INTRODUCTION – THINKING THE NANO-WAY

The word nanotechnology is derived from the Greek word ‘nanos’ meaning ‘dwarf’. Nanotechnology involves working with matter at the scale of one-billionth of a metre (1mm). It refers to the manipulation of matter on the minutest scale i.e. atoms and molecules.
Every element is composed of matter. Matter is again the composition of infinite atoms. The atoms cluster together to form molecules, which, in turn, combine with several other molecules to form a basic molecular structure.


Regions of Cooling

The cooling of computer chips is incorporated through two regions respectively,
• Ion – Generating region
• Ion – pumping region


ION – Generating Region


This region consists of electrodes for electron emission and ion creation. Using electrodes placed close to one another on a computer chip, the new technique works by generating ions – or electrically charged atoms.


ION – PUMPING REGION

Pumping region made up of another set of electrodes needed to create the cooling effect. Clouds of ions are created when electrons react with air can then be attracted by the second region of electrodes and pumped forward by changing the voltages in those electrodes.


BIEFELD – BROWN EFFECT
The Biefeld – Brown effect is an electro kinetic effect that was discovered by Thomas Townsend Brown and Dr. Paul Alfred Biefeld. The effect is more widely referred to as Electro – hydrodynamics (EHD) or sometimes electro – fluid – dynamics.
