3-Aminophenylcalix[4]pyrrole (3APCP) was grafted to a glassy carbon (GC) surface during the electrochemical oxidation process in 0.1 M tetrabutylammoniumtetra-fluoroborate (TBATFB) containing acetonitrile solution. The presence of a surface film was confirmed electrochemically by comparing voltammograms of dopamine and ferricyanide redox probes at the bare and modified electrodes. Reflection-absorption infrared spectroscopy (RAIRS), XPS, atomic force microscopy (AFM), ellipsometry and the contact angle measurements were also employed to characterize 3APCP film on GC electrode. RAIRS analysis revealed that calix[4]pyrrole was bonded to the glassy carbon surface via the etheric linkage. The stability of the modified GC electrode was also studied.

Effects of gold-induced crystallization process on the structural and electrical properties of germanium thin films Kabacelik, Ismail; Kulakci, Mustafa; Turan, Raşit; ÜNAL, NURİ (Wiley, 2018-07-01) Gold-induced (Au-) crystallization of amorphous germanium (-Ge) thin films was investigated by depositing Ge on aluminum-doped zinc oxide and glass substrates through electron beam evaporation at room temperature. The influence of the postannealing temperatures on the structural properties of the Ge thin films was investigated by employing Raman spectra, X-ray diffraction, and scanning electron microscopy. The Raman and X-ray diffraction results indicated that the Au-induced crystallization of the Ge films ...
Effect of heat treatment on the stress and structure evolution of plasma deposited boron nitride thin films Anutgan, T. Aliyeva; Anutgan, M.; Wdemir, O.; Atilgan, I.; Katircioglu, B. (Elsevier BV, 2008-03-25) Boron nitride (BN) thin films are deposited at 573 K by plasma enhanced chemical vapor deposition (PECVD) with ammonia (NH3) and hydrogen diluted diborane (15% B2H6 in H-2) source gases. UV-visible and Fourier transform infrared (FTIR) spectroscopies together with surface profilometry are used for the film characterization. These films are hydrogenated (BN:H) whose hydrogen content is pursued following the 1.5 h annealing process at 748 K, 923 K and 1073 K under nitrogen atmosphere. Hydrogen escape with the...
Effect of low-energy electron irradiation on (Bi, Pb)-2212 superconductors Ogun, SE; Goktas, H; Ozkan, H; Hasanlı, Nızamı (Elsevier BV, 2005-06-22) The effect of low-energy electron irradiation on the properties of the Bi-based superconductors is studied. Two sets of polycrystalline (Bi, Pb)-2212 samples were synthesized by heating the appropriate mixtures of powders at 840 degrees C for 100 h, then quenched or furnace cooled to room temperature. The samples were irradiated by low-energy (1-10 keV), pulsed (20 ns) electron beam up to a dose of 6.2 x 10(15) cm(-2). X- ray diffraction patterns, resistance-temperature behaviours, critical currents, and mi...
Electronic and structural properties of armchair SWCNT/TiO2(110)-(1 x 2) system Tayran, C.; ÇAKMAK, MELEK; Elliatioglu, S. (Elsevier BV, 2011-03-01) We have presented structural and electronic properties of single-walled carbon nanotubes (CNTs) with armchair chirality on the reconstructed rutile TiO2(110)-(1 x 2) surface by means of ab initio calculations using density functional theory. For the TiO2 surface reconstruction, we have adopted an added-row model which was experimentally proposed in parallel to STM patterns and theoretically agreed by first principle calculations. In this work, we have studied, as examples, two CNTs with different sizes, (3,...
Characterization and Electrical Conductivity of Poly(ethylene glycol)/Polyacrylonitrile/Multiwalled Carbon Nanotube Composites Aqeel, Salem M.; Kucukyavuz, Zuhal (Wiley, 2011-01-05) Polymer blends based on poly(ethylene glycol), polyacrylonitrile, and multiwalled carbon nanotubes (MWNTs) were prepared by the solvent cast technique from the dispersion of the MWNTs in the concentration range 0-3.45 wt %. The interaction of the MWNTs with the polymer blend was confirmed by a Fourier transform infrared (FTIR) spectroscopy study. The thermal properties of the polymer blend with the MWNTs were carried out by means of differential scanning calorimetry (DSC). It was evident from DSC that the p...
