Chapter 1Introduction

Zhou, Shuang

Pages: 1 –12

[Lyotropic chromonic liquid crystals (LCLCs) are an emerging class of liquid crystals that have shown profound connections to biological systems in two aspects. First, the assembly process of the chromonic aggregates is essentially the same as DNA oligomers and other super-molecular assemblies of...

Chapter 2Elasticity of Lyotropic Chromonic Liquid Crystals Probed by Director Reorientation in Magnetic Field

Zhou, Shuang

Pages: 13 –31

[Using a magnetic Frederiks transition technique, we measure the temperature and concentration dependences of splay K1, twist K2, and bend K3 elastic constants for the lyotropic chromonic liquid crystal sunset yellow formed through noncovalent reversible aggregation of organic molecules in water....

Chapter 3Ionic-Content Dependence of Viscoelasticity of the Lyotropic Chromonic Liquid Crystal Sunset Yellow

Zhou, Shuang

Pages: 33 –49

[A lyotropic chromonic liquid crystal (LCLC) is an orientationally ordered system made by self-assembled aggregates of charged organic molecules in water, bound by weak non-covalent attractive forces and stabilized by electrostatic repulsions. We determine how the ionic content of the LCLC,...

Chapter 4Elasticity, Viscosity, and Orientational Fluctuations of a Lyotropic Chromonic Nematic Liquid Crystal Disodium Cromoglycate

Zhou, Shuang

Pages: 51 –75

[Using dynamic light scattering, we study orientational fluctuation modes in the nematic phase of a self-assembled lyotropic chromonic liquid crystal (LCLC) disodium cromoglycate and measure the Frank elastic moduli and viscosity coefficients. The elastic moduli of splay...

Chapter 5Living Liquid Crystals

Zhou, Shuang

Pages: 77 –92

[Collective motion of self-propelled organisms or synthetic particles, often termed “active fluid,” has attracted enormous attention in the broad scientific community because of its fundamentally nonequilibrium nature. Energy input and interactions among the moving units and the medium lead to...

Chapter 6Summary

Zhou, Shuang

Pages: 93 –95

[Lyotropic chromonic liquid crystals (LCLCs) represent a novel type of liquid crystals formed by self-assembly of disk-shape molecules in aqueous environment. The underlying physics that governs the anisotropic elastic and viscous properties of such materials is fundamentally different from that...
