Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-73457-7 Using in situ Bragg coherent X-ay imaging and TEM analyses, the authors show Ru-doped perovskite exsolution occurs selectively at mixed dislocations that propagate from particle interiors as mobile vehicles, dynamically transporting Ru to surfaces.
