“…As expected, no β-Ti was observed in the sample, only α-Ti, due to the slow cooling rate (2 °C/min) allowing for the sample to achieve the equilibrium alpha phase. This thermodynamically stable microstructure is beneficial for long service bone implants as there is less risk of microstructural and therefore property changes over time [ 40 ].…”

Titanium and its alloys have been employed in the biomedical industry as implants and show promise for more broad applications because of their excellent mechanical properties and low density. However, high cost, poor wear properties, low hardness and associated side effects caused by leaching of alloy elements in some titanium alloys has been the bottleneck to their wide application. TiB reinforcement has shown promise as both a surface coating for Ti implants and also as a composite reinforcement phase. In this study, a low-cost TiB-reinforced alpha titanium matrix composite (TMC) is developed. The composite microstructure includes ultrahigh aspect ratio TiB nanowhiskers with a length up to 23 μm and aspect ratio of 400 and a low average Ti grain size. TiB nanowhiskers are formed in situ by the reaction between Ti and BN nanopowder. The TMC exhibited hardness of above 10.4 GPa, elastic modulus above 165 GPa and hardness to Young’s modulus ratio of 0.062 representing 304%, 170% and 180% increases in hardness, modulus and hardness to modulus ratio, respectively, when compared to commercially pure titanium. The TiB nanowhisker-reinforced TMC has good biocompatibility and shows excellent mechanical properties for biomedical implant applications.

The study of the functional living organism through biological phenomena and their piezoelectric and electromagnetic interaction of particles and energy in the functional cells of organ systems that sustain life through homeostasis, and their relationship with the external environment, can be observed as a unique effect called the biopiezoelectromagnetic effect. Research in sciences, combined with the use of innovative technological tools and instruments at scales ranging from the subatomic to the astrophysical, have made it possible to observe, through these individual or combined effects, a phenomenon that is repeated in all structures: the conservation of elemental information. This approach makes it possible to research from the particle to the functional living organism in its environment and vice versa. It is possible to propose theories that link energy, particles and cells and their organised structural complexes within the same framework, analysing the biopiezoelectromagnetic effect and the constant effort to maintain the homeostasis of living organisms in an entropic environment. Biomaterials composed of crystals and quasicrystals promote the piezoelectric effect in living tissue-biomaterial contact. The piezoelectric effect is already known to stimulate and form a fibrocartilaginous bone callus and its subsequent hardening into mature bone but has never been directly associated with homeostasis, osseointegrated implants and biomaterial bonding. The synthesis described by evidence-based experiments over the past centuries is robust to describe the biopiezoelectromagnetic effect as a cascade of events in the functional living organism to maintain homeostasis and its binding properties as the basis of osseointegration and the foundation of biocompatibility.
