Armoring Boron Nitride with Pyrolytic Carbon Layers for Tunable Rigidity and Flexibility

open access: yesAdvanced Science, EarlyView.
By precisely controlling the thickness of the PyC armor, the BN@PyC aerogel achieves a remarkable transformation in mechanical properties, spanning multiple orders of magnitude from flexibility to rigidity, while simultaneously exhibiting versatility, including elastic responsive conductivity, enhanced thermal conductivity, and outstanding ablative ...

Organocatalytic C─O Bond Cleavage and Asymmetric Transformations via [1,3]‐Sigmatropic Rearrangement

open access: yesAdvanced Science, EarlyView.
A direct asymmetric strategy for fulfilling the functional group transfer by aryl ether cleavage and migration is developed, representing the first Brønsted base‐catalyzed asymmetric [1,3]‐sigmatropic rearrangement reaction. The resulting chiral benzofuran products generated through this strategy exhibit significant 3D‐dimensionality and demonstrate ...

Dual‐Modular Hydrogel Microparticles with Precision‐Modulation of Inflammatory Microenvironment Dictate Full‐Thickness Cartilage Regeneration for Osteoarthritis Repair

open access: yesAdvanced Science, EarlyView.
Cartilage injury is a prominent pathological hallmark of osteoarthritis. In this study, we developed a two‐modular hydrogel microparticle system wherein HMP‐A effectively targets the damaged area, while HMP‐B forms an efficient connection with HMP‐A on the cartilage surface.
