Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

Advanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Self‐Assembled Nanoclay Gel With Spheroid MSC‐Derived Exosome Mimetics to Integrate Demineralized Bone Matrix and Noggin‐Targeting miRNA for Synergistic Osteogenesis

Advanced Functional Materials, EarlyView.
We report a versatile nanoclay gel carrier platform that enhances the osteogenic efficacy of demineralized bone matrix (DBM) by integrating nanoclay‐based self‐assembly with cell‐derived exosome mimetics loaded with noggin‐targeting miR‐200c. This design amplifies BMP signaling, thereby promoting DBM‐mediated osteogenesis and offering a promising ...

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
