13C- and 1H-NMR substituent-induced chemical shifts in N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones / Supstituentima izazvana 13C- i 1H-NMR hemijska pomeranja N(1)-(4-supstituisani fenil)-3-cijano-4,6-dimetil-2-piridona
(Serbian Chemical Society, Belgrade, 2008)
The 13C- and 1H-NMR chemical shifts of thirteen N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones were measured in deuterated dimethyl sulfoxide (DMSO-d6). The correlation analysis for the substituent-induced ...
Characterization and degradation of pectin derived from Budimka apple / Degradacija i karakterizacija pektina jabuke sorte budimka
(Serbian Chemical Society, Belgrade, 2008)
The characterization of apple pectin and its oligogalacturonic fractions derived from the autochthones apple variety Budimka, characteristic for central Serbia, is described in this paper. After extraction, the apple pectin ...
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 ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition / Jonska ravnoteža u sistemu CuSO4-H2SO4-H2O i formiranje strukture pčelinjeg saća elektrohemijskim taloženjem bakra
(Serbian Chemical Society, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
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 ...
