DESCRIPTION:Monolayers of amphiphiles have been established as most useful
  tools to study interac-tions and reactions at interfaces especially since
  new methods could be introduced to study them at microscopic and nanoscop
 ic level. Thus very peculiar and regular structures of domains of coexisti
 ng phases could be detected by optical microscopies that resulted from the
  competition of short range attractive and long range repulsive interfa-ci
 al forces. By surface X-Ray diffraction a wealth of mesophases were reveal
 ed in analogy to those of smectic liquid crystals. With newly developed me
 thods like FTIR \, X-Ray reflection and sum frequency generation one can n
 ow investigate many basic proc-esses in bio-and materials sciences as:\n\n
 - DNA interactions at interfaces - Enzymatic interactions at interfaces - 
 Ion binding and water structuring - Nanoparticle attachment as a basis of 
 emulsion stabilization.
