The ways to improve the economy of bioethanol production in Serbia
(24th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems, ECOS 2011, 2011)
The rapid depletion of the world fossil fuel supply and the increasing problem of greenhouse gas effects have strenghtened the worldwide interest in alternative sources of energy. Bioethanol accounts for the majority of ...
Surface composition and adsorption properties of activated carbon cloth
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Surface properties of activated carbons have shown to play an important role in
adsorption process. The presence of various functional groups (such as phenolic, carbonyl,
carboxylic) on the carbon surface depends on the ...
Sugar beet pulp and molasses as a solid state fermentation media for cellulase production by Paenibacillus chitinolyticus CKS1
(Bor : Technical Faculty, 2015)
Sugar beet pulp (SBP) and molasses, by-products from sugar industry were used as a substrate for cellulase production in this study. Solid state fermentation (SSF) was performed by a natural isolate Paenibacillus chitinolyticus ...
EFFECT OF GALACTO-OLIGOSACCHARIDES ON STAPHYLOCOCCUS EPIDERMIDIS GROWTH AND EXAMINATION OF THEIR DIFFUSION FROM COSMETIC FORMULATIONS
(Faculty of Technology, University of East Sarajevo, 2021)
According to the current definition, a prebiotic is described as “a substrate that is selectively utilized by host microorganisms conferring a health benefit”. Originally, the concept of prebiotics was defined for the gut ...
Cellulolytic potencial of a strain Paenibacillus sp. isolated from soil
(Serbian Chemical Society, 2013)
Cellulases are the enzymes which cause hydrolyzis of the polysaccharide cellulose into
smaller sugar units. Bacterial cellulases possess more advantages when compared to the
cellulases from other sources. The gram positive, ...
Multifunkcionalna svojstva pamuka oksidisanog kalijum-permanganatom / Multifunctional properties of cotton oxidized with potassium permanganate
(Požarevac : Društvo hemičara, tehnologa i metalurga, 2017)
U ovom radu pamučna pređa je oksidisana kalijum-pemanganatom (KMnO4) pri različitim pH vrednostima i različitim koncentracijama na sobnoj temperaturi. Oksidacija je vršena u cilju čišćenja pamučnih vlakana i uvođenja ...
Chemical modification of Purolite A109 for application in lipase immobilization
(8th International Conference of the Chemical Societies of the South-East European Countries, Belgrade, Serbia, 2013)
Modern industry recognizes enzymes as important catalysts for batch production of food,
drugs and cosmetics. Because of their price and poor technical characteristics in free form,
enzymes are mostly used as immobilized ...
Naslojavanje TEMPO oksidisanim celuloznim nanofibrilima kao novi pred-tretman za poboljšanje antibakterijskih svojstava viskozne tkanine / Coating with TEMPO oxidized cellulose nanofibrils as novel pre-treatment for improving antibacterial properties of viscose fabric functionalized with chitosan
(Beograd : Srpsko hemijsko društvo, 2019)
The main objective of this study was to obtain viscose fabric
functionalized by chitosan with improved antibacterial properties. In
order to improve interactions between viscose fabric and chitosan, viscose
fabric was ...
Particle-induced x-ray emission spectrometry of size-fractionated atmospheric aerosols
(4th International Yugoslav Nuclear Society Conference - YUNSC, 2002)
Atmospheric aerosol samples were collected with a stacked filter unit (SFU), which
separates the aerosol into a coarse (2-10 µm aerodynamic diameter (AD)) and a fine (< 2
µm AD) size fraction. The samples were analysed ...
Nanokompoziti TiO2/PPy za primenu u fotokatalizi / TiO2/PPy nanocomposites for photocatalytic application
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2023)
Titan(IV)-oksid je jedan od najčešće korišćenih fotokatalizatora, dok za polipirol (PPy) postoje potvrde da je pogodan za ovu primenu. Cilj ovog rada bio je dobijanje kompozita TiO2/PPy sa boljom fotokatalitičkom aktivnosti ...
