INTRODUCTION

• The prefix nano means ten to the minus ninth
  power,or one billionth
• Nanotechnology deals with design manufacture of
  small electronic circuits mechanical devices
  built at the molecular level of matter.
• Nanotechnologists manipulates single molecules
  and atoms
• The main goal is to control individual atoms and
  molecules to create computer chips
• Manufacturing plants can produce circuits smaller
  than one micron(1000 nanometers).

Molecular Nanotechnology

• Molecular nano technology get essentially atom in
  right place.
• Make almost any structure consistence with loss
  of physics that we can specify in molecular
  detail.
• Have manufacturing costs not greatly exceeding
  the cost of required raw materials and energy.

4
Advantages of nanotechnology

• Nanotechnology will reduce the cost and increase
  the capabilities of space ship and space flight.
• With the help of nano, RAM can store billion
  billion bytes in volume.
• A male can be changed into female and female can
  be changed into male.
• Nanotechnology makes solar power economical by
  reducing its cost.

5
Disadvantages of Nanotechnology

• Scientists fell hard to find or repair the
  product.
• As all good fruits turn bad, their may be
  misutilisation of the resources .

APPLICATIONS MOLECULAR DIFFERENTIAL
GEAR

• Differential gear links two shafts through casing
  constraining sum of rational angels of shafts to
  equal the rotational angles of casing.
• The clockwise rotation of top shaft drives the
  side-gears in turn driving the counter clockwise
  rotation of the bottom shaft.

7

• The molecular differential gear structure is
  chiefly built of hydrogen,carbon,silicon,phosphoro
  us, nitrogen,oxygensulphur.
• The larger size of second-row atoms help in
  reducing the number of atoms needed to construct
  the outer cylinder of casing.

8
Fine motion controller

• Its core consists of shafts linking two hexagonal
  endplates, sandwiching a stack of eight rings.
• Each ring would be rotated by a lever driven by a
  cam mechanism.
• Rotating a ring moves strut, moving a strut moves
  platform, position in x,y,z roll ,pitch and yaw.
• The structure can execute motions over several
  atomic diameters with 90-degrees rotations, and
  contains fewer than 2000 atoms.

Visual images in nanotechnology

• These images show a structure with few thousand
  atoms, where each atom is a sphere.
• Nano systems have excellent black and white
  structure.
• The captions for black and white images in
  nanosystems provide documentation for
  corresponding colour images.
• These nanostructure need tight dimensional to
  ensure manufacturability.

Conclusion

• All nanodevices based on electrical, optical
  mechanical, chemical and biological effects are
  almost cheaper, clear and more precise.
• The properties of all materials based on how
  their atoms are arranged.
• Nanotechnology makes products lighter ,stroger ,
  smarter and cheaper.
