Effects of air-lift reactor dimensions on its hydrodinamic characteristics / Uticaj geometrije pneumatskog reaktora sa spoljašnjom recirkulacijom na njegove hidrodinamičke osobine
(Association of Chemical Engineers of Serbia, 2010)
In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was ...
Application of plasma technology for the modification of polymer and textile materials / Mogućnost primene plazma tehnologije u modifikovanju polimernih i tekstilnih materijala
(Association of Chemical Engineers of Serbia, 2004)
Plasma treatment is based on the physico-chemical changes of the material surface and as an ecologically and economically acceptable process it can be an attractive alternative to conventional modifications. The possibilities ...
Electrochemical studies on LaNi4.15Co0.43Mn0.40Fe0.02 metal hydride alloy
(Elsevier Science Sa, Lausanne, 2000)
Electrochemical studies were performed on LaNi4.15Co0.43Mn0.40Fe0.02. alloy electrode. The kinetics of the electrochemical hydrogen absorption/desorption reaction was studied by DC polarization and AC impedance measurements. ...
Microwaves in organic chemistry and organic chemical / Primena mikrotalasne tehnike u organskoj hemiji i organskoj hemijskoj tehnologiji
(Association of Chemical Engineers of Serbia, 2005)
The usual way of applying heat to a chemical reaction is the use of a Bunsen burner, an oil or some other type of bath, or an electric heater. In inorganic chemistry, microwave technology has been used since the late 1970s ...
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 ...
Precipitation of the beta-phase and corrosion behavior of an al-6.8 wt.% mg alloy
(John Wiley & Sons, Chichester, 2012)
This study was performed on the Al-Mg alloy with the chemical composition: Al-Mg6.8-Mn0.51-Fe0.2-Si0.1. As-received cold rolled material (O-temper) was subjected to (i) cold rolling and annealing at 265 degrees C and 320 ...
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 ...
Thermal shock behavior of alumina based refractories
(Techna Srl, Faenza, 2002)
Temperature difference and fracture resistance parameters have been used to predict the thermal shock behavior. Alumina based commercial refractories with different content of Al2O3 from 28% to 78% were used. Thermal and ...
Utilization of supercritical carbon dioxide for development of antibacterial surgical sutures
(Elsevier B.V., 2022)
Outbreak of surgical infections and bacterial resistance against synthetic antibiotic has prompted research towards development of antibacterial medical devices. For that purpose, absorbable surgical sutures were impregnated ...
