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 ...

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/.

Ionic liquid crystals (ILCs) are emerging as interesting materials since they are expected to combine together the technological properties of ionic liquids (ILs) and liquid crystals (LCs). In this chapter, we will present a survey of the literature of the last 5 years, from 2005 to mid-2010 concerning ILCs.

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 ...

Metallomesogens based on d-block metals are extremely complex dynamic materials, proposed as good candidates in luminescent applications due to the combination of excellent photophysical properties with properties deriving from liquid crystals (self-healing, order and mobility).

Liquid Crystal Metamaterial Absorber Spatial Light Modulator for THz Applications
, 2014A terahertz (THz) spatial light modulator implemented with metamaterial absorbers (MMAs) functionalized with isothiocyanate‐based liquid crystals (LCs) is experimentally demonstrated. The device is designed to work in reflection mode and is arranged in a

Advances in gold nanoparticle-liquid crystal composites.
Nanoscale, 2014We present the advancement in the research of the dispersion of gold nanoparticles (GNPs) in thermotropic calamitic liquid crystals. The formation/behavior of surface plasmon resonance (SPR) in GNPs is briefly described.

Generation of the "perfect" optical vortex using a liquid-crystal spatial light modulator.
Optics Letters, 2013We introduce the concept of the perfect optical vortex whose dark hollow radius does not depend on the topological charge. It is shown analytically and experimentally that such a vortex can be approximately generated in the Fourier transforming optical ...
