New values of the polarity factor
(Serbian Chemical Society, 2000)
New values of the polarity factor χ for 96 substances are proposed. Estimation procedure is tested on the values of this factor from the original work of Halm and Stiel.44.
Supercritical CO2 extract and essential oil of bay (Laurus nobilis L.): Chemical composition and antibacterial activity / Natkritični ekstrakt i etarsko ulje lovora (Laurus nobilis L.) - hemijski sastav i antibakterijska aktivnost
(Srpsko hemijsko društvo, Beograd, 2010)
The present study deals with the supercritical carbon dioxide (SC-CO2) extraction and hydrodistillation (HD) of dried bay leaves (Laurus nobilis L.). The chemical composition and antibacterial activity of the SC-CO2 extract ...
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 ...
Randomly oriented twin domains in electrodeposited silver dendrites
(Serbian Chemical Society, 2015)
Silver dendrites were prepared by electrochemical deposition. The structures of the Ag dendrites, the type of twins and their distribution were investigated by scanning electron microscopy (SEM), Z-contrast high angle ...
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 ...
Thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n)
(Elsevier Science Bv, Amsterdam, 2011)
Multi-step thermal degradation of coordination polymer [Cd(N-Boc-gly)(2)(H2O)(2)](n) in non-isothermal conditions was studied. The kinetic parameters were determined from the thermal decomposition data using the isoconversion ...
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 ...
