Nanotubes-Currently, many different types of carbon nanotubes have been discovered since they were first discovered by Sumio Iijima. Also, the first mixture of nanotubes was discovered in 1993 by Robert E. Smalley at Rice University and since then different mixtures have been created.
Materials-so far, there have been some materials such as nano-powders and nanotubes that have been created by nanotechnolgy companies.
Nano Powers Industries currently manufactures nano powders which are different kinds of metals used as coatings for other nano-sized electronics or applications.
Nano Mix is another company that promotes the use of nanotube mixtures for the electronic industries.
