Ultra‐Low Hysteresis Under Large Deformation Enabled by Fast Chains Relaxation in Highly Competitive Dynamic Hydrogen Bond Networks

open access: yesAdvanced Science, EarlyView.
This study demonstrates that incorporating deep eutectic solvent (DES) components tunes the relaxation dynamics of strong hydrogen bonds between polymer segments, rendering them mechanically “invisible” during service conditions (low hysteresis: <3%).

Healable Dielectric Elastomer Actuator With Premature Breakdown Warning Function for Information Transmission Encryption and Human‐Machine Interaction

open access: yesAdvanced Science, EarlyView.
An integral healable dielectric elastomer actuator (ISDEA) with a premature breakdown warning function is prepared based on the combination of electroluminescent dielectric elastomer and transparent compliant electrodes. Several ISDEAs are combined to construct soft anti‐counterfeiting labels and soft intelligent keyboards, expanding their potential ...

Quantum Geometric Engineering of Dual Hall Effects in 2D Antiferromagnetic Bilayers via Interlayer Magnetic Coupling

open access: yesAdvanced Science, EarlyView.
Precise tuning of interlayer magnetic coupling in two‐dimensional bilayers enables control over altermagnetic and PT‐symmetric antiferromagnetic phases. This dual‐phase platform yields two intrinsic Hall responses: a Berry curvature–driven linear anomalous Hall effect and a quantum metric–induced second‐order nonlinear anomalous Hall effect ...

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

open access: yesAdvanced Science, EarlyView.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Cu─X Bonds Regulated Conduction and Polarization Loss in Conductive Metal‐Organic Framework Under Electromagnetic Field

open access: yesAdvanced Science, EarlyView.
A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly
