DESCRIPTION:A growing demand for enantio-pure chemicals in bio-technologie
 s and drug manufacturing makes enantio-selective heterogeneous catalysts h
 ighly desirable. As a consequence\, the last decade has seen a dramatic in
 crease in research into chiral surface systems. Achiral surfaces can be mo
 dified with chiral organic molecules to create enantio-selective reaction 
 environments. We use synchrotron-based spectroscopies\, such as XPS and NE
 XAFS\, alongside LEED and temperature-programmed desorption to characteriz
 e the thermal stability\, bond coordination and orientation of modifier mo
 lecules on achiral and intrinsically chiral model catalyst surfaces. The t
 alk will concentrate on small chiral amino acids (e.g. alanine\, serine) o
 n Cu and Ni surfaces.
