research on nanotechnology

the Nano technique

Nanotechnology is considered one of the technologies belonging to materials science, and these technologies are related to the following sciences: physics, chemical engineering, bioengineering, and mechanical engineering, and it is a landmark specialized in researching and producing materials in the very small atomic world.

Invention of nanotechnology

After the manufacture and development of microscopes in the year 1930 AD, many capabilities emerged that science was able to add to technology by manufacturing devices that were smaller, more powerful, and more efficient than larger sizes. Engineers were initially able to manufacture electronic parts and boards that deal with units of millimeters, which are expressed by A meter equals 10^3, but the need for more specialized and reliable boards and electronic parts increased, so what followed was the micro, which is expressed as 10^6, which was considered a qualitative leap in the world of the technology industry, so the world was able to produce smart phones, small computers, and units. Small-sized storage, but the greed for science did not stop at this point. Rather, he thought about going beyond that in several stages and began working on the smallest, most established and accurate technology, which is nanotechnology, which is expressed from a meter as 10^9.

Nano size

A human hair is 50 micrometers, or 50 * 10^6, meaning that one hair has a thickness of 50 thousand nanometers, and the smallest length that a person can see with the naked eye is 10 thousand nanometers, and one nanometer is the alignment of 10 hydrogen atoms next to each other. Some, and what distinguishes nanomaterials, is that they do not follow size in their conductivity of electricity or heat. When electricity is conducted in a nanoconductor, it does not follow Ohm’s famous law in the electrical resistance of objects, whose equation links current, voltage, and resistance. In nanoconductors, electrical conduction depends on electronic flow only. Like river flow, for example, and therefore the electron needs to go through a flow process inside the conductor, as if I were describing some balls behind each other on a path, and each of the balls begins to flow and exit from the other end one after the other; This happens due to the small thickness of the conductor, which does not allow the presence of more than one electron on top of each other, and thus the absence of a field that would generate Ohm's law and electrical resistance.

The importance of nanotechnology

Field of electronic devices

This technology is considered the most important technical development in the twentieth century, as it contributed to the manufacture and invention of silicon or transistor electronics and electronic laboratories, and so-called small chips appeared, which led to a technical revolution in all fields: such as communications, computers, and medicine. The invention of small chips after the year 1950 AD resulted in the simplest application. An aid to technology in the modern world is that it created color television, before which only very expensive black and white television was known, which made it easier for everyone to obtain a color television for himself and his family.

medicine field

In the world of medicine, nanotechnology has provided amazing and brilliant work in amazing additions to that world. Recently, scientists have manufactured very small, microscopic robots according to nanotechnology that can move in the blood vessels and inside the body, which will later allow for the treatment of blood clots by means of an entire fleet of robots. Which is injected into the diseased area or swallowed for immediate treatment of the patient through it.
