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%).

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 ...

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

open access: yesAdvanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed

Direct Observation of Suppressed Optical–Acoustic Phonon Energy Coupling in Supported SWCNT at Cryogenic Temperatures

open access: yesAdvanced Science, EarlyView.
This study quantifies the temperature‐dependent optical–acoustic phonon coupling factor (GOA) in supported single‐walled carbon nanotubes, revealing significant suppression at low temperatures. At high temperatures, GOA increases monotonically and is attributed to intensified anharmonic phonon interactions. This research offers key insights into phonon

Soft and Stretchable Thienopyrroledione‐Based Polymers via Direct Arylation

open access: yesAdvanced Electronic Materials, EarlyView.
π‐conjugated polymers (CPs) that are concurrently soft and stretchable are needed for deformable electronics. This systematic molecular weight study on promising candidates for soft CPs, poly(indacenodithiophene‐co‐thienopyrroledione) (p(IDTC16‐TPDC8)) and poly(indacenodithienothiophene‐co‐thienopyrroledione) (p(IDTTC16‐TPDC8)) found that p(IDTC16 ...
