2D-3D representation (IMAGE)
Caption
On the left is a 3D representation, and on the right is a 2D cross-section. The pores in a material marketed as "fully porous" are unexpectedly blocked. The colored regions show where molecules adsorb and penetrate. The molecules should diffuse through the center, resembling Swiss cheese; however, they only access the outer surface, inefficiently leaving nearly 50% of the material unused.
