The effect of the composition of the dispersing medium of oxide sols on the electro catalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes
(Journal of the Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
The effect of boron on the amount and type of carbides in chromium white irons
(Journal of the Serbian Chemical Society, 2002)
The effect of boron, in the amounts of 0.26, 0.39, and 0.59 wt.%, on the volume fraction and structure of carbides in Cr white irons was examined. It was demonstrated that the addition of boron can change the microstructural ...
Thermostability and surface morphology of nano- and micro-filled NBR/CSM and CR/CSM rubber blends
(Journal of the Serbian Chemical Society, 2004)
Acrylonitrile-butadiene rubber (NBR), polychloroprene rubber (CR). chlorosulphonated polyethylene rubber (CSM) and their blends were cross-linked with sulphur, ethylene-thiourea. magnesium oxide or their combination. The ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder
(Journal of the Serbian Chemical Society, 2002)
A possible way for the estimation of the interfacial energy of the copper - copper sulphate solution interface is proposed. The estimated value of (2.7 +/- 0.3) J cm(-2) and the derived equations which relate the specific ...
Structure and morphology of nano-sized W-Ti/Si thin films
(Journal of the Serbian Chemical Society, 2006)
Thin films were deposited by d.c. sputtering onto a Silicon Substrate. The influence of the W-Ti thin film thickness to its structural and morphological characteristics of a nano-scale were studied. The phase composition ...
Factorial design in isocratic high-performance liquid chromatography of phenolic compounds
(Journal of the Serbian Chemical Society, 2002)
A multifactor optimization strategy was utilized to predict the isocratic HPLC separation of nine phenols. The retention behavior was studied as a function of changing eluent (methanol - acetic acid) composition. The ...
Inverse gas chromatography of chromia. Part I. Zero surface coverage
(Journal of the Serbian Chemical Society, 2001)
The surface properties of the solid obtained from colloidal chromia were investigated by inverse gas chromatography (IGC), at zero surface coverage conditions. The solid samples I dried at 423 K and II healed at 1073 K in ...
Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants
(Journal of the Serbian Chemical Society, 2005)
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra ...
Autoxidation of tryptophan in aqueous solutions
(Journal of the Serbian Chemical Society, 2001)
Autoxidation of tryptophan was investigated in aqueous solutions by the gamma radiolytic technique. The oxygen uptake and formation of peroxide materials was followed as a function of pH, dose rate and concentration of ...
The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure
(Journal of the Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
