New Materials

Question 1

what are smart materials?

Answer 1

Smart materials behave differently depending on the conditions

Question 2

give an example of a smart material

Answer 2

Nitinol a shape memory alloy can be bent and twisted like rubber but of bent to much it stays bent. If it is heated above a certain temperature

Question 3

give an example of a smart material

Answer 3

Nitinol a shape memory alloy can be bent and twisted like rubber but of bent to much it stays bent. If it is heated above a certain temperature it goes back to a remembered shape

Question 4

what is a nanoparticle?

Answer 4

A nanoparticle is a very small particle containing a few hundred atoms

Question 5

what is fullerenes?

Answer 5

Fullerenes 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 6

what are nanotubes?

Answer 6

Nanotubes are fullerenes joined together, they are very small hollow carbon tubes, a few nanometres across. The covalent bonds make the tubes very strong.

Question 7

what is nanoscience?

Answer 7

Nanoscience is the new uses of the particles being used for a wide range of purposes

Question 8

give some uses of nanoparticles

Answer 8

1. They could help make new industrial catalysts
2. New cosmetics
3. Stronger, lighter building materials
