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.

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.

Who created nanotechnology?

Ричард Филлипс Фейнман

What is nanotechnology used for today?

Nanotechnology is being used in developing countries to help treat disease and prevent health issues. In industry, applications may include construction materials, military goods, and nano-machining of nano-wires, nano-rods, few layers of graphene, etc.

Is nanotechnology safe for humans?

Health Risks Of Nanotechnology : How Nanoparticles Can Cause Lung Damage, And How The Damage Can Be Blocked. However, concerns are growing that it may have toxic effects, particularly damage to the lungs. Although nanoparticles have been linked to lung damage, it has not been clear how they cause it.

Is Nanotechnology good or bad?

Nanoparticles do hold out much environmental promise. The same reactivity that makes them harmful in the body also means they can break down dangerous chemicals in toxic waste – or anywhere, for that matter. And their use in electronics drastically reduces power demand, which could cut greenhouse gases.

What was the first nanotechnology?

The emergence of nanotechnology in the 1980s was caused by the convergence of experimental advances such as the invention of the scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985, with the elucidation and popularization of a conceptual framework for the goals of nanotechnology beginning with

Do we have nanotechnology?

These do not exist. In the real world, materials scientists, physicists, and biology researchers are working at the nanoscale to build everything from stretchy circuit boards and self-healing plastic to super condoms and cancer medicines.

Why is nanotechnology bad?

Nanoparticles are likely to be dangerous for three main reasons: Nanoparticles may damage the lungs. This is both because of their size (as they can get deep into the lungs) and also because they carry other chemicals including metals and hydrocarbons in with them.
