Complex fluids composed of several pseudophases with a liquid-liquid interface (emulsions, macroemul-sions, cells, liposomes) or liquid-solid interface (suspensions of silica, carbon black, latex, etc.) can, from a dielectric point of view, be considered as classical heterogeneous systems. Several basic theoretical approaches have been developed in order to describe the dielectric behavior of such systems. Depending on the concentration, the shape of the dispersed phase, and the conductivity of both the media and disperse phase, different mixture formulas can be applied to describe the electric property of the complex liquids (11-15). 

The second selected example to illustrate the combined VASP/solid-state NMR/GIPAW approach is the characterization of the phospholipid/silica interface in silica-coated liposomes [29]. In such a system, one can distinguish two families of phosphate sites present in the lipid bilayer inner sites in interaction...
