Lanthanum-molybdenum coating for hydrogen evolution on titanium
(Switzerland : Springer Nature, 1984)
There is practical interest in the use of titanium as a cathode material in brine electrolysis processes. The overvoltage of hydrogen evolution on titanium is, however, very high and, at the same time, hydrogen penetrates ...
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 ...
Transformation of steroidal 5α,8α-peroxides to the 14-membered ring containing 5,10;8,9-diseco-steroid derivatives
(Elsevier, 1985)
Thermal decomposition of steroidal 5α,8α-peroxides (such as 1) resulted in bisfragmentation of the C(5)-C(10) and C(8)-C(9) bonds, and elimination of acetic acid, to produce a new type of bicyclic compounds, namely ...
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 ...
Structural effects in electrocatalysis: Oxidation of ethylene glycol on single crystal gold electrodes in alkaline solutions
(Elsevier, 1986)
Ethylene glycol is a potential fuel of practical interest whose electrooxidation has not been studied in detail. This is a complex reaction whose mechanism is far from being understood. It is quite clear, however, that ...
The application of Ramo's theorem to the impulse response calculation of a reach-through avalanche photodiode
(Elsevier, 1984)
A method for calculation the impulse response of a depletion layer of a semiconductor device based on Ramo's theorem is described. Using this method the impulse response of a reach-through avalanche photodiode is derived.
Some Observations Concerning 1H‐NMR. Spectra of 5‐hydroxy‐ and 5‐acetoxy‐steroid compounds
(Wiley-Blackwell, 1981)
It was found that analysis of the 1H‐NMR. signals (at 360 (preferably) and/or 100 MHz) of the protons at C (4) and of the equatorial α‐proton at C (6), particularly when these are located in the 2–3 ppm region and therefore ...
Electron transit time through depletion layer of GaInAs pn junction
(Institution of Engineering and Technology (IET), 1989)
Using an empirical formula for the electron velocity, the transist time through a Gao. 47Ino. 53As pn junction as a function of the applied voltage and other parameters is calculated. It is shown that a minimum transit ...
Identification of intermetallic compounds in electrodeposited copper-cadmium alloys by electrochemical techniques
(Elsevier, 1989)
Anodic sweep voltammetry was used to identify different intermetallic compounds and assess their amount in copper-cadmium alloys. Four compounds are found in thin (1–8 μm) electroplated alloy films: CuCd3, Cu5Cd8, Cu4Cd3 ...
Composition and thickness control of CdxHg1-xTe layers grown by open tube isothermal vapour phase epitaxy
(Elsevier, 1987)
Lowered Hg pressure due to the Hg loss out of the growth chamber strongly influences the properties of CdxHg1-xTe layers grown by open tube isothermal vapour phase epitaxy (ISO VPE). Conventional LPE slider systems are ...
