Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Microstructure evolution of a modified AA5083 aluminum alloy during a multistage homogenization treatment
(Elsevier Science Inc, New York, 2012)
The microstructure evolution of the industrially cast AA5083 modified aluminum alloy during the multistage homogenization treatment was investigated by means of optical, SEM and TEM imaging and microanalysis techniques. ...
Decolorization of textile dye CI Basic Yellow 28 with electrochemically generated active chlorine
(Elsevier Science Sa, Lausanne, 2012)
Reaction of the indirect electrochemical decolorization of cationic textile dye CI Basic Yellow 28 with electrochemically generated "active chlorine" has been studied, using UV-Vis spectrophotometry, ion chromatography, ...
Novel kinetic model of the removal of divalent heavy metal ions from aqueous solutions by natural clinoptilolite
(Elsevier, Amsterdam, 2012)
Removal of heavy metal ions from aqueous solutions using zeolites is widely described by pseudo-second order kinetics although this model may not be valid under all conditions. In this work, we have extended approaches ...
Targeting and design of industrial zone waste heat reuse for combined heat and power generation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The basic materials industry contributes significantly to global energy demand. The efficient utilization of energy in these industries is essential to sustainable development. In numerous emerging countries, such industrial ...
Mechanism and dynamics of shrinking island grains in mazed bicrystal thin films of Au
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work investigates the mechanism and dynamics of grain boundary migration driven by capillary forces via in situ electron microscopy, complemented by molecular-dynamics simulations. Using thin films of Au with the mazed ...
Aspects of energy reduction by autogenous copper production in the copper smelting plant Bor
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work presents a comparative analysis of the energy consumption during copper production by the "standard" procedure (roasting in a fluo-solid reactor and smelting in a reverberatory furnace) in the Smelting Plant in ...
Effect of different fermentation parameters on L-lactic acid production from liquid distillery stillage
(Elsevier Sci Ltd, Oxford, 2012)
Expansion of lactic acid applications, predominantly for the preparation of biodegradable polymers increased the research interest for new, economically favourable production processes. Liquid stillage from bioethanol ...
Synthesis of n-amyl isobutyrate catalyzed by Candida rugosa lipase immobilized into poly(N-isopropylacrylamide-co-itaconic acid) hydrogels
(Elsevier Science Sa, Lausanne, 2012)
A commercial Candida rugosa lipase was immobilized into poly(N-isopropylacrylamide-co-itaconic acid) hydrogel under different pH immobilization conditions, characterized and evaluated for both hydrolytic activity in an ...
How to improve the economy of bioethanol production in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Bioethanol accounts for the majority of biofuel use worldwide, either as a fuel or a gasoline enhancer. In Serbia, the industrial production of bioethanol still relies on conventional feedstocks containing starch and sugar ...
