Localized elasticity governs the nonlinear rheology of colloidal supercooled liquids
Dejia Kong, Wei-Ren Chen, Ke-Qi Zeng +2
We propose a microscopic picture for understanding the nonlinear rheology of supercooled liquids with soft-repulsive potentials. Based on Brownian dynamics simulations of supercool…
Size and shape fluctuations of ultrasoft colloids
Huarui Wu, Jing Song, Wei-Ren Chen +3
Ultrasoft colloidal particle fluctuates due to its flexibility. Such fluctuation is essential for colloidal structure and dynamics, but is challenging to quantify experimentally. W…
Microstructural understanding of the length and stiffness dependent shear thinning in semi-dilute colloidal rods
Christian Lang, Joachim Kohlbrecher, Lionel Porcar +4
Complex fluids containing low concentrations of slender colloidal rods can display a high viscosity, while little flow is needed to thin the fluid. This feature makes slender rods…
Scaling Behavior of Anisotropy Relaxation in Deformed Polymers
Christopher N. Lam, Wen-Sheng Xu, Wei-Ren Chen +12
Drawing an analogy to the paradigm of quasi-elastic neutron scattering, we present a general approach for quantitatively investigating the spatiotemporal dependence of structural a…
Dynamically Correlated Region in Sheared Colloidal Glasses Revealed by Neutron Scattering
Zhe Wang, Takuya Iwashita, Lionel Porcar +6
The microscopic deformation mechanism of charged colloidal glasses with extended-range interactions under shear is investigated by in-situ small-angle neutron scattering, and a dyn…
Dynamic Equivalence between Soft Star Polymers and Hard Spheres
Zhe Wang, Antonio Faraone, Panchao Yin +5
Understanding the dynamics of soft colloids, such as star polymers, dendrimers, and microgels, is of scientific and practical importance. It is known that the excluded volume effec…
