Zhao Liu et al.

Summary: The exsolution of metallic nanoparticles from oxide supports provides a new approach for designing high-performance materials. In this study, Pd nanoparticles with an average size of 100 nm were homogeneously exsolved in compressively strained La0.6Sr0.4Fe0.9Pd0.1O3-delta thin films. The exsolved nanoparticles showed a more stable electrical response in redox cycling, attributed to their dynamic nature.
