DOWNLOAD EBOOKLiquid crystals are known for their fascinating optical properties. This work describes the experiments on light scattering and theoretical calculations on nonlinear optics in liquid crystals. Light scattering is a powerful tool to study the viscoelastic response of liquid crystals which is an essential parameter for display industry. Both thermotropic and lyotropic systems were probed by light scattering. Thermal nonlinearities in cholesteric liquid crystals are described in this book and various surprising liquid crystal phase transitions in the presence of a laser beam are reported. The work described in the book is based on Ph.D. work carried out by Amit K Agarwal at the Raman Research Institute, India and all intellectual and other legal rights arising out of this work are owned by the Institute and they are acknowledged and protected.

DOWNLOAD EBOOKThis thesis describes lyotropic chromonic liquid crystals (LCLCs) with exotic elastic and viscous properties. The first part of the thesis presents a thorough analysis of the elastic and viscous properties of LCLCs as functions of concentration, temperature and ionic contents, while the second part explores an active nematic system: living liquid crystals, which represent a combination of LCLC and living bacteria. 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 biological origin. LCLCs thus provide an excellent model system for studying physical properties such as the elasticity and viscosity of these supramolecular assemblies. Second, LCLCs are biocompatible, thus serving as a unique anisotropic matrix to interface with living systems such as bacteria. This thesis deepens our understanding of both aspects. The noncovalent nature of chromonic aggregation produces the unique viscoelasticity to be found in LCLCs, which differs dramatically from that of traditional LCs. Anisotropic interactions between LCLCs and bacteria lead to fascinating phenomena such as the deformation of LCLCs with a characteristic wavelength determined by the elasticity of the LCLCs and the activity of the bacteria, orientationally controlled trajectories of bacteria and visualization of 24 nm flagella motion.

DOWNLOAD EBOOKLiquid crystal displays were discovered in the 1960s, and today we continue to enjoy the benefits of that fundamental discovery and its translation into a wide variety of products. Like liquid crystals, polymers are unusual materials, and have similarly enjoyed a great deal of research attention because of their vast applications and uses and compl
