Energy efficient pulse-reverse regimes of electrodeposition / Energetski efikasni pulsno-reverzni režimi galvanizacije
(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2017)
Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy ...
Non-destructive evaluation of sulfur-polymer composite behavior under induced destruction influence
(Institute for Multidisciplinary Research, University of Belgrade, 2015)
In order to avoid undesirable effects, caused by interactions between the material and environment, changes in properties of materials during their exploitation periods have to be determined. In this research, the induced ...
Damage level evaluation of zircon samples caused by cavitation erosion using image analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2017)
This study is focused on monitoring the degradation level of zircon based ceramic materials during exposure to cavitation. In addition to conventional degradation monitoring methods, weight loss measuring, the emphasis is ...
Cavitation damage of mullite ceramic: implementation of image analysis
(Bor : University of Belgrade - Technical Faculty in BorBor : Mining and Metallurgy Institute Bor, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200 °C. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
Valorization of secondary sulfur from oil refining process for sulfur concrete production
(Bor : University of Belgrade - Technical Faculty in Bor, 2015)
Modification of conventional building materials is commonly realized using different waste materials. In this research, the use of secondary sulfur as binding agent in concrete was analyzed. Sulfur concrete is a thermoplastic ...
Valorization of waste sulfur in synthesis of eco-friendly self-compacting concrete
(Union of Mechanical and Electrical Engineers and Technicains of SerbiaSociety for Renewable Electrical Power Sources, 2018)
Self-compacting concrete (SCC) typically contains a certain content of very fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with elemental waste sulfur since it is ...
Benchmark study for systems with double and single bonds
(Skopje : Society of chemists and technologists of Macedonia, 2016)
The interactions of model system with pi-bonds are important and have been studied with interest. Presence of pi-bonds can affect the properties and behavior of various systems and processes. For example, fatty acids, which ...
Mixed-mode resins: taking shortcut in downstream processing of raw-starch digesting α-amylases
(Serbian Biochemical Society (Belgrade), 2015)
Bacillus licheniformis 9945a α-amylase (BliAmy) has been described as potent enzyme for raw starch hydrolysis. Starch represents an inexpensive source for production of glucose, maltose syrups and fructose which are widely ...
Electric Properties of Biodegradable Copper Filled Poly(Lactide-co-Glycolide) Composites
(Zvornik, Republic of Srpska, B&H : Faculty of Technology, 2019)
The results of experimental studies of the properties of composite materials based on Poly(lactide-co-glycolide) (PLGA) matrix filled with electrolytic copper powder, having very high dendritic structure, are presented in ...
Oxidation of 1,4-dihydropyridines catalyzed by recombinant bacterial laccase expressed in E. coli / Oksidacija 1,4-dihidropiridina katalizovana rekombinantnom bakterijskom lakazom eksprimiranom u E. coli
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
Laccases are a versatile class of enzymes with applications ranging from waste valorization to organic synthesis. We have tested whole-cell systems containing bacterial laccase as catalysts in the oxidation of 1,4-dihydr ...
