Temperature-dependent hydrogen electrochemistry on platinum low-index single-crystal surfaces in acid solutions
(Amer Chemical Soc, Washington, 1997)
The hydrogen evolution (HER) and the hydrogen oxidation reaction (HOR) were studied on platinum single crystals in a sulfuric acid solution over the temperature range 274-333 K. We found, for the first rime, that at a fixed ...
Thermogravimetric characterisation of poly(methyl methacrylate) photopolymerised by colloidal cadmium sulphide
(Springer, Dordrecht, 1997)
The thermal stability of poly(methyl methacrylate) (PMMA) photopolymerised using colloidal cadmium sulphide as the photoinitiator was studied by thermogravimetry (TG) and differential TG (DTG). The thermal stability of the ...
Size distribution of ultrafine spherical ceramic powders obtained by ultrasonic spray pyrolysis
(Trans Tech Publications Ltd., 1997)
Comparative analysis of experimentally determined particle size distribution and theoretically calculated aerosole drop size distribution (obtained on the basis of 3D model of spherical / elliptical waves generated by the ...
Preparation of thermoplastic starch
(Serbian Chemical Society, Belgrade, 1997)
Native starch and WX-starch, i.e., native starch enriched with amylopectin, were mixed with plasticizers and thermomechanically treated in a twin screw mixer in order to obtain thermoplastic starch. Ethylene glycol, propane ...
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 ...
The thermal degradation of polymethacrylonitrile with different end groups
(Springer, Dordrecht, 1997)
Polymethacrylonitrile (PMAN) was prepared by bulk, solution and precipitation polymerization. The thermal stability of the polymer, which is affected by the structure of the chain end groups, was studied by non-isothermal ...
