Carbon can form diamond, nanotubes, or the nanoscale spheres called buckyballs, as well as several other structures. Now a team has produced what they call carbon honeycomb, a structure that appears to have a huge gas-storage capacity. By slightly altering a common fabrication method, the researchers created what appears to be a 3D honeycomb built from the carbon sheets known as graphene. This structure might be used as a light, energy-efficient fuel storage container for hydrogen fuel cells.
