    • Although we did not capture a separate stable ripple phase in our system, this ripple structure would provide a reasonable explanation of the intermediate structure observed in Fig. 2B. The ripple phase has been observed in many lipid systems (24) and can include macroripples with wavelengths of ∼ 100 nm (25). The slow neutralization strategy is necessary to leave enough time for the soft layer containing the hexagonal phase to bend.

    • It has been reported by Z. Luan et al. [J. Chem. Soc. Faraday Trans. 91, 2955 (1995)] that the crystal size of MCM-41 is reduced after incorporation of aluminum into the structure. In our case, this is reflected in shorter and thinner tubules when aluminum is incorporated into the framework.
