Kinetic of corrosion reactions in acid and neutral solutions on electrochemically deposited Ni-W alloys / Kinetika korozionih reakcija u kiselim i neutralnim rastvorima na elektrohemijski taloženim legurama Ni-W
(Belgrade, Serbia : Engineering Society for Corrosion, 2006)
Ni-W alloys were electrochemically deposited from an ammonia-citrate electrolyte on rotating disc electrode with a gold disc, by direct and pulsating current. The corrosion potential and kinetics of cathodic and anodic ...
Elektrohemijska oksidacija metanola i mravlje kiseline na model i realnim katalizatorima / Electrochemical oxidation of methanol and formic acid on model and real catalysts
(Универзитет у Београду, Технолошко-металуршки факултет, 2006)
Prema svim dosadašnjim saznanjima o okisdaciji metanola za odigravanje ove reakcije neophodo je prisustvo OH čestica na površini elektrode. One su neophodne i za oksidaciju mravlje kiseline po jednom od dva paralelna ...

The formation of natural gas prices charged to very large industrial users in Serbia according to standards of the European union / Formiranje cena prirodnog gasa za velike industrijske potrošače u Srbiji prema standardima evropske unije
(Institut za istraživanja i projektovanja u privredi, Beograd, 2006)
Natural gas is a primary energy resource with the indicated highest annual growth of global demand and consumption in all recent forecasts. The chemical industry is a leading non-seasonal consumer of natural gas, mainly ...
Phytochemical investigation of Anthemis cotula / Фитохемијско испитивање биљне врсте Anthemis cotula
(Serbian Chemical Society, 2006)
The investigation of roots of Anthemis cotula (Asteraceae) from east Serbia revealed, in addition to polyacetylenes previously isolated from the same species, three prenylated 4-hydroxyacetophenones, detected for the first ...
Synthesis of porous poly(methylmetacrylate) / Sinteza poroznog poli(metilmetakrilata)
(Društvo inženjera plastičara i gumara, Beograd, 2006)
A synthesis of porous poly(methylmetacrylate) in suspension has been done in this paper. Ethylene glycol dimethacrylate has been used as a crosslinker poly(vinyl-pyrrolidone) as a protective colloid, and a benzoyl peroxide ...
The cellular fatty acid composition of Bradyrhizobum japonicum and Sinorhizobium meliloti strains / Ćelijske masne kiseline sojeva Bradyrhizobum japonicum i Sinorhizobium meliloti
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
Microbial fatty acid analysis represents a simple and rapid method for identification of strains mainly for taxonomic purpose. Fatty acid composition in the whole cells and lipopolysaccharides in Rhizobiaceae were studied ...
Porous poly(methylmethacrylate) and poly(methylmethacrylate-co-acrylamide) / Porozni poli(metilmetakrilat) i poli(metilmetakrilat-co-akrilamid)
