The molecular theory of Onsager [L. Onsager, Ann. N.Y. Acad. Sci. 51, 627 (1949)] for liquid crystals is developed and extended to describe ordering transitions in systems of generic cylindrically symmetrical molecules. A number of new analytical results are discussed for particles characterised by a general form of the excluded-volume interaction. Our description makes use of the Onsager trial function (OTF) to represent the orientational distribution and degree of anisotropy. Algebraic… 
An Equation of State for the Isotropic-Nematic Phase Transition of Semiflexible Polymers
Based on the thermodynamic perturbation theory for polymer, a new equation is proposed by incorporating a wide range of molecular flexibility and perturbative interactions to describe the
The isotropic-nematic phase transition of tangent hard-sphere chain fluids--pure components.
An extension of Onsager's second virial theory is developed to describe the isotropic-nematic phase transition of tangent hard-sphere chain fluids and allows for an analytical treatment of intramolecular flexibility by using a single pure-component parameter.
Liquid Crystal Phase Behaviour of Attractive Disc-Like Particles
A generalized van der Waals-Onsager perturbation theory is employed to construct a free energy functional capable of describing the thermodynamic properties and orientational order of the isotropic and nematic phases of attractive disc particles and shows that the addition of an attractive interaction facilitates the formation of orientationally-ordered phases.
Isotropic-Nematic Transition and Demixing Behavior in Binary Mixtures of Hard Spheres and Hard Spherocylinders Confined in a Disordered Porous Medium: Scaled Particle Theory.
The scaled particle theory is developed to describe the thermodynamic properties and orientation ordering of a binary mixture of hard spheres (HS) and hard spherocylinders (HSC) confined in a disordered porous medium and correctly predicts the isotropic-nematic transition at low concentrations ofhard spheres.
Development of an equation of state for nematic liquid crystals
In this thesis I aim to contribute to a molecular understanding and -description of the phase behaviour of liquid crystalline materials. In particular, I aim at the development of a molecular-based
A Simple Free Energy for the Isotropic-Nematic Phase Transition of Rods
A free energy expression is proposed that describes the isotropic-nematic binodal concentrations of hard rods. A simple analytical form for this free energy was yet only available using a Gaussian
Molecular Simulation of Liquid Crystals: Phase Equilibrium and the Solubility of Gases in Ordered Fluids
Monte Carlo simulations were performed in the NPT ensemble and in an expanded version of the Gibbs ensemble. The phase behavior of single-phase hard-sphere chain fluids was determined using NPT
Structure and Interfacial Tension of a Hard-Rod Fluid in Planar Confinement.
Accurate values of the fluid-solid surface tension, the adsorption, and the average particle-wall contact distance are reported (over a broad range of densities into the dense nematic region for the first time), which can serve as a useful benchmark for future theoretical and experimental studies on confined rod fluids.
Polymeric Nematics of Associating Rods: Phase Behavior, Chiral Propagation, and Elasticity
Rod-shaped colloids with attractive tips can form linear aggregates that may subsequently undergo hierarchical self-assembly into nematic fluids. Inspired by recent modeling efforts on chromonic
Nanorings in planar confinement: the role of repulsive surfaces on the formation of lacuna smectics
ABSTRACT We study the structure and liquid-crystalline phase behaviour of a model of confined non-convex circular soft-repulsive nanorings in a planar slit geometry using molecular-dynamics


Liquid Crystals
The subject is not easily understood, and most of the experiments upon which it is founded cannot be performed without special apparatus, so it has so far received scanty attention in this country, and its extreme importance is perhaps not fully realised.
It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
Equations of State for Fluids and Fluid Mixtures
Fluids1) abound during the formation of most rocks and mineral deposits. In the majority of geological environments, they tend to be mixtures of a number of species like H2O, CO2, CH4, CO, H2, N2,
