What Is Nanotechnology


What Is Nanotechnology

What Is Nanotechnology? Nanotechnology is the science, engineering, and technology done on the nanoscale, about 1 to 100 nanometers.

Nanoscience and nanotechnology are the study and claim of tiny things. They can be rummage-sale in all other fields of discipline, such as chemistry, biology, physics, supplies science and engineering.

How did it start

A discussion by physicist Richard Feynman at a meeting of the American Physical Society at the California Institute of Technology launched the theories and concepts that underpin nanoscience and nanotechnology (CalTech) on December 29, 1959, entitled “There is plenty of space at the bottom.” Happened The term nanotechnology was used. In his talk, Feynman described how scientists could manipulate and control individual atoms and molecules. Professor Norio Taniguchi invented the term nanotechnology a decade later when he discovered ultra-precision machining. However, modern nanotechnology did not begin until 1981, when the scanning tunnelling microscope, which could “see” individual atoms, was developed.

Basic concepts in nanoscience and nanotechnology

It’s hard to envisage how small nanotechnology is. One nanometer is one-billionth of a meter or 10-9 of a meter. Here are some examples:

One inch contains 25,400,000 nanometers.

The width of a sheet of paper is around 100,000 nanometers.

On a scale of one nanometer to one metre, the volume of the Earth would equal one metre.

The capacity to see and control individual atoms and molecules is part of nanoscience, too, nanotechnology. The food we eat, the attires we wear, the structures and homes we live in, and our bodies are all made up of atoms.

But it is impossible to see a small thing like an atom with the naked eye. Likewise, it is impossible to see through the microscopes commonly used in high school science classes. The microscopes needed to look at things on the nanoscale were invented in the early 1980s.

The age of nanotechnology began when scientists obtained the necessary equipment, such as the scanning tunnelling light microscope (STM) and the atomic force microscope (AFM).

What Is Nanotechnology

Nanoscale materials have been utilised for millennia, although current nanoscience and nanotechnology are relatively new. For example, alternatively sized gold and silver particles added colour to the stained glass windows of medieval churches hundreds of years ago. However, little did the artists of the day know that the process they used to make these beautiful works of art led to changes in the structure of the material they were working with.

Scientists and engineers

Today’s scientists and engineers are deliberately looking for different ways to create materials on nanoscale so that their superior properties, such as higher power, lighter weight, increased control of the light spectrum, and their larger counterparts Compared to the more chemical reaction.
