TL;DR: A photon transmission technique was used to monitor the multiple phase transitions in a 4-butoxyphenyl4(')-declyoxybenzoate (BOPDOB) liquid crystal and it was found that the order parameter rho is proportional to the transmitted photon intensity.

TL;DR: It has been found that the area A of the hysteresis loops scales with the temperature scanning rate R as A=A(0)+bR(n) with the exponent n equal to 0.692, which is consistent with the (Phi(2))(3) field theoretical model value within the experimental resolution.

TL;DR: In this paper, a bipartitional polytetrahydrofuran (PTHF)-PMMA macromonomer was synthesized by the termination of living polymerization of tetrahydric acid (THF) initiated by triflic anhydride and subsequent termination by sodium methacrylate.

TL;DR: In this article, high-resolution optical birefringence measurements are reported on the weakly first order nematicisotropic (N-I) and the continuous nematic-smectic A (N -Sm A) phase transitions in smectic liquid crystal 8CB (octylcyanobiphenyl) doped with both pristine multi-walled carbon nanotubes (p-MWCNTs) and carboxyl group functionalized MWCNTs (f-MW CNTs).

TL;DR: In this paper, ultraviolet/visible photon transmission measurements were applied to study liquid crystal phase transitions in the binary BOPDOB-BOPOOB mixture, and a sequence exhibiting a new reentrant, namely isotropic-nematic-smectic A-C-A as temperature is lowered, was identified.
