    1 : NANOTECHNOLOGY NANOCIRCUTRY & NANOCOMPUTING PRESENTED BY S.SHARMILI PRIYADARSINI
    2 : WHAT IS NANOTECHNOLOGY? Nanotechnology deals with the study of Materials of size 10-9 m. The materials in nanometer scale posses novel properties such as high efficiency & capacity than the normal materials.
    3 : WHAT IS NANO CIRCUTRY? Nanocircuitry deals with minimization of circuit size to nano scale. It helps the scientists & engineers in reduction of the size of computers & other electronic devices. The age of nanocircuitary begins with the invention of nanotransistors & ultra capacitors.
    4 : MOORE’S LAW: moore’s law states that,”the speed of the computer will be doubled in every 18 to 24 months. This is made possible by increasing the number of transistors fitted into a circuit.
    5 : ULTRA-CAPACITORS CAPACITORS ARE ENERGY SAVING DEVICES. THEY CONSIST OF TWO TERMINALS EACH STORE POSITIVE OR NEGATIVE CHARGES. THE ULTRA CAPACITORS ARE MADE FROM CARBON NANO TUBES. THEY HAVE HIGH RELIABILITY,COMPACTNESS.
    6 : TRANSISTORS: Transistors are the devices that forms the integral parts of the circuit. Transistors converts the weak signals into stronger signals. To convert the transistors to nano scale we are in need of switch on to carbon base instead of silicon.
    7 : Fig: TRANSFORMATION OF TRANSISTORS FROM HUGE SIZE TO NANO-CIRCUITS
    8 : CARBON NANOTUBES CARBON NANO TUBES ARE THE BASIC BUILDING BLOCKS OF NANO CIRCUITS. THEY ARE COMPOSED OF C-40 ATOMS. THEY ARE PATENTED BY IBM.
    9 : LATEST NANOPRODUCTS I-POD NANO developed by apple in 2007. Processors developed by IBM &VIA technologies.
    10 : Fig : I-POD NANO
    11 : RISKS: The electronics scientists need to develop new circuits to cope with nano circuits working with carbon nanotubes . The transistors will be 100 times smaller than the thickness of human hair so it is difficult to identify the problems in it. The ultracapacitors produces high heat, till today there is no remedy given to cool it.
    12 : OTHER APPLICATIONS OF NANOCOMPUTING: DISPLAYS QUANTUM COMPUTERS
