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 struc-tures of domains of coexist
 ing phases could be detected by optical microscopies that resulted from th
 e competition of short range attractive and long range repulsive interfa-c
 ial forces. By surface X-Ray diffraction a wealth of mesophases were revea
 led in analogy to those of smectic liquid crystals. With newly developed m
 ethods 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\n-	Enzymatic interactions at interfaces\n
 -	Ion binding and water structuring \n-	Nanoparticle attachment as a basis
  of emulsion stabilization.\n
