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 ...
Formation of Disperse Silver Deposits by the Electrodeposition Processes at High Overpotentials
(Esg, Belgrade, 2012)
In this study, electrodeposition of silver from nitrate solution at the high overpotentials was analyzed. Morphologies of silver deposits obtained at the different overpotentials and with the different electrodeposition ...
Improved synthesis and in vitro study of antimicrobial activity of α,β-unsaturated and α-bromo carboxylic acids / Optimizacija sinteze i in vitro proučavanje antimikrobnog dejstva α,β-nezasićenih i α-bromkarboksilnih kiselina
(Serbian Chemical Society, 2012)
A series of α,β-unsaturated and α-bromo carboxylic acids were identified as potent antimicrobial agents. The antimicrobial activity was evaluated using the broth microdilution method. All acids 1-12 exhibited a significant ...
Comparative study of the phenolic composition of seeds from grapes cv cardinal and alphonse lavallee during last month of ripening
(Chiriotti Editori, 2012)
During the last month of ripening, the phenolic composition of seeds from two widely distributed table grapes, cv Cardinal and Alphonse Lavallee, was determined by HPLC/DAD/ESI/MS. Besides, the concentrations of nutrients ...

Malaria is devastating disease and global public health problem, with nearly half world population exposed to risk. Illness is caused by five Plasmodium species, P falciparum, P ovale, P viva; P malaria and P knowlesi, ...
Atomic partial charges for mixed chloroammine chromium(III) complexes fitted to the molecular electrostatic potential
(Elsevier, 2012)
Using the RESP procedure partial atomic charges for six isomers of a series of octahedral complexes [Cr(NH3)(6-x)(Cl)(x)]((3-x)+) (x = 0, 1, 2, 3) were least-square fitted to the molecular electrostatic potential (MEP) ...
Oxidation of hydroxide ions at platinum-modified zeolite electrode / Izvod oksidacija hidroksilnih jona na zeolitu modifikovanom platinom
(Association of Chemical Engineers of Serbia, 2012)
NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy ...
