Titanium dioxide thin films of nanoporous structures have gained great interest due to their large surface area and high reactivity properties in their applications. One of the methods used to form titanium dioxide nanostructures is anodizing the surface of titanium in F- ion containing electrolytes. Effects of HF concentration (0.1 to 0.5 wt.%), anodizing potential (10 to 30 V) and time (30 to 180 minutes) on the titanium dioxide nanotube formation were investigated by anodically oxidizing Ti6Al4V alloy in this study. Scanning electron microscopy (SEM) images were used to determine the influences of different experimental conditions. In addition, photovoltaic effects from a well-defined cell were used to infer comparative information on the total surface area of nanotubes.

Formation and Characterization of Sub-Micron Inert Particle Embedded Nickel Composite Coatings Yılmaz Tüzün, Özgül; Karakaya, İshak (2017-06-01) Composite coatings have a wide range of application areas requiring improved mechanical and tribological properties. Due to its enhanced properties, Ni-Al2O3 electro-co-deposition rather than pure Ni electrodeposition was investigated. A typical sulfamate bath was used to evaluate the effects of current density on hardness and the amount of deposited Al2O3. It was found that increase in current density increases the hardness and deposited wt.% Al2O3 particles within the parameter ranges covered in this stud...
An Electrochemical Procedure to Form Metal Powders from Recycled Hard Particle Embedded Composite Cutting Tools Altunbasak, Tansu; KUL, MEHMET; Karakaya, İshak (2017-06-01) Used valuable particle embedded composite cutting tools, obtained by powder metallurgy techniques by mixing metallic powders with hard, abrasive particles were electrolyzed for reclamation of metallic powders and valuable particles. The effects of copper ion and sulfuric acid concentrations and pH of the electrolyte, current density and temperature on microstructure of produced copper powders were investigated in detail. Copper powders were characterized by X-Ray diffraction (XRD) and scanning electron micr...
Effect of thermal neutron irradiation on the elastic constants of tourmaline Özkan, H. (Informa UK Limited, 1987-2) The effect of thermal neutron irradiation due to the B10(n, α)Li7 reaction on the elastic wave velocities and the elastic moduli of tourmaline crystals has been studied. Oriented tourmaline samples have been irradiated with thermal neutrons to 7.6 × 1018n/cm2 and the elastic wave velocities determined by ultrasonic measurements. The elastic wave velocities are not affected by thermal neutron irradiation below 8 × 10l7n/cm2, effects starting to appear at approximately 1 × l018n/cm2 with more important decrea...
Synthesis and Characterization of Aluminum Containing Silica Aerogel Catalysts for Degradation of PLA Sivri, Seda; Dilek Hacıhabiboğlu, Çerağ; Sezgi, Naime Aslı (Walter de Gruyter GmbH, 2019-05-01) Aluminum loaded silica aerogel based catalysts were synthesized by impregnation of aluminum into silica aerogel produced using sol-gel method in different aluminum loadings (2.5-15 wt%) to investigate their performances in degradation of polylactic acid (PLA).
FORMATION OF METASTABLE VATERITE CRYSTALS IN A POLYMER MATRIX BY GASEOUS DIFFUSION PITCHER, MICHAEL W.; NESHAT, ABDOLLAH; SEYYIDOĞLU, SEMIH (SciELO Agencia Nacional de Investigacion y Desarrollo (ANID), 2008-6) A composite consisting of a polymer and calcium carbonate has been synthesized by allowing carbon dioxide to diffuse into a poly(ethylene oxide) film containing a Source of calcium ions. The X-ray pattern of the synthetic composite material shows that the least thermodynamically stable polymorph of calcium carbonate, vaterite is the mineral phase which is formed, rather than the most thermodynamically stable calcite phase. This effect has been seen in other reports of crystallization of inorganic phases whi...
