Kinetics of sintering of polyethilene glycol and lanthanum doped aluminum oxide obtained by the sol-gel method / Uticaj dodatka polietilen-glikola i lantana na mehanizam sinterovanja aluminijum-oksida dobijenog sol-gel postupkom
(Association of Chemical Engineers of Serbia, 2011)
Sintering and crystallization of low-density polyethylene glycol (PEG) and lanthanum, La(III)-doped Al2O3 aerogels prepared from aluminum isopropoxide were investigated. The sintering behavior of non-doped and doped aerogels ...
Carbon-supported hydrous ruthenium oxide composite as electrochemical supercapacitors. 3 - Capacitive Properties of the Composites / Kompozitni materijal hidratisani rutenijum oksid / ugljenik kao elektrohemijski superkondenzator 3. Kapacitivna svojstva kompozita
(Association of Chemical Engineers of Serbia, 2007)
Preparation of hydrous ruthenium oxide/carbon black nanocomposite material was performed by the impregnation method starting from hydrous RuO2 sol as a precursor. Black Pearls 2000 (R) (BP) and Vulcan (R) XC-72 R (XC) was ...
Whether integrating refining and petrochemical business can provide opportunities for development of petrochemical industry in Serbia / Da li integrisanje rafinerijskog i petrohemijskog biznisa pruža mogućnost za razvoj petrohemijske industrije u Srbiji
(Serbia : Association of Chemists and Chemical Engineers of Serbia, 2016)
Since the beginning of 90s of last century both the petroleum industry and petrochemical industry have operated in difficult circumstances. In particularly, margins of petroleum and petrochemical industry were exacerbated ...
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 ...
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 ...
