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 ...
Organocatalytic resolution of racemic alpha azido ketones Canbolat, Eylem; Demir, Ayhan Sıtkı; Department of Chemistry (2012) Chiral cyclic alpha azido ketones are very important compounds in organic chemistry. Because, the reduced forms of them are amino alcohols and these amino alcohols are interesting compounds for their biological activities. They have some pharmaceutical activities such as: potassium channel open up properties, treatment of central nervous system, antihypertensive properties, the agent of dopamin receptor activator, hypolipemic agent and dopamine agonist. These types of compounds have highly acidic alpha-prot...
Performance evaluation of Cappadocian tuffs treated with alcohol dispersion of calcium hydroxide nano-particles Çalışkan, Berkay Barış; Tavukçuoğlu, Ayşe; Saltık, Emine Nevin; Department of Building Science in Architecture (2022-12-08) In this study, the effect of treatment with alcohol dispersion of calcium hydroxide Ca(OH)2 nanoparticles on controlling excessive water absorption and capillary water suction properties of Cappadocian tuffs was investigated extensively. For this purpose, two tuff types, Göreme Rock (CYT) and Cappadocian Rose (CPT), obtained from a quarry near Avanos-Nevşehir, were examined. Laboratory tests were conducted concerning their basic physical, hygric, mechanical, microstructural, and mineralogical properties bef...
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...
Nano calcium phosphates doped with titanium and fluoride ions: sinterability and stability of phases Güngör Geridönmez, Serap; Evis, Zafer; Department of Engineering Sciences (2012) The purpose of this study was to synthesize calcium phosphates doped with titanium and fluoride ions in different combinations. Pure and doped calcium phosphates were synthesized by a precipitation method. The synthesized materials were sintered at 1100ºC and 1300ºC for 1h. The ceramics were characterized by density measurements to determine the effect of sintering temperature. Presence of phases and bonds were characterized by XRD diffraction and FTIR spectroscopy. Grain sizes of the samples were obtained ...
