Activation of aluminium in chloride containing solutions
(Elsevier, 1988)
Galvanostatic transients were recorded for anodic dissolution of high purity aluminium in neutral chloride solutions. All transients, except at very low current densities (below 50 μA cm-2), are characterized by an overshoot ...
Multistage alkaline permanganate degradation of a type-III kerogen
(Elsevier, 1985)
In order to obtain evidence on the relationship between kerogen structural types and the quantity and nature of their oxidation products, the products of a multistage (13 step) alkaline permanganate degradation of type-III ...
Deuterium‐induced 13C nuclear magnetic resonance isotope shifts and 13C-2H couplings for signal assignments and determination of deuteration site in cyclooctanone
(Wiley, 1981)
Unambiguous signal assignments in the 13C spectra of monodeuterated cyclooctanones derived from the lead tetraacetate or silver oxide/bromine oxidations of the corresponding 1‐monodeutero‐alcohols have been obtained from ...
Circular dichroism of some cyclopropane ring containing 1,3-cyclo-5,10-seco-steroidal ketones
(Elsevier, 1982)
Circular dichroism of the rearranged keto steroids 3 and 4, containing a condensed three and nine-membered ring system, shows that the conformation of the nine-membered ring is the same in solution as in the crystal; ...
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 ...
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 ...
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 ...
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.
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 ...
