Hypothesis: Diffusion in confinement is an important fundamental problem with significant implications for applications of supported liquid phases. However, resolving the spatially…
Modelling diffusive transport of particles interacting with slit nanopore walls: The case of fullerenes in toluene filled alumina pores
Andreas Baer, Paolo Malgaretti, Malte Kaspereit +2
Accurate modeling of diffusive transport of nanoparticles across nanopores is a particularly challenging problem. The reason is that for such narrow pores the large surface-to-volu…
Hydrodynamic particle interactions in linear and radial viscosity gradients
Sebastian Ziegler, Ana-Sunčana Smith
We present a versatile perturbative calculation scheme to determine the mobility matrix for two and more particles in a low Reynolds number fluid with spatially variant viscosity.…
Crowding competes with trapping to enhance interfacial diffusion
Mislav Cvitković, Dipanwita Ghanti, Niklas Raake +1
Diffusion in the crowded environments of the biological membranes or materials interfaces often involves intermittent binding to surface proteins or defects. To account for this si…
Regimes of motion of magnetocapillary swimmers
Alexander Sukhov, Maxime Hubert, Galien Grosjean +6
The dynamics of a triangular magnetocapillary swimmer is studied using the lattice Boltzmann method. Performing extensive numerical simulations taking into account the coupled dyna…
Recent Advances and Prospects in the Research of Nascent Adhesions
Henning Stumpf, Andreja Ambriović-Ristov, Aleksandra Radenovic +1
Nascent adhesions are submicron transient structures promoting the early adhesion of cells to the extracellular matrix. Nascent adhesions typically consist of several tens of integ…
A general perturbative approach for bead-based microswimmers reveals rich self-propulsion phenomena
Sebastian Ziegler, Maxime Hubert, Nicolas Vandewalle +2
Studies of model microswimmers have significantly contributed to the understanding of the principles of self-propulsion we have today. However, only a small number of microswimmer…
Capillary assemblies in a rotating magnetic field
Galien Grosjean, Maxime Hubert, Ylona Collard +4
Small objects floating on a fluid have a tendency to aggregate due to capillary forces. This effect has been used, with the help of a magnetic induction field, to assemble submilli…
Geometric effects in random assemblies of ellipses
Jakov Lovrić, Sara Kaliman, Wolfram Barfuß +2
Assemblies of anisotropic particles commonly appear in studies of active many-body systems. However, in two dimensions, the geometric ramifications of the finite density of such ob…

The most prominent defence of the unicellular parasite Trypanosoma brucei against the host immune system is a dense coat that comprises a variant surface glycoprotein (VSG). Despit…
Catalytic flow with a coupled Finite Difference -- Lattice Boltzmann scheme
Nadiia Kulyk, Daniel Berger, Ana-Sunčana Smith +1
Many catalyst devices employ flow through porous structures, which leads to a complex macroscopic mass and heat transport. To unravel the detailed dynamics of the reactive gas flow…
Effect of body deformability on microswimming

In this work we consider the following question: given a mechanical microswimming mechanism, does increased deformability of the swimmer body hinder or promote the motility of the…
Microswimming with inertia
Jayant Pande, Kristina Pickl, Oleg Trosman +2
Microswimmers, especially in theoretical treatments, are generally taken to be completely inertia-free, since inertial effects on their motion are typically small and assuming thei…
