Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Water‐Activated Phospholipid Phase‐Separation Gel as an Immunomodulatory Anti‐Adhesion Barrier for Postoperative Adhesion Prevention

Advanced Healthcare Materials, EarlyView.
A water‐activated phospholipid phase‐separation gel is repurposed as a drug‐free surgical barrier for postoperative adhesion prevention. Propylene glycol promotes rapid lamellar gel reinforcement, prolonged local retention, and tissue coverage, while phosphatidylcholine‐mediated immunomodulation suppresses inflammatory and fibrotic responses. This dual‐

Rubber‐Glass‐Crystal Triple Phase Transition in Polyacrylamide Hydrogels and Environment‐Adaptive Shape Memory Effect

Advanced Materials Interfaces, EarlyView.
By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...
