Electrosorption of hydrogen and sulphuric acid anions on single-crystal platinum stepped surfaces. Part I. The [110] zone
(Elsevier, 1988)
The adsorption of hydrogen and sulphuric acid anions has been studied on single-crystal platinum stepped surfaces from the [110] zone. Both processes depend on the orientation of the electrode surface. The multiple states ...
Determination of the kinetic parameters of the oxygen reduction reaction using the rotating ring-disk electrode. Part II. Applications
(Elsevier, 1987)
The criteria obtained for a new reaction scheme of O2 reduction have been applied to experimental data from several laboratories. The possibilities and merits of a new scheme have been analysed. Some results, not fully ...
Synergetic electrocatalytic effect of d metals for the hydrogen evolution reaction on gold substrates
(Elsevier, 1984)
An electrocatalytic method developed previously for the depolarization of the hydrogen evolution reaction (HER) on graphite, iron, steel, nickel and titanium substrate surfaces was employed to improve the polarization ...
Mass spectrometric analysis of the carbon content in the plasma of a horizontal electric arc burning in a graphite tube / Massenspektrometrische Analyse des Kohlenstoffgehaltes im Plasma einer horizontalen Bogenentladung in einem Graphitrohr
(Springer Science and Business Media LLC, 1981)
The carbon content in the plasma of a horizontal electric arc in a graphite tube, burning in air, in the presence of an inhomogeneous magnetic field has been determined. The modifications with one and two rotating arc ...
Optical and electrochemical study of cation adsorption on oxide layers on gold and platinum electrodes
(Elsevier, 1985)
It has been shown that the adsorption of Bi3+ and Tl+ cations occurs on oxide layers of Au and Pt electrodes in acid solutions. The initial stages of oxide formation and reduction are inhibited. The effect increases with ...
The solvent effect on the conformational equilibrium of 1,3-dichloro-5-methylcylclohexane
(Elsevier, 1985)
The conformational equilibrium has been measured for r-1,c-3-dichloro-t-5-methylcyclohexane(2) in six solvents from the 500 MHz and 400 MHz 1H NMR spectra. The room-temperature and low-temperature C1H couplings are used ...
Circular dichroism of some cyclopropane ring containing 1,3-cyclo-5,10-seco-steroidal ketones
(Elsevier, 1982)
Circular dichroism of the rearranged keto steroids 3 and 4, containing a condensed three and nine-membered ring system, shows that the conformation of the nine-membered ring is the same in solution as in the crystal; ...
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 ...
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 ...
Structural effects in electrocatalysis: Oxygen reduction on the gold single crystal electrodes with (110) and (111) orientations
(Elsevier, 1984)
The kinetics of O2 reduction on the Au (110) and the Au (111) single crystal electrodes have been examined using the rotating disc method. The quality of the surfaces has been determined by Auger electron spectroscopy and ...
