Molecular-dynamics simulation of the structural stability, energetics, and melting of Cu-n(n=13-135) clusters
(Springer, 1997)
Cluster properties of copper have been investigated using the Molecular-Dynamics MD technique. The structural stability and energetics of spherical Cu, (n = 13 - 135) clusters have been investigated at temperatures T = 1 ...
Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels
(John Wiley & Sons Ltd, 1999)
Catalase was entrapped in thermally reversible poly (isopropylacrylamide-co-hydroxyethyl-methacrylate) (pNIPAM/HEMA) copolymer hydrogels. The thermoresponsive hydrogels, in cylindIl-rical geometry, were prepared in an ...
Comparison of β-galactosidase immobilization by entrapment in and adsorption on poly(2-hydroxyethylmethacrylate) membranes
(Royal Swedish Acad Sciences, 1996)
Schottky barrier height shifts depending on the interfacial layer as well as a change of the interface state charge with the forward bias while considering the presence of bulk (semiconductor) series resistance are discussed ...
Controlled release of Aldicarb from carboxymethylcellulose microcapsules
(Scientific Technical Research Council Turkey, 1997)
Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, ...
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 ...
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+ ...
Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies
(Springer Verlag, 1999)
Low molecular weight atactic polypropylene (APP) was functionalized with 4-allyl-2-methoxyphenol (eugenol), 4-allyl-1,2-dimethoxybenzene (DMAB), 4-propenylanisole(trans-anethole), cis-2,4,5-trimethoxypropenylbenzene ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ...
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 ...
Determination of Cu, Zn and Cd in water by FAAS after preconcentration by baker's yeast (Saccharomyces cerevisiae) immobilized on sepiolite
(Springer Verlag, 1999)
By using the adsorbent Saccharomyces cerevisine immobilized on sepiolite an adsorption-elution method was developed for the preconcentration of Cu, Zn, and Cd followed by flame atomic absorption spectrometry (FAAS). ...
