Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

open access: yesAdvanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Atomic‐Level Dual‐Cation Engineering Enables High‐Performance Na4VMn(PO4)3 Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability
