“…The X-ray photoelectron spectroscopy (XPS), XRD, and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) characterizations of the nanoparticles have been thoroughly studied in the previous work [34]. The TEM images for (a) HA, (b) ZnHA, and (c) ZnHA-rGO nanoparticles are presented in Figure 1.…”

“…The difference in ionic radius between Zn 2+ and Ca 2+ can distort the PO4 3− structure [40,41]. Moreover, the interaction between the rGO atoms with the surface atoms of HA nanoparticles can affect the structure of PO4 3− [34]. Figure 3a shows the Raman spectra for HA, ZnHA, and ZnHA-rGO nanoparticles.…”

“…In case of the projection onto (100) plane, there are possibly at least two cross-sections shown in Figure A5 e,g ( Appendix A ). According to [ 41 ], the apatite structure can be considered as build of layers parallel to ac showing the sequence –B–A-A–B– along [ 10 ], where A = Ca 3 (PO 4 ) 2 and B = Ca 4 (PO 4 ) 2 (F,OH) 2 (compare Figure A5 f,h, Appendix A ). In Figure A5 e ( Appendix A ), the layers A-A (PO 4 -rich), shown in projection onto (100), are composed of parallel and alternating strips of Ca 2+ and PO 4 3− ions.…”

“…Due to its structural similarity to biological bone, visible biocompatibility, and bioactivity, HAp has been applied in medicine and dentistry in several forms: as dense sintered ceramics; porous forms; granules; and coatings of metal implants [ 8 , 9 , 10 ]. The shape of HAp crystallites is highly anisotropic, with at least two types of crystal faces: (100) and (101), and rarely (001), exhibiting different distributions of electrostatic potential, different interactions with water, and different adsorptions of biomolecules [ 11 ].…”
