“…Probably, a new chemical bond (Sr-O-C) is formed by the reaction between Sr-OH and the hydroxyl end groups of PBSu macromolecular chains. The binding energy of this new peak is 137.6 eV, while the peaks at 132.86 and 134.52 eV more likely correspond to Sr-O bonds of SrHAp nrds [10,18,19]. Regarding WAXD analysis, many interesting results could be concluded studying XRD pattern of PBSu and its nanocomposites.…”

“…nanorods Strontium hydroxyapatite nanorods were synthesized via the hydrothermal method that Zhang et al [10] previously described. In a typical procedure, 3 mmol of Sr(NO 3 ) 2 , 0.5 g of CTAB, and 10 mL of ammonia solution (NH 3 "H 2 O) (used for adjusting the pH value as alkaline solution) were dissolved in 30 mL of deionized water to form solution 1.…”

Novel poly(butylene succinate) (PBSu) nanocomposites containing 5 and 20 wt% mesoporous strontium hydroxyapatite nanorods (SrHNRs) and silica nanotubes (SiNTs) were prepared by melt-mixing. A systematic investigation of the thermal stability and decomposition kinetics of PBSu was performed using pyrolysis-gas chromatography-mass spectroscopy (Py-GC-MS) and thermogravimetry (TG). Thorough studies of evolving decomposition compounds along with the isoconversional and model-fitting analysis of mass loss data led to the proposal of a decomposition mechanism for PBSu. Moreover, the effects of SrHNRs and SiNTs on the thermal stability and decomposition kinetics of PBSu were also examined in detail. The complementary use of these techniques revealed that the incorporation of SiNTs in PBSu does not induce significant effects neither on its thermal stability nor on its decomposition mechanism. In contrast, the addition of SrHNRs resulted in the catalysis of the initial decomposition steps of PBSu and also in modified decomposition mechanisms and activation energies. The evolving gaseous products of PBSu and their evolution pattern in the SiNT nanocomposites were the same as in neat PBSu, while they were slightly modified for the SrHNR nanocomposites, confirming the findings from thermogravimetric analysis.

Biomineralization, the natural pathway of assembling biogenic inorganic compounds, inspires us to exploit unique, effective strategies to fabricate functional materials with intricate structures. In this article, the recent advances in bio‐inspired synthesis of minerals—with a focus on those of calcium‐based minerals—and their applications to the design of functional materials for energy, environment, and biomedical fields are reviewed. Biomimetic mineralization is extending its application range to unconventional area such as the design of component materials for lithium‐ion batteries and elaborately structured composite materials utilizing carbon dioxide gas. Materials with highly enhanced mechanical properties are synthesized through emulating the nacre structure. Studies of bioactive minerals‐carbon hybrid materials show an expansion of potential applications to fields ranging from interdisciplinary science to practical engineering such as the fabrication of reinforced bone‐implantable materials.
