The electrochemical synthesis of poly(o-anisidine) (POA) was achieved on brass (CuZn) electrode by applying two scan rates (50 and 20 mVs(-1)). The synthesized polymer films were strongly adherent and homogeneous in both cases. Their corrosion performance was investigated by AC impedance spectroscopy (EIS) technique, anodic polarization plots and open circuit potential-time curves, in 3.5% NaCl solution. It was clearly seen that poly(o-anisidine) films provided a significant physical protection for longer exposure time. It was shown that polymer film coated at high scan rate (CuZn/POA-H) exhibited better barrier property against the attack of corrosive agents when compared with polymer film obtained at low scan rate (CuZn/POA-L). It was found out that poly(o-anisidine) film synthesized at high scan rate caused a significant increase in corrosion resistance by its catalytic behavior on formation of protective oxide layers on the surface in longer time.

Vulcan-Supported Pt Electrocatalysts for PEMFCs Prepared using Supercritical Carbon Dioxide Deposition Bayrakceken, Ayse; Smirnova, Alevtina; Kitkamthorn, Usanee; Aindow, Mark; Tuerker, Lemi; Eroğlu, İnci; ERKEY, CAN (Informa UK Limited, 2009-01-01) In this study, supercritical carbon dioxide (scCO(2)) deposition was used to prepare vulcan-supported Pt (Pt/Vulcan) electrocatalysts for proton exchange membrane fuel cells (PEMFCs), and the effects of process variables on the properties of the electrocatalysts were investigated. The two different methods used to reduce the organometallic precursor were thermal reduction in nitrogen at atmospheric pressure and thermal reduction in scCO(2). In the former method, the maximum Pt loading achieved was 9%, and t...
THERMAL AND MASS DIFFUSIVITY FROM DYNAMIC SINGLE PELLET EXPERIMENTS DOGU, G; CABBAR, C; Doğu, Timur (Informa UK Limited, 1991-01-01) The single-pellet moment techniques previously developed for the evaluation of effective diffusion coefficient and effective thermal conductivity of a porous solid are combined and a procedure is proposed for the simultaneous evaluation of these constants from a single set of pulse response experiments. It is shown that both temperature and concentration response curves can be measured from a single pulse of oxygen injected into hydrogen carrier gas flowing past a catalyst pellet. It is shown that the zerot...
AXIAL DISPERSION OF LIQUID IN MOBILE-BED CONTACTING Uysal, B.Z; Özilgen, M. (Informa UK Limited, 1989-7) Axial dispersion of liquid in Mobile-Bed Contacting (MBC) was investigated employing transient-response technique with impulse input of NaCI tracer. Experiments were performed in a 0.195 m ID column. Three different packing diameters (15, 19.5 and 32 mm) and three different static bed heights (0.1, 0.195 and 0.3 m) were used. Gas flow rate was varied between 3.02 and 4.05 kg/m2/s and liquid flow rate from 2.4 to 10.4 kg/m2/s. Transfer function analysis of data yielded that Peclet number was practically ind...
Germanium determination by flame atomic absorption spectrometry: An increased vapor pressure-chloride generation system Kaya, Murat; Volkan, Mürvet (Elsevier BV, 2011-03-15) A new chloride generation system was designed for the direct, sensitive, rapid and accurate determination of the total germanium in complex matrices. It was aimed to improve the detection limit of chloride generation technique by increasing the vapor pressure of germanium tetrachloride (GeCl4). In order to do so, a novel joint vapor production and gas-liquid separation unit equipped with a home-made oven was incorporated to an ordinary nitrous oxide-acetylene flame atomic absorption spectrometer. Several va...
Micro fluxgate sensor with cascaded planar ring cores Zorlu, O.; Kejik, P.; Teppan, W. (2009-09-09) In this paper, we present a new microfabricated fluxgate sensor structure having cascaded planar rings as the ferromagnetic core. A circular magnetic excitation is provided with a rod passing through the FeNi rings as a sewing thread. Planar coils placed under the edges of the core are used as sensing elements. The sensing coils and the excitation rod are made of AlSi, and the planar FeNi ferromagnetic core is electroplated in between the excitation rod metallization. The sensor with 18 cascaded cores has 6...
