What is Nanotechnology?
it is design, creation & use of materials with at least one dimension measured in units of 1 nanometer.
At least it is:
Other sciences can have uses, for example:
- Computer Sciences,
- more for sure,
When at least one dimension is within bounds of: <1 nm, 100 nm> it is between the distance typical for single atoms (1 nm = 10-9 m) & the size of distances found in a solid matter
(100 nm = 10-7 m).
The diameter of an atom ranges from about 0.1 nm to about 0.5 nm.
Within such bounds material can have qualities that differ significiantly from those of the single atoms & of the typical crystals.
Thanks to nanotechnology, materials with qualities not found before can be created.
There are many, for example:
- Nanoelectromechanics (there can be nanoengines that can differ from microengines & larger for efficiency; there are also works on electric, magnetic & optic properties on nanoscale).
- probably more,
(to be corrected & elaborated when i can).
