Nasal Delivery of Engineered Exosomes via a Thermo‐Sensitive Hydrogel Depot Reprograms Glial Cells for Spinal Cord Repair

open access: yesAdvanced Science, EarlyView.
Engineered macrophage‐derived exosomes overexpressing GNA12 and GNA13 reprogram glial cells to promote neuroprotection and neural regeneration following SCI. A chitosan‐based thermosensitive hydrogel enables sustained intranasal exosome delivery, bypassing systemic barriers and enhancing therapeutic efficacy.

Laser‐Induced Coal‐Based Porous Graphene as Anode Toward Advanced Lithium‐Ion Battery

open access: yesAdvanced Science, EarlyView.
A one‐step laser‐induced strategy is reported to prepare porous graphene by utilizing bituminous coal as a precursor (LIG‐B). Laser irradiation transforms coal into graphene, with small molecules from the polymer separating, recombining in gas and forming 3D porous graphene upon quick gas release.

Stable, Highly Conductive, and Strain‐Insensitive Supramolecular Elastomer Composite for Printable Self‐Healing Soft Electronics

open access: yesAdvanced Science, EarlyView.
A printable, self‐healing, stretchable, and highly conductive ink with pressure‐activated adhesive properties is designed by incorporation of liquid metal microparticles and carboxyl‐functionalized carbon nanotubes into a bimodal supramolecular elastomer.

3D Hyperbolic Kirigami Metamaterials With Tunable Auxeticity and Multistability

open access: yesAdvanced Science, EarlyView.
This study proposes a hyperbolic tessellation‐based structure that integrates TPMSs (Triply Periodic Minimal Surfaces, including SP: Schwarz Primitive, SD: Schwarz Diamond, and GY: Gyroid) with rotating rigid polygons, which enables 3D scalable deformation. The structure exhibits auxeticity and multistability, with a maximum volume expansion rate of up
