WebParanematic susceptibility. In the study of liquid crystals the paranematic susceptibility (Latin: susceptibilis "receptiveness") is a quantity that describes the degree of induced … WebNamely, a paranematic ordering favours parallel alignment of LC molecules, which breaks the isotropic symmetry imposed by the homeotropic anchoring condition. On the other hand, the coupling between cluster directors is relatively weak. Consequently, the orientational distribution function of cluster directors is expected to be isotropic if l N ...

Continuous Paranematic-to-Nematic Ordering Transitions of …

WebMar 17, 1986 · It is shown, within the context of Landau theory, that in uniaxial liquid crystal systems the isotropic-nematic Landau point lies at the intersection of three coexistence … WebWe predict that such membranes can acquire a non-zero paranematic order induced by the membrane curvature, which in turn produces curvature instabilities. We call the resulting paranematic order para-antinematic, since it is opposite on opposite sides of the membrane. We find phase transitions toward sponges (L3), tubules, or modulated “egg ... trade bloc business definition

The paranematic-speronematic phase diagram (τ, Λ).

WebThis field-induced phase is denoted paranematic phase, such that when the external field is turned off, the paranematic phase relaxes to the isotropic state. To predict plant cell … WebThe orientational order of the confined liquid crystals, quantified by the uniaxial nematic ordering parameter, evolves continuously between paranematic and nematic states, in contrast to the discontinuous isotropic-to-nematic bulk phase transitions. the ruff house ardmore pa
