The Nematic Phase of a System of Long Hard Rods
TL;DR: In this paper, a two-dimensional lattice model for liquid crystals consisting of long rods interacting via purely hard core interactions, with two allowed orientations defined by the underlying lattice, is considered.

Higher Order Liquid Crystalline Structure in Low-Polydispersity DEH-PPV
TL;DR: In this paper, a monodisperse, low molecular weight poly(2,5-di (2,2,ethylhexyloxy)-1,4-phenylenevinylene) (DEH-PPV) demonstrates significantly better structural order than polydisperse PPVs.

Flávia Chiva Carvalho,Victor Hugo Vitorino Sarmento,Leila Aparecida Chiavacci,Mariana da Silva Barbi,Maria Palmira Daflon Gremião +4 more
TL;DR: Systems composed of polyoxypropylene (5) polyoxyethylene (20) cetyl alcohol as surfactant (S), oleic acid as oil phase (O), and water (W) were developed, as possible AZT control release systems, indicating that AZT could be released in a controlled manner.

The phase behavior, structure, and dynamics of rodlike mesogens with various flexibility using dissipative particle dynamics simulation
Zunmin Zhang,Hongxia Guo +1 more
TL;DR: In this study, the rigid and semirigid models used are valuable models with which to study the behavior of thermotropic liquid crystals using DPD algorithm and the anisotropic translational diffusion in liquid crystal phases and its temperature and flexibility dependence is investigated.

Thermodynamic scaling and the characteristic relaxation time at the phase transition of liquid crystals.
C. M. Roland,R. B. Bogoslovov,Riccardo Casalini,A. R. Ellis,Scott Bair,Sylwester J. Rzoska,Krzysztof Czupryński,Stanisław Urban +7 more
TL;DR: There is a surprising relationship between the thermodynamic conditions defining the stability limits of a liquid crystalline phase and the dynamic properties reflected in the magnitude of the longitudinal relaxation time.

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.
