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 ...
Stress analysis in hydroxyapatite/poly-L-lactide composite biomaterials
(Elsevier, Amsterdam, 2001)
A three-dimensional (3D) finite element (FE) analysis of the stress concentration factor (SCF) in biocomposite model cell has been performed. The model composite consisted of a hydroxyapatite hard particle (HAp) embedded ...
Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of the Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
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 ...
Development of steels for fabrication of welded constructions with improved safety / Razvoj čelika za izradu zavarenih konstrukcija povišene sigurnosti
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2001)
Physical and metallurgical basis of historical steel development and some modern solutions for specific applications, together with predictions and projections of future development are reviewed in this paper. Undoubtedly, ...
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; ...
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 ...
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 ...
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 ...
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 ...
