Thermodynamic investigation of small homonuclear and heteronuclear molecules containing silicon and germanium
(1983)
The equilibrium involving gaseous species above the condensed systems Y/Ge, Y/Si, Sc/Ge, Sc/Si, Pd/Ge and Ni/Ge have been experimentally investigated at elevated temperatures by means of the high temperature mass spectrometric ...
Study of electron transfer processes involving lithium dialkylamides
(1984)
In this study the potential of a class of lithium dialkyamides to serve as mechanistic probes was investigated. Lithium N-butyl-4-pentenylamide 31 in THF rearranged smoothly to give a mixture (after protonation) which ...
Use of laser-excited atomic fluorescence spectroscopy for characterization of an argon inductively coupled plasma
(1985)
Laser-excited atomic fluorescence spectroscopy (LEAFS) is investigated and employed as a diagnostic technique for study of the argon inductively coupled plasma (ICP). Computer simulations are used to describe the behavior ...
Radiotracer mechanistic studies of heterogeneous adsorption and catalytic reactions
(1984)
Both the hydrogen adsorption and the catalytic reactions over Palladium have been studied with tritium as a radiotracer. The work is divided into two major portions: (i) The interactions of hydrogen with Pd black as well ...
Preparation and structural characterization of Re[subscript]2[superscript]n+ compounds containing sulfato, amidino, phosphine and methyl ligands
(1976)
Four new complexes containing the quadruply bonded Re₂ (superscript n+) unit have been synthesized and the structure of each has been determined by X-ray crystallographic methods. The first compound, Na₂Re₂(SO)₄)₄, was ...
Hydrocarbons via catalytic hydrogen treatment of a wood pyrolytic oil
(1981)
Pyrolysis exhibits promise as a process for the conversion of biomass residues into chemical and fuel feedstocks. The oil product derived from this process, namely pyrolytic oil, is a complex mixture of many components ...
Electrocatalysis of oxygen evolution of perovskite-type oxides
(1983)
A systematic investigation was made to correlate the electrocatalytic properties of perovskites, ABO(,3) (A is a lanthanide, B is a first row transition metal), for oxygen evolution with their electronic structures. The ...
Adsorptivities of azaarenes on Florisil
(1983)
Adsorptivities of azaarenes on Florisil were investigated; the study included the use of Florisil: (1) to analyze azaarenes in ambient air; (2) to evaluate substituent effects of various azaarenes on retention factors; and ...
The use of L-serine in the construction of carboalkoxy-substituted delta²-oxazoline, oxazole, delta²-thiazoline, and thiazole heterocyclic ring systems
(1983)
An (alpha)-amino acid was used in the preparation of non-peptide materials. The use of the (beta)-hydroxy-(alpha)-amino acid serine (14) was demonstrated to be effective in the construction of 2-substituted-4-carboxy-(DE ...
Investigation of the O₂̄[subscript n] + O₂ = O₂̄[subscript n]₊₂ equilibria from 77 ̊K to 373 ̊K
(1978)
The ion-molecule reactions O₂+O ⁻₂n = O ⁻₂n ₊₂, n=1-5, were studied in the pressure range of 1.5 to 12.0 torr and a temperature range of 77 to 373° K. The reactions occurred in a stream of partially ionized oxygen gas. ...
