Mesoporous films with biaxial, “single-crystalline” arrangements of spherical pores are obtained by “evaporation-induced self-assembly” (EISA) in work reported by Torsten Brezesinski, Markus Antonietti, and Bernd Smarsly on p. 1074. The films are dip-coated onto a sublayer with sufficiently different surface tension and a specific nanoscale periodicity. Low adhesion to the sublayer surface results in a relatively small number of nucleation sites and a uniform orientation of the evolving mesostructure in the toplayer.
