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 ...
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 ...
Electrical Conductivity of Lignocellulose Composites Loaded with Electrodeposited Copper Powders
(Esg, Belgrade, 2011)
Composites based on polymers with conductive fillers have been gaining more and more significant roles in a variety of technological domains and are in the research focus of numerous studies as a part of growing research ...
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 ...
Supercapacitors based on graphene/pseudocapacitive materials
(Serbian Chemical Society, 2017)
Composites of graphene and SnO2 were successfully prepared by a single step simultaneous synthesis of SnO2 and reduction of graphene oxide (GO). Three different compositions of precursor solution resulted in different ...
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 ...
Electrical Conductivity of Lignocellulose Composites Loaded with Electrodeposited Copper Powders. Part III. Influence of Particle Morphology on Appearance of Electrical Conductive Layers
(Esg, Belgrade, 2012)
The electrical conductivity of the system based on lignocellulose (LC) biopolymer matrix filled with electrodeposited copper powder has been studied. Galvanostatically produced copper powder, having highly porous, highly ...
The shape of the polarization curve and diagnostic criteria for control of the metal electrodeposition process
(Serbian Chemical Society, 2016)
The simulated shapes of the polarization curves were correlated with the type of metal electrodeposition process control as a function of the ratio of the exchange current density to the limiting diffusion current density ...
Study on the morphology and thermomechanical properties of poly(urethane-siloxane) networks based on hyperbranched polyester / Proučavanje morfologije i termomehaničkih svojstava umreženih poli(uretan-siloksana) na bazi hiperrazgranatog poliestra
(Association of Chemical Engineers of Serbia, 2013)
Two series of polyurethane films based on hyperbranched polyester of the second pseudo-generation (Boltorn®), 4,4'-methylenediphenyl diisocyanate and two different siloxane prepolymers, α,ω-dihydroxy-(ethylene oxide-poly ...
Characterization and Morphology of Copper Powder Particles as a Function of Different Electrolytic Regimes
(Esg, Belgrade, 2010)
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The results obtained in constant regimes were compared with those obtained in ...
