Assessment Of Toxic And Trace Elements (As, Cd, Cu, Cr, Hg, Ni, Pb, Sr, Zn) In Zooplankton From Carp Fish Ponds / Analiza koncentracije toksičnih i esencijalnih elementa (As, Cd, Cu, Cr, Hg, Ni, Pb, Sr, Zn) u zooplanktonu sa šaranskog ribnjaka
(7. International Conference “Water & Fish” Faculty of Agriculture, Belgrade-Zemun, Serbia, June, 10, 2015)
U poslednjih 20 godina zagađivanje slatkovodnih ekosistema toksičnim elementima je u porastu širom sveta. Zagađenjem su pogođeni pre svega izvori za vodosnabdevanje stanovništva i životno okruženje, ali i industrija kao i ...
Structure and mechanical properties of polyurethane/organoclay nanocomposites
(Belgrade : Society of Physical Chemists of Serbia, 2022)
Polyurethane/organoclay nanocomposites (PUNs) based on 4,4’-diphenylmethane diisocyanate
(MDI) and 1,4-butanediol (BD) as the components of the hard segments (HS) and α,ω-

Antibacterial activity of copper nanoparticles
(Society of Physical Chemists of Serbia, 2014)
Copper nanoparticles (CuNPs), with an average particle size of about 5 nm,
was prepared by the simple chemical reduction procedure. TEM and UV–
Vis spectroscopy contributed to the analysis of size and optical properties ...
Simultaneous degradation of two textile dyes Orange G and Basic blue 41
(Serbian Ceramic Society, 2023)
Cobalt-doped alumina catalyst was tested in peroxymonosulfate-induced degradation of two
textile dyes: anionic-Orange G (OG) and cationic-Basic Blue 41 (BB). Oxone®, mixed salt
containing peroxymonosulfate as an active ...
Thermodynamic and kinetic study of nicotine adsorption on acid-modified smectite
(Serbian Ceramic Society, 2022)
Kinetic and thermodynamic parameters of nicotine adsorption onto acid-activated standard
Wyoming clay were investigated to obtain the optimum conditions for adsorption. The
nicotine adsorptions were performed in a batch ...
Analysis of diterpenoids from the latex of E. seguieriana Neck. subsp. seguieriana by liquid chromatography–electrospray ionisation mass spectrometry
(Belgrade : University of Belgrade - Faculty of Agriculture, 2022)
In this study, we analysed the chloroform extract of the latex of E. seguieriana Neck. subsp.
seguieriana collected on Deliblato sand in flowering season by reversed-phase liquid chromatography–electrospray ionisation ...
Novel crosslinked polyurethanes based on hyperbranched polyesters
(Society of Physical Chemists of Serbia, 2010)
The polyurethane (PU) elastomers based on hydroxy-terminated hyperbranched polyester (BH-20) and 4,4-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxyl-terminated ethylene oxide-poly(dimethylsiloxane)-ethylene ...
Combustion of waste thermobaric explosive under controlled conditions as a source of energy / Sagorevanje otpadnog termobaričnog eksploziva pod kontrolisanim uslovima kao izvor energije
(Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), 2023)
Thermobaric explosive mixtures are recently widely studied due to their specific energetic effects,
especially regarding thermal output during the post-detonation combustion phase. Most of these
mixtures contain as a ...
Methanol electrooxidation on carbon-supported binary and ternary platinum catalysts / Elektrooksidacija metanola na binarnim i ternarnim platinskim katalizatorima na ugljeničnom nosaču
(Serbian society of corrosion and materials protection (UISKoZaM) / Udruženje inženjera Srbije za koroziju i zaštitu materijala, 2023)
One of the most popular alternative sources of energy are direct methanol fuel cells (DMFCs) with platinum-based catalysts due to their non-toxicity, reduced emissions of hazardous pollutants and high energy density. ...
