Carbon Nanotubes

Breast cancer tumor destruction: nanotubes are used to destroy breast cancer tumors.
Windmill blades: It increases the efficiency of the windmill and helps to produce more electricity at a faster rate.
Filtration: carbon nanotubes can be used to separate particles of size greater than the diameter of carbon nanotubes during filtration through them.
Carbon nanotubes have also been shown to absorb infrared light and may have applications in the IR optics industry.
Aircraft stress reduction: nanotubes are also used in space and aircraft to reduce the weight and stress of the various components working together.
