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 ...
A Comparative LSER Study of the Reactivity of 2-Substituted Cyclohex-1-eneacetic and 2-Substituted Phenylacetic Acids with Diazodiphenylmethane in Various Solvents
(Wiley, Hoboken, 2009)
The rate constants for the reaction of 2-substituted cyclohex-1-eneacetic and 2-substituted phenylacetic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 degrees C. To explain the kinetic ...
Influence of increased temperature on clay fast drying process
(Revista Romana de Materiale/ Romanian Journal of Materials, 2009)
In this paper are presented testing results during process of fast drying at conditions of increased temperature. Three different masonry raw materials were examined using recircular laboratory dryer with air recirculation. ...
Kinetics of hexavalent chromium sorption on amino-functionalized macroporous glycidyl methacrylate copolymer
(Elsevier, Amsterdam, 2009)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and functionalized ...
Biosynthesis of ethyl caproate and other short ethyl esters catalyzed by cutinase in organic solvent
(Elsevier Science Bv, Amsterdam, 2009)
The main objective of this work was to study the enzymatic synthesis of short chain ethyl esters, a group of relevant aroma molecules, by Fusarium solani pisi cutinase in an organic solvent media (iso-octane), and to assess ...
Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part II. Experimental demonstration
(Elsevier, Amsterdam, 2009)
This paper demonstrates an experimental application of the nonlinear frequency response (FR) method extension to determine adsorption isotherms of binary mixtures. This method, based on the analysis of the response of a ...
Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part I. Theoretical analysis
(Elsevier, Amsterdam, 2009)
In this work adsorption equilibria of binary mixtures are quantified analyzing the nonlinear frequency response of a chromatographic column. Local partial derivatives of an isotherm model can be estimated for certain ...

(Korean Fiber Soc, Seoul, 2009)
The aim of this study was to examine the influence of dyeing on antibacterial efficiency of corona activated polyamide and polyester fabrics loaded with colloidal Ag nanoparticles as well as the influence of the presence ...
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 ...
A study of the photocatalytic degradation of metamitron in ZnO water suspensions
(Elsevier, Amsterdam, 2009)
The photocatalytic degradation of the herbicide metamitron in water using ZnO under Osram ULTRA-VITALUX (R) lamp light was studied. The effect of the operational parameters such as initial concentration of catalyst, initial ...
