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. ...
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 ...
Substituent efects on the carbon-13 chemical shifts in α-phenylpyridylacrylic acids
(Elsevier Science Publishers B.V., 1992)
The 13C N.M.R. spectra of some substituted α-phenylpyridylacrylic acids, α-phenyl, α-(3-pyrydyl) and α-(3-pyrydyl-N-oxide) cinnamic acids were determined in deuterated dimethyl sulfoxide (d6-DMSO). It has been shown that ...
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.
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 ...
The initiation of dendritic growth of electrodeposited copper on a rotating disc electrode with changing copper concentration and diffusion layer thickness
(Elsevier, 1992)
It is shown that the critical overpotential of dendritic growth initiation increases with increasing copper concentration under identical hydrodynamic conditions, as well as with increasing rotation speed to the rde (rotating ...
Conformations in unsymmetrically N-n-propyl-N-substituted 2-phenylacetamides
(Elsevier Science Publishers B.V, 1992)
As a part of a study on the structural characteristics of some new various N-alkyl-N-substituted 2-phenylacetamides the infrared and 1 H N.M.R. spectra were obtained and interpreted. The synthesis of a various N-n-propyl-N-alkyl ...
Anodic stability and electrochromism of electrodeposited ruthenium-iridium coatings on titanium
(Elsevier, 1992)
The anodic behaviour of galvanically plated ruthenium-iridium coatings on titanium was investigated. The dependence of the Tafel slopes and the stability of the coatings for the oxygen evolution reaction in sulphuric acid ...
Coated-wire and composite ion-selective electrodes based on doped poly(pyrrole)
(Royal Society of Chemistry, 1992)
Chemically and electrochemically prepared doped poly(pyrrole) has been evaluated as a membrane component for ion-selective electrodes (ISEs). Two types of ISE were prepared: coated-wire electrodes (CWEs) and classical ISEs ...
