Reconfigurable In–S Coordination in SPAN Cathodes: Unlocking High Sulfur Utilization and Fast Kinetics for Practical Li‒S Batteries

open access: yesAdvanced Science, EarlyView.
An amorphous indium–sulfur complex is embedded in SPAN matrix to create reversible In–S coordination bonds that dynamically break and reform during cycling. This bond reconfiguration actively anchors intermediate polysulfides and accelerates sulfur conversion kinetics, providing simultaneously high active material utilization and durable cycling ...

Unique Color Display via High‐Order Reflectance in 1D Photonic Crystals for Advanced Security Levels in Anti‐Counterfeiting Applications

open access: yesAdvanced Science, EarlyView.
This study demonstrates higher‐order photonic stop bands (PSBs) in humidity‐responsive 1D photonic crystal (PC) films by modulating layer thickness, enabling 2nd‐ and 3rd‐order PSBs with multi‐wavelength reflectivity. Alternating layers of p(2VN‐co‐BPA) and P4QP‐52% produce distinct color shifts and composite colors, advancing PC applications in ...
