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 ...
Criteria for probiotic lactic acid bacteria selection / Kriterijumi za selekciju bakterija mlečne kiseline sa probiotičkim delovanjem
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
Criteria for selection of probiotic lactic acid bacteria are presented in this review paper. General characteristics, strain stability as well as functional and physiological aspects are pointed out in details. .
Physico-chemical characterization and antibacterial-activity of copper(II), zinc(II) and nickel(II) complexes with 2-methylbenzimidazole / Fizičko-hemijska karakterizacija i antibakterijska aktivnost bakar(II), cink(II) i nikal(II) kompleksa sa 2-metilbenzimidazolom
(Faculty of Technology, Novi Sad, 2001)
Chlorides and nitrates of copper(II), zinc(II) and nickel(II) react with 2-methylbenzimidazole to give complexes of the type [MX2(H2O))n(L).nH20 or [MX2(H2O)n(L)n]-nEtOH(M=Cu, Zn or Ni; X=Cl or NO3; L-=2-methylbenzimidazole; ...
Electrostatic generation of alginate microbeads loaded with brewing yeast
(Elsevier Sci Ltd, Oxford, 2001)
The substantial concern with the possible use of immobilized yeast cells for beer production is reduction of internal mass transfer resistance during continuous fermentation. One way to minimise this problem is to use ...
Nonlinear frequency response of nonisothermal adsorption systems
(Springer, Dordrecht, 2001)
A general method for the investigation of adsorption kinetics of nonlinear, nonisothermal systems, based on frequency response analysis, is presented. It is based on the definition of higher-order frequency response functions ...
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 ...
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 ...
NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene / NMR analiza 2-(2',3'-dihidro-1'H-inden-1'-il)-1H-indena
(Serbian Chemical Society, Belgrade, 2001)
1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling ...
Determination of the protective properties of electrodeposited organic coatings / Određivanje zaštitnih svojstava polimernih prevlaka dobijenih postupkom elektroforetskog taloženja
(Association of Chemical Engineers of Serbia, 2001)
Using electrochemical impedance spectroscopy, thermogravimetric analysis, gravimetric liquid sorption experiments, differential scanning calorimetry and optical microscopy, the corrosion stability of organic coatings was ...
Phase-transformation kinetics in triphasic cordierite gel
(Cambridge Univ Press, New York, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
