Entropy stabilized form chirality in curved rod nematics: structure and symmetries
Alexandros G. Vanakaras, Edward T. Samulski, Demetri J. Photinos
Monte Carlo molecular simulations of curve-shaped rods show the propensity of such shapes to polymorphism revealing both smectic and polar nematic phases. The nematic exhibits a na…
Dipole-dipole correlations in the nematic phases of symmetric cyanobiphenyl dimers and their binary mixtures with 5CB
Evangelia E. Zavvou, Efthymia Ramou, Ziauddin Ahmed +4
We report on the temperature dependence of birefringence and of the static dielectric permittivity tensor in a series of binary mixtures between the symmetric, bent-shaped, 1",9"-b…
Light scattering by a metallic nanoparticle coated with a nematic liquid crystal
Vassilios Yannopapas, Nikolaos G. Fytas, Vicky Kyrimi +3
We study the optical properties of gold nanoparticles coated with a nematic liquid crystal whose director field is distributed around the nanoparticle according to the anchoring co…
'Setting things straight' by twisting and bending?
Edward T. Samulski, Alexandros G. Vanakaras, Demetri J. Photinos
We explain the origins of the controversy about the classification of the phase observed in cyanobiphenyl dimers and why it is a polar twisted phase, an entirely new kind of…
The Twist Bend Nematic: A Case of Mistaken Identity
Edward T. Samulski, Alexandros G. Vanakaras, Demetri J. Photinos
We review the physics underlying Meyer's conjecture of how macroscopic-scale twist and bend conspire within the Frank-Oseen elasticity theory of nematics to create a heliconical ar…
Probing Molecular Ordering in the Nematic Phases of para-Linked Bimesogen Dimers through NMR Studies of Flexible Prochiral Solutes
Leah M. Heist, Edward T. Samulski, Chris Welch +4
The quadrupolar splittings of perdeuteriated n-decane dissolved in nematic phases formed by mesogenic dimers of the CBnCB series, for n=7,9,10,11 are measured throughout the entire…
