Soliton walls paired by polar surface interactions in a ferroelectric nematic liquid crystal
Nature Communications, 2022 Surface interactions are usually polar along the normal to the interface and apolar within the interface. Here, the authors find that polar in-plane surface interactions produce domain structures in the bulk of a ferroelectric nematic liquid crystal.

Biophysical Journal, 2014 SignificanceWe propose a class of active matter, the living liquid crystal (LLC), representing motile rod-shaped bacteria placed in water-based nontoxic liquid crystal. Long-range orientational order of the liquid crystal and the swimming activity of bacteria demonstrate a strong coupling that dramatically alters individual and collective bacterial ...

Liquid crystal-based structural color actuators
Light: Science & Applications, 2022 Animals can modify their body shape and/or color for protection, camouflage and communication. This adaptability has inspired fabrication of actuators with structural color changes to endow soft robots with additional functionalities.

Azimuthal Anchoring Strength in Photopatterned Alignment of a Nematic
Crystals, 2021 Spatially-varying director fields have become an important part of research and development in liquid crystals. Characterization of the anchoring strength associated with a spatially-varying director is difficult, since the methods developed for a ...

Ferroelectric nematic liquids with conics
Nature Communications, 2023 Defect lines shaped as conic sections are common in smectic liquid crystals, where they manifest equidistance of molecular layers curled in space. Here authors present hyperbolas and parabolas as domain walls in ferroelectric nematics, which are shaped ...

Ferroelectric liquid crystals [PDF]
Journal de Physique Lettres, 1975 A general symmetry argument is presented, and experiments on newly synthesized p-decyloxybenzylidene p'-amino 2-methyl butyl cinnamate are described, demonstrating that chiral smectic C and H liquid crystals are ferroelectric. Some of the properties of this new class of ferro-electrics are discussed.

Monolithic shape-programmable dielectric liquid crystal elastomer actuators [PDF]
Science Advances, 2019 Maxwell stress–activated shape-morphing liquid crystal elastomer actuators are efficient, fast, and forceful. Soft robotics may enable many new technologies in which humans and robots physically interact, yet the necessary high-performance soft actuators
