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 ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Synthesis of tetraalkylthiuram disulfides using different oxidants in recycling solvent mixture / Sinteza tetraalkiltiuram-disulfida primenom različitih oksidacionih sredstava u reciklovanoj smeši rastvarača
(Association of the Chemical Engineers of Serbia, 2012)

Isolation of Hemoglobin from Bovine Erythrocytes by Controlled Hemolysis in the Membrane Bioreactor
(Springer, New York, 2012)
In this work, we describe an optimized procedure based on gradual hemolysis for the isolation of hemoglobin derived from bovine slaughterhouse erythrocytes in a membrane bioreactor. The membrane bioreactor system that ...
A study of the photocatalytic degradation of the textile dye CI Basic Yellow 28 in water using a P160 TiO2-based catalyst / Proučavanje fotokatalitičke degradacije tekstilne boje CI Basic Yellow 28 u vodi koristeći P160 katalizator na bazi TiO2
(Serbian Chemical Society, Belgrade, 2012)
The photocatalytic degradation of the synthetic textile dye CI Basic Yellow 28 (BY28) in water, using a recently synthesized P160 TiO2-based catalyst, under Osram ultra-vitalux® lamp (300 W) light, was studied. The effects ...
Antioxidative capacity of fermented red bean and its protein hydrolysate fractions / Antioksidativni kapacitet fermentisanog crvenog pasulja i njegovih proteinskih hidrolizata
(Društvo za ishranu Srbije, Beograd, 2012)
In this study we investigated the antioxidant activity of native and fermented red bean, or their polyphenol and peptide fractions. It was found that the antioxidant activity determined by DPPH, FRAP and TBA, significant ...
Removal of Mg from spring water using natural clinoptilolite
(Mineralogical Soc, Twickenham, 2012)
Natural zeolitic tuff from Brus (Serbia) consisting mostly of clinoptilolite (about 90%) has been investigated for the reduction of the Mg concentration in spring water. The sorption capacity of the zeolite is relatively ...
Service life test of non-noble metal composite cathodes for hydrogen evolution in sodium hydroxide solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and ...
Influence of monomer and crosslinker molar ratio on the swelling behaviour of thermosensitive hydrogels / Uticaj molarnog odnosa monomera i umreživača na karakteristike bubrenja termoosetljivih hidrogelova
(Association of the Chemical Engineers of Serbia, 2012)
The synthesis of the poly(N-isopropylacrylamide-co-2-hydroxypropyl-methacrylate) hydrogel along with the analysis of the residual monomers content and influence of monomer and crosslinker molar ratios on the swelling ...
