Sub‐1000 °C Sintering of Protonic Ceramic Electrochemical Cells via Microwave‐Driven Vapor Phase Diffusion

open access: yesAdvanced Materials, EarlyView.
A transformative microwave‐driven vapor‐phase sintering strategy enables densification of proton‐conducting electrolytes at 980 °C, reducing the sintering temperature by over 500 °C and addressing a major bottleneck toward PCEC manufacturing. Abstract Protonic ceramic electrochemical cells (PCECs) hold significant promise for efficient power generation

Magnetically “Programming” Cobalt‐Doped Iron Oxide Nanoparticles for Localized Induction Heating: Triggering a Collective Effect of Magnetic Moment Alignment on Demand

open access: yesAdvanced Materials, EarlyView.
This study demonstrates enhanced induction heating in cobalt‐doped iron oxide nanoparticles via specific pre‐magnetization, induced by the pre‐alignment of magnetic moments. By correlating Co content with magnetic properties, the research highlights how magnetic pre‐programming enables localized, on‐demand debonding in composites.

Stimuli‐Responsive Low‐Frequency Terahertz Absorption ON‐OFF Switchability in Spin‐Crossover Material

open access: yesAdvanced Materials, EarlyView.
A switchable Fe(II)–Hg(II) coordination polymer exhibits reversible ON‐OFF terahertz (THz) absorption through temperature‐ and light‐induced spin‐crossover. The material shows strong, tunable THz responses linked to phonon modes around Fe(II) centers, supported by spectroscopic measurements and calculations.
