Team teaching from a distance works for emerging nanotechnology field

It has been little more than 20 years since the discovery of buckyballs, hollow spherical molecules made entirely of carbon atoms, which serve as the starting point for this field of study. In 1996, Richard Errett Smalley won the Nobel Prize in Chemistry for the breakthrough. While there have been accomplishments at the pinnacle of academics in this emerging field, there is still a need for more accessible introductory curricula.

Hard evidence that gold nanoparticles exist in nature

The search for these natural but 'invisible' nanoparticles is important. If they can be proved to exist, the knowledge will help give us a deeper understanding of how gold can be transported and deposited by geological processes, and therefore help explorers to find new gold deposits in Australia.
