3. Nano Technology
• What is Nano technology ? Nanotechnology ("nanotech") is
manipulation of matter on an atomic, molecular, and supramolecular
scale. The earliest, widespread description of nanotechnology ( 2).
However, unlike these other materials, they are not distinguished on
the basis of their chemistry, but rather, size; the nano-prefix denotes
that the dimensions of these structural entities are on the order of a
nanometer (10-°m)-as a rule, less than 100 nanometers (10-7)
(equivalent to approximately 500 atom diameters) (1). This ability to
carefully arrange atoms provides opportunities to develop
mechanical, electrical, magnetic, and other properties ( 1).

4. Intruduction
• Materials that are utilized in high-technology (or high-tech)
applications are sometimes termed advanced materials. By high
technology we mean a device or product that operates or functions
using relatively intricate and complicated principles. These advanced
materials are typically traditional materials whose properties have
been enhanced, and also newly developed, high-performance
materials. Classification of modern material ( Advances material ): 1.

5. 3. Carbon Nanotube ( What Is Carbon
Nanotube ? ).
• What is Carbon Nanotube ? The discovery of carbon nanotubes
(CNTS) in 1991, lijima ( japan ) opened up a new area in materials
science. A carbon nanotube is a tube-shaped material, made of
carbon, having a diameter measuring on the nanometer scale, with
length-to-diameter ratio of up to 132,000,000:1. A nanometer is one-
billionth of a meter, or about 10,000 times smaller than a human hair.
Carbon nanotubes have many structures, differing in length,
thickness, and number of layers.

14. 10.Conclution
• Nano science is the most rapidly developing field that has been
fascinating scientists for years and the last decade has been the most
productive in terms of research on it. But for this to be productive in
every aspect its impacts both positive and negative are to be studied
extensively and thereupon reach a point where negative aspects can
be worked around. It is however a field having quite a potential for
future applications. Nanomaterials, particularly carbon nanotubes
(CNTS), hold great promise for a variety of industrial, consumer, and
biomedical applications, due to their outstanding and novel
properties. 23 of 25
