Corrosion resistance of welded pipe in oil wells / Otpornost na koroziju zavarenih cevi u naftnim bušotinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Steel pipes in oil and gas wells are continuously exposed to the process of corrosion-assisted elevated temperatures and pressures prevailing in the interior of the tube. Corrosion can lead to significant reduction of ...
Selection of lactic acid bacteria strain for simultaneous production of α- and β-galactosidases / Izbor mlečnokiselinske bakterije za istovremenu proizvodnju α- i β-galaktozidaza
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Galactosidases are group of enzymes gaining increasing attention in recent times due to the fact they catalyse hydrolysis of galatose-containing oligosaccharide, which reduce digestibility of various food and feed products. ...
Organoclay-polymer nanocomposites / Organoglina-polimerni nanokompoziti
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved ...
Exergy concept and its implementation in the recycling of metals / Eksergijski koncept i njegova primena u recikliranju metala
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Modern industrial product design implies presence of many different materials. Consequently, in the recycling process, shredding and separation procedures are applied. However, all materials cannot be completely separated; ...
Nanostructured intrinsically conducting polymers formed by electrochemical synthesis / Nanostruktuirani elektroprovodni polimeri dobijeni elektrohemijskom sintezom
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still ...
Influence of the synthesis procedures on pt catalyst activity for ethanol electrooxidation reaction / Uticaj postupka sinteze na aktivnost platinskih katalizatora za reakciju elektrooksidacije etanola
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Carbon supported platinum catalysts for ethanol electrooxidation were synthesized by modified polyol synthesis method, assisted by microwave or reflux heating. Synthesized catalysts were characterized by XRD, STM and TGA ...
Impact of roughness of Zn-Mn coatings on corrosive stability / Uticaj hrapavosti Zn-Mn prevlaka na korozionu postojanost
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This paper involves electrochemical deposition of Zn-Mn coatings from four solutions. We measured their roughness and corrosion stability. We used cathodes made of steel of unknown composition that were licensed under the ...
Characterization of oxide coatings formed by plasma electrolytic oxidation of aluminum in sodium tungstate / Karakterizacija oksidnih slojeva dobijenih plazma elektrolitičkom oksidacijom aluminijuma u natrijum volframatu
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
This paper presents our recent research on morphology and phase composition of oxide coatings formed by plasma electrolytic oxidation of aluminum in 0.1 M sodium tungstate at constant current density of 15 mA/cm2 and ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
Procedures for processing of copper secondary raw materials / Postupci prerade sekundarnih sirovina bakra
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
The technological procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there ...
