Structure-Dependent Electrochemical Behavior of 2-Pyridone Derivatives: A Combined Experimental and Theoretical Study
(MDPI, 2023)
In this work, the electrooxidation ability of nine pyridones was evaluated using cyclic
(CV) and square-wave voltammetry (SWV) in Britton–Robinson (BR) aqueous buffer solutions on a
glassy carbon electrode (GC). The ...
Application of Micro-Arc Discharges during Anodization of Tantalum for Synthesis of Photocatalytic Active Ta2O5 Coatings
(MDPI, 2023)
Ta2O5 coatings were created using micro-arc discharges (MDs) during anodization on a tantalum substrate in a sodium phosphate electrolyte (10 g/L Na3PO4·10H2O). During the process, the size of MDs increases while the number ...
Effect of carbon support on the activity of monodisperse Co45Pt55 nanoparticles for oxygen evolution in alkaline media
(Frontiers Media SA, 2023)
Oxygen evolution reaction (OER) represents the efficiency-limiting reaction in water electrolyzers, metal-air batteries, and unitized regenerative fuel cells. To achieve high-efficiency OER in alkaline media, we fabricated ...
The influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2024)
This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple ...
Co supported chitosan-derived carbon-smectite catalyst in Oxone® induced at dye degradation
(Serbian Ceramic Society, 2023)
Catalytic degradation of tartrazine in the presence of Oxone® activated by a catalyst constituted of cobalt supported on a nanocomposite of smectite with chitosan-derived carbon was investigated. The catalyst was synthesized ...
Diversity and Ecology of Charophytes from Vojvodina ( Serbia ) in Relation to Physico-Chemical and Bioclimatic Habitat
(Basel, Switzerland : MDPI, 2023)
In Serbia, almost all charophyte species belong to one of the IUCN categories. This study aimed to gather more knowledge about their floristic richness, distribution and ecology. During the survey, 262 localities were ...
Rietveld crystal structure refinement of a natural rhombohedral grossular-andradite garnet from Serbia
(Polish Geological Institute - National Research Institute, 2022)
Four macroscopically visible B–E (rim) zones, within a large natural ferric grossular garnet of Grs58–64Adr36–42Sps2 composition, are described by means of Rietveld refinements of the crystal structures in a series of six ...
The influence of barium ferrite nanoparticles on morphological and mechanical properties of ethyl cellulose based nanocomposites
(Belgrade : Association for ETRAN Society, 2019)
This study presents preparation and characterization of ethyl cellulose based nanocomposites. Successful use of simple solvent casting technique provided nanocomposites with high loads of barium ferrite magnetic nanopowder ...
Early Paleozoic Cenerian (Sardic) geodynamic relationships of peripheral eastern north Gondwana affinities: revisiting the Ordovician of the Getic/Kuèaj nappe (eastern Serbia)
(Polish Geological Institute - National Research Institute, 2023)
Regional tectonic synthesis suggests that a segment of the bipartite eastern Gondwana-type Carpathian-Balkan nappe-stacked Getic/Kučaj/Supragetic basement (eastern Serbia) experienced Cambro-Ordovician Cenerian (Sardic) ...
Mechanical activation and silver supplementation as determinants of the antibacterial activity of titanium dioxide nanoparticles
(Elsevier, 2024)
Metals and metal oxides have subpar antibacterial activities compared to those of small-molecule antibiotics, yet there are hopes that with proper compositional and structural adjustments this gap might be bridged. In this ...
