The Freedericksz Transition in a Spatially Varying Magnetic Field

open access: yesCrystals, 2021
Much is known about the Freedericksz transition induced by uniform electric and magnetic fields in nematic liquid crystals. In this work, we are interested in the effects of a spatially varying field on the transition. Specifically, we study the director

Symmetry and Liquid Crystals

open access: yesSymmetry, 2023
Liquid crystals are aggregates of individual molecules due to moderate intermolecular interactions, which are roughly divided into lyotropic liquid crystals and thermotropic liquid crystals [...]

Designs of Plasmonic Metamasks for Photopatterning Molecular Orientations in Liquid Crystals

open access: yesCrystals, 2016
Aligning liquid crystal (LC) molecules into spatially non-uniform orientation patterns is central to the functionalities of many emerging LC devices. Recently, we developed a new projection photopatterning technique by using plasmonic metamasks (PMMs ...

Ferroelectric liquid crystals [PDF]

open access: yesJournal 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.

Liquid crystal elastomer coatings with programmed response of surface profile

open access: yesNature Communications, 2018
Liquid crystal elastomers are anisotropic rubbers which can be actuated by an external trigger. Here the authors develop elastomer coatings with pre-patterned molecular orientation that induces deterministic topography changes in response to changes in ...

Author Correction: Liquid crystal elastomer coatings with programmed response of surface profile

open access: yesNature Communications, 2018
The original version of this Article contained errors in Figs. 1a, 2a, 3a, and 4b, in which the units on the scale bars incorrectly read ‘µm’ rather than the correct ‘nm.’ This has been corrected in both the PDF and HTML versions of the Article.

ZnO1−xSx Nanosphere in Ferroelectric Liquid Crystal Matrix: The Effect of Aggregation and Defects on the Dielectric and Electro-Optical Properties

open access: yesAdvances in Condensed Matter Physics, 2013
High concentration (5 wt %) of ZnO1−xSx nanosphere (NS) has been dispersed in the ferroelectric liquid crystal (FLC) to analyze the effect of high dopant concentration in the FLC matrix. The FLC molecules actively interact with the NS. The presence of NS

Liquid Crystals as Organogelators: Liquid Crystals Gelled Organic Liquids

open access: yesJournal of Oleo Science, 2006
Gelation tests of rod like liquid crystals (LCs), columnar LCs, and cholesteric LCs rod-like have been employed. 4-Cyanophenyl 4-n-alkoxybenzoates, 4-cyano-4’-alkoxybiphenyls, 4,4’-dialkanoyloxybiphenyls, azoxybenzene derivatives, 2,3,6,7,10,11-hexaalkoxytriphenylenes, and cholesteryl esters, except for cholesteryl alkyl carbonates and cholesteryl ...

Liquid Crystals in Tribology [PDF]

open access: yesInternational Journal of Molecular Sciences, 2009
Two decades ago, the literature dealing with the possible applications of low molar mass liquid crystals, also called monomer liquid crystals (MLCs), only included about 50 references. Today, thousands of papers, conference reports, books or book chapters and patents refer to the study and applications of MLCs as lubricants and lubricant additives and ...
