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 ...
Conditioning of the filament for diamond deposition by hot-filament chemical vapour deposition method
(Journal of the Serbian Chemical Society, 1998)
A tungsten filament, 0.12 mm in diameter, was conditioned by heating in a mixture of methane and hydrogen of three different concentration ratios. The filament was heated by an electric current. The procedure was carried ...
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 ...
Infrared spectra of uranyl compounds in alkali halide matrices: oxalates and acetates
(Journal of the Serbian Chemical Society, 1998)
The infrared absorption spectra of uranyl oxalate and acetate in KBr matrices in the 4000-250 cm(-1) range have been examined. Special attention was devoted to the dependence of the IR spetra on the sample treatment ...
Study of the effect of Mg(II) addition and the annealing conditions on the structure of mesoporous aluminum oxide using Plackett-Burman design
(Journal of the Serbian Chemical Society, 2015)
A statistical design was used to investigate the effect of various processing conditions on the structure of sol-gel derived Mg(II) doped alumina. Six process variables were selected based on the Plackett-Burman design: ...
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 ...
Sulfur retention by ash during coal combustion. Part I. A model of char particle combustion
(Journal of the Serbian Chemical Society, 2003)
A model for the combustion of porous char particles as a basis for modeling the process of sulfur retention by ash dining coal combustion is developed in this paper. The model belongs to the microscopic intrinsic models ...
