Electrochemically prepared films of conducting polymers of polypyrrole and polythiophene and their blends with polyamide have been investigated by X-ray photoelectron spectroscopy. In the N1s region of the spectra of films containing polypyrrole the peak corresponding to N+ at 402.0 eV is separated from that of neutral N. The intensity of the N+ peak can be correlated with the electrical conductivity of the films and the spectroscopically derived ratio of F/N+ is close to 4 indicating that one BF4- dopant ion is incorporated for every oxidized nitrogen center. In the spectra of films of polythiophene and its blends peaks corresponding to S and S+ can not be resolved but again the F/C ratio correlates with the electrical conductivity.

X-ray photoelectron spectroscopic characterization of Au collected with atom trapping on silica for atomic absorption spectrometry Suzer, S; Ertas, N; Kumser, S; Ataman, Osman Yavuz (1997-10-01) The nature of analyte species collected on a cooled silica tube for atom-trapping atomic absorption spectrometric determination was investigated with the use of X-ray photoelctron spectroscopy (XPS). An XPS spectrum of gold deposited on atom-trapping silica tubes reveals a Au 4f(7/2) peak with a binding energy of 84.8 (+/-0.2) eV, which falls in the middle of the binding energies corresponding to zerovalent Au(0) at 84.0 eV and that of monovalent Au(I) at 85.2 eV, The corresponding energy for Au vapor depos...
X-ray-induced production of gold nanoparticles on a SiO2/Si system and in a poly(methyl methacrylate) matrix Karadas, F; Ertaş, Gülay; Ozkaraoglu, E; Suzer, S (2005-01-04) Prolonged exposure to X-rays of HAuCl4 deposited from an aqueous solution onto a SiO2/Si substrate or into a poly(methyl methacrylate) (PMMA) matrix induces reduction of the Au3+ ions to Au-0 and subsequent nucleation to gold nanoclusters as recorded by X-ray photoelectron spectroscopy. The corresponding major oxidation product is determined as chlorine {HAuCl4(ads) + X-rays --> Au(ads) + (3/2)Cl-2(ads) + HCl(ads)}, which is initially adsorbed onto the surface but eventually diffuses out of the system into ...
X-ray timing properties of four anomalous x-ray pulsars: 4u 0142+61, 1e 2259+586, 1rxs j170849.0_400910, and 1e 1841_045 Çerri, Danjela; Baykal, Altan; İnam, Sıtkı Çağdaş; Department of Physics (2015) In this thesis, the detailed X-ray timing characteristics of four Anomalous X-Ray Pulsars (AXPs); 4U 0142+61, 1E 2259+586, 1RXS J170849.0 -400910, and 1E 1841- 045 are presented for glitch free time intervals using data taken by Rossi X-Ray Timing Explorer (RXTE). The pulse arrival times of these AXPs are evaluated by phase coherent timing method. After the removal of the spin-down trend from pulse arrivals, remaining residuals are used for estimation of their noise strengths. Possible correlation of the no...
X-ray photoelectron spectroscopy study on the photodegradation of copolyester model compounds Arangdad, Kiarash; Yıldırım, Erol; Detwiler, Andrew; Cleven, Curtis D.; Burk, Christopher; Shamey, Renzo; Pasquinelli, Melissa A.; Freeman, Harold; El-Shafei, Ahmed (Wiley, 2020-07-01) The photodegradation of irradiated PETG and PCCT model compounds namely Tm-CHDM-Tm and Tm-TMCD-Tm, where Tm refers to the methyl ester of terephthalic acid, CHDM refers to 1, 4-cyclohexanedimethanol, and TMCD refers to tetramethyl-1, 3-cyclobutanediol, was analyzed using X-ray photoelectron spectroscopy. Photodegradation products were characterized based on high resolution O(1s)x-ray photoelectron spectroscopy (XPS) spectra and the spectra of irradiated model compounds showed a decrease in the relative inte...
X-ray observations of accretion powered pulsars İnam, Sıtkı Çağdaş; Baykal, Altan; Department of Physics (2004) In this thesis, X-ray observations of four accretion powered pulsars are presented. Using RXTE observations of 4U 1907+09, we found three new pulse periods of the source. We found that the source spun-down almost at a constant rate of Þ
