Modulating Iridium Electronic Structure With High‐Valent Metal Doping for Efficient and Durable Acidic Oxygen Evolution Reaction

Advanced Functional Materials, Volume 36, Issue 42, 26 May 2026.
We synthesized a novel IrCuOx/MnO2 heterostructure co‐doped with high‐valent W and Mo atoms, achieving exceptional acidic stability and high mass activity. Owing to the synergistic effects of structural and electronic modulation, cooperative charge redistribution occurs across both the interface and the lattice.

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

Small, Volume 22, Issue 10, 17 February 2026.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...
