 Self-similar surfaces in foams?

Many applications of porous materials hinge on the specific surface area they can offer, e.g., catalysts.
However, the determination of such surfaces is often challenging, as internal surfaces show a marked roughness that involves length scales across many orders of magnitude (from Angstoms to micrometers). However, if such surfaces are self-similar, the surface area becomes a power law of the length scale. Foams are an excellent test bed to explore when self-similar surfaces form. The project aims at creating 3D model structures of foams and analyzing these foams in terms of their specific surface area and pore size distribution.
