Catalytic wet peroxide oxidation of tartrazine on Al,Fe-pillared clays – kinetic study
(Association Internationale pour l'Etude des Argiles - AIPEABrasilian Geochemical Society - SBGq, 2013)
Smectite rich clay from Bogovina (Serbia) was used for the synthesis of a series of Al,Fe-pillared clays (PILCs) with different Fe3+ content. The obtained PILCs were characterized and tested in the catalytic wet peroxide ...
Study on preparation and properties of novel functionalized polyester copolymers based on siloxanes
(Belgrade : Serbian Chemical Society, 2013)
Novel functionalized macroporous copolymers were synthesized by reaction of the
pendant epoxy groups of poly(glycidyl methacrylate)-co-poly(ethylene glycol dimethacrylate)s with 1,3-bis(3-aminopropyl)tetramethyldisiloxane ...
Energetics of the steps in proton pumping mechanism and preventing of backflow reactions in cytochrome c oxidase
(Serbian Chemical Society, 2013)
Cytochrome c oxidase (CcO) is the terminal enzyme of aerobic respiration, which is responsible for processing most of the biological oxygen and generating electrochemical proton gradient in aerobic cells [1]. The energy ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
Kinetics of copper adsorption from wastewater by lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is ...
Adsorption isotherms of removing copper from aqueous solutions by low cost adsorbent-lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Serbian lignite from ’’Kolubara’’ deposit was used as a low cost adsorbent for removal of copper ions (Cu2+) from aqueous solutions. Lignite was subjected to the elementary and technical analysis as well as BET and FTIR ...
Nondestructive evaluation of degradation level for refractory and polymer composite materials in extreme conditions
(Institute for Multidisciplinary Research, 2013)
Non-destructive evaluation of degradation level in extreme condition caused by: thermal shock and cavitation erosion for refractory concrete (LCC) and durability of sulfur concrete in aggressive environment were goal of ...
Concentration method for the mining wastewater-valorization of the copper
(The Regional Environmental Center for Central and Eastern Europe, 2013)
During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative ...
In vitro antitumor actions of extracts from endemic plant Helichrysum zivojinii
(Biomed Central Ltd, London, 2013)
Background: The aim of this research was to determine the intensity and mechanisms of the cytotoxic actions of five extracts isolated from the endemic plant species Helichrysum zivojinii Cernjavski & Soska (family Asteraceae) ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...
