A new lyotropic liquid crystal, potassium laurate, decylammonium chloride and water, which
has two uniaxial phases and a biaxial nematic phase, is reported. A surface of the phase …

The interactions of a lyotropic liquid crystal with boundary amorphous glass surfaces are
investigated using optical techniques. An unusual phenomenon is observed: the gliding of the …

The rubbing of polymer-coated substrates is one of the most frequently used techniques for
liquid crystal alignment. However, the aligning mechanisms are not completely understood. …

In the present work, we investigate the effect of two short phenylalanine-based peptides on
lipid membranes. A simplified model membrane composed of lecithin vesicles was used to …

In this paper we present to our knowledge the first light-scattering measurements on a
rather new lyotropic system potassium laurate, decylammonium chloride, H 2 O. Relative …

The alignment properties of lyotropic nematic liquid crystals (LNLC) on treated substrates
were studied. Hydrophobic vs hydrophilic surfaces as well as rubbed vs nonrubbed surfaces …

The surface reorientation process of a lyotropic liquid crystal is investigated in the calamitic (N
c) and biaxial (N bx) nematic phases. It is observed that the surface reorientation process …

We determine the anchoring strength (W) for a lyotropic liquid crystal in the nematic calamitic
phase. The sample holder is a microslide 200 μm thick (Vitro Dynamics) whose inner …

The contextualization of the scientific concepts presents itself as a pedagogical strategy to
make the curricular contents socially relevant and to promote greater articulation with the …

The development of patterned surfaces for liquid crystal (LC) alignment has attracted much
attention because it is applicable to bistable displays allowing the complete control of LC …
