International audience; The Bragg reflections from icosahedral quasicrystals obtained in the course of a computer experiment on the simulation of crystal growth have been studied. The computer experiments based on the theory developed earlier allow o

Grain boundaries and the law of corresponding cones in smectics

Autor: Oleg D. Lavrentovich, M. Kléman

Publikováno v: The European Physical Journal E. 2:47-57

Focal Conic Domains (FCDs) in smectic phases often assemble according to a particular rule, experimentally discovered by G. Friedel, the law of corresponding cones (l.c.c.). This paper reports various results relating to this type of association. Fir

Defects in Liquid-Crystalline Polymers

Autor: M. Kléman

Publikováno v: MRS Bulletin. 20:23-28

The properties of imperfections (or defects) of the atomic or molecular order in condensed matter can be conveniently described under two headings: (1) Topological properties—Defects break a specific symmetry of the ordered system at a local scale,

Transmission electron microscopy analysis of planar and line defects in an Al-Li-Cu icosahedral quasicrystal

Autor: M. Kléman, Nadine Baluc, Dapeng Yu

Publikováno v: Philosophical Magazine Letters. 72:1-9

Transmission electron microscopy observations of as-cast samples of an Al-Li-Cu icosahedral quasicrystal allowed us to demonstrate planar and line defects. By means of dark-field and weak-beam imaging techniques, planar defects were tentatively ident

Nucleation of focal conic domains in smectic A liquid crystals

Autor: V. M. Pergamenshchik, Oleg D. Lavrentovich, M. Kléman

Publikováno v: Journal de Physique II. 4:377-404

The first-order structural transitions caused by an external magnetic field or by a surface anchoring are considered for a smectic A liquid crystal in the restricted geometry of a flat cell. The transition occurs by nucleation of focal conic domains.
