Crystallite size study of nanocrystalline hydroxyapatite and ceramic system with titanium oxide obtained by dry ball milling

Eggshell-Derived Hydroxyapatite

“…[18][19][20]23 Eggshell-derived hydroxyapatite seems to be promising graft material with excellent properties for grafting [18][19][20]23 with viable various production techniques. [25][26][27][28][29][30][31][32][33][34][35] Lack of disease transfer risks, biocompatibility, and ease of use makes EHA a viable choice as regenerative material. Eggshell-derived hydroxyapatite is hydrophilic in nature, absorbed by body fluids and blood, so that handling becomes easy for placing it in the surgical site.…”

Spectroscopy studies of NiFe2O4 nanosized powders obtained using coconut water

“…Initially, the solution was annealed at 100 • C for 24 h [26][27][28], and then was heat-treated at: (A) 400 • C-QRT;(B) 800 • C-QRT; (C), 1000 • C-QRT; (D) 1200 • C-QRT, during 4 h and (E) 1200 • C-ART, during 1 h, to completely oxidize the salts and promote the crystallization. QRT is the acronym for quenching back to room temperature and ART is for the samples for annealed to room temperature.…”

“…The structural characterization of all the samples was carried out by the X-ray diffraction (XRD) technique at room temperature, using powdered samples, in a Philips X'Pert system, with a K␣ radiation ( = 1.54056 Å) at 40 kV, and 30 mA, with a step of 0.02 • and a time per step of 1 s. The average grain size (Lc) was obtained from the measured width of the samples diffraction curves using the Debye Scherrer's equation [27]. The magnetization and the 57 Fe Mössbauer Spectra (MS) have been already studied by Silva et al [24].…”

Structure–property relationships of iron–hydroxyapatite ceramic matrix nanocomposite fabricated using mechanosynthesis method

“…A work on CaP-Ti composite reported by Silva et al [16] showed that increased in milling time has resulted in smaller grain size composite without reaching its melting point. This method also …”
