Equilibrium and dynamic behaviours of dechiralisation lines occurring below SmC* cell boundaries in planar geometry constitute a polemic topic for several decades. We report new observations in the SmC* phase of the strongly polarised liquid crystal

Summary Background and Objectives Blood incompatibility arises from individual and ethnic differences in red blood cell (RBC) antigen profiles. This underlines the importance of documenting RBC antigen variability in various ethnic groups. Central As

Multiferroic materials are intensively investigated as potential candidates for a new generation of solar cells, due to the coexistence in their phases of ferroelectricity and magnetic order with low band gap. However, symmetry considerations, which

This letter describes an original freezing process that yields homogeneous solid films at ambient temperature with preservation of the layered structure of the chiral smectic phase. One of the most remarkable features of the process is its ability to

Recent experiments probing a new ferroelectric liquid crystal (CLF08) confined in cells with planar alignment have shown dielectric and optic anomalies suggesting the onset of ferrielectric ordering within the surface lattice of dechiralisation lines

We present a phenomenological model describing spatial modulations of the (anti)polarization in chiral tilted smectic phases. The helical instability of the polarization field direction combines with a second instability associated with the polarizat

Dual-polarized operation of satellite communications channels allows for an efficient use of the radio spectrum. A method for evaluating the availability of Ku- and Ka-band dual-polarized digital systems is described. It is based on long-term measure
