Function spaces for liquid crystals [PDF]

open access: yes, 2014
We consider the relationship between three continuum liquid crystal theories: Oseen-Frank, Ericksen and Landau-de Gennes. It is known that the function space is an important part of the mathematical model and by considering various function space choices

Transmissive Multilayer Geometric Phase Gratings Using Water-Soluble Alignment Material

open access: yesCrystals
Multilayer liquid crystal devices can offer enhanced optical functionalities for augmented reality and photonic applications, but fabrication remains severely limited by solvent incompatibility between photoalignment materials and underlying polymerized ...

Chirality amplification by desymmetrization of chiral ligand-capped nanoparticles to nanorods quantified in soft condensed matter

open access: yesNature Communications, 2018
The mechanisms by which molecular chirality is amplified through space and across length scales is of great interest. Here the authors show how gold nanorods covered in chiral dopants are more efficient in transducing chiral information compared to other

Pixelated Photonic Crystals

open access: yesAdvanced Photonics Research, 2023
Photonic crystals can prevent or allow light of certain frequencies to propagate in distinct directions in anomalous and useful ways for use as waveguides, laser cavities, and topological light propagation.

Phase Behavior and Ionic Conductivity of Blended, Ion-Condensed Electrolytes with Ordered Morphologies

open access: yesApplied Sciences, 2022
In this study, the amphiphilic salt lithium trifluoromethanesulfonylimide octadecane (C18LiTFSI) was used as a basis to investigate the effects of anion density and cation coordination sites within blended electrolytes with strong ionic aggregation ...

Nematic liquid crystal devices with sub-millisecond response time [PDF]

open access: yes, 2014
Conventional nematic liquid crystal devices exhibit switching times that are in the order of several milliseconds. In this work we focus on two types of nematic liquid crystals that can overcome the limitations of conventional nematic liquid crystals and

Order and Frustration in Chiral Liquid Crystals [PDF]

open access: yes, 2000
This paper reviews the complex ordered structures induced by chirality in liquid crystals. In general, chirality favors a twist in the orientation of liquid-crystal molecules. In some cases, as in the cholesteric phase, this favored twist can be achieved
