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…
Hierarchy of Periodic patterns in the twist-bend nematic phase of mesogenic dimers
Vitaly P. Panov, Michael C. M. Varney, Ivan I. Smalyukh +3
Several attractive properties of hydrocarbon-linked mesogenic dimers have been discovered, a major feature of these has been the ability of dimers under confinement to form periodi…
Nematic twist-bend phase with nanoscale modulation of molecular orientation
Volodymyr Borshch, Young-Ki Kim, Jie Xiang +8
A state of matter in which molecules show a long-range orientational order and no positional order is called a nematic liquid crystal. The best known and most widely used (for exam…
