Effect of Annealing Temperature on Microstructure and Dry‐Sliding Behavior of Powder Bed Fusion–Laser Beam Ti6Al2Sn4Zr6Mo Alloy

Advanced Engineering Materials, EarlyView.
Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

Late Dislocation Following Total Hip Arthroplasty: Spinopelvic Imbalance as a Causative Factor

Journal of Bone and Joint Surgery. American volume, 2018
Background: Late dislocations after total hip arthroplasty (THA) are challenging for the hip surgeon because the cause is often not evident and recurrence is common.

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.
