              Motivation: Carbon Nano-Foam
The creation of a molecular structure involves “atom-to-atom” “assembly” under
appropriate physical conditions and rate.
     Laser ablation is one possible avenue to create man-made materials.
     E.g., from graphite:
      Fullerenes and Carbon Nanotubes
      Amorphous Carbon (Films)
     Carbon Nano-Foams

           Granular low density nanofoam:
           TEM image shows the free-
           standing fractal structure of the
           carbon foam. The foam consist of
           a network of interconnected
           carbon clusters of ~ 6nm in size
