Hydrodynamics in Semidilute Polyelectrolyte Solutions and Complex Coacervates

It is generally assumed that hydrodynamics in dense polyelectrolyte (PE) solutions, such as semidilute PE solutions and PE complex coacervates, is heavily screened and inconsequential. Here, using mesoscale molecular dynamics that explicitly accounts

GCMe: Efficient implementation of the Gaussian core model with smeared electrostatic interactions for molecular dynamics simulations of soft matter systems

Autor: Ye, Benjamin Bobin, Chen, Shensheng, Wang, Zhen-Gang

In recent years, molecular dynamics (MD) simulations have emerged as a pivotal tool for understanding the structure, dynamics, and phase behavior in charged soft matter systems. To explore phenomena across greater length and time scales in MD simulat

Charge Asymmetry Suppresses Coarsening Dynamics in Polyelectrolyte Complex Coacervation

Autor: Chen, Shensheng, Wang, Zhen-Gang

Mixing solutions of oppositely charged macromolecules can result in liquid-liquid phase separation into a polymer-rich coacervate phase and a polymer-poor supernatant phase. Here we show that charge asymmetry in the constituent polymers can slow down

Polyelectrolyte Knot Delocalization Induced by Counterion Condensation

Autor: Chen, Shensheng, Zhou, Tingtao

Knots on ring polymers tend to be tight. For knots on charged polymers (polyelectrolytes), electrostatic repulsion among the monomers is considered to enhance the persistence length and further localize the knots. However, the effects of counterion c
