Carbon nanotubes are large molecules of carbon that are long and thin and moulded like tubes, around 1-3 nanometres (1 nm = 1 billionth of a meter) in diameter, and hundreds to thousands of nanometers long. As individual particles, nanotubes are 100 times more grounded than-steel and one-sixth its weight. There are various carbon nanotubes properties and applications which take the full favourable position of CNTs interesting properties of aspect ratio, mechanical quality, electrical and thermal conductivity.
There has been substantial practical interest in the conductivity of CNTs. CNTs with particular arrangements of M and N (structural parameters indicating how much the nanotube is twisted) can be highly conducting, and hence can be considered as metallic. Their conductivity has been proved to be a function of their diameter as well as their chirality (degree of twist). CNTs can be either semiconducting or metallic in their electrical behaviour.
Use of silicon coated carbon nanotubes in anodes for Li-ion batteries. They are expecting that the use of silicon can increase the capacity of Li-ion batteries by up to 10 times. However, silicon enlarges during a batteries discharge cycle, which can harm silicon-based anodes. By depositing silicon on nanotubes aligned parallel to each other the researchers hope to prevent damage to the anode when the silicon expands
CNTs have been effectively applied in pharmacy and medicine due to their high surface area that is capable of adsorbing or conjugating with a wide variety of therapeutic and diagnostic agents (drugs, genes, vaccines, antibodies, biosensors, etc.). They have been first proven to be an admirable vehicle for drug delivery directly into cells without metabolism by the body. Then other applications of CNTs have been widely performed not only for drug and gene therapies but also for tissue regeneration, biosensor diagnosis, enantiomer separation of chiral drugs, extraction and analysis of drugs and poisons.
A paper-thin carbon-nanotube film that can heat and solidify the composite materials used in aircraft wings and fuselages, without the need for massive industrial ovens. The film can be trundled onto industrial constituents to deliver uniform, controllable and efficient heating via conduction. When associated with an electrical power basis, the heated film stimulates the polymer to solidify. The method should provide a more direct, energy-saving method for manufacturing virtually any industrial composite, as per to the researchers.
