A series of cobalt-molybdenum-alumina catalysts was fabricated using as carriers λ-Al2O3 doped with various amounts of sodium. Over these surfaces the H.D.S. of thiophene has been studied. A considerable decrease in the catalytic activity was observ

The conditions at which sodium used as a dope can modify the state of dispersion and nature of γ-alumina supported cobalt oxide are investigated. The order of impregnation and the temperature of calcination after Na impregnation are shown to be esse

With respect to sustainable development, the leachability of trace metal from solid materials in contact with water has focused much attention over the years. Portland cements produced in industrial kilns generally contain from 10 to 300 mg/kg of tra

The I/V characteristics of polycrystalline CdS under illumination in an aqueous basic solution are improved after photoetching by cysteine. These improvements are not correlated to changes in the morphology of the CdS surface nor to incorporation of

Oil Well Cement (OWC) slurries were studied for their rheological behaviour and sedimentation tendency as a function of dispersant concentration. Adsorption isotherms, zeta potential and sedimentation data indicate that saturation of the surface of c

X-ray photoelectron spectroscopy has been used to determine the N/P concentration ratio in the surface region (30–60 A) of the cell wall of various strains of Saccharomyces cerevisiae and carlbergensis cultured under different conditions. An origin

Mo 3/b d//Al2/b p/ XPS intensity ratios (/b R//sub Mo3d /) have been determined for a series of Al/sub 2/O/sub 3/ supported molybdenum oxides, characterized by a roughly constant Mo coverage and surface areas (/b S//sub BET/) ranging from 10 to 300 m

The position of the N1s level of aniline adsorbed on HY zeolite undergoes a shift of approximately-2 eV when the calcination temperature exceeds 400°C which is the dehydroxylation temperature for the zeolite. The ESCA line position seems to depend o
