Graphene nanotubes made from

Nanotubes of carbon are made from graphene-like sheets roUed into a tube. Carbon nanotubes are considered to be the strongest and stifFest materials yet discovered in terms of tensile strength and elastic modulus, respectively. This strength results from the covalent sp bonds formed between the individual carbon atoms. 

Among nanofillers, carbon nanotubes (CNTs) have gained much attention because of their superior electrical, mechanical, and thermal properties. They are nanotubes, made by wrapped graphene layers, with a diameter of few nanometres, a length from a few microns up to millimetres, and a graphite-like structure. They can be single walled (SWCNT) or multi walled (MWCNT). In this paragraph, results refer to MWCNT, unless otherwise indicated. 

Another area of research is the construction of molecule-sized transistors made from graphene or carbon nanotubes and other materials. These technologies, when fully developed, will completely change the nature of computing by enabling the construction of a quantum computer, a device that could carry out in seconds calculations that existing computers would require possibly billions of years to complete.
