Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation
Advanced Science, Volume 13, Issue 18, 27 March 2026.Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.
