The effect of drying in spout fluid bed drier on lactic acid bacteria activity / Uticaj sušenja u fontansko-fluidizovanom sloju na aktivnost bakterija mlečne kiseline
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
The aim of this work was to obtain the stable - powdered polycomponent preparation based on fermented soybean extract that is supplemented with beetroot juice and yeast autolysate with preserved biological activity. Such ...
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 ...
The thermal degradation of poly(diethyl fumarate) / Termička degradacija poli(dietil fumarata)
(Association of Chemical Engineers of Serbia, 2001)
The kinetics and mechanism of the thermal degradation of poly(diethyl tumarate) (PDEF) were studied by thermogravimetry and analysis of the polymer residue. The characteristic mass loss temperatures were determined, as ...
Design of ion-exchange resins selective of caesium. Synergistic effect of macrocycle in phenolic resins
(Marcel Dekker Inc, New York, 2001)
The extraction of caesium by resorcinol based resins was investigated. At high hydroxide concentration ([OH-] = 0.15 M), the alkali-metal cations' sorption selectivity (determined in competitive extraction system) for ...
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 ...
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 ...
Oscillatory behavior in the electrochemical oxidation of formic acid on Pt(100): rotation and temperature effects
(Elsevier Science Sa, Lausanne, 2001)
We investigated the oscillatory behavior in the kinetics of formic acid electrooxidation on Pt(100) in 1 mM HClO4 solution. We studied the effect of different experimental parameters on the oscillatory behavior, viz. defined ...
Cellulosic fibres at the beginning of the twentyfirst century / Celulozna vlakna na pragu XXI veka
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2001)
The paper fives an overview of the current state in the field of various cellulosic fibres, such as cotton, flax, hemp, juta, viscosa and lyocell, as well as future prospects of these fibres. World production and consumption ...
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, ...
The thermal degradation of poly(ditetrahydrofurfuryl itaconate)
(Elsevier, Amsterdam, 2001)
The goal of this investigation was to study the thermal degradation of poly(ditetrahydro-furfuryl itaconate) (PDTHFI) by thermogravimetry (TG). The monomer was polymerized in bulk at 40 degreesC using AIBN as initiator. ...
