1. Materials Science Workshop Penn State University June 26 – July 1, 2005 Got Nano?

2. Nanoscience – The science of small. 1 nanometer

3. Really small. 150,000 meters 150,000 nanometers www.theproscope.com

4. Seeing nano-sized stuff: Atomic Force Microscope www.barrettresearch.ca

5. Seeing nano-sized stuff: Scanning Electron Microscope www.nottingham.ac.uk/ www.mos.org

6. Seeing nano-sized stuff: Modeling an AFM

7. Making nano-sized stuff: Nanowires An alumina disk is coated with a liquid Gallium Indium alloy. The coated disk is taped on a copper plate. The disk and copper are submerged in a nickel plating solution.

8. Making nano-sized stuff: Nanowires An AA-battery provides a current and allows the nickel to emerge from solution and pass towards the copper through the disk. The disk is then dissolved away, revealing…

9. Making nano-sized stuff: Nanowires Tiny nickel wires with a diameter of roughly 20 nm! (SEM images, by the way!)

10. Making nano-sized stuff: Solar Cell Anode dyed with Raspberry

11. Making nano-sized stuff: Solar Cell Cathode made from carbon from a flame. The anode and cathode are joined

12. Making nano-sized stuff: Solar Cell Iodine drawn in between the anode and cathode facilitates the flow of electrons when light strikes the solar cell.

13. Nanoscience in Action Controlling the Color of Glass

14. Nanoscience in Action Altering the Color of Liquids

15. Nanoscience in Action Waterproof Clothing
