TRANSCRIPT
• CNT’s are the alloptropes of carbon with a cylindrical nanostructure.
• These have been constructed with length to diameter ratio upto 28,000,000:1.
• APPLICATIONS:-
2. To make bullet proof clothes.
3. In electric circuits.
4. In solar cells.
5. In paper batteries.
6. In NRAM (nano RAM).
RECENT DEVELOPMENT :2. In may2005, a sensor
is developed to detect different compounds in air.
3. In 2007, a radio receiver consisting of a single nanotube is demonstrated.
RECENT DEVELOPMENT :
3. In 2008, it is shown that a sheet of nanotubes can operate as a loud -speaker if alternanting current is applied.
With NT, we can create unique materials and products which are:
– Stronger– Lighter– Cheaper– Durable– Precise
– Computers can become a billion times faster and a million times smaller
– Automatic Pollution Cleanup
– Manufacturing at almost no cost
– End of Illnesses (i.e. cancer, heart disease)
– Universal Immunity (i.e. aids, flu)
– Body Sculpting (i.e. change your appearance)
– Loss of jobs (in manufacturing, farming, etc)
– Carbon Nanotubes could cause infection of lungs
– Oil & Diamonds could become worthless
– Atomic weapons could be more accessible and destructive
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.”
