Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O2 nanocatalyst / Elektrohemijska oksidacija metanola na katalizatoru Pt/(RuxSn1-x)O2
(Serbian Chemical Society, Belgrade, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O2 support and the Pt/(RuxSn1-x)O2 catalyst were characterized ...
Analysis of copper losses throughout weak acid effluent flows generated during off-gas treatment in the new copper smelter RTB Bor
(Association of Metallurgical Engineers of Serbia, 2013)
The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter ...
Comparative Study of Batch and Fluidized Bed Bioreactors for Lipase-Catalyzed Ethyl Cinnamate Synthesis
(Amer Chemical Soc, Washington, 2013)
Ethyl cinnamate, an ester known as flavor and fragrance compound, has been synthesized using two immobilized bioreactor systems, batch and fluidized bed bioreactors. The enzyme used for this synthesis is a commercial lipase ...
Contamination of cakes with toxigenic molds / Kontaminacija poslastičarskih proizvoda toksigenim plesnima
(Matica Srpska, 2013)
The total number of molds in cakes ranged up to 9.0 x 102 CFU/g. The highest number of molds was isolated on Dichloran 18% Glycerol Agar (DG18), and the lowest on Malt Yeast Extract 50% Glucose Agar (MY50G). Mycopopulation ...
Physical, chemical and structural effects as important factors for the determination of thermodynamic and transport properties and the modelling of non-electrolyte solutions / Fizički, hemijski i strukturni efekti kao važni faktori za određivanje i modelovanje termodinamičkih i transportnih svojstava neelektrolitnih rastvora
(Serbian Chemical Society, Belgrade, 2013)
In our previous review, an attempt was made to relate the volumetric effects involved in binary mixtures of normal and branched alcohols. The present paper summarizes some selected research activities related to complex ...
The adsorption of imidacloprid onto activated carbon obtained by carbonization of pine cones / Adsorpcija imidakloprida na aktivnom uglju dobijenom karbonizacijom borove šišarke
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
Pine cones of European Black pine are utilized as a precursor for obtaining powdered activated carbon. The concentrated phosphoric acid was used as an activating agent. A detailed study of the imidacloprid adsorption onto ...
Hemocompatibility, swelling and thermal properties of hydrogels based on 2-hydroxyethyl acrylate, itaconic acid and poly(ethylene glycol) dimethacrylate
(Springer, New York, 2013)
Two series of novel hydrogels, based on 2-hydroxyethyl acrylate (HEA), itaconic acid (IA), and two poly(ethylene glycol) dimethacrylates (PEGDMA), of different ethylene glycol chain lengths, were prepared by free radical ...
