Size bro Flashcards
1
Q
Does size matter
A
Materials with particle sizes between 1 and 100 nm are classified as
nanomaterials
Nanomaterials have different properties than materials of the same
composition with larger particle sizes. So, yes, size does matter!
2
Q
How do properties change with changing size of particles
A
Properties change as nanomaterials have a very large surface to volume ratio meaning their chemical reactivity is improved.
