In this edition of SmallTalk, we hear from the man who builds the world�??s smallest vehicles. He calls them �??nanocars.�?? Dr. Jim Tour, a chemist at Rice University, tells us about his nanocars and how he thinks they might lead to nano-sized factories. We�??ll also hear from University of Florida graduate student Diane Hickey, who will tell us some of the interesting reactions she�??s run into when explaining nanotechnology. And we�??ll play our Nano News or Nano Nonsense quiz!
