Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, Belgrade, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
A linear solvation energy relationship study for the reactivity of 2-substituted cyclohex-1-enecarboxylic and 2-substituted benzoic acids with diazodiphenylmethane in aprotic and protic solvents / Proučavanje reaktivnosti 2-supstituisanih cikloheks-1- -enkarboksilnih i 2-supstituisanih benzoevih kiselina u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of 2-substituted cyclohex-1-enecarboxylic acids and the corresponding 2-substituted benzoic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 ºC. In order ...
Bioethanol production by immobilized Sacharomyces cerevisiae var. ellipsoideus cells
(African Journal of Biotechnology, 2009)
Bioethanol can be produced by fermentation of sugars from various waste agricultural materials. Whichever system for bioethanol production is chosen, the attention must be paid to the overall economics and energy consumption. ...

(Natl Inst Science Communication, New Delhi, 2005)
The rate constants for the reaction of diazodiphenylinethane with 2-substituted cyclohex-1-enylcarboxylic acids, determined in butan-1-ol, 2-methylpropan-1-ol and ethylene glycol, together with the rate constants determined ...
1,3-Propanediammonium [μ4-1,2,4,5-benzenetetracarboxylato(4-) ]copper(II) dihydrate with a microporous structure
(Serbian Chemical Society, 2005)
Crystal structure analysis of the title complex, (H3NC 3H6NH3)[Cu{C6H2(COO) 4}] ·2H2O, showed that the structure is built up from Cu(II) and tetradentate 1,2,4,5-benzenetetracarboxylate(4-) (btc) ions forming a 3D ...
The influence of electroless plated chromium on printing properties of aluminum offset printing plate
(Journal of the Serbian Chemical Society, 2002)
A method for the improvement of the printing properties of offset printing forms is presented. Specimens of technical aluminum were electrochemically roughened and treated in different alkaline solutions of chromium chloride ...
The sorption and crystallographic characteristics of alumina activated in a reactor for pneumatic transport / Sorpcione i kristalografske karakteristike alumine dobijene u reaktoru za pneumatski transport čestica
(Serbian Chemical Society, 2006)
Active transition alumina powders were obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute, two-phase flow regime in the temperature interval from 883 to 943 K with a residence time ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
A new dimensionless group for the estimation of the current density distribution in an electrochemical cell / Нова бездимензиона група за процену расподеле густине струје у електрохемијској ћелији
(Serbian Chemical Society, 2005)
A new dimensionless group for the estimation of the current density distribution in an electrochemical cell is defined as the ratio of the sum of the absolute values of the anodic and cathodic overpotentials to the overall ...
