Entropy change of open thermodynamic systems in self-organizing processes
(Society of Thermal Engineers of Serbia, 2014)
The thermodynamic models available in the literature predict that during self-organizing processes the entropy of a cell considered as an open thermodynamic system
decreases. This prediction leads to conclusion that cell ...
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 ...
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 ...
Comparison of the crystallographic-chemical characteristics of sphalerites from the Kiževak ore deposit with some other deposits, part I: Preliminary reconsideration about their formation conditions / Поређење кристалографско-хемијских карактеристика сфалерита из рудног лежишта кижевак са неким другим рудним лежиштима, део I: релиминарно разматрање услова њиховог постанка
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of Serbia, 2017)
Crystallographic-chemical characteristics for sphalerites from the ore deposit Kiževak were used for the comparison with the corresponding characteristics of some other ore deposits: Šuplja Stijena-Brskovo, Lece, Selanac, ...
Comparative Study of the Mineral Composition and Its Connection with Some Properties Important for the Sludge Flocculation Process-Examples from Omarska Mine
(MDPI, 2018)
Studied sludge samples are composed of major goethite and quartz; less clay minerals;
and minor magnetite, hematite, clinochlore and todorokite. They have quite similar qualitative,
but different semi-quantitative ...
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 ...
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 ...
Macroscopically-zoned grandite from the garnetite skarn of Meka Presedla (Kopaonik Mountain, Serbia)
(John Wiley & Sons, Inc., 2012)
The macroscopically-zoned grandite from the garnetite skarn of Meka Presedla (Kopaonik Mountain, Serbia) was studied with optical microscopy, electron microprobe analysis (EMPA), Fourier transform infra-red (FT–IR), and ...
The dispersion-flocculation behaviour of the natural raw clay samples from Omarska mine / Понашање природних узорака глине из рудника Oмарска у процесима дисперзије и флокулације
(Академија наука и умјетности РС, 2019)
In present paper, studied were the dispersion-flocculation behaviour of the primary natural raw „clay samples” from Omarska mine (Republic of Srpska, Bosnia and Herzegovina). Namely, our previous results showed that during ...
