What is Nanotechnology?

History of Nanotechnology:

On January 29, 1959, Richard Feynman gave a lecture at the American Physical Society in a conference titled “There’s Plenty of Room at the Bottom” in the California Institute of Technology. This speech was the first to give the idea of nanotechnology. November 9, 1989, will be considered one of the most memorable days for Nanotechnology. On this day, Don Eigler and Erhard Schweizer at IBM’s Almaden Research Center in California created IBM’s logos with 35 Xenon molecules. On the same day, the first molecules were made possible to create something in the right way. On this day, the first man was able to break the structure of the most important foundation of a molecule. It is possible to do many things by creating molecules in a way that is desired. Huge possibilities were exposed to the people of the door. Coal is so cheap and diamond is so expensive due to the structural difference of molecule only. The main components of the two things are carbon. Due to differences in the formation of the molecule only, diamond is the hardest material in the world, and the peel of the pencil is soft.

In 1999, Cornell University demonstrated the process of pairing Wilson Ho and his student Hyojune Lee molecules. Until now, connections of molecules were organized only through a chemical reaction. But by breaking nanotechnology, breaking the molecule atom could open up the possibility of doing many things.


What is nanotechnology?

Nano is a measurement unit. The matrix unit was started in 1790 in France. The French National Assembly constitutes the Committee for Generalizing the Units, and they offer the first decimal or matriculation method of ten units. And the length of the unit started one meter. They say one meter in one part of the Earth’s 40,000,000-odd diameter. The word meter comes from the Greek word metron, which means measurement. Another part of the meter is called centimeter. In 1793 it was introduced in France by law. In 1960 the definition of this meter was changed. One part of 1,650,763.73 percent of the wavelength of the radiation of the orange radiation of Cryptan 86 is called a meter. In 1983, the definition of the meter was changed, according to the current definition, a fraction of 29,99,792,458 percent of light speed in air is called meter. One part of this meters 1,000,000,000 (100 million) share is called a nanometer. The word nano comes from the Greek Nanos, which means dwarf but it is used as a measurement unit. Nanotechnology is the only technology that is related to this nanometer scale.

The meter unit belongs to our daily life. All of the house furniture we measure is the meter unit. Until the second world war, the composition of the millimeter was measured on the precision of the machine. Millimeter did not have any idea about anything small. But after the end of World War II, a new era of science and technology began. The semiconductor started its journey. And this is the beginning of the transistor invention. Then our thoughts started with the micrometer unit. It can be said that the journey started, microtechnology.

After that, the technology started moving at a very fast speed. Various accessories, including television, radio, refrigerators etc. And the war started with how it can be reduced. Any company can reach out to all these small consumer goods, its competition started. And all this is possible, for the benefit of semiconductor technology. If we see the size of the first radio or TV, we will get a smile now. How did people use such a big thing? Maybe that question might come. But now there is a thin TV like the calendar for hanging on the market. Maybe the front may be smaller.

In the year 1980 IBM researchers first discovered that STM (Scanning Tunneling Microscope) was able to see this device as molecule until it was formed. The discovery of this device has enabled nanotechnology to become a reality. How does this STM work? This device has a very fine pin-like tip and when it is taken very close to a conductive object, then very little electricity is transported in tunneling. And with this amount of electricity, the image of the outer layer molecules is made. However, in this STM case, it will be necessary to conduct electricity. But it can be seen how the structure of the molecule insulator of electricity? No people did not sit. The way humans have come so far as possible through impossible, it is possible that this impossible could be made possible by the AFM. Tunneling work is done in the case of STM and it is possible to see the structure of molecules with a fine pinned AFM.

Nano Technology from Nano Science:

Do you remember the Google Map Satellite View? Where in the early days, our world seems to be a big round of blue-green. Because of the green trees and the ocean on most of the Earth’s surface, a blue-green appears to be bigger than the Earth’s surface. Now start zooming on the map, gradually many countries will be watching, after that, the country’s cities will be noticed and then there will be a particular city on the screen. Now start zooming on the city, an area will come and finally, the zoom will end in a mansion or a house. But is that the last end of the world, that is the smallest element in the world by which this planet was created? Of course not. Nanoscience is used to look at things smaller than our normal eyesight. Now let’s go back to the Google Map which ended on a mahalla. Now let’s go zoom, maybe a field of mahalla can be found on the mahalla and once zoomed, one can stop at a grass. The idea started with Nano Science and started to zoom the grass. If zoomed grass, plant cells can be seen in it and it can be seen how it is making food for themselves with sunlight. If you do more zoom in this way, you will see that the plant molecules are composed of carbon, hydrogen, and oxygen, and once things are all divided. So this is Nano Science, which helps us to understand the very roots that how each element is made and its core is what it is. And when we can understand Nano Science, we can use it to create something new and it will be called Nano Technology. Because technology comes from science and follows the rules of science, making our everyday life easier is the technology work. Now let’s take a few simple ideas about nanotechnology what’s actually this and how it works. I will not go into any complex discussions, try a simple and straightforward interpretation of all the facts with just a few examples. Well, think of a cloth and suppose we have reached the smallest point of the nanoscale of that cloth, then what can be seen. Yes, of course, we must reach atoms of atomic atoms. There may be a thread from one cotton thread to the other. Now suppose there is a substance that has the power to exclude any fluid. So, if we reach the nanoscale of that substance, we can know the structure of that substance and change the anatomic structure of the cloth with that substance, but what will happen? Then it will be possible to create a cloth which will discard any fluid with water. Suppose your white shirt filled the yellow juice of curry! What is not it boring? But after improving nanotechnology, your shirt will get rid of the buttermilk, meaning that if the shirt sticks in the curry, it will not cause any stains. Hope you’re clear about the main subject of Nanotechnology.


Use of Nano Technology:

Most of the advantages of Nanotechnology can be seen in the future, but in the future, this technology is helping to change the world in different ways. You might think Nano Technology is a great thing at once and it’s a whole new technology-because “technology” means we think of the human technique. But our life itself is a great example of nanotechnology. Our bodies work in proteins, viruses, bacteria, cells, etc. in the form of nanotechnology.


Nano Material:

Maybe you are currently using Already Nanotechnology. Maybe you wear nanotechnology pants or your shirt is made of nanotechnology. Even from your bed linen to the traveling bug, it is also ready for nanotechnology. Made of nanotechnology, the fibers of the fabric are so fine that dust particles can not stick to it, so the cloth is much less messy. Nanotechnology is used in some branded sunscreen creams, just because the cream is applied to your skin, it only puts the titanium oxide or zinc oxide layer, so that it blocks the sun’s harmful ultraviolet rays. Many paintings made in nanotechnology work in this way, so it is more lasting and less corrosion.


Carbon Nano Tubes is the most outstanding Nanomaterial. As a result of its Atomic formation, it turned it into a very strong substance. It is possible to make any taller measurements in fiber drawing. Besides, you can read this article to find out more about the most powerful materials.


Nano Chip:

Micro Electronics is another form of nanotechnology. Typically the word “micro” is used in microelectronics because its drawing is due to the microscopic scale. But computer scientists have said that if more transistors can be used in the same place, then the size of the computer is smaller and more powerful. That’s why today’s computers are much smaller, much stronger and cheaper in size. Presently, computer processors are prepared by 100-200 nanometers transistor and the day is being reduced by more size and all of this is possible due to Nanotechnology.

Not just computer processors, but flat screen HD TVs, smartphones, iPads, etc. all have chips installed using Nanotechnology.


Nano machine:

Another interesting aspect of Nanotechnology is that it is possible to create a very small machine; From gears, switches, pumps, machines – and completely different atoms. Nanomachines can be made nanorobots, which are called nanobots. Nanobot can be injected into our body so that it can fight with adverse conditions.
