Nanotechnology and carbon nanotubes

Renowned science fiction series "Star treka Replicator named in a reference device which is the object of the present kind of build that - it's a cup of tea as smolder or whether any weapons. Although it seems that it is not possible to make such a device, some people today are beginning to believe that it is not impossible to make such a device. Thanks to  a technology called ' nanotechnology ' , people today are dreaming of making fiction areality. Over the past few years, research and discovery on this technology has caused a stir among researchers at various levels. This agitation is also affecting the common people today.

What is nanotechnology ?
: If you want to know about it, you have to know the meaning of the word 'nano' first. The 'nano' is a tiny unit of measure. In 1986, Dr. K. Eric Drexler was the first to use the term 'nanotechnology'.

1 part of 100,000,000,000 (one hundred
billion) of 1 meter is called 1 nanometer, which is smaller than the wavelength of visible light. Note that the diameter of human hair is 50,000 nanometers. This gives a rough idea of ​​how tiny the nanometer is! In general, nanotechnology is the technology used to measure small objects that need to be measured in nanometers, although nanotechnology is not so easily defined.
Although there is disagreement among scientists as to how many nanometer objects belong to this technology, measurements ranging from 1 to 100 nanometers are usually considered in this technology.

Now the question is - 'Nanotechnology' belongs to which department of science. The funny thing is that it can't be categorized. Biologists, physicists, chemists, technologists - all are related to this technology. No one has a single dominion in this world. But it is very difficult for a person to gain in-depth knowledge about various subjects. However, the Nobel Prize-winning
scientist Dr. Horst Störmer expressed optimism that a common language would emerge among the subjects involved in nanotechnology, which would allow an experienced researcher in any field of science to continue research on the technology without acquiring in-depth knowledge of all subjects.

The problem with researching this technology is that the usual formulas for mechanics do not apply to this technology. Let's give a simple example - a straw or glass tube is dipped in a glass of water. Then it can be seen that the height of the water inside the tube and the height of the water outside the tube is almost equal - which is a normal phenomenon. But now if a tube smaller than before sinks, it can be seen that the height of the water inside the tube has increased more than the height of the water outside. The narrower the tube, the higher the water level.

This means that the smaller the diameter of the tube, the more the normality is disturbed. The failure of mechanistic formulas in the case of measurable objects on the nanoscale is more pronounced later. New mechanics is needed because classical mechanics cannot explain the properties of nanoparticles. Fortunately, decades before the beginning of research on nanotechnology, a new mechanism began to explain the properties of nanoscale objects. The name of this great mechanics is quantum mechanics.

We can't go to the other side of the wall without climbing a wall. But in the world of nanoscale, it is seen that an electron is easily able to cross the barrier without gaining sufficient amount of energy. Only quantum mechanics can explain this impossible phenomenon. In quantum mechanics this phenomenon is called tunneling. Numerous such phenomena are observed in the world of nanoscale. This means
that in order to know about nanotechnology, one has to completely forget the old knowledge and start anew.

So far today. Stay well, stay healthy, Allah Hafez.
