Functional trends and rheological evaluation of polyurethane microcapsules in dermato-cosmetic applications
Sharadwata Pan, Andreas Wierschem, Natalie Germann +1
To date, natural and synthetic polymer-based microcapsules have been used extensively in various dermato-cosmetic applications, with an emphasis on the targeted delivery of active…
Static Dielectric Permittivity Profiles and Coarse-graining Approaches for Water in Graphene Slit Pores
Philipp Stärk, Henrik Stooß, Philip Loche +3
The dielectric response of nano-confined fluids is crucial across technologies and biological systems, yet its calculation and interpretation from molecular simulations are often m…
Response to dynamic shape changes in suspensions of hard rectangles
Denis Dertli, Thomas Speck
While the autonomous assembly of hard nanoparticles with different shapes has been studied extensively both in experiment and simulations, little is known about systems where parti…
Statistics and morphologies of stable droplets in scalar active fluids
Kathrin Hertäg, Joshua F. Robinson, Thomas Speck
Conventional phase segregation is controlled by a positive interfacial tension, which implies that the system relaxes towards a state in which the interfacial area (or length) is m…
Negative drag force on beating flagellar-shaped bodies in active fluids
Timo Knippenberg, Robin Bebon, Thomas Speck +1
We experimentally investigate the drag force exerted by a suspension of light-induced active particles (APs) on a translating and beating idealized flagellum-shaped object realized…
Singular density correlations in chiral active fluids in three dimensions
Yuta Kuroda, Takeshi Kawasaki, Kunimasa Miyazaki
We investigate density fluctuations in three-dimensional chiral active fluids by using a simple model of helical self-propelled particles. Helical motion is generated by a constant…
Azimuthal variation of apparent contact angles on structured surfaces featuring micrometric ramps, pyramids and staggered cubes at two different inherent wettabilities
P. Palmetshofer, S. Hengsbach, M. Guttmann +2
As new manufacturing methods enable manufacturing of microstructured surfaces with varying structure geometries, questions remain on some effects on the wetting behavior and the re…
In pursuit of the tetratic phase in hard rectangles
Denis Dertli, Thomas Speck
We numerically investigate two-dimensional systems of hard rectangles at constant pressure through extensive hard-particle Monte Carlo simulations. We determine the complete phase…
Coarse-grained models for phase separation in DNA-based fluids
Soumen De Karmakar, Thomas Speck
DNA is now firmly established as a versatile and robust platform for achieving synthetic nanostructures. While the folding of single molecules into complex structures is routinely…
Universal limiting behaviour of reaction-diffusion systems with conservation laws
Joshua F. Robinson, Thomas Machon, Thomas Speck
Making sense of complex inhomogeneous systems composed of many interacting species is a grand challenge that pervades basically all natural sciences. Phase separation and pattern f…
Crowding-Regulated Binding of Divalent Biomolecules
Tomasz Skóra, Mathijs Janssen, Andreas Carlson +1
Macromolecular crowding affects biophysical processes as diverse as diffusion, gene expression, cell growth, and senescence. Yet, there is no comprehensive understanding of how cro…
Thermodynamics of active matter: Tracking dissipation across scales
Robin Bebon, Joshua F. Robinson, Thomas Speck
The concept of entropy has been pivotal in the formulation of thermodynamics. For systems driven away from thermal equilibrium, a comparable role is played by entropy production an…
pyMBE: the Python-based Molecule Builder for ESPResSo
David Beyer, Paola B. Torres, Sebastian P. Pineda +4
We present the Python-based Molecule Builder for ESPResSo (pyMBE), an open source software to design custom Coarse-Grained (CG) models, as well as pre-defined models of polyelectro…
Rheological Analysis and Evaluation of Measurement Techniques for the Curing Polymethylmethacrylate Bone Cement in Vertebroplasty
Zubin Trivedi, Jacek K. Wychowaniec, Dominic Gehweiler +6
Vertebroplasty is a minimally invasive surgical procedure used to treat vertebral fractures, which conventionally involves injecting polymethylmethacrylate (PMMA) bone cement into…
Structure of liquid--vapor interfaces: perspectives from liquid state theory, large-scale simulations, and potential grazing-incidence X-ray diffraction
Felix Höfling, Siegfried Dietrich
Grazing-incidence X-ray diffraction (GIXRD) is a scattering technique which allows one to characterize the structure of fluid interfaces down to the molecular scale, including the…
Motility-induced clustering of active particles under soft confinement
Timo Knippenberg, Ashreya Jayaram, Thomas Speck +1
We investigate the structural and dynamic properties of active Brownian particles (APs) confined within a soft annulus-shaped channel. Depending on the strength of the confinement…
Collective Hall current in chiral active fluids: Coupling of phase and mass transport through traveling bands
Frank Siebers, Robin Bebon, Ashreya Jayaram +1
Active fluids composed of constituents that are constantly driven away from thermal equilibrium can support spontaneous currents and can be engineered to have unconventional transp…
Colloidal Hard Spheres: Triumphs, Challenges and Mysteries
C. Patrick Royall, Patrick Charbonneau, Marjolein Dijkstra +4
The simplicity of hard spheres as a model system is deceptive. Although the particles interact solely through volume exclusion, that nevertheless suffices for a wealth of static an…
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…
