Carbon-based compounds are the basis for all living systems and comprise the structure of fossil fuels in the form of hydrocarbons. Several carbon isotopes are important. The International Union of Pure and Applied Chemistry designated the isotope C-12 as the basis for atomic weights, whi...

The precursors used were molybdenum, bismuth, indium, triethanolamine in complex form and sodium selenosulphite as a source of Mo4+, Bi3+, In3+ and Se2 along with organic additives, respectively. The...doi:10.1139/v11-107S. M. Patil...
The "E Tougaard" or "E" background type is such a simplification, where the loss functional form is a Gaussian. The parameters in the cross-section list are the Gaussian height, full-width-half-maximum, exponential tail parameter and an offset to the Gaussian. The exponential tail is ...
Full size image The present study benefitted from the unique suite of soil samples virtually differing only in soil age and particle surface elemental composition that allowed observing and quantifying BGI formation. XPS with an analysis depth close to CA analysis depth, in fact, proved to be a...
The rich chemistry often detected in star forming regions is now recognized to be a consequence of solid-state astrochemistry and the thermal desorption of its products. In recent experimental studies, desorption of a range of ices from ... WA Brown,S Viti,AJ Wolff,... - 《Faraday Discussio...
The spot size in the measurement was 3 x 1mm. The use of dispersion compensation yielded the instrumental resolution of 0.5 eV with full width at half-maximum on the Ag3d line of silver. Multiple scan averaging on a multi- channel analyzer helped to guarantee accurate data for the valence ...

Further, the peak model must account for carbon chemistry not shown in Figure Text1 which is often assumed to be contamination by adventitious carbon or some form of degradation to the sample incurred before commencement of the current experiment. 70 60 Residual STD = 0.9821 50 40 30 20 10 ...
in the presence of ethanol under full film lubrication, due to the reduction in the lubricant's viscosity, but under boundary lubrication friction was higher for oils contaminated with ethanol [17]. Since those results suggested an interaction of ethanol with the anti-wear additive present in the...
