Liquid Crystals and Liquid Crystal Solutions Studied By NMR
1999Abstract Since the first publication on this subject in 1963, {NMR} in liquid crystalline systems has been a wide and active field of research in many branches of chemistry, physics, biology, and materials science. Indeed, thanks to the wealth of exploitable nuclei and interactions, {NMR} spectroscopy has revealed a powerful means of probing structure ...

Lab Chip, 2013
We report a dielectrically actuated liquid crystal (LC) pump. A small volume of LC forms a pillar-like droplet in a cylindrical hole which partially touches the bottom substrate with embedded interdigitated electrodes. By applying a voltage, the LC droplet can be largely stretched along the electrode direction by the generated dielectric force, which ...

Carbohydrate Polymers, 1984
Abstract Certain alkyl l-O and l-S glycosides with hydrocarbon chain lengths greater than hexyl have been shown to form thermotropic liquid crystals at temperatures between 60 and 100[ddot]C. These are believed to be members of a large class of alkyl and acyl carbohydrate mesogens which, apart from their intrinsic value as potentially useful solid ...

Supermolecular liquid crystals
Journal of Materials Chemistry, 2005In this article we review recent work on the development and study of the properties of self-organising supermolecular and supramolecular materials, that are in size comparable to small proteins. We take the concept of the creation of dendritic liquid crystals, and apply it to the creation of new materials with single identifiable entities, so that ...

Nucleation in liquid crystals and liquid crystal polymers
The Journal of Chemical Physics, 1991A 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
1993Liquid 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
2014Liquid 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, 1976The 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 ...

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 ...
