When an unusual response to stimulus like this occurs, it isn't always obvious how to exploit it, but 'twas doubtless the same is early semiconductor work, early superconductor work, and certainly early bucky ball/nanotube work. At school I was taught about graphite and diamond and that's it. The other forms did not exist as far as we knew. Now look, were starting to find applications we never imagined before.
Discover a previously undocumented interaction, optimise it, play with it, make it repeatable, then leave it for the engineers to apply it in the world.
