Mechanical response of quasi-two-dimensional colloidal clusters under uniaxial tension
Yanhui Yang, Jiawei Kang, Yao Li +1
Despite extensive studies of equilibrium conformations of colloidal clusters, little is known about their mechanical response. Here, we investigate the tensile behavior of a quasi-…
Mode-locking in a colloidal ring driven by power-modulated optical tweezers
Muyang Huang, Pik-Yin Lai, Xiaoguang Ma
Particles and clusters moving across real-space periodic potentials can become locked to discrete directions or orientations due to competing symmetries. Here, we demonstrate an an…
Scaling of relaxation and excess entropy in plastically deformed amorphous solids
K. L. Galloway, Xiaoguang Ma, Nathan C. Keim +3
When stressed sufficiently, solid materials yield and deform plastically via reorganization of microscopic constituents. Indeed, it is possible to alter the micro-structure of mate…
Formation of stable aggregates by fluid-assembled solid bridges
Ali Seiphoori, Xiao-guang Ma, Paulo E. Arratia +1
When a colloidal suspension is dried, capillary pressure may overwhelm repulsive electrostatic forces, assembling aggregates that are out of thermal equilibrium. This poorly unders…
