Synthetic studies towards D-modified paclitaxel analogues / Sintetičke studije analoga paklitaksela sa modifikovanim D-prstenom
(Serbian Chemical Soc, Belgrade, 2012)
A synthetic sequence has been developed for the preparation of 9,10- di-O-diacetyl-4-desmethylene-4β-(3-butenyl)-4α-hydroxy-5-O-mesyltaxicin I- -1,2-carbonate 3, an intermediate in an attempted synthesis of a cyclobutane ...
Diastereoselective addition of alkenylchromium(III) reagents to Garner's aldehyde. The Nozaki-Hiyama-Kishi coupling approach to sphingosines and ceramides
(Serbian Chemical Soc, Belgrade, 2014)
Intermolecular Nozaki-Hiyama-Kishi coupling between alkenylchromium(III) reagents, derived from either (E)-(2-bromoethenyl)benzene or (E)-1-iodo-1-pentadecene, and the conformationally rigid Garner's aldehyde resulted in ...
Sorption of different phenol derivatives on a functionalized macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite
(Serbian Chemical Society, 2014)
Macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite was prepared by radical suspension copolymerization. Nanocomposite was functionalized with diethylenetriamine ...
Electrocatalytic properties of Pt-Bi electrodes towards the electro-oxidation of formic acid / Elektrokatalitička svojstva Pt-Bi elektroda u oksidaciji mravlje kiseline
(Serbian Chemical Society, 2013)
Formic acid oxidation was studied on two Pt-Bi catalysts, i.e., Pt2Bi and polycrystalline Pt modified by irreversible adsorbed Bi (Pt/Biirr) in order to establish the difference between the effects of Biirr and Bi in the ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Biodiesel synthesis using K2CO3/Al-O-Si aerogel catalysts / Sinteza biodizela katalizovana alumosilikatnim aerogelom sa K2Co3
(Serbian Chemical Society, 2010)
In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol-gel method, which was followed by drying ...
Supercapacitors based on graphene/pseudocapacitive materials
(Serbian Chemical Society, 2017)
Composites of graphene and SnO2 were successfully prepared by a single step simultaneous synthesis of SnO2 and reduction of graphene oxide (GO). Three different compositions of precursor solution resulted in different ...
Pore surface fractal analysis of PEG and La(III)-doped mesoporous alumina obtained by the sol-gel method / Fraktalna analiza površine mezoporoznog aluminijum(III)-oksida sa dodatkom PEG i La(III) dobijenog sol-gel postupkom
(Serbian Chemical Society, 2010)
Active porous alumina was prepared via a sol-gel method and subjected to thermal treatment in the temperature range 500-1200 °C. The addition of lanthanum effectively inhibited the surface area loss of the aluminas. Fractal ...
Organobentonites as multifunctional adsorbents of organic and inorganic water pollutants
(Serbian Chemical Society, 2014)
The aim of this study was to find a low cost, easy to synthesize and efficient adsorbent for the simultaneous adsorption of both organic and inorganic pollutants (including textile dyes, toxic metals, etc.). The starting ...
Fruska Gora mountainous environments - assessing the impact of geological setting and land use on soil properties
(Serbian Chemical Soc, Belgrade, 2016)
On a global scale, it was found that the surface of the vulnerable land and land affected by degradation has been increasing in the last decades and that unsustainable land management is one of the key drivers of land ...
