Regulation of amino acid transport system L by amino acid availability in CHO-K1 cells. A special role for leucine
(Elsevier, 1985-10-10)
Starvation of CHO-K1 cells for leucine leads to a 3-4-fold increase in transport system L activity, without modification of transport through systems A and ASC. The concentration of leucine must be below 10 [mu]M before ...
Electron density measurements of argon surface-wave discharges
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-09)
The electron density of microwave-generated surface-wave discharges in argon have been measured using Stark broadening and calculated from the measured wavelengths of the standing surface wave. Results obtained from these ...
The molecular and crystal structure of pentacarbonyl(phosphabenzene)molybdenum(0)
(Elsevier, 1985-03-05)
Pentacarbonyl(phosphabenzene)molybdenum(0) crystallizes in the Pbam space group with Z = 8, a 15.880(4), b 20.162(4) and c 7.971(3) A. The crystal structure was determined and refined from 1404 independent reflections to ...
Molybdena on titania : I. Preparation and characterization by Raman and Fourier Transform Infrared spectroscopy
(Elsevier, 1985-04)
Titania-supported molybdenum and cobalt-molybdenum catalysts were prepared by the dry impregnation and equilibrium adsorption techniques. Raman and Fourier Transform Infrared spectroscopy were used to follow the changes ...
Influence of chlorine on the surface area and morphology of TiO2
(Elsevier, 1985)
Changes in BET surface area and morphology of TiO2 (anatase) were studied as a function of temperature and level of chlorine contamination. The obj
CO hydrogenation catalyzed by alumina-supported osmium: Particle size effects
(Elsevier, 1985-10)
Alumina-supported catalysts were prepared by conventional aqueous impregnation with [H2OsCl6] and by reaction of organoosmium clusters {[Os3(CO)12], [H4Os4(CO)12], and [Os6(CO)18]} with the support. The catalysts were ...
Metal dispersion of bimetallic catalysts via stepwise chemisorption and surface titration : I. Ru---Au/SiO2
(Elsevier, 1985-09)
A stepwise chemisorption and titration procedure involving H2 and O2 as adsorbates is used to measure the dispersion of the individual metal components in bimetallic Ru---Au/SiO2 catalysts. The experimental approach is ...
