Chelipeds-like defects in nematic dimer

Description
The LC image corresponds to a nematic liquid crystal optical texture exhibiting chelipeds-like defects representing nature's delicate phase of matter. It is somehow relating the beauty of liquid crystalline material with that of a living organism like a rock crab. This optical texture is obtained at 109 °C (under crossed polarizers) during the cooling from the isotropic temperature of a nematic liquid crystal compound composed of two units of (E)-1-(4-butylphenyl)-2-(4-methoxyphenyl)diazene connected via flexible spacers. This POM image has been recorded in a joint project with Prof. A. K. Prajapati from M.S. University, Vadodara, India.

Jury comment
The photo shows once again how liquid crystals combine science and artistic aspects, so the picture is very attractive from an aesthetic and artistic point of view.
