Proton Selective Nanoporous Atomically Thin Graphene Membranes for Vanadium Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
A scalable high‐performance proton‐exchange‐membrane architecture is demonstrated that integrates monolayer CVD graphene with Ar plasma‐engineered Angstrom‐scale proton‐selective pores, stacked to mitigate non‐selective defects, and interfaced with an ultrathin (≈300 nm) polybenzimidazole layer sandwiched between two Nafion 211 sheets.

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Sustainable Self‐Healing of Perovskite Solar Cells Using Dendrimers as Volatile Reservoirs

open access: yesAdvanced Materials, EarlyView.
Sustainable self‐healing perovskite solar cells (PSCs) are developed through the incorporation of dendrimers with unique molecular structures and appropriately placed functional groups. Notably, even after subjecting ten harsh degradation and recovery cycles, these PSCs maintain 90% of their initial power conversion efficiency (>26%).
