Degradative side reactions in the syntheses of exactly alternating silarylene-siloxane polymers
(Springer, 1992)
Four principal synthetic methods for preparation of exactly alternating silarylene-siloxane polymers: the chlorosilane, the acetoxysilane, the aminosilane and the ureidosilane polymerization reactions, were compared under ...
Oxygen reduction on Au (100) and vicinal Au (910) and Au (11, 1, 1) faces in alkaline solution. A rotating disc-ring study
(Elsevier, 1992)
The kinetics of oxygen reduction have been studied on Au (100) and vicinal Au (910) and Au (11, 1, 1) faces in 0.1 M NaOH by a rotating disc-ring method. A very high activity of these surfaces for O2 reduction was demonstrated. ...
Phase-structure analysis of brass by anodic linear-sweep voltammetry
(Springer, 1992)
Anodic linear-sweep voltammetry (ALSV) was applied to electrodeposited alloy layers and to metallurgically obtained Cu−Zn alloys of different composition and structure. Metallurgically obtained samples covered the range ...
Opening of the Macrocyclic Ring in 5,10:8,9‐Disecosteroids ( = Steroklastanes)
(Weinheim : Wiley-VCH Verlag GmbH & Co., 1992)
Catalytic hydrogenation of the Δ3‐unsaturated (9R,10 R)‐ and (9S,10 S)‐epoxyenol lactones 3a, b., and 4a, b., respectively, affords, in addition to the expected saturated epoxylactones 5a, b and 7a, b, also open‐chain ...
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 ...
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.
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 ...
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 ...
