Summary

The latest technology is based on development in the field of Nano electronics. This article is based on the information related to the field of nanotechnology. The nanotechnology is the best approach in engineering that may provide ultrafast, very stable, highly efficient and highly strong materials and devices. The development noticed in the field of nanotechnology is not revolutionary, it is evolutionary. The latest development of carbon nanotube in the field of nanotechnology takes its applications at a very high edge. CNT's are the carbon tubes that may be comprised in many forms depends on its construction pattern. These forms are generally known as chiralities. The most common and highly effective carbon nanotube forms are armchair, zigzag and chiral carbon nanotubes. These chiralities or forms of CNT differ in many aspects such as the diameter of tube and stiffness of the tube. This article also discusses the methods that are used in constructing materials or CNT proposed by different research mostly conducted by American Army.

The carbon nanotube's bonds are considered as the strongest bonds found in the graphite and other material bonding (Dresselhaus, 2004, P 65-98). Some professional claims CNT as the material that not only provides strong material but also provides a stiffed material which is not found in any other metal and materials in the world. This is due to the reason that when the material is strong then it is always hard, while in the case of CNT we can achieve both properties by using same material. This article also discusses the applications of the CNT in many fields such as its application in manufacturing a very strong concrete material. The concrete used today instead of considering as very strong material, it has many cracks that are considered as the concrete cracks. The usage of the CNT technology in manufacturing of the concrete can provide concrete that is the very strong when it is compared to conventional concrete material.

There are two graphs present in the article that defines the effectiveness of the CNT based materials on the basis of some basic properties of materials. The first graph defines the relationship between stress and strain of the four materials and defines that what amount of stress is acceptable for such materials and what value of strain is provided by the material. In the second graph the author of this article compared the stress and strain relationship of CNT ...
