Selected trace element concentrations in ambient air and in horse chestnut leaves in Belgrade / Koncentracije odabranih elemenata u tragovima u vazduhu i u listovima divljeg kestena u Beogradu
(Association of the Chemical Engineers of Serbia, 2015)
In this study, airborne particulates (PM10) and leaves of horse chestnut were collected at selected urban sites in Belgrade, Serbia, in years 2006, 2009 and 2012. All samples were analysed for trace element concentrations ...
Continuous improvement concepts as a link between quality assurance and implementation of cleaner production - case study in the generic pharmaceutical industry
(Savez hemijskih inženjera, Beograd, 2016)
The subject and the research objective presented in this article is establishing of the relationship between quality assurance and implementation of cleaner production in the generic pharmaceutical industry through the ...
Amoxicillin photodegradation by nanocrystalline tio2
(Savez hemijskih inženjera, Beograd, 2017)
Nanocrystalline TiO2, synthesized by sol-gel route and characterized by XRPD, BET and SEM measurements, was applied in the photocatalytic degradation of amoxicillin, using an Osram Ultra-Vitalux (R) lamp as the light source. ...
Heterogeneous kinetics of vegetable oil transesterification at high temperature
(Savez hemijskih inženjera, Beograd, 2016)
Currently, the catalytic efficiency and reusability of the solid base catalysts cannot meet the demand of industrial biodiesel production under low temperature. The purpose of this study is to define the kinetics of ...
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 ...
The bioethanol production with the thin stillage recirculation
(Association of the Chemical Engineers of Serbia, 2009)
In this paper, the bioethanol production with the thin stillage recirculation in mashing was investigated. The mashing was performed with recirculation of: 0, 10, 20 and 30% of the thin stillage. The thin stillage recirculation ...
Progress in the production of bioethanol on starch-based feedstocks
(Association of the Chemical Engineers of Serbia, 2009)
Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic materials, is one of the alternative energy resources, which is both renewable and environmentally friendly. Although, the priority in ...
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 ...
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 ...
Influence of compression speed and deformation percentage on mechanical properties of calcium alginate particles / Uticaj brzine kompresije i procenta deformacije na mehaničke karakteristike kalcijum alginatnih čestica
(Association of the Chemical Engineers of Serbia, 2015)
Hydrogel particles are often used as carriers for the immobilization of enzymes, polyphenolic antioxidants, whole microbial, plant or mammalian cells. In many processes, the mechanical properties of alginate particles are ...
