Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

open access: yesAdvanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Encapsulating Textiles with Dynamic Covalent Networks for Sustainable and Efficient Oil Spill Cleanup

open access: yesAdvanced Science, EarlyView.
By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...
