    • Note that only over some, as yet not well defined, range of solids concentration can an increase in Φ be considered an increase in the "strength" of the quenched disorder. In reality, the surface interactions between the material filling the voids and the solid surfaces are dictated by the materials themselves and remain constant. Since liquid crystals are quite "soft" materials elastically, the quenched state of molecules at a surface decays relatively slowly away from the surface. Thus, a point will occur where p < 1 and yet everything between the surfaces can be considered quenched. In general, increasing O for large values of Φ only increases the extent of the surfaces and so the extent of the disorder but not its strength.

    • s=0.1, the number density of smectic domains is growing much faster than the number density of voids indicating the stronger disordering effects of the silica gel for these concentrations.
