Low frequency acoustic properties of bilayer membrane acoustic metamaterial with magnetic oscillator
Theoretical and Applied Mechanics Letters, 2017 A bilayer membrane acoustic metamaterial was proposed to overcome the influence of the mass law on traditional acoustic materials and obtain a lightweight thin-layer structure that can effectively isolate low frequency noise. The finite element analysis (

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2
Advanced Quantum Technologies, EarlyView.Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Small, EarlyView.This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators
Advanced Materials, Volume 38, Issue 13, 3 March 2026.Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.
