AU - Lucovsky, G. AU - Whitten, J.L. T2 - Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures AB - An important issue in semiconductor device operation is the rate at which current or voltage stress creates defects that can eventually degrade device operation. Based on recent results on nitrided gate dielectrics, we have concluded that bonded-H at the Si–SiO2 interface plays a role in the formation of metastable defects that can be activated, and subsequently neutralized, by sequential trapping of injected holes and electrons. In this article, differences in defect behavior for Si–SiO2 interfaces that have been exposed to nitrogen (N-) atoms or N–H groups are discussed. Based on these results, a microscopic model for interfacial defects is proposed.

T2 - The Journal of Chemical Physics AB - The present work studies the symmetric and asymmetric pathways of the recombinative desorption of molecular hydrogen from the monohydride Si(100)-2×1H surface by the cluster method. The transition states are searched at the self-consistent-field and multiconfiguration self-consistent-field levels of theory and the energies are calculated at the configuration interaction level of theory. For the asymmetric transition state, the structure determined at the self-consistent-field level is similar to that determined at the multiconfiguration self-consistent-field level. However, for the symmetric transition state, electron correlation is found to play such a crucial role that multiconfiguration self-consistent-field theory has to be used to obtain the saddle point. At the configuration interaction level of theory, the activation energies for the symmetric and asymmetric pathways are computed to be 86.3 and 85.0 kcal/mol, respectively. Compared with the experimental values of 45-66 kcal/mol, the large barriers suggest that the direct desorption mechanism is not applicable. A multistep desorption mechanism which involves a delocalized process in the formation of dihydride SiH2 and a localized desorption of H2 has been proposed to explain the experimental observations.

AU - Jing, Z. AU - Lu, Z. AU - Lee, D.R. AU - Whitten, J.L. T2 - Journal of Non-Crystalline Solids AB - This paper discusses bonding configurations of hydrogen atoms (H) in amorphous silicon and amorphous-silicon-based alloys. Recent experiments combined with theoretical calculations have identified two new aspects of bonded H that have not previously been addressed: (i) the formation of H bonds between H atoms on SiH groups and electronegative atoms or groups such as O atoms or NH groups; and (ii) an inherent metastability of H-bonded clusters as driven by the trapping of charged carriers. Both of these are shown to play important roles in (i) a photo-induced defect metastability such as the Staebler-Wronski effect, and (ii) hydrogen evolution from amorphous silicon nitrides. Finally, the concepts developed for a-Si:H alloys apply equally well to defect metastability at SiSiO2 interfaces as in metal-oxide-semiconductor devices including insulated-gate field-effect transistors.

AU - Whitten, Jerry L. T2 - The Journal of Chemical Physics AB - The adsorption of cyanide (CN) on Ni(111) is treated using an ab initio embedding theory. The Ni(111) surface is modeled as a three-layer, 28-atom cluster with the Ni atoms fixed at bulk lattice sites. The present calculations show that CN is able to bind to the surface either via the carbon, or nitrogen, or in a side-on geometry with very small differences in total energy (≊0.1 eV). Adsorption energies at threefold, bridge and atop sites are comparable, with the fcc threefold site more favorable over other adsorption sites by ≊0.1 eV. At the fcc threefold site, adsorption energies and C–N stretching frequencies are 5.0 eV and 2150 cm−1 for the η1-cyanide-N, 4.9 eV and 1970 cm−1 for the η1-cyanide-C, and 4.9 eV and 1840 cm−1 for the η2-cyanide-C,N, respectively. Dipole moment calculations show that the bonding of CN to the Ni surface is largely ionic, while η2-cyanide-C,N has more covalent character. Calculated energy barriers in going from η1-cyanide-C to η2-cyanide-C,N, and from η2-cyanide-C,N to η1-cyanide-N are around 0.1 eV. Thus although CN is strongly bound to the surface (at ≊5 eV), within an energy range of ≊0.2 eV, the molecule is free to rotate to other geometries. During this rotation there are large changes in the dipole moment.

T2 - Surface Science AB - Ab initio configuration interaction calculations are performed to study the chemisorption of atomic H on a Fe(110) surface. The lattice is modeled as an embedded three-layer, 40-atom cluster with the Fe atoms fixed at the bulk position. Fe 3d orbitals are explicitly included on five Fe atoms on the surface. Hydrogen strongly binds to the Fe(110) surface at the long-bridge, short-bridge, and quasi three-fold sites. The calculated adsorption energies are 2.76, 2.73, and 2.71 eV, respectively. H-surface bonding at the on-top Fe site is more than 0.4 eV weaker. The calculated H-surface distances are 0.89, 1.03, and 0.87Åfor H at the long-bridge, short-bridge, and quasi three-fold sites, respectively, which agrees well with the LEED value of 0.9 ± 0.1Å. The H-surface stretching vibrational frequencies are calculated to be 1070, 1066, and 1073 cm−1, at the long-bridge, short-bridge, and quasi three-fold sites, respectively. The work function of Fe(110) decreases on H adsorption. The present calculations indicate that H diffusion into the bulk through the short-bridge site will have a much higher activation barrier than via the long-bridge and quasi three-fold sites.

AU - Gusev, Arkady I. AU - Stoppek-Langner, Karl AU - Proctor, Andrew AU - Hercules, David M. AU - Tata, Prasad AU - Venkataramanan, Raman AU - Diven, Warren T2 - Journal of Mass Spectrometry AB - Abstract Simultaneous quantification of cyclosporin A (CsA) and its major metabolite (AM1) in blood has been achieved using time‐of‐flight secondary‐ion mass spectrometry (TOF‐SIMS) and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI/TOF‐MS). Previous investigations indicated that spectral interferences exist in the analysis of CsA blood samples by the above methods. In TOF‐SIMS, interference is caused by overlap of the Ag‐cationized internal standard, cyclosporin D (CsD), with the Ag‐cationized metabolite, AM1. To resolve this interference and obtain quantitative information, cross‐correlation analysis was applied to the TOF‐SIMS data. Application of damped non‐linear least squares curve‐fitting was carried out to resolve an interference in the MALDI/TOF‐MS data due to multiple cationization products (i.e. Na and K). Measurement of standard samples indicates that the minimum accuracy (95% confidence level) of the TOF‐SIMS method was better than 9% for CsA and 13% for AM1 using only one standard curve'. Similarly, the minimum accuracy of the MALDI/TOF‐MS method was determined to be 14% for CsA and better than 25% for AM1. Blood samples obtained from transplant patients receiving CsA were analyzed by polyclonal fluorescence polarization immunoassay, high‐performance liquid chromatography (HPLC), and by both TOF‐MS methods. Both TOF‐MS results for CsA and mono‐hydroxylated CsA are in good agreement with the HPLC results.

T2 - Mass Spectrometry Reviews AB - This review primarily focuses on the current status of two solid-state mass spectrometric (MS) techniques, namely, static secondary-ion (SIMS) and matrix-assisted laser desorption-ionization (MALDI) time-of-fight (TOF) maSs spectrometry, as applied to the quantification of biological materials. Although a number of articles have appeared in the literature for both SIMS and MALDI quantitative analysis, neither field has been extensively researched nor currently used in general practice. However, several results are very exciting and offer advantages over conventional methods. The abilities and limitations of MALDI and SIMS for quantitative analysis of biological molecules will be discussed at the fundamental and applied level. Use of an internal standard approach, development of instrumental protocols, and sample preparation will be examined in detail. Various examples demonstrating the feasibility of quantitative analysis by MALDI and SIMS, including quantification of in vivo and in vitro metabolism of drugs in real biological matrices, will be reviewed. © 1996 John Wiley & Sons, Inc.

T2 - Science AB - Emission indices of reactive gases and particles were determined from measurements in the exhaust plume of a Concorde aircraft cruising at supersonic speeds in the stratosphere. Values for NOx (sum of NO and NO2) agree well with ground-based estimates. Measurements of NOx and HOx indicate a limited role for nitric acid in the plume. The large number of submicrometer particles measured implies efficient conversion of fuel sulfur to sulfuric acid in the engine or at emission. A new fleet of supersonic aircraft with similar particle emissions would significantly increase stratospheric aerosol surface areas and may increase ozone loss above that expected for NOx emissions alone.

AU - Malak, H. AU - Gryczynski, I. AU - Castellano, F.N. AU - Meyer, G.J. T2 - Biospectroscopy AB - Abstract Measurements of DNA dynamics are typically limited to the nanosecond timescale because of the nanosecond decay times of commonly used fluorophores such as ethidium bromide and acridine derivatives. We show that the time‐resolved anisotropy measurements can be extended to the submicrosecond timescale using metal‐ligand complexes. The ruthenium complex [Ru(2,2′,‐bipyridine) 2 (dipyrido[3,2‐a : 2′,3′‐c]phenazine)] 2+ , or [Ru(bpy) 2 (dppz)] 2+ , was found to display high anisotropy near 0.2, at −60°C in 100% glycerol, when excited in its long‐wavelength absorption bands. The decay time of [Ru(bpy) 2 (dppz)] 2+ when bound to DNA is over 100 ns, allowing intensity to be measured to over 400 ns. Other Ru complexes display still longer lifetimes to 750 ns when bound to DNA. This class of fluorophores should enable measurement of DNA dynamics over a wide range of times (from 1 ns to several μs), which were previously inaccessible using time‐resolved fluorescence. © 1995 John Wiley & Sons, Inc.

AU - Belford, R.L. T2 - Journal of Magnetic Resonance, Series A AB - An inhomogeneous lineshape model based on a convolution of Gaussian and Lorentzian functions is very common in EPR spectroscopy. For convenience, the convolution integral often is approximated by a sum of Gaussian and Lorentzian functions. A more accurate and general approach to linewidth simulation and fitting by use of a fast convolution algorithm is described. A Levenberg-Marquardt method is applied in the multidimensional optimization of simulation parameters. The partial-derivative matrix required for the Levenberg-Marquardt procedure is calculated without digital differentiation. To account for a microwave shift observed in 94 and 1.1 GHz EPR experiments, a dispersion parameter is included in the fitting function. All fitting parameters, including Lorentzian and Gaussian components to the linewidth, microwave phase shift, resonance position, and intensity, are extracted from experimental spectra directly. A fixed and/or variable superhyperfine pattern (or envelope function) may be included in the fitting procedure without a significant increase in computational time. Three examples of this technique are shown: extraction of Lorentzian broadening for a nitroxide EPR spectrum at various oxygen concentrations, penetration of a 1.1 GHz microwave field into a lossy dielectric sample, and processing of a mixed absorption-dispersion nitroxide 94 GHz EPR spectrum in the fast-motion limit.

AU - Norby, S.W. AU - Smirnov, A. AU - Boyer, S. AU - Vahidi, N. AU - Nims, R.W. AU - Wink, D.A. T2 - BBA - General Subjects AB - We have developed an electron paramagnetic resonance (EPR) method for the nondestructive detection and quantification of intracellular NO in real time. Based upon this technique, we have obtained evidence for the metabolism of this bioregulatory molecule by mitochondria. Line-broadening of the EPR signal of a coal derivative, fusinite, was calibrated as a function of NO concentration in aqueous solution. The methodology was validated using two compounds which release NO in a controlled and predictable manner with first-order rate constants k1 = 5.0 x 0.10(-3) s-1 and k'1 = 3.4 x 10(-4) s-1 (35 degrees C). Fusinite was internalized in Chinese hamster ovary cells (CHO) by phagocytosis, after which the cells were allowed to consume the available O2, producing an hypoxic environment. The NO released from one of the NO donors, added to the culture fluid at an initial concentration of 50 microM, was directly measured in the intracellular environment as line-broadening of the fusinite EPR signal. The linewidth diminished with time, indicating that NO was being converted to a non-paramagnetic species by the cells with an apparent zero-order rate constant of 5 x 10(8) NO molecules cell-1 min-1 (20 degrees C). Addition of cyanide to the culture medium (5 mM final concentration) inhibited this disappearance of NO. NO also was converted in the presence of isolated mitochondria in the absence of oxygen. These observations suggest that under hypoxic conditions, there exists in CHO cells a metabolic pathway for the conversion of NO to diamagnetic species, which involves interactions with mitochondria.

AU - Smirnov, Alex I. T2 - Magn. Reson. Chem. AB - Abstract Nitroxide spin labels and probes were applied to measurements of cell redox activities and oxygen concentration by ESR. Current experimental methods often require large numbers of cells and monitoring of only the amplitude of the ESR signal. This can result in experimental artifacts and data misinterpretation. An improved method is described for accurate measurement of nitroxide intensity and linewidth, which in turn provides information about cell redox activities and oxygen concentration. The method is based on fitting of ESR spectra using a fast convolution least‐squares algorithm suitable for inhomogeneously broadened ESR lines. All fitting parameters, including the Lorentzian component of the linewidth and the double integrated intensity, are extracted from the experimental spectra directly. The experiments were carried out at cell concentrations of 5 × 10 6 cell ml −1 or less to prevent cell crowding and at initial nitroxide concentration of 1 mM or 100 μM to ensure that nitroxide metabolism by the cells was not diffusion limited. Examples include experiments with cultured baby hamster kidney and adenovirus transformed hamster cells using the nitroxide radicals TEMPOL (2,2,6,6‐tetramethylpiperidine‐ N ‐oxyl‐4‐ol) and 15 N‐labeled perdeuteriated TEMPONE ( 15 NPDT) (2,2,6,6‐tetramethylpiperidine‐ N ‐oxyl‐4‐one). Under these experimental conditions, the rates of nitroxide metabolism derived from changes in nitroxide intensity are independent of oxygen concentration.

AU - Smirnov, Alex I. AU - Clarkson, Robert B. AU - Belford, R. Linn T2 - Magn. Reson. Med. AB - EPR oximetry is used for in vivo and in vitro measurements of oxygen in biological systems, including experimental animals. The accuracy of oxygen measurements in T2 (line width) EPR oximetry is significantly improved if least-squares simulation is used to extract the line width parameters. The oxygen effect on the EPR spectra of nitroxide solutions and aqueous suspensions of fusinite can be described as an additional homogeneous broadening that modifies the EPR spectrum of the oxygen-free probe. This allows one to use a one-parameter line width model in most cases. The simulations were carried out with the use of a fast-convolution algorithm followed by Levenberg-Marquardt optimization. The validity of error estimates provided by this method was tested on sets of experimental spectra taken under common conditions. It is shown that the accuracy of oxygen measurements in line width (T2) oximetry is determined not only by the probe sensitivity (rate of line width change versus oxygen concentration), but also by the signal-to-noise ratio, inhomogeneous contribution to the line shape (e.g., unresolved proton superhyperfine structure), and the spectral window. The accuracy of oxygen measurements is compared for aqueous solutions of two nitroxide radicals with different superhyperfine structure and for aqueous suspensions of fusinite.

AU - Scott, Donna L. AU - Bowden, Edmond F. AU - Daub, Margaret E. T2 - Photochemistry and Photobiology AB - Abstract Fungi in the genus Cercospora produce a singlet‐oxygen‐generating photosensitizing toxin cercosporin, which plays an important role in the ability of these fungi to parasitize plants. Previous studies demonstrated that resistance to cercosporin was associated with the ability of the fungus to reduce and detoxify cercosporin transiently. In order to characterize the mechanism of cercosporin resistance further, two types of mutants were isolated. One set of mutants was selected directly for sensitivity to cercosporin. Six cercosporin‐sensitive mutants were isolated. Five of the mutants were totally inhibited by cercosporin as well as by five other photosensitizers, methylene blue, toluidine blue, eosin Y, rose bengal and hematoporphyrin. These five mutants were also deficient in cercosporin‐reducing ability. The sixth cercosporin‐sensitive mutant was only partially inhibited by cercosporin. This mutant was unaltered in cercosporin‐reducing ability and in its response to the other photosensitizers. In order to test hypotheses concerning the mechanism of cercosporin reduction, a second set of mutants was selected for general deficiency in cell surface‐reducing capability by screening for the inability to reduce two tetrazolium dyes ( p ‐tolyltetrazolium red and 2,3,5‐triphenyltetrazolium chloride) of similar redox potential to cercosporin. Dye‐reduction‐deficient mutants were unaltered in their resistance to cercosporin and in cercosporin‐reducing ability. We conclude that cercosporin resistance of these fungi is strongly correlated with the ability to reduce cercosporin. However, cercosporin‐reducing ability is separable from the general ability to reduce external electron acceptors.

Higher (1.07×10 -2 M) and lower (4.49×10 -4 M) initial concentrations were studied. At the higher substrate concentration, the quantum yields for the disappearance of I (Φ0.30) and for the generation of chloride ions (Φ0.25) were independent of the dissolved gas (O 2 - or N 2 -saturated). It is also of interest that a significant amount of 4-chlorocatechol was generated at this higher substrate concentration. Finding 4-chlorocatechol is a new result for the direct photolysis of I in the absence of added H 2 O 2 . For the lower substrate concentration, the average quantum yields for the initial disappearance of I (Φ0.55) and for the initial generation of chloride ions (Φ0.45) were both larger than the quantum yields obtained with the higher substrate concentration. It was found beyond the initial radiation times (n>3×10 20 photons absorbed by the solutions), that the dechlorination of I in the O 2 -saturated solutions was slightly more efficient than the N 2 -saturated solutions, whereas initially they were approximately the same for both the O 2 - and N 2 -saturated solutions. Different products from the dechlorination of I were observed depending on the initial substrate concentration. At the higher initial substrate concentration, the major products from the dechlorination of I were oligomers. At the lower initial substrate concentration, hydroquinone was the major product in O 2 -saturated solutions, but oligomers were still the major product when these solutions were N 2 -saturated.

T2 - Journal of Applied Poultry Research AB - The objective of this study is to quantify the economic importance of the poultry industry to the economy of North Carolina. As a first step, an industry survey was conducted to collect production and marketing statistics at the farm and processing levels. In addition, total industry employment, number of contract growers and contract payments, and the intra- and inter- industry flows of goods and services were recorded. Using the survey results, region input/output analysis was performed to estimate the economic impact of the North Carolina poultry industry on total state production, income, and employment. Results show that the poultry industry as a whole supports almost 52,000 jobs and generates almost $1.6 billion in state income. Stated alternatively, the study shows that for every dollar of income earned by poultry processing firms, three dollars are generated across the state's economy, and for every person hired by a poultry processing facility, employment across the state increases by 2.92 persons.
