Hydrogen evolution on Au/GC and PdAu/GC nanostructures in acid solution: AFM, XPS, and electrochemical study
(Elsevier, 2021)
HER was examined on various glassy carbon-supported Au and PdAu electrodes in acid solution. The Au/GC electrodes were obtained after Au was electrodeposited on a GC substrate by holding the potential for various times in ...
Aerogel Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 catalysts for hydrodesulphurisation of dibenzothiophene and 4,6-dimethyldibenzothiophene
(Elsevier, 2021)
Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 aerogel catalysts were synthesized using sol-gel method and supercritical drying in excess solvent, and investigated in the hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and ...
Controlling Pd-Catalyzed N-Arylation and Dimroth Rearrangement in the Synthesis of N,1-Diaryl-1H-tetrazol-5-amines
(American Chemical Society (ACS), 2021)
The Pd-catalyzed N-arylation method for the synthesis of eighteen N,1-diaryl-1H-tetrazol-5-amine derivatives is reported. By running the reactions at 35 °C, compounds were isolated as single isomers since the undesired ...
Autochthonous and international grape varieties grown in Serbia - Phenolic and elemental composition
(Elsevier, 2021)
The phenolic and elemental profiles of Serbian autochthonous grape varieties ‘Smederevka’ and ‘Plovdina’ were studied and compared with some international varieties. Total phenolic content and radical scavenging activity ...
A Novel Route for Electrolytic Production of Very Branchy Copper Dendrites under Extreme Conditions
(IOP Publishing Limited, 2021)
Copper electrodeposition in a form of powder was examined using the pulsating overpotential (PO) regime from the sulfate electrolyte without or with an addition of various concentrations of chloride ions. Morphological and ...
Influence of selective acid-etching on functionality of halloysite-chitosan nanocontainers for sustained drug release
(Elsevier, 2021)
The functionality of halloysite (Hal) nanotubes as drug carriers can be improved by lumen enlargement and polymer modification. This study investigates the influence of selective acid etching on Hal functionalization with ...
Natural Pigment from Madder Plant as an Eco-Friendly Cathode Material for Aqueous Li and Na-Ion Batteries
(IOP Publishing, 2021)
Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides an
examination of a potential replacement for commercial cathode material using a naturally occurring ...
Development of advanced floating poly(lactic acid)-based materials for colored wastewater treatment
(Elsevier, 2021)
The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Elsevier, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZMFA) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
The significance of the metal cation in guanine-quartet - metalloporphyrin complexes
(Royal Society of Chemistry, 2021)
The planarity and the appropriate size of the porphyrin ring make porphyrin derivatives ideal ligands for stacking to guanine quartets and they could thus be used as anti-cancer drugs. In this contribution we analyzed ...
