Thermal Breakage and Self-Healing of a Polymer Chain under Tensile Stress
A. Ghosh, D. I. Dimitrov, V. G. Rostiashvili +2
We consider the thermal breakage of a tethered polymer chain of discrete segments coupled by Morse potentials under constant tensile stress. The chain dynamics at the onset of frac…
Capillary filling with wall corrugations] Capillary filling in microchannels with wall corrugations: A comparative study of the Concus-Finn criterion by continuum, kinetic and atomistic approaches
S. Chibbaro, E. Costa, D. Dimitrov +5
We study the impact of wall corrugations in microchannels on the process of capillary filling by means of three broadly used methods - Computational Fluid Dynamics (CFD), Lattice-B…
Dynamics of a stretched nonlinear polymer chain
M. Febbo, A. Milchev, V. Rostiashvili +2
We study the relaxation dynamics of a coarse-grained polymer chain at different degrees of stretching by both analytical means and numerical simulations. The macromolecule is model…
Universal properties of a single polymer chain in slit: Scaling versus MD simulations
Dimitar I. Dimitrov, Andrey Milchev, Kurt Binder +2
We revisit the classical problem of a polymer confined in a slit in both of its static and dynamic aspects. We confirm a number of well known scaling predictions and analyse their…
Forced Imbibition - a Tool for Determining Laplace Pressure, Drag Force and Slip Length in Capillary Filling Experiments
D. I. Dimitrov, A. Milchev, K. Binder
When a very thin capillary is inserted into a liquid, the liquid is sucked into it: this imbibition process is controlled by a balance of capillary and drag forces, which are hard…
Capillary Rise in Nanopores: Molecular Dynamics Evidence for the Lucas-Washburn Equation
D. I. Dimitrov, A. Milchev, K. Binder
When a capillary is inserted into a liquid, the liquid will rapidly flow into it. This phenomenon, well studied and understood on the macroscale, is investigated by Molecular Dynam…
