DEFINATION
particles that have at least one dimension that measures 100 nanometers or less are called nano particles.
The properties
of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive to some other molecules.
Nanoparticles are used, or being evaluated for use, in many fields. The list below introduces several of the uses under development.
Ex.- carbon nanotubes,fullerens etc
Properties of nano particles
1. Nano particles have size of 10^-9 m
2. Tools of nanotechnology permit observation and meniculation to form new structures
3. The developed nano particles have mechanical, electrical, magnetic &other properties are not not possible in normal materials
Nanoparticle Applications
1. In modern times the nanotechnology is a very important and applicable tool of science and technology
2. Nanotechnology is used in food science in agriculture,in food sefty,and bio security.
3. It is used in energy resources like storeage conservation manufacturing.
4. Nano particles are used in paint and casting materials
5. Carbon nanotubes are used for febricating field emitter for flat panel,full colour display like t.v. and computers
Transparent nano particles of ZnO asbsgos ultraviolet light and it is used in modern transparent and highly effective sun glasses
6. Nano particles Titanium dioxide (Ti2O3) are key ingredients in solar panels.
