Presentation Transcript

  1. NanoscaleScience and Engineering

  2. What is Nanoscale Science and Engineering? Engineering at the nanoscale is called Nanotechnology!

  3. How small is a nanometer?

  4. MACRO meter centimeter All these are still visible with your eyes. millimeter

  5. 6-8 µm micrometer (One-millionth of a meter) MICRO Nanoscale objects are 1,000 times smaller!!! These are smaller than you can see.

  6. NANO A nanometer is one billionthof a meter!! DNA 2.5 nm Viruses 3-50 nm Atoms <1 nm

  7. Nanotechnology The nanometer is extremelysmall. At the nanometer scale, many materials behave differently. We can use this new behavior to make newtechnologies.

  8. Nano in Nature

  9. Apparel with silver nanoparticles “Nano” all around us Tata Nano Babygear

  10. Things are different . . . Size really does matter! Bulk Nano

  11. Things are different . . . Size really does matter! Bulk Nano Nanoparticles interact differently with light.

  12. Nanotechnology in the Middle Ages Depiction of a forest glass shop from Sir John Mandeville's Travels, Dated 1420 – 1450. British Library, London

  13. Why Do We Care? Nanotechnology can improve how we live!

  14. 60-100 nm • Silver nanoparticles are used to kill bacteria in: • Athletic apparel • Socks • Refrigerators • Storage containers • Washing machines Gold nanoshells can target and destroy cancer cells

  15. “Printing” Nano-solar Panels

  16. Cities could be Power Plants!

  17. Carbon Nanotube Energy Transportation

  18. Coal Graphite Diamond Carbon Nanotube Carbon Atoms Rearranged

  19. But what about the risks?

  20. Think Like a Nano Scientist!

  21. Thank you! This project was supported by the National Science Foundation, NISE Net and OMSI.

  22. True or False? FALSE! TRUE! 1. A red blood cell is found on the nanoscale. 2. DNA is found on the nanoscale.

  23. True or False? TRUE! TRUE! 2. Nanotechnology can effect the way we move and produce energy. 1. Things on the nanoscalecan be found all around us in nature.
