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 ...
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 ...
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 ...
Diversity and seasonal dynamics of culturable airborne fungi in a cultural heritage conservation facility
(Elsevier, 2021)
An extensive aeromycological survey was performed in the premises of a cultural heritage conservation facility to estimate fungal propagule concentrations in both indoor and outdoor air and seasonal dynamics with regard ...
Fatigue fracture analysis of helicopter landing gear cross tube
(Elsevier, 2021)
This paper presents the failure analysis results of the helicopter skid landing gear. The helicopter skid landing gear fractured while the helicopter was on the ground at the airport. The aft cross tube of the landing gear ...
Visible light promoted photoredox C(sp3)-H bond functionalization of tetrahydroisoquinolines in flow
(Royal Society of Chemistry, 2021)
A merger of organocatalysis and visible light photoredox catalysis performed in flow allowed access to a wide range of functionalizedN-aryl-substituted tetrahydroisoquinolines (THIQs) in a formal C-H oxidation/Mannich ...
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 ...
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 ...
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 ...
