Novel dye-attached macroporous films for cadmium, zinc and lead sorption: Alkali Blue 6B-attached macroporous poly(2-hydroxyethyl methacrylate)
(Elsevier Science Bv, 1998)
Alkali Blue GB-attached poly(2-hydroxyethyl methacrylate) (poly(HEMA)) microporous films were investigated as chelate forming sorbents for heavy metal removal. Poly(HEMA) microporous films were prepared by UV-initiated ...
Dye derived and metal incorporated affinity poly(2-hydroxyethyl methacrylate) membranes for use in enzyme immobilization
(John Wiley & Sons Ltd, 1998)
Microporous poly(2-hydroxyethyl methacrylate) (PHEMA) membranes were prepared by W-initiated photopolymerization of HEMA in the presence of an initiator (alpha,alpha'-azobisisobutyronitrile, AIBN). An affinity dye Cibacron ...
Cibacron Blue F3GA and Cu(II) derived poly(2-hydroxyethylmethacrylate) membranes for lysozyme adsorption
(Elsevier Science Bv, 1998)
Lysozyme adsorption onto Cibacron Blue F3GA and Cu(II) derived poly(2-hydroxyethyl methacrylate) [poly(HEMA)] membranes was investigated. Microporous poly(HEMA) membranes were prepared by photopolymerization of HEMA. The ...
A fuzzy colour quantizer for renderers
(Elsevier Science Bv, 1998)
This paper presents a new colour quantization method for ray tracing. Normally, quantization is carried out by generating statistics about the colours present in the original image. Then a colour look-up table is created ...
Dye-ligand and metal chelate poly(2-hydroxyethylmethacrylate) membranes for affinity separation of proteins
(Elsevier Science Bv, 1998)
Cibacron Blue F3GA was covalently immobilized onto poly(2-hydroxyethyl methacrylate) (pHEMA) membranes via the nucleophilic reaction between the chloride of its triazine ring and the hydroxyl group of pHEMA. Then, Fe3+ ...
A certain subclass of analytic functions involving operators of fractional calculus
(Pergamon-Elsevier Science Ltd, 1998)
Making use of certain operators of fractional calculus, we introduce a new class T-mu(n,lambda,alpha) of functions which are analytic and univalent in the open unit disk U and obtain a necessary and sufficient condition ...
Immobilization of glucoamylase onto activated pHEMA/EGDMA microspheres: properties and application to a packed-bed reactor
(Elsevier Science Inc, 1998)
Glucoamylase was covalently immobilized onto pHEMA/EGDMA microspheres of two different sizes: 50-100 mu m and 100-200 mu m in diameter. The activity of the enzyme on smaller microspheres was found to be almost twice that ...
Adaptive multi-element synthetic aperture imaging with motion and phase aberration correction
(Ieee-Inst Electrical Electronics Engineers Inc, 1998)
Multi-element synthetic aperture techniques employing subaperture processing over successive firing steps can produce good image quality with simple front-end hardware but are susceptible to motion and phase aberration ...
New metal chelate sorbent for albumin adsorption: Cibacron blue F3GA-Zn(II) attached microporous poly(HEMA) membranes
(John Wiley & Sons Inc, 1998)
Poly(2-hydroxyethyl methacrylate) [poly(HEMA)] membranes were prepared by UV-initiated photopolymerization of HEMA in the presence of an initiator (alpha-alpha'-azobis-isobutyronitrile, AIBN). The triazine dye Cibacron ...
Adsorption of copper(II), cobalt(II), and iron(III) ions from aqueous solutions on poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 1998)
The adsorption behavior of poly(ethylene terephthalate) (PET) fibers towards copper(II), cobalt(II), and iron(III) ions in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment time, ...
