Effect of tungsten carbide in carbon Pt catalyst support on electrochemical oxygen reduction in acid solution / Uticaj prisustva volfram-karbida u ugljeničnom nosaču Pt nanočestica na elektrohemijsku redukciju kiseonika u kiselom rastvoru
(Association of Chemical Engineers of Serbia, 2013)
Tungsten carbide was synthesized by calcination of carbon cryogel with embedded tungsten in a form of metatungstate. This material was used as a support for Pt nanoparticles. XRD pattern of W-C support indicated the presence ...
Electrocatalytic properties of Pt-Bi electrodes towards the electro-oxidation of formic acid / Elektrokatalitička svojstva Pt-Bi elektroda u oksidaciji mravlje kiseline
(Serbian Chemical Society, 2013)
Formic acid oxidation was studied on two Pt-Bi catalysts, i.e., Pt2Bi and polycrystalline Pt modified by irreversible adsorbed Bi (Pt/Biirr) in order to establish the difference between the effects of Biirr and Bi in the ...
Partial characterization of levan from Brachybacterium sp. CH-KOV3
(Belgrade : Institute of Technical Sciences of SASA, 2013)
The aim of this work was to investigate structure of exopolysaccharide produced by Brachybacterium sp. CH-KOV3 by planar chromatography, elemental analysis, FTIR, NMR and conduct basic rheological characterization. It has ...
A long way from the bifidogenic effect to antioxidative and pharmacologic properties of breast milk and infant formulas
(Beograd: Udruženje mikrobioologa Srbije, 2013)
Our examination of infant formulas bifidogenic effect-development stimulation of bifidogenic bacteria-probiotics in the intestinal tract by the effect of food ingredients which are bifidogenic factors-prebiotics for these ...
Fruktan iz Brachybacterium sp. CH-KOV3 - izolovanje, prečišćavanjene i delimična karakterizacija / Fructan from Brachybacterium sp. CH-KOV3 – isolation, purification and partial characterization
(Belgrade : Serbian Chemical Society, 2013)
Mikrobne polisaharide karakteriše velika strukturna raznolikost što omogućava veliki broj potencijalnih primena. Ekonomski značaj ovih polisaharida se ogleda u činjenici da su neki od ovih polimera danas široko zastupljeni ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO center dot ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Effect of four lichen acids isolated from Hypogymnia physodes on viability of rat thymocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Four lichen acids, physodalic acid (F1), physodic acid (F2), 3-hydroxyphysodic acid (F3), and isophysodic acid (F4), were isolated from Hypogymnia physodes methanol extract using preparative reversed-phase high performance ...
N-{[2-(4-Phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides with Dopamine D-2 and 5-Hydroxytryptamine 5HT(1A) Activity: Synthesis, Testing, and Molecular Modeling
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
The ratio of affinities toward the dopamine D-2 and the 5-hydroxytryptamine 5-HT1A receptors is one of the important parameters that determine the efficiency of antipsychotic drugs. Here, we present the synthesis of ortho-, ...
