Catalase adsorption onto cibacron blue F3GA and Fe(III)derivatized poly(hydroxyethyl methacrylate) membranes and application to a continuous system
(Elsevier Science Bv, 1997)Poly(2-hydroxyethyl methacrylate) (poly(HEMA)) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (a-a'-azobisisobutyronitrile, AIBN). An affinity dye, i.e. Cibacron Blue ... -
Graft copolymerization of n-vinyl-2-pyrrolidone on dimethyl sulfoxide pretreated poly(ethylene terephthalate) films using azobisisobutyronitrile initiator
(John Wiley & Sons Inc, 1997)Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone (n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140 degrees C before ... -
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(John Wiley & Sons Ltd, 1997)beta-Galactosidase was immobilized in/on poly(2-hydroxyethyl methacrylate) (pHEMA) membranes by two different methods: adsorption on Cibacron F3GA derivatized pHEMA membranes (pHEMA-CB), and entrapment in the bulk of the ... -
A numerical study of laminar heat convection in ducts of irregular cross-sections
(Pergamon-Elsevier Science Ltd, 1997)Forced convective heat transfer during hydrodynamically fully developed laminar fluid flow inside ducts of irregular cross section is analyzed utilizing numerical methods. The elliptic grid generation technique is used to ... -
Molecular-dynamics simulation of the structural stability, energetics, and melting of Cu-n(n=13-135) clusters

Some families of multivalently analytic functions with negative coefficients
(Academic Press Inc Jnl-Comp Subscriptions, 1997)The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these ... -
Selectivity and kinetics of ligand exchange of anions in a chelate ion exchanger
(Gauthier-Villars, 1997)Ligand selectivity plots and interdiffusion coefficients are presented for the chloride form of a ligand exchanger chemically derived from sporopollenin. Exchanges of iodide and bromide for chloride as the ligand were ... -
The study of kinetic models for ligand exchange of anions as ligands using ligand-exchange resin
(John Wiley & Sons Inc, 1997)A comparative study of kinetic models for ligand exchange of I- --> Cl- and Br- --> Cl- as ligands as a function of pH and concentration using diaminoethyl-sporopollenin (DAE-sporopollenin) resin were investigated during ... -
Analysis of energy flow in thick plate structures
(Pergamon-Elsevier Science Ltd, 1997)At sufficiently high frequencies: where the structural wavelength is much smaller than the thickness of the structure, the rotational inertia and transverse shear effects become increasingly important. In this study the ... -
Cibacron Blue F3GA-incorporated macroporous poly(2-hydroxyethyl methacrylate) affinity membranes for heavy metal removal
(Elsevier Science Bv, 1997)Macroporous poly(2-hydroxyethyl methacrylate), poly(HEMA), membranes were prepared by UV-initiated photo-polymerization of HEMA in the presence of an initiator (azobisisobutyronitrile, AIBN). An affinity dye, i.e., Cibacron ... -
