Unsaturated Coordination Oxygen in Zn─V─O Vacancy Clusters Enables Superb Zinc Storage Capability

Advanced Science, EarlyView.
Zn3(VO4)2 with Zn─V─O vacancy clusters was synthesized and innovatively applied as cathode material in aqueous Zn‐ion batteries. In‐situ XRD, HRTEM and ab initio molecular dynamics simulations unveil the double reaction mechanism of zinc ions. Adsorption of zinc ions on unsaturated coordination O and H+ on O in ‐VO4 contributes to the main capacity. It

Light‑Driven Propulsion of Graphene Aerogels in Microgravity

Advanced Science, EarlyView.
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).
