Cfd analysis and flow model reduction for surfactant production in helix reactor
(Savez hemijskih inženjera, Beograd, 2015)
Flow pattern analysis in a spiral Helix reactor is conducted, for the application in commercial surfactant production. Step change response curves (SCR) were obtained from numerical tracer experiments by three-dimensional ...
Mechanochemical synthesis of CaO·ZnO.K2CO3 catalyst: Characterization and activity for methanolysis of sunflower oil / Mehanohemijska sinteza CaO·ZnO.K2CO3, katalizatora - karakterizacija i aktivnost u metanolizi suncokretovog ulja
(Association of the Chemical Engineers of Serbia, 2015)
The goal of this study was to prepare a CaO·ZnO catalyst containing a small amount of K2CO3 and analyze its activity for biodiesel synthesis. The catalyst was prepared using the following procedure: CaO and ZnO (mole ratio ...
Influence of clay organic modifier on the morphology and performance of poly(epsilon-caprolactone)/clay nanocomposites
(Srpsko hemijsko društvo, Beograd, 2015)
Two series of poly(epsilon-caprolactone) poly(oxepan-2-one) nanocomposites with different organo-modified clays (1 to 8 wt. %) were prepared by the solution casting method. Organoclays with polar (Cloisite (R) C30B) and ...
Dissolution of copper mineral phases in biological fluids and the controlled release of copper ions from mineralized alginate hydrogels
(IOP Publishing Ltd, Bristol, 2015)
Here we investigate the dissolution behaviour of copper minerals contained within biocompatible alginate hydrogels. Copper has a number of biological effects and has most recently been evaluated as an alternative to expensive ...
Establishing Dependences between Different Lipophilic Parameters of New Potentially Biologically Active N-Substituted-2-Phenylacetamide Derivatives by Applying Multivariate Methods
(Oxford Univ Press Inc, Cary, 2015)
Lipophilicity, a very important parameter in the potential biological activities of molecules, was investigated for newly synthesized N-substituted-2-phenylacetamide derivatives. The determination was carried out in two ...
Selected trace element concentrations in ambient air and in horse chestnut leaves in Belgrade / Koncentracije odabranih elemenata u tragovima u vazduhu i u listovima divljeg kestena u Beogradu
(Association of the Chemical Engineers of Serbia, 2015)
In this study, airborne particulates (PM10) and leaves of horse chestnut were collected at selected urban sites in Belgrade, Serbia, in years 2006, 2009 and 2012. All samples were analysed for trace element concentrations ...
beta-Amylase production from packaging-industry wastewater using a novel strain Paenibacillus chitinolyticus CKS 1
(Royal Society of Chemistry, 2015)
Transport packaging factories generate a large amount of wastewater that contains residuals of starch glue. These residuals could be used as substrates for microorganism growth and enzyme production. In this study, ...
Keratin-polyethylene oxide bio-nanocomposites reinforced with ultrasonically functionalized graphene
(Royal Society of Chemistry, 2015)
Polyethylene oxide (PEO) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene in PEO aqueous solution. The feasible sonication protocol of PEO degradation and graphene functionalization enabled ...
The antimicrobial efficiency of silver activated sorbents
(Elsevier Science Bv, Amsterdam, 2015)
This study is focused on the surface modifications of the materials that are used for antimicrobial water treatment. Sorbents of different origin were activated by Ag+-ions. The selection of the most appropriate materials ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, Amsterdam, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
