15 صفحه اولEffect of Graphene Oxide Nanoparticles Addition on Mechanical and Biological Properties of Calcium Phosphate Cement
In the present study, we have evaluated the effects of graphene oxide (GO) addition on the physical-mechanical-biological properties of calcium phosphate cement (CPC). The in vitro cellular responses of MG63 and in vivo tissue responses after the implantation of CPC/GO in parietal bone defects of wistar rats were also investigated. The brushite calcium phosphate cements were prepared by mixi...
متن کاملTHE EFFECT OF RAW MATERIALS CONCENTRATION ON HYDROXYAPATITE POWDER CHARACTERISTICS AND SINTERING BEHAVLOR
Ultrafine hydroxyapatite (HAp) powders with crystallite size in the range of 10-90 nm were synthesized by chemical precipitation process using Ca(OH)2 and H3PO4 solutions as starting materials. Molar ratio of Ca/P=1.68 was kept constant throughout the process and alkaline condition for the reaction was maintained using ammonium hydroxide. The role of raw material concentration on HAp crystallit...
