Electrocatalysis of oxygen on single crystal gold electrodes
(Elsevier, 1989)
Oxide formation and oxygen reduction on gold have been investigated with single crystal electrode surfaces of various orientations. Both reactions show sensitivity to the surface orientation, presence of steps, their density ...
Sesquiterpene lactones from Inula helenium
(Pergamon Press, 1989)
The isolation of 11(13)-dehydrocriolin [a germacranolide also known as 11(13)-dehydroivaxillin], 2α-hydroxyalantolactone, 4α,5α-epoxy-10α,14-H-inuviscolide (the major component) and carabrone from the aerial parts of Inula ...
Local film thickness and photoresponse of thin anodic TiO2 films on polycrystalline titanium
(Elsevier, 1989)
Auger depth profiling was used to determine the local film thickness of a thin anodic oxide grown on a polycrystalline Ti substrate. The oxide thickness was studied as a function of substrate crystallography and final ...
Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
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 ...
Quantum efficiency and responsivity of InSb photodiodes utilizing the Moss-Burstein effect
(Elsevier, 1989)
In this work a detailed analysis of the quantum efficiency of InSb n+-p photodetectors produced by liquid phase epitaxy is given, in the case when the n+ region is doped to such a level that the Moss-Burstein effect plays ...
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 ...
