The HL ligand, (E)-2-(1-(thiazol-2-ypethylidene)hydrazine-1-carbothioamide, was obtained from the condensation reaction of thiosemicarbazide and 2-acetylthiazole in water. The reaction of the ligand HL with Fe(BF4)2.6H20 ...
Oxidation of 1,4-dihydropyridines catalyzed by recombinant bacterial laccase expressed in E. coli / Oksidacija 1,4-dihidropiridina katalizovana rekombinantnom bakterijskom lakazom eksprimiranom u E. coli
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
Laccases are a versatile class of enzymes with applications ranging from waste valorization to organic synthesis. We have tested whole-cell systems containing bacterial laccase as catalysts in the oxidation of 1,4-dihydr ...
Multicore flower-like magnetite for potential application in cancer nanomedicine
(Association of Metallurgical Engineers of Serbia (AMES), 2023)
Nanomaterials are intensively researched both from the fundamental aspect due to new properties at the nanoscale, as well as the aspect of their application in many areas of technology. Magnetic nanoparticles (MNPs) are ...
Koncentracija i biodostupnost toksičnih metala u zemljištu Srednjeg Banata (Vojvodina, Srbija)
(Visoka škola strukovnih studija, Beogradska Politehnika, 2017)
Stepen kontaminacije zemljišta toksičnim elementima definiše se u skladu sa važećim pravilnicima na teritoriji R. Srbije. Neki od definisanih elemenata su uvek toksični za biljke ili ljude (Pb, Cd, As, Hg, V, Sb, Be), a ...
