TL;DR: In this article, the authors developed a dilute suspension of ferroelectric particles in a nematic liquid-crystal (LC) host, and found that the submicron particles do not disturb the LC alignment and the suspension macroscopically appears similar to a pure LC with no readily apparent evidence of dissolved particles.

TL;DR: The physical properties of low concentration ferroelectric nematic colloids are investigated using calorimetry, optical methods, infrared spectroscopy, and capacitance studies, and a theoretical model is proposed in which the ferroElectric particles induce local dipoles whose effective interaction is proportional to the square of the orientational order parameter.

TL;DR: In this article, the fundamental optics of lenses and its extension to lenses made of liquid crystals (LCs) are described, namely, lenses with curved surfaces, flat gradient-index lenses and composite lenses.

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: An oriented photopolymer is a polymer where photomodification is initiated by irradiation with plane-polarized light and where the molecular configuration has a preferred orientation as a result of linear polarization.
