Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced 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

Photon Recycling Triggered Amplified Spontaneous Emission in MAPbBr3‐Ni(AcO)2 Nanocomposite Waveguides

open access: yesLaser &Photonics Reviews, Volume 19, Issue 10, May 22, 2025.
The reabsorption of photons between small (5 nm) and large (50 nm) MAPbBr₃ nanocrystals (NCs) generates amplified spontaneous emission and random lasing under reduced thresholds (Pth≈1 µJ cm−2) and high‐quality factors (Q ≈10⁴). The device consists of a waveguide structure where the NCs are grown in‐situ within a Ni(AcO)2 matrix.
