Nanotechnology
In
this we will share information regarding the nano technology , its types ,
where it is used , about its particle nature and many more information
Everyone
one had heard about Nano cars. The specialty of the car was its size (small)
and the same is for nanotechnology means the things are very small .And this
nanotechnology is so effective that it can be used in future everywhere . Nan
science is used in chemistry , biology and many other engineering fields.
So for this you should have a knowledge of nanotechnology .
Nanotechnology is a catch- all phase of the material and devices that will be
operated by the scale called the Nanoscale .
What
is Nanotechnology ?
“Nano”
is a Greek word that means “small” .In nanotechnology the term “nano” is
a particle which is made from very small size things .
In
this way the Nanotechnology is a kind of technology or applied science
which work on particle which are smaller than 100 nanometer (nm).In
Nanotechnology the matter which are nuclear , atomic ,super molecular
scale is controlled and studied .
The idea
of “Nanotechnology” was given by physicist Richard feynman” . He was
giving a lecture in his meeting and when he had said the line “There is plenty
of room at the bottom “ .
on
the day 29th December 1950 “California institute of technology
“ and this began the topic for his research . and then after a
decade professor NORLO Tamilgun .
He
pronounced the word called “Nanotechnology” . and in 1981 when the
term “ELECTRON” was discovered and from that time the research has
started for Nanotechnology and from the time many efforts were made to do
a successful research on Nanotechnology.
Nanotechnology
is the study related to the nanoparticles and the operations which have been
controlled by both the physical as well as chemical properties .
What
nanotechnology can do ?
In today’s
world people are more focused on nanotechnology because of its small size. The
term “ Nanotechnology” or “ Nan science” is not a new term for all of us .
Because
long ago biochemists (nanotechnology in medicine) have
introduced these terms . Nanotechnology is used in computer chips for more than
20 years . Nanotechnology works on small particles . it holds great power .
current uses of nanotechnology
Because by
using this technology the efficiency and energy consumption can be effectively
increase , we can clean our environment , many of the diseases bacteria
can be cured .
The
specialty of Nanotechnology is that the product which we can made by using this
uses of nanotechnology
technology
can be of very small size ,
the
product weight can be very less (nano products we
use today )
the
cost of the nano products will be less as compare to other products
and
the raw material which will be used to make this product will be very less
,
and the energy requirement will be very less ,
By using
this nanotechnology BIO SCIENCE , MEDICAL SCIENCE , and in the
ELECTRONICS fields there will fast development in all these fields .
cancer nanotechnology
Did you
know that in the future there will be so small Nano robots we will get to see .
These small robots will be so small that they can’t be seen with our naked eye(nanotechnology in medical field) . They can be sent in our
body for the detection of the bacteria and some unwanted material
which can harm us and they can save us from not getting infected by
any diseases .(future of nanotechnology )
the future of nanotechnology in medicine
So can we
understand the word “NANO SIZE “ ?
So to
understand this it is important for you to know that 1 Nano
meter = 1 Billionth of size . 1 inch = 25,400,000 Nano meters .
The
newspaper sheet is approximately 1 lakh Nano
meters . By knowing all the above sizes we can
understand that how small this Nano particles are .
Benefits
of Nanotechnology
current uses of nanotechnology
With the
help of Nanotechnology we can make medicines which determines the
bacteria which are responsible for the cancer
nanotechnology in food
examples of nanotechnology products And by using this
Nanotechnology we can find any kind of molecular assembling and can be
understood easily . and its size can be made as small as our hairs .
how is nanotechnology used today
1.
It has very small size
2.
It has high surface to volume ratio (nanotechnology
products)
3. It Has higher hardness than other materials or particles
4. It has higher breaking strength
5. It will have toughness at low temperature .
6. It will behave like super plasticity at high temperatures .
7. It has high chemical selectivity at surface sites .
8. It has high surface energy .
Types of Nanotechnology ?
Four kinds of nanotechnology
1. Carbon Nanotube
2. Optical or particle wave based nanotechnology
3. Crystal sand nanotechnology
4. DNA Nanotechnology
NANO MATERIALS
The
material which will be at least of the dimension between 1 NM to 100 NM
will be called as nano materials .These are tiny particles of high potential .
These
particles can exist in many forms which are particles , powder ,
tubes etc .
They can
be metals , cosmic , or any composite material or any
polymeric materials .
NANO LAYER
The nano
material which will be of the dimension of 1nm and nearly equal to 100 NM will
be called the Nano layer .
Nanotube
The nano
material which will be of the two dimensions between NM to 100 NM will be
called Nanotube .
Nano particles
The nano
material which will be of three dimensions and will be in the range of 1 NM to
100 NM will be called as the nano particles .
Quantum Dots
The semiconductor
nano material between 1 NM to 100 NM will be called the quantum dots .
These will
have dimensions from 2 to 10 NM
These
quantum dots can produce many different colors which can be determined by the
size of the particle .
Career in nano technology
To make the career in Nanotechnology we should have a good knowledge of chemistry , physics , and all the fields related to the science .
