Covalent immobilisation of invertase onto a reactive film composed of 2-hydroxyethyl methacrylate and glycidyl methacrylate: properties and application in a continuous flow system
(Elsevier Science Sa, 2003)
Invertase was covalently immobilised on the poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-GMA)) film. The invertase immobilisation capacity of the films was increased as the GMA ratio increased in the ...
Fixed point of multivalued mapping in uniform spaces
(Indian Academy Sciences, 2003)
In this paper we prove some new fixed point theorems for multivalued mappings on orbitally complete uniform spaces.
Uranium recovery by immobilized and dried powdered biomass: characterization and comparison
(Elsevier Science Bv, 2003)
Immobilized and dried powdered Trametes versicolor and Phanerochaete chrysosporium basidio of spores were used for the recovery of uranium from aqueous solutions. The biosorption of UO22+ ions by the carboxymethylcellulose ...
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)
An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
Poly(2-hydroxyethylmethacrylate)/chitosan dye and different metal-ion-immobilized interpenetrating network membranes: Preparation and application in metal affinity chromatography
(John Wiley & Sons Inc, 2003)
Composite membranes were synthesized with 2-hydroxyethylmethacrylate and chitosan (pHEMA/chitosan) via an ultraviolet-initiated photopolymerization technique in the presence of an initiator (alpha,alpha'-azobisisobutyronitrile). ...
Affinity dye-ligand poly(hydroxyethyl methacrylate)/chitosan composite membrane for adsorption lysozyme and kinetic properties
(Elsevier Science Sa, 2003)
A composite membrane from 2-hydroxyethyl methacrylate (HEMA) and poly(hydroxyethyl methacrylate)/chitosan (pHEMA/chitosan) was synthesized via UV initiated photo-polymerization in the presence of an initiator alpha,alpha ...
Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
The energy distribution of the interface state density of Pb/p-Si Schottky contacts exposed to clean room air
(Elsevier Science Bv, 2003)
Pb/p-Si Schottky barrier diodes (SBDs) with and without thin native oxide layer have been fabricated. The previously polished p-Si wafer has been cleaned by using a traditional RCA clean with the final dip in diluted HF ...
Fundamental and high-order harmonic susceptibilities of a BSCCO(2223) bulk superconductor
(Elsevier Science Bv, 2003)
Measurements of fundamental and high-order harmonic susceptibilities, chi(n), = chi(n)' + ichi(n)" (n = 1, 2, 3, 5 and 7), were made on a cylindrical BSCCO(2223) bulk sample in the range 15-120 K at fields ranging from 8 ...
Synthesis and crystal structure of bis[N-(2-fluoro-3-methoxy)-salicylideneaminato]copper(II)
(Kluwer Academic/Plenum Publ, 2003)
The title compound, bis[N-(2-fluoro-3-methoxy)-salicylideneaminato] copper(II) [Cu(C14H12O2FN)(2)] was synthesized and its crystal structure was determined. The title compound is triclinic, space group P (1) over bar with ...
