Description

This image exhibits phase transition from the cholesteric phase on the left to the twist-bend nematic phase on the right. The material is a mixture of the bent flexible dimer CB7CB and the rod-like chiral dopant CB15. The cell is a commercial cell with unidirectional alignemnt in the horizontal direction. Picture width is 950 microns.

Jury comment

Again the selected photo is from the twist-bend nematic phase. The transformation from Ch (left) to NTB (right) looks like the Sun and the solar wind stream.
