John writes in with the latest science podcast for the UVA Virtual lab… –
“I’ve got a new presentation on how scanning tunneling microscopes work. STMs are the nanoscientist’s premiere tool for “seeing” individual atoms. Their invention was the subject of the 1986 Nobel Prize in Physics. But they have now become so simple and small that we are using them in a freshman “Introduction to Nanoscience” class here at the University of Virginia. The webpage version also links to a presentation on closely related “Atomic Force Microscopes” (AFMs).” – Link & iTunes.
