Peracids oxidation of cholesta-5,8-dien-3β-yl acetate / Oksidacija holesta-5,8-dien-3β-il acetata sa perkiselinama
(Serbian Chemical Society, 2000)
Expoxidation of cholesta-5,8-dien-3β-yl acetate (1) with peracids takes place preferentially at the more highly substituted Δ8-olefinic double bond to give: (a) with monoperphthalic acid, 8α,9α-epoxycholest-5-en-3β-yl ...
The influence of pyrolysis type on shale oil generation and its composition (Upper layer of Aleksinac oil shale, Serbia)
(Serbian Chemical Soc, Belgrade, 2017)
The influence of pyrolysis type on the shale oil generation and its composition was studied. Different methods such as Rock-Eval pyrolysis, thermogravimetric analysis (TGA) and pyrolysis in the open and closed systems were ...
Non-isothermal kinetic characterisation of a gas-solid reaction by TG analysis / Neizotermalna kinetička karakterizacija reakcija gasnih i čvrstih reaktanata TG analizom
(Serbian Chemical Society, 2005)
A series of silica-supported Ni-catalyst precursors was synthesized, with different SiO2/Nimole ratios between 0.2 and 1.15. The reduction of all the prepared samples was studied by thermogravimetry (TG) in a hydrogen flow. ...
Influence of surface morphology on methanol oxidation at a glassy carbon-supported Pt catalyst / Uticaj površinske morfologije na oksidaciju metanola na platinskim katalizatorima sa podlogom od staklastog ugljenika
(Serbian Chemical Society, 2008)
Platinum supported on glassy carbon (GC) was used as a model system for studying the influence of the surface morphology of a Pt catalyst on methanol oxidation in alkaline and acidic solutions. Platinum was deposited by ...
Development and validation of a simple thin-layer chromatographic method for the analysis of p-chlorophenol in treated wastewater / Validacija tankoslojne hromatografije kao metode za jednostavno određivanje p-hlorfenola u tretiranoj otpadnoj vodi
(Serbian Chemical Soc, Belgrade, 2012)
A thin-layer chromatographic (TLC) method with densitometric detection was established for the quantification of p-chlorophenol in wastewater. Degradation efficiency of p-chlorophenol was monitored after each treatment of ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
New rhodium(III)-ED3AP complex: Crystal structure, characterization and computational chemistry / Нови родијум(iii)-ed3ap комплекс: кристална структура, карактеризација и компјутациона хемија
(Belgrade : Serbian Chemical Society, 2022)
Only one (trans(O5)-Na[Rh(ED3AP)]∙3H2O) of possible two isomers was synthesized and characterized by single crystal X-ray analysis, IR and UV–Vis spectroscopy. Computational analysis of both isomers was performed with three ...
To Professor Petar Pfendt, In calidum, et plurium retributivus memoriae: FTIR-ATR analysis of post stamps of the Principality of Serbia issued in 1866 and 1868 and their forgeries
(Belgrade : Serbian chemical society, 2022)
In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia ...
Drmno lignite field (Kostolac Basin, Serbia): Origin and palaeoenvironmental implications from petrological and organic geochemical studies / Ligniti ležišta Drmno (basen Kostolac) - poreklo i paleouslovi stvaranja na osnovu petrografskih i organsko-geohemijskih istraživanja
(Serbian Chemical Soc, Belgrade, 2012)
The objective of the study was to determine the origin and to reconstruct the geological evolution of lignites from the Drmno field (Kostolac Basin, Serbia). For this purpose, petrological and organic geochemical analyses ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
