In the Onsager theory for the phase transition from the isotropic fluid to the nematic liquid
crystal phase, the Helmholtz free energy of a fluid of hard convex bodies (HCBs) is …

The phase transition from an isotropic to a nematic phase for a classical fluid of hard
ellipsoids has been studied using a version of a theory originally due to Onsager and by …

We extend the generalized van der Waals (GVDW) theory to fluids of anisotropic molecules
interacting through angle‐dependent potentials which can be broken up into strong short …

Dense fluids of biaxial hard convex bodies exhibit a phase transition from an isotropic to a
nematic (I–N) liquid–crystalline state. In the Onsager theory, the I–N transition is attributed to …

The isotropic–nematic phase transition in a fluid of moderately long molecules interacting
via a hard Gaussian overlap potential is studied using the decoupling approximation and …

The effects of solute molecular structure (size, shape and flexibility) and solvent molecular
structure (length‐to‐breadth ratio and end‐chain flexibility) on nematic phase stability in …

The molecular theory of Onsager [L. Onsager, Ann. NY Acad. Sci. 51, 627 (1949)] for liquid
crystals is developed and extended to describe ordering transitions in systems of generic …

The parameters characterizing the isotropic–nematic phase transition in liquid crystals have
been calculated using a generalized van der Waals theory. The molecules are assumed to …

Using an iterative solution to the Onsager integral equation for the orientational distribution
function of spherocylinders in the nematic liquid crystal phase, we have studied several …

When nonmesomorphic solutes are added to nematic liquid crystals, the nematic-isotropic
transition temperature is depressed and a two-phase region is observed. The slopes, 13M …
