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. .
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 ...
Effects of plastic deformation on the properties of W-Ni-Fe heavy alloys
(International Institute for the Science of Sintering, Beograd, 2001)
The effects of reduction in area due to rotary forging on the structure, physical and mechanical properties of 92,5W-5Ni-2,5Fe heavy alloy rods have been presented in this paper. Sintered rods (20mm) were rotary forged ...
Synthesis and evaluation of resorcinol-based ion-exchange resins for the selective removal of cesium
(Marcel Dekker Inc, New York, 2001)
Control of the reaction conditions during the alkaline polycondensation of resorcinol with formaldehyde leads to polymeric resins with improved capacity toward caesium. The resins obtained are characterized by determining ...

The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
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 ...
The study of iron chlorination from bauxite for its enrichment
(Munksgaard Int Publ Ltd, Copenhagen, 2001)
The possibility of enriching bauxite by removing iron in low-temperature chlorination by gaseous chlorine in the presence of carbon as a reducer from coke and carbon monoxide, is investigated. Thermodynamic analysis points ...
