"The Chromatic Tempest"

Stacks Image 68


This is polarized optical microscopy image of the compound cholesteryl perlagonate at a temperature of 73.6 degrees Celsius at the transformation of the SmA* phase to the TGBA* phase, which is coming in from the left-hand side. The phase transition is marked by rapid changes in colour with the same contrast and ferocity as the wind at the onset of a storm.

Jury comment

This picture represents a nice example of color and texture change during transformation from the  SmA* to the TGBA* phase.
