Nano is a unit of measurement. Matric Single......
It started in 1890 in France.
National Assembly of France
To generalize the units
The committee is formed and they are the first
Matric of decimal or ten units
Suggested the method. And length
Introduced one meter. They
Of the earth
One of the 40,000,000th part of the circumference
The meter said. The word meter is a Greek word
comes from metron which means,
Measurements. Also 100 percent of the meter
One part is called centimeter.
Introduce it by law in France
The definition of this meter in 1960
Is done. Krypton 6's orange
The wavelength of radiation
One part is called a meter.
Re-define the meter in the year
Is changed, current
By definition, light in the air
299,792,456 to one part
Is called. 1,000,000,000 of these meters
Crore) one of the divisions
The part is called nanometer.
The word nano is the Greek word nanos
Which has a lexical meaning
dwarft but it is a unit of size
Being used as. And this
All that on the nanometer scale
That's what technology is all about
The meter unit is our daily routine
Involved in life. Home
This meter of furniture we all measure
Single. Before World War II
Electronics in millimeter scale
Fineness was measured. Small of millimeters
A time to think about something
There was not. But World War II ended
Later, one new in science and technology
Of the era
The beginning is. The semiconductor is his journey
Did. And the beginning of it is the transistor
With discovery. Then the micrometer
Our thinking started with.
It can be said that the journey has begun,
Later technology started advancing
At speed. Various things, of which
In television, radio, fridge
Etc. etc. And
How to make it smaller
With that the fierce war began.
All of this is how small the company is
Things are ours
Can reach, his
The competition began. And all this
The thing is possible, semiconductors
Related to the welfare of technology. First
The size of the radio or TV
We will get a smile now. So much
Big things people used to do
That question may come up.
Now for hanging on the wall in the market
Like a calendar
The thin TV has arrived.
The front will probably come smaller.
In 1960, IBM researchers first
STM (Scanning Tunneling)
Visit the molecule structure with the instrument
The invention of this device
Who has been able to make it a reality.
How this STM works. On this device
Sharp pin-like pointed tip
There is and when it is no conductive
Of the object
Taken too close, then
There is very little called tunneling from that
The amount of electricity is transmitted. And this
The amount of electricity in the object
Image of outer layer molecules
Is made. However, this is STM
Whatever I want to see in the case
Must be electrically conductive. But electricity
Formation of non-conductive molecules
How to see? Not people
Didn't sit down. By making the impossible possible
The way it has come so far
The impossible was made possible by AFM.
In this case tunneling power
Is worked with and with AFM
It is possible to see the molecular structure with pins.
Richard January 29, 1959
Feynman California Institute
Held in off-technology
At a meeting of the Physical Society
Plenty of Room at the Bottom
Gave a speech. This is the first speech
Gives the idea of nanotechnology. 1969
Of the year
November 9 at Nanotechnology
One of the most memorable days for
Will be considered. This
Of IBM of California during the day
Don Eigler at the Research Center and
Schweizer IBM with 35 Xenon molecules
Created the logo. That day
Arrange the first molecule as desired
It is possible for people to create.
The first man is the most important of nature
Capable of breaking down molecular structures
Was. The structure of the molecule is arbitrary
A lot can be done by creating. One
Humans are the door to huge possibilities
The front is exposed. Only molecules
Due to structural differences
Coal is so cheap and diamonds are so expensive.
The main component of two things is carbon.
Just because of the difference in molecular structure
The hardest product in the world anymore
The tip of a coal or pencil is soft.
Cornell University in 1999
Ho and his student Hyojune Lee
Pairing of molecules
Demonstrates the process. So long
Molecules up to-
The connection of atoms is only chemical
It was organized through reactions. But
Molecules through nanotechnology-
By breaking or attaching atoms
It opened the door to the possibility of doing nothing.
Field of Nanotechnology
There are two processes. On a hall
Top to Bottom and the other
Bottom to top.
The method is to cut any thing short
He is given a specific shape.
The field is usually etching
The process is related. And downtown
With small things of small size
To make any thing. Ours
Current Electronics Hall, Topdown
And the hall of nanotechnology, the bottom
Technology. Tiny on the nanometer scale
This will be made with the material of the object
In nanotechnology. For easy understanding
Let's give an example. Remember,
You have a special kind of DNA
Required. So in bottom-up technology,
The smaller components of DNA
By that desired DNA
Will be created.
But only in nanotechnology
Not just technology, but top-down technology
The two will be combined.
Those of us who use computers
They know that every year
The price of computer is decreasing. Every year
Better than cheap
Computers are available. Actually this
With the computer
Related to nanotechnology.
The processor inside the computer,
Almost all of you are Intel processors
Have you heard the name? Of this processor
Inside are countless tiny little ones
Nanometer scale circuit. And
Nanotechnology is being used in it.
In the processor of the brick, on the silicon
The circuit is spelled by pattern
The current size is 100 nanometers.
In the next three years, its size will be 80
Nanometer. And in seven years
Will be 50 nanometers. Intel
Hopefully in 2010 they will be 30
Can bring in size. And
From today then this processor's
Will be halved. That day too
The day is not far away for you
The mobile will work on the computer
(Currently some such mobiles
Came on the market).
There are also computers
Hard disk. Information on this hard disk
The saving power is increasing day by day. This
Also used on hard disk
Being nanotechnology. Now
300 GB hard disk in the market
Available. But this matter today
Even 10 years ago it was imaginary
