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 ...
Synergistic electrocatalytic effect of Pd and Rh nanoislands co-deposited on Au(poly) on HER in alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
Hydrogen evolution reaction (HER) was explored on tri-metallic Rh"Pd/Au(poly) and bimetallic Pd/Au(poly) and Rh/Au(poly) electrodes in alkaline solution. Electrodes were prepared by the spontaneous deposition of either Pd ...
Catalytic activities of Pt thin films electrodeposited onto Bi coated glassy carbon substrate toward formic acid electrooxidation
(Elsevier, 2014)
Formic acid oxidation was studied on platinum-coated bismuth deposits on glassy carbon substrate. The catalyst was prepared by a two-step process using chronocoulometry, i.e. controlled amount of Bi was electrodeposited ...
Bioactive pullulan based edible films with medicinal herbal extracts
(Belgrade : Society of Physical Chemists of Serbia, 2018)
In this work, pullulan based films with water extracts of medicinal herbs thyme and sage, were prepared. The resulting films were characterized by FT-IR spectroscopy and their antioxidant and antimicrobial activities were ...
New views on strategic management / Novi pogledi na strategijski menadžment
(University of Novi Sad, Technical faculty Mihajlo Pupin, Zrenjanin, 2017)
Globalisation is the only economic way for national economies all around the world. The globalisation process is marked by the following characteristics: uneven industrial development, intensive application of information ...
Theoretical study of the molecular properties of dimethylanthracenes as properties for the prediction of their biodegradation and mutagenicity
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
There is little information available on methyl derivatives of anthracene and their interaction with the enzymes of bacterial consortia that could be found in petroleum sludge. In this study a theoretical investigation of ...
Phytoextraction of metals by Erigeron canadensis L. from fly ash landfill of power plant "Kolubara"
(Springer Heidelberg, Heidelberg, 2015)
The objectives of this study were to determine the concentrations of Pb, Cd, As, Cr, Cu, Co, Ni, Zn, Ba, Fe, Al and Ag in Erigeron canadensis L. growing on fly ash landfill of power plant "Kolubara", Serbia. The content ...
Cell wall invertase immobilisation within gelatin gel
(Elsevier Sci Ltd, Oxford, 2011)
Yeast cell wall invertase (CWI) was immobilised within 10% gelatin hydrogel. The result of entrapment was the complete immobilisation of all the added CWI. The activity of immobilised biocatalyst was 93 +/- 3 U/g, with ...
Identification of NQO1 and ferrochelatase as interaction partners for neuroprotective N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides
(Wiley, Hoboken, 2018)
Affinity chromatography was used to identify potential cellular targets that are responsible for neuroprotective activity of N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides. Active and inactive representatives ...
Characterization of carbon fibrous materials obtained from tree wastes
(Serbian Chemical Society, Belgrade, 2010)
Carbon fibres can be obtained in rather wide variety of structures, compositions and properties, depending on the nature of the organic precursor and conditions of the process applied in their preparation. In order to get ...
