Featured Liquid Crystal Picture Art of the Month
The picture shows chiral nematic liquid crystal droplets dispersed in glycerol, captured under a polarizing optical microscope (Eclipse LV100POL, Nikon) in the reflection mode. The pitch of the chiral nematic is ~270 nm, and the droplets are about 10's–200 μm in diameter. In a submillimeter-sized chiral nematic droplet, the surface anchoring exerted by the glycerol is not strong enough to stabilize the entire droplet into a well-aligned planar texture. One finds that the large droplets exhibit some quasi-periodic fluctuations in the color of reflection. In addition, owing to the stirring procedure during the fabrication, it seems that the droplets were lined up in orbits, just like a microscopic version of a galaxy.
The image is nicely balanced. The composition is distinguished by a dynamic diagonal arrangement of the LC droplets. It is a lovely motif for the winter holidays.
