Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Phase equilibrium data for the hydrogen sulphide + methane system at temperatures from 186 to 313 K and pressures up to about 14 MPa
(Elsevier, 2014)
Isothermal vapour–liquid equilibrium data have been measured for the methane–hydrogen sulphide (CH4 + H2S) binary system at five temperatures from 186.25 to 313.08 K, and pressures between 0.043 and 13.182 MPa. The ...
New occurrence of wulfenite at the Stari Trg-Trepča ore deposit
(Belgrade : Serbian Geological Society, 2010)
Wulfenite (PbMoO4) is a rather rare mineral, and according to that, every new occurrence deserves considerable attention. This mineral was discovered at the Stari Trg-Trepča ore deposit in the paragenesis with galena, ...
Flocculation studies of natural quartz sample using anionic polyacrilamide
(Akademija nauka i umjetnosti Republike Srpske, 2019)
The waste sludge generated during processing of iron ore in the Omarska mine (Republika Srpska, Bosnia and Herzegovina) is fine-grained (<15μm), containing relatively high concentrations of iron, and quartz as its major ...

Phosphorylated kraft lignin based flame retardant: efficient method for improvement of lignin flame retardancy and mechanical action in polyester
(Belgrade : Military Technical Institute, 2018)
In this paper, the potential application of phosphorylated industrial kraft lignin (KLP) in improving flame
retardant properties of unsaturated polyester/KLP composites (UPe/KLP) was studied. KLP mass contents in UPe ...
Anisotropy of refractory concrete subjected to the thermal shock by using the surface analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Monitoring and analysis of the material anisotropy during the thermal shock of the refractory concrete was studied. The material was alumina based low cement castable pre-treated at 1300°C for 3 hours. Water quench test ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
The objective of this study was to monitor the behavior of fly ash originated from the power plant Nikola Tesla as a low cost absorbent for removal of copper ions from synthetic aqueous solutions. Fly ash, a potentional ...
Removal of copper, cadmium, and zinc from the mine wastewater in RTB Bor by low cost adsorbent fly ash
