Edge pinning and transformation of defect lines induced by faceted colloidal rings in nematic liquid crystals
Bohdan Senyuk, Qingkun Liu, Ye Yuan +1
Nematic colloids exhibit a large diversity of topological defects and structures induced by colloidal particles in the orientationally ordered liquid crystal host fluids. These def…
Nematic liquid crystal boojums with handles on colloidal handlebodies
Qingkun Liu, Bohdan Senyuk, Mykola Tasinkevych +1
Topological defects that form on surfaces of ordered media, dubbed boojums, are ubiquitous in superfluids, liquid crystals (LCs), Langmuir monolayers, and Bose-Einstein condensates…
Topological colloids
Bohdan Senyuk, Qingkun Liu, Sailing He +4
Abundant in nature, colloids also find increasingly important applications in science and technology, ranging from direct probing of kinetics in crystals and glasses to fabrication…
Plasmonic complex fluids of nematiclike and helicoidal self-assemblies of gold nanorods with a negative order parameter
Qingkun Liu, Bohdan Senyuk, Jianwei Tang +4
We describe a soft matter system of self-organized oblate micelles and plasmonic gold nanorods that exhibit a negative orientational order parameter. Because of anisotropic surface…
Colloidal spirals in nematic liquid crystals
Bohdan Senyuk, Manoj B. Pandey, Qingkun Liu +2
One of the central experimental efforts in nematic colloids research aims to explore how the interplay between the geometry of particles along with the accompanying nematic directo…
Geometry-guided colloidal interactions and self-tiling of elastic dipoles formed by truncated pyramid particles in liquid crystals
Bohdan Senyuk, Qingkun Liu, Ephraim Bililign +2
The progress of realizing colloidal structures mimicking natural forms of organization in condensed matter is inherently limited by the availability of suitable colloidal building…
Colloidal Surfaces with Boundaries, Apex Boojums and Nested Elastic Self-Assembly of Nematic Colloids
Sungoh Park, Qingkun Liu, Ivan I. Smalyukh
Self-assembly of colloidal particles is poised to become a powerful composite material fabrication technique, but remains challenged by a limited control over the ensuing structure…
