Adsorption of mycotoxins by organozeolites
(Elsevier, Amsterdam, 2005)
Adsorption of zearalenone (ZEN), ochratoxin A (OCHRA) and aflatoxin B1 (AFB1) on natural zeolite, clinoptilolite, modified with different amounts of octadecyldimethylbenzyl ammonium (ODMBA) ions was investigated. Results ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
Kinetics of specific surface area change using the Boltzmann model
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Sinterovanjem sistema 2MgO·2Al2O3·5SiO2, dobija se kordijerit, koji zbog svojih svojstava predstavlja izuzetno atraktivan keramički materijal. U cilju ispitivanja mogućnosti sniženja temperature formiranja kordijerita tokom ...
The adsorption of sulphate, hydrogenchromate and dihydrogenphosphate anions on surfactant-modified clinoptilolite
(Elsevier Science Bv, Amsterdam, 2000)
The adsorption of sulphate, hydrogenchromate and dihydrogenphosphate anions on surfactant-modified clinoptilolite (SMC) was investigated. The SMCs were prepared by the adsorption of cis-1-aminoctadecen-9 (oleylamine) on ...
Adsorption of ochratoxin A on octadecyldimethyl benzyl ammonium exchanged-clinoptilolite-heulandite tuff
(Elsevier, Amsterdam, 2003)
The in vitro adsorption of ochratoxin A (OCHRA) by clinoptilolite-heulandite rich tuff modified with different amounts -20, 50 and 100 mumol M+/g of octadecyldimethyl benzyl ammonium (ODMBA) ion was investigated. The ...
Chemical-technological processing of the complex barite-sulphide ore
(Blackwell Munksgaard, Copenhagen, 2003)
The investigation results of the processing possibilities of the complex barite-sulphide ore from "Bobija" deposit (Serbia) for the sake of lead, zinc and copper extraction are presented in this paper. Through x-ray ...
Another look at the molecular mechanism of the resistance of H5N1 influenza A virus neuraminidase (NA) to oseltamivir (OTV)
(Elsevier Science Bv, Amsterdam, 2008)
In the context of a recent pandemic threat by the worldwide spread of H5N1 avian influenza, the high resistance of H5N1 virus to the most widely used commercial drug, oseltarnivir (Tamiflu), is currently an important ...
Application of different collectors in the flotation concentration of feldspar, mica and quartz sand
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The potential application of different cation collectors in the flotation concentration of mica, feldspar and quartz sand has been investigated. Raw materials (Bujanovac and Ub) from two localities in Serbia were used. The ...
Hydration of mechanically activated mixtures of Portland cement and fly ash
(University of Chemistry and Technology, Prague, 2007)
Fly ash (FA) can be used in cement mixtures with certain limitations. For experimental purposes, mixtures of Portland cement (PC) and FA were used. The content of FA in the mixtures was either 30% or 50%. The mechanical ...
Surface properties of natural calcite filler treated with stearic acid
(University of Chemistry and Technology, Prague, 2009)
In order to obtain hydrophobic material, the water suspension of natural limestone with the high content of calcite (>95%), was treated with different amounts (0.5-4%) of stearic acid dissolved in chloroform. Thermal ...
