The size scales for atoms, molecules and cells
|
|
|
|
|
Atomic and molecular interactions with nanostructures are highly sensitive to differences in their physical sizes and chemical properties.
|
|
|
|
|
The same material in nanoparticle form is significantly more active for most chemical reactions because of the significantly larger surface area available for interaction as compare to the bulk material (e.g. activated carbon versus bulk carbon).

|
Earth Sciences: Water is a precious resource for society and its natural availability is scarce. Society’s ability to reclaim used water is important.
|
|
|
|
|
Chemistry: The reactions rates of atoms and molecules with other materials in liquid, such as nanoparticles, nanopores, and membrane filters, etc. is determined by the dynamics diffusion.

Scientific Investigation and Experimentation: Formulate explanations using logic and evidence.
