WebWhile the ensuing average nematic order is approximately the same as that found for spatially uniform solutions of Eq. 3, the local nematic order is much higher within the … WebJan 25, 2012 · Figure 8 The calculated phase diagram in the (α, r ¯ 0) plane for the representative case d = 2.5.In region I, there is a simultaneous nematic and magnetic first-order transition. In region II, the two transitions split, but the nematic transition remains first order, while the magnetic transition becomes second order.
Thermal hysteresis in the nematic order of a PCH-3 liquid crystal
WebOther articles where nematic phase is discussed: liquid crystal display: Electro-optical effects in liquid crystals: LCDs utilize either nematic or smectic liquid crystals. The … In a nematic phase, calamitic organic molecules lack a crystalline positional order, but do self-align with their long axes roughly parallel. The molecules are free to flow and their center of mass positions are randomly distributed as in a liquid, but their orientation is constrained to form a long-range directional order. See more 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 … See more A large number of chemical compounds are known to exhibit one or several liquid crystalline phases. Despite significant differences in … See more Lyotropic liquid-crystalline phases are abundant in living systems, the study of which is referred to as lipid polymorphism. Accordingly, … See more Examples of liquid crystals can also be found in the mineral world, most of them being lyotropic. The first discovered was vanadium(V) oxide, by Zocher in 1925. Since then, few others have been discovered and studied in detail. The existence of a true See more In 1888, Austrian botanical physiologist Friedrich Reinitzer, working at the Karl-Ferdinands-Universität, examined the physico-chemical properties of various derivatives of cholesterol which now belong to the class of materials known as cholesteric liquid … See more The various liquid-crystal phases (called mesophases) can be characterized by the type of ordering. One can distinguish positional order (whether molecules are arranged in any sort of ordered lattice) and orientational order (whether molecules are mostly pointing in … See more Anisotropy of liquid crystals is a property not observed in other fluids. This anisotropy makes flows of liquid crystals behave more differentially than those of ordinary fluids. For example, injection of a flux of a liquid crystal between two close parallel plates ( See more lhirwf30

Surowiec, Shawn W. Walker. We present an analysis and numerical study of an optimal control problem for the Landau-de Gennes (LdG) model of nematic liquid crystals (LCs), which is a crucial component in modern technology.
