For certain metal oxides (e.g., MoO3) ordered mesoporous films can be obtained with the nanocrystals in the pore walls being uniformly oriented with respect to the substrate by applying evaporation-induced self-assembly followed by heating. This surprisingly facile process, described by Smarsly and co-workers on p. 1827, works on different polar substrates (glass, metals, etc.) for oxides with anisotropic unit cells, based on the interaction with surfactants during nucleation (“soft-epitaxy”).
