Heterointerface Seeding Accelerates Bi0/Bi3+ Phase Conversion for Ultrafast Aqueous Alkaline Batteries

open access: yesAdvanced Science, EarlyView.
An N‐doped carbon‐confined Bi/Bi2O3 heterostructure enables ultrafast and reversible Bi0/Bi3+ phase conversion through heterointerface seeding. The pre‐established Bi/Bi2O3 interfaces provide nucleation‐active sites for heterophase regrowth, while the N‐C shell promotes electron transport and structural stability, overcoming kinetic limitations in ...

Balancing Crystallization Kinetics and Lattice Strain Enables Thermally Stable Slot‐Die‐Coated Narrow‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic

Praseodymium‐Modulated NiFe Layered Double Hydroxide with Enhanced Oxygen Evolution Activity and Extended Durability

open access: yesAdvanced Science, EarlyView.
Pr doping of NiFe‐LDH simultaneously tunes Ni 3d electronics and mesopore architecture. The optimized Ni2Fe0.88Pr0.12‐LDH switches the OER rate‐determining step, delivers 407 mV at 500 mA cm−2, and sustains 2190 h in half‐cell tests. An AEM electrolyzer with this anode operates over 1000 h at industrial current density, offering a durable rare‐earth ...
