Elasticity-Dependent Self-assembly of Micro-Templated Chromonic Liquid Crystal Films
Matthew A. Lohr, Marcello Cavallaro, Daniel A. Beller +4
We explore micropatterned director structures of aqueous lyotropic chromonic liquid crystal (LCLC) films created on square lattice cylindrical-micropost substrates. The structures…
Exploiting imperfections: Directed assembly of surface colloids via bulk topological defects
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
We exploit the long-ranged elastic fields inherent to confined nematic liquid crystals to assemble colloidal particles trapped at the liquid crystal interface into reconfigurable s…
Ring around the colloid
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
In this work, we show that Janus washers, genus-one colloids with hybrid anchoring conditions, form topologically required defects in nematic liquid crystals. Experiments under cro…
Micro-Bullet Assembly: Interactions of Oriented Dipoles in Confined Nematic Liquid Crystal
Mohamed Amine Gharbi, Marcello Cavallaro, Gaoxiang Wu +4
Microbullet particles, cylinders with one blunt and one spherical end, offer a novel platform to study the effects of anisotropy and curvature on colloidal assembly in complex flui…
