Free-radical oxidative transformations of androst-4-ene-3β,9α,17β-triol 3,17-diacetate
(Tetrahedron, 1988)
The oxidation of androst-4-ene-3β,9α,17β-triol 3,17-diacetate (2) with lead tetraacetate resulted mainly In β-fragmentation of the C(9)-C(10) bond to give a mixture of 10α- and 10β-acetoxy-Δ4-unsaturated 9,10-seco-steroidal ...
Synthesis, structure, and reactions of secosteroids containing a medium-sized ring. Part 17. Structure-reactivity relationship in the solvolysis of 5,10-secosteroidal 3-tosylates
(Royal Society of Chemistry, 1980)
Kinetic measurements of the solvolysis of (Z)-3α- and (Z)-3β-, and (E)-3α- and (E)-3β-tosyloxy-5,10-secocholest-1(10)-en-5-ones in buffered aqueous acetone (90 : 10 v/v) reveal that the (Z)-3α-, (E)-3α-, and (E)-3β-tosylates ...
Structural effects in electrocatalysis. Oxygen reduction on the Au (100) single crystal electrode
(Elsevier, 1984)
The kinetics of O2 reduction on the Au (100) single crystal electrode have been examined in alkaline electrolytes using the rotating dise method. A comparison has been made with the Au (110) and Au (111) surfaces. The ...
Two-dimensional electrocrystallization of thallium oxide on the single crystal gold surfaces
(Elsevier, 1984)
The electrocrystallization of thin anodic films on metal electrodes continues
provoke interest since the original work of Bewick et al. [1]. These
studies have been focused on the film formation on mercury [1--3] ...

Photoelectrochemical microscopy of oxide films on metals: Ti/TiO2 interface
(Elsevier, 1988)
Thin electrochemically grown oxide films on polycrystalline titanium substrates were examined by photoelectrochemical and electron diffraction techniques. Photoelectrochemical microscopy, based on illumination by a focused ...
The effect of anions on the electrochemical behaviour of aluminium
(Elsevier, 1983)
Aluminum has been known to exhibit widely different electrochemical properties in different aqueous electrolytes. Thus, OH- ions in strongly alkaline solutions reveal its strong affinity to water by dissolving its protective ...
Fundamental aspects of plating technology I: The determination of the optimum deposition current density
(Elsevier, 1983)
It is shown that the optimum plating overpotential or the optimum current density is determined by the upper limit of validity of the Tafel relationship for the deposition process.
Structural effects in electrocatalysis: oxidation of formic acid and hydrogen adsorption on platinum single-crystal stepped surfaces
(Elsevier, 1986)
The oxidation of formic acid and hydrogen adsorption have been measured on platinum single-crystal stepped surfaces with five orientations. A pronounced structural sensitivity of both reactions has been found. They show a ...
Carbon monoxide oxidation on mixed spinels CuxCo3-xO4 (0 ≫ × ≫ 1) in the presence of sulphur compounds
(Elsevier, 1985)
The influence of the copper content in CuxCo3-xO4 (0 ≫ × ≫ 1) mixed oxides on carbon monoxide oxidation in the presence of SO2 was investigated. The average oxidation rate was found to increase very slowly with increasing ...
