Understanding the interaction between water and oxides is critical for many technological applications, including energy storage, surface wetting/self-cleaning, photocatalysis and sensors. Here, we report observations of strong structural oscillations of Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3−δ (BSCF) in t...
