SUMMARY:Molecular Adsorption at Metal and Metal Oxide Surfaces: From Corro
 sion to Catalysis via Functional Biomaterials - Dr Andrew Thomas\, Univers
 ity of Manchester

DESCRIPTION:The interaction of molecules with surfaces has a huge impact o
 n a massive range of technological applications from biomaterials to corro
 sion inhibitors and catalysts. Often the ordering and chemistry of an adso
 rbed molecule will have an influence on the success of a particular materi
 al in a particular application. Clearly\, the stability and strength of at
 tachment of molecules used to functionalise materials is critical to their
  success. However\, the orientation of molecules and changes to their elec
 tronic and molecular structure upon adsorption are also important factors 
 in the functionality of the materials and molecules.\n\nHere I will discus
 s two main areas of recent research by our group. Traditionally we have us
 ed synchrotron radiation to study the adsorption of simple molecules on si
 ngle crystal surfaces under vacuum conditions. Here I will describe some r
 ecent work on biomolecule adsorption with regard to the stability and chan
 ges in the electronic structure of the molecules upon adsorption. The seco
 nd half of the talk will focus on the ultrafast broadband vibrational sum-
 frequency spectroscopy (vSFS) instrument\, which we are developing in Manc
 hester and its application to problems in corrosion\, catalysis and pharma
 ceuticals. vSFS has the advantage that it is inherently surface sensitive 
 and thus surfaces can be studied under more technologically realistic cond
 itions including wet and buried interfaces.\n
