Spin states of Mn(II) and Fe(III) complexes with thiosemicarbazone
(Viena, Austria : Institute of Applied Synthetic Chemistry, TU WienChemIT e.U., 2023)
Mn(II) and Fe(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole have been synthesized and characterized by single-crystal X-ray diffraction. Two complexes have the same ligand system – bis ...
The pseudo-capacitance of hydrous RuO2 accompanied by mass changes
(Crnogorsko društvo za koroziju, zaštitu materijala i zaštitu životne sredine, 2023)
Pseudocapacive reaction of ruthenium oxide was investigated by cyclic voltammetry (CV) measurements combined with electrochemical quartz-crystal nanobalance. RuO2 was synthesized by one-pot microwave assisted hydrothermal ...
Electrochemical testing of iron phosphor tungsten bronzes as potential electrode material
(Serbian Ceramic Society, 2023)
In this work, synthesized 12-tungstenphosphoric acid (H3PW12O40 ∙ nH2O, PWA) was further
ionically exchanged with Fe3+ ions, which led to the formation of the FePWA salt (FePW12O40 x nH2O). FePWA was then subjected to ...
Fabrication of cobalt oxide supported carbon paste electrode for sensitive and selective Levofloxacin sensing
(Division of Analytical Chemistry of the European Chemical Society, 2023)
In this study, a modified cobalt oxide (Co3O4) carbon paste electrode was prepared for the detection of Levofloxacin. Co3O4 nanoparticles were synthesized by the chemical coprecipitation method. The electrochemical properties ...
Fabrication of bismuth-oxychloride supported carbon paste electrode for sensitive and selective Quinine sensing
(University of Belgrade - Faculty of Chemistry, 2023)
In this work, a modified bismuth-oxychloride (BiOCl) carbon paste electrode was prepared for the
detection of quinine. BiOCl nanoparticles were synthesized by the chemical coprecipitation method. The electrochemical ...
Electrochemical determination of nitrite in water samples using carbon paste electrode modified with Ni/Bi oxide / Elektrohemijsko određivanje nitrita u uzorcima vode primenom elektrode od ugljenične paste modifikovane Ni/Bi oksidom
(Belgrade : Serbian Chemical Society, 2023)
U ovom istraživanju, sintetisani su kompozitni nanomaterijali koji su korišćeni za modifikaciju elektrode od ugljenične paste. Materijali su sintetisani metodom koprecipitacije, a korišćene su soli nikla i bizmuta. Morfološke ...
What could be the reason for different behavior of phosphate tungsten and phosphate molybdenum bronzes in Briggs-Rauscher reaction: New insight
(Beograd : Institut za multidisciplinarna istraživanja, 2022)
Recently, two different effects of phosphate tungsten (PWB) and phosphate molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble ...
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 ...
Crystallographic investigation of the iron phosphate tungsten bronze (Fe-PWB)
(Institut za multidisciplinarna istraživanja, 2023)
In this paper, 12-tungstenphosphoric acid (PWA) was synthesized in combination with FeCl3 at room temperature (25 oC). At such manner, Fe3+ ion exchange gave new 12-tungstenphosphoric salt of the transition metal iron ...
Synthesis of new praseodymium doped phosphate tungsten bronze
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2022)
For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
(PWA) [1]. PWA was first converted into H3PW12O40×6H2O ...
