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 ...
An apparatus for simultaneous determination of electrical conductivity and thermogravimetric curves of solid systems
(Springer, 1975)
A new apparatus for measurement of electrical conductivity during thermogravimetric analysis is described. Results of an investigation of the water-zeolite system in the interval -200° up to +450° prove the suitability of ...
The lead tetraacetate reaction of alcohols containing a small ring. Part II. Cyclobutane‐methanols and cyclopropane‐ethanols
(Wiley, 1976)
The leadtetraacetate and lead tetraacetate/metal chloride oxidations of cyclobutane‐methanol, cyclopropane‐ethanol and the corresponding α, α‐diniethyl alcohols have been investigated and compared with the oxidative reactions ...
1H n.m.r. spectra of some bicyclic compounds: I—relative configurations of the diastereomeric endo‐α‐methyl‐5‐norbornene‐2‐methanols, the corresponding saturated analogues, and their cyclization ether products
(Wiley, 1977)
The configurational and conformational relationship at C‐2 and C‐α in the two racemic diastereomeric endo‐α‐methyl‐5‐norbornene‐2‐methanols and the corresponding saturated endo‐α‐methyl‐2‐norbornanemethanols were determined ...
Carbon-air electrode with regenerative short time overload capacity: Part 1. Effect of manganese dioxide
(Springer Nature, 1973)
To increase the overload capacity of the carbon-air electrode in alkaline electrolyte, without seriously changing the electrode potential during short-time overload periods, small amounts of MnO2 were added to carbon and ...
Individual ionic activities and mass transfer in anodic chlorate formation
(Switzerland : Springer Nature, 1973)
The individual activity of hypochlorite ion in concentrated neutral salt (NaCl-NaClO3) solutions has been estimated kinetically by measurement of the Faradaic efficiency in a chlorate producing system comprised of a cell ...
Corrosion of Pure and Amalgamated Zinc in Concentrated Alkali Hydroxide Solutions
(IOP Publishing, 1974)
Corrosion of pure and amalgamated zinc in pure concentrated KOH solutions was investigated using two methods: (a) galvanostatic measurements of the kinetics of hydrogen evolution with electrodic assessment of corrosion ...
Rotating two-ring electrodes as a tool for electrochemical investigations of gas-evolving reactions
(Elsevier, 1972)
It is shown that two concentric ring electrodes located on a rotating disc surface can be used as an instrument for chemical and electrochemical analysis of gas-evolving reactions up to rates of gas evolution from the inner ...
Pulsating potential electrolysis in the deposition of copper
(Elsevier, 1973)
A very low impedance circuit was constructed in order to provide a pulsating cathodic potential for a copper electrode immersed in a copper sulphate solution of the type used in copper refining. The increase in surface ...
Criteria for the determination of the stereochemistry of steroidal indolizidines
(Elsevier, 1974)
E/F-Indolizidine steroids, which represent a structural unit of Solanum alkaloids, have been synthesized and used to evaluate criteria (IR—Bohlmann bands,1a-c —hydrogenbond,2a-e NMR,3a-c mass spectra,4 kinetic studies of ...
