Dispersion effect in formic acid oxidation on PtAu/C nanocatalyst prepared by water-in-oil microemulsion method
(Elsevier, 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 ...
Investigation of lipophilicity and pharmacokinetic properties of 2-(methoxy) phenylpiperazine dopamine D2 ligands
(Elsevier, 2019)
Reversed-phase thin-layer chromatography and micellar thin-layer chromatography were used in order to investigate retention behaviour and to determine lipophilicity of series of 2(methoxy)phenylpiperazine dopamine D2 ligands ...
Fatigue endurance design of plates with two semicircular edge notches and one quarter-elliptical corner crack or through-the-thickness crack
(Elsevier, 2019)
This paper presents an investigation on the failure of plates with double-edge notches and fatigue damage. The
main aim is to develop a computational model for estimating the behaviour of a quarter-elliptical corner crack ...
Copper electrorefining from anodes with non-standard content of Ni, Pb, Sb and Sn
( New York, USA : Nova Science Publishers Inc., 2019)
Copper anodes with non-standard nickel, lead, antimony and thin content are used for refining by the standard electrochemical process. The waste solution from standard copper electrorefining process is used as working ...
Briggs-Rauscher reaction as a novel electrochemical detector for phosphate tungsten and phosphate molybdenum bronzes
(Elsevier, 2019)
Briggs-Rauscher (BR) oscillatory reaction is a chemical system very sensitive to different analyte addition. Changes in oscillatory dynamics, by analyte addition, could be successfully used for the determination of analyte ...
Synthesis and characterization of octenyl succinic anhydride modified levan
(10th European Symposium on Biopolymers, Straubing, Germany, September 25-27, 2019, Program Abstracts, 2019)
The aim of the present study is to optimize the synthesis of OSA-levan derivative.
Degradation of α-nitroso-β-naphthol by UVA-B activated peroxide, persulfate and monopersulfate oxidants in water
(Elsevier, 2019)
Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B ...
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 ...
Dehydrogenative C(sp3)–H bond functionalization of tetrahydroisoquinolines mediated by organic oxidants under mild conditions
(Royal Society of Chemistry (RSC), 2019)
The organocatalyzed Mannich reaction of unsubstituted and N-aryl-substituted tetrahydroisoquinolines (THIQs) and the Strecker reaction of several N-aryl-substituted THIQs through dehydrogenative C(sp3)–H bond functionalization ...
Dvostrano vlažno hemijsko nagrizanje Pyrex stakla
(Belgrade : University of Belgrade - Institute of Chemistry, Technology and Metallurgy, 2019)
Vlažnim hemijskim nagrizanjem u vodenom rastvoru HF (49%) se mogu napraviti i
različite 3D strukture od Pyrex stakla koje daju još jedan stepen slobode u projektovanju senzora i aktuatora. Ovaj tehnološki proces omogućava ...
