Optical and electrochemical study of cation adsorption on oxide layers on gold and platinum electrodes
(Elsevier, 1985)
It has been shown that the adsorption of Bi3+ and Tl+ cations occurs on oxide layers of Au and Pt electrodes in acid solutions. The initial stages of oxide formation and reduction are inhibited. The effect increases with ...
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 ...
The solvent effect on the conformational equilibrium of 1,3-dichloro-5-methylcylclohexane
(Elsevier, 1985)
The conformational equilibrium has been measured for r-1,c-3-dichloro-t-5-methylcyclohexane(2) in six solvents from the 500 MHz and 400 MHz 1H NMR spectra. The room-temperature and low-temperature C1H couplings are used ...
The Reductive Conversion of Some Cyclic and Acyclic vic-Epoxides to Alcohols by Means of Lithium Aluminium Hydride/Aluminium Trichloride
(Wiley, 1985)
Unsubstituted medium‐ring 1,2‐epoxycycloalkanes and certain vic‐epoxyalkanes are reduced to the corresponding alcohols very slowly when LiAlH4 alone is used as reducing agent. However, the combination of LiAlH4 and AlCl3, ...
The behaviour of mixed metal sulphide/silver suphide sensing materials in solutions of silver ions
(Analytica Chimica Acta, 1985)
Hydrophobized graphite electrodes activated with CuS/Ag2S can be used to measure silver ion activities as effectively as silver sulphide electrodes, whereas electrodes activatd with PbS/Ag2S or CdS/Ag2S are useless for ...
A novel pimara-8(9),15-diene from lycopus europaeus
(Pergamon Press, 1985)
Identification of a novel trioxygenated Δ8(9),15_ pimaric acid methyl ester from plant species Lycopus europaeus by means of two-dimensional 1H NMR spectroscopy (COSY and NOESY) is reported. © 1985.
Carbon monoxide oxidation on mixed spinels CuxCo3-xO4 (0 ≫ × ≫ 1) in the presence of sulphur compounds
(Elsevier, 1985)
The influence of the copper content in CuxCo3-xO4 (0 ≫ × ≫ 1) mixed oxides on carbon monoxide oxidation in the presence of SO2 was investigated. The average oxidation rate was found to increase very slowly with increasing ...
Solvent effect on conformational equilibria. Solvation energy as a function of solute position and orientation within a cavity in a dielectric medium
(Royal Society of Chemistry, 1985)
The reaction-field theory based on dipole and quadrupole interactions has been generalized, yielding an expression for the energy as a function of point dipole and quadrupole position and orientation within a spherical ...
Underpotential deposition of metals in the presence of surfactants: Deposition of thallium and lead on an Ag (100) electrode in the presence of sodium dodecyl sulphate
(Elsevier, 1985)
In this work sodium dodecyl sulphate (SDS) was used to modify the surface of an Ag (100) single crystal electrode. Both the underpotentlal deposition (UPD) and overpotential deposition (OPD) of thallium and lead were studied ...
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 ...
