“…The coefficient of thermal expansion as well as the modulus of elasticity of titanium closely resembles those of human bone, which in turn significantly reduces the potential for the patient receiving titanium implants to experience stress shielding, as the loads will be comparatively well distributed across the skeletal structure [ 92 , 93 ].…”

Commercially pure titanium and titanium alloys have been among the most commonly used materials for biomedical applications since the 1950s. Due to the excellent mechanical tribological properties, corrosion resistance, biocompatibility, and antibacterial properties of titanium, it is getting much attention as a biomaterial for implants. Furthermore, titanium promotes osseointegration without any additional adhesives by physically bonding with the living bone at the implant site. These properties are crucial for producing high-strength metallic alloys for biomedical applications. Titanium alloys are manufactured into the three types of α, β, and α + β. The scientific and clinical understanding of titanium and its potential applications, especially in the biomedical field, are still in the early stages. This review aims to establish a credible platform for the current and future roles of titanium in biomedicine. We first explore the developmental history of titanium. Then, we review the recent advancement of the utility of titanium in diverse biomedical areas, its functional properties, mechanisms of biocompatibility, host tissue responses, and various relevant antimicrobial strategies. Future research will be directed toward advanced manufacturing technologies, such as powder-based additive manufacturing, electron beam melting and laser melting deposition, as well as analyzing the effects of alloying elements on the biocompatibility, corrosion resistance, and mechanical properties of titanium. Moreover, the role of titania nanotubes in regenerative medicine and nanomedicine applications, such as localized drug delivery system, immunomodulatory agents, antibacterial agents, and hemocompatibility, is investigated, and the paper concludes with the future outlook of titanium alloys as biomaterials.

“…[1][2][3] Yet, homogeneity at atomic scales is not always desirable, with notorious examples in the preparation of a large variety of thin-film composites, for example, for mechanical applications, [4] the fabrication of Zintl phases, [5] the production of high entropy alloys, [6] strained controlled TiAlN thin films, [7] or Nb segregated phases in Nb-Ti alloys for better control of the material's thermal expansion. [8] In these and many other examples in the literature, the appearance of chemical composition inhomogeneities in the material may lead to optimized functionalities. [9][10][11] An interesting case of emerging interest in this context is the fabrication of nanostructured Janus-type thin films, which, prepared by MS from several targets, are characterized by a nanocolumnar morphology with different compositions at their sides.…”

We demonstrate the existence of stoichiometric variations at the nanoscale when growing nanocolumnar SiO x thin films by reactive magnetron sputtering deposition at oblique angles. Results show stoichiometric variations in the range 0.3 < x < 1.3 when growing a SiO 0.5 thin film. This agrees with results from a numerical growth model that obtains a shift of the stoichiometry in all nanocolumns from lower values at the side facing the Si target to higher values at the opposite side. The different momentum distribution of the gaseous reactive and sputtered species results in preferential incorporation of the latter at a particular side of the nanocolumns. The general occurrence of this mechanism during the reactive magnetron sputtering deposition of substoichiometric thin films at oblique angles is discussed.

“…Taking advantage of compositional fluctuations of the β-stabilizer, a transitory phase with the same orthorhombic structure as αʺ martensite forms in a diffusion-controlled process upon heating [13]. Currently, there is no clear consensus in the literature on the naming of this orthorhombic phase, which has been reported in different β-stabilized Ti-alloys [14][15][16][17][18][19]. It was labeled αʺiso, Oʹ, and 'orthorhombic crystal' by different authors.…”
