4 important questions on Nanotechnology

What is nano science?

The study of small particles between 1 and 100 nanometers in size.

Why may nanoparticles have different properties than those of the same materials in bulk?

This arises because nanoparticles have a high SA:V with a high percentage of their atoms exposed at their surface.

What may nanoparticles result in?

smaller quantities of material, such as catalysts, being needed for industrial processes.
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding
Discover Study Smart

What is a benefit and risk of nanoparticles?

B- could improve many aspects of modern life
R- need more research, large SA makes them flammable

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
