Modified eggshell catalyst for transesterification of sunflower oil: The effects of catalyst loading on FAMEs content
(Belgrade : Serbian Chemical Society, 2019)
Modified highly active CaO catalyst (ESCHC-600) derived from waste chicken eggshells were prepared and used in the transesterification of sunflower oil. Eggshells were subjected to calcination-hydration-calcination (CHC) ...
Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...

Testing the applicability of diatom indices for ecological assessment of Balkan lakes
(Taylor & Francis, 2019)
During 2016-2017 six Balkan lakes were investigated: Sava Lake in Serbia, Ohrid Lake and Prespa Lake in North Macedonia and Albania, Great Lake in Albania, Biogradsko Lake and Crno Lake in Montenegro. Epilithic diatom ...
Dispersion effect in formic acid oxidation on PtAu/C nanocatalyst prepared by water-in-oil microemulsion method
(Amsterdam : Elsevier Science Bv, 2019)
Low loading PtAu nanoparticles supported on high area carbon were synthesized by water-in-oil microemulsion method and examined for formic acid and methanol oxidation. Prepared catalyst powder was characterized by Xray ...
Non-toxic poly(vinyl alcohol)/clay composites as electrode material for detection of 4-chlorophenol and 4-nitrophenol
(Elsevier, 2019)
Development of new electrode materials is necessary for the fabrication of sensors with low detection limits, high sensitivity and broad concentration range. Beside analytical parameters, the ability to replace rare and ...
Catalytic Activity and Stability of Pt and Pt-based Electrodes Towards the Formic acid Oxidation
(New York, USA : Nova Science Publishers Inc., 2019)
The development of direct formic acid fuel cells (DFAFCs) attracts attention because formic acid is a non-toxic and non-flammable liquid fuel and has a smaller crossover flux than methanol through polymer electrolyte ...
Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions
(Elsevier, 2019)
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon carbon cloth. The effects of different milling atmospheres, in the air and inert conditions, were investigated. Changes in kind ...
