Applications through Nanotechnology
Abstract:
Nanotechnology is the branch of technology in which manipulation of nano (tiny) materials at atomic or molecular scale is done due to which its properties differ significantly from those at a larger scale. In the past the phenomena was already put to use in the field of cosmetics and sunscreen. But now the new technology will be utilised enormously in the fields of healthcare, filtration, infrastructure, electronics, power etc.
The first time the idea of nanotechnology(NT) was introduced in 1959, when Richard Feynman, a physicist at Caltech, gave a talk titled "There is plenty of room at the bottom" and then Drexler's vision of molecular manufacturing has evolved the field in the 21st century to largely include research in chemistry, materials science and molecular engineering.
Prof CNR Rao pioneered and fostered nanoscience research in India. Our former President APJ Abdul Kalam at his inaugural speech for Indo-US NT conclave on February 22, 2006 praised the Indian scientists for their NT work.
