Rafiee is developing a way to line a
hydrogen vehicle's fuel tank with a one -
atom - thick layer of graphene, essentially a sheet of single - walled carbon nanotubes that have been opened up and
laid flat, so that the tank can better store and release
hydrogen.
Crucially, the pattern was a projection of the spacings of the energy levels in the
hydrogen atom, as
laid out in the wave function, with bright rings where electrons were present and dark lanes where they were not (Physical Review Letters, doi.org/mmz).
