Bone, as a mineralized composite of inorganic (mostly carbonated hydroxyapatite) and organic (mainly type I collagen) phases, possesses a unique combination of remarkable strength and toughness. Its excellent mechanical properties are related to its hierarchical structures and precise organization of the inorganic and organic phases at the nanoscale: Nanometer-sized hydroxyapatite crystals periodically deposit within the gap zones of collagen fibrils during bone biomineralization process. This hierarchical arrangement produces nanomechanical heterogeneities, which enable a mechanism for high energy dissipation and resistance to fracture. The excellent mechanical properties integrated with the hierarchical nanostructure of bone have inspired chemists and material scientists to develop biomimetic strategies for artificial bone grafts in tissue engineering (TE). This critical review provides a broad overview of the current mechanisms involved in bone biomineralization, and the relationship between bone hierarchical structures and the deformation mechanism. Our goal in this review is to inspire the application of these principles toward bone TE.

“…In the presence of background ions, water-water interactions would be different with respect to pure water, due to the electrostatic environment related to background ions present in the solution. The stronger the background ion-water interactions (X − -H 2 O and M + -H 2 O) resulting from higher charge density and lower ionic size, the higher the activation energy barrier of expelling water from the solvation shells of background ions [24,61,62]. Consequently, the more structured the water network, the lower the activation energy required to break water-water interactions in the presence of background ions (E BCKG_0 ).…”

“…Consequently, the more structured the water network, the lower the activation energy required to break water-water interactions in the presence of background ions (E BCKG_0 ). Restricted water movement at the PNC-solution interface (i.e., Li + or Cl − ) would hinder phase separation, because desolvation would be the rate-limiting step for nucleation [10,61]. Also, the presence of background ions (M + and X − ) influences the required energy to strip off a water molecule from the solvation shell of a structure-forming ion (such as Ca 2+ and CO 3 2− ) and/or from PNC solute species.…”

Hydration Effects on the Stability of Calcium Carbonate Pre-Nucleation Species

et al. 2017

Recent experimental evidence and computer modeling have shown that the crystallization of a range of minerals does not necessarily follow classical models and theories. In several systems, liquid precursors, stable pre-nucleation clusters and amorphous phases precede the nucleation and growth of stable mineral phases. However, little is known on the effect of background ionic species on the formation and stability of pre-nucleation species formed in aqueous solutions. Here, we present a systematic study on the effect of a range of background ions on the crystallization of solid phases in the CaCO 3 -H 2 O system, which has been thoroughly studied due to its technical and mineralogical importance, and is known to undergo non-classical crystallization pathways. The induction time for the onset of calcium carbonate nucleation and effective critical supersaturation are systematically higher in the presence of background ions with decreasing ionic radii. We propose that the stabilization of water molecules in the pre-nucleation clusters by background ions can explain these results. The stabilization of solvation water hinders cluster dehydration, which is an essential step for precipitation. This hypothesis is corroborated by the observed correlation between parameters such as the macroscopic equilibrium constant for the formation of calcium/carbonate ion associates, the induction time, and the ionic radius of the background ions in the solution. Overall, these results provide new evidence supporting the hypothesis that pre-nucleation cluster dehydration is the rate-controlling step for calcium carbonate precipitation.

“…They remain relatively stable in the phosphatecontaining solution in the absence of a nucleation-inducing surface. In the presence of a nucleation-inducing surface, aggregation of the prenucleation clusters leads to their densification near the cement surface, producing a 'dense liquid' CaP-rich phase [43]. Coalescence of the densified prenucleation clusters subsequently results in the deposition of globular amorphous calcium phosphate on the set cement surface (Fig.…”
