Intramolecular Cyclization of Some Unsaturated Alcohols by Means of Thallium Triacetate
(Weinheim : Wiley-VCH Verlag GmbH & Co., 1992)
Reactions of some primary and secondary Δ4‐, Δ5‐ and Δ6‐alkenols with thallium triacetate (TTA) in benzene, acetic acid and chloroform as solvent have been investigated. When terminally unsubstituted Δ4‐alkenols, such as ...
The roles of the ruthenium concentration profile, the stabilizing component and the substrate on the stability of oxide coatings
(Elsevier, 1992)
Electrocatalytic oxide coatings with variable concentration profiles of RuO2 as the active component were obtained through a combination of separately applied layers of RuO2, TiO2, IrO2, RuO2 + TiO2 and RuO2 + IrO2 on ...
Selenium content and distribution in rat tissues irradiated with gamma rays
(Heidelberg : Springer, 1992)
The effects of supplementation with selenous yeast and ionizing radiation on selenium (Se) content and distribution were evaluated in rat tissues (liver, kidney, spleen, heart, muscle, blood, front brain, hind brain, ...
Regioselectivity in Cyclofunctionalization of Olefinic Alcohols with Benzeneselenenyl Halides at Different Temperatures
(Wiley, 1992)
The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (−78°C, 0°C and room temperature) is investigated. It has been ...
Evaluation of the effects of native minerals on the organic matter of Aleksinac oil shale based on the composition of free and bound bitumens
(Organic Geochemistry, 1992)
In order to evaluate the adsorption and catalytic effects of indigenous carbonates and silicates on the organic matter of Aleksinac oil shale, the free and the bound bitumens were isolated and analyzed by organic geochemical ...
Fulvic acid characterization in an alluvial sediment sequence: differences between clay and sand environments
(Elsevier, 1992)
Fulvic acids (FAs) from the whole Quaternary sequence (to a depth of 26 m) of the alluvial sediment of the Sava river (taken from a site in Novi Beograd, Belgrade, Yugoslavia) were investigated with the aim of examining ...
Properties of activated alumina obtained by flash calcination of gibbsite
(Elsevier, 1992)
On exposing gibbsite, with granulation below 10 μm to flash calcination of 0.5 s in the regime of pneumatic transport and at temperatures above 883 K, a microcrystalline material with a high degree of amorphization was ...
Oxygen reduction on a modified ruthenium electrode
(Elsevier, 1992)
Oxygen reduction has been studied in alkaline solution on a ruthenium electrode modified by thallium and lead adsorbates. A partially oxidized ruthenium electrode is inactive for oxygen reduction. Thallium and lead adsorbates ...
Oscillatory phenomena in oxygen and hydrogen peroxide reduction on the Au(100) electrode surface in alkaline solutions
(Elsevier, 1992)
In this work we report preliminary data for oscillatory behavior found in oxygen and hydrogen peroxide reduction on a rotating gold electrode with (100) orientation in alkaline solutions.
Hydrogen adsorption on single-crystal platinum electrodes in alkaline solutions
(Elsevier, 1992)
Hydrogen adsorption on single-crystal platinum low-index and stepped surfaces was studied in 0.1 M and 0.01 M NaOH solutions. A strong dependence on the crystallographic orientation of the electrode surface was found. The ...
