Structural effects in electrocatalysis. Oxidation of D-glucose on single crystal platinum electrodes in alkaline solution
(Elsevier, 1991)
Electrochemical oxidation of D-glucose has been studied in 0.1 M NaOH on single crystal platinum electrodes with thirteen different orientations. The reaction rate depends strongly on the crystallographic orientation of ...
Effect of substituents on the 13 C chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, 1999)
13 C chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C 6 H 4 -X, X having a wide range of substituent effects, have been determined in CDCl 3 solution. Exceptionally ...
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.
Standard potential values of "cyanide-sensitive" silver iodide and silver sulphide ion-selective electrodes
(Analytica Chimica Acta, 1990)
It is shown that the equation for the potentials of semiconductive sulphide membranes given by Sato 25 years ago is valid also for the calculation of E0 values of "cyanide-sensitive" ion-selective electrodes. The only ...
Kinetic and mechanistic study of methanol oxidation on a Pt(110) surface in alkaline media
(Elsevier, 1998)
The comparative study of methanol oxidation on a Pt(110) surface was carried out in bicarbonate, carbonate and sodium hydroxide solutions. It was shown that OH- electrosorption precedes the oxide layer formation in sodium ...
Corrosion rates and negative difference effects for Al and some Al alloys
(Springer, 1999)
The rotating disc-ring technique with a Pt ring was used to quantitatively detect hydrogen evolved on an Al-disc electrode during spontaneous corrosion at open-circuit potential or during anodic polarization of an Al disc ...
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 ...
The role of surface defects in HOPG on the electrochemical and physical deposition of Ag / Uloga površinskih defekata na HOPG-u u elektrohemijskoj I fizičkoj depoziciji Ag
(Belgrade : Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
Isothermal vapour-phase epitaxy of mercury-cadmium telluride (Hg,Cd)Te
(Switzerland : Springer Nature, 1995)
Isothermal vapour-phase epitaxy (ISOVPE) was the earliest process to be developed for the fabrication of epitaxial mercury-cadmium telluride layers. Although the process was somewhat neglected in the previous period, mostly ...
