Critical exponents and universality for the isotropic-nematic phase transition in a system of self-assembled rigid rods on a lattice
(American Physical Society, 2009-10)
Monte Carlo simulations have been carried out for a system of monomers on square lattices that, by decreasing temperature or increasing density, polymerize reversibly into chains with two allowed directions and, at the ...
Isotropic-nematic phase diagram for interacting rigid rods on two-dimensional lattices
(American Physical Society, 2012-01-20)
The phase behavior of interacting rigid rods of length k (k-mers) on two-dimensional square and triangular lattices has been studied by theoretical calculations in the framework of the lattice-gas model. The process was ...
Discotic Nematic - Calamitic Nematic Phase Transition in Sodium Dodecyl (lauryl) Sulphate-Decanol-D2O
(TAYLOR & FRANCIS LTD, 2011)
The optical characterization of uniaxial nematic liquid crystals gives basic information on its birefringence and on the shape anisotropy of micelles in nematic lyotropic phases. In this work, these optical parameters were ...
The Liquid Crystal State of Matter
(Seminário de Iniciação Científica e Tecnológica da UTFPR, 2017)
Generalized van der Waals theory for phase behavior of two-dimensional nematic liquid crystals: Phase ordering and the equation of state
(American Physical Society, 2019-12)
Liquid crystalline ordering of anisotropic particles in two dimensions is important in many physical and biological systems and their phase behavior is still a topic of interest. A generalized van der Waals theory is ...
Enhancement of the Nonlinear Optical Absorption of the E7 Liquid Crystal at the Nematic-Isotropic Transition
(SPRINGERNEW YORK, 2012)
We present an experimental study of the nonlinear optical absorption of the eutectic mixture E7 at the nematic-isotropic phase transition by the Z-scan technique, under continuous-wave excitation at 532 nm. In the nematic ...
Non-isothermal model for nematic spherulite growth
(American Chemical Society, 2008-12)
A computational study of the growth of two-dimensional nematic spherulites in an isotropic phase was performed using a Landau-de Gennes-type quadrupolar tensor order parameter model for the first-order isotropic/nematic ...
Temperature dependence of the refractive index near the reentrant-isotropic-calamitic-nematic phase transition
(American Physical SocCollege PkEUA, 2001)
Tricritical-like behavior of the nonlinear optical refraction at the nematic-isotropic transition in the E7 thermotropic liquid crystal
(SPRINGERNEW YORK, 2012)
We use Z-scan technique to investigate the nonlinear optical response of the thermotropic liquid crystal E7 in the neighborhood of the nematic-isotropic phase transition. The analysis of the data for the nonlinear optical ...
