Textures of liquid crystals
Webisotropic liquid state, the molecules move randomly and rotate freely about all possible directions (see Fig. I.1d). Thus, liquid crystals (LCs) have been defined as “orientationally ordered liquids” or “positionally disordered crystals” that combine the properties of both the crystalline (optical and electrical anisotropy) WebLiquid Crystals Research Group Liquid Crystals Research Group Research in the liquid crystal group involves the design, synthesis and characterisation of novel liquid crystals which exhibit new types of phases having remarkable properties.

Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many types of LC phases, which can be distinguished by their optical properties (such as textures).
