Nanotechnology

Nanotechnology is an emerging interdisciplinary technology that is booming in many areas over the recent decade, including materials science, mechanics, electronics, optics, medicine, pockets, energy, electronics, and aerospace. Its profound societal impact have been considered as the huge momentum to usher in a second industrial revolution.

The "nano" in nanotechnolgy emanates from the Greek word "nanos" actually dwarf. Scientists use this prefix to indicate 10'*' or one-billionth. One nanometer is one-billionth meter that's about 100, 000 times smaller than the diameter of a single human hair. Nanotechnology endeavors are aimed at manipulating atoms, molecules and nanosize particles in a precise and controlled manner to be able to build materials with a basically new organization and novel components.

The embryo of nanotechnology is actually "atomic assembly", which was initial publicly articulated in 1959 through physicist Richard Feynman. Nanotechnology is named a "bottom up" technology with which bulk materials can be built precisely in tiny play blocks, different from the traditional manufacture — "top down" technology. Therefore, resultant materials have fewer defects and higher quality.

The fundamentals of nanotechnology lie in the fact that properties of substances dramatically modify when their size is reduced towards the nanometer range. When a bulk material is actually divided into small size particles with more than one dimension
