Importance of interfacial interactions to access shear elasticity of liquids and understand flow induced birefringence from liquid crystals to worm-like micellar solutions

For both samples the evolution of El versus temperature is different. - For all the samples in the parallel direction, a single relaxation domain of the Debye type is

Effect of micellar flexibility on the isotropic-nematic phase transition in solutions of linear

Measurement of the birefringence induced in liquids by ultrasonic waves : application to the study of the isotropic phase of PAA near the transition

We examine the corrections to the liquid crystal mean field theory by generating terms in the liquid crystal free energy density upon integration of the polymer fields. First,

depends on what kind of fluctuations are present in the smectic A phase : layer undulations or molecular tilt. They could of course, in general, occur

Presumably the acoustical attenuation arises from coupling of sound waves with both fluctuations of the director and magnitude of the order parameter. Unfortunately it is

Precise measurements of the Kerr effect [6, 9] and magnetic birefringence [6, 7] in the isotropic phase of. some nematic substances have been

We have reported in table I1 the value of the mean area per chain A for each value of a .For four chains phasmids we choose the smallest value of a since it corresponds to
