Controllable synthesis of Fe3O4-wollastonite adsorbents for efficient heavy metal ions/oxyanions removal
(Springer, 2019)
Iron oxide, in the form of magnetite (MG)–functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous ...
Highly-efficient N-arylation of imidazole catalyzed by Cu(II) complexes with quaternary ammonium-functionalized 2-acetylpyridine acylhydrazone
(Elsevier, 2019)
The reaction of (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium-chloride (HLCl) with copper(II) perchlorate led to mononuclear [CuLCl]ClO4 complex (1). The same reaction with excess ...
Occurrence of hyperalkaline spring water in the Brezanska river, Central Serbia
(International Multidisciplinary Scientific GeoConferences (SGEM), 2019)
Hyperalkaline (pH>10.5) springs are extremely rare. There are only about ten in the entire world. This type of water has been identified in an ultramafic massif in central Serbia, on Mt. Studena, during the course of ...
Influence of A’ cation substitution on promotion of supercapacitance of rare earth/CoO3-based spray pyrolytic perovskite microspheres
(Società Chimica Italiana, 2019)
Considerable promotion of A’ substituted AA’BO3 perovskite-like structure of rare earth–CoO3 composite supercapacitive performances is reported. The influence of cation substitution in perovskite structure on supercapacitance ...
Electrochemical performances of rare earth Co-based mixed oxides and their application as supercapacitors and fuel cells
(International Association of Physical Chemists, 2019)
Perovskite have emerged as promising materials in newly invented energy storage and conversion devices due to their exceptional thermal stability, electronic structure, ionic conductivity, electron mobility, and redox ...
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 ...
The Briggs-Rauscher reaction as an unusual detector for a different type of bronzes
(Institute of Technical Sciences of SASA, 2019)
The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually ...
Examining erosion resistance of ceramics for electrical engineering applications
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITSBeograd : Društvo za obnovljive izvore električne energije, 2019)
Establishing a wind park presents a complex enterprise, which involves numerous activities, often impossible to synchronize and drive into the appropriate time-frame. Therefore, in some cases, based on reasonable suspicion, ...
