Application of a generalised thermodynamic model to study of the ferroelectric properties of DOBAMBC and DOBA‐1‐MPC
Abhilasha Singh,Shri Singh +1 more
TL;DR: In this paper, the temperature variations of tilt angle, spontaneous polarisation, helical pitch, Goldstone mode rotational viscosity and twist elastic constant of the ferroelectric smectic C (SmC*) phase near the SmA-SmC* transition of the Ferroic mesogens DOBAMBC and DOBA•1•MPC were calculated using a thermodynamic model based on an extended Landau expansion of the free energy density.
Journal ArticleDOI
Perturbation Theory for Nematic Liquid Crystals of Axially Symmetric Molecules: Extension of Calculations to High Pressures
K. Singh,Shri Singh +1 more
TL;DR: In this paper, a statistical mechanical perturbation theory was applied to study the thermodynamic properties of nematic liquid crystals under pressure, where the reference potential function is nonspherical and consists of the short range rapidly varying repulsive part of the pair potential.
Journal ArticleDOI
Investigation of dielectric and optical properties of pure and diamond nanoparticles dispersed nematic liquid-crystal PCH5
Dhananjay Kumar Gaur,Ayushi Rastogi,Harshita Trivedi,Avanish S. Parmar,Rajiv Manohar,Shri Singh +5 more
TL;DR: In this article, the authors have dispersed diamond nanoparticles (DNPs) in nematic liquid crystal 4-(Trans-4ʹ-n-Pentylcyclohexyl) Benzonitrile (PCH5) and studied the dielectric and optical properties.
Journal ArticleDOI
Perturbation Theory for Nematic Liquid Crystals of Axially Symmetric Molecules: II. Effect of Quadrupolar Forces
Shri Singh,K. Singh +1 more
TL;DR: In this article, a statistical perturbation theory derived from the work of Singh and Singh was applied to analyze the influence of quadrupole interaction on a variety of thermodynamic properties of nematic liquid crystals.
Journal ArticleDOI
Studies of dispersed liquid crystals in binary mixtures with ionic liquid and their excitation by electric signals
TL;DR: In this paper, the authors report the results of dispersion studies of two nematogens (i) 6CHBT (4-(trans-4-nhexylcyclohexyl)isothiocyanatobenzene) and (ii) PCH5) in their binary mixtures with a phosphonium-based ionic liquid [P6,6, 6,14] (trihexyl(tetradecyl)phosphoniumbis(trifluoromethylsulfonyl)amide).
