What are carbon nanotubes?

carbon nanotubes are hexagonal coal atoms that were converted into tubes. These small cylindrical rollers of pure carbon have useful electrical properties. They have already been used to produce small transistors and one -dimensional copper wire.

have been developed by nanotechnology, a relatively new field that includes building electronic circuits and devices from individual atoms and molecules. Nano means a thousand million units. The nanometer is therefore a thousand million meters. The first experiments of nanofabrication occurred in 1990, when the individual atoms of xenon were placed on a nickel substrate and used to declare the company logo. One of the primary objectives of nanotechnology is to build computer chips and other devices that are thousands of times smaller than they are now. Scientists continued to see F or ways to use them, but as successful applications have the potential to be highly lucrative. Ferrocene is known for its tendency to give up electrons. When exposed to the visible light atomsThe carbon accepted the Ferocene molecule.

This is the first time that carbon nanotubes have been hybridized to undergo electron light transmission. Scientists say these modified carbon nanotubes are the first step in building solar cells using this technology.

The newly discovered ability of carbon nanotubes serves as electrons sources have great potential. One day, carbon nanotubes can replace metal fibers in X -ray machines that tend to burn out quickly. Scientists hope to use them to develop portable X -ray machines for use in airport security, ambulances and customs work.

carbon nanotubes are also of great importance for use in flat panel displays, microwave generators, electricity protection equipment and high intensity lamps.
