Emerging on-chip microcells in electrocatalysis: functions of window and circuit
We discuss current achievements on two basic functions: window and circuit; the former focuses on the active sites, e.g., site identification and monitoring; the latter highlights circuit characteristics, e.g., electrical-field modulation, contact engineering, and in situ conductance.

Dynamic evolution of self-renewal Fe–N–C catalysts for the acidic oxygen reduction reaction
A self-renewal Fe–N–C catalyst with fourfold higher Fe loading and strong FePPc–CNT interactions, showing high ORR activity and stability in acid. A unique self-renewal mechanism sustains activity by exposing fresh Fe–N4 sites over time.
