WHERE THE RUBBER MEETS THE ROAD
A new technique reveals microscopic details of the interface
between two surfaces that are in contact. It uses high frequency
sound or pulses of heat to probe the interface, which is
inaccessible to conventional microscopes. The technique, reported
in the December Physical Review B, could be a valuable tool for
polymer scientists and biologists alike.
