the Nano technique

  Nanotechnology is a technology of materials science. These techniques are related to the following sciences: physics, chemical engineering, bioengineering, and mechanical engineering, a teacher specialized in material research and production in the very small atomic world.

                                      The invention of nanotechnology

After the manufacture and development of microscopes in 1930, there were many capabilities that science was able to add to the technology by making the devices smaller, more powerful and efficient than the larger sizes, engineers were able to initially manufacture pieces and electronic boards dealing in units of meters and expressed in meters However, the need for more specialized and reliable electronic plates and pieces has increased. The next step is the micro, which is expressed in 10 ^ 6, which was considered a quantum leap in the world of the technology industry. The world was able to produce smart phones, small computers and storage units Small size , But did not stop the greed of science to this extent, but thought to go beyond that multiple stages began work on the technology is smaller and more established and accurate, which is the nanotechnology, which is expressed from the meter B10 / 9.

The size of nanostructures

 The human hair is 50 micrometers, 50 x 10 ^ 6, ie, one hair has a thickness of 50 thousand nm, and the smallest length can be seen by the naked eye is 10 thousand nm, and the nanometer is the alignment of 10 hydrogen atoms next to each other The nanomaterials are characterized by the fact that they do not follow the size of their electrical or heat conductivity. When the electricity is connected to a nanomagnetic conductor, it does not follow the famous ohm law of electrical resistance of objects that is linked to the current, voltage and resistance. Such as river flow So the electron needs to pass through a flow process inside the conductor as if I describe some balls behind each other in a way, and each one of the balls starts to flow out of the other end one by one; this occurs because of the small connector thickness that does not allow more than Electrons are superimposed on each other and thus there is no sphere that will generate Ohm's law and electrical resistance.

The importance of nanotechnology field of electronic devices

This technology is the most important technological development in the twentieth century, which contributed to the manufacture and invention of silicon electronics or transistor and electronic laboratories, and emerged so-called small segments that led to a technical revolution in all areas: communications, computer, medicine and invention of small slices after 1950 led as the simplest application And help for technology in the modern world that they created the color television, which was previously given only a high-priced black and white TV, which made it easy for everyone to have a color television for himself and his family.

medicine field

In the world of medicine, nanotechnology has provided amazing work and brilliance in amazing additions to the world. Scientists have recently created micro-micro-robots, which are able to move in the arteries and inside the body. This will allow blood clots to be treated by a fleet of robots Which is injected into the diseased area or ingested for immediate treatment by the patient.
