Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Two‐Dimensional La2CoO4 Perovskite Oxide Enabled by Phonon‐Resonance‐Driven Exfoliation for High‐Performance Gas Sensing

open access: yesAdvanced Science, EarlyView.
Few‐layer La2CoO4 nanosheets are produced via phonon‐resonance‐assisted cleavage of the rock‐salt layers in the Ruddlesden‐Popper structure under the 20 kHz resonance condition, enabling controlled exfoliation into ultrathin sheets. The nanosheets show improved gas‐sensing capability, delivering an 86.67% response to 1 ppm NO2 at room temperature ...
