Towards in silico liquid crystals. Realistic transition temperatures and physical properties for n-cyanobiphenyls via molecular dynamics simulations.
TL;DR: By using the united-atom force field developed herein, it is shown that the experimental isotropic-nematic transition temperatures are reproduced within 4 K, allowing a molecular-level interpretation of the odd-even effect along the series.

Structure And Thermodynamics of Weakly Segregated Rod-Coil Block Copolymers
TL;DR: In this paper, the selfassembly of a series of monodisperse rod−coil block copolymers is studied in the weak segregation limit, and the order to microphase disorder transition (ODT) and nematic isotropic (NI) transition are experimentally investigated.

Mechanochromic luminescence of halide-substituted difluoroboron β-diketonate dyes
TL;DR: In this paper, the effects of halide substituents on mechanochromic luminescence quenching were investigated for a series of difluoroboron β-diketonate (BF2bdk) compounds.

Universalization of the Phase Diagram for a Model Rod-Coil Diblock Copolymer
TL;DR: In this paper, the Flory−Huggins interaction is measured for a model rod-coil block copolymer system, poly(alkoxyphenylenevinylene-b-isoprene), by fitting the interfacial segregation of block copolerant to a homopolymer interface and by using the random phase approximation (RPA) for block co-olymers.

Insight into entropy
TL;DR: In this article, the qualitative character of entropy has been investigated and several examples from statistical mechanics (including liquid crystal reentrant phases, two different lattice gas models, and the game of poker) demonstrate facets of this difficult question and point toward an answer.

Microscopic Theory of Reentrant Behavior in Liquid Crystals
TL;DR: In this article, a mean field approximation of the free energy of strongly polar liquid crystals was obtained. But the free energies were not expressed in terms of the amplitudes of these density waves, temperature T and di...

Tilt and temperature dependence of the pitch in the chiral smectic C phase
TL;DR: In this paper, the chirality of the constituent molecules in the chiral smectic phase induces a helical structure with a pitch, p 0, and the resulting pitch is described as a function of p 0 using the phenomenological theory of a chiral C phase.
Journal ArticleDOI
Role of end chains in the reentrant behavior of a nonpolar system.
TL;DR: These theories essentially show that the high-temperature smectic phase is an induced phase and the reentrant nematic phase is brought about by a competition between two incommensurate lengths.

Computer simulation of steady shear flow of liquid crystals with the Gay-Berne potential
TL;DR: In this paper, the SLLOD-type algorithm is applied to the steady shear flows of Gay-Berne fluids which are nematic in the equilibrium states, which exhibit shear-thinning in viscosity and non-zero first and second normal stress differences.
