Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators
Advanced Materials, EarlyView.Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide
Advanced Materials, EarlyView.This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...
