Biosorption of copper(II) on immobilised Synechocystis aquatilis
Ergene, A; Tan, S; Katircioglu, H; Oktem, Z (Parlar Scientific Publications (P S P), 2006)Synechocystis aquatilis was immobilized in Ca-alginate via entrapment. The plain alginate, and alive and heat-inactivated immobilized algae beads were used for the sorption of Cu2+ ions from aqueous solutions at 25 degrees ... -
Biosorption of reactive dyes on Scenedesmus obliquus
Tan, S; Katircioglu, H; Oktem, Z; Ergene, A (Elsevier Science Bv, 2005)… -
Electrochemical polymerization of 4-allyl-1,2-dimethoxybenzene
Testereci, HN; Akin-Oktem, G; Oktem, Z (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 ... -
Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies
Oktem, Z; Cetin, S; Akin-Oktem, G (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 ... -
Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
Akin-Oktem, G; Cetin, S; Oktem, Z (Springer, 2000)Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-me ... -
Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels
Arica, MY; Oktem, HA; Oktem, Z; Tuncel, SA (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 ...
