Episode 13: The Nanoscale

Nanocrystals copyright Felice Frankel

You’ve heard the hype—but what’s nanotechnology really all about? Today’s show is an investigation into the current reality and the future potential of nanotechnology. In an interview with CHF’s Chi Chan, Harvard University chemist George Whitesides explains how nanofabrication works, what it has to do with chemistry, and what new developments we should expect to see in the next five years. In our Mystery Solved! segment, Jennifer Dionisio uncovers the tiny secret behind the legendary sharpness of Damascus steel. The Element of the Week: Carbon.
