Polarization features of polymer dispersed liquid crystal (PDLC) films were investigated experimentally. An alignment of PDLC films was achieved by a shear deformation of the films at an accurate control of geometric parameters. A numerical interpret

The birefringence and refractive indices of several liquid crystalline structures were measured throughout the visible wavelength region (400–900 nm) at different temperatures. Mixtures composed of members of the same homologous series were used in

In our search for systematic features we have studied the appearance of spontaneous polarisation in some simple cases of non-chiral smectic C mixtures with added chiral dopant. The electro-optic properties have been measured for each system and evalu

Our report is on the observation of thermoelectric phenomena in polymer dispersed nematic liquid crystal (PDLC). We have performed electro-optical measurements of the PDLC composite material based on both polyvinylbutiral and epoxy resin matrix. Desp

Achromatic phase retarders can be designed by combining two layers of birefringent materials with different dispersion of birefringence. We synthesized and studied several liquid crystalline structures in order to find combinations giving the best pe

A number of 1-(4-substituted phenyl)-2-(4-(alken-3-yl- 1)phenyl)ethynes have been synthesized by coupling of 4- substituted phenylacetylenes with new intermediates 1-(4'- iodophenyl)-alkenes-3, which were prepared by a reaction of either allylmagnesi
