Nano chemistry

Question 1

What is nano chemistry?

Answer 1

This is the study of the synthesis and characterization of nano materials.

Question 2

What are nano materials?

Answer 2

Nano materials are materials with at least one external dimension in the 1-100nm range.

Question 3

How are nano materials categorised?

Answer 3

Nano materials are categorised based on the number of dimensions the nano material has existing out of the 1-100nm range.

Question 4

List the categories of nano materials.

Answer 4

1. 0-D nano materials
2. 1-D nano materials
3. 2-D nano materials
4. 3-D nano materials

Question 5

What are zero dimension nano materials?

Answer 5

These are nano materials that have all their external dimensions measured in the 1-100nm range.

Question 6

What are one dimension nano materials?

Answer 6

These are nano materials that have one external dimension existing outside the 1-100nm range.

Question 7

What are the sources of nano materials?

Answer 7

1. Natural sources.
2. Anthropogenic sources.

Question 8

Give the examples (preceded with their sources) of nano materials.

Answer 8

Natural sources: wings and skin found in animals

Anthropogenic sources: used in stained glass (different sizes giving the different colours), and nanotubes which are used in bicycles. They are also used to make quantum dots, which are semiconductors.
