Question

Why nanomaterials behave differently as compared to their bulk counterparts?

Answer 1

Answer:

Materials at the nanoscale have a greater surface area to volume ratio than their bulk counterparts. The relative concentration of under-coordinated surface atoms is thus greater for nanomaterials compared to their bulk form, which typically lowers their melting point and increases their reactivity.
