This study focuses on the biological properties of Ti6Al4V after employing micro-arc oxidation in sodium phosphateand calcium acetate-containing electrolyte with and without addition of silver acetate. After micro-arc oxidation process, structural features of the surfaces were analyzed by using an energy dispersive X-ray spectrometer equipped scanning electron microscope, an X-ray diffractometer and a Fourier transform infrared spectroscope. The micro-arc oxidation process generated multilayer coatings composed of carbonated hydroxyapatite and titanium oxide layers, while addition of 0.001 mol/l silver acetate into the electrolyte caused incorporation of 0.7 wt.% silver into the coating. The antibacterial activity of the coatings was analyzed by using the Streptococcus mutans American Type Culture Collection 25175 strain. The metabolic activity of the multilayers was evaluated in cultures of a human primary osteogenic sarcoma cell line (Saos-2). In short, incorporation of 0.7 wt.% silver in the form of agglomerated particles, mostly around the micropores of the titanium oxide layer, enhanced the antibacterial efficiency of the fabricated coating to some extent without altering the cell proliferation considerably.


Application of the Pippard relations to ammonia near the melting point
Yurtseven, Hasan Hamit (1999-09-01)
This study gives our application of the Pippard relations to the ammonia near its melting point. The Pippard relations between the specific heat C-P, the thermal expansivity alpha(P) and the isothermal compressibility kappa(T), have been established for the ammonia near its melting point. We have obtained that the Pippard relations are valid for the ammonia. We give here an evidence that on the basis of the experimental data the critical transition in this system near its melting point can be considered as ...
Influences of Microemulsion Cross-linking Reaction and Ball-milling on Particle Size Characteristics of Potato and Maize Starches
Zhou, Yu-guang; Li, Dong; Wang, Li-jun; Özkan, Necati; Chen, Xiao Dong; MAO, Zhi-huai (2006-01-01)
In this study, microemulsion cross-linking treatment was used on food grade potato and maize starches for preparing micro starch particles. Laser diffraction technique was introduced to measure the particle size characteristics, including the median particle diameter (d (50)), surface area mean diameter D [3, 2], volume mean diameter D [4, 3] and specific surface area of micro potato and maize starch particles. The volume distributions and number distributions were also analyzed using Mastersizer 2000 Softw...
Production and characterization of activated carbon from hazelnut shell and hazelnut husk
Çuhadar, Çiğdem; Yücel, Hayrettin; Department of Chemical Engineering (2005)
In this study, the pore structures and surface areas of activated carbons produced from hazelnut shell and hazelnut husk by chemical activation technique using phosphoric acid (H3PO4), at relatively low temperatures (300, 400 and 500oC), were investigated. Raw materials were impregnated with different H3PO4 solutions of 30%, 40%, 50% and 60% by weight. To produce activated carbon, acid impregnated samples were heated; at a heating rate of 20 oC/min to the final carbonization temperature and held at that tem...
Bioflocculation of activated sludge: The role of calcium ions and extracellular polymers
Sanin, Faika Dilek (Informa UK Limited, 2000-12-01)
In an attempt to identify the bioflocculation mechanisms, this study examines the role of calcium ions in flocculation of activated sludge. Two calcium specific chelants, ethylenebis (oxyethylenenitrilo)tetraacetic acid (EGTA) and sodium hexametaphosphate (HMT) are used to extract calcium ions. Both chemicals successfully extract the calcium ions from sludge structure, which is confirmed either by an increase in solution calcium concentration or by a decrease in calcium concentration in the sludge solid mat...
Impact modified epoxy/montmorillonite nanocomposites: synthesis and characterization
Isik, I; Yılmazer, Ülkü; Bayram, Göknur (2003-09-01)
Diglycidyl ether of bisphenol A type epoxy resin-polyether polyol-organically treated montmorillonite ternary nanocomposites were synthesized in this study. The effects of addition of polyether polyol as an impact modifier on morphological, thermal and mechanical properties of nanocomposites were investigated by X-ray diffraction, scanning electron microscopy (SENI), differential scanning calorimetry, impact and tensile testing. The results showed that organically treated montmorillonite is intercalated by ...
