Answer 1

-Referred to materials that have single units that exist at the nanoscale.

Question 2

Nanoscale?

Answer 2

• Materials that are between 1-100 nanometers across.

Question 3

Nanometre?

Answer 3

A billionth of a metre.

Question 4

Carbon Nano-materials:

Answer 4

• Carbon nanotubes
• C60 - Buckyballs/fullerenes
• Graphene

Question 5

Nanotechnology?

Answer 5

Is the use of nano-materials to enhance our daily lives.

Question 6

Nanoparticles:

Answer 6

• Specific type of nano-material
• Spherical particles with a diameter of about 1-100nm
• At this size, materials begin to react differently
• Greater surface area so tend to be more reactive

Question 7

Titanium dioxide nanoparticles:

Answer 7

• useful:
• Sunscreen and zincs use nanoparticles of titanium dioxide to block the sunlight.
• The titanium dioxide crystals act like little mirrors that reflect the sunlight.
• Small, so cant be seen with the naked eye.
• Use in antibacterial clothing, antibacterial children toys, and waterproof clothing.
