SUMMARY:Unravel buried soft interfaces: From lipid bilayers to responsive 
 polymer brushes - Wuge Briscoe ( University of Bristol)

DESCRIPTION:Many biologically and industrially relevant interfaces are dec
 orated with polymers and surfactants. Understanding the structure of such 
 soft interfaces is thus critically important. Using synchrotron X-ray refl
 ectivity (XRR)\, we have studied self-assembled surfactant/lipid layers at
  the mica-water interface using a “bending mica” method\, and observed
  layer structural characteristics which differ from those widely reported 
 using AFM imaging. We have also used the XRR technique to study the collap
 se of thermoresponsive polymer brushes\, critically examining the validity
  of two competing structural models for such a brush collapse process.
