“…Stokes-Wilson equation (Eq. 9) is widely used to determine the lattice strain (ε) [24] The total peak broadening is represented by the sum of the contributions of crystallite size and strain present in the material. Assuming that the strain present in the material is uniform, the crystal is supposed to have isotropic nature.…”

Synthetic nano hydroxyapatites (HA) have been considered as potential biomaterials for bone tissue engineering applications because of its excellent biological properties. The present work deals with the synthesis of HA nanoparticles from different anion source materials via autoclave assisted hydrothermal method. All the prepared HA nanoparticles were characterized by X-ray diffraction (XRD), Fourier transformation infrared spectra, field emission scanning electron microscopy, energy dispersive spectra and high resolution transmission electron microscopy. The XRD patterns reveal the pure and hexagonal phase structure with smaller crystallite size for HA obtained from various calcium salt precursors. HA particles prepared from nitrate precursors show spherical morphology with 32 nm grain size whereas those derived from the acetate, chloride and egg shell precursors respectively show needle-like, irregular and oval morphology. The effect of different anions on the dielectric properties and alternating conductivity of HA is investigated, as a polarized surface can trigger biological reactions. For the particles obtained from nitrate, acetate, chloride and egg shell precursors respectively give dielectric constant (εʹ) values of 9.96, 13.22, 9.92 and 10.86 at 5 MHz. The εʹ and dielectric loss (εʹʹ) values for the HA nanoparticles decrease with increase in the applied frequency as well. The alternating current conductivity values confirm that the as-synthesized HA samples exhibit insulating behavior. In short this article provides the various applicability of HA particles in optoelectronics and drug delivery.

“…It plays a critical role in the bone calcification process [24]. There are growing evidences that the incorporation of Si into HA enhances the formation of a surface apatite layer in an artificial physiological solution [14,23]. In this regard, Li et al [15] reported that Si film could efficiently slow down the degradation rate of WE43 Mg alloy in simulated body fluid (SBF).…”

Unique nanosized designed ceramic powders, Fedoped hardystonite (Fe-HT) with the chemical composition of Ca 1.85 Fe 0.15 ZnSi 2 O 7 (0.15Fe-HT) and Ca 1.75 Fe 0.25 ZnSi 2 O 7 (0.25Fe-HT), were synthesized by the sol-gel method in order to develop a multifunctional bioactive powder for hyperthermic and tissue engineering applications. Characterization techniques such as X-ray diffraction analysis, transmission electron microscopy, Fourier transform infrared spectroscopy and energy-dispersive X-ray spectroscopy were used to investigate the structural characterization of the obtained powders. The results showed that nanocrystalline single-phase Fe-HT powders were successfully synthesized by sol-gel method. The prepared nanopowders had structural properties such as crystallite size (*53 nm), crystallinity degree (*55 %) and lattice strain (*0.355 %) for 0.15Fe-HT and crystallite size (*40 nm), crystallinity degree (*41 %) and lattice strain (*0.401 %) for 0.25Fe-HT. The obtained Fe-HT nanopowders are expected to be a suitable candidate for tissue engineering and also hyperthermiabased cancer therapy. Graphical Abstract
