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 ...
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 ...
Volatile compounds in medlar fruit (Mespilus germanica L.) at two ripening stages / Isparljiva jedinjenja iz ploda mušmule (Mespilus germanica L.) u dve faze zrenja
(Assoc Chemists & Chemical Engineers Of Serbia, Belgrade, 2013)
Medlar is the fruit of Mespilus germanica L. in the family of Rosaceae. The fruit can be eaten only if "bletted" (softened by frost or longer storage). The effect of the maturation stages on the volatile compounds of the ...
Momentum, heat, and mass transfer analogy for vertical hydraulic transport of inert particles / Analogija prenosa količine kretanja, toplote i mase pri vertikalnom hidrauličkom transportu inertnih čestica
(Association of Chemical Engineers of Serbia, 2014)
Wall-to-bed momentum, heat and mass transfer in the vertical liquid-solids flow, as well as in the single phase flow, were studied. The aim of this investigation was to establish the analogy among those phenomena. Also, ...
Porous poly(methylmethacrylate) and poly(methylmethacrylate-co-acrylamide) / Porozni poli(metilmetakrilat) i poli(metilmetakrilat-co-akrilamid)
(Association of Chemical Engineers of Serbia, 2006)
The characteristics of two types of porous polymers: poly(methyl methacrylate) and copolymers of methyl methacrylate and acrylamide were investigated in this study. Poly(methyl methacrylate) was synthesized in suspension, ...
The electrocatalytic properties of carbon supported PtRu/C nanoalloys in oxidation of small organic molecules: Comparison with Pt/C catalyst / Elektrokatalitičke osobine nanočestica legura PtRu/C u oksidaciji malih organskih molekula - poređenje sa katalizatorom Pt/C
(Association of Chemical Engineers of Serbia, 2012)
The electrocatalytic activity of carbon supported PtRu/C catalysts, with different composition, toward the electrooxidation of methanol, CO and formic acid were examined in acid and alkaline solution at ambient temperature ...
Antibiotic production by Streptomyces hygroscopicus CH-7 in medium containing Schiff base complexes / Продукција антибиотика помоћу Streptomyces hygroscopicus CH-7 у хранљивим подлогама са комплексима шифових базa
(Association of the Chemical Engineers of Serbia, 2019)
Influence of a modified media on Hexaene H-85 and Azalomycine B production by Streptomyces hygroscopicus CH-7 was investigated. The amino acid L-tryptophan, as a nitrogen source, was replaced with isatin-3-thiosemicarbazone ...
Inhibiting effect of acetonitrile on oxygen reduction on polycrystalline pt electrode in sodium chloride solution
(Belgrade : Association of the Chemical Engineers of Serbia, 2012)
The oxygen reduction reaction (ORR) was studied on the polycrystalline Pt electrode in 0.1 M NaCl electrolyte containing various amounts of acetonitrile (AcN). The state of the electrode surface was characterized by the ...
Development directions of packaging made from polymer materials / Pravci razvoja ambalaže od polimernih materijala
(Association of Chemical Engineers of Serbia, 2011)
World packaging market achieves turnover of about $620 billion per year with one third of this amount being associated with packaging made from polymer materials. It is expected that this kind of packaging consumption will ...
Characterization of the commercial hyperbranched polyesters / Karakterizacija komercijalnih hiperrazgranatih poliestara
(Association of Chemical Engineers of Serbia, 2010)
In this paper, properties of the commercially available Boltorn® hydroxy-functional aliphatic hyperbranched polyesters of the second, third and fourth pseudo generation, were investigated. Additionally, samples of the third ...
