A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve
(4th FEZA CONFERENCE Collège de France PARIS, 2008)
An efficient removal of the organic component from the as-synthesized solid in order to access the
internal free space is an important step in the final preparation of the porous materials. Recently, kinetic studies of ...
The Antimicrobial Efficiency of Cotton and Polyester Fabrics Loaded with Silver Nanoparticles
(2nd International Scientific Conference Textiles of the Future, 13-14 November, 2008, Kortrijk, Belgium, 2008)
In this study, antimicrobial efficiency and its laundering durability on cotton and polyester fabrics loaded with colloidal Ag nanoparticles was evaluated. The influence of the presence of Ag nanoparticles on the color ...
Crystal structure of picotpaulite, TlFe2S3, from Allchar, FYR Macedonia
(Slovenian Chemical Society, 2008)
The crystal structure of the mineral picotpaulite, TlFe2S 3, was solved and refined using single-crystal X-ray diffraction data collected at room temperature. The symmetry is orthorhombic, space group Cmcm, with unit-cell ...
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 ...
Investigation of mechanism and kinetics of chalcopyrite concentrate oxidation process
(Croatian Metallurgical Society, 2008)
The oxidation process of chalcopyrite concentrate "Rudnik" (Serbia) was investigated by DTA-TG measurements under air conditions in the temperature range of 298 - 1173 K, as well as by XRD analysis of the oxidation products ...
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 ...
