Microwave-assisted immobilization of lipase from Candida rugosa on Eupergit (R) supports
(Wiley, Hoboken, 2009)
BACKGROUND: Immobilization of lipase (triacylglycerol acylhydrolase EC 3.1.1.3) from Candida rugosa on Eupergite (R) C and Eupergit (R) C 250L was performed under microwave irradiation in order to reduce immobilization ...
Silver-Loaded Cotton/Polyester Fabric Modified by Dielectric Barrier Discharge Treatment
(Wiley-VCH Verlag Gmbh, Weinheim, 2009)
The preparation of antimicrobial silver-loaded cotton/polyester fabrics has been carried out by DBD surface activation followed by silver sorption from aqueous silver nitrate solution. A series of DBD fabric treatments was ...
Electrochemical polymerization and initial corrosion properties of polyaniline-benzoate film on aluminum
(Elsevier Science Sa, Lausanne, 2009)
Electrochemical synthesis of polyaniline (PANI) on aluminum electrode from aqueous Solution Of 0.25 mol dm(-3) aniline and 0.2 mol dm(-3) sodium benzoate has been investigated under potentiodynamic and galvanostatic ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Elsevier Sci Ltd, Oxford, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
Characterization of sepiolite by inverse gas chromatography at infinite and finite surface coverage
(Elsevier Science Bv, Amsterdam, 2009)
The adsorption properties of sepiolite from Andrici, Serbia, were studied by inverse gas chromatography at zero and finite surface coverage between 483 and 513 K. The thermodynamic parameters (free energy, enthalpy, entropy) ...
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 ...
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 ...
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 ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
Solids flow pattern in gas-flowing solids-fixed bed contactors. Part I Experimental
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
An experimental investigation of the solids flow pattern in gas-flowing solids-fixed bed contactors is presented. The apparatus and procedures for determining the dynamic and static solids holdups, solids residence time ...
