Many technologies are based on surface interactions, including:
Definition: Amount of surface area per unit volume of an object
surface area:volume or
Ex: S/V of a cube (with side a = 1 cm)
Nanomaterials have a large number of surface atoms and thus a large surface-to-volume ratio.
Fraction of the atoms on the surface
Compare S/V of carbon nanomaterials to other forms of carbon
For example: Diamond vs Carbon Nanotubes.
Density H2O = 1 g/mL
H2O = 18 g/mol
