Advanced Science, EarlyView.Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...

Advanced Science, EarlyView.Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

Advanced Science, EarlyView.Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...
