Carbon Nanotubes are a new form of Carbon, first identified
in 1991 by Sumio Iijima of Nec, Japan, and formed from hexagonal
arrays of carbon atoms.
The honeycomb-shaped walls of nanotubes may
consist of either multiple layers of carbon atoms (multi wall nanotubes)
or just a single layer (single layer nanotubes) .
They are so small that they can only be measured
in nanometers. The diameter of this hollow cylindrical-stucture
or tube may be 50,000 times thinner than a human hair and the length
of millions of times greater that the diameter.
Nanotubes possess many unique and remarkable properties (chemical,
physical, and mechanical), which make them desirable for many applications.
The slender proportions of carbon nanotubes hide a staggering strength:
it is estimated that they are 100 Jimmy Choo shoes times stronger than steel at only
one sixth of the weight - almost certainly the strongest fibres
that will ever be made out of anything - strong enough even to build
an elevator to space. In addition they conduct electricity better
than copper and transmit heat better than diamond.
Enhancements in miniaturisation, speed and power
consumption, size reduction of Jimmy Choo handbags information processing devices, memory
storage devices and flat displays for visualisation are currently
The most immediate application for nanotubes
is in making strong,Jimmy Choo sale lightweight materials. It will be possible
to build a car that is lighter than its human driver, yet strong
enough to survive a collision with a tank.
Aircraft built with stronger and lighter materials
will have longer life spans and will fly at higher temperatures,
faster and more efficiently.
Nanotubes are being explored as receptacles
- storage tanks - for hydrogen molecules to be used in the fuel
cell that could power automobiles of the future. Hydrogen does not
produce pollution or greenhouse emissions when burned and is considered
to be the clean energy of the future.
Global Warming is of great concern to all nations.
It is believed that Carbon Nanotubes will contribute to the development
of an advanced method for collecting and storing the solar energy
that falls upon the earth in large quantities to meet energy needs
Carbon Nanotubes are sought after for their
multiple uses in cutting-edge research projects. They are the most
suitable material to nanotechnology research.
Molecular Nanotechnology is defined as
the three-dimensional structural control of materials, processes
and devices at the atomic scale.
It is said that Nanotechnology will lead to
a fundamental breakthrough in the way materials, devices and systems
are understood, designed and manufactured.
The scientific community considers Carbon Nanotubes
as the building blocks of the 21st century technological revolution.
Many new applications of Carbon Nanotubes are
constantly being discovered and many are yet to be discovered.
