Visualizing Energy Transfer Between Redox-Active Colloids
Subing Qu, Zihao Ou, Yavuz Savsatli +17
Redox-based electrical conduction in nonconjugated polymers has been explored less than a decade, yet is already showing promise as a new concept for electrical energy transport. H…
Vesicle dynamics in large amplitude oscillatory extensional flow
Charlie Lin, Dinesh Kumar, Channing M. Richter +3
Although the behavior of fluid-filled vesicles in steady flows has been extensively studied, far less is understood regarding the shape dynamics of vesicles in time-dependent oscil…
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…
Orientation control and nonlinear trajectory tracking of colloidal particles using microfluidics
Dinesh Kumar, Anish Shenoy, Songsong Li +1
Suspensions of anisotropic Brownian particles are commonly encountered in a wide array of applications such as drug delivery and manufacturing of fiber-reinforced composites. Techn…
Dynamically Heterogeneous Relaxation of Entangled Polymer Chains
Yuecheng Zhou, Charles M. Schroeder
Stress relaxation following deformation of an entangled polymeric liquid is thought to be affected by transient reforming of chain entanglements. In this work, we use single molecu…
Single Polymer Dynamics for Molecular Rheology
Charles M. Schroeder
Single polymer dynamics offers a powerful approach to study molecular-level interactions and dynamic microstructure in materials. Direct visualization of single chain dynamics has…
Direct observation of DNA dynamics in semi-dilute solutions in extensional flow
Kai-Wen Hsiao, Chandi Samsal, J. Ravi Prakash +1
The dynamic behavior of semi-dilute polymer solutions is governed by an interplay between solvent quality, concentration, molecular weight, and flow type. Semi-dilute solutions are…
Parameter-free prediction of DNA dynamics in planar extensional flow of semidilute solutions
Chandi Sasmal, Kai-Wen Hsiao, Charles M. Schroeder +1
The dynamics of individual DNA molecules in semidilute solutions undergoing planar extensional flow is simulated using a multi-particle Brownian dynamics algorithm, which incorpora…
