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 ...
Synthesis, structure, and reactions of secosteroids containing a medium-sized ring. Part 17. Structure-reactivity relationship in the solvolysis of 5,10-secosteroidal 3-tosylates
(Royal Society of Chemistry, 1980)
Kinetic measurements of the solvolysis of (Z)-3α- and (Z)-3β-, and (E)-3α- and (E)-3β-tosyloxy-5,10-secocholest-1(10)-en-5-ones in buffered aqueous acetone (90 : 10 v/v) reveal that the (Z)-3α-, (E)-3α-, and (E)-3β-tosylates ...
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 ...
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 ...
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 ...
Characterization of electrochemically formed thin layers of binary alloys by linear sweep voltammetry
(Springer, 1988)
It has been demonstrated that linear sweep voltammetry can be used as anin situ technique for characterization of electrodeposited thin layers of binary alloys. The anodic dissolution characteristics of linear sweep ...
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 ...
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 ...
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.
