Desized polyacrylonitrile (PAN) based carbon fibers (CF) were chemically and electrochemically oxidized and reduced. CF surfaces were activated via cyclic voltammetry studies with anodic and cathodic scans. The changes in CF surfaces were studied by contact angle measurements. Lifshitz-van der Waals and acid-base components of single fibers were determined. In general, oxidation resulted in the formation of an acidic surface energy component and reduction gave rise to no change in the number of basic functionalities at the CF surface.

ELECTROCHEMICAL BEHAVIOR OF MOCLOBEMIDE AT MERCURY AND GLASSY CARBON ELECTRODES AND VOLTAMMETRIC METHODS FOR ITS DETERMINATION
Altunöz Erdoğan, Deniz; Tasdemir, Ibrahim Hudai; Erk, Nevin; Kilic, Esma (2011-01-01)
Electrochemical oxidation and reduction properties of Moclobemide (MCB) were investigated at glassy carbon electrode (GCE) and hanging mercury drop electrode (HMDE). Diffusion-adsorption behavior and some extra electrochemical parameters such as diffusion coefficient, number of transferred electrons and proton participated to its electrode mechanisms on both electrode and surface coverage coefficient were calculated from the results of cyclic voltammetry and square-wave voltammetry. Reversible catalytic hyd...
A New Voltammetric Method for the Determination of Lercanidipine in Biological Samples
Ozturk, Funda; Tasdemir, Ibrahim Hudai; Altunöz Erdoğan, Deniz; Erk, Nevin; Kilic, Esma (2011-01-01)
Electrochemical behavior and adsorption-diffusion properties of lercanidipine (LCN) on a glassy carbon electrode (GCE) were investigated in a mixture of ethanol-Britton Robinson buffer (BR) using voltammetric methods. From experimental results LCN was found to be reduced irreversibly via a single four-electron process controlled mainly by diffusion with some adsorption contribution at about -0.65 V (vs. Ag/AgCl reference electrode). Therefore, a new, accurate, rapid, selective and simple square-wave cathodi...
Investigation of sludge viscosity and its effects on the performance of a vacuum rotation membrane bioreactor
KOMESLİ, Okan Tarık; Gökçay, Celal Ferdi (Informa UK Limited, 2014-03-04)
Sludge characteristics of a full-scale vacuum rotation membrane (VRM) bioreactor having plate-type membranes with 0.038 m nominal pore size and 540 m(2) surface area were investigated. The VRM plant is composed of an aeration tank and a filtration chamber. The sludge floc size distribution, as determined microscopically, was mainly between 0 and 100 m in the filter chamber with very little difference in size distribution between summer (20-25 degrees C) and winter (10-15 degrees C) seasons. Small floc size ...
Electrochemical behaviour and electrochemical polymerization of fluoro-substituted anilines
Cihaner, A; Önal, Ahmet Muhtar (2002-08-01)
The electrochemical behaviour of three fluoro-substituted aniline monomers, 2-fluoroaniline (2FAN), 3-fluoroaniline (3FAN) and 4-fluoroaniline (4FAN), was investigated in aqueous acidic and organic media by means of cyclic voltammetry (CV) studies. Constant potential electrolysis (CPE) of the monomers in acetonitrile-water mixture (1: 1 by volume) using NaClO4 as supporting electrolyte yielded soluble polymers. The mechanism of electrochemical polymerization was investigated using in situ electron spin reso...
Synthesis, characterizations and photovoltaic applications of dithienothiophene and benzotriazole containing conjugated polymers
Cevher, Şevki Can; Çırpan, Ali; Toppare, Levent Kamil; Department of Chemistry (2013)
Fused bithiophene containing conjugated polymers are recently used in different applications; for example organic light emitting diodes, solar cells, electrochromic devices and organic field effect transistors. Fused bithiophene derivatives increase the planarity, charge mobility and decrease band gap when incorporated into the polymer backbone. Connecting atom between the bithiopheneunit can be phosphorous, silicon, nitrogen and sulphur. In this thesis, dihienothiophene was coupled with benzotriazole via S...
