The polarographic and chronopotentiometric investigation of the copper(II)-ethylenedithioldiacetic acid system
(Elsevier, 1975)
The electrode process of the Cu(II)-ethylenedithioldiacetic acid chelatereduction occurs in two one-electron reduction steps. The reversibility of the first polarographic wave was confirmed by microcoulometry at constant ...
Platinum-iridium catalyzed titanium anode. I. Properties and use in chlorate electrolysis
(Springer Science and Business Media LLC, 1975)
The use of dimensionally stable titanium anodes activated with Pt, Ir or ruthenium oxide for electrolytic chlorate production has been investigated. Simultaneous measurements were made of the amount of noble metal at the ...
Investigations of the Arc Burning in the Water Vapour Atmosphere
(Wiley, 1975)
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 ...
Carbon air electrode with regenerative short time overload capacity. II. Effects of duroquinone and 2-amino-1.4 naphthoquinone
(Switzerland : Springer Nature, 1975)
The short time overload capacity of the carbon-air electrode in a strongly alkaline electrolyte can be increased by addition of organic redox substances such as duroquinone (DQ) or 2-amino-1.4-naphthoquinone (ANQ). DQ, ...
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 ...
Catalytic effects of monolayers of metals deposited at underpotentials: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was recently shown that the monolayers of some metals deposited at underpotentials
on gold can substantially increase the rates of some redox reactions 1 , and the
rate of oxygen reduction:. This note reports the ...
The Electric Conductivity of Molten HgI2-HgBr2 and HgI2-SbI3 Binary Mixtures
(De Gruyter, 1975)
The specific electric conductivity of molten HgI2-HgBr2 and HgI2-SbI3 binary mixtures was measured as a function of composition and temperature in the ranges 220 — 540 °C and 180 to 540 °C, respectively. In the HgI2-HgBr2 ...
Electrocatalysis by foreign metal monolayers: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was demonstrated that some foreign metal monolayers formed by underpotential deposition have pronounced catalytic effects on the oxidation of formic acid on platinum. The explanation of these effects was sought within ...
Quercetagetin 6,7,3',4'-tetramethyl ether: a new flavonol from Artemisia annua
(Elsevier, 1975)
Plant: Artemisia annua L. Source: South of Belgrade. A CHCl, extract of the whole plant yielded after chromatography a new polar flavonol, yellow crystals, mp 171-172 degrees, M+ m/e 374, C19H18O8. characterized by UV/VIS, ...
Static characteristics of the metal-insulator-semiconductor- insulator-metal (MISIM) structure—II. Low frequency capacitance
(Elsevier, 1975)
It is shown that the reciprocal value of low frequency capacitance of a MISIM structure can be represented by a sum of reciprocal values of insulator layer and surface space charge capacitances and an “interaction” term ...
