1. ABCs of Nano – a big picture of nanoscience, nanotechnology and nanoengineering Dawen Li, Shoieb Shaik, Scott Wehby June 22, 2015

2. Is It Small Enough?

3. Magic Nanoscale (1 to 100nm) Why nanoscale? Novel material properties and phenomena only observed in the nanoscale world. Impact our daily life in all areas, such as healthcare, environment, food, and energy.

4. How Small Nano Is?

5. Nanoscience, Nanotechnology, and Nanoengineering

6. Increase of Surface Area by Cutting

7. Surface Area to Volume Ratio

8. Percentage of Surface Atoms (3D)

9. Nanoengineering with Surface Effect

10. Nanoparticle Size/Shape versus Color

11. Interaction at Nanoscale At macroscale, gravitational force is usually dominant. At nanoscale, atomic force, particularly electrical forces are generally governing.

12. Atomic Force for Imaging Forces (van der Waals) between tip and surface depends on the tip height

13. Organized Structure from Self-Assembly

14. Electron Beam for Nanofabrication

15. Electron Beam for Imaging

16. Element Identification

17. Have Fun with Nano Products Nonstick umbrella, stain-free coating ! Strong adhesion tape ! Strong automobile tires from rubber/carbon nanotube composite!

18. Review Questions  How small is small? What is the nanometer size?  Why Nano is a magic scale?  In your words describe the difference between nanoscience, nanotechnology, and nanoengineering.  What is the size effects in terms of surface to volume ratio and quantum confinement of nanoparticles?  Give some examples for application of nanopowders?  Can self-assembly happens at macroscale?  What tools can be used for nanofabrication and imaging?  List a few nano-products related to our daily life?
