Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

open access: yesAdvanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Interfacially Coupled and Synergistic Effect of Ag/Co3O4‐C Nanocomposites for Enhanced Oxygen Reduction (ORR) and Evolution (OER) Reaction

open access: yesAdvanced Science, EarlyView.
Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...

Quasi‐Antipolar Nanoclusters Driven Superior Energy Storage in High‐Entropy Relaxor Ferroelectrics

open access: yesAdvanced Science, EarlyView.
Quasi‐antipolar nanoclusters are engineered in lead‐free NaNbO3‐based high‐entropy relaxors that weaken polar nanoregion coupling and induce distinct ferroelectric transition under high fields to enable desirable polarization response. This breakthrough system achieves ultrahigh recoverable‐energy‐density (≈18.3 J cm−3), efficiency (≈91.5%), and ...
