Research in the nanoparticles area is giving very promising results, but there are very few current applications of nanoparticles. Heat transfer properties can be improved by incorporation of a very small volume fraction of nanoparticles in a liquid phase. Nevertheless, there is no definitive explanation yet for this phenomenon. The possibility to enhance mass transfer with nanoparticles was tested in this study. Two kinds of nanoparticles were used: solid non-adsorbent graphite particles and micelles, each of them corresponding to a possible mechanism for mass transfer enhancement. The results show that the diffusivity of organic solvents in water could be increased with the addition of ionic micelles, although more work needs to be conducted in this area.
