Photochemical Fuel Carrier Molecules for Robotic Embodied Energy
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 ...

O2‐Accessible Fe–N4 Active Site Density Boosts Efficient Oxygen Reduction to Fuel‐Cell Level
This study investigates the role of hierarchical nanostructure design in optimizing oxygen mass transport for the oxygen reduction. Using atomically dispersed Fe–N–C catalysts with solid, yolk‐shell, and hollow structures, it demonstrates that the yolk‐shell architecture provides superior O2 accessibility to active Fe–N4 sites.

Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a

Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation
This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.
