Charged weak hydrogels from a computational perspective — the complexity of Coulomb interactions and how to reduce them
Christian Holm (University of Stuttgart)


In my talk I will present our research on how to study the pH response of weak hydrogels. I will introduce our Grand Reaction ensemble method to realistically model the pH-response, and also several abstractions on the methodological level on how to treat charged networks in a reasonable time. I will give several example studies on strong as well as weak gels, on polyelectrolyte stars, and also present a solution to the recently observed giant pKa shift in weak polyelectrolyte brushes.
