Oxidation of dibenzothiophene as a model substrate for the removal of organic sulphur from fossil fuels by iron(III) ions generated from pyrite by Acidithiobacillus ferrooxidans / Oksidacija dibenzotiofena kao model-supstrata za izdvajanje organskog sumpora iz fosilnih goriva dejstvom gvožđe(III)-jona generisanog iz pirita pomoću Acidithiobacillus ferrooxidans
(Serbian Chemical Society, 2007)
Within this paper a new idea for the removal of organically bonded sulphur from fossil fuels is discussed. Dibenzothiophene (DBT) was used as a model compound of organicmolecules containing sulphur. This form of ...
The effects of a magnetic field on the morphologies of nickel and copper deposits: The concept of 'effective overpotential' / Uticaj primenjenih magnetnih polja na morfologije taloga nikla i bakra - koncept 'efektivne prenapetosti'
(Serbian Chemical Society, 2007)
The morphologies of nickel and copper deposits obtained without applied magnetic fields, and with both parallel and perpendicular applied magnetic fields were examined by the scanning electron microscopy (SEM) technique. ...
Radical reactions of xanthates: Annulation of the cyclopentene ring / Radikalske reakcije ksantata : anelacija ciklopentenovog prstena
(Belgrade : Serbian Chemical Society, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Magnetic effects in electrochemistry / Magnetni efekti u elektrohemiji
(Serbian Chemical Society, 2005)
The effect of imposed magnetic fields onto the electrodeposition of magnetic (nickel) and non – magnetic (copper) metals was analysed. Also, magnetic properties of electrochemically obtained nanocontacts were examined. An ...
Metal powder electrolysis: The shape of powder particles as a function of the exchange current density and overpotential for hydrogen evolution reaction / Формирање металних прахова електролизом: облик честица као функција густине струје измене и пренапетости за реакцију издвајања водоника
(Serbian Chemical Society, 2020)
The short survey of the dependence of the shape of electrolytically produced powder particles on the exchange current density for metal deposition and overpotential for hydrogen evolution reaction is presented. The decrease ...
Oxygen reduction on single crystal platinum electrodes in phosphoric acid solutions / Redukcija kiseonika na monokristalnim platinskim elektrodama u rastvorima fosforne kiseline
(Belgrade : Serbian Chemical Society, 1999)
Oxygen reduction reaction has been studied on Pt low index planes in 0.1 M and 85% H3PO4 using hanging meniscus rotating disc electrode technique. The first-order kinetics of O2 reduction reaction was found for all three ...
Stereoselective synthesis of α-hydroxy-β-amino acids: The chiral pool approach / Stereoselektivne sinteze α-hidroksi-β-aminokiselina iz prirodnih hiralnih prekursora
(Serbian Chemical Society, 2004)
A method for the stereoselective homologation of -amino acids into syn-α-hydroxy-β-amino acids is described, based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the ...
Bioremediation of groundwater contaminated with petroleum hydrocarbons applied at a site in Belgrade (Serbia) / Bioremedijacija podzemnih voda zagađenih naftnim ugljovodonicima primenjena u blizini termo-energetskog postrojenja u Beogradu
(Belgrade : Serbian Chemical Society, 2020)
Due to their extensive use, petroleum hydrocarbons are among the most common groundwater contaminants. Compared to the traditional methods of physical pumping of contamination from the aquifer and subsequent treatment ...
