Single layer Fe(20Å) and Co(20Å) and multilayered Ag(20Å)/[Fe(20Å)/Ag(40Å) /Co(20Å)/Ag (40Å)]x3 /Ag(20Å) films were prepared in UHV by magnetron sputtering technique onto the silicon substates. Films were determined to have polycrystalline nature through SEM examination. Magnetization measurements were made on single and multilayer films. Due to the polycrystalline structure of the films, rounded magnetization curves were obtained. The GMR effect showed a rounded behaviour which also is an indication of the polycrystallinity of the films. The GMR effect, measured in Fe/Ag/Co multilayer structure, was analyzed with the help of magnetization behaviour of the multilayer structure and magnetization behaviour of the single layer films Fe(20Å)and Co(20Å).

MODELING PERMEATION OF MODIFIED ATMOSPHERE GAS-MIXTURES THROUGH A LOW-DENSITY POLYETHYLENE PACKAGE FILM ILTER, M; OZILGEN, M; ORBEY, N (Wiley, 1991-01-01) Permeation of individual gases through a low density polyethylene package film with CO2-N2 and CO2-O2-N2 mixtures was simulated with a simple mathematical model. Permeabilities of carbon dioxide were of the order of 10(-12) m3/s m2atm/m with CO2-N2 systems. Including oxygen in the system did not change carbon dioxide permeabilities. Permeabilities of oxygen were of the order of magnitude of 10(-9) m3/s m2atm/m with this system. When a CO2-O2-N2 mixture was humidified no substantial change was observed i...
Investigation of Photoluminescence Mechanisms from SiO2/Si:SiO2/SiO2 Structures in Weak Quantum Confined Regime by Deconvolution of Photoluminescence Spectra TUĞAY, EVRİN; Turan, Raşit (2016-04-01) Si nanocrystals embedded in SiO2 matrix were prepared by co-sputtering method followed by a post annealing process in N-2 ambient. By fixing sputtering parameters, the effects of annealing time and annealing temperature on the optical properties of Si nanocrystals are investigated. Origin and evolution of the photoluminescence (PL) in weak quantum confinement regime are discussed in the light of X-ray diffraction, Fourier transform infrared, and temperature dependent photoluminescence measurements. For all ...
A preliminary investigation of the environmental impact of a thermal power plant in relation to PCB contamination Gedik, Kadir; İmamoğlu, İpek (Springer Science and Business Media LLC, 2011-07-01) Purpose The most significant application of polychlorinated biphenyls (PCBs) is in transformers and capacitors. Therefore, power plants are important suspected sources for entry of PCBs into the environment. In this context, the levels and distribution of PCBs in sediment, soil, ash, and sludge samples were investigated around Seyitomer thermal power plant, Kutahya, Turkey. Moreover, identity and contribution of PCB mixtures were predicted using the chemical mass balance (CMB) receptor model.
Enhanced Optical Absorption and Spectral Photocurrent in a-Si:H by Single- and Double-Layer Silver Plasmonic Interfaces Saleh, Zaki M.; NASSER, Hisham; ÖZKOL, Engin; GÜNÖVEN, Mete; ALTUNTAS, Burcu; Bek, Alpan; Turan, Raşit (2014-04-01) Single and double plasmonic interfaces consisting of silver nanoparticles embedded in media with different dielectric constants including SiO2, SiNx, and Al:ZnO have been fabricated by a self-assembled dewetting technique and integrated to amorphous silicon films. Single plasmonic interfaces exhibit plasmonic resonances whose frequency is red-shifted with increasing particle size and with the thickness of a dielectric spacer layer. Double plasmonic interfaces consisting of two different particle sizes exhib...
A study on nanofiller effects of serpentine in polypropylene matrix Tan, Semra; Tincer, İsmail Teoman (2012-04-15) The nanocomposite materials were prepared using serpentine as filler and polypropylene (PP) as the matrix in the presence of maleic anhydride grafted polypropylene (PP-g-MA) compatibilizer. The melt intercalation was carried out following serpentine modification with a quaternary salt of cetyl-trimethyl-ammonium bromide. The structure of nanocomposites was shown by X-ray diffraction (XRD) and transmission electron microscopy (TEM) studies. Thermal analysis performed by differential scanning calorimetry (DSC...
