Modified bentonite as adsorbent and catalyst for purification of wastewaters containing dyes / Modifikovani bentonit kao adsorbent i katalizator za prečišćavanje otpadnih voda koje sadrže boje
(Assoc Chemists & Chemical Engineers Of Serbia, Belgrade, 2010)
Modification and characterization of bentonite from location Bogovina, Serbia was performed in order to obtain material applicable in wastewater purification. The LT 75μm bentonite fraction was used in organobentonite ...
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 ...
Performances of continuous dryer with inert medium fluidized bed / Performanse kontinualne sušnice sa fluidizovanim slojem inertnih čestica
(Association of Chemical Engineers of Serbia, 2008)
A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and ...
Absorption in a three-phase fluidized bed II: Mass transfer investigations / Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
(Association of Chemical Engineers of Serbia, 2003)
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration ...
Electrochemical supercapacitors: Operation, components and materials
(Association of Chemical Engineers of Serbia, 2018)
Supercapacitors are the best choice when there is a need to deliver high power to the consumer or to store energy. Hybrid supercapacitors with their beneficial characteristics can somewhat overcome the basic lack of ...
Development directions of packaging made from polymer materials / Pravci razvoja ambalaže od polimernih materijala

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 ...
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 ...
Economizer water-wall damages initiated by feedwater impurities
(Association of Chemical Engineers of Serbia, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
The impact of isatin derivatives on antibiotic production by Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2016)
The effect of isatin derivatives as a nitrogen source on antibiotic (hexaene H-85 and azalomycine B) production by Streptomyces hygroscopicus CH-7 was studied. Isatin-3-hydrazone, 5-chloroisatin-3-hydrazone, isatin-3-tos ...
