study
Science /ˈsaɪəns/
It is the knowledge
about the structure
and behaviour of the
natural and physical
world.
Technology /tekˈnɒlədʒi/
It is the practical
application of scientific
knowledge.
Nano /ˈnænəʊ/
It is a unit of
measurement for tiny
matter.
1 nano = 10−9
Let’s take a look into
Nanotechnology !
3. /ˌnænəʊtekˈnɒlədʒi/
Nanotechnology is the manipulation, control, and use of
nanoparticles. Nano-particles are impossible to see with
the naked eye because they are so small that one
nanometer is a billionth of a meter. The use of
nanotechnology helps to improve the quality of material,
medicine, etc. by modifying the nanoparticles.
4. Some Nano-terms.
Silver nanoparticles
have unique optical,
electrical, and thermal
properties . They
continuously release a low
level of silver ions to provide
protection against bacteria .
Nanogenerator is a
prototype nanometer-scale generator that produces
continuous direct-current electricity by harvesting
mechanical energy from such environmental sources as
ultrasonic waves, mechanical vibration or blood flow
Nanocomposites
are materials that
incorporate nanosized
particles into a matrix
of standard material.
Nanofibers are a
new class of material
with special
properties that make
them suitable for a
wide range of
applications.
Nanobots are
incredibly tiny robots,
down at a microscopic
scale.
