(Универзитет у Београду, Хемијски факултет, 2011)
Zidna invertaza je izolovana iz ćelija kvasca Saccharomyces cerevisiae. Izolovan enzimski preparat je detaljno okarakterisan i dobijeni su pH optimum na 4,0, temperaturni optimum na 60°C, KM 30,93 mM, Vmax 11,64 mM/min i ...
Electrochemical oxidation of 2,4,6-trichlorophenol on iron-doped nanozirconia cerami / Elektrohemijska oksidacija 2,4,6-trihlorfenola na nano-cirkonijum - oksidnoj matrici dopiranoj gvožđem
(Beograd: Srpsko hemijsko društvo, 2021)
Solvothermaly synthesized zirconium oxide nanopowders, pure and
doped with various amounts of iron ions (1–20 %), were used as modifiers of
glassy carbon electrodes. The modified electrodes were tested in the reaction ...
Luminescent properties of praseodymium doped phosphate tungsten bronze
(Faculty of Management Herceg Novi, 2023)
Nowadays phosphate tungsten bronzes (PWBs) attract a lot of attention due to their interesting chemical, mechanical, and optical features. Moreover, tungsten bronzes as inert inorganic solids, with incorporated rare-earth ...
Synthesis and characterization of azido Zn(II) complex with the condensation product of 2-acetylpyridine and Girard's P reagent / Синтеза и карактеризација азидо комплекса Zn(II) са кондензaционим производом 2-ацетилпиридина и Жираровог П реагенса
(Belgrade, Serbia : Serbian Cristallographic Soceity // Beograd, Srbija : Srpsko kristalografsko društvo, 2023)
In the reaction of HLC1 with Zn(BF4)2.6H20 and NaN3 in molar ratio 1 : 1 : 4 in acetonitrile/water/methanol mixture of solvents, an mononuclear Zn(II) complex (1) was obtained, with composition [ZnL(N3)2]. In complex 1, ...
Comparison of the luminescence properties of phosphate-tungsten bronze and cerium doped phosphate-tungsten bronze
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
Phosphate-tungsten bronzes (PWBs) constantly attract a lot of attention owing to their interesting chemical, mechanical, and optical properties. Furthermore, tungsten bronzes as inert inorganic solids, exhibit interesting ...
The comparison of two methods used to observe a nonlinear system: potentiometry and holography
(Kragujevac, Serbia : Institute for Information Technologies, University of Kragujevac, 2023)
The transition from state I ( characterized by low iodide and iodine concentration) to state II (high iodide and iodine concentration) occurs in a nonlinear Briggs-Rauscher (BR) oscillatory reaction. This transition was ...
The investigation of chitin influence in laser induced deformation of butterfly wings
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2023)
The investigation of laser beam irradiation on different types of butterfly wings has been done previously by using the holographic method. The deformations due to the use of different laser wavelengths were observed. It ...
