Boron and phosphorus doped glassy carbon: I. Surface properties
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
Synthesis of spinel powders by the spray pyrolysis method
(Trans Tech Publications Ltd, Durnten-Zurich, 1997)
In this paper synthesis of spinel powders by the two-fluid spray pyrolysis method was performed. The influence of the precursors (AlCl3·9H2O and MgCl2·6H2O for S-1 powder and boehmite sol and MgCl2·6H2O for S-2 powder) on ...
Ion exchange of synthetic zeolite A with Cr(III) ions
(Serbian Chemical Society, Belgrade, 1997)
A series of chromium-exchanged zeolite A was prepared by ion-exchange using very dilute solution of a chromium(III) salt. The chromium(III) ions can replace up to 40% sodium cations. A significant lattice decomposition was ...
Low temperature processes during the synthesis of lanthanum lead borosilicate glasses
(Serbian Chemical Society, Belgrade, 1997)
Low temperature processes during the synthesis of PbO-B 2 O 3 -SiO 2 -La 2 O 3 glasses were studied by thermal analysis of the batch mixture of glasses and X-ray powder diffraction analysis of samples that crystallized ...
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions
(Serbian Chemical Society, Belgrade, 1997)
The kinetics of lead leaching from lead(II) sulphate in aqueous magnesium chloride solutions was studied. The lead leaching rates were measured using an agitated vessel at atmospheric pressure. The effects of the MgCl2 ...
Elimination of vanadium and arsenic from VKCs catalysts
(Marcel Dekker Inc, New York, 1997)
Vanadium and arsenic eliminations from an alkaline leaching solution of spent VKCs catalysts were studied. To this end, several commercial resins or polymers synthesized in the laboratory were evaluated in a solid-liquid ...
The influence of the sintering regime on the stability of the SmCo5 phase
(Elsevier, Amsterdam, 1997)
The purpose of this investigation was to establish the correlation between the sintering conditions (temperature and time) and the stability of the SmCo5 phase, expressed by the intensity of its most important diffraction ...
Temperature dependent oxygen electrochemistry on platinum low index single crystal surfaces in acid solutions
(Natl Research Council Canada, Ottawa, 1997)
Using the rotating ring-disk technique (RRDPt(hkl)E), the oxygen-reduction reaction (ORR) was studied in sulfuric acid solution over the temperature range 298-333 K. At the same temperature, the exchange current density ...
Synthesis and formation mechanism of submicrometre spherical cordierite powders by ultrasonic spray pyrolysis
(Chapman Hall Ltd, London, 1997)
Cordierite powders containing very pure submicrometre spherical particles have been synthesized by the ultrasonic spray pyrolysis. Aqueous solutions of silicic acid, Al(NO3)(3) . 9H(2)O and MgCl2 . 6H(2)O were used as ...
Development of an integrated system for air pollutant dispersion modelling
(Inderscience Publishers, 1997)
A complex expert system for air pollutant dispersion modelling (ScalEx) is currently being developed at Faculty of Technology and Metallurgy in Belgrade. The project goal is to develop a powerful software system as an ...
