WebThe rod-shaped dicroic dye molecules strongly absorb the light polarized parallel to the long axis direction, showing only a weak absorption in the orthogonal direction. The type of bonding between the dye and the liquid crystal molecules tends to align the former parallel to the director and to follow its orientation. WebNeedle and rod shaped crystals pose special challenges. They are easily cracked and broken during retrieval. They are difficult to position over or within the aperture of standard circular-aperture loops. When loop mounted, they tend to be surrounded by too much liquid.

Web27 May 2024 · MSU crystals are more easily detected and identified using PLM than with OLM, as they all show intense birefringence with negative elongation properties. MSU … WebThese liquid crystalline phases are closer in architecture to thermotropic liquid crystalline phases than to the conventional lyotropic phases. In contrast to the behaviour of amphiphilic molecules, the lyotropic behaviour of the rod-like molecules does not involve self-assembly.
