COVER C60 molecules encapsulated in a single-wall carbon nanotube peapod. In the background are the electron waves in this one-dimensional nanostructure, mapped with a scanning tunneling microscope (higher peaks represent higher tunneling conductance). Encapsulation of molecules is a viable route to tuning the electronic properties of carbon nanotubes, which form the heart of many proposed nanoscale devices. 828 [Image: D. J. Hornbaker and A.
