Positively and negatively charged states in cPBEBT, which consists of EDOT/benzotriazole/EDOT as the building block, are studied using CV, in situ UV-Vis, and FTIR-ATR spectroscopy. The results show that cPBEBT is an ambipolar D-A-type polymer capable of conducting both holes and electrons. The injected positive and negative charges are distributed over the whole polymer backbone, which is proven by in situ FTIR-ATR where spectral signatures associated with the benzotriazole unit are observed in both p- and n-doped cPBEBT. HOMO and LUMO values obtained from CV and FTIR-ATR experiments during oxidation and reduction are compared. cPBEBT is an example of the D-A approach towards the improvement of the electronic properties of the resultant polymer.

Spectroelectrochemistry of potassium ethylxanthate, bis(ethylxanthato)nickel(II) and tetraethylammonium tris(ethylxanthato)nickelate(II) Dag, O; Yaman, SO; Önal, Ahmet Muhtar; Isci, H (2001-10-07) Electrochemical and chemical oxidation of S2COEt-, Ni(S2COEt)(2), and [Ni(S2COEt)(3)](-) have been studied by CV and in situ UV-VIS spectroscopy in acetonitrile. Cyclic voltammograms of S2COEt- and Ni(S2COEt)(2) display one (0.00 V) and two (0.35 and 0.80 V) irreversible oxidation peaks, respectively, referenced to an Ag/Ag+ (0.10 M) electrode. However, the cyclic voltammogram of [Ni(S2COEt)(3)](-) displays one reversible (- 0.15 V) and two irreversible (0.35, 0.80 V) oxidation peaks, referenced to an Ag/Ag...
Combinatorial development of LSF-based cathode materials for intermediate temperature solid oxide fuel cells Kılıç, Fahrettin; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2021-6) This thesis focuses on the synthesis, characterization, and processing of LSF based composite cathode for solid oxide fuel cells. The cathode comprises three oxides; LSM, LSF and ScSZ which are synthesized by co-sputtering using combinatorial approach. The electrolyte was Scandia doped Zirconia(ScSZ), as it has attractive ionic conductivity at lower temperatures. Having chosen the electrolyte ScSZ as electrolyte. After detailed analysis with regard to conductivity and thermal expansion for each oxide, the c...
In situ and operando observation of surface oxides during oxygen evolution reaction on copper Toparlı, Çiğdem; Wieck, Andreas D.; Rohwerder, Michael; Erbe, Andreas (2017-05-01) Formation and dissolution of oxide on copper under transpassive conditions, i.e. during OER and transpassive dissolution, in alkaline electrolyte was investigated by a combination of electrochemical techniques and in situ and operando Raman and photoluminescence (PL) spectroscopy, as well as spectropscopic ellipsometry. Experiments were conducted under potentiodynamic and potentiostatic polarisation in 0.1M NaOH. In chronoamperometry experiments with steps between potentials, oxide thickness continued incre...
Kinetic study of the reaction between hydroxyl-terminated polybutadiene and isophorone diisocyanate in bulk by quantitative FTIR spectroscopy Kincal, D; Özkar, Saim (Wiley, 1997-12-05) A kinetic study of the reaction between a hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) was carried out in the bulk state by using quantitative Fourier transform infrared(FTIR) spectroscopy. The reaction is shown to obey a second-order rate law, being first order in both the HTPB and IPDI concentrations. The activation parameters obtained from the evaluation of kinetic data are Delta H-double dagger = 41.1 +/- 0.4 kJ mol, Delta S-double dagger = -198 +/- 2 J K-1 mol(-1) and E-a...
Multi scale modeling of dual phase steels with integrated computational materials engineering framework Bakkalbaşı, Doğucan; Şimşir, Caner; Music, Omer; Department of Metallurgical and Materials Engineering (2022-11-21) In this thesis, process-chain simulation of of Dual-Phase (DP) steels (DP600, DP800) with different chemical compositions and manufacturing histories is performed, in line with Integrated Computational Materials Engineering (ICME) principles. To do this, the required material data is acquired by multi-scale modelling, which enables bi-directional link between the material production processes with the manufacturing processes. The thesis consists of 2 important stages, each of which includes innovation...
