Covalent immobilization of invertase on chemically activated poly (styrene-2-hydroxyethyl methacrylate) microbeads
Altinok, Haydar; Aksoy, Serpil; Tumturk, Hayrettin; Hasirci, Nesrin (Wiley, 2008)A carrier for invertase enzyme was synthesized from styrene (S) and 2- hydroxyethyl methacrylate (HEMA) in the form of microbeads. These poly (styrene-2-hydroxyethyl methacrylate), P(S-HEMA) microbeads were activated by ... -
Effect of polycondensation reaction conditions on the properties of thermotropic liquid-crystalline copolyester
Yikici, Meryem; Yerlikaya, Zekeriya; Aksoy, Serpil; Altinok, Haydar (Taylor & Francis Inc, 2008)In this study a range of wholly aromatic copolyesters based on kink m-acetoxybenzoic acid (m-ABA) monomer (33 mol%) and equimolar-linear p-acetoxybenzoic acid (p-ABA), hydroquinone diacetate (HQDA) and terephthalic acid ... -
Immobilization of glucose isomerase in surface-modified alginate gel beads
Tumturk, Hayrettin; Demirel, Gokhan; Altinok, Haydar; Aksoy, Serpil; Hasirci, Nesrin (Wiley, 2008)In this study, glucose isomerase enzyme was entrapped into modified and nonmodified calcium alginate gel beads. Various characteristics of free and immobilized enzymes such as the optimum pH, temperature and dependence of ... -
Thermal properties and crystallinity of thermotropic liquid crystalline copolyesters prepared from poly(ethylene terephtalate) (PET) and rigid aromatic units
Tan, Abdullah; Altinok, Eaydar; Yerlikaya, Zekeriya; Aksoy, Serpil (Taylor & Francis Inc, 2007)A series of copolyesters were synthesized by rnelt-polycondensation reaction of poly(ethylene terephtalate) (PET) with various proportions of equimolar compositions of p-acetoxybenzoic acid (p-ABA), hydroquinone diacetate ...
