The nanotube were one of the first real nano materials to be produced at the molecular level by engineering methods. Estimates vary as to exactly how much carbon nanotube it has. But experiments have already shown that the tensile strength of these materials is more than 40 times higher quality steel. According to some estimates, a strand of nanotubes thinner than a human hair can hold a trailer. Many nanotechnology experts point out that nanotube are not only the most powerful materials ever made, but are among the most powerful materials that can be made in the future. These nano structures are designed to benefit from unique properties.
What are the nanotubes and their uses?
Its unique properties include high Young’s modulus and good tensile strength on the one hand, and the carbon nature of the nanotubes (because carbon is a lightweight material, very stable and easy to perform processes that are cheaper to produce than metals). It has led to significant research in the past decade on the efficiency and effectiveness of nanotube growth methods. Much theoretical and practical work has focused on the atomic structure and the electronic structures of the nanotube. Extensive efforts have also been made to address the mechanical properties including Young’s modulus and tensile strength and defect mechanism and the effect of nanotube deformation on electrical properties. It can be said that the nanotubes have a special interest in their unique structure and properties. You can read more about nanotubes uses in many websites.
The nanotubes become conductive or semiconductor based on how their graphite plates roll. In other words, because the nanotubes at the molecular level look like a wired beam, interconnected by carbon atoms, they form hexagonal cylindrical walls that are only a few nanometers in size. The torsion angle of a type of nanotube, defined as the angle between its hexagonal pattern axis and the tube axis, determines the conductivity or non-conductivity. Other research has also shown that the radius change also allows for bond lengths to be insulated and metal nanotubes insulated. You can read about carbon nanotubes definition in many books.
When do nanotubes invented?
Years ago, Samoyajima was researching behind an electron microscope that observed nanometer strands in sooty black sediment. These strands were made of pure carbon and were symmetrical and arranged like regular crystals. These large, beautiful, and very tall molecules were soon named nanotubes and have been the subject of advanced scientific and engineering studies until now. “It is true that carbon nanotubes were amazing for me,” Ijima says, “but not all was a coincidence, because I had a lot of experience in observing small-scale carbon samples like amorphous carbon and very thin graphite layers; So for years I was familiar with carbon structures and worked on them. The discovery of Fuller by Richard Smalley and his colleagues encouraged me to think of new carbon structures. Ijima believes the cost of nanotube research is very high. However, the construction of nanotube superconductors has a higher priority.
How are nanotubes produce?
The nanotubes are significantly hard and strong, conducting electricity and heat. These properties have led to the use of these materials in the electronics industry.
Carbon nanotubes are large molecular wires in which electrons can move freely and their behavior is complex. In this regard, the behavior of multi-walled nanotubes is much more complex than single-walled because the side-layers affect each other. Modeling such effects is currently under investigation. The researchers hope to extend the dimensions of the wires or parts to about nanometers or less by replacing them with nanotubes. These components can work with electronic circuits much faster and with less power than current circuits.
Lamps made of carbon nanotubes are less expensive to manufacture. In addition, longer life and greater color stability than conventional bulbs are other benefits. You can read about carbon nanotubes properties in many websites.

The nanotubes are hollow carbon structures. Therefore, it is possible to put foreign materials inside them. For example, by incorporating metals into the nanotubes, the electrical properties of these materials can be improved. Research has shown that open nanotubes act like a hollow straw. These molecular canes can pull some elements through the capillary action and under certain conditions. Carbon nanotubes have also been investigated for storing alkanes and hydrogen fuels and creating fuel cells. It is possible to store hydrogen inside single-walled carbon nanotubes.
