Determination of ionization constants of selected monocarbohydrazone derivatives
(Academy of Sciences and Arts of the Republic of Srpska, 2020)
Carbohydrazone derivatives represent a very significant class of compounds due to their wide biological activity. Ionization states of functional groups present in the molecule are of vital importance for understanding of ...
Optimization of electrodeposition parameters to improve composite hardness of nickel coatings on brass substrate for varying film thicknesses and applied indentation loads
(Belgrade : ETRAN Society, 2022)
In this investigation, nickel coatings were electrodeposited on brass substrate. The effects of
electrodeposition process parameters such as, current density and deposition time (coatings thickness), on surface morphology ...
Amino functionalized graphene quantum dots - new fluorescent sensor for Co2+ ions
(Szeged, Hungary : University of Szeged, 2021)
Graphene quantum dots (GQDs) were fabricated by simple electrochemical oxidation of
graphite electrodes. Modified GQDs were obtained by gamma irradiation of GQDs, EDA, and
IPA mixture at a dose of 25 kGy. In this ...
Nanoscale topography of GC/Pt-C and GC/Pt-Ru-C electrodes studied by means of STM, AFM and XRD methods
(Materials Science Forum, 2006)
Electrodes, assigned as GC/Pt-C and GC/Pt-Ru-C, were formed by deposition of Pt-based catalysts (47.5 wt % Pt + high surface area carbon) and (54 wt. % Pt-Ru alloy + high surface area carbon) on glassy carbon (GC) discs. ...
Effect of concentration pigment particles on microstructure of the metal matrix copper composite coatings
(Belgrade : Serbian Academy of Sciences and ArtsBelgrade : Faculty of Technology and Metallurgy, University of Belgrade, 2022)
This research focuses on the synthesis and characterization of composite coatings via electrochemical route with co-deposition pigments. For that reason, the effect of adding yellow green phosphorescent pigment on ...
Synthesis and characterization of thin copper coatings obtained by sonoelectrodeposition method
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
Influence of an intensity of ultrasonic mixing of electrolyte in a temperature range of 27–37 °C and ultrasonic power intensity in the range of 3.77–18.84 W/cm2 (10–50 %) on a synthesis of fine-grained copper deposits was ...
Molecular and isotope composition of biomarkers in immature oil shale and its liquid pyrolysis products (open and closed system)
(European Association of Geoscientists & Engineers, 2021)
The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open ...
Morphology, structure and hardness of electrolytically produced copper coatings
(2022)
Poster presented at: 4th International Congress of Chemists and Chemical Engineers of Bosnia and Herzegovina, June, 30th-July, 02nd, Sarajevo, Bosnia and Herzegovina
pH-Dependent solubility profiles of imipramine and amitriptyline hydrochlorides
(International Association of Physical Chemists, 2019)
The aim of this study was to examine solubility-pH behavior of desipramine structural analogues:
imipramine and amitriptyline hydrochlorides. Appearance of aggregates (trimer, around pH 4 in imipramine case), which lead ...
