Zwitterion‐Stabilized Superlattices and Frank‐Kasper Phases in Charged Block Copolymers for Mechanically Robust Dielectric Soft Materials

open access: yesAdvanced Science, EarlyView.
Superlattices formed by the co‐assembly of acid‐functionalized block copolymers and zwitterions exhibit tunable morphologies, transitioning from lamellae to cylinders to Frank‐Kasper phases. Zwitterion interfacial localization enhances dielectric constant, mechanical strength, and thermal stability, making these materials promising for soft electronics

Achieving Anti‐Disproportionation Performance Enhancement and Distorted Inverse‐Disproportionation Reaction Correction of Zr2Fe‐Based Hydrogen Isotope Storage Alloys via Element Substitution

open access: yesAdvanced Science, EarlyView.
Undesirable phase transition behavior and anti‐disproportionation performance limit the hydrogen isotope storage of Zr2Fe alloy. With theoretical screening and experiments, partial Cu/Ni substitutions achieve full reversibility and significantly improve anti‐disproportionation properties.
