Nanotechnology?

Question

Can everyone please give me any infomation about nanotechnology and any examples of nanotechnology. No restrcition for any kind of infomation given. thank you

Answer 1

A field of science whose goal is to control individual atoms and molecules to create computer chips and other devices that are thousands of times smaller than current technologies permit. Current manufacturing processes use lithography to imprint circuits on semiconductor materials. While lithography has improved dramatically over the last two decades -- to the point where some manufacturing plants can produce circuits smaller than one micron (1,000 nanometers) -- it still deals with aggregates of millions of atoms. It is widely believed that lithography is quickly approaching its physical limits. To continue reducing the size of semiconductors, new technologies that juggle individual atoms will be necessary. This is the realm of nanotechnology.

Although research in this field dates back to Richard P. Feynman's classic talk in 1959, the term nanotechnology was first coined by K. Eric Drexler in 1986 in the book Engines of Creation.

In the popular press, the term nanotechnology is sometimes used to refer to any sub-micron process, including lithography. Because of this, many scientists are beginning to use the term molecular nanotechnology when talking about true nanotechnology at the molecular level.

Answer 2

Basically, nanotechnology just deals with the properties of particals that are smaller than micrometers. They have to use nanometers to measure how long they are, hence the name. Examples of nanomaterials would be carbon nanotubes, used as reinforcement to make things stronger, usually. Read encyclopedias or a Nanotechnology For Dummies book, they help. It's a very interesting field.

That should be enough to get you started. My yahoo e-mail is actually [e-mail] :) If you want a career in nanotechnology, you'll need to earn a degree in either mechanical, electrical, or computer engineering (probably mechanical).

In general, nanotechnology refers to technology that operates within lengths of a nanometer (1 billionth of a meter or less). The atomic level.

Answer 4

The study of how atoms behave at quantum levels.
