Electrocatalysis on Surfaces Modified by Foreign Metal Adatoms
An approach to the problem of electrocatalysis, which consists of modification of electrode surfaces by foreign metal adatoms, is presented. The paper reviews the work done in the author's lab on the effects of foreign ...
A new type of d.c. arc as spectrochemical light source
(Elsevier BV, 1974)
A new type of d.c. arc light source for spectrochemical purposes has been developed. The horizontal arc burning in a graphite tube is placed in an inhomogeneous magnetic field. The limits of detection of In and Pb have ...
Acceleration of electrocatalytic reactions by pulsation of potential: Oxidation of formic acid on Pt and Pt/Pbads electrodes
(Pergamon Press, 1978)
Pulsating potential electrolysis has been applied to one typical electrocatalytic reaction ie, the oxidation of formic acid on platinum and platinum partially covered by lead adatoms electrodes. It has been found that much ...
Control of intramolecular γ-alkylation vs. α-alkylation of an αβ-unsaturated ketone: An unusual solvent effect
(Royal Society of Chemistry, 1979)
Most base-solvent combinations convert (2) into (3); γ-alkylation to yield (5) is effected by sodium hydroxide in dimethyl sulphoxide-water mixtures in which the water content is critical.
Electrocatalysis by foreign metal monolayers. Oxidation of formic acid on palladium
Catalytic effects of foreign metal monolayers deposited at underpotentials have been found for the oxidation of formic acid on palladium electrode. Palladium is known to form no poisoning species in oxidation of HCOOH. ...
Effect of codeposition of polymer on the morphology of electrodeposited copper
(Kluwer Academic Publishers, 1979)
Poly(4-vinyl pyridine-co-methyl methacrylate), which is soluble in water in its protonated form and insoluble as a neutral molecule, has been synthesized and introduced into an acid bath for copper deposition. Potential-sweep ...
A simple boundary condition at semiconductor-insulating substrate interface of a TFT
(Elsevier BV, 1977)
Using the Wexler, Green and Miles (WGM) procedure, a criterion is given for neglecting the electric field in insulating substrate of a Thin Film Transistor in presence of surface states. It is shown that this is fulfilled ...
The effect of the plasma composition on characteristics of the d.c. arc - V The influence of iodine vapour on the radial temperature distribution of the arc burning in the atmosphere of nitrogen and argon
(Elsevier BV, 1971)
Considering the solutions of the Elenbaas-Heller energy balance equation it is possible to indicate how the chemical reactions among the components of added substances influence the radial temperature distribution in the ...
The effect of the plasma composition on characteristics of the d.c. arc - I General discussion of the effect of the chemical reactions
(Elsevier BV, 1971)
The influence of chemical reactions among the components of the arc atmosphere on the radial temperature distribution is discussed. Their effect on other arc plasma characteristics and the spectrochemieal determination of ...
Investigations of the Arc Burning in the Water Vapour Atmosphere
The functions of thermal conductivity α(T) and electrical conductivity σ(T) for water vapour, within the temperature intervals 7700–8000 K and 2000–3500 K, were calculated. These calculations were performed by using the ...
