Preparation and characterization of hydroxyapatite reinforced with hardystonite as a novel bio-nanocomposite for tissue engineering
Objecttive(s): Despite the poor mechanical properties of hydroxyapatite, its unique biological properties leads we think about study on improving its properties rather than completely replacing it with other biomaterials. Accordingly, in this study we introduced hydroxyapatite reinforced with hardystonite as a novel bio-nanocompositeand evaluate its in-vitro bioactivity with the aim of developi...
متن کاملImproving the mechanical and bioactivity of hydroxyapatite porous scaffold ceramic with diopside/forstrite ceramic coating
Objective(s): Scaffolds are considered as biological substitutes in bone defects which improve and accelerate the healing process of surrounding tissue. In recent years a major challenge in biomaterials is to produce porous materials with properties similar to bone tissue. In this study, the natural bioactive hydroxyapatite scaffolds with nano Diopside /Forstrite coating was successfully synthe...
متن کاملMultiscale Modelling and Mechanical Characterization of Porous Hierarchical Hydroxyapatite
Group G 2 So far, bone surgeons have implemented three techniques for bone repair: autografting (healthy bone tissue taken from the patient’s own body), allografting (healthy bone tissue taken from a donor) and synthetic bone graft substitutes (artificial biomaterial similar to bone). Autografting is considered as the ‘gold’ standard. However the volume of bone that can be safely harvested is l...
متن کاملNumerical Modelling of Porous Radiant Burners Using Full and Reduced Kinetics Mechanisms
The present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (PRB), with their reduced forms. The two most frequently used mechanisms of methane combustion (GRI3.0 and Miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. While the findings of numerical simulation of PRB sho...
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...
