Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

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.

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

APTES‐Mediated Ti‐Squarate MOF/n‐GaN Nanowire Photoanodes for Efficient Photoelectrochemical Water Splitting

Advanced Functional Materials, EarlyView.
The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement
