Nano (New) Materials

Question 1

Smart Materials:

Answer 1

A material whose properties change depending on the conditions (e.g. temperature, pressure). An example of a material would be Nitinol - a shape memory alloy. It will return to it’s original shape at a certain temperature

Question 2

Nanoparticles:

Answer 2

1-100 nanometres across. Nano means really small. Nanoparticles contain roughly a few hundred atoms.

Question 3

What do nanoparticles include?

Answer 3

Fullerenes - these are 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.

Question 4

EXTRA

Answer 4

Fullerenes can be joined together to form nanotubes. All those covalent bonds make carbon nanotubes very strong.
