Nanocomposite powders for new contact materials based on copper and alumina
(Association of the Chemical Engineers of Serbia, 2008)
This paper is a contribution to characterization of Cu-Al2O3 powders with nanostructure designed for the production of dispersion strengthened contact materials. New materials with predetermined properties can be successfully ...
100 years of Bor smelter factory, RTB Bor, Serbia / Sto godina Topionice bakra u Rudarsko-Topioničarskom Basenu Bor, Srbija
(Savez inženjera i tehničara Srbije, Beograd, 2008)
The break through moment in evolution of human community is discover of some metals. Developing mining and metallurgy in eastern Serbia was depended of developing The Bor mining and metallurgical complex (RTB Bor). The ...
Surface characteristics and antibacterial activity of a silver-doped carbon monolith
(Natl Inst Materials Science, Ibaraki, 2008)
A carbon monolith with a silver coating was prepared and its antimicrobial behaviour in a flow system was examined. The functional groups on the surface of the carbon monolith were determined by temperature-programmed ...
The validity of the general polarization curve equation approximation for the process of metal deposition / Validnost jednačine aproksimacije opšte polarizacione krive za taloženje metala
(Serbian Chemical Society, Belgrade, 2008)
Digital simulation was employed for the solution of the general polarization curve equation of metal deposition processes. By approximating the dependence of the exchange current density on concentration with a linear ...
The immobilization of lipase on Sepabeads: Coupling, characterization and application in geranyl butyrate synthesis in a low aqueous system
(Association of the Chemical Engineers of Serbia, 2008)
Lipase from Candida rugosa immobilized on Sepabeads EC-EP was shown to catalyze the esterification of geraniol with butyric acid in a predominantly organic system. The immobilization procedure was adjusted to optimize the ...
Temperature dependence of the kinetics of oxygen reduction on carbon-supported pt nanoparticles / Temperaturna zavisnost elektrohemijske redukcije kiseonika na nanočesticama platine na ugljeničnom nosaču
(Serbian Chemical Society, Belgrade, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryo-gel. The specific surface area of the support was 517 m2 g-1, the Pt particles ...
Lipase-catalyzed biodiesel synthesis with different acyl acceptors / Primena novih acil akceptora u procesu enzimski katalizovane sinteze biodizela
(Faculty of Technology, Novi Sad, 2008)
Biodiesel is an alternative fuel for diesel engine that is environmentally acceptable. Conventionally, biodiesel is produced by transesterification of triglycerides and short alcohols in the presence of an acid or an ...
