Hydrogen–metal surface interactions play an important role in energy technologies and metal corrosion, but a thorough understanding of these interactions at the nanoscale remains elusive due to detection limits and the volatility of pure hydrogen. Here, the authors use transmission electron microscopy to show that hydrogen adsorbs directly at the (0001) surfaces of hexagonal helium bubbles within neutron irradiated beryllium.
