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 ...
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 ...

(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 lindane sorption from aqueous solution by macroporous copolymer using experimental design
(University of East Sarajevo, Faculty of Technology, 2023)
In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. ...
Microwave assisted synthesis of polyaniline/pullulan (pani/pull) composite
(Society of Physical Chemists of Serbia, 2021)
Microwave assisted synthesis of polyaniline modified by pullulan (PANI/Pull) composite was
performed by aniline oxidation with potassium iodate. The PANI/Pull composite was characterized
using ATR-FTIR technique. FTIR ...
Synthesis and characterization of thin copper coatings obtained by sonoelectrodeposition method
