NanoscienceWhat Is It? What Makes Nanoscience so Different?
Nanoscience What units would be appropriate to measure the radii of atoms? Predict how many atomsyou think a medium-sized nanoscale particle might contain.
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?
Nanoscience 10-70,000 atoms 1 to 100 nm
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
Nanoscience Comparing Types of Samples
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
Nanoscience What makes it different?
Nanoscience Did we work with any nanosized samples? Fewer than 70,000 atoms per particle?

Nanoscience sometimes are not sure WHAT they are!
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?
