What is a nanometer and why is size and scale important

What is a nanometer and why is size and scale important ?

  • Nano = dwarf in Greek

  • It is one billionth of a meter (1 x 10-9)

  • Properties of materials change at the nano level

  • a. melting point b. fluorescence c. conductivity d. chemical reactivity
