Chirality Amplification and Deracemization in Liquid Crystals Open
Liquid crystal mesophases of achiral molecules are normally achiral, yet in a few materials they spontaneously deracemize and form right- and left-handed chiral domains. One mechanism that drives deracemization is molecular shape fluctuati…

Regulating Airflow Using Hybrid LCN for Soft Pneumatic Circuits Open
Being flexible and adaptive to various environments, soft robotics shows promise as a more robust alternative in many applications compared to traditional, rigid robotics. Of many employable different actuation strategies, pneumatically dr…

Spontaneous Optimal Mixing via Defect-Vortex Coupling in Confined Active Nematics Open
Active nematic flows in two dimensions, largely driven by motile $+1/2$ disclinations, mix themselves efficiently and exhibit chaos in the bulk steady state. Motivated by recent experimental findings for three-defect braiding in cardioid-s…

Frank-Read Mechanism in Nematic Liquid Crystals Open
In a crystalline solid under mechanical stress, a Frank-Read source is a pinned dislocation segment that repeatedly bows and detaches, generating concentric dislocation loops. We demonstrate that, in nematic liquid crystals, an analogous F…

Transforming patterned defects into dynamic poly-regional topographies in liquid crystal oligomers Open
We transform patterned defects into high-aspect-ratio poly-regional surface topographies. The active intricate textures are induced by generated shear forces under external stimuli.

Directing and reconfiguring colloidal assembly by disclination networks in nematic liquid crystal as templates Open
Exotic structures with interesting physical and chemical properties can be achieved by self-organizing engineered building blocks. The central aim for self-assembly is to precisely control the position and orientation of individual buildin…

Travelling colourful patterns in self-organized cellulose-based liquid crystalline structures Open
Cellulose-based systems are useful for many applications. However, the issue of self-organization under non-equilibrium conditions, which is ubiquitous in living matter, has scarcely been addressed in cellulose-based materials. Here, we sh…

Geometry and mechanics of disclination lines in 3D nematic liquid crystals Open
In nematic liquid crystals, disclination lines have several geometric features, which can be characterized by vectors and tensors. Based on these features, the mechanical forces on disclination lines can be calculated.

Dynamically morphing microchannels in liquid crystal elastomer coatings containing disclinations Open
Liquid crystal elastomers (LCEs) hold a major promise as a versatile material platform for smart soft coatings since their orientational order can be predesigned to program a desired dynamic profile. In this work, we introduce temperature-…
