متن کاملPreparation of porous hydroxyapatite scaffolds
In this work, the sintering and grain growth of hydroxyapatite green bodies are analyzed in order to identify the optimum heat treatments for the preparation of porous hydroxyapatite scaffolds. Sintering in air at temperatures ranging between 1100 and 1200 °C yields dense materials with narrow grain-size distributions. The scaffolds are formed by the infiltration of polymer foams with hydroxyap...
متن کاملFabrication of Porous Hydroxyapatite-Gelatin Scaffolds Crosslinked by Glutaraldehyde for Bone Tissue Engineering
In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...
متن کاملSynthesis and Characterisation of CaCO3 (Calcite) Nano Particles from Cockle Shells Using Chitosan as Precursor
Calcium carbonate nano particles were synthesized using precipitation method from cockle shells by employing chitosan as precursor. Synthesized Calcium carbonates were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-Visible and FTIR Spectroscopy. The results were compared with commercial calcium carbonate nano particles. Cockle shells are the potential source...
