Exploring the potential of intermetallic alloys as implantable biomaterials: A comprehensive review.

This review delves into the utilization of intermetallic alloys (IMAs) as advanced biomaterials for medical implants, scrutinizing their conceptual framework, fabrication challenges, and diverse manufacturing techniques such as casting, powder metallurgy, and additive manufacturing. Manufacturing techniques such as casting, powder metallurgy, additive manufacturing, and injection molding are discussed, with specific emphasis on achieving optimal grain sizes, surface roughness, and mechanical properties. Post-treatment methods aimed at refining surface quality, dimensional precision, and mechanical properties of IMAs are explored, including the use of heat treatments to enhance biocompatibility and corrosion resistance.

Mixed oxide nanotubes in nanomedicine: A dead-end or a bridge to the future?

Nanomechanical properties, wear resistance and in-vitro characterization of TaO nanotubes coating on biomedical grade Ti-6Al-4V.

Tantalum pentoxide nanotubes (TaO NTs) can dramatically raise the biological functions of different kinds of cells, thus have promising applications in biomedical fields. In this study, TaO NTs were prepared on biomedical grade Ti-6Al-4V alloy (Ti64) via physical vapor deposition (PVD) and a successive two-step anodization in HSO: HF (99:1)+5% EG electrolyte at a constant potential of 15V. To improve the adhesion of nanotubular array coating on Ti64, heat treatment was carried out at 450°C for 1h under atmospheric pressure with a heating/cooling rate of 1°Cmin.

Characterization of nickel-doped biphasic calcium phosphate/graphene nanoplatelet composites for biomedical application.

The effect of the addition of an ionic dopant to calcium phosphates for biomedical applications requires specific research due to the essential roles played in such processes. In the present study, the mechanical and biological properties of Ni-doped hydroxyapatite (HA) and Ni-doped HA mixed with graphene nanoplatelets (GNPs) were evaluated. Ni (3wt.
