He is currently pursuing PhD at Applied Chemistry Department, The Maharaja Sayajirao University of Baroda, Vadodara, India under the guidance of Prof. R. C. Tandel. His work includes the design, synthesis, photo physical properties and biological evaluation of bent shaped and calamitic mesogens with heterocyclic moiety. His main focus is to study the effect of terminal alkyl chain, lateral substitution and also the photoluminescent properties.

This Smectic-A phase was observed in 4,4’-alkoxy benzylidene amino phenyl cholesteryl carbonate. This specific image was observed for 4-n-decyloxy aniline derivative. Upon cooling from isotropic melt first the formation of a chiral nematic mesophase takes place which on further cooling generates the focal conic textures of Smectic-A phase (∼ 220°C ). The sample was sandwiched between the untreated glass slides and observed under the cross polarizer in heating and cooling cycles. The size bar of the image is approximately 500 μm.
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.
