Apatite Formation Ability of Ca2MgSi2O7 Bioceramic: Fariborz Tavangarian1; Sorour Sadeghzade2; Caleb Zolko1; Rahmatollah Emadi2; 1Pennsylvania State University, Harrisburg; 2Isfahan University of Technology
    In this study, akermanite has been synthesized by ball milling technique with subsequent heat treatment of talc, CaCo3 and SiO2 Powders. The results showed that akermanite form through a series of reactions and formation of some intermediate compounds. The produced powder has been uniaxially pressed and the sintered at various temperatures. The mechanical properties of the samples have been evaluated. The produced akermanite samples were soaked in SBF to investigate the bioactivity of the specimens. The results showed that the produced akermanite has the apatite formation ability on its surface and can be a good candidate for biomedical applications.

Biodegradability and Bioactivity of Porous Hydroxyapatite-PCL-hardystonite for Using in Bone Tissue Engineering Application: Fariborz Tavangarian1; Sorour Sadeghzade1; Rahmatollah Emadi2; 1Pennsylvania State University, Harrisburg; 2Isfahan University of Technology
    A study on the bioactivity and mechanical properties of the porous hydroxyapatite-hardystonite-PCL was performed and the results were compared with the non-modify porous hydroxyapatite. Different apatite morphologies were observed in these two modified and unmodified scaffolds. The compression strength, modulus and toughness of the modified scaffolds showed 104, 14 and 38% improvement compared to unmodified scaffolds. This can be ascribed to the main role of thin polymer-ceramic coating layer applied on the surface of hydroxyapatite scaffolds on the mechanical and biological properties. These composite scaffolds showed a great potential to be used for bone tissue engineering application.

Synthesis of Willemite Bioceramic by Mechanochemical Procedure: Sorour Sadeghzade1; Rahmatollah Emadi2; Fariborz Tavangarian1; 1Pennsylvania State University, Harrisburg; 2Isfahan University of Technology
    Willemite is currently recognized as a bio-ceramic material for bone repair and bone tissue engineering applications. In this study, pure willemite powder was fabricated by mechanical alloying method. The starting materials were zinc oxide and silicon oxide. The results showed that pure willemite powder can be produced following 20 h of milling and subsequent sintering at 900 ˚C for 3 h. The obtained willemite powders had crystallite size and particle size in the range of 143-147 nm and 300-500 nm, respectively.
