The effect of the particle shape and structure on the flowability of electrolytic copper powder I: Modeling of a representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha I - modelovanje reprezentativne čestice praha
(Serbian Chemical Society, 2003)
One of the most important properties of copper powder is its flow ability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
The critical apparent density for the free flow of copper powder / Kritična nasipna masa za tečenje praha bakra
(Serbian Chemical Society, 2003)
A method for the determination of the critical apparent density, which permits the free flow of electrodeposited copper powder is discussed. It was found that powders the apparent density of which were larger than 2.3 g/cm3 ...
Effects of substituents on the 1H-NMR chemical shifts of 3-methylene-2-substituted-1, 4-pentadienes / Efekti supstituenata na 1H-NMR hemijska pomeranja 3-metilen-2-supstituisanih-1,4-pentadiena
(Serbian Chemical Society, Belgrade, 2003)
The principle of linear free energy relationships was applied to the 1H chemical shifts of the β-vinyl proton atoms of 3-methylene-2-substituted-1,4-pentadienes. The correlations of the proton chemical shifts with Swain ...
The role of the concentration profile of titanium oxide on the electrochemical behavior of RuO2-TiO2 coatings obtained by the sol-gel procedure / Uloga koncentracionog profila titan-oksida u elektrohemijskom ponašanju RuO2-TiO2 prevlaka dobijenih sol-gel postupkom
(Serbian Chemical Society, Belgrade, 2003)
In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case ...
The kinetics of the reactions of 2-substituted nicotinic acids with diazodiphenylmethane in various alcohols / Kinetika reakcija 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u različitim alkoholima
(Serbian Chemical Society, Belgrade, 2003)
The rate constants of 2-substituted nicotinic acids in reaction with diazodiphenylmethane (DDM) in eight alcohols at 30 ºC have been determined. In order to explain the obtained results through solvent effects, the second ...
Electrochemical oxidation of carbon monoxide: From platinum single crystals to low temperature fuel cells catalysts - Part II: Electrooxidation of H2, CO and H2/CO mixtures on well characterized PtMo alloy / Elektrohemijska oksidacija ugljen-monoksida - od monokristala platine do katalizatora za niskotemperaturne gorivne galvanske spregove - II deo: Elektrohemijska oksidacija H2, CO I H2/CO smešama okarakterisanim PtMo legurama
