NANO TECHNOLOGY Paper Presentation And PPT

Nanotechnology is a hybrid science combining engineering, chemistry and to a certain extent biology.  Computers will compute faster, medicine will cure more diseases, materials will become stronger, this technology that works at nanometer scale of molecules and atoms will be a larger part of our future, enabling great improvement in all fields of human presence. The concept of nanotechnology originated with American physicist Richard P. Feynman. In a talk to the American Physical Society in December 1959, Nanotechnology, the creation and use of materials or devices at extremely small scales. These materials or devices fall in the range of 1 to 100 nanometers (nm). One nm is equal to one billionth of a meter (.000000001 m), which is about 50,000 times smaller than the diameter   of a human hair. Scientists refer to the dimensional range of 1 to 100 nm as the nanoscale, and materials at this scale are called nanocrystals or nanomaterials.The nanoscale is unique because nothing solid can be made any smaller. It is also unique because many of the mechanisms of the biological and physical world operate on length scales from 0.1 to 100 nm.
