Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions. [PDF]
Abstract Liquid crystal elastomers (LCEs) are promising building blocks for soft robots, given their large, programmable, reversible, and stimuli‐responsive shape change. Enhancing LCEs’ stiffness and toughness has been a longstanding desire previously explored by reinforcing them with fillers, crystalline microdomains, and ...

Soliton walls paired by polar surface interactions in a ferroelectric nematic liquid crystal
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.

Ferroelectric nematic liquids with conics
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 ...

Azimuthal Anchoring Strength in Photopatterned Alignment of a Nematic
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 ...

Self-Localized Liquid Crystal Micro-Droplet Arrays on Chemically Patterned Surfaces
Liquid crystal (LC) micro-droplet arrays are elegant systems that have a range of applications, such as chemical and biological sensing, due to a sensitivity to changes in surface properties and strong optical activity.

Artificial web of disclination lines in nematic liquid crystals
Disclination lines are topological defects in molecular orientation widely found in liquid crystals. Here Wang et al. use a surface patterning technique to produce a very stable freestanding 3D array of ½ twist disclinations, which could be exploited in ...

Three-dimensional solitary waves with electrically tunable direction of propagation in nematics
In a previous work, the authors have demonstrated the formation of localized waves in nematic liquid crystals driven by an electric field. Here they demonstrate the realization of solitary waves of (3+2)D type which can be steered along longitudinal and ...

Gram-to-Kilogram Scale-Up Synthesis of 2,2’-Diallylbisphenol through a Microchannel Reactor [PDF]
A continuous-flow synthetic platform utilizing a microchannel reactor was developed here to realize the gram-to-kilogram scale-up synthesis of 2,2’-diallylbisphenol A (DABPA) via thermal Claisen rearrangement with high efficiency and safety.
