nanotechnology
Nanotechnology or just "nanotechnology" is that the engineering of matter at the atomic, molecular, and supramolecular scales. accolade winner nuclear physicist is attributable with popularizing the conception of engineering.
Description: Supramolecular weight
In his lecture, there is lots of area at all-time low, nuclear physicist delineated the practicability of synthesis through direct manipulation of atoms. moreover, nuclear physicist wrote that −
“I need to create a billion very little factories, models of every alternative, that area unit made at constant time. . . The principles of physics, as way as I will see, don't speak against the likelihood of manipulating things atom by atom. it's not an endeavor to interrupt any laws; it's essentially one thing that may be done; however it's not been worn out observe as a result of we have a tendency to area unit too massive.�
However, in 1974, Norio Taniguchi 1st used the term "nanotechnology". One micromillimeter, i.e. nm, is up to one billionth or 10-9 meters. Likewise, if we have a tendency to compare, then this is often a typical carbon-carbon bond length, or the space between these atoms during a molecule, that is within the vary of zero.12 x 0.15 nm.
Application of engineering in numerous fields
Let us currently discuss the appliance of engineering in numerous fields.
Nanotechnology is employed within the following areas of science −
Surface science
