Description

This texture shows a twist-bend nematic phase formed inside a round capillary tube (inner diameter is 200 microns). The pictures was taken using a polarizing optical microscope without an analyzer.

Jury comment

I chose this, simply because I thought that it is interesting. There is a certain periodicity in the formation of the filaments from the surrounding round capillary wall. Interestingly, the surface of the liquid crystal also shows the periodic morphology of a peculiar complex structure. Are there any important insights into the physical properties of the Ntb phase hidden in the picture?
