Dual‐Alloy Exsolution in Fe‐Based Perovskite Anodes for High‐Performance Direct Ammonia Solid Oxide Fuel Cells

open access: yesAdvanced Functional Materials, EarlyView.
Dual FeCo and FeNi alloy nanoparticles are exsolved from a multi‐doped Fe‐based perovskite anode for high‐performance direct ammonia solid oxide fuel cells. The dual‐alloy surface coordinates electronic structure modulation and nanoparticle morphology control, providing abundant reaction sites and complementary catalytic functions for NH3 decomposition,

Multi‐Energy Coupling in Hierarchical Textiles for Photo‐Thermal‐Electric Conversion

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a V‐shaped sandwich evaporator via hierarchical heat‐flow management to resolve constraints on energy utilization and heat allocation in solar evaporation‐thermoelectric systems. The device achieves an evaporation rate of 2.18 kg m−2 h−1 and a peak power density of 224.15 mW m−2, providing an effective strategy for off‐grid solar ...

Architected Bio‐Based Iontronic Skin With Dual‐Mode Pressure and Strain Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based acrylates in combination with an ionic liquid create 3D‐printed ionogels with compositionally tuneable mechanics and ionic conductivity. Gyroid architectures amplify low‐pressure sensitivity while preserving robust strain sensing, enabling dual‐mode detection of pressure and deformation.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

open access: yesAdvanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.
