Novel azo pyridone dyes based on dihydropyrimidinone skeleton: Synthesis, DFT study and anticancer activity
(Elsevier, 2021)
Seven novel azo dyes with 2-pyridone and dihydropyrimidinone moieties have been synthesized and thoroughly characterized. The azo-hydrazone tautomerism has been investigated by experimental and theoretical approaches. ...
Reconstruction of palaeoenvironment and ancient human activities at Obrovac-type settlements (Serbia) using a geochemical approach
(Elsevier, 2022)
This study aims to determine the palaeoenvironmental characteristics and activity patterns of Obrovac-type archaeological sites in Western Serbia, dated to the Late Neolithic/Early Eneolithic period, ∼5th millennium BC. ...
Influence of surface coverage of kaolin with surfactant ions on adsorption of ochratoxin A and zearalenone
(Elsevier, 2021)
A natural kaolin from Serbia was modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) - (25, 50 and 90% of kaolin cation exchange capacity). Samples were denoted as OKR-25, OKR-50 and OKR-90. Several ...
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 ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Improving ethylene glycol transport properties by caffeine – Thermodynamic and computational evidence
(Elsevier, 2021)
In this article, detailed physicochemical characterization of ethylene glycol and caffeine + ethylene glycol mixtures is performed based on density, viscosity and refractive indices measurements in temperature range from ...
Eliminating dissolution of platinum-based electrocatalysts at the atomic scale
(Nature Publishing Group, 2020)
A remaining challenge for deployment of proton-exchange membrane fuel cells is thelimited durability of Pt-nanoscale materials that operate at high voltages during thecathodic oxygen reduction reaction. In this work, ...
Potencijal poljoprivredne biomase u sistemima proizvodnje biogasa u Republici Srbiji / Potential of agricultural biomass in biogas production systems in the Republic of Serbia
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
Biomasa predstavlja prema zvaničnim podacima najznačajniji potencijal obnovljivih izvora energije u Republici Srbiji. Ona čini oko 63% od ukupnog potencijala, ali za sada njena iskorišćenost nije na zadovoljavajućem nivou. ...

AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of ...
What is the preferred geometry of sulfur–disulfide interactions?
(Royal Society of Chemistry, 2020)
Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations. Statistical analysis of the geometrical data from the ...
