Consolute critical point for two smectic-Aphases

Autor: H. T. Nguyen, Robert J. Twieg, G. Sigaud, M. F. Achard

Publikováno v: Physical Review Letters. 65:2796-2799

This paper describes the first example of a consolute critical point associated with phase separation in a binary system of smectic liquid crystals. In particular, a homogeneous smectic-A mixture of a polar compound with an aliphatic tail and a nonpo

26 pages, 5 figures; International audience; Deformations that conserve the parallelism and the distances --between layers, in smectic phases; between columns, in columnar phases-- are commonplace in liquid crystals. The resulting deformed textures h

Observed under the polarizing microscope, the B7bis phase in the banana compound D14F3 [J.P. Bedel et al, Liq. Cryst., 27, 1411 (2000)] displays two types of textures of defects, namely (a): helical ribbons, that nucleate in large quantities when the

Laterally attached liquid crystalline polymers as stationary phases in reversed-phase high-performance liquid chromatography. V. Study of retention mechanism using linear solvation energy relationships

Autor: F, Gritti, G, Félix, M F, Achard, F, Hardouin

Publikováno v: Journal of chromatography. A. 922(1-2)

A linear solvation energy relationship model was used to characterize the retention behavior of a stationary phase based upon a nematic side-on liquid crystalline polymer (SOLCP) in reversed-phase liquid chromatography. The set of solutes was constit

Liquid crystalline polymers as stationary phases. IV. Chemical bonding and immobilization of the polymer on silica characterization by solid-state nuclear magnetic resonance spectroscopy

Autor: F, Gritti, I, Terrien, S, Menu, E J, Dufourc, G, Félix, M F, Achard, F, Hardouin

Publikováno v: Journal of chromatography. A. 922(1-2)

Chemical bonding reaction and immobilization through low energy radiation (heating) have been investigated to fix a side-chain liquid crystalline polymer (SC-LCP) on silica particles in order to use the resulting modified silica in normal-phase HPLC.

Autor: F, Gritti, G, Félix, M F, Achard, F, Hardouin

Publikováno v: Journal of chromatography. A. 913(1-2)

Specific stationary phases based upon non-liquid-crystalline polymers, liquid-crystalline molecules and side-on fixed liquid-crystalline polymers (SO-LCP) have been synthesized for use as silica modified stationary phases in high-performance liquid c

Phase separation in nematic and smectic a phases

Autor: H. Richard, M. Mauzac, Huu Tinh Nguyen, H. Gasparoux, M. F. Achard, F. Hardouin, G. Sigaud

Publikováno v: Phase Transitions. 33:249-251

Until recently no example was known with a miscibility gap separating two non-ordered mesophases (i.e.: nematic, smectic A or C) of the same symmetry. In most cases of binary solutions it was observed that either the phase diagram is of the simple eu

Phase Behavior of High- and Low-Molar-Mass Liquid Crystal Mixtures

Publikováno v: Partially Ordered Systems ISBN: 9781461383352

Over the past twenty years a rough estimate of the literature related to the physics and chemistry of liquid crystalline mixtures amounts to 5000 references! Our purpose is thus neither to present an exhaustive review nor to justfy the interest in th
