Figure 1: A sketch of the L3 phase liquid crystal structure, derived from electron microscopy
done on freeze fractured samples, as well as theoretical considerations. The pore diameters
are uniform, but are randomly interconnected in all three dimensions resulting in short range
order with long range disorder. The bilayer forming the liquid crystal can then be templated
by a silica layer to capture the original liquid crystal structure as solid silica gel. (Source:
