Lipid Hydrocarbon Tail Structure Governs Interfacial Anchoring and Stripe Morphology in Cholesteric Liquid Crystals
Mengwei Li, Stefanie D. Pritzl, Martin F. Haase +1
Liquid crystal-based biosensors exploit the sensitivity of interfacial anchoring to molecular adsorption. Cholesteric liquid crystals are especially useful because their helical st…
Lipid-Mediated Control of Thermally Induced Shape Transformations in Liquid Crystal Droplets
Mengwei Li, Lisa Tran
Lipids and liquid crystals provide a useful platform for addressing how molecular-scale organization is translated into mesoscale shape transformation. Variations in hydrocarbon-ch…
Helfrich-Hurault elastic instabilities driven by geometrical frustration
Christophe Blanc, Guillaume Durey, Randall D. Kamien +3
The Helfrich-Hurault (HH) elastic instability is a well-known mechanism behind patterns that form as a result of strain upon liquid crystal systems with periodic ground states. In…
Undulation instabilities in cholesteric liquid crystals induced by anchoring transitions
Maxim O. Lavrentovich, Lisa Tran
Cholesteric liquid crystals (CLCs) have a characteristic length scale given by the pitch of the twisted stacking of their constituent rod-like molecules. Under homeotropic anchorin…
Swelling cholesteric liquid crystal shells to direct colloids at the interface
Lisa Tran, Kyle J. M. Bishop
Cholesteric liquid crystals can exhibit spatial patterns in molecular alignment at interfaces that can be exploited for particle assembly. These patterns emerge from the competitio…
Shaping nanoparticle fingerprints at the interface of cholesteric droplets
Lisa Tran, Hye-Na Kim, Ningwei Li +4
The ordering of nanoparticles into predetermined configurations is of importance to the design of advanced technologies. In this work, we moderate the surface anchoring against the…
A change in stripes for cholesteric shells via anchoring in moderation
Lisa Tran, Maxim O. Lavrentovich, Guillaume Durey +7
Chirality, ubiquitous in complex biological systems, can be controlled and quantified in synthetic materials such as cholesteric liquid crystal (CLC) systems. In this work, we stud…
Lassoing saddle splay and the geometrical control of topological defects
Lisa Tran, Maxim O. Lavrentovich, Daniel A. Beller +3
Systems with holes, such as colloidal handlebodies and toroidal droplets, have been studied in the nematic liquid crystal (NLC) 4-cyano-4'-pentylbiphenyl (5CB): both point and ring…
