Static and dynamic behavior of a nematic liquid crystal in a magnetic field. Part II : Dynamics
2014 The dynamics of the distortion of a well-oriented nematic liquid crystal film in a perpendicular field around the Freedericks critical field value is studied both theoretically and experimentally. The experimental thermal and optical techniques have already been used for the description of the equilibrium properties of the transition. Their use for the measurement of transition rates leads...
متن کاملZero-Field Nuclear Magnetic Resonance of a Nematic Liquid Crystal
appear which matched those observed by Sanchez and Spiro. Figure 9 shows the time development of the observed Raman spectrum at -0.8 V which at long times became the spectrum of high-spin Fe(I1). The time development of the spectroscopic changes at -0.8 V contrasts the instantaneous changes observed in the reduction of adsorbed hemin and instead tracks the slow reduction of the entire solution ...
متن کاملMicroscale locomotion in a nematic liquid crystal.
Microorganisms often encounter anisotropy, for example in mucus and biofilms. We study how anisotropy and elasticity of the ambient fluid affects the speed of a swimming microorganism with a prescribed stroke. Motivated by recent experiments on swimming bacteria in anisotropic environments, we extend a classical model for swimming microorganisms, the Taylor swimming sheet, actuated by small-amp...
متن کاملWork fluctuations in a nematic liquid crystal
The orientation fluctuations of the director of a liquid crystal are measured, by a sensitive polarization interferometer, close to the Fréedericksz transition, which is a second order transition driven by an electric field. Using mean field theory, we define the work injected into the system by a change of the electric field and we calibrate it using Fluctuation-Dissipation Theorem. We show th...
متن کاملNonequilibrium steady-state response of a nematic liquid crystal under simple shear flow and electric fields.
The effect of a dc electric field on the response of a nematic liquid crystal under shear flow has been investigated by measuring the shear stress response to an ac electric field used as a probe. It was found that both the first- and second-order responses do not vanish at high frequencies, but have constant nonzero values. The experimental results are in good agreement with calculations based...
