[en] Countless technologies and chemical processes make use of nanoporous materials:
heterogeneous catalysis, including electrochemical reactions in fuel-cell electrodes,
adsorption separation processes, kinetically selective membrane processes, are but
a few examples. Nanopores are also relevant to natural processes as diverse as the
weathering of rocks and ion transport through biological membranes.[1] Small-angle
scattering of x-rays (SAXS) or neutrons (SANS) is one of the few experimental methods
currently available for the in situ analysis of phenomena in this type of materials at
the mesoscopic scale.[e.g. 2,3]
In this presentation, we briefly review some recent applications of small-angle
scattering to the in situ analysis of phenomena inside mesoporous solids. A particular
focus is put on the data analysis challenges, whereby the scattered intensity is
converted to real-space structures with nanometer resolution.
