	abstract = {The diffusion of both water and surfactant components in aqueous solutions of the nonionic surfactant "C12E6"-which includes hexagonal, cubic, lamellar, and micellar mesophases-has been studied by pulsed-field-gradient NMR. Diffusion coefficients were measured in unaligned samples in all of these phases. They were also obtained in the hexagonal and lamellar phases in oriented monodomain samples that were aligned by slow cooling from the micellar phase in an 11.7 T magnet. Measured water and soap diffusion coefficients in the NMR-isotropic cubic and (high-water-content) micellar phases as well as diffusion anisotropy measurements in the magnetically aligned hexagonal phase were quantitatively consistent with the constituent structures of these phases being identical surfactant cylinders, with only the fraction of surface-associated water varying with the water-soap molar ratio. The values of the water and soap diffusion coefficients in the oriented lamellar phase suggest an increase in defects and obstructions to soap diffusion as a function of increasing water content, while those in the low-water-content micellar phase rule out the presence of inverse micelles.},

	abstract = {Structure organization of the cubic silicate species, Si8O208-(Si-8), by the cationic surfactant, CH3(CH2)(15)N(CH3)(3)(+), leads to mesophasic precipitates with layer or rod-based structures depending on the conditions of the precipitation. Further ordering of the structures of these precipitates has been achieved by acidic vapor treatment leading to ordered materials with cubic (MCM-48), lamellar, and hexagonal (MCM-41) mesostructures. For the first time, step-by-step structural transformations have been observed, which follow the-sequence given here, during vapor phase treatment: layered precipitate (L(0)) {\textendash}> cubic (V-1) {\textendash}> lamellar (L(1)) {\textendash}> hexagonal (H-1). These results strongly support a mechanism in which, under typical synthetic conditions, silicates and surfactants mutually organize into mesoscopic assemblies with geometries close to those of discs, rods,or spheres as determined by charge density matching and then these assemblies further condense into ordered lamellar, hexagonal, or cubic structures depending on the final reaction conditions. The present results also demonstrate that it is possible to achieve structure-tailoring and better framework ordering of these mesostructural materials.},
