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.

Theory of the blue phase of cholesteric liquid crystals.
TL;DR: In this paper, a theory of the cholesteric blue phase is presented, assuming a first-order Cholesteric-isotropic transition, and it is shown that the planar helix structure becomes unstable at temperatures near the transition point.
