The use of biological markers in the determination of the origin and type of organic matter in the sediments of the Tisza River
(Serbian Chemical Soc, Belgrade, 2014)
The objective of this study was to determine the origin and type of organic matter (OM) in recent sediments of the Tisza River, along a distance of 153 km through the territory of Serbia. For this purpose, group ...
Effect of glassy carbon properties on the electrochemical deposition of platinum nano-catalyst and its activity for methanol oxidation / Efekat osobina staklastog ugljenika na elektrohemijski nataložen platinski nano-katalizator i njegovu aktivnost u oksidaciji metanola
(Serbian Chemical Society, 2007)
The effects of the properties of glassy carbon on the deposition of platinum particles and the electrocatalytic activity of platinum supported on glassy carbon (GC/Pt) for methanol oxidation in alkaline and acidic solutions ...
Geochemical investigation as a tool in the determination of the potential hazard for soil contamination (Kremna Basin, Serbia)
(Belgrade : Serbian Chemical Society, 2015)
The geochemical composition of the soils and underlying sediments in the Kremna Basin was investigated. The aim was to assess whether the observed heavy metal concentrations in the soil samples represent geogenic or ...
Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
The Effect of Deposition Process Exchange Current Density on the Thin Metal Film Formation on Inert Substrate / Uticaj gustine struje izmene na proces taloženja tankih filmova metala na nesrodnim podlogama
(Belgrade : Serbian Chemical Society, 1997)
The initial stage of thin surface metal film formation on inert substrate is considered. The simultaneous action of both active centers and nucleation exclusion zones was taken into consideration when discussing the ...
Electrochemical properties of carbonized bentonite / Elektrohemijska svojstva karbonizovanih bentonita
(Serbian Chemical Society, 2022)
Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, ...
Synthesis, antioxidant and antimicrobial activity of carbohydrazones
(Serbian Chemical Society, 2017)
Fourteen mono- and bis-carbohydrazone ligands have been synthesized and characterized. Antioxidant activity of the substances was investigated together with possible (E)/(Z) isomerization, and explained on the most active ...
Supercapacitive properties of the alkali metal hydroxides-activated carbons obtained from sucrose / Суперкапацитативна својства угљеничних материјала добијених из сахарозе и активираних хидроксидима алкалних метала
(Belgrade : Serbian Chemical Society, 2022)
The influence of different hydroxides, applied to activate carbon black, on the electrochemical properties of activated carbon was investigated. The carbon material was prepared by hydrothermal treatment of sucrose and ...
Electrochemical stability of metformin in NaHCO3 and Na2SO4 water solution at Au, GC and IrOx electrodes / Електрохемијска стабилност метформина у воденим растворима NaHCO3 И Na2SO4 на Au, GC и IrOx електродама
(Serbian Chemical Society, 2019)
In this study the electrochemical behavior of metformin (MET), oral antihyperglycaemic agent, was assayed at three different electrodes. The drug standard was investigated by cyclic voltammetry (CV) and square wave ...
Thermal solid-state Z/E isomerization of 2-alkylidene-4-oxothiazolidines: Effects of non-covalent interactions / Termalna Z/E izomerizacija 2-alkiliden-4-oksotiazolidina u čvrstom stanju - uticaj nekovalentnih interakcija
(Serbian Chemical Soc, Belgrade, 2011)
Configurational isomerization of stereo-defined 5-substituted and unsubstituted 2-alkylidene-4-oxothiazolidines (1) in the solid state, giving the Z/E mixtures in various ratios, was investigated by 1H-NMR spectroscopy, ...
