DESCRIPTION:The interaction of molecules with surfaces has a h
 uge impact on a massive range of technological app
 lications from biomaterials to corrosion inhibitor
 s and catalysts. Often the ordering and chemistry 
 of an adsorbed molecule will have an influence on 
 the success of a particular material in a particul
 ar application. Clearly\, the stability and streng
 th of attachment of molecules used to functionalis
 e materials is critical to their success. However\
 , the orientation of molecules and changes to thei
 r electronic and molecular structure upon adsorpti
 on are also important factors in the functionality
  of the materials and molecules.\n\nHere I will di
 scuss two main areas of recent research by our gro
 up. Traditionally we have used synchrotron radiati
 on to study the adsorption of simple molecules on 
 single crystal surfaces under vacuum conditions. H
 ere I will describe some recent work on biomolecul
 e adsorption with regard to the stability and chan
 ges in the electronic structure of the molecules u
 pon adsorption. The second half of the talk will f
 ocus on the ultrafast broadband vibrational sum-fr
 equency spectroscopy (vSFS) instrument\, which we 
 are developing in Manchester and its application t
 o problems in corrosion\, catalysis and pharmaceut
 icals. vSFS has the advantage that it is inherentl
 y surface sensitive and thus surfaces can be studi
 ed under more technologically realistic conditions
  including wet and buried interfaces.\n
