摘要：

Circular or columnar orientations of mesoporous silica can be selectively prepared by tuning the silica-to-surfactant ratio and the humidity during the synthesis of the mesoporous material within the regular larger channels of anodic alumina membranes. The transmission electron microscopy image shows the circular orientation of these highly ordered hexagonal mesostructures. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH £ Co. KGaA.
