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 ...
Influence of heat transfer conditions on determination of thermal shock resistance of refractories / Uticaj prenosa toplote na određivanje termostabilnosti vatrostalnog materijala
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The goal of this thesis was to determine the thermal shock resistance of alumina based refractories in the case of a heat transfer conditions different from the standard conditions given by quenching test JUS. B. D.8 319. ...
Refining of corrosive insulating oils by selective liquid-liquid extraction process
(42nd International Conference on Large High Voltage Electric Systems 2008, CIGRE 2008, 2008)
In recent years copper sulphide formation in transformer windings has been recognized as one significant risk factor for operation of power transformers, due to number of failures which have occurred as a consequence of ...
Oxygen transport in tissue engineering systems: Cartilage and myocardium
(Fluid Dynamics and Materials Processing, 2007)
Efficient transport of oxygen is one of the main requirements in tissue engineering systems in order to avoid cell death in the inner tissue regions and support uniform tissue regeneration. In this paper, we review approaches ...
Doped gamma-Bi2O3: synthesis of microcrystalline samples and crystal chemical analysis of structural data
(Walter de Gruyter Gmbh, Berlin, 2007)
A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...

(Serbian Chemical Society, Belgrade, 2005)
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra ...
An experimental study of the partial oxidation of ethane to ethylene in a shallow fluidized bed reactor / Eksperimentalno ispitivanje parcijalne oksidacije etana do etilena u reaktoru sa plitkim fludizovanim slojem
(Serbian Chemical Society, Belgrade, 2007)
The partial catalytic oxidation of ethane to ethylene was investigated experimentally in a shallow fluidized bed. The performances of two catalyst types, pure γ-Al2O3 and V2O5/γ-Al2O3 particles 1.8 mm in diameter, were ...
