Dae-Yoon Kim obtained his B.S. and M.S. degrees from Chonbuk National University in 2010 and 2012, respectively. Later in 2013 he received a Global Ph.D. Fellowship (GPF) from the National Research Foundation of Korea (NRF) to complete his research project. Currently, he is a Ph.D. candidate in the Advanced Molecular Engineering Laboratory (AMEL) group at the Department of the Polymer-Nano Science and Technology, Chonbuk National University, Korea. His graduate research topic is the synthesis and characterization of light-responsive soft matter under supervision of Prof. Kwang-Un Jeong. His research interests focus on the nano- to macro-scale molecular and supramolecular assemblies for the flexible photonic crystal, patternable functional film and remote controllable sensor.

Circus of the sun: The microphotograph shows the growth of spherulite with strong birefringence during the direct crystallization from the isotropic melt of chiral mesogenic compound. The optical texture was monitored on the glass substrate at 120 °C by using cross-polarized microscopy (Nikon ECLIPSE) coupled with a heating stage (Linkam LTS).


Jury comment: The polarized optical microscopy image shows very unusual colorful circles, in which green, yellow, and red colors can be revealed even at the Maltese cross patterns.
