Neutron and X-Ray Studies of Interfaces
In this lecture we will discuss how information about the interface morphology in complex heterogeneous media can be derived from scattering experiments. The practical systems we have in mind are high surface area aluminas which are used as bearers for catalysts and as components in LiI/ Al2O3 composites. The latter show enhanced Li-mobility, probably due to an interface reaction1. Other examples are minerals2, coals3 and carbon blacks4 for which evidence of fractal character of the interfaces has been presented.
