Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters
Advanced Functional Materials, EarlyView.An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

A Miniaturized Autonomous Thermomagnetic Generator
Advanced Functional Materials, EarlyView.Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor
Advanced Functional Materials, EarlyView.Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses
Advanced Functional Materials, EarlyView.An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

Advanced Functional Materials, EarlyView.Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...
