Two‐dimensional NMR spectra of sesquiterpenes. I—NOESY study of caryophyllenes from Inula spiraeifolia
(John Wiley & Sons Ltd., 1987)
The application of two‐dimensional NOE NMR spectroscopy (NOESY) for the stereochemical assignment of isomeric 14‐acetoxy‐13‐hydroxy‐ and 13‐acetoxy‐14‐hydroxy‐5,6‐caryophyllen‐7‐ones, and their acetylation products, is ...
Determination of low levels of cyanide with a silver/silver sulphide wire electrode
(Elsevier, 1987)
A silver/silver sulphide electrode is prepred quickly by holding a cleaned silver wire in vapours from molten sulphur. In 1000-10 mg l-1 cyanide solutions, the electrode exhibits a linear E/log CCN function which becomes ...
Generalized model of the isothermal vapor phase epitaxy of (Hg,Cd)Te
(American Instituts of Physics, 1987)
A generalized model of the isothermal vapor phase epitaxy of (Hg,Cd)Te is presented, which for the first time enables us to predict the compositional profiles of the layers in dependence on growth parameters (temperature ...
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 ...
Determination of the kinetic parameters of the oxygen reduction reaction using the rotating ring-disk electrode. Part I. Theory
(Elsevier, 1987)
A general scheme of oxygen reduction is given and analysis of the disk-ring measurements is performed. Expressions for the diagnostic criteria for such a scheme have been derived and their implications are discussed. The ...
Determination of the kinetic parameters of the oxygen reduction reaction using the rotating ring-disk electrode. Part II. Applications
(Elsevier, 1987)
The criteria obtained for a new reaction scheme of O2 reduction have been applied to experimental data from several laboratories. The possibilities and merits of a new scheme have been analysed. Some results, not fully ...
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 ...
