Nano Technology

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

Single

Introduced one meter. They

Of the earth

One of the 40,000,000th part of the circumference

Share one

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.

1893

Introduce it by law in France

Is.

The definition of this meter in 1960

Change

Is done. Krypton 6's orange

The wavelength of radiation

1,650,73.63

One part is called a meter.

1983

Re-define the meter in the year

Is changed, current

By definition, light in the air

Speed

299,792,456 to one part

Meters

Is called. 1,000,000,000 of these meters

(100

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

Says nanotechnology.

The meter unit is our daily routine

Involved in life. Home

This meter of furniture we all measure

Single. Before World War II

Until

Electronics in millimeter scale

Fineness was measured. Small of millimeters

A time to think about something

There was not. But World War II ended

To be

Later, one new in science and technology

Of the era

The beginning is. The semiconductor is his journey

The beginning

Did. And the beginning of it is the transistor

With discovery. Then the micrometer

Single

Our thinking started with.

It can be said that the journey has begun,

Microtechnology.

Of

Later technology started advancing

Extreme

At speed. Various things, of which

In television, radio, fridge

Etc. etc. And

How to make it smaller

With that the fierce war began.

No

All of this is how small the company is

Enjoyable

Things are ours

Can reach, his

The competition began. And all this

The thing is possible, semiconductors

Related to the welfare of technology. First

Direction

The size of the radio or TV

We will get a smile now. So much

Large

Big things people used to do

How?

That question may come up.

But

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

Discovery

STM (Scanning Tunneling)

Microscope) This

Visit the molecule structure with the instrument

Possible.

The invention of this device

Nanotechnology

Who has been able to make it a reality.

How this STM works. On this device

Too

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

Of course

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

People

The way it has come so far

This

The impossible was made possible by AFM.

STM

In this case tunneling power

Is worked with and with AFM

Fine

It is possible to see the molecular structure with pins.

Richard January 29, 1959

Feynman California Institute

Held in off-technology

American

At a meeting of the Physical Society

There's

Plenty of Room at the Bottom

One

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

Almaden

Don Eigler at the Research Center and

Erhard

Schweizer IBM with 35 Xenon molecules

Of

Created the logo. That day

Arrange the first molecule as desired

Something

It is possible for people to create.

Today

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

Just because of the difference in molecular structure

Diamonds

The hardest product in the world anymore

The tip of a coal or pencil is soft.

Cornell University in 1999

Wilson

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

Lots

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

Hall

Bottom to top.

Topdown

The method is to cut any thing short

He is given a specific shape.

This

The field is usually etching

The process is related. And downtown

Hall

With small things of small size

Large

To make any thing. Ours

Current Electronics Hall, Topdown

Technology.

And the hall of nanotechnology, the bottom

Technology. Tiny on the nanometer scale

Tiny

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,

That

The smaller components of DNA

Combination

By that desired DNA

Will be created.

But only in nanotechnology

বটমটুটপ

Not just technology, but top-down technology

Use

The two will be combined.

Those of us who use computers

They know that every year

The price of computer is decreasing. Every year

Previous

Better than cheap

Efficiency

Computers are available. Actually this

With the computer

Related to nanotechnology.

The processor inside the computer,

Almost all of you are Intel processors

Of

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

Size

Will be 50 nanometers. Intel

Hopefully in 2010 they will be 30

Nanometer

Can bring in size. And

From today then this processor's

Size

Will be halved. That day too

The day is not far away for you

The mobile will work on the computer

Like

(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

Outside.
