Utilization of Chemical Structure Information for Analysis of Spectra Composites
In this paper, we propose the utilization of structural information of spectral data during the preprocessing to extend the ability of subsequent analysis methods. Specifically, we expect a dataset of measured spectra containing mixtures of only a few spectral components. Using the concentration ratios for a small subset of mixtures and the chemical structural knowledge, theoretical spectral co...
متن کاملChemical Environment Selectivity in Mössbauer Diffraction from 57 Fe 3
T. A. Stephens and B. Fultz Division of Engineering and Applied Science, mail 138-78, California Institute of Technology, Pasadena, California 91125 (Received 5 March 1996) Mössbauer diffraction was used to measure different autocorrelation functions for 57Fe atoms in different chemical environments. The sample was polycrystalline Fe3Al with the ordered DO3 structure. Diffraction peaks from a f...
متن کاملSoft Soil Seismic Design Spectra Including Soil-structure Interaction
Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...
متن کاملDesulfovibrio vulgaris hydrogenase: a nonheme iron enzyme lacking nickel that exhibits anomalous EPR and Mössbauer spectra.
A purification procedure for the periplasmic hydrogenase from Desulfovibrio vulgaris ( Hildenborough , National Collection of Industrial Bacteria 8303) is reported. The purified hydrogenase has a specific activity of 4800 units per mg of protein. Plasma emission studies reveal that this highly active hydrogenase is free of nickel and contains 11 (+/- 1) nonheme iron atoms per molecule. A combin...
