Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

open access: yesAdvanced Science, EarlyView.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

Outstanding 1200 °C Oxidation Resistance in a Novel Multi‐Principal Element Alloy via Lattice Distortion‐Induced Diffusion Suppression

open access: yesAdvanced Science, EarlyView.
The unique lamellar structure of the eutectic alloy promotes selective oxidation of Al initially, while lattice distortion‐induced diffusion suppression slows oxide growth during steady state. Combining these strategies, a Multi‐Principal Element Alloy with excellent oxidation resistance at 1200℃ was designed.

Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...
