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

Advanced 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 ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

A Dual‐Piezoelectric Metal–Organic Cage/COF Z‐Scheme Heterojunction for Solar‐Mechanical Water Splitting

Advanced Science, EarlyView.
A dual‐piezoelectric Z‐scheme heterojunction is constructed by integrating a piezoelectric metal–organic cage (MOC‐FA3) with a β‐ketoenamine‐linked covalent organic framework (S‐COF). This design enables efficient solar‐mechanical energy conversion, achieving remarkable piezo‐photocatalytic pure water splitting for simultaneous H2 and H2O2 production ...
