Hydrodynamic cascade drives tumbling in sheared colloidal rod suspensions
Lucas H. P. Cunha, Paul F. Salipante, Peter D. Olmsted +1
Modeling the dynamics of colloidal rods remains a central challenge in soft-matter physics due to the anisotropic and long-ranged nature of their interactions. Hydrodynamic interac…
A Smoluchowski equation for a sheared suspension of frictionally interacting rods
Genevieve Quiñones, Peter D. Olmsted
In this work we develop constitutive equations for a dense, sheared suspension of frictionally interacting rods by applying Onsager's variational method as formulated by Doi. We tr…
The roles of elasticity and dimension in liquid-gel phase separation
Shichen Wang, Peter D. Olmsted
We compare six elastic models for polymer networks in the context of phase separation within a gel, including a new model that combines the finite extensible Arruda-Boyce model and…
Thermodynamics of microphase separation in a swollen, strain-stiffening polymer network
Carla Fernández-Rico, Robert W. Style, Stefanie Heyden +3
Elastic MicroPhase Separation (EMPS) provides a simple route to create soft materials with homogeneous microstructures by leveraging the supersaturation of crosslinked polymer netw…
Elastic turbulence in highly entangled polymers and wormlike micelles
Theo A. Lewy, Suzanne M. Fielding, Peter D. Olmsted +1
We show theoretically that an initially homogeneous planar Couette flow of a concentrated polymeric fluid is linearly unstable to the growth of two-dimensional (2D) perturbations,…
Nucleation of symmetric domains in the coupled leaflets of a bilayer
John J. Williamson, Peter D. Olmsted
We study the kinetics governing the attainment of inter-leaflet domain symmetry in a phase-separating amphiphilic bilayer. "Indirect" inter-leaflet coupling via hydrophobic mismatc…
Perspectives on the viscoelasticity and flow behavior of entangled linear and branched polymers
F. Snijkers, R. Pasquino, P. D. Olmsted +1
We briefly review the recent advances in the rheology of entangled polymers and identify emerging research trends and outstanding challenges, especially with respect to branched po…
Kinetics of symmetry and asymmetry in a phase-separating bilayer membrane
John J. Williamson, Peter D. Olmsted
We simulate a phase-separating a bilayer in which the leaflets experience a direct coupling favouring local compositional symmetry ("registered" bilayer phases), and an indirect co…
