TLDR
In this article, the authors have observed a divergence of the magnetic birefringence, and a critical increase and slowing of the fluctuations in order in the isotropic phase of a nematic liquid crystal.Abstract:
We have observed a divergence of the magnetic birefringence, and a critical increase and slowing of the fluctuations in order in the isotropic phase of a nematic liquid crystal. Our results are quantitatively described by a mean-field model except for a critical region close to the ordering temperature where the fluctuations are so large that the meanfield approximation fails.read more

Continuity of flow alignment parameters across the nematic-isotropic phase transition
TL;DR: In this paper, the authors used existing data to show that the parameter which characterizes the reactive coupling of molecular orientation to shear strain in the nematic liquid crystal N-(p'-methoxybenzylidene)-p-n-butylaniline (MBBA) is continuous across the phase transition.

The Phase Transition Behavior of Mixtures of Nematic Liquid Crystal with Non-Mesogenic Solute Molecules
TL;DR: In this paper, the magnetic birefringence and the refractive indices have been measured for the following binary solution systems: (1) Tetrabutyl-tin MBBA, (2) Cyclohexene MBBA.

Emergence of a linear slope region of the isotherm in the first-order liquid-expanded-liquid-condensed phase transition in Langmuir monolayers

TL;DR: It is found from the comparison of the two-dimensional contour plots of the free energy that an LE phase may persist significantly even at the later stage of the straight-line regime beyond a transition midpoint surface pressure in the presence of this coupling.
