Influence of ionic equilibrium in the CuSO(4)-H(2)SO(4)-H(2)O system on the formation of irregular electrodeposits of copper
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The relative concentration of hydrogen ion (H(+)) as a function of sulfuric acid (H(2)SO(4)) concentration (calculated using Pitzer's model) and the electrochemical processes by which irregular copper deposits are formed ...
Low concentration volatile organic pollutants removal in combined adsorber-desorber-catalytic reactor system / Integrisani sistem adsorber-desorber-katalitički reaktor za uklanjanje malih koncentracija organskih zagađujućih materija
(Association of Chemical Engineers of Serbia, 2008)
The removal of volatile organic compounds (VOCs) from numerous emission sources is of crucial importance due to more rigorous demands on air quality. Different technologies can be used to treat the VOCs from effluent gases: ...
Crosslinked polyurethanes based on hyperbranched polymers / Umreženi poliuretani na bazi hiperrazgranatih polimera
(Association of Chemical Engineers of Serbia, 2008)
In this paper, two samples of polyurethane (PU) crosslinked with hydroxy -functonal hyperbranched aliphatic polyester of the second pseudo generation were investigated. For the synthesis of these crosslinked PUs two different ...
Direct observation of confined acoustic phonons in the photoluminescence spectra of a single CdSe-CdS-ZnS core-shell-shell nanocrystal
(Amer Physical Soc, College Pk, 2008)
We report on the direct observation of confined acoustic phonons in the photoluminescence spectra of single CdSe-CdS-ZnS nanocrystals, whose ligands were exchanged to poly(ethylene oxide) (PEO) before they were embedded ...
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 ...
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 ...
