Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Elsevier Science Sa, Lausanne, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm(-2) from aqueous solution of 1.0 mol dm(-3) HCl and 0.25 mol dm(-3) aniline monomer. ...
Acid-formed pectin gel delays major incomplete kiwi fruit allergen Act c 1 proteolysis in in vitro gastrointestinal digestion
(John Wiley & Sons Ltd, Chichester, 2009)
BACKGROUND: It is thought that food sensitisers must be able to reach the intestine in order to sensitise patients. Pectin is a gel-forming plant polysaccharide that can protect allergens from in vivo gastric digestion and ...
Lipases and proteases produced by indigenous Pseudomonas aeruginosa strain as potential detergent additives / Lipaze i proteaze dobijene iz ekstremofilne Pseudomonas aeruginosa vrste kao aditivi u formulacijama deterdženata
(Association of Chemical Engineers of Serbia, 2009)
Enzymes produced by indigenous Pseudomonas aeruginosa strain have been subjected to research considering their potential application as detergent additives. As previously noted, lipase produced by Pseudomonas aeruginosa ...
Mass transfer in vertical liquid-solids flow of coarse particles
(Elsevier Science Bv, Amsterdam, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
A mass transfer heterogeneous in systems by the adsorption method
(Association of the Chemical Engineers of Serbia, 2009)
A mass transfer coefficient between: A liquid and single sphere and a liquid And a column wall in packed and fluidized beds of a spherical inert Particle have been studied experimentally using the adsorption method. The ...
Synthesis and characterization of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels
(Springer, New York, 2009)
In the present study poly(2-hydroxyethyl methacrylate-co-itaconic acid) (P(HEMA/IA)) hydrogels were synthesized by free-radical copolymerization of 2-hydroxyethyl methacrylate and itaconic acid in order to evaluate as ...
The effect of Y2O3 addition on thermal shock behavior of magnesium aluminate spinel
(International Institute for the Science of Sintering, Beograd, 2009)
The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the modified glycine nitrate procedure (MGNP). ...
Thermal properties of PS/TiO2 nanocomposites obtained by in situ bulk radical polymerization of styrene
(Elsevier Science Bv, Amsterdam, 2009)
TiO2 nanoparticles. surface modified with 6-palmitate ascorbic acid, were incorporated in polystyrene (PS) by in situ bulk radical polymerization of styrene using 2,2'-azobisisobutyronitrile as initiator. The molar mass ...
Immobilization of modified penicillin G acylase on Sepabeads carriers
(Versita, Warsaw, 2009)
An approach to stable covalent immobilization of chemically modified penicillin G acylase from Escherichia coli on Sepabeads(R) carriers with high retention of hydrolytic activity and thermal stability is presented. The ...
Processing of dense nanostructured HAP ceramics by sintering and hot pressing
(Elsevier Sci Ltd, Oxford, 2009)
A nanosized HAP powder was sintered and hot pressed, in order to obtain dense HAP ceramics. In a first series of experiments, the powder was isostatically pressed into uniform green compacts and sintered at temperatures ...
