub {ital c}} materials. We conclude that the model is a promising framework for understanding high-{ital T}{sub {ital c}} materials microscopically.

64. Electronic properties of disordered anodic TiO2 (001) surfaces: Application of the equation-of-motion method

Abstract: We report calculations of the electronic properties for rutile TiO2 (001) surfaces using the equation-of-motion (EOM) method. We use a full tight-binding Hamiltonian developed by Vos to describe the electronic structure. In contrast to the Green's-function (GF) method which is traditionally used for such a problem, the EOM method gives excellent results with large systems and any number of defects, and puts no restriction on the range of the impurity potential. There is experimental evidence that the observed gap state at 0.7 eV below the conduction-band edge is due to an oxygen vacancy. For this reason we study the electronic properties of disordered surfaces as a function of oxygen vacancy concentrations (up to 10%). Our results are applied to the interpretation of recent scanning tunneling Microscopy (STM) experiments on anodic rutile TiO2 (001) films (whose thickness is ∼ 150 A), and the density of surface defects is estimated. Special care was paid to the study of the nature of gap states. Our results show that these states are localized and play the role of trapping centers which impede the conduction in the films and that no impurity band exists for the studied surfaces. We use both conductivity and local density of states (LDOS) calculations to draw this conclusion. In agreement with experiments, no contribution from gap states in the transport was confirmed in our work. We also report the LDOS calculations on a few sites around the defect at the surface. This in turn gives information about both the spatial decay of the bound-state wave function (localization) and the existence of the impurity band.

65. Final Report for Department of Energy grant DE-FG02-91ER45455, 'Theoretical Study of Reactions at the Electrode-Electrolyte Interface'

Author: J. W. Halley
Subjects: Anatase, Materials science, Inorganic chemistry, Oxide, chemistry.chemical_element, Context (language use), Titanium oxide, chemistry.chemical_compound, Tight binding, chemistry, Chemical physics, Rutile, Crystallite, Titanium
Abstract: In this project, reaction rates were predicted by numerical methods, in a collaboration with Argonne National Laboratory . Emphasis is on electron transfer and transport involving ions known to be important in enhancing stress corrosion cracking in light water reactors and on electron transfer at oxide surfaces. In the latter part of the grant period we placed increased emphasis on development and use of self consistent tight binding methods for this kind of study. We showed that by careful fitting of results from first principles plane wave calculations,we could model surfaces and interfaces oxides and metals using these methods. We obtained results for the titanium/titanium oxide interface in this way and completed a model of the ruthenium dioxide surface using our innovative self consistent tight binding molecular dynamics methods. We completed development of a description of liquid water within the self consistent tight binding context and studied the rutile water 110 interface to determine if it is hydroxylated. A self consistent tight binding study of titanium metal surfaces demonstrated the usefulness of this method for metals. In collaboration with the Argonne group, we extended the tight binding calculations on rutile titania to the anatase form and made the first calculations of the relative stability of anatase and rutile as a function of crystallite size. We completed studies of small anatase particles in water using the method and found significant distortions of nanoparticle crystallite shapes as a consequence of interactions with the water.

Abstract: We describe experimental and theoretical studies of titanium dioxide. Photoelectrochemical data are presented for surfaces of known structure. The oxides were grown anodically on titanium metal. We report calculations of the electronic densities of states and optical conductivities of rutile TiO 2 in finite-size samples disordered by the addition of oxygen vacancies for comparison with experiments. We conclude that in less disordered surfaces the electronic structure exhibited by the photospectra is very close to that of bulk rutile TiO 2 . In contrast, very thin oxides showed evidence of an electronic structure dominated by localized states near the band edge. More disordered oxides gave photospectra in which transitions associated with direct band gap transitions in bulk TiO 2 seem to have been suppressed. Taking the structural information on the oxides into account, we argue that this suppression is probably a matrix element effect.

Finally we discuss possible microscopic mechanisms by which point defects could enhance pairing in the BCS state.

68. Temperature Dependence of the Heterogeneous Ferrous‐Ferric Electron Transfer Reaction Rate: Comparison of Experiment and Theory

Abstract: This paper describes experiments on the temperature dependence of the rate of the ferrous-ferric electron transfer reaction at a gold electrode and compare them with a detailed molecular dynamics simulation which is used to predict the rate. We find from the experiments that the temperature dependence of the rate has the Arrhenius form over the temperature range from 25 to 275{degrees} C, and that the transfer coefficient is independent of temperature in this range. The molecular dynamics simulations are used to two ways to extract activation energies and transfer coefficients for comparison with experiment. In one of these methods, we assume parabolic dependence of the energies for the product and reactant in a reaction coordinate which is not specified a priori. In the other method, we use a quantum mechanical calculation extrapolated from the very short molecular dynamics time scale to times characteristic of the electron transfer rate. The assumption of parabolic dependence of the energies gives an estimate for the activation energy which is consistent with experiment. The transfer coefficient calculated using this assumption is also consistent with experiment.

69. The Graduate Record Examination as an indicator of learning of the curriculum taught to physics majors in US institutions

Author: Patricia Heller, Azin Adjoudani, James S. Terwilliger, and J. W. Halley
Subjects: Physics, Mathematics education, General Physics and Astronomy, Modern physics, Engineering physics, Curriculum
Abstract: A study is described to evaluate the Graduate Record Examination (GRE) as an indicator of learning by undergraduate physics majors. Measures were obtained of the overlap of the Graduate Record Examination in physics with the curriculum as it is taught to physics majors in US colleges and universities. The output of the project, for a given subfield f and set j of institutions, was two numbers Rj, f1 and Rj, f2. These two numbers estimated the extent to which (1) for Rj, f1, the curriculum prepares students at institutions j to take that part of the GRE which covers subfield f and (2) for Rj, f2, the GRE covers the materials in subfield f taught in the curriculum of institutions j. The subfields f were mechanics, electricity and magnetism, statistical mechanics and thermodynamics, modern physics, and ‘‘other’’ (including experimental, mathematical, and solid‐state physics). The institutions j were grouped into four categories: ‘‘top graduate’’ (those with the 20 best‐ranked graduate programs); ‘‘top under...

Abstract: We studied the transport properties of the Anderson localization model for a disordered metal using a new numerical method in which the time evolution of the current in response to a constant electric field which is turned on abruptly at {ital t}=0 is calculated directly. We report results on the current response of a sample of 128{sup 2} sites in the one-orbital-per-site Anderson model near the metal-insulator transition. We find the current response out to times of the order of 1000 times the inverse bandwidth. We discuss scaling and the values of the critical exponents {nu} and {ital z} (usually thought to be 3).

Subjects: ALEPH Experiment, LEP, supersymmetry
Abstract: Searches for supersymmetric particles in channels with one or more photons and missing energy have been performed with data collected by the ALEPH detector at LEP. The data consist of 11.1 pb-1 at sqrt(s)=161 GeV, 1.1 pb-1 at 170 GeV and 9.5 pb-1 at 172 GeV. The e+e--->νν¯γ(γ) cross section is measured. The data are in good agreement with predictions based on the Standard Model, and are used to set upper limits on the cross sections for anomalous photon production. These limits are compared to two different SUSY models and used to set limits on the neutralino mass. A limit of 71 GeV/c2 at 95% C.L. is set on the mass of the lightest neutralino (τχ10

Abstract: The triple gauge-boson couplings, αWΦ, αW and αBΦ, have been measured using 34 semileptonically and 54 hadronically decaying W+W- candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb-1. The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W+W- events. The results are in agreement with the Standard Model expectation.

Abstract: The data collected by the ALEPH experiment at LEP at centre-of-mass energies around 183 GeV are analysed to search for sleptons, the partners of leptons in supersymmetric theories. The previously published search for acoplanar leptons and missing energy has been updated. New searches have been developed to cover a wider range of slepton signals. These include single electrons, acoplanar leptons accompanied by two photons plus missing energy as well as particles with lifetime. No evidence for the production of any such particles is found. Slepton mass limits are reported within gravity mediated and gauge mediated SUSY breaking scenarios. (C) 1998 Elsevier Science B.V. All rights reserved.

74. Dome-related gold mineralization in the Pani volcanic complex, North Sulawesi, Indonesia; a study of geologic relations, fluid inclusions, and chlorite compositions

Subjects: geography, geography.geographical_feature_category, Rhyodacite, Geochemistry, Geology, engineering.material, Porphyritic, Volcanic rock, chemistry.chemical_compound, Geophysics, chemistry, Geochemistry and Petrology, engineering, Phenocryst, Economic Geology, Fluid inclusions, Pyrite, Acanthite, Chlorite
Abstract: Gold mineralization at the Pani prospect in north Sulawesi, Indonesia, is related to a Miocene or younger rhyodacitic volcanic center. The center, which is 3.5 km in diameter, consists of porphyritic lavas, intrusions, breccias, and pyroclastics. It overlies and partly intrudes horn-blende and hornblende-biotite granodiorite and Eocene (?) basaltic volcanics.Mineralization is spatially related to the Baganite dome, which is centered on Gunung Baganite. Low-grade (0.8 ppm) disseminated gold mineralization, associated with pyrite and minor base metals, is hosted by the dome. Silver mineralization (acanthite) occurs in minor quartz-hematite veins in overlying silicified pyroclastics. The most important gold mineralization occurs on the flank of the dome at the Pani ridge, less than 1 km from Gunung Baganite. It is associated with minor base metal sulfides, quartz, and adularia encrustations, found in vuggy fractures and centimeter-wide breccia zones, in weakly silicified rhyodacites, and in adjacent wall rocks. Quartz veins on the Pani ridge are virtually absent. The assemblage chloritealbite-anatase-pyrite + or - quartz-adularia is ubiquitous in flow-banded and massive rhyodacites in the prospect area, whereas carbonates occur within the enclosing pyroclastics. Strong silicification occurs in the upper part of the Baganite dome and extends up to 130 m into the overlying volcanics. Adularia veining increases with depth as does secondary K feldspar in the groundmass. The Mg number of chlorite decreases from 60 in the pyroclastics above the Baganite dome to 25 in the rhyodacite at a 300-m depth, and there is significant intrasample variation.Temperatures of chlorite formation in the Baganite dome, calculated from electron microprobe analyses, vary from about 125 degrees to 275 degrees C and are in good agreement with the homogenization temperatures of 150 degrees to 300 degrees C from secondary fluid inclusions in quartz phenocrysts. The salinities of the majority of the fluid inclusions range from near zero up to about 4 equiv wt percent NaCl, but some salinities are as high as 40 equiv wt percent. Vapor-rich inclusions also occur. The redox states of the fluids associated with the Baganite dome, calculated from chlorite compositions, varied significantly, from about -2 to -8 log f (sub O 2 ) units below the hematite-magnetite buffer. Hydrogen sulfide levels in the fluids decreased from a maximum of 30 ppm around 250 degrees C, with decreasing temperature and oxidation state, and pH values were close to neutrality.Gold was apparently transported at 1-ppb levels at the highest temperature in the most oxidized fluids, of around 4 equiv wt percent NaCl salinity, which probably rose through the root zones and the lower contacts of the Baganite dome. Gold precipitated as the fluids cooled by boiling (indicated by vapor-rich inclusions, adularia, and Mg-rich chlorites) and also by mixing with low-salinity, reduced fluids inferred to have circulated around the flanks of the dome. The latter mechanism was probably the most efficient and suggests that there may be potential on the margins of volcanic domes for large-tonnage, low-grade gold deposits.

75. Scaling at the rod-to-flexible chain crossover in the stiff limit

Abstract: The authors critically examine the present theoretical understanding of the conformational rod-to-flexible chain crossover of a linear chain polymer in dilute solution with a good solvent. There is good evidence for weak universality in this crossover while strong universality seems unlikely from available evidence. In addition, this system should exhibit a second crossover from a Gaussian to an excluded volume. They present a scaling hypothesis for the behaviour of this second crossover and compare with the initial results of numerical simulations and with the experiment of Murakami et al. (1980).

Abstract: The Aleph detector is installed on the LEP electron-positron storage ring. Its central tracking detector, a time projection chamber (TPC), has about 50000 channels of sampling electronics. The digitized signals are processed by 72 double-width Fastbus modules built around an MC 68020 processor. The time projection processor is described, and the solutions, both hardware and software, adopted to run and manage such a complex system in a Fastbus-VAX environment are discussed. Practical experience with the system is reported. >

Abstract: We report calculations of the electronic structure of a model of ${\mathrm{TiO}}_{2}$ which contains oxygen vacancies. The model uses the full tight-binding model of Vos. We use a screened Coulomb potential and a soft positive core to describe the oxygen vacancy. We study the electronic density of states as a function of the thickness of a layer of ${\mathrm{TiO}}_{2}$ and of the number of oxygen vacancies up to 10% vacancies. We show that the structure of the density of states in the neighborhood of the conduction-band edge cannot be even approximately described by a crystal-field calculation involving only a few metal ions near the vacancy. The evolution of the density of states as the layer is made thicker is described.

Abstract: Operation of the time projection chamber of the ALEPH experiment at LEP requires a high-purity argon/methane gas mixture supplied to the detector under stable conditions to ensure minimum signal attenuation throughout the 43 m 3 detector volume (max. 2.2 m drift length) and maintain near-constant electron drift velocity in the gas over extended periods of time. Design considerations for a gas system to fulfil these conditions are presented and details given of the construction, operational aspects and of the achieved performance.

79. Molecular dynamics model of absorption of water in polymers

Author: J. W. Halley and J. L. Vallés
Subjects: chemistry.chemical_classification, Absorption of water, General Physics and Astronomy, Infrared spectroscopy, Polymer, Molecular dynamics, chemistry, Chemical physics, Water model, Organic chemistry, Molecule, Physics::Chemical Physics, Physical and Theoretical Chemistry, Absorption (chemistry), Physics::Atmospheric and Oceanic Physics, Repeat unit
Abstract: We report a molecular dynamics simulation of the absorption of water in polymers. We embed a relatively large repeat unit containing several characteristic chemical groups in a molecular dynamics model of water which includes the internal dynamics of the water molecule. Potentials describing the interaction of the water with the repeat unit were taken from the work of Jorgensen and co‐workers. We calculated the density of water around oxygen in ester, ether and alcohol groups in the repeat unit. We find in this model that the water is only bound by the alcohol group in agreement with recent experimental results. We have computed the infrared absorption spectrum of the bound and unbound water in this model. We find shifts which should be observable in the position of the stretch and librational frequencies due to binding of the water. We discuss implications for the dual diffusion model of water in polymers.

Abstract: We show that very low velocity droplets can be used to carry out an experiment to test whether condensate mediated transmission processes can occur in a superfluid droplet of $^{4}\mathrm{He}$. By appropriately choosing the droplet radius and temperature, we can eliminate the competing roton, phonon, and ripplon mediated elastic transmission events. Then a calculation shows that if a few percent or more of the incident atoms experience anomalous condensate mediated transmission, the effects should be detectable in the droplet trajectories. We consider two forms of the experiment, involving a freely falling droplet in ambient vapor in the first instance and an oscillating droplet in a magnetic trap in the second.

Abstract: Indirect limits on the mass of the lightest neutralino are derived from the results of searches for charginos, neutralinos, and sleptons performed with data taken by the ALEPH Collaboration at centre-of-mass energies near the Z peak and at 130 and 136 GeV. Within the context of the Minimal Supersymmetric Standard Model and when $M_{\tilde\nu}\ge 200$ GeV/c^2, the bound $M_\chi>12.8$ GeV/c^2 at the 95\% confidence level applies for any $\tan\beta$. The impact of lighter sneutrinos is presented in the framework of SUSY grand unified theories; a massless neutralino is allowed only for a narrow range of $\tan\beta$, $\mu$, and the scalar mass parameter $m_0$. Finally, by including Higgs mass constraints and requiring that radiative electroweak symmetry breaking occur, more stringent bounds on $M_\chi$ as a function of $\tan\beta$ are derived., Comment: 26 pages, one latex file and 15 eps figures

Subjects: ALEPH Experiment
Abstract: Searches for charginos and neutralinos produced in e+e- collisions at centre-of-mass energies of 130 and 136 GeV have been performed under the assumptions that R-parity is not conserved, that the dominant R-parity violating coupling involves only leptonic fields, and that the lifetime of the lightest supersymmetric particle can be neglected. In the 5.7 pb-1 data sample collected by ALEPH, no candidate events were found. As a result, chargino and neutralino masses and couplings are constrained and the domains previously excluded at LEP1 are extended.

Abstract: The electroweak mixing angle is determined with high precision from measurements of the mean difference between forward and backward hemisphere charges in hadronic decays of the Z. A data sample of 2.5 million hadronic Z decays recorded over the period 1990 to 1994 in the ALEPH detector at LEP is used. The mean charge separation between event hemispheres containing the original quark and antiquark is measured for b (b) over bar and c (c) over bar events in subsamples selected by their long lifetimes or using fast D*'s. The corresponding average charge separation for light quarks is measured in an inclusive sample from the anticorrelation between charges of opposite hemispheres and agrees with predictions of hadronisation models with a precision of 2%. It is shown that differences between light quark charge separations and the measured average can be determined using hadronisation models, with systematic uncertainties con strained by measurements of inclusive production of kaons, protons and Lambda's. The separations are used to measure the electroweak mixing angle precisely as sin(2) theta(w)(eff) = 0.2322 +/- 0.0008(exp. stat.) +/-0.0007(exp. syst.) +/- 0.0008(sep.). The first two errors are due to purely experimental sources whereas the third stems from uncertainties in the quark charge separations.

Abstract: The lifetimes of the B 0 and B + mesons have been measured with the Aleph detector at LEP, using approximately 3 million hadronic Z decays collected in the period 1991 1994. In the first of three methods, semileptonic decays of B 0 and B + mesons were partially reconstructed by identifying events containing a lepton with an associated D*- orbar D^0 meson. The second method used fully reconstructed B 0 and B + mesons. The third method, used to measure the B 0 lifetime, employed a partial reconstruction technique to identify B 0→ D*- π + X decays. The combined results are begin{gathered} tau _0 = 1.55 ± 0.06 ± 0.03 ps, \ tau _ + = 1.58 ± 0.09 ± 0.03 ps, \ tfrac{{tau _ + }}{{tau _0 }} = 1.03 ± 0.08 ± 0.02.

87. Modeling the structure and electronic properties ofTiO2nanoparticles

Author: Yongjing Lin, James W. Halley, Amanda S. Barnard, Serkan Erdin, and Peter Zapol
Subjects: Anatase, Materials science, Chemical physics, Nanoparticle, Nanotechnology, Density functional theory, Electronic structure, Electron, Condensed Matter Physics, Energy minimization, Electron localization function, Electronic, Optical and Magnetic Materials, Electronic properties
Abstract: A self-consistent tight-binding method and density functional theory were used to study structures and electronic properties of anatase nanoparticles. Full geometry optimization resulted in both surface relaxation and a slight overall contraction of the nanoparticles. Analyzing electronic properties using electron localization function and Mulliken populations, we found nonbonding electrons at the edges and corners of the nanoparticle. The results of tight-binding and density functional theory calculations are in good agreement, suggesting the tight-binding scheme to be a useful tool for studies of larger nanoparticles in the range of hundreds to thousands of atoms. The self-consistent tight-binding results on nanoparticles of sizes up to 1365 atoms and some structural, electronic, and energetic trends as a function of nanoparticle size are also reported.

88. Computational Studies in Molecular Geochemistry and Biogeochemistry

Abstract: The ability to predict the transport and transformations of contaminants within the subsurface is critical for decisions on virtually every waste disposal option facing the Department of Energy (DOE), from remediation technologies such as in situ bioremediation to evaluations of the safety of nuclear waste repositories. With this fact in mind, the DOE has recently sponsored a series of workshops on the development of a Strategic Simulation Plan on applications of high perform-ance computing to national problems of significance to the DOE. One of the areas selected for application was in the area of subsurface transport and environmental chemistry. Within the SSP on subsurface transport and environmental chemistry several areas were identified where applications of high performance computing could potentially significantly advance our knowledge of contaminant fate and transport. Within each of these areas molecular level simulations were specifically identified as a key capability necessary for the development of a fundamental mechanistic understanding of complex biogeochemical processes. This effort consists of a series of specific molecular level simulations and program development in four key areas of geochemistry/biogeochemistry (i.e., aqueous hydrolysis, redox chemistry, mineral surface interactions, and microbial surface properties). By addressing these four differ-ent, but computationally related, areas it becomes possible to assemble a team of investigators with the necessary expertise in high performance computing, molecular simulation, and geochemistry/biogeochemistry to make significant progress in each area. The specific targeted geochemical/biogeochemical issues include: Microbial surface mediated processes: the effects of lipopolysacchardies present on gram-negative bacteria. Environmental redox chemistry: Dechlorination pathways of carbon tetrachloride and other polychlorinated compounds in the subsurface. Mineral surface interactions: Describing surfaces at multiple scales with realistic surface functional groups Aqueous Hydrolysis Reactions and Solvation of Highly Charged Species: Understanding the formation of polymerized species and ore formation under extreme (Hanford Vadose Zone and geothermo) conditions. By understanding on a fundamental basis these key issues, it is anticipated that the impacts of this research will be extendable to a wide range of biogeochemical issues. Taken in total such an effort truly represents a “Grand Challenge” in molecular geochemistry and biogeochemistry.

Subjects: ALEPH Experiment, Physics
Abstract: The branching fraction of Z --> bb relative to all hadronic decays of the Z has been measured using event shape variables to preferentially select Z --> bb events. The method chosen applies a combination of shape discriminators and the selection of high transverse momentum leptons to event hemispheres. From a sample of 440 000 hadronic Z decays collected with the ALEPH detector at LEP, the ration Γbb/Γhad = 0.228+/-0.005(stat.)+/-0.005(syst.) is measured.

Abstract: A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209GeV. An excess of 3sigma beyond the background expectation is found, consistent with the production of the Higgs boson with a mass near 114GeV/c2. Much of this excess is seen in the four-jet analyses, where three high purity events are selected., Comment: 16 pages, 13 figures

Abstract: We calculate the scattering states and cross sections for a Bose-Einstein condensed dilute gas trapped in a spherical square well of finite depth. The interactions are treated in the scattering length approximation. We solve the Gross-Pitaevskii equation and the Bogoliubov equations for bound and scattering states. The results show that there are transparency effects reminiscent of those conjectured to occur for strongly coupled systems. When incident particle wavelengths λ are comparable to the well size a, exchange induced transparency enhancement is dramatic only for particular combinations of well depth, interaction strength, and particle number. For particles with large momenta (a/λ≫1),however, exchange with the condensate results in enhanced transmission for all coupling strengths. We calculated the rate of decay of the scattering states to leading order in anharmonic corrections to the Bogoliubov approximation and found the corresponding inelastic cross sections to be extremely small.

Abstract: Data collected at centre-of-mass energies from 189 GeV to 202 GeV by the ALEPH detector at LEP corresponding to an integrated luminosity of 411 pb(-1), are analysed in a search for the scalar top in the decay channels (t) over tilde --> c/u chi for small mass differences between the stop and the lightest neutralino. No evidence for deviations from the Standard Model expectation is found and a lower limit of 59 GeV/c(2) is set for the stop mass, independent of the stop to neutralino mass difference and of the stop lifetime.

95. Simulation Studies of Polymer Electrolytes for Battery Applications

Author: J. W. Halley and B. Nielsen
Subjects: Battery (electricity), chemistry.chemical_classification, Work (thermodynamics), Materials science, chemistry, Chemical physics, Inorganic chemistry, Fast ion conductor, Ionic conductivity, Polymer, Conductivity, Thermal conduction, Amorphous solid
Abstract: We report modeling studies of polyethylene oxide which are carried out with the goal of elucidating the mechanism of ion conduction in the temperature range of interest to battery applications. We review our previous work in which the amorphous regions of the polymer between its glass and melting temperatures is modeled by a molecular dynamics algorithm in which the model system is polymerized from a model monomeric liquid. We describe new work in which the hydrogen centers are added to the model in order to permit comparison with recent neutron work. We compare our simulations of frequency dependent conductivity with experiment and end with a brief discussion of possibilities for improved conductivity which our current understanding suggests.

96. Ewald methods for polarizable surfaces with application to hydroxylation and hydrogen bonding on the (012) and (001) surfaces of alpha-Fe2O3

Abstract: We present a clear and rigorous derivation of the Ewald-like method for calculation of the electrostatic energy of the systems infinitely periodic in two-dimensions and of finite size in the third dimension (slabs) which is significantly faster than existing methods. Molecular dynamics simulations using the transferable/polarizable model by Rustad et al. were applied to study the surface relaxation of the nonhydroxylated, hydroxylated, and solvated surfaces of alpha-Fe2O3 (hematite). We find that our nonhydroxylated structures and energies are in good agreement with previous LDA calculations on alpha-alumina by Manassidis et al. [Surf. Sci. Lett. 285, L517, 1993]. Using the results of molecular dynamics simulations of solvated interfaces, we define end-member hydroxylated-hydrated states for the surfaces which are used in energy minimization calculations. We find that hydration has a small effect on the surface structure, but that hydroxylation has a significant effect. Our calculations, both for gas-phase and solution-phase adsorption, predict a greater amount of hydroxylation for the (012) surface than for the (001) surface. Our simulations also indicate the presence of four-fold coordinated iron ions on the (001) surface., Comment: 23 pages, REVTeX (LaTeX), 8 figures not included, e-mail to evgeny@boys.pnl.gov, paper accepted in Surface Science

Abstract: A sample of 3.6 million hadronic Z decays recorded between 1991 and 1995 with the ALEPH detector at LEP is used to investigate semileptonic decays of B mesons into final states involving orbitally excited charm mesons. Topological vertex criteria are used to search for decays involving narrow D** states as well as wide D** resonances and non-resonant D(*)pi final states. The sum of the branching ratios for these processes is measured to be Br((B) over bar --> D pi l(-)(v) over bar) + Br((B) over bar --> D*pi l(-)(v) over bar) = (2.26 +/-t 0.29(stat) +/- 0.33(syst))%, which accounts for a significant fraction of the deficit between inclusive measurements and the sum of exclusive semileptonic B decay modes.

Abstract: A new Silicon Vertex Detector was developed for the ALEPH experiment and first installed for the high energy run at 130 GeV at the end of 1995. The detector has an active length of 40 cm and consists of two concentric layers of silicon wafers with double-sided readout. It extends the angular coverage, has only half the passive material as the former detector in the tracking volume and is radiation hard to cope with the higher level of radiation background expected for the LEP2 phase. The construction and the performance of the detector is described.

Abstract: Data on the inclusive production of the neutral vector mesons rho(0)(770), omega(782), K*(0)(892), and phi (1020) in hadronic Z decays recorded with the ALEPH detector at LEP are presented and compared to Monte Carlo model predictions. Bose-Einstein effects are found to be important in extracting a reliable value for the p(0) production rate. An average p(0) multiplicity of 1.45 +/- 0.21 per event is obtained. The omega is detected via its three pion decay mode omega --> pi(+)pi(-)pi(0) and has a total rate of 1.07 +/- 0.14 per event. The multiplicity of the K*(0) is 0.83 +/- 0.09, whilst that of the phi is 0.122 +/- 0.009, both measured using their charged decay modes. The measurements provide information on the relative production rates of vector and pseudoscalar mesons, as well as on the relative probabilities for the production of hadrons containing u, d, and s quarks.

Abstract: A data sample of about 3.0 million hadronicZ decays collected by the ALEPH experiment at LEP in the years 1991 through 1994 is used to make an inclusive selection of B hadron events. In this event sample 4227±140±252B* mesons in the decayB*→Bγ and 1944±108±161B** u,d mesons decaying into a B meson and a charged pion are reconstructed. Here and in the followingB** u,d denotes the eightL=1(bū) and (bd) states and their charge conjugate. For the well establishedB* meson the following quantities are obtained:ΔM=M B*−MB=(45.30±0.35±0.87) MeV/c2 andN B*/(N B+N B*)=(77.1±2.6±7.0)%. The angular distribution of the photons in theB* rest frame is used to measure the relative contribution of longitudinalB* polarization states to beσ L/(σ L+σ T)=(33±6±5)%. In theM(Bπ)−M(B) mass difference resonance structure is observed at (424±4±10) MeV/c2, for which the shape and position is consistent with the expectation forB** u,d states decaying intoB(*)π ±. The relative production rate is determined to be $$\begin{gathered} \frac{{BR(Z \to b \to B_{u,d}^{ * * } )}}{{BR(Z \to b \to B_{u,d} )}} \hfill \\ = [27.9 \pm 1.6(stat) \pm 5.9(syst) {}_{ - 5.6}^{ + 3.9} (model)]\% \hfill \\ \end{gathered} $$ where the third error reflects the uncertainty due to different production and decay models for the broadB** u,d states.
