We report measurements of the temperature variations of physical parameters in ambient-temperature nematic liquid crystal mixtures of bent-core (BC) and rodlike molecules (5CB): birefringence Δn; static dielectric constants ε(||) and ε(⊥); splay K(11) and bend K(33) elastic constants; rotational viscosity γ(1); and diffusion coefficients D(||) and D(⊥) of a microsphere. Both Δn and ε(||) decreases rapidly with increasing BC concentration, whereas ε(⊥) remains almost constant. At a shifted… Expand

TLDR
Calculated elastic constants via molecular-field theory and atomistic modeling are in excellent qualitative as well as good quantitative agreement with the measurements across the temperature range, offering a deeper understanding of the elasticity in bent-core nematic materials than has been, hitherto, available.

Binary System Exhibiting the Nematic to Twist-Bend Nematic Transition: Behavior of Permittivity and Elastic Constants.
TLDR
Measurements of the permittivity and Frank elastic constant in the nematic phase of a binary system displaying a transition between the nematics (N) and the recently discovered twist-bend nematic (NTB) phase support the surprising idea that the elastic features associated with bent molecules can be further augmented by suitable rodlike additives.
