Bioresorbable Plates and Screws for Clinical Applications: A Review
Journal of Healthcare Engineering, Volume 3, Issue 2, Page 243-260, 2012., 2012 Bioresorbable implants are being widely used for fracture fixation in orthopaedic surgery and the market is expanding rapidly worldwide. Bioresorbable materials slowly dissolve in the human body, such that a second operation to remove the synthetic material is not needed. Bioresorbable implants have expanded the armamentarium of the surgeon, especially

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite
Advanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication
