Dynamics and Rheology of Ring-Linear Blend Semidilute Solutions in Extensional Flow: Single Molecule Experiments
Yuecheng Zhou, Charles D. Young, Kathryn E. Regan +7
Ring polymers exhibit unique flow properties due to their closed chain topology. Despite recent progress, we have not yet achieved a full understanding of the nonequilibrium flow b…
Dynamics and Rheology of Ring-Linear Blend Semidilute Solutions in Extensional Flow: Modeling and Molecular Simulations
Charles D. Young, Yuecheng Zhou, Charles M. Schroeder +1
We use Brownian dynamics (BD) simulations and single molecule experiments to investigate the influence of topological constraints and hydrodynamic interactions on the dynamics and…
Viscoelastic properties of ring-linear DNA blends exhibit non-monotonic dependence on blend composition
K. R. Peddireddy, M. Lee, C. M. Schroeder +1
Entangled ring polymers, along with blends of ring and linear polymers, continue to be a topic of great interest and debate due to the conflicting experimental results in the liter…
Double-mode relaxation of highly deformed vesicles
Dinesh Kumar, Channing M. Richter, Charles M. Schroeder
Lipid vesicles are known to undergo complex conformational transitions, but it remains challenging to systematically characterize non-equilibrium membrane shape dynamics. Here, we…
Unexpected entanglement dynamics in semidilute blends of supercoiled and ring DNA
Karthik R. Peddireddy, Megan Lee, Yuecheng Zhou +4
Blends of polymers of different topologies, such as ring and supercoiled, naturally occur in biology and often exhibit emergent viscoelastic properties coveted in industry. However…
Flow topology during multiplexed particle manipulation using a Stokes Trap
Anish Shenoy, Dinesh Kumar, Sascha Hilgenfeldt +1
Trapping and manipulation of small particles underlies many scientific and technological applications. Recently, the precise manipulation of multiple small particles was demonstrat…
