NANOSCIENCE
- Tiny particles - 1-100 nanometres across - are called 'nanoparticles'
- Nanoparticles contain around a few hundred atoms
- eg. fullerenes - molecules of carbon,
shaped like hollow balls or closed tubes
- The carbon atoms
are arranged in
hexagonal rings.
- Different fullerenes contain different
numbers of carbon atoms
- The carbon atoms
are arranged in
hexagonal rings.
- 1nm = 0.000 000 001m
- Fullerenes can
be joined together
to form nanotubes
- tiny hollow
carbon tubes, a
few nanometres
across
- All those covalent bonds make
carbon nanotubes very strong.
They can be used to reinforce
graphite in tennis rackets

- A nano particle
has different
properties from
the 'bulk' chemical
it's made from
