Accurate quantitative structure–property relationship analysis for prediction of nematic transition temperatures in thermotropic liquid crystals
TL;DR: In this paper, a quantitative structure-property relationship approach was performed to study the nematic transition temperatures (T N) in thermotropic liquid crystals, and the multi-linear regression analysis (MLRA) and artificial neural networks (ANNs) were employed to develop linear and nonlinear models, respectively.
Journal ArticleDOI
Smectic phase in a system of hard ellipsoids with isotropic attractive interactions.
TL;DR: In this article, the smectic phase of a thermotropic fluid model consisting of aligned hard ellipsoids with superimposed square-well attractive interactions of variable range is studied.

Liquid crystalline behavior of a coarse-grained model of shape-persistent macrocycles with flexible attractive chains
Carlos Avendaño,Erich A. Müller +1 more
TL;DR: Avendano et al. as discussed by the authors studied the effect of flexible chains attached to the shape-persistent macrocycles (SPMs) on the self-assembly of SPMs and found that the attached chains are either pointing inward or outward from the rigid structure.

Interactions and dynamics of mesogenic molecules in the vicinity of the isotropic to nematic phase transition
Jan Jadżyn,Grzegorz Czechowski +1 more
TL;DR: A role of the molecular structure and polarity in the dielectric behavior of nematogenic compounds in the vicinity of the isotropic to nematic phase transition is discussed in this article.

Magnetic-field-induced changes of the isotropic-nematic phase transition in side-chain polymer liquid crystals
TL;DR: The isotropic-nematic (I-N) phase transition of side-chain polymer liquid crystals is intrinsically a weak first-order transition with a biphasic region spread over a wide temperature interval, but in the presence of high magnetic fields the I-N transition to become a strong first order.

Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.

Density-functional theory of atoms and molecules
TL;DR: In this paper, a review of current studies in density functional theory and density matrix functional theory is presented, with special attention to the possible applications within chemistry, including the concept of an atom in a molecule, calculation of electronegativities from the Xα method, pressure, Gibbs-Duhem equation, Maxwell relations and stability conditions.
