Molecular organization in the twist-bend nematic phase by resonant X-ray scattering at the Se K-edge and by SAXS, WAXS and GIXRD
W. D. Stevenson, Z. Ahmed, X. B. Zeng +3
Using a novel Se-labelled dimer mixed with DTC5C7 aligned by magnetic field, the twist-bend nematic phase (Ntb) in dimers was studied by hard X-ray resonant scattering and by small…
Comparative analysis of anisotropic material properties of uniaxial nematics formed by flexible dimers and rod-like monomers
Greta Cukrov, Youssef Mosaddeghian Golestani, Jie Xiang +5
We report temperature dependencies of material properties such as dielectric anisotropy, birefringence, splay (K11), twist (K22), and bend (K33) elastic constants of the uniaxial n…
Light scattering study of the "pseudo-layer" compression elastic constant in a twist-bend nematic liquid crystal
Z. Parsouzi, Shokir A. Pardaev, C. Welch +9
The nematic twist-bend (TB) phase, exhibited by certain achiral thermotropic liquid crystalline (LC) dimers, features a nanometer-scale, heliconical rotation of the average molecul…
Second harmonic light scattering induced by defects in the twist-bend nematic phase of liquid crystal dimers
Shokir A. Pardaev, S. M. Shamid, M. G. Tamba +8
The nematic twist-bend () phase, exhibited by certain thermotropic liquid crystalline (LC) dimers, represents a new orientationally ordered mesophase -- the first…
Anomalous increase in nematic-isotropic transition temperature in dimer molecules induced by magnetic field
S. M. Salili, M. G. Tamba, S. N. Sprunt +4
We have determined the nematic-isotropic transition temperature as a function of applied magnetic field in three different thermotropic liquid crystalline dimers. These molecules a…
