Comparison of properties of silver-metal oxide electrical contact materials
(Technical Faculty, Bor, 2012)
Changes in physical properties such as density, porosity, hardness and electrical conductivity of the Ag-SnO2 and Ag-SnO2In2O3 electrical contact materials induced by introduction of metal oxide nanoparticles were investigated. ...
Possible Mechanism of Pectin-Derived Oligosaccharides Influence on Gut Microbiota / Predloženi mehanizam uticaja oligosaharida dobijenih iz pektina na intestinalnu mikrobiotu
(Belgrade: University of Belgrade, 2018)
We prepared pectin-derived oligosaccharides (apple and citrus) and polygalacturonic acid-derived oligosaccharides, using alkaline hydrolysis by hydrogen peroxide, and analyzed them by Fourier Transform Infrared spectrometry. ...
Oxygen Reduction on Au(100)-like Polycrystalline Gold Electrode in Alkaline Solution
(Esg, Belgrade, 2016)
Catalytic properties of polycrystalline gold, Au(poly), were examined for the oxygen reduction reaction in alkaline solution using the rotating disc electrode technique. On electrochemically prepared Au(poly), oxygen ...
In vitro evaluation of antiproliferative properties of novel organotin(IV) carboxylate compounds with propanoic acid derivatives on a panel of human cancer cell lines
(MDPI, 2021)
The synthesis of novel triphenyltin(IV) compounds, Ph3SnLn (n = 1–3), with oxaprozin (3-(4,5-diphenyloxazol-2-yl)propanoic acid), HL1, and the new propanoic acid derivatives 3-(4,5bis(4-methoxylphenyl)oxazol-2-yl)propanoic ...
Biodiversity overview of soda pans in the Vojvodina region (Serbia)
(Geographical Institute "Jovan Cvijic", SASA, 2018)
Due to their specific physical and chemical properties of water and soil soda pans of the
Vojvodina region represent a unique type of habitats. Salinity is a major structuring factor which
strongly affects species richness. ...
Application of machine-learning algorithms for better understanding of tableting properties of lactose co-processed with lipid excipients
(MDPI, 2021)
Co-processing (CP) provides superior properties to excipients and has become a reliable option to facilitated formulation and manufacturing of variety of solid dosage forms. Development of directly compressible formulations ...
Experimental Investigation of Phase Equilibria in the Bi-Cu-Ge System
(Brazil : SCI FLO, 2021)
Phase diagram of the Bi-Ce-Ge ternary system has been investigated experimentally and thermodynamically extrapolated by using Pandat software. Experimental results were obtained using differential thermal analysis (DTA), ...
Mechanochemical Preparation of CaO·ZnO – catalyst for Fatty Acids Methyl Esters Synthesis
(Belgrade : Serbian Ceramic Society, 2012)
One of the catalysts that show excellent activity in the methanolysis of vegetable oil under moderate reaction conditions is the mixture of CaO and ZnO oxides. In this study CaO•ZnO catalyst was synthesized by mechanochemical ...
Diatoms – invisible residents of Resavska Cave (eastern Serbia)
(Postojna, Slovenia : Organizing Commitee, 2nd Dinaric Symposium on Subterranean Biology, 2019)
Diatoms (Bacillariophyta) are widespread microorganisms that were found in different aquatic ecosystems, but also in other habitats, such as stone substrates exposed to air. There diatoms thrive with other phototrophic ...
Microbial degradation of petroleum hydrocarbons - in vitro study
(Federation of European Microbiological Societies (FEMS), 2020)
Pollution of the environment by petroleum products is a global problem, since its extensive exploitation in broad areas.
Microorganisms can degrade or transform toxic, petroleum derivates into harmless products with high ...
