Effect of Dilute Gelatine on the Ultrasonic Thermally AbstractA series of nano hydroxyapatite-gelatin composites with different dilute solutions of gelatin concentrations were synthesized by a thermally assisted low power ultrasonic irradiation method.The gelatine hydroxyapatite, (Gel-HAP) nanoparticles were prepared using Ca(NO 3 ) 2 and KH 2 PO 4 in the presence of gelatine in an aqueous solution. The synthesised products were heat treated between 100°C and 400°C. The effect of the addition of gelatin on the nucleation and growth of synthesised nano HAP was investigated. Characterisation was performed using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FT-IR). The characterisation results indicate that gelatin has been appended to the nano HAP forming regular spherical shaped crystals of nano sized Gel-HAP.

Discussion on the Peak Shift of Α-Ti Phase in Tio2 Nanostructured Coatings on Ti-6Al-4V Alloy

“…To achieve biocompatibility, osteoconductivity, and osseointegration, it is necessary to modify the surface of Ti-6Al-4V alloy by developing hydroxyapatite (HAp, Ca10(PO4)6(OH)2) coating on its surface [3][4][5][6][7][8][9]. HAp composite materials, which is a bonding interface to stimulate bone apatite and collagen production, improves bone anchorage due to osseointegration for long periods [10]. J.…”

Synthesis and characterization of hydroxyapatite-gelatine composite materials for orthopaedic application

“…There are various methods of HA-gelatine composites preparation [11e17]: ultrasonic thermally assisted synthesis of nano hydroxyapatite [12], biomimetic precipitation [13]. But still the most popular method is hydroxyapatite precipitation into a gelatine gel or a matrix [14,15].…”

Fabrication of MgAl2O4 Spinel Scaffolds and Sonochemical Synthesis and Deposition of Hydroxyapatite Nanorods

“…Furthermore, deposition processes such as biomimetic deposition and electrodeposition techniques are also employed . However, studies on sonochemical deposition of HAp formulation is limited and also to the best of authors knowledge attempts to simultaneously synthesis and deposit HAp on spinel foams through sonochemical process have not been studied yet . In the present investigation, the spinel foams prepared through polymeric sponge replication processing were placed in the stoichiometric precursor solution of HAp.…”
