What is nanotechnology Wikipedia?

Nanotechnology (or ” nanotech “) is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. It is therefore common to see the plural form “nanotechnologies” as well as “nanoscale technologies” to refer to the broad range of research and applications whose common trait is size.

Who invented nanotechnology?

Ричард Филлипс Фейнман

What is nanotechnology in computer?

Nanotechnology , in the context of computer science, is a type of engineering geared toward building electronic components and devices measured in nanometers, which are extremely tiny in size and structure. It incorporates concepts from physics, biology, engineering and many other disciplines.

What is nano technology PDF?

Nanotechnology is the study of extremely small structures, having size of 0.1 to 100 nm. Nano medicine is a relatively new field of science and technology . An application of Nanotechnology in various fields such as health and medicine, electronics, energy and environment, is discussed in detail.

Why do we need nanotechnology?

Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.
