Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
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 ...
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 ...
Determination of the kinetic parameters of the oxygen reduction reaction using the rotating ring-disk electrode. Part I. Theory
(Elsevier, 1987)
A general scheme of oxygen reduction is given and analysis of the disk-ring measurements is performed. Expressions for the diagnostic criteria for such a scheme have been derived and their implications are discussed. The ...
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 ...
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 ...
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 ...
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; ...
Transition metal catalysts for porous carbon air-electrodes in neutral chloride electrolytes
(Springer Nature, 1983)
Porous carbon air-electrodes activated by CoPC, FePHP, PdPC, PtPC and metal-free PC were studied in 2 mol dm-3 NaCl electrolyte. The activity of heat-treated carbon activated by CoPC was compared to carbon activated by in ...
Rotating disk electrode: A re-examination of some kinetic criteria with a special reference to oxygen reduction
(Elsevier, 1987)
Some of the well-known criteria for analysing rotating disk measurements have been examined. It has been shown that for reactions with complex mechanisms the number of electrons exchanged per reactant is a function of the ...
