A molecular‐bridging heterogeneous interface engineering strategy is introduced to combine a polyhedral oligomeric silsesquioxane (POSS)‐based hard coating with a colorless polyimide (CPI)‐based flexible layer. The robust heterogeneous interface endows the integrated system with the superior properties of both layers and their synergistic ...

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Time‐varying electric fields can activate solid‐state devices such as LEDs and capacitors for energy harvesting and powering in open circuits. The response of solid‐state devices to time‐varying electric fields caused by vibrations can be utilised for smart sensing of human motions and object vibrations.
