1 The role of curvature in silica mesoporous crystals by Keiichi Miyasaka, Alfonso Garcia Bennett, Lu Han, Yu Han, Changhong Xiao, Nobuhisa Fujita, Toen Castle, Yasuhiro Sakamoto, Shunai Che, and Osamu Terasaki Interface Focus Volume 2(5):634-644 October 6, 2012 ©2012 by The Royal Society

2 A coloured representation of a reconstructed electrostatic potential map for the typical cage- type SMC SBA-1. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

3 (a) Plot of the Helfrich energy density versus the potential level c. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

4 Colour-coded distribution for ΔH and K on the determined ISs represented within a cubic unit cell: (a) as-syn-MCM-48, and (b) cal-MCM-48. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

5 Colour-coded rendering for K distribution on respective ISs of cage-type SMCs. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

6 Typical plot of conductance versus time for the system N-lauroyl-glutamic acid C12GlutA/H2O/APES/TEOS at RT. Initially, the surfactant and distilled water are mixed until no changes in the conductance are observed. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

7 (b) SEM images of trapezoidal icositetrahedron particles, observed in mesoporous material synthesis using the N-lauroyl-alanine anionic surfactant, using P123 as a dispersant. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

8 TEM images of elongated particles prepared using the N-lauroyl-alanine anionic surfactant, using P123 as a dispersant; images are viewed along (a) [311], (b) [100], (c) [111] and (d) [531] orientations. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

9 TEM images for SMC particles capturing the transitions between (a) p6mm to Iad, and (b) Iad to Pnm structures. Keiichi Miyasaka et al. Interface Focus 2012;2:634-644 ©2012 by The Royal Society

10 (a) TEM images of the intergrowth of p6mm and Pnm taken along the [110]cubic axis, (b,c) intergrowth of p6mm and Iad taken along the [111]cubic axis, (d) the Pnm sphere with icosahedral hollow, and (e) the actual g value distribution of the Pnm and Iad stru...
