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 ...
Treatment of electrostatic effects within the molecular mechanics Method. 2
(American Chemical Society, 1983)
The previously developed general method, which includes induction by dipoles in polarizable bonds and the solvation of molecular dipoles and quadrupoles, was used to calculate molecular dipole moments and to predict ...
Multistage alkaline permanganate degradation of a type II kerogen
(Elsevier, 1984)
The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, ...
Mass-spectrometric analysis of the products formed in a D.C. Arc Plasma / Massenspektrometrische Analyse der im Gleichstrombogen-Plasma gebildeten Produkte
(Springer Nature, 1980)
The carbon content was determined in the plasma of horizontal electric arc discharging between carbon electrodes in a) a graphite tube and b) a ceramic tube, in the presence of an inhomogeneous magnetic field. After 20 s ...
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 ...
Oxygen reduction on a ruthenium electrode in alkaline electrolytes
(Elsevier, 1986)
The kinetics of oxygen reduction have been studied on a ruthenium electrode in alkaline solutions using the rotating disc and rotating disc-ring methods. The reaction kinetics and mechanism were found to depend on the ...
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 ...
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 ...
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 ...
