“…The textural characteristics of the HA and SO 4-HA materials were investigated using N 2 adsorptiondesorption isotherms. Based on IUPAC classification, isotherms for all prepared materials are of type IV, and capillary condensation is accompanied by a narrow hemispherical meniscus (H3), indicating that all the samples have a mesoporous nature [17] (Figure 5). These mesopores are usually formed due to the clustering of primary crystallites [18].…”

The purpose of this study is to synthesize and characterize the mesoporous nanostructure of Hydroxyapatite (HA), evaluate the impact of the addition of sulphate ions (SO 4 2-) on the microstructure properties of HA, and assess the ability of the prepared materials to be used as a carrier for Bovine serum albumin (BSA) protein. This study successfully synthesized 0.07 mole of SO 4 2substituted HA using the reflux microwave-assisted wet precipitation method and fully characterized it using modern techniques. In particular, XRD, XPS, Raman, FESEM, and BET techniques were used to explore the microstructure properties of materials. The results shows that the addition of SO 4 2ions amplified the lattice parameters and surface area of HA, and the particles shape was changed from semi-spherical to rod like shape. Adsorption and desorption of protein molecules were evaluated using BSA protein for 24 h at 37 °C. BSA loading capacity and release behaviours were significantly improved with the incorporation of SO 4 2ions. The SO 4 -HA materials hold a promising future for being used as a carrier for protein molecules.

“…TCPs are naturally present in the processes of both normal and pathological calcifications in human beings, in particular, in the composition of bone and teeth . They are biocompatible and bioactive materials, mainly used in bone graft and teeth replacement, as well as for bone tissue engineering. , Not negligible is also their electrical, optical, magnetic, and catalytic behavior and the potential use as phosphate-based photocatalysts, in particular, for rhodamine B (RhB) contaminated wastewater treatment . Well known as bioceramics, in vitro studies have been also addressed .…”

The scientific interest toward the structural, luminescence, and dielectric properties of tricalcium phosphate (TCP) materials, in particular, the doped TCP-based compounds, is mainly due to their biocompatibility and bioactivity behavior and the increasing number of their applications. In the literature, structural investigations of a doped β-TCP compound are usually carried out by powder diffraction data under the assumption that it has a centrosymmetric whitlockite structure. Recent studies have shown that this assumption is not always fulfilled. For this reason, it is necessary to use methods of nonlinear and dielectric spectroscopy to prove the true symmetry of whitlockite-like phases. This work provides a detailed and comprehensive study on the structural, dielectric, and nonlinear properties of the polycrystalline Tb-and Ho-doped tricalcium phosphates, chemically Ca 9 Tb(PO 4 ) 7 and Ca 9 Ho(PO 4 ) 7 . Their crystal structure was explored using powder X-ray diffraction, adopting an ab initio approach for the structure solution followed by the Rietveld refinement. For Ca 9 Tb(PO 4 ) 7 , the qualitative analysis of the experimental powder X-ray diffraction pattern revealed that the sample was not a single phase. Nevertheless, its crystal structure has been determined by Direct Methods. The presence of the dopant cation was omitted in the solution process by Direct Methods and considered in the successive Rietveld refinement step. The analysis of the occupancies has clarified the Tb 3+ cation distribution in its preferential sites. The same pathway has been followed for the Ca 9 Ho(PO 4 ) 7 sample, which corresponded to a single-phase structure. The dielectric properties of the two doped compounds (Tb 3+ and Ho 3+ ) were also examined, and reversible ferroelectric-paraelectric phase transitions were found at 862 and 872 K, respectively.
