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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.

Molecular Models for the Ferroelectric Smectic C* Phase
Mikhail A. Osipov,S. A. Pikin +1 more
TL;DR: In this article, a molecular model is proposed which is used to explain both ferroelectric and flexoelectric properties of the C* phase using a small number of molecular model parameters.

X-Ray Investigations of a Reentrant Nematic Phase Formed of Terminal-Nonpolar Compounds
TL;DR: In this article, a binary system of terminal nonpolar compounds was presented in which a stable reentrant nematic phase occurs and X-ray investigations were carried out in the N, SA, Nre, and SC phase.

Vapour-liquid and gas-gas equilibria in simple systems: VI. The critical exponents βP and βT of the system neon-xenon
TL;DR: In this article, the shape of the coexistence surface of the system neon-xenon has been determined in great detail, in the neighbourhood of the critical line, by means of isobaric measurements.
