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

Applying the Estimand Framework to Non‐Inferiority Trials
Pharmaceutical Statistics, Volume 23, Issue 6, Page 1156-1165, November/December 2024.ABSTRACT Most published applications of the estimand framework have focused on superiority trials. However, non‐inferiority trials present specific challenges compared to superiority trials. The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use notes in their addendum on estimands and sensitivity ...
