Solubility of poorly soluble species in bulk and nanopores from grand-canonical Wang-Landau sampling
Russell Kajouri, Adyant Agrawal, Philipp Stärk +2
Poorly soluble species can have mean populations below one in small systems such as nanopores. In this regime, the grand-potential minimum, which identifies the most probable parti…
A Generalized Grand-Reaction Method for Modelling the Exchange of Weak (Polyprotic) Acids between a Solution and a Weak Polyelectrolyte Phase
David Beyer, Christian Holm
We introduce a Monte-Carlo method that allows for the simulation of a polymeric phase containing a weak polyelectrolyte, which is coupled to a reservoir at a fixed pH, salt concent…
Explaining Giant Apparent Shifts in Weak Polyelectrolyte Brushes
David Beyer, Peter Košovan, Christian Holm
Recent experiments on weak polyelectrolyte brushes found marked shifts in the effective p that are linear in the logarithm of the salt concentration. Comparing explic…
Optimal motility strategies for self-propelled agents to explore porous media
Christoph Lohrmann, Christian Holm
Micro-robots for, e.g., biomedical applications, need to be equipped with motility strategies that enable them to navigate through complex environments. Inspired by biological micr…
Ratcheting charged polymers through symmetric nanopores using pulsed fields: Designing a low pass filter for concentrating DNA
Le Qiao, Kai Szuttor, Christian Holm +1
We present a new concept for the separation of DNA molecules by contour length that combines a nanofluidic ratchet, nanopore translocation and pulsed fields. Using Langevin Dynamic…
Order and Information in the Patterns of Spinning Magnetic Micro-disks at the Air-water Interface
Wendong Wang, Gaurav Gardi, Paolo Malgaretti +9
The application of the Shannon entropy to study the relationship between information and structures has yielded insights into molecular and material systems. However, the difficult…
