High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening

open access: yesAdvanced Materials, EarlyView.
Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.

Four-Layer Structural Reconstruction for Recurrent Anterior Shoulder Dislocation

open access: yesArthroscopy Techniques, 2020
Recurrent anterior shoulder dislocation is always combined with glenoid and capsule-labrum deficiency. To address all these deficiency in a single operation, we developed a 4-layer structural reconstruction technique at the anterior side of the shoulder,

Simultaneous Multi‐Resonant Thermally Activated Delayed Fluorescence and Room Temperature Phosphorescence from Biluminescent Nitrogen‐Containing Indolocarbazoles

open access: yesAdvanced Science, EarlyView.
An extremely rare type of organic biluminescent emission is reported that consists of delayed emission resulting from both the fluorescence (multi‐resonance thermally activated delayed fluorescence) and phosphorescence spectra at room temperature, and the lifetimes of the two processes exhibit opposing dependence with temperature.

Magnesium‐Mediated Electrochemical Synthesis of Ammonia

open access: yesAdvanced Science, EarlyView.
This study demonstrates a lithium‐free, magnesium‐mediated electrochemical process for converting nitrogen (N₂) to ammonia (NH₃) under mild conditions. Using abundant materials, the system achieves ≈27% Faradaic efficiency at lower voltages than Li‐ and Ca‐mediated systems.
