Explain how surface area to volume ratio is important for nanostructured materials.

Answer :

I. A parameter that determines functioning of a nanomaterial is the surface area (SA) to volume (V) ratio.

II. The greater the surface area of the nanomaterial, greater is the reactivity.


III. Due to difference in surface area to volume ratio different materials show different physical properties at the nanoscale.


IV. The size and shapes of all nanostructures are dependent on their physical properties.


V. Due to large surface area to volume ratio, friction and striking effects are prominent in nanomaterials.
