What is nanotechnology And nano Tech? Nanotechnology Definition
Nanotechnology (nanotechnology or abstract nanotech) is the study of changing and controlling molecules at the molecular level. Generally, nanotechnology works with structures that are at least one dimension smaller than 5 nanometers. Nanotechnology is multidimensional, its boundaries range from conventional semiconductor physics to sophisticated molecular self-synthesis technology; From the control of molecular structures to the invention of new-featured nanoparticles.
The use of nanotechnology can bring about radical changes in many fields including medicine, electronics, energy production. On the other hand, it is also suspected of its potential adverse effects on the environment. Nevertheless, there is a great deal of research on nanotechnology in many countries of the world.
Why is everyone so interested in nanotechnology?
An easy answer to this is that the next day will be the age of nanotechnology. Did you have heart disease A nanorobot will enter your body and repair it? The clock in your hand will become your computer, your mobile, everything. It will be possible to change nanotechnology.
Nano Tech Overview
Nanotechnology “nanotech” is an operation of the nuclear, molecular, plus supramolecular balance. The earliest description of nanotechnology also mentions the specific technical goal of properly transferring atoms and molecules to make products in macroscale, now known as molecular nanotechnology. Nanotechnology is more commonly established by the National Nanotechnology Initiative, which interprets nanotechnology as a mono path with at least one dimension in the size of 1 to 100 nanometers.
This definition reflects the fact that quantum mechanical effects are important on this quantum-realm scale, and this definition varies from a specific technical goal to a research section involving all sorts of research and technologies that correlates with particular trait properties of a given size. Bottom it below the threshold How is it common to see research and applications whose common features are shaping plural “nanotechnologies” as well as “nanoscale technology”. Due to the potential variety of applications (including industrial and military), the government has invested billions of dollars in nanotechnology research. By 2012 the USA has invested the US $ 3.7 billion through the National Nanotechnology Initiative, the European Union has invested the US $ 1.2 billion and Japan has invested the US $ 750 million
Nanotechnology, as determined by size, is inherently widespread, with research and applications related to the fields of science, such as science, biochemistry, molecular biology, semiconductor physics, energy storage, microfabrication, molecular engineering, etc. Extension of a completely new method to the physical properties of conventional devices based on molecular self-assembly, from the development of new materials with nanoscale dimensions to direct control in the case of nuclear splashing.
Scientists are currently discussing the future implications of nanotechnology. Nanotechnology can be capable of producing many new materials and devices with a large number of applications such as nanomedicine, nanoelectronics, the energy production of biological components and consumer products. Nanotechnology, on the other hand, raises several of the same issues as new technologies, including concerns about the toxicity and environmental impacts of nanomaterials and their potential impact on the global economy and the situation of different generations. These concerns have sparked a debate among parties and governments over whether nanotechnology is linked to special regulations.
The generic name for advanced technology with nanometer precision (Nm, one billion in one meter). 1 nm is similar to the number of atoms, which means that the measurement and processing of the measured surface such as semiconductors, processing, and material manipulation is performed with precision so that atoms/molecules have to be homogeneous. Measurement and processing operation of the material surface atomistic level using the Sphinx Tunneling Microscope (STM) and Atomic Force Microscope (AFM), using various technologies such as the atomic layer epidemic, laser, and different ionization. Surface processing, Synchrotron B. as a minor source X-ray lithography, and the like have been attempted using ray (SOR).
History of nanotechnology
November 7th is likely to 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 the IBM logo with three Xenon molecules. On that day, it is possible for humans to create something of the choice by aligning the first molecule. So the day may well be the first milestone in nanotechnology for many years from today.
It was on this day that the first humans were able to break down the structure of the most important molecule of nature. There are many things that can be done by making the structure of a molecule as desired. The door to a huge potential was opened to the public. Let me explain a little. Coal is so cheap and diamond is so expensive because of the structural differences of the molecules. The main ingredient of the two things is carbon. Due to the differences in the composition of the molecules, diamond is the most solid product of the earth and the coal or pencil grain is soft.
But for the sake of nanotechnology, if we can sort this molecule at will, think about it. We can create whatever we want. In addition, Wilson Ho and his student Hyojune Lee from Cornell University demonstrated the process of pairing the molecule. Until now, the connection between atoms and atoms was organized only through chemical sales. But with nanotechnology, the possibility of doing much more than breaking or pairing atoms with molecules opened the door.
What is nanotechnology?
Nano is a measuring unit. The matriculation unit started in France in that year. The French National Assembly formed a committee to generalize the units, and they proposed the first decimal or matric method of ten units. And introduces a unit of length one meter. They call one meter of the earth’s circumference 1,5,3. The word meter is derived from the Greek word metron, which means, measure. In addition, one-third of a meter is called a centimeter. The law was enacted in France in that year. The definition of this meter was changed in that year.
The meter is called a fraction of the wavelength of radiation of the orange radius of Krypton 1. The definition of the meter was changed again in that day, according to the current definition, a meter of 202,2,7 percent of the speed of light in the air is called a meter. One-third of these meters 1,3,7,700 million is called a nanometer. The word Nanos is derived from the Greek Nanos word which means dwarf but it is used as a unit of size. And nanotechnology is the only technology that is involved in this nanometer scale.
The meter unit is intertwined with our daily life. All of the home furniture we measure is one of these meters. Until World War II, precision was measured on millimeter scales. There was no need to worry about anything smaller than a millimeter. But after the end of World War II, a new era in science and technology began. The semiconductor began its journey. And the beginning of this is with the discovery of transistors. Then our thoughts started with a micrometer unit. It is said that the journey began, microtechnology.
After this, the technology began to move at a tremendous pace. Various things, including television, radio, fridge, etc. And the battle started with how to make it smaller. The competition began with how small a company could get all these consumer goods. And all this is possible because of the semiconductor technology. When we first saw the size of the radio or the TV, we would laugh now. How did people use such big things? That question may come up. But now a thin TV like a calendar has come to hang on the market wall. Maybe the front will come smaller.
In that year, researchers at IBM first discovered that STM (Scanning Tunneling Microscope) can be observed with this device until molecules are formed. The invention of this machine has enabled nanotechnology to become a reality. How this STM works This device has a very fine pin-like tip, and when it is taken too close to a conductive object, it sends a small amount of electricity called tunneling. And it is through this amount of electricity that an image of the outer layer of the object is made. But what I would like to see in the case of this STM must be electrically conductive. But how can the structure of the electromagnetic molecule be seen? No man was sitting. The AFM was made possible by the way humans have come so far, impossible. In the case of STM, tunneling is done with electricity, and with AFM, it is possible to see the structure of a molecule with a fine pin.
Nanotechnology is the technique of changing and controlling substances at the molecular and atomic levels. One-quarter of a meter is called 3 nanometers. This technology is known to work in small quantities inside the substance.
Scientists say that with the use of nanotechnology, it is possible to bring about revolutionary changes in various disciplines of science, technology, including medical, electronics. On the other hand, extensive research is being done on its potential adverse effects on the environment.
