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 ...
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 ...

Rad sadrži podatke o sastavu epifitskih silikatnih algi roda Navicula (sensu stricto i sensu lato) sa lokaliteta Suvi Do (Pešterska visoravan, Srbija). Uzorci su sakupljani u julu i septembru 2008. godine i u maju 2009. ...
Degradability of n-alkanes during ex situ natural bioremediation of soil contaminated by heavy residual fuel oil (mazut)
(Serbian Chemical Soc, Belgrade, 2013)
It is well known that during biodegradation of oil under natural geological conditions, or oil pollutants in the environment, degradation of hydrocarbons occurs according to a well-defined sequence. For example, the major ...
Surface and thermomechanical characterization of polyurethane networks based on poly(dimethylsiloxane) and hyperbranched polyester
(Budapest University of Technology, 2013)
Two series of polyurethane (PU) networks based on Boltorn (R) hyperbranched polyester (HBP) and hydroxyethoxy propyl terminated poly(dimethylsiloxane) (EO-PDMS) or hydroxy propyl terminated poly(dimethylsiloxane) (HP-PDMS), ...
Osetljivost na teške metale i rast na aromatičnim jedinjenjima bakterijskih sojeva izolovanih iz zemljišta kontaminiranog naftnim derivatima / Sensitivity to heavy metals and growth on aromatic compounds of bacterial strains isolated from soil contaminated with petroleum products
(Belgrade : Serbian Chemical Society, 2013)
Aromatični ugljovodonici dospevaju u životnu sredinu na različite načine, kao što su izlivanje nafte, sagorevanje fosilnih goriva, upotreba pesticida, curenje benzina. Pošto su toksični i potencijalno karcinogeni, razvijaju ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Internal-oxidation kinetics of ag-cd alloys
(Institute of Metals and Technology, 2013)
The oxidation kinetics of the Ag-Cd alloys with different Cd contents in mass fractions (9.5, 11, 12 and 16) % at (670, 750 and 795) degrees C during the production of Ag-CdO electrical-contact materials was investigated. ...
