Advanced Science, EarlyView.A high‐entropy oxide ceramic of (Gd1/2Lu1/2)2(Ti1/3Zr1/3Hf1/3)2O7 is prepared through a molecular synthesis route of pyrolytic solid‐solution reactions. The architectured nanofiber aerogel manifests unprecedented thermomechanical properties, including superelastic compressibility of 98% from −196 to 1500 °C, and thermal superinsulation capacity (24.14 ...

Advanced Science, EarlyView.Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Advanced Science, EarlyView.Inspired by the regulation mechanism of window blinds, this study designs an electromagnetic wave‐absorbing metamaterial. By introducing the magneto‐electric coupling concept and integrating it with an artificial intelligence‐based data‐driven collaborative optimization strategy, the material optimizes impedance matching performance and enhances loss ...
