Thermodynamics of Micellar Lyotropic Liquid Crystals
Aqueous lyotropic liquid crystals (LLCs) comprise a class of ordered morphologies formed by self-assembly of amphiphiles in water. LLCs assume a variety of concentration- and temperature-dependent structures including lamellae (bilayers), bicontinuous networks, hexagonally-packed cylindrical …

Structural studies of nonionic lyotropic liquid crystals
… resonance and x-ray and neutron scattering. The liquid crystalline phases have been characterized and their dimensional parameters determined. A phase diagram of C 16E06 has been produced covering the range of surfactant concentrations from 24 to 60% by weight. This system presented a nematic …

Direct Templating of Semiconductor Nanostructures With Lyotropic Liquid Crystals
Material growth in lyotropic liquid crystals has proven to be a very powerful methodology for the creation of nanoscopic features in mineral phases. Two distinct methodologies were studied---bulk templating and thin film templating. Bulk templating yields a powder of material containing the …

Synthesis, Characterization, and Utilization of Polyol Amphiphile Molecules
… amphiphiles are predictably hygroscopic, forming lyotropic liquid crystals upon exposure to water. The resulting lamellar and hexagonal mesophases were characterized by a variety of techniques including small angle x-ray scattering and polarized optical microscopy. Interestingly, the polyol …

Development of a novel cell traction force transducer based on cholesteryl ester liquid crystals. Characterisation, quantification and evaluation of a cholesteryl ester liquid crystal based single cell force transducer system.
… transducer system based on cholesteryl ester lyotropic liquid crystals (LCTFT) was developed to sense localised traction forces of human keratinocyte cell lines (HaCaTs), in which the length of the deformation line induced represents the intensity of the CTF exerted. The physical properties of …

Conjugated polymers and designed interfaces : conformational analysis and applications
… interface and the hydrocarbon-water interface in lyotropic liquid crystals. To expand this interfacial exciton migration to more generalizable interfaces, Chapter 4 will show the fabrication of oil-in-water emulsions and how exciton migration in oil-in-water emulsion can produce distinct …

Harnessing Light-Responsive Structural Control in Surfactant Assemblies
… materials. To create functional materials, lyotropic liquid crystals (LLCs) are ideal candidates due to their hierarchically-ordered nanostructures that are highly sensitive to their environment. LLCs are formed from the self-assembly of surfactants on the addition of a solvent and can be …
