TL;DR: In this article, it was found that doping a nematic liquid crystal with a small amount of ferroelectric nanoparticles strongly affects the dielectric properties of the system, and that adding the particles results in a shift of the absorption bands corresponding to the rotation of liquid crystal molecules around their short axes to lower frequencies and in an increase of the amplitude and with of absorption bands, suggesting that strong interactions occur between the LC molecules and the particles, caused by the large dipole moment and high polarizability of the ferro-particles.

TL;DR: Photorefractive diffraction gratings were studied in cells of homeotropically aligned pentyl-cyanobiphenyl liquid crystal and induced by the simultaneous and nonsimultaneous application of dc and coherent optical electric fields, consistent with a predominantly surface-mediated photorefraction effect.

TL;DR: In this article, the authors summarize their many years of experience in the preparation and optimization of stable colloids of ferroelectric nanoparticles dispersed in an isotropic carrier and in a liquid crystal host.

TL;DR: In this article, the effect of reversible shift of selective reflectivity band in induced cholesteric LC under the laser irradaition was investigated and the effect was shown to be reversible.
