Liquids, Crystals and Liquid Crystals
Physics Today, 1989In thinking about the states of condensed matter, we usually consider two extremes. At one extreme are crystalline solids, in which atoms form a perfectly periodic array that extends to infinity in three directions. At the other extreme are fluids or glasses, in which the atoms or molecules are completely disordered and the system is both ...

Photoalignment of Liquid Crystals by Liquid Crystals
Physical Review Letters, 2000We observed light-induced alignment of the nematic liquid crystal, 4, 4(')-n-pentylcyanobiphenyl (5CB), on a fused quartz. Irradiation of the adsorbed layer with polarized ultraviolet light produced homogeneous alignment in a 5CB-filled liquid crystal cell with the easy orientation axis perpendicular to the polarization direction.

Liquid Crystals Align Liquid Crystals
Japanese Journal of Applied Physics, 2002We have investigated the molecular orientation of a liquid crystal (LC), pentylcyanobiphenyl (5CB), evaporated on a rubbed polymer by means of polarized ultraviolet absorption spectroscopy and surface second-harmonic generation. The results unambiguously reveal that the in-plane anisotropy is diminishingly small before the molecules form a monolayer ...

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 ...

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 ...

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.

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 ...

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 ...
