Magnesium thin films of 350 nm, capped with Pd, were deposited on glass substrates and hydrogenated in two different conditions; namely isochronal and isothermal. As-deposited films were highly textured with Mg (001) parallel to the glass substrate. Experiments have shown that under isothermal conditions starting from 333 K, Mg films can absorb hydrogen producing MgH(2) with a random texture. When the films were heated slowly starting from the room temperature, hydrogenation gives rise to a textured MgH2, where (110) parallel to the substrate. (101) is also present in this texture as a minor component. Formation of the textured hydride in isochronal loading was discussed within the context of the lattice mismatch in a Mg to MgH(2) transformation.

Isochronal hydrogenation of textured magnesium/palladium thin films Özgit, Çağla; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2009) Pure and palladium‐covered 350 nm thick magnesium thin films were deposited on glass substrates via thermal evaporation. In the as‐deposited state, films were highly textured with Mg (001) parallel to the substrate. Hydrogen loading experiments were carried out in two different conditions; namely isothermal and isochronal. Hydrogenation behaviors of the thin films were followed by twopoint probe electrical resistance and optical transmittance measurements, as well as x‐ray diffraction studies. Isothermal hy...
Sol-Gel processing of organically modified ITO thin films and characterization of their optoelectronic and microstructural properties Kesim, Mehmet Tümerkan; Durucan, Caner; Department of Metallurgical and Materials Engineering (2012) Indium tin oxide (ITO) thin films were formed on glass substrates by sol-gel method. Coating sols were prepared using indium chloride tetrahydrate (InCl3•4H2O) and tin-chloride pentahydrate (SnCl4•5H2O) stabilized in organic solvents (acetylacetone and ethanol). First attempt was to synthesize ITO thin films using standard/unmodified coating sols. The effect of calcination treatment in air (300 – 600 °C) and number of coating layer(s) (1, 4, 7 or 10) on optoelectronic properties (electrical conductivity and...
Thickness effects in hydrogen sorption of Mg/Pd thin films Gharavi, Ayshe G.; Akyildiz, Hasan; Öztürk, Tayfur (2013-12-15) Mg thin films with various thicknesses ranging from 50 to 1000 nm capped with Pd have been prepared by thermal evaporation and their hydrogen sorption properties were examined following the electrical resistance change. The study showed that the hydrogenation and dehydrogenation temperatures correlate with the film thickness, thinner films reacting with hydrogen at reduced temperatures. It is concluded that films thinner than 200 nm react fully with hydrogen, while a considerable portion of the thicker film...
Linear viscoelastic properties of polymeric suspensions Bayram, G; Yılmazer, Ülkü; Orbey, N (1999-05-06) Linear viscoelastic properties of a model suspension containing hydroxyl terminated polybutadiene (HTPB) and glass beads with filler concentration up to 30% by volume were investigated by using a Haake parallel disk rheometer. For all the suspensions, it was observed that the rheological properties such as the storage modulus, G', loss modulus, G" and complex viscosity, eta* increases with the filler content, Phi. The relaxation spectra was calculated by using G' and G". The relaxation moduli, G(i)(lambda(i...
Fe-, Ni- and Co-induced crystallization of ge thin films fabricated on different substrates for photovoltaic applications Kabaçelik, İsmail; Kulakcı, Mustafa; Turan, Raşit (null; 2018-07-06) Metal-induced (Fe-, Ni- and Co-) crystallization of amorphous germanium (a-Ge) thin films were investigated by depositing Ge on c-Si (100) and glass substrates by means of electron beam evaporation. The samples were exposed to post-annealing temperatures of 300, 400 and 500 o C for 1 hour (h). The crystal structure of the Ge films was characterized with a Raman spectrum and X-ray diffraction (XRD) measurements. The Raman spectrum of the samples as-deposited and annealed at a temperature of 300 °C gives broa...
