1. NanoscienceWhat Is It? What Makes Nanoscience so Different?

2. Nanoscience What units would be appropriate to measure the radii of atoms? Predict how many atomsyou think a medium-sized nanoscale particle might contain.

3. Nanoscience 2 nm 1 nm • 5nm • How many atoms with a radius • of 5 x 10-2 nanometers: • Would fit on one 5 nm edge of this nanoparticle? • Would this nanoparticle contain?

4. Nanoscience 10-70,000 atoms 1 to 100 nm

5. Nanoscience Read this equation C(s) 1 atom of Carbon +O2(g) Plus 1 molecule of Oxygen CO2(g) 1 molecule of Carbon dioxide → yields

6. Nanoscience Comparing Types of Samples

7. Nanoscience Read this equation C(s) 1 mole of Carbon atoms +O2(g) plus 1 mole of Oxygen molecules CO2(g) 1 mole of Carbon dioxide molecules → yields

16. Nanoscience sometimes are not sure WHAT they are!

17. Making Connections • Compare nanoparticles to atoms/ molecules and macrosamples (Number of Units/Sample, Size, Regime). • What types of instruments do you think are needed to investigate nanoparticles?
