KNOWLEDGE SHARING SESSION
11.07.2008
Presented by R.Venugopal
SYNOPSIS: History Definition Working Examples and its Products Applications
HISTORY: This term is first defined by Prof.Norio
Taniguchi in the year 1974.
Redefined by Dr. K. Eric Drexler, in his book Engines of Creation: The Coming Era of Nanotechnolog
(1986) and Nano systems: Molecular Machinery, Manufacturing, and Computation.
DEFINITION: Nano -One Billionth of a meter. It means the control of Matters (Atoms &
Molecules). It is a Multi-Disciplinary field.
WORKING: Top-Down Approach These seek to create smaller devices by using larger ones to direct their assembly.
Bottom-Up Approach These seek to arrange smaller components into more complex assemblies. In particular, to cause singlemolecule components to automatically arrange themselves into some useful conformation.
NANOTECHNOLOGY WORKING:
NANOTECHNOLOGY IN MANUFACTURING: Surface Textures of components. Manufacturing of Polymers. Design of Computer chip Layouts. Coatings over the Materials.
Application in Precision diamond manufacturing components
