A tyrosinase-modified electrode, based on physical entrapment of enzyme in copolymer matrix of decanedioic acid bis(4-pyrrol-1-yl-phenyl) ester (DAPE) with pyrrole was constructed and used to investigate the total amount of phenolics in red wines. Kinetic parameters, V-max, and K-m, were determined. Also, temperature, pH optimizations, operational stability and shelf life of the enzyme electrode were examined. Surface morphologies of the films were studied by scanning electron microscope. (c) 2005 Wiley Periodicals, Inc.

Effect of ZnO type and concentration on the mophology, thermal, and mechanical properties of poly(ether ester)/ZnO composites ÇELEBİ, HANDE; Bayram, Göknur; DOĞAN, AYDIN (Wiley, 2013-09-15) Poly(ether ester) (PEE) copolymers were synthesized in a two-stage process involving transesterification and polycondensation. The synthesized copolymer and the zinc oxide (ZnO) were used in composite preparation by melt compounding. The influence of ZnO type and concentration on the morphology, thermal and mechanical properties of the composites were studied. DSC and XRD analyses indicated that crystallinity of composites was slightly reduced with ZnO content. Homogeneous dispersion of fillers in the polym...
Synthesis of N-polyethereal polypyrroles and their application for the preconcentration of rare earth ions Koksel, Bahar; CİHANER, ATİLLA; Kaya, Murat; Volkan, Mürvet; Önal, Ahmet Muhtar (Wiley, 2008-05-15) Conducting polymers containing polyether pseudocages (PI, PII, PIII) have been synthesized via chemical oxidation of 1,5-bis(1,1-pyrrole)-3-oxabutane (MI), 1,8-bis(I,I-pyrrole)-3,6-dioxahexane (MII), and 1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane (MIII) using anhydrous FeCl3 in CHCl3. Because as obtained polymer resins did not give any response toward any cations, they were reduced (undoped) using chemical reducing agents. Tetrabutylammonium hydroxide was found to be more effective in undoping to obtain mor...
Electrosynthesis of polyfuran in acetonitrile-boron trifluoride-ethyl ether mixture and its device application Tirkeş, Süha; Önal, Ahmet Muhtar (Wiley, 2007-01-15) Electrochemical polymerization of furan was achieved in acetonitrile/boron trifluoride/ethyl ether (CH3 CN/BF3/EE) mixture in the presence of tetrabutylammonium tetrafluoroborate via constant potential electrolysis at 1.4 V versus Ag/AgCl. Electrochemical behavior of furan was investigated in the same solvent mixture of varying ratios, utilizing cyclic voltammetry. Free-standing polyfuran (PFu) films were obtained in CH3CN/BF3/EE mixture (2/4/4; v/v/v) and characterized using FTIR spectroscopic technique. S...
Tailoring the Swelling and Glass-Transition Temperature of Acrylonitrile/Hydroxyethyl Acrylate Copolymers Aran, Bengi; SANKIR, MEHMET; Vargun, Elif; DEMİRCİ SANKIR, NURDAN; Usanmaz, Ali (Wiley, 2010-04-15) Novel polyacrylonitrile (PAN)-co-poly(hydroxyethyl acrylate) (PHEA) copolymers at three different compositions (8,12, and 16 mol % PHEA) and their homopolymers were synthesized systematically by emulsion polymerization. Their chemical structures and compositions were elucidated by Fourier transform infrared, H-1-NMR, and C-13-NMR spectroscopy. Intrinsic viscosity measurements revealed that the molecular weights of the copolymers were quite enough to form ductile films. The influence of the molar fraction of...
Synthesis and optical properties of light-emitting π-conjugated polymers containing biphenyl and dithienosilole LIAO, Liang; Çırpan, Ali; CHU, Qinghui; KARASZ, Frank E.; PANG, YI (Wiley, 2007-05-15) Copolymers containing oligo(phenylene vinylene) (2.5), fluorene, and 4,4-dihexyldithienosilole (DTS) units were synthesized and characterized. The pi-conjugated monomers were joined with the palladium(0)-catalyzed Suzuki-Miyaura coupling reaction, thus forming either biphenyl- or phenyl-thiophene linkages. These polymers were photoluminescent, with the fluorescent quantum efficiency between 54 and 63% and with),lambda(max) for fluorescence at similar to 448 nm in tetrahydrofuran. The presence of 5% DTS in t...
