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 ...

Record‐High Performance Hyperfluorescent OLEDs Achieved via Electronic Structure Control of Chlorine‐Diversified MR‐TADF Emitters

Advanced Science, EarlyView.
A late‐stage diversification strategy for the benchmark MR‐TADF emitter ω‐DABNA enables precise electronic structure control via chlorine‐activated functionalization. The resulting derivatives achieve tunable emission from 523 to 533 nm with record‐high EQE1000 up to 34.0% and excellent color purity (CIEy = 0.70–0.73), establishing a versatile platform

Electric‐Field Control of Terahertz Response via Spin‐Corner‐Layer Coupling in Altermagnetic Bilayers

Advanced Science, EarlyView.
A spin‐corner‐layer coupling mechanism is proposed in 2D altermagnetic bilayers. Exemplified by NiZrI6, the spin, layer, and topological corner states are simultaneously controlled by an ultralow electric field, enabling active modulation of terahertz absorption, emission, and polarization.

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface

Advanced Science, EarlyView.
A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...

Large‐Scale Synthesis of Monodispersed Perovskite Nanocrystals via Autonomous Continuous Droplet Microfluidics

Advanced Science, EarlyView.
In this work, we propose a novel on‐chip microscale continuous droplet‐in‐flow synthesis (μ‐CDFS) that utilizes zwitterionic ligands to enable large‐scale preparation of perovskite nanocrystals (PNCs) with high emission efficiency and monodispersity.
