Nanotechnology has been successful in almost all the fields irrespective of its kind and with the help of this technology it is possible to perform any type of operations starting from manipulating the molecules for separating impurities to the stage where it is the easy method for the production of power.In molecular manufacturing systems, using nanotechnology it is possible transform raw materials, in molecular form, into finished products. Impurities could be separated from feedstock molecules using a sorting rotor .
The purified molecules can be transported away from the sorter system using the molecular equivalent of a conveyor belt. Once a conveyor belt, the molecules can be transported to other belts, changing speed or frequency if necessary. The estimated belt speed is 0.5cm/s and the transition time form belt to belt is less than 0.2µs. a system for transforming a stream of small feedstock molecules into a stream of reagent moieties would be between one million and three million atoms in size. It could deliver the equivalent of its own mass is about 3 sec. The error is rated to be less than 1in 1015 operations at 106 operations per second. This gives a mean time to failure of about 3000 years. Other possible scheme has reagent moieties transported up through the centre of a hollow manipulator arm to a working tip for positional synthesis.
Nano technology is also playing an important role for electronic displays so as replace existing CRO and CRT’s and it is even competing with LCD (Liquid Crystal Display) which is the advanced trend in electronic displays.
The process involved for electronic display using nanotubes is as follows:
• Firstly, Mixture of C60 and nickel is ‘steered’ to specific surface sites by evaporating through a mask. The mask has an array of holes of 300 nm and can be moved with a precision of 1 nm.
• The C60/nickel mixture is evaporated sequentially in ultra high vacuum so as to form alternating layers of C60 and nickel with no impurities
• Then heat it up in the presence of a magnetic field. In this step, the C60 molecules are transformed into bundles of perfectly aligned nanotubes.
