Nano technology

just download and play slideshow.good animated video and gif animation is used and this slideshow contain data about nano technology and its application which you can easily understand.this is only for the education purpose which you can use for creating your ppt on nano technology.

1. NANO TECHNOLOGY Made By: HRITIK College: NIT surathkal , karnatak .

2. NANO & TECHNOLOGY Nano= A Nano metre is a unit of length in the metric system, equal to one billionth of a metre( 10 -9 ). Technology=Technology is an application of science used to solve problems

3. WHAT IS NANO TECHNOLOGY? Nanotechnology is science, engineering, and technology conducted at the nanoscale. which is about 1 to 100 nanometers .

4. Understand Nano

5. Tools used There are several important modern developments Atomic force microscope (AFM) Scanning Tunneling Microscope (STM)

6. Atomic force microscope (AFM) Scanning Tunneling Microscope (STM) how it is actually

7. Application Medical & drugs Defence and security Solar cells Cosmetics Electronics Nano Fabrics Aero Space Nano devices Nanotechnology Applications

8. Nanotechnology In Medical & Drugs (Cancer) Provide new options for drug delivery and drug therapies. Enable drugs to be delivered to precisely the right location in the body and release drug doses. Current treatment is through radiotherapy or chemotherapy.

9. Nanotechnology in Fabrics The properties of familiar materials are being changed by adding nano -sized components to improve performance. For example- Water and Stain repellent cloth Bullet proof jackets. Antimicrobial & antibacterial fabrics.

10. Nanotechnology in Electronics Nanoelectronics refer to the use of nanotechnology & electronic components ,especially transistors. Nanolithography is used for fabrication of chips. For eg - Nano Integrated Circuits Graphene screen

11. Nanotechnology In Defence & Security Lighter, faster aircraft which use less fuel. Cheap, small, and more effective weapons. Stronger, thinner and cheaper bullet-proof glasses. Submarines and planes that can go undetected by radar.

12. Nanotechnology In Aerospace Make lightweight spacecraft High Strength Composites. Sensors .   Self-healing plastic. Satellite, communication and radar technologies

13. Nanotechnology in Cosmetics and Skin Care Nanotechnology is being used in cosmetics to keep our skin more youthful and provide protection from harmful sunlight. For e.g - Blue Light Laser skincare technology treat pimples and scars. Sunscreen that uses zinc oxide nanoparticles to block ultraviolet rays. Skin creams that uses proteins to prevent aging of the skin. proteins are encapsulated in liposome nanoparticles.
