Nucleation in liquid crystals and liquid crystal polymers

The Journal of Chemical Physics, 1991
A nematic mixture that undergoes a first-order phase transition to an ordered state is considered. The dynamics of the phase separation in terms of a theory based on a time-dependent Landau–Ginzburg equation is described. The laws of growth and dissolution for isotropic and anisotropic droplets are discussed.

Polymer liquid crystals-liquids or crystals

1993
Liquid crystals belong to a class of materials which were first described over a hundred years ago as characterising a state of matter intermediate between that of a crystal and a liquid. The light microscopic textures which are observed in these “ordered liquids” are very characteristic and have been described in many text books /1/.

Liquid Crystals and Liquid Crystal Displays

2014
Liquid crystal displays are used in a wide range of consumer goods, for example, flat panel televisions, smartphones, notebook computers and in-vehicle navigation displays. The development and uses for liquid crystalline materials in electronic displays is described in this chapter, with an emphasis on publications from the patent literature, a primary

Liquid crystals for magneticians ferroelectric liquid crystals

IEEE Transactions on Magnetics, 1976
The rapid development of research on the physics of liquid crystals in recent years is largely due to the application of knowledge, ideas, and experimental techniques from various aspects of solid state physics to these unusual materials. For those studying phase changes, response to external fields, and defect structures in liquid crystals, analogies ...

Mineral liquid crystals

Colloid Journal, 2017
The contemporary state of studying mineral liquid crystals has been analyzed. Such crystals are lyotropic aqueous or water–organic colloidal solutions, the dispersed phases of which are represented by nano- and microsized crystalline particles. The methods of production, structure, and physicochemical properties of these systems, as well as the ...

Pumping Liquid Crystals

Physical Review Letters, 1995
We observe mass pumping of a ferroelectric smectic-C liquid crystal induced by an applied ac voltage. The flow is unidirectional, reflecting the chirality of the system. An elastohydrodynamic model of the smectic-C phase is used to explain the observations.

LIQUID CRYSTAL MATERIALS AND LIQUID CRYSTAL DISPLAYS

Annual Review of Materials Science, 1997
▪ Abstract  Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex ...

Defects in Liquid Crystals

Reports on Progress in Physics, 1975
Defects are local breakings of symmetry in an ordered medium. The physics of defects has long been reduced to the study of dislocations in solids, and to the main physical phenomena they are responsible for, like plastic deformation. Dislocations break translational symmetries.
