Carbon-supported hydrous ruthenium oxide composite as electrochemical supercapacitors - 1. Preparation, Morphology and Characterization of the Composites / Kompozitni materijal hidratisani rutenijum oksid / ugljenik kao elektrohemijski superkondenzator 1. dobijanje, morfologija i karakterizacija 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 ...
Functionalized macroporous copolymer of glycidyl methacrylate: The type of ligand and porosity parameters influence on Cu(II) ion sorption from aqueous solutions / Funkcionalizovani makroporozni kopolimer na bazi glicidilmetakrilata - uticaj liganda i parametara poroznosti na sorpciju Cu(II) jona iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2009)
The removal of heavy metals from hydro-metallurgical and other industries' wastewaters, their safe storage and possible recovery from waste- water streams is one of the greater ecological problems of modern society. ...
Optimization of the active component grinding process and hydrophobization of the obtained powder fire extinguisher / Optimizacija mlevenja aktivne komponente i hidrofobizacija dobijenog sredstva za gašenje požara]
(Beograd : Savez hemijskih inženjera, 2021)
This work presents a grinding process of monoammonium phosphate (MAP) as an active component in a powder fire extinguisher (PFE). The aim was to determine the grinding time for reaching the optimal particle size of MAP ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Sorption of cadmium ions from saline waters onto Fe(III)-zeolite / Sorpcija jona kadmijuma iz slanih voda na Fe(III)-zeolitu
(Serbia : Association of Chemists and Chemical Engineers of Serbia, 2015)
The sorption of Cd2+ from natural seawater, artificial seawater, distilled water and NaCl solution of the same ionic strength as the seawater onto zeolite modified by iron(III) oxide (Fe(III)-zeolite) was investigated. The ...
Crosslinked polyurethanes based on hyperbranched polymers / Umreženi poliuretani na bazi hiperrazgranatih polimera
(Association of Chemical Engineers of Serbia, 2008)
In this paper, two samples of polyurethane (PU) crosslinked with hydroxy -functonal hyperbranched aliphatic polyester of the second pseudo generation were investigated. For the synthesis of these crosslinked PUs two different ...
Modeling the biodiesel production using the wheat straw ash as a catalyst / Pepeo pšenične slame kao katalizator u proizvodnji biodizela
(Belgrade : Association of the Chemical Engineers of Serbia, 2021)
Wheat straw ash (WSA) was investigated as a new catalyst in biodiesel production from sunflower oil. The catalyst was characterized by temperature-programmed decomposition, X-ray powder diffraction, Hg porosimetry, N2 ...
Evaluation of water, sucrose and minerals effective diffusivities during osmotic treatment of pork in sugar beet molasses / Prividni koeficijenti difuzije vode, saharoze i minerala pri osmotskom tretmanu svinjskog mesa u melasi šećerne repe
(Association of Chemical Engineers of Serbia, 2015)
