Mesoporous materials, with typical pore sizes of a few nanometers, are complementary to zeolites, which have smaller pores and thus can only take up molecules up to a certain size. However, large-scale applications of mesoporous materials often require alignment of the pores over macroscopic length scales, which has been difficult to achieve. Tolbert et al. (p. 264) have devised a strategy whereby the precursor material, a liquid crystal, is aligned in a magnetic field; the alignment is preserved during the processing stages, resulting in a material with macroscopically aligned mesopores.
