Movie S1
Animation of the cryo-transfer procedure Animation of the cryo-transfer process, including the glove box, the suitcase, the loadlock and the gate valves.
Movie S2
APT supplementary data â€" animation of the dislocations in Figure 4 Animated 3D reconstruction showing deuterium atoms (red), iron atoms (grey) and a 2% carbon isosurface (blue) showing the linear morphology of the carbon-decorated dislocations.
Movie S3
APT supplementary data â€" animated slice view of the dislocations in Figure 4 An animation in which a 5 nm slice view moves from the back to the front of the dataset showing carbon (blue), deuterium (red) and a small fraction of the iron (grey). Both the deuterium and the carbon are associated with the dislocations.
Movie S4
APT supplementary data â€" animated slice view of the GB region in Figure 4 An animation in which 5 nm slice view of the data along the z plane moves from the top to the bottom of the grain boundary region, showing carbon (blue), deuterium (red) and a small fraction of the iron (grey). Both the deuterium and the carbon are associated with the dislocations, but the amount of segregation varies across the plane of the grain boundaries.
