Photochemical Fuel Carrier Molecules for Robotic Embodied Energy

open access: yesAdvanced Materials, EarlyView.
We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Low‐Dimensional MOF Nanoarchitectonics: Progress in MOF‐2D Material Hybrid Architectures for Energy Conversion and Storage

open access: yesAdvanced Materials, EarlyView.
This review highlights the integration of metal‐organic frameworks (MOFs) and two‐dimensional (2D) materials through dimensional interface engineering. By addressing intrinsic limitations like poor conductivity and agglomeration, these hybrid architectures optimize interfacial charge and mass transport.
