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

High‐Performance Recycling Biobased Photopolymers for 3D Printing

Advanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...
