Validation of SCFT Predictions
Being a statistical thermodynamic model, the approach described above also
gives access to a number of unique features of the system. For example, it can
predict the fraction of water molecules bound to the lipid polar head and those
that are free: Both classes of molecules can be predicted in a statistical way as
a function of temperature and composition. Figures 1.8a and 1.8b show the
