TL;DR: It is shown that appropriately designed bifunctional surfactants can direct the formation of zeolite structures on the mesoporous and microporous length scales simultaneously and thus yield MFI (ZSM-5, one of the most important catalysts in the petrochemical industry) zeolites that are only 2 nm thick, which corresponds to the b-axis dimension of a single MFI unit cell.

TL;DR: High-resolution details of cage and pore structures of periodically ordered mesoporous materials are reported, which reveal a highly ordered dual micro- and mesoscale pore structure.

TL;DR: The present approach using a zeolite structure-directing functional group contained in a surfactant would be suitable for the synthesis of other related nanomorphous zeolites in the future.

TL;DR: In this paper, the pore sizes of MCM-41 materials were determined using combined adsorption/powder X-ray diffraction (XRD) analysis, which showed that fine-tuning of pore size is easily a

TL;DR: In this article, the Fourier sum of the 3D-structure factors, both amplitudes and phases, which are obtained from Fourier analyses of a set of high-resolution electron microscope (HREM) images, was used for structure analyses of two MCM-48 crystals with different crystal morphologies.
