Apatite-Wollastonite (A-W) ceramics for bio- medical applications were produced by two different processing techniques. In the first 0ne, calcium hydroxyapatite and wollastonite pow- ders were c0mpacted and sintered in the pres- ence of a reactive glass. The second technique was based 0n melt-casting and subsequent heat treatment in which a glass in the MgO- Ca0-Si02-205-F system was homogenized in molten state and then cast to suitable forms. Heat treatments c0nverted the product into a glass-ceramic with predominant crystalline phases as apatite and wollastonite. The micro- structure and the mechanical properties, name- ly flexural strength, cold crushing strength and hardness of the A-W ceramics, were evaluated and c0mpared with those of pure hydroxyapa- tite ceramics. Results showed that the A-W ce- ramics possessed improved mechanical pr0p- erties compared with their pure hydroxyapatite counterparts.

Fabrication and characterization of bilayered tissue scaffolds incorporating bioactive agents for skin tissue engineering applications Aktürk, Ömer; Keskin, Dilek; Bilici, Temel; Department of Engineering Sciences (2015) In this study, it was aimed to fabricate tissue scaffolds from different biological polymers (collagen, silk fibroin and sericin) for skin tissue engineering applications. For this purpose, bilayered scaffolds composed of epidermal (collagen/sericin films) and dermal (collagen sponges, collagen matrices or silk fibroin matrices) layers were produced with different biomaterial fabrication methods. Casting and solvent evaporation (film), lyophilization/freeze-drying (sponge) and dry/wet electro-spinning (micr...
Production and characterization of surface treated biomedical Ti6Al7Nb alloy foams / Bütev, Ezgi; Bor, Şakir; Esen, Ziya; Department of Metallurgical and Materials Engineering (2015) The current study was undertaken to investigate the production and surface processing of biomedical Ti6Al7Nb alloy foams. Space holder method was utilized to manufacture foams with varying porosities around 53.0-73.0 vol. % via evaporation of magnesium from compacted Ti6Al7Nb-Mg powder mixtures. Bioactivities of foam surfaces were further enhanced by obtaining sodium rich phases using NaOH alkali-heat treatment method. Moreover, untreated and surface treated foams were tested in simulated body fluid (SBF) i...
FABRICATION OF MAGNETIC BIOACTIVE GLASS NANOPARTICLES Taşar, Cansu; Ercan, Batur; Department of Metallurgical and Materials Engineering (2022-8-18) Different compositions of bioactive glass nanoparticles have been investigated for various applications, including cancer treatment, drug delivery, bone regeneration, etc. However, targeting of bioactive glass nanoparticles to desired tissues still remains to be a challenge. In this research, sol-gel synthesized bioactive glass and superparamagnetic iron oxide nanoparticles (SPIONs) were combined using two different approaches to obtain magnetic bioactive glass nanoparticle composites. In the first ap...
Structural, mechanical and biological properties of hydroxyapatite-zirconia-lanthanum oxide composites Khoshsima, Sina; Yilmaz, Bengi; Tezcaner, Ayşen; Evis, Zafer (2016-11-01) Novel hydroxyapatite-zirconia-lanthanum oxide composites for bioceramic applications were synthesized and their structural, mechanical and biological properties were studied. Pure HA was produced via precipitation method and the composites were obtained by several fabrication steps: powder milling, mixing, cold pressing and sintering at 1100 degrees C for 1 h. The experimental results indicated that the composites consisted of hydroxyapatite as the main phase with a trace amount of tricalcium phosphate. Cal...
Direct synthesis of hydrogen storage alloys from their oxides Tan, Serdar; Öztürk, Tayfur; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2011) The aim of this study is the synthesis of hydrogen storage compounds by electrodeoxidation technique which offers an inexpensive and rapid route to synthesize compounds from oxide mixtures. Within the scope of this study, two hydrogen storage compounds, FeTi and Mg2Ni, are aimed to be produced by this technique. In the first part, effect of sintering conditions on synthesis of FeTi was studied. For this purpose, oxide pellets made out of Fe2O3-TiO2 powders were sintered at temperatures between 900 °C – 1300...
