TL;DR: The scalar order parameter of the phase of Blue 27 is determined to be relatively high, in the range 0.72-0.79, which puts the finding into the domain of general validity of the Onsager model, however, the observed temperature dependence of the scalar Order parameter points to the importance of factors not accounted for in the athermal Onsagersager model.

TL;DR: The director distortions in the nematic liquid crystal (LC) caused by a spherical particle with tangential surface orientation of the director are described and it is shown that light transmittance through the distorted region is a steep function of the particle's size.

TL;DR: In this article, a real-time microbial sensor based on a lyotropic chromonic liquid crystal (LCLC) was proposed to detect and amplify the presence of immune complexes.

TL;DR: In this paper, the authors describe polarizing films formed from the lyotropic liquid crystalline phases of dyes dissolved in water, which are suitable for twisted nematic devices based on low cost birefringent plastic substrates.

TL;DR: Atomic force microscopy and X-ray photoelectron spectroscopy of the dried film reveal that the LCLC molecules adsorb at the charged substrate preserving ordered aggregates of elongated shape characteristic of the nematic phase in the aqueous solution.
