Nanotechnology

Nanotechnology is the science concerned with building and manufacturing materials and devices at the nanoscale; It is a very small unit of measurement equal to one billionth of a meter; That is, ten times the hydrogen atom. The diameter of a human hair is about 80,000 nanometers. At this scale, the chemical and physical properties of materials differ; Such as color, hardness, conductivity, and reactivity is significantly different from the normal scale, for example, carbon nanotubes are 100 times stronger than steel, which consists mainly of iron and carbon, but six times lighter.[1] The first to address the idea and concept of nano It is the physicist Richard Feynman, during his famous lecture at the meeting of the American Physical Society at the California Institute of Technology in 1959 AD, by saying: “There is a lot of space at the bottom,” and he suggested that it is possible to control and control atoms and molecules, and after a decade Professor Norio came Taniguchi (Norio Taniguchi), who coined the term nanotechnology in his research on ultra-precision processing, and its applications began in 1981 AD with the development of the scanning tunneling microscope that can see each atom separately.
