Encapsulation of resveratrol in spherical particles of food grade hydrogels / Inkapsulacija resveratrola u sferične čestice na bazi hidrogelova dozvoljenih za upotrebu u hrani
(Institute for Food Technology, Novi Sad, 2017)
The paper reports about the preparation and characterization of hydrogel particles containing liposomes loaded with resveratrol as an active compound. The materials used for preparation of the particles were chosen to be ...
Changes in Pt-Rh catalysts in the working environment
(Institut za rudarstvo i metalurgiju, Bor, 2015)
The surface reconstruction on rhodium-platinum catalyst gauzes has been examined using the scanning electron microscope techniques. The nucleation and growth of large cage-like features, developed on the gauze surfaces ...
The Dependence of the Cost of Capital on Degree of Diversification
(Economic Laboratory Transition Research Podgorica-Elit, Podgorica, 2018)
The subject of this paper are theoretical and methodological aspects of determining the cost of capital on the example of two companies from the Energoprojekt system. The goal is to point out the most significant problems ...
The tribological performance of hardfaced/thermal sprayed coatings for increasing the wear resistance of ventilation mill working parts
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2015)
During the coal pulverizing, the working parts of the ventilation mill are being worn by the sand particles. For this reason, the working parts are usually protected with materials resistant to wear (hardfaced/thermal ...
Examination of the effectiveness of filtering half masks protection at various flow rates of aerosol contaminants / Ispitivanje efikasnosti zaštite filtrirajućih polumaski pri različitim protocima aerosolnih kontaminanata
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The possibility of air contamination by biological agents, by natural or artificial way, requires the improvement and use of different means for respiratory protection. The paper presents comparative filtration efficiency ...
Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Institut za ispitivanje materijala, Beograd, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Properties of cotton yarns after oxidation of potassium permanganate in an acidic environment / Svojstva pamučne pređe posle oksidacije kalijum-permanganatom u kiseloj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The impact of nonselective cellulose oxidation (cotton fibre) by potassium permanganate in acidic environment, with or without additional treatment by sodium metabisulfite, on change of sorption (silver ions sorption), and ...
Defining the ideality of the protective masks by the mathematical modeling method / Određivanje idealnosti zaštitnih maski metodom matematičkog modelovanja
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of ...
The influence of novel organic gold complex on photoresist layers of printed circuit boards
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this paper was to study the influence of organic gold complex based on mercaptotriazole on photoresist layers used in manufacturing of printed circuit boards (PCBs). Investigations were performed by immersion ...
Numerical simulation of temperature field in the vertical bridgman method crystal growth
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The mathematical model for heat transfer during the Bridgeman crystal growth, using the finite element method and the obtained result are presented. Some modifications to the method were introduced in order to incorporate ...
