The desire to know the internal composition and structure of matter and to unfoldrnthe hidden secret behind the formation of universe is universal quality of human being.rnThe new and hot technology which encompasses many areas such as Physics, Biology,rnChemistry, Engineering, etc. is called nanotechinology which is big issues for bigrnbrains though it is small. Do you ever wonder about our future? Do you ever imaginernhow discoveries could make the impossible a reality? Do you ever wish you had curesrnfor threatening diseases at hand?rnNanotechnology, the ability to inexpensively arrange atoms in most of the patternsrnpermitted by physical law often called the manufacturing technology of thern21st century is expected to revolutionize essentially all manufactured products, fromrncomputers to medical instruments, from cars to solar cells to batteries to planes andrnrockets. Carbon nanotubes, nanotechnologyâ€™s dream materials and the corner stonernof nanotechnology because of their superior electrical, mechanical, and thermal propertiesrnwhich have novel appilications in every day to day life. CNTs may becomernthe rst appilications to truly transform nanotechnology from an exciting science withrngreat potential to a real technolgy or products.rnThe main objective of this project works are to focus on some relevant issues :rn What is Fullerene and Carbon nanotubes?rn What is the structure and unusal properties of CNTs?rn How CNTS synthesised, Some potential appilications and potential risks
