  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

  8. Nanoscience What makes it different?

  9. Nanoscience Did we work with any nanosized samples? Fewer than 70,000 atoms per particle?

  10. Nanoscience Type of Sample

  11. Nanoscience

  12. Nanoscience Motion and Position Descriptions

  13. Nanoscience

  14. Nanoscience Type of Sample

  15. Nanoscience Type of Sample

  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?

  18. Module Flow Chart Lesson 1.1 What is Nanoscience? What is Nanoscience? Examine and Compare size: macro, micro, sub-micro (nano) SI prefixes Lesson 1.2 What Makes Nanoscience so Different? What makes Nanoscience so different? Compare Newtonian and Quantum Chemistry Regimes as they relate to nanoscale science Lesson 1.3 What Makes Nanoscience so Important? Poster Assessment Lesson 2.1Extendable Solids Lesson 2.2Extendable Solids: Reactivity, Catalysis, Adsorption Lesson 2.3 Extendable Structures: Melting Point, Color Conductivity Lesson 3.1 Carbon Chemistry Lesson 3.2 Fullerenes and Nanotubes
