Program 20:  On the Surface  pdf

            How does the surface of a substance differ from its bulk?  Surfaces react with each other at the molecular level and are unique in the way in which they behave catalytically in chemical reactions.  The chemistry of surfaces falls into the province of a special brand of chemistry – surface science.
