Densification and crystallization behaviour of colloidal cordierite-type gels
(Journal of the Serbian Chemical Society, 2001)
Three cordierite-type gels were prepared from an aqueous solution of Mg(NO3)(2). a boehmite sol and silica sols of very small particle sizes. The effect of varying the silica particle size on the crystallization and ...
The STM analysis of a silver mirror surface
(Journal of the Serbian Chemical Society, 2001)
In this work, the structure of a silver mirror surface was examined by the STM technique. It was shown that the Structural characteristics which enable a high degree of mirror reflection from this surface, which is very ...
Potentiometric application of boron- and phosphorus-doped glassy carbon electrodes
(Journal of the Serbian Chemical Society, 2001)
A comparative study was carried out of the potentiometric application of boron- and phosphorus-doped and undoped glassy carbon samples prepared at the same heal treatment temperature (HTT 1000 degreesC). The electrochemical ...
Extraction of uranyl nitrate, sulphate and chloride with tri-n-octyl amine (TOA) from aqueous solutions
(Journal of the Serbian Chemical Society, 2001)
Extraction of uranyl nitrate, chloride and sulphate with tri-n-octyl amine (TOA) in benzene as a function of the TOA concentration has been studied. The concentration based extraction equilibrium constants were calculated ...
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 ...
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 ...
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 ...
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 ...
