2. 1) INTRODUCTION OF NANOTECHNOLOGY 2) HOW SMALL IS NANOMETER 3) WHY SMALL IS GOOD 4) PHYSICAL PROPERTIES OF NANOMATERIALS 5) MANUFACTURING OF NANOTECHNOLOGY 6) APPLICATION OF NANOTECHNOLOGY 7) EXAMPLE OF NANOTECHNOLOGY www.engineersportal.in

3.  Defination:- The science,engineering & technology related to the understanding & control of matter at the length scale approximately 1 to 100 nanometer. www.engineersportal.in

4.  Start with centimeter A centimeter is about the size of a bean  Now divide it into 10 equal parts Each part is a millimeter long. About the size of a flea.  Now divide that into 10 equal parts Each part is 100 micrometers long. About the size (width) of a human hair  Now divide that into 100 equal parts. Each part is a micrometer long. About the size of a bacterium.  Now divide that into 10 equal parts Each part is a 100 nanometers long. About the size of a virus.  Finally divide that into 100 equal parts. Each part is a nanometer. About the size of a few atoms or a small molecule www.engineersportal.in

5.  Faster  Lighter in weight  Cheaper  Require less space  More energy efficient www.engineersportal.in

6.  Copper is opaque substance become transparent.  Platinum is inert material become catalyst.  Aluminium is stable material become combustible  Silicon is insulator material become conductor. www.engineersportal.in

7. Manufacturing at the nanoscale or to get nanomaterial is called nanomanufacturing Two types of manufacturing 1)Top down 2)Bottom up www.engineersportal.in

8. 1)Top down:- It reduce large piece of material all the way down to nano scale. This process require larger amount of material. www.engineersportal.in

9. 2) Bottom up:- It creates products by putting together smaller piece. It is a self assembling of material. www.engineersportal.in

10.  Electronics  Health & Medicine  Transportation  Energy and Environment www.engineersportal.in

11.  Nanosensors are used for collecting,processing and communicate massive amount of data with minimum size,weight and less power consumption.  Smaller Transistor  Smaller Memory  Smaller Circuitry www.engineersportal.in

12.  Nano medicine has potential to improve diagnosis & treatment of cancer,aids,alzheimer & diabetes.  Nanofilter will help create impurity free drugs.  Nanotechnology that can regrow bone and organ. www.engineersportal.in

13.  Carbon based fibers which are 100 times stronger than steel and one sixth the weight.  Nanocoating of metallic surface provide super harding,low firction & corrosion protection.  Faster,cheaper & safer transformation. www.engineersportal.in

14.  Nanocrystal,nanofilter,nanosensor are being used for cleaning drinking water.  Nanomaterial based cosmetics are provide greater clearity and scan care. www.engineersportal.in

15.  Super computer  Energy storage batteries  Baseball bat Carbon nanotube baseball bat Shocks with silver nanopartical www.engineersportal.in
