Surface-seeking domain

Cutting across the domains of the various techniques mentioned above, are the model calculations l These are theoretical attempts to predict the structure of surfaces from first principles. The model calculations differ from the theories mentioned in conjunction with the experimental techniques listed above, in that the former are not primarily designed to describe the interaction of a probe with a surface, although obviously much overlap exists. Thus the calculation of electronic states at surfaces seeks to describe from first principles a situation (the structure of the surface) that is analyzed experimentally by any of the techniques mentioned above, using external probes but some of these techniques also involve the motion of electrons througli the surface region this motion in turn is clearly related to the electronic structure of the surface, and so the first-principles calculation and the surface-analysis technique may have and often do have much in common. 

A surface-seeking peptide domain has low average hydrophobicity because of the presence of the hydrophilic amino acid residues, but it has relatively high hydrophobic...
