A new procedure for the treatment of an industrial waste containing flotation reagents / Novi postupak prerade industrijskog otpada koji sadrži flotoreagense na bazi ksantata
(Association of Chemical Engineers of Serbia, 2014)
Flotation reagents can be transformed to industrial waste if they are stored for a long period of time. Also, if synthesis or drying process is not performed under defined conditions in industrial plants, which produce ...
Study on the efficient removal of clopyralid from water using a resorcinol-formaldehyde carbon cryogel
(Srpsko hemijsko društvo, Beograd, 2014)
A resorcinol-formaldehyde carbon cryogel was prepared, characterized and used for the removal of the commonly used herbicide clopyralid from aqueous solutions under varying experimental conditions. The carbon exhibited a ...
The effect of the size and shape of alumina nanofillers on the mechanical behavior of PMMA matrix composites
(Srpsko hemijsko društvo, Beograd, 2014)
Composites with the addition of alumina nanofillers show improvement in mechanical properties.Poly(methyl methacrylate), PMMA, was used as a matrix and two different types of nanofillers having extremely different shapes ...
A comparative study of the removal of lead, cadmium and zinc ions from aqueous solutions by natural and Fe(III)-modified zeolite / Uporedna analiza uklanjanja jona olova, kadmijuma i cinka iz vodenih rastvora adsorpcijom na prirodnom i Fe(III)- modifikovanom zeolitu
(Association of the Chemical Engineers of Serbia, 2014)
The main purpose of this research was to explain the differences in the adsorption mechanisms and adsorption capacities of natural and Fe(III)-modified zeolite for Pb2+, Zn2+ and Cd2+. The adsorbents were characterized ...

(Institute of Metals and Technology, 2014)
The influence of mass fractions 1.5 % Nb and 1.5 % V, added singly and in combination, on the microstructural characteristics and properties relevant to the service performance of the hypoeutectic high-chromium white iron ...
Synthesis, characterization and crystal structure of Cu(II) complex with a diimine-dioxime ligand, [Cu-2(LH)(2)](ClO4)(2). Influence of the weak Cu center dot center dot center dot O(perchlorate) interaction on the structure of the Cu2N2O2 metallocycle
(Srpsko hemijsko društvo, Beograd, 2014)
The diimine dioxime ligand, 3,3'-(1,4-butanediyl-dinitrilo)bis-2-pentanone, 2,2'-dioxime (LH2), containing a N-4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane ...
Corrosion Evaluation of Zirconium Doped Oxide Coatings on Aluminum Formed by Plasma Electrolytic Oxidation
(Slovenian Chemical Society, 2014)
The plasma electrolytic oxidation (PEO) of aluminum in sodium tungstate (Na2WO4 center dot 2H(2)O) and Na2WO4 center dot 2H(2)O doped with Zr was analyzed in order to obtain oxide coatings with improved corrosion resistance. ...
A microwave approach to the synthesis of certain 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2014)
A study of the synthesis of 4-(substituted phenyl)-6-phenyl-3-cyano-2-pyridones from ethyl 2-cyano-3-(substituted phenyl) acrylates and acetophenone is presented. The 2-pyridones were obtained using conventional as well ...
Momentum, heat, and mass transfer analogy for vertical hydraulic transport of inert particles / Analogija prenosa količine kretanja, toplote i mase pri vertikalnom hidrauličkom transportu inertnih čestica
(Association of Chemical Engineers of Serbia, 2014)
Wall-to-bed momentum, heat and mass transfer in the vertical liquid-solids flow, as well as in the single phase flow, were studied. The aim of this investigation was to establish the analogy among those phenomena. Also, ...
