The Three Coefficients of Viscosity of Anisotropic Liquids
TL;DR: Having given the molecules an orientation by means of a magnetic field in such circumstances that the flow did not change this orientation, the following values are obtained for the three principal viscosity coefficients for p-azoxyanisol and p-AZoxyphenetol.

The shear viscosity minimum of freely flowing nematic liquid crystals
Jan Jadżyn,Grzegorz Czechowski +1 more
TL;DR: In this paper, the analysis of temperature dependence of the shear viscosity of freely flowing nematic liquid crystals was performed and it was shown that the anisotropic fluid adopts such a manner of flow, which corresponds to the minimum of its viscosities at given conditions.

Static and dynamic dielectric behavior of mesogenic compounds of different polarity in the vicinity of the isotropic to nematic phase transition.
TL;DR: Mesogenic compounds belonging to the two well-known -cyanophenyl, and -isothiocyanatophenyl homologous series, show an essential difference in the pretransitional dielectric behavior in the vicinity of the isotropic to nematic (I-N) phase transition.
