Superconducting and Vickers hardness properties of ZnO-added YBCO polycrystalline superconductors
(Wiley-V C H Verlag Gmbh, 2004)
The effects of ZnO addition on the microstructure and mechanical properties of the YBCO have been investigated through XRD, SEM, EDX, ac susceptibility measurements and the standard Vickers micro-hardness testing method. ...
Preparation and characterisation of surfaces properties of poly(hydroxyethylmethacrylate-co-methacrylolyamido-histidine) membranes: application for purification of human immunoglobulin G
(Elsevier, 2004)
In this study, an affinity membrane containing L-histidine as an amino acid ligand was used in separation and purification of human immunoglobulin G (HIgG) from solution and human serum. The polarities and the surface free ...
Biosorption of Hg2+, Cd2+, and Zn2+ by Ca-alginate and immobilized wood-rotting fungus Funalia trogii
(Elsevier, 2004)
Funalia trogii biomass was immobilized in Ca-alginate gel beads. The live and beat inactivated immobilized forms were used for the biosorption of Hg2+, Cd2+ and Zn2+ ions by using plain Ca-alginate gel beads as a control ...
Polyethyleneimine-grafted poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible glucose oxidase immobilization
(Elsevier Science Sa, 2004)
Glucose oxidase (GOD) was immobilized onto polyethyleneimide (PEI) grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-co-GMA)) membranes. The maximum GOD immobilization capacities of the ...
Surface properties of Reactive Yellow 2 immobilised pHEMA and HEMA/chitosan membranes: characterisation of their selectivity to different proteins
(Elsevier, 2004)
Poly(hydroxyethyl methacrylate), pHEMA, and a composite pHEMA/chitosan networks were synthesized in the membrane form via UV initiated photo-polymerisation in the presence of an initiator alpha,alpha'-azoisobutyronitrile. ...
Electrochemical polymerization of 4-allyl-1,2-dimethoxybenzene
(Elsevier Science Bv, 2004)
Redox behaviour of 4-allyl-1,2-dimethoxybenzene (DMAB) was studied by using cyclic voltammetry and electro-chemical polymerization was conducted at the measured peak potential. Constant potential electrolysis of the monomer ...
Ring opening polymerization of 2,5-dihydro-2,5-dimethoxyfuran by electrochemical initiation
(Springer, 2004)
2,5-Dihydro-2,5-dimethoxyfuran (DHMF) was polymerized via constant current electrolysis (CCE), in CH3CN-NaClO4 solvent-electrolyte couple. Poly(DHMF) was obtained from the anolyte. The effect of current density, temperature, ...
Removal of cadmium (II) from aqueous solumns using sporopollenin
(Parlar Scientific Publications (P S P), 2004)
Sorption of cadmium ion from aqueous solution by sporopollenin, a polymer obtained from Lycopodium clavatum, was investigated. The influences of adsorption time, temperature, pH of solution, and Cd(II) concentration on the ...
