Revision as of 10:40, 25 October 2017
The meeting takes place every three weeks on Tuesday at 10:30, if not indicated differently.
- 24.10.2017 Jonas: Poisson-Boltzmann Cell Model under Tension, correct treatment and results. Discussed why results for (single chain) PB Cell Model differ from Tobis MD results for gels (see the presentation File:Poisson Boltzmann Cell Model Progress Report 24.10.2017.odp).
- 9.05.2017 Kai: Autocorrelation time of confined polymers, Patrick: made COMSOL implementation of Cell Model, Jonas: discussed working together with Peters on weak polyelectrolytes in poor solvents and working with Peter on bulk vs. local pH values, David: mobility of weak stars, Michael: Problems with reactive boundary condition and momentum conservation
- F. Weik: B-spline fit to polymer conformations and error calculation for Eigenvalue problems (both related to Evangelos' project of DNA translocation).
- P. Kreissl: Writing proposal for magnetic gels project together with R. Weeber.
- K. Szuttor: Writing response to paper review (almost done).
- M. Kuron: Bachelor student's thesis deadline is soon. Moving boundary EK debugging progresses, but not finished. Literature resesearch on visco-elastic LB: -Malas-Pinas model may not be the best choice acc. to Joost et al. -Flo: talk to U. Schiller
- 28.03.2017 We discussed results from the DPG meeting (e.g. Microgels from the group of Richtering, Aachen, https://sharepoint.ecampus.rwth-aachen.de/vo/microgels/aussen/SitePages/Publications.aspx), strategies for moving L-shaped swimmers and simulating weak hydrogels in an external electric field.
- 28.02.2017 Jonas: We discussed the Poisson Boltzmann Cell Model, the free energy contributions which are necessary to determine the swelling equilibrium and first results of the COMSOL model.
- 7.02.2017 Kai: We discussed the relaxation time behaviour of the first Rouse mode for uncharged polymers tethered to a wall in the presence of hydrodynamic interactions. There seems to be a crossover for the relaxation times, depending on the channel height and polymer length.
- 18.01.2017 Julia presented the Computation of the 'Morphological Computation' for L shaped active swimmers. Nicolai presented results not included in his master thesis: susceptibilities/ relaxation times/ magnetization for isotropic/ uniaxial magnetic gels regarding the influence of Hydrodynamics (LB vs. Langevin thermostat). Idea of simulating ferro fluids due to more experimental data.
- 22.11.2016 Presentation of the Desalination Paper of Tobias, Progress report of Patrick (active colloid in viscous medium modeled by entangled protein solution)
- 13.1.2016 Patrick: Discussed how to test in simulations the magnetization model of anisotropic particles in an external magnetic field in an elastic medium. Further discussed why an active colloid in a viscoelastic medium could have an increased rotational diffusion. Kai: presented his paper on polymer stretching.
