The micrograph shows the texture of the SmI phase observed during cooling for hockey stick-shape pure compound at 85°C. The image was taken with a polarizing optical microscope (Olympus) with crossed polarizers and equipped with the Linkam TMSH 600 hot stage and the Linkam TMS 93 temperature controller.

Jury comment

This month's image is striking, because beautiful and vivid color discrimination is observed for birefringent colors maybe for different tilt directions.

Dorota Węgłowka received her MSc in the Faculty of Chemistry from Warsaw University of Technology (Poland) and her PhD in the Faculty of Advanced Technologies and Chemistry from Military University of Technology with a thesis on the synthesis of highly tilted ferroelectric liquid crystals, supervised by Prof. Roman Dąbrowski. Then she worked for Volfoni company (Paris, France) on active 3D shutter glasses. Her current research interests are mainly focussed on synthesis and investigation of ferroelectric as well as nematic (high birefringent, dual-frquency addressing systems) liquid crystals for photonic applications.
