Enhancement of Microorganism Swimming Speed in Active Matter.
TL;DR: Using numerical methods to probe this regime of an active nematic liquid crystal, it is found that activity enhances the swimming speed by an order of magnitude compared to the passive case.

TL;DR: The authors have measured the electro-optic Kerr effect in the isotropic phase of a urea derivative and found that optical second-harmonic generation (SHG) is easily observable in the low-temperature region on applying an electric field, whereas SHG activity does not emerge in the higher-tem temperature region.

Nematic-isotropic phase transition in lyotropic liquid crystals
TL;DR: In this paper, a Landau-de Gennes phenomenological model is proposed to describe the nematic-isotropic phase transition in lyotropic liquid crystals, and the possibility of a first or second order transition is explored by means of the variation of the concentration of surfactant.

Nuclear relaxation in a nematic liquid crystal
TL;DR: In this paper, the authors estimate the contributions to T1 and T2 in a nematic liquid crystal arising from the fluctuations in the orientational order, which results in relaxation times of the order of one second which is typical of ordinary liquids.
