Investigation of the morphology and surface properties of crosslinked poly(urethane-ester-siloxane)s / Ispitivanje morfologije i površinskih svojstava umreženih poli(uretan-estar-siloksana)
(Association of Chemical Engineers of Serbia, 2012)
Two series of crosslinked poly(urethane-ester-siloxane)s were synthesized from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS- -EO), 4,4'-methylenediphenyl diisocyanate and Boltorn® hyperbranched ...
Effect of the electrolysis regime on the structural characteristics of honeycomb-like electrodes
(Soc Chemists Technologists Madeconia, Skopje, 2013)
The effect of different current regimes of electrolysis on the micro- and nanostructural characteristics of open porous structures was examined by the analysis of honeycomb-like copper electrodes obtained by constant ...
The Effect of Periodically Changing Regimes on the Electrodeposition of Silver Powder
(Esg, Belgrade, 2011)
The effect of different deposition regimes (constant and reversing currents, constant and pulsating overpotential), on the powdered and dendritic silver electrodeposits morphology were investigated. The morphology of ...
Electrodeposition of Fe Powder from Citrate Containing Electrolytes
(Esg, Belgrade, 2010)
Polarization characteristics of the electrodeposition processes of Fe powders from different citrate electrolytes and the morphology of the obtained powders were investigated. The effect of complexing agents on the cathodic ...

Preparation and characterization of poly(Urethane-siloxane)/titanium-dioxide nanocomposites
(Belgrade : Association of the Chemical Engineers of Serbia, 2019)
This work is focused on preparation of poly(urethane-siloxane)/titanium-dioxide nanocomposites (PUSNs) with enhanced features. PUSNs were prepared by the in situ polymerization reaction using titanium-dioxide as a nano-filler ...
The use of salicylaldehyde derivatives as a nitrogen source for antibiotic production by Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2017)
In the present work, four derivatives of salicylaldehyde (salicylaldehyde-hydrazone, phenylhydrazone, semicarbazone and thiosemicarbazone) were synthesized using both conventional (95% ethanol) and green (crude glycerol ...
