Influence of the heat treatment on the tribological characteristics of the Ti-based alloy for biomedical applications
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
The influence of diverse heat treatments on micro-structural and tribological characteristics of Ti-6Al-4V ELI (mass%) alloy, which is used as implant material in biomedical engineering, was investigated on a block-on-disc ...
Mathematical modeling of zinc ions biosorption by short hemp fibers / Matematičko modelovanje procesa biosorpcije jona cinka kratkim vlaknima konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2013)
Waste hemp fibers were used as an efficient biosorbent for removal of zinc ions from polluted water. In order to obtain the material with better sorption properties, short hemp fibers were chemically modified. The following ...
Activated carbon materials derived from hemp fibers in pesticide adsorption and water disinfection / Adsorpcija pesticida i dezinfekcija vode aktiviranim ugljeničnim materijalima na bazi vlakana konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2015)
By varying the parameters of carbonization and activation, different samples of hemp fibers based activated carbon were obtained. Optimal production conditions were selected based on the adsorption properties of activated ...
The influence of bonding agents in improving interactions in composite propellants, determined using the FTIR spectra / Uticaj vezujućih agenasa na poboljšanje interakcija u kompozitnim gorivima utvrđen korišćenjem FTIR spektara
(Military Technical Institute, Belgrade, 2009)
Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according ...

(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2010)
Research takes place in areas of Kosovska Mitrovica and Zvecan with the aim to determine content of following heavy metals: Pb, Cd, Cr, Hg, Zn and also pH values in surface water of Ibar river, underground waters (wells) ...
Analytical model of MIS structure in electron devices / Analitički model MIS strukture u elektronskim napravama
(Savez inženjera i tehničara Srbije, Beograd, 2010)
In this paper the new analytical model of MIS (Metal-Insulator -Semiconductor) structure, in microelectron devices, is proposed. Presented model is relatively simple and, at the same time, the results obtained by the ...
The electrochemical deposition and corrosion stability of Zn-Mn alloy coatings / Elektrohemijsko taloženje i koroziona stabilnost prevlaka Zn-Mn legura
(Inženjersko društvo za koroziju, Beograd, 2010)
The influence of the type of the deposition solution on the current efficiency during electrodeposition of Zn-Mn alloys was examined. The Zn-Mn alloys were deposited on steel from chloride, sulphate and pyrophosphate plating ...
Biosorption as a new biotechnology with an aim of protection and balanced use of biodiversity / Biosorpcija kao nova biotehnologija u funkciji očuvanja i uravnoteženog korišćenja biodiverziteta
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2010)
Rapid techno-economic development, without adequate protection of the environment, caused a number of emergence problems: pollution, waste, loss of biodiversity, introduction of invasive species, release of o genetically ...
