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 ...
Utilization of agro-industrial by-products as substrates for dextransucrase production by leuconostoc mesenteroides t3: Process optimization using response surface methodology / Iskorišćenje nus-proizvoda agro-industrije za proizvodnju dekstransaharaze pomoću bakterije leuconostoc mesenteroides t3: Optimizacija procesa metodom odzivnih površina
(Belgrade : Association of the Chemical Engineers of Serbia, 2021)
Dextransucrase (DS) is a glucosyltransferase (E. C. 2.4.1.5) that catalyzes the transfer of glucosyl residues from sucrose to dextran polymer and liberates fructose. This enzyme isassociated with a wide application range ...
Two new jatrophane diterpenes from the roots of Euphorbia nicaeensis / Два нова јатрофанска дитерпена из корена Euphorbia nicaeensis
(Serbian Chemical Society, 2021)
In the previous study fifteen jatrophane diterpenes were isolated from the Euphorbia nicaeensis latex. Fourteen of them have been shown to be potent P-glycoprotein (P-gp) inhibitor in two MDR cancer cells (NCI-H460/R and ...
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. ...
Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
