Mixing Mechanics: Adding nanopowders to liquids

Today's nanopowder applications vary widely. Inkjet inks that require very fine droplets incorporate nanoparticle pigments. Powdered drink mixes contain nanoparticles that make the powder reconstitute faster and more completely. Pharmaceuticals contain nanoparticles that increase dosage effectiveness with a smaller quantity of the costly active ingredient. Construction materials are stronger or more elastic because of the nanoparticles they contain.

The value of using nanopowders is the greater surface area they have in comparison to larger particles. Their greater surface area means that the material's innate characteristics are magnified many times. So, for example, you can produce a much stronger material by adding a small quantity of your strengthening ingredient in nanopowder form than by adding a larger quantity of the same ingredient in micron or larger-size particles.
