The mechanics of disclination emergence in 3D active nematics
Yingyou Ma, Christopher Amey, Aparna Baskaran +1
The spontaneous creation of disclinations is a defining characteristic of active nematics, which is rarely observed in equilibrium systems or other active matter systems. Thus, und…
Magic sizes enable minimal-complexity, high-fidelity assembly of programmable shells
Botond Tyukodi, Fernando Caballero, Daichi Hayakawa +4
Recent advances in synthetic methods enable designing subunits that self-assemble into structures with precise, finite sizes and well-defined architectures, but yields are frequent…
From toroids to helical tubules: Kirigami-inspired programmable assembly of two-periodic curved crystals
Mason Price, Daichi Hayakawa, Thomas E. Videbæk +6
Biology is full of intricate molecular structures whose geometries are inextricably linked to their function. Many of these structures exhibit varying curvature, such as the helica…
Active noise-induced dynamic clustering of passive colloids
Layne B. Frechette, Aparna Baskaran, Michael F. Hagan
Active fluids generate spontaneous, often chaotic mesoscale flows. Harnessing these flows to drive embedded soft materials into structures with controlled length scales and lifetim…
Measuring multisubunit mechanics of geometrically-programmed colloidal assemblies via cryo-EM multi-body refinement
Thomas E. Videbæk, Daichi Hayakawa, Michael F. Hagan +3
Programmable self-assembly has recently enabled the creation of complex structures through precise control of the interparticle interactions and the particle geometries. Targeting…
Achieving designed texture and flows in bulk active nematics using optimal control theory
Saptorshi Ghosh, Aparna Baskaran, Michael F. Hagan
Being intrinsically nonequilibrium, active materials can potentially perform functions that would be thermodynamically forbidden in passive materials. However, active systems have…
