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, ...
Crystal structure and chemical composition of ludwigite from Vranovac ore deposit (Boranja Mountain, Serbia)
(John Wiley & Sons, Inc., 2012)
The crystal structure of ludwigite from Vranovac ore deposit (Boranja Mt., Serbia) was refined using the X-ray powder diffraction (XRPD) Rietveld method in the space group Pbam to a final RB=7.45% and RF=5.26%. It has the ...
Evaluation of leachate pollution index of urban municipal landfill site in Novi Sad, Serbia
(Osijek, Croatia : Josip Juraj Strossmayer University of Osijek, Faculty of Food Technology Osijek / Osijek, Hrvatska : Sveučilište Josipa Jurja Strossmayera u Osijeku, Prehrambeno-tehnološki fakultet Osijek, 2019)
Leachate samples were collected during the one year monitoring campaign, on municipal solid waste landfill in Novi Sad, Serbia. Determination of T, pH, EC, DO, BOD5, COD, NO2-N, NO3-N, NH4-N, Tot N, Tot P, B, SO4 2-, KMnO4, ...
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 ...
Electrochemical lithiation/delithiation kinetics and capacity of phosphate tungsten bronze and its chemically pre-lithiated derivatives in aqueous solutions
(Springer, 2016)
Monophosphate bronze (PW8O26, WPB) was synthesized by low-temperature (650 °C) heating of 12-tungstophosphoric acid (WPA). Its lithiated derivative with a low lithium content (Li3-WPB) was synthesized by heating lithium ...
Comparison of the crystallographic-chemical characteristics of sphalerites from the Kiževak ore deposit with some other deposits, part II: Construction of the four-component a0-FeS-P-T diagram (option I) and determination of the formation conditions / Поређење кристалографско-хемијских карактеристика сфалерита из рудног лежишта кижевак са неким другим рудним лежиштима, део ii: онструисање четворо-компонентног a0-fes-p-t дијаграма (опција I) и одређивање услова постанка
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of Serbia, 2018)
Same as in the I part of these investigations (Tančić, 2018), crystallographic-chemical characteristics for sphalerites from the ore deposit Kiževak were used for the comparison with the corresponding characteristics of ...
Image analysis technique for evaluating damage evolution and predicting mechanical strength of concrete structures under corrosion conditions
(Nova Science Publishers, Inc., 2014)
The degradation of concrete structures, which progresses as time passes, is caused by
external factors such as chemical, physical and mechanical interferences. In the case of
chemical deterioration, various ions penetrate ...

(Društvo za integritet i vek konstrukcija / Society for Structural Integrity and Life, 2013)
Fenomen integriteta konstrukcija u heritologiji povezan je sa teorijom prostora, teorijom restauracije, kao i zahte-vima održivog razvoja, pa heritološki pogled na integritet konstrukcija monumentalnih dela savremene ...
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 ...
