A glucose biosensor based on a newly designed and synthesized polymer, poly[(E)-6-methyl-6 '-(10-methylanthracen-9-yl)-1,1 '-diundecyl-[3,3 '-biindolinylidene]-2,2 '-dione] (namely PIIDAnth), and single walled carbon nanotubes (SWCNTs) was fabricated via an easy one pot electrode preparation and explored as a glucose electrochemical sensor. The key aim of this paper is to emphasize creation of the new surface design of sensing platforms based on a novel polymer and nanomaterial for glucose detection. With the insertion of single walled carbon nanotubes (SWCNTs) into the biosensing system the sensor showed remarkable advantages for glucose detection including high sensitivity and low detection limit. In addition, electrochemical analysis of the polymer was investigated. The enzyme biosensor showed a linear range from 0.05 mM to 1.0 mM (R-2 = 0.994) with a great sensitivity of 61.23 mu A mM(-1) cm(-2) and low detection limit of 0.026 mM. The apparent Michaelis-Menten constant (KappM) was estimated to be 0.8 mM. Cyclic voltammetry (CV) and scanning electron microscopy (SEM) images revealed the electrochemical and morphologic features. The fabricated sensor was also tested in commercial beverages, successfully. Amperometric measurements proved that PIIDAnth/SWCNT/GOx coating is an excellent structure for glucose sensing.

A novel integrated process for the functionalization of methane and ethane: bromine as mediator
Lorkovic, IM; Yılmaz, Ayşen; Yilmaz, GA; Zhou, XP; Laverman, LE; Sun, SL; Schaefer, DJ; Weiss, M; Noy, ML; Cutler, CI; Sherman, JH; McFarland, EW; Stucky, GD; Ford, PC (Elsevier BV, 2004-11-24)
We describe a novel, integrated multi-step process for the partial oxidation of alkanes to alcohols, ethers or olefins using O-2 as oxidant. The sequential transformations are (1) alkane bromination to alkyl bromide(s) and HBr, (2) reaction of this mixture with solid metal oxide (MO) to neutralize the HBr and to generate oxygenated products or olefins plus solid metal bromide, and (3) oxidation of the spent solid with 02 to regenerate the metal oxide and Br-2 for reuse.
A new p- and n-dopable selenophene derivative and its electrochromic properties
Cetin, Guelben Ardahan; Balan, Abidin; Durmus, Asuman; Günbaş, Emrullah Görkem; Toppare, Levent Kamil (Elsevier BV, 2009-02-01)
A novel electrically conducting polymer, poly(2-dodecyl-4,7-di(selenophen-2-yl)benzotriazole) (PSBT), containing selenophene as the strong donor and benzotriazole as the strong acceptor groups was synthesized by electrochemical polymerization. Homopolymerization and copolymerization (in the presence of 3,4-ethylenedioxythiophene (EDOT)) were achieved in acetonitrile/dichloromethane(95/5 v/v) with 0.1 M tetrabutylammonium hexafluorophosphate (TBAPF(6)). The electrochemical and optical properties of homopolym...
The C-11-radioisotopic study of methanol conversion on V-MCM-41: The influence of methyl iodide on the transformation
Sarkadi-Priboczki, E.; Gucbilmez, Y.; Solmaz, A.; Balci, S.; Szelecsenyi, F.; Kovacs, Z.; Doğu, Timur (Elsevier BV, 2009-04-30)
The methanol conversion and a feasible methanol co-reaction with methyl iodide were studied on a vanadium incorporated MCM-41 type (V-MCM-41) mesoporous catalyst. which was prepared by a direct hydrothermal synthesis method. Adsorption/desorption as well as conversion derivates of radioactive methanol were easily followed by radioactivity detectors on V-MCM-41. The transformation and coreaction products were analyzed by a gas chromatograph equipped with Radio/FID detectors. The radiodetector was applied to ...
A novel multi-electrochromic polymer based on selenophene and benzotriazole via electrochemical and chemical polymerization
Demir, Fatma; Keles, Duygu; Karabag, Aliekber; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2019-03-04)
In this study, a novel donor-acceptor type monomer was designed based on selenophene and benzotriazole with a bulky pendant group and synthesized through Stille coupling reaction. The monomer was polymerized electrochemically by using cyclic voltammetry and also chemically by oxidation in the presence of FeCl3. Both polymers were then compared in terms of their optical properties, electrochemical and spectroelectrochemical behaviors, kinetic and colorimetric properties and surface morphologies. Independent ...
Preparation and characterization of a new CdS-NiFe2O4/reduced graphene oxide photocatalyst and its use for degradation of methylene blue under visible light irradiation
Bagherzadeh, Mojtaba; Kaveh, Reyhaneh; Özkar, Saim; AKBAYRAK, SERDAR (Springer Science and Business Media LLC, 2018-10-01)
In this paper, CdS nanoparticles as a visible light active photocatalyst were coupled by NiFe2O4 and reduced graphene oxide (rGO) to form CdS-NiFe2O4/rGO nanocomposite by facile hydrothermal methods. The CdS-NiFe2O4/rGO nanocomposite shows enhanced photocatalytic activity for the degradation of methylene blue (MB) under visible light illumination. In addition to improved photocatalytic performance, this prepared nanocomposite shows increased photostability and is magnetically separable from the aqueous medi...
