Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
The representative particle of copper powder and branch of copper dendrites / Reprezentativna čestica bakarnog praha i grananje dendrita bakra
(Serbian Chemical Society, 2002)
Electrochemically deposited copper powders, which are formed of particles of different size and morphology, are characterized by some properties like specific surface and apparent density. Aprocedure of the determination ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
Colloid electrohydrodynamics
(Savez hemijskih inženjera, Beograd, 2009)
This brief extracted review presents the recent development in basic and applied science and engineering of finely dispersed particles and related systems in general, but more profound and in-depth treatise are related to ...
Ductile fracture prediction of steam pipeline steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Considering the conditions to which steels used for the manufacture of steam pipelines are exposed, the micromechanism of their destruction in exploitation is exclusively the ductile one. In order to make an estimation of ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
