Topological defects and geometric memory across the nematic-smectic A liquid crystal phase transition
Ahram Suh, Min-Jun Gim, Daniel Beller +1
We study transformations of self-organized defect arrays at the nematic-smectic A liquid crystal phase transition, and show that these defect configurations are correlated, or "rem…
Fast Fabrication of Sub-200-nm Nanogrooves using Liquid Crystal Material
Dae Seok Kim, Yun Jeong Cha, Min-Jun Gim +1
Self-assembly of soft materials attracts keen interest for patterning applications owing to its ease and spontaneous behavior. We report the fabrication of nanogrooves using sublim…
Chiral nematic self-assembly of minimally surface damaged chitin nanofibrils and its load bearing functions
Dongyeop X. Oh, Yun Jeong Cha, Hoang-Linh Nguyen +4
Chitin is one of the most abundant biomaterials in nature, with 10^10 tons produced annually as hierarchically organized nanofibril fillers to reinforce the exoskeletons of arthrop…
Linkage-length dependent structuring behaviour of bent-core molecules in helical nanostructures
Hanim Kim, Anna Zep, Seong Ho Ryu +6
We studied the correlation between the molecular structure and the formation of helical nanofilaments (HNFs) of bent-core dimeric molecules with varying linkage lengths. To obtain…
Controlling Gaussian and mean curvatures at microscale by sublimation and condensation of smectic liquid crystals
Dae Seok Kim, Yun Jeong Cha, Mun Ho Kim +2
Soft materials with layered structure such as membranes, block copolymers, and smectics exhibit intriguing morphologies with nontrivial curvatures. We report on restructuring the G…
