What Is‘Nano’

technology

NANOTECHNOLOGY

REVOLUTIONARILY VERY BIG (SMALL) THING

What is Nanotechnology?“Nanotechnology is the

art an science of manipulating matter at then

Nanoscale”.

NANO-TECNOLOGY IN RECENT YEARS IT

HAS BECOME ONE OF THE MOST IMPORTANT AND EXCITING FOREFRONT FIELDS IN PHYSICS,CHEMISTRY,BIOLOGYAND ENGINEERING AND

TECHNOLGY. IT IS LIKELY TO

PROVIDE MANY BREAKTHROUGH THAT WILL CHANGE THE DIRETION OF TECHNOLGICAL ADVANCES.

The term "nanotechnology" was defined by Tokyo University of Science Professor Norio Taniguchi in a 1974 paper as follows:

"'Nano-technology' mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or by one molecule."

WHATIS

‘NANO’ SCALE

NANOSCALE

Nanotechnology is the understanding and control of matter at dimensions of roughly 1 - 100 nanometers, -9 10 meter where unique phenomena enable novel applications.

A NANOMETER

is…one billionth of a

meter

NANO MATERIALS

“’NANO-MATERIALS’ could be defined as those materials which have structured components with size less then 100nm

at least in one dimension.”

Materials that are nanoscale in one dimension are layers, such as thin films or surface coatings.

Materials that are nanoscale in two dimensions include nanowires and nanotubes.

Nanotechnology is ubiquitous and pervasive. It is and emerging field in all areas of science, engineering and technology. Some are as given.

ADVANTAGESOF

‘NANO’TECHNOLOGY

MaterialWith NT, we can create unique

materials and products which are:

Stronger

Lighter

Durable

Precise

Industrial

Computers can become a billion times faster and a million times smaller

Automatic Pollution Cleanup

MedicalEnd of Illnesses (i.e. cancer, heart disease)

Universal Immunity (i.e. aids, flu)

Body Sculpting (i.e. change your appearance)

Disadvantages

Loss of jobs (in manufacturing, farming, etc)

Carbon Nanotubes could cause infection of lungs

Atomic weapons could be more accessible and destructive

Future of

National Science and Technology Council (USA) claims that:“Nanotechnology is an enabling

technology that will change the nature of almost every human-made object in

the next century.”

• Nanotechnology with all its challenges and opportunities will become a part of our future.

• The researchers are optimistic for the products based upon this technology.

• Nanotechnology is slowly but steadily ushering in the new industrial revolution.
