Heat capacity, thermodynamic properties, and transitions of silver iodide
(Elsevier, 1989-06)
The heat capacity of silver iodide was measured using adiabatic calorimetric cryostats over the ranges 7 to 350 K and from 2 to 75 K. The ([beta] to [alpha])- and ([beta]/[gamma] to [alpha])-transitions and the heat ...
Barriers to US industrial biotechnology research consortia
(Elsevier, 1989-09)
In 1986-1987, the research directors of major and medium-sized US biotechnology companies agreed on the wisdom of developing cooperative research arrangements in protein engineering, bioprocess and large-scale animal cell ...
Standard molar Gibbs free energy of formation for Cu2O: high-resolution electrochemical measurements from 900 to 1300 K
(Elsevier, 1989-04)
Oxygen-concentration cells with zirconia solid electrolytes have been used to make equilibrium measurements of the standard molar Gibbs free energy of formation for copper(I) oxide, [Delta]fGmo(Cu2O), over the temperature ...
The benzene-SO2 and pyridine-SO2 complexes
(Elsevier, 1989-07-21)
The benzene-SO2 and pyridine-SO2 complexes have been observed for the first time using Fourier transform microwave spectroscopy. The complexes have different geometries. In benzene-SO2, the two planar species are stacked ...
Production of XeO * in a CW microwave discharge
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-12)
A low-power CW microwave discharge at 2.45 GHz was used to produce XeO * excimer molecules. It was found that a total gas pressure between 5 and 20 Torr, absorbed power of about 20–100 W, and an oxygen-to-xenon ratio of ...
Synthesis of the optically active [alpha]-nucleic acid base substituted propanoic acids
(Elsevier, 1989)
The (R)-2-(adenin-9-yl)propanoic acid was prepared from adenine and (S)-ethyl lactate by using the triphenyl phosphine-diethyl azodicarboxylate system. The (R)-2-(thymin-1-yl)-propanoic acid, (R)-2-(cytosin-1-yl)propanoic ...
Molecules with high rotational angular momentum: a generalized ab initio approach
(Elsevier, 1989-09)
An outline is given of a systematic and automated computational procedure based upon our successful ab initio approach to the theoretical study of centrifugal distortions of rotating molecules and their associated energy ...
Segregation measures for diffusion-controlled A+B reactions
(Elsevier, 1989-11-24)
New measures of segregation are defined and calculated for the A + B-->0 reaction on one-dimensional and fractal lattices (Sierpinski carpet and gasket). We differentiate between local and global segregation parameters. ...
Solid state synthesis and characterization of model hydrodesulfurization catalysts
(Elsevier, 1989-10)
Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of Co2xMo1-xS2 ...
Preparation and activity of solid-state hydrodesulfurization catalysts
