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 ...
Preparation of basalt-based glass ceramics
(Journal of the Serbian Chemical Society, 2003)
Local and conventional raw materials-massive basalt from the Vrelo locality on Kopaonik mountain-have been used as starting materials to test their suitability for the production of glass-ceramics. Crystallization phenomena ...
Stabilization of Tc-99m radiopharmaceuticals by chemical additives
(Journal of the Serbian Chemical Society, 2001)
The reliability and applicability of the preparation of the three, for nuclear medicine very important, Tc-99m-radiopharmaceuticals from the inactive (technetium-cold) kit solutions were tested. Each examined commercial ...
Surface roughness minimum: Ag thin layer deposited on a glass
(Journal of the Serbian Chemical Society, 2001)
In this paper the results of an examination of the surface roughness and morphology dependence of silver thin films up to 100 nm thick deposited on a microscope glass on the deposition rate and on the deposition time are ...
The improvement of the detection power of a U-shaped DC plasma
(Journal of the Serbian Chemical Society, 2001)
Optimization of the operating parameters of U-shpaed DC arc plasma and spectrometer parameters has been undertaken to explore the possibilities of improving its detection power. It is demonstrated, with a U-shaped are as ...
Synthesis of in situ reinforced silicon nitride composites
(Journal of the Serbian Chemical Society, 2004)
The objective of this work was to investigate the effect of two different sintering additives (CeO2 and Y2O3 + Al2O3), sintering time and amount of beta-Si3N4 seeds on the densification. mechanical properties and microstructure ...
