Tension dynamics in semiflexible polymers. Part I: Coarse-grained equations of motion
Oskar Hallatschek, Erwin Frey, Klaus Kroy
Based on the wormlike chain model, a coarse-grained description of the nonlinear dynamics of a weakly bending semiflexible polymer is developed. By means of a multiple scale pertur…
Tension dynamics in semiflexible polymers. Part II: Scaling solutions and applications
Oskar Hallatschek, Erwin Frey, Klaus Kroy
In Part I of this contribution, a systematic coarse-grained description of the dynamics of a weakly-bending semiflexible polymer was developed. Here, we discuss analytical solution…
Charge inversion at minute electrolyte concentrations
J. Pittler, W. Bu, D. Vaknin +3
Anionic DMPA monolayers spread on LaCl solutions reveal strong cation adsorption and a sharp transition to surface overcharging at unexpectedly low bulk salt concentrations. We…
Entropy-induced separation of star polymers in porous media
V. Blavats'ka, C. von Ferber, Yu. Holovatch
We present a quantitative picture of the separation of star polymers in a solution where part of the volume is influenced by a porous medium. To this end, we study the impact of lo…
Stretching dynamics of semiflexible polymers
B. Obermayer, O. Hallatschek, E. Frey +1
We analyze the nonequilibrium dynamics of single inextensible semiflexible biopolymers as stretching forces are applied at the ends. Based on different (contradicting) heuristic ar…
