Inverse gas chromatography of chromia, Part I: Zero surface coverage / Inverzna gasna hromatografija hromoksida, Deo I - nulta površinska pokrivenost
(Serbian Chemical Society, Belgrade, 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 heated at 1073 K in ...
Alumina/silica aerogel with zinc chloride as an alkylation catalyst / Alumosilikatni aerogel sa cink-hloridom kao katalizator za reakcije alkilovanja
(Serbian Chemical Society, Belgrade, 2001)
The alumina/silica with zinc chloride aerogel alkylation catalyst was obtained using a one step sol-gel synthesis, and subsequent drying with supercritical carbon dioxide. The aerogel catalyst activity was found to be ...
Electrochemical properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces / Elektrohemijske karakteristike i termička stabilnost epoksidnih kataforetskih prevlaka na aluminijumu i modifikovanim površinama aluminijuma
(Serbian Chemical Society, Belgrade, 2001)
The corrosion behavior of epoxy coatings electrodeposited on aluminum, as well as on electrochemically and chemically modified aluminum were investigated during exposure to 3 % NaCl. Electrochemical impedance spectroscopy ...
On the aqueous oxidation of polymetallic Cu-Zn-Pb gold-bearing sulphide ore in an autoclave
(CIM Bulletin, 2001)
The paper presents a study on the oxidation of polymetallic gold ore by oxygen in an autoclave. It presents optimum parameters of autoclave leaching of sulphide refractory ore in self-generated sulphuric acid solutions ...
Characteristics of natural isolates of lactic acid bacteria selected for construction of starter cultures for semi-hard cheese of the Trapist type
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2001)
Starter cultures (S12, S19 and S21) for semi-hard cheese of the Trapist type were constructed by using natural isolates of lactic acid bacteria (LAB) that were mostly isolated from home-made cheese. These starter cultures ...
Densification and crystallization behaviour of colloidal cordierite-type gels / Denzifikacija i kristalizacija koloidnih gelova kordijeritnog sastava
(Serbian Chemical Society, Belgrade, 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 densification ...
Identification of adsorption kinetics with dual mechanisms by nonlinear frequency response method
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
A characteristic example of the inability of the classical linear frequency response (FR) method to identify the correct kinetic mechanism is adsorption of n-hexane on silicalite-1. The linear FR has resulted in bimodal ...
Electrodeposition and characterization of Zn-Ni alloys as sublayers for epoxy coating deposition
(Springer, Dordrecht, 2001)
The chemical composition and phase structure of Zn-Ni alloys obtained by electrodeposition under various conditions were investigated. The influence of the deposition solution and deposition current density on the composition, ...
Electrochemical oxidation of carbon monoxide: From platinum single crystals to low temperature fuel cells catalysts, Part I: Carbon monoxide oxidation onto low index platinum single crystals / Elektrohemijska oksidacija ugljen-monoksida - od monokristala platine do katalizatora za niskotemperaturne gorivne galvanske spregove, I deo - oksidacija ugljen-monoksida na niskoindeksnim monokristalima platine
(Serbian Chemical Society, Belgrade, 2001)
The electrochemical oxidation of carbon monoxide and the interfacial structure of the CO adlayer (COads) on platinum low index single crystals, Pt(111), Pt(100) and two reconstruction of Pt(110), were examined using the ...
Mixing rules for excess free energy models / Pravila mešanja za modele dopunske slobodne energije
(Serbian Chemical Society, Belgrade, 2001)
lt Summary gt The thermodynamic representation of highly non-ideal mixtures containing non-polar and polar compounds that are similar or very dissimilar in size and shape, over large ranges of temperature and pressure, ...
