NANOTECHNOLOGY
Nanotechnology is the art of science to manipulating matter at
nanoscale.
A Nanometre is a unit length in the metric system, equal to one billionth
of a meter i.e. 10-9 .
Nanotechnology is manipulation of matter on an atomic, molecular,
and supramolecular scale.
It is the manipulation of matter with at least one dimension sized from 1
to 100 nanometers.
Nanotechnology refers to the constructing and engineering of the
functional system at atomic level.

ABSTRACT
The automatic transmission in automobiles is a unit which supplies the power from the
clutch to the differential. There are some types of gear transmission system. These
transmission systems help to improve the economy and efficiency of the work transfer.
Some machines with limited speed ranges, such as few forklifts and lawn mowers only
use torque convertor. Besides the traditional automatic transmission, there are also
other types such as continuously variable transmission, dual clutch transmission and
automated manual transmission system. Gear shifting strategy is the core of intelligent
control of any automatic transmission used in modern vehicles. It directly influences
the vehicle performance; drivers feel and fuel economy separately. The comparison
between automated manual transmission and automatic transmission system is
essential. The strategy of the gear shifting in manual transmission system is specified.

HISTORY
The first ever concept was
presented in 1959 by the famous
professor of physics Dr. Richard
Feynman.
Invention of the scanning
tunneling microscope in 1981 and
the discovery of fullerene(C60) in
1985 leads to the emergence of
nanotechnology.

Additive Manufacturing at the nanoscale?
Additive Manufacturing at the nanoscale is not a thing of the future
anymore. There are different techniques to achieve it: .
By building layer by layer with
layers that are one atom thick,
using focused-electron-beam
induced deposition (FEBID).
Two Photon Polymerization,
which is a technique similar to
Selective Laser Sintering (SLS),
based on the interaction of
femtosecond laser radiation
which induces a highly localised
chemical reaction leading to
polymerization of the
photosensitive material with
current resolution down to 100
nm. These three techniques
allow the 3D printing of nano-
objects.

Two-photon polymerization as a
direct laser writing technique allows for
creating complex three-dimensional
structures down to feature sizes on the
order of 100 nm. Key elements of two-
photon polymerization are lasers
providing femtosecond pulses, suitable
photosensitive materials (photoresists),
a precise positioning stage and a
computer to control the procedure.

A 3-D printing technology that uses two-photon lithography to rapidly
create detailed objects on the nanoscale.
his technique is encased in the direct laser writing family. Many UV
photosensitive materials can similarly polymerize by the simultaneous
absorption of two near IR photons (TPP: two photon polymerization).
TPL typically requires a thin glass slide, a lens, and an immersion oil to
help the laser light focus to a fine point to carry out curing and printing
photo resistive materials. It can produce features smaller than the laser
light spot (less than 150 nm), a scale no other printing process can
match.
