Nanoadsorbents

I used Prezi for my main seminar in M.S program of nanochemistry. As always slides are not self-sufficient. I emphasized on "why we go small?" and "Why Nanoadsorbents are better?" The last slides are my favorites, Woks of M.C Escher and finally The Godfather and a straw man. If anybody could get my final message in final slide, I would be really blessed.
