Movie S1
In situ field electron emission microscopy video (200 x speed) at 413 K. Oscillations occurring during the hydrogen oxidation reaction over a curved rhodium crystal consisting of nm-sized facets of different crystallographic orientations. The video shows the periodic spreading of reaction fronts which synchronize the oscillations leading to monofrequential behavior.
Movie S2
In situ field electron emission microscopy video (200 x speed) at 433 K. Multifrequential oscillations occurring during the hydrogen oxidation reaction over a curved rhodium crystal consisting of nm-sized facets of different crystallographic orientations. The video reveals that travelling reaction fronts are confined by crystallographic boundaries causing the coupling between regions to cease.
Movie S3
In situ field electron emission microscopy video (200 x speed) at 453 K. Multifrequential oscillations occurring during the hydrogen oxidation reaction over a curved rhodium crystal consisting of nm-sized facets of different crystallographic orientations. The video shows confined regions where the reaction oscillates with their own frequency.
