Continuous rotation of achiral nematic liquid crystal droplets driven by heat flux
Jordi Ignés-Mullol, Guilhem Poy, Patrick Oswald
Suspended droplets of cholesteric (chiral nematic) liquid crystals spontaneously rotate in the presence of a heat flux due to a temperature gradient, a phenomenon known as Lehmann…
Connectivity of the Hexagonal, Cubic, and Isotropic Phases of the CEO/HO Lyotropic Mixture Investigated by Tracer Diffusion and X-ray Scattering
Doru Constantin, Patrick Oswald, Marianne Impéror-Clerc +2
The connectivity of the hydrophobic medium in the nonionic binary system CEO/HO is studied by monitoring the diffusion constants of tracer molecules at the transitio…
Structural Transition in the Isotropic Phase of the CEO/HO Lyotropic Mixture: A Rheological Investigation
Doru Constantin, Éric Freyssingeas, Jean-François Palierne +1
We study the structural changes occurring in the isotropic phase of the C=EO/HO lyotropic mixture (up to 35% surfactant weight concentration) upon increasing the con…
High-frequency rheological behaviour of a multiconnected lyotropic phase
Doru Constantin, Jean-François Palierne, Éric Freyssingeas +1
High-frequency (up to rad/s) rheological measurements combined with light-scattering investigations show that an isotropic and multiconnected phase of surfactant mi…
Chirality-Biased Point Defects Dynamics on a Disclination Line in a Nematic Liquid Crystal
Andrzej Zywocinski, Katarzyna Pawlak, Robert Holyst +1
Chiral additives in the nematic liquid crystal can alter the dynamics of point defects moving on a disclination line. They exert a constant force on defects, leading to the bimodal…
Formation of disclination lines near a free nematic interface
Jordi Ignes-Mullol, Jean Baudry, Lubor Lejcek +1
We have studied the nucleation and the physical properties of a -1/2 wedge disclination line near the free surface of a confined nematic liquid crystal. The position of the disclin…
