(Association of the Chemical Engineers of Serbia, 2012)
In this paper, the influence of the catalytic oxidation using water soluble and stable nitroxyl radical 2,2',6,6'-tetramethylpiperidine-1-oxyl (TEMPO) on the structure and properties of cotton fibers was studied. In ...
Utilization of stillages from bioethanol production from various substrates
(Savez hemijskih inženjera, Beograd, 2019)
Stillage is a main by-product of the bioethanol industry and, depending on the origin of substrates for bioethanol production, it can be a significant pollutant affecting the profitability of bioethanol production. Directing ...
Sorption properties of periodate oxidized cotton / Sorpciona svojstva pamuka oksidovanog perjodatom
(Association of the Chemical Engineers of Serbia, 2011)
The effect of periodate oxidation on the chemical and sorption properties of cotton yarn was investigated by determining aldehyde group content, moisture sorption, water retention and iodine sorption. Oxidation of cotton ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...
