Mesenchymal Stem Cell‐Inspired Microneedle Platform for NIR‐responsive Immunomodulation and Accelerated Chronic Wound Healing

Advanced Materials, EarlyView.
The research demonstrates a Mesenchymal Stem Cell‐inspired microneedle platform (MSCi@MN) that addresses chronic diabetic wounds by combining MSC‐derived extracellular nanovesicles (NV)–DNA conjugates in microneedle tips with photothermal MXene in the patch layer.

A comparative study on cryogenic formability and paint baking property of AA7075 alloy sheets tempered at fast retrogressed and pre-aged conditions

Journal of Materials Research and Technology
Forming at cryogenic temperatures provides a new approach to the formability improvement of 7000-series high-strength aluminum alloys. However, the cryogenic forming process based on solution-treated (W) or peak artificial aged (T6) alloys cannot meet ...

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

Advanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Tuning Pore Size in Porous Graphene Membrane for O2/N2 Separation

Advanced Materials, EarlyView.
Single‐layer graphene membranes featuring N‐functionalized, 0D pores offer a promising platform for O2/N2 separation. The heterogeneity of functional groups at the pore edge is dynamically tunable, enabling precise tuning of the pore limiting diameter and gas transport.
