Motivation: Carbon Nano-Foam

NanoScience & NanoTechnologyNanoScience & NanoTechnology

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
