Nanoscale Materials Flashcards
1
Q
What is a nanometre?
A
One millionth of a millimetre.
2
Q
What is this the width of?
A
A few atoms
3
Q
What can nanoscale particles do?
A
Occur naturally
Occur as an accidental result of human activity (eg. particulate carbon released when fuels burn)
Be made deliberately by scientists
4
Q
What is it called when Nanoscale Particles are made deliberately by scientists?
A
Nanotechnology
5
Q
What is the difference between Nanoscale particles and larger particles?
A
They have different properties.
6
Q
Why is this?
A
This is often because the smaller particles have a much larger surface area.
