Slip length dependent propulsion speed of catalytic colloidal swimmers near walls

Stefania Ketzetzi, Joost de Graaf, Rachel P. Doherty +1

Catalytic colloidal swimmers that propel due to self-generated fluid flows exhibit strong affinity for surfaces. We here report experimental measurements of significantly different…

ESPResSo 4.0 -- An Extensible Software Package for Simulating Soft Matter Systems

Florian Weik, Rudolf Weeber, Kai Szuttor +7

ESPResSo 4.0 is an extensible simulation package for research on soft matter. This versatile molecular dynamics program was originally developed for coarse-grained simulations of c…

Supramolecular copolymers predominated by alternating order: theory and application

Reinier van Buel, Daniel Spitzer, Paul van der Schoot +2

We investigate the copolymerization behavior of a two-component system into quasi-linear self-assemblies under conditions that interspecies binding is favored over identical specie…

Learning heterogenous reaction rates from stochastic simulations

Ariana Torres-Knoop, Ivan Kryven

Reaction rate equations are ordinary differential equations that are frequently used to describe deterministic chemical kinetics at the macroscopic scale. At the microscopic scale,…

Dynamic Stern layers in charge-regulating electrokinetic systems: three regimes from an analytical approach

B. L. Werkhoven, S. Samin, René van Roij

We present analytical solutions for the electrokinetics at a charged surface with both non-zero Stern-layer conductance and finite chemical reaction rates. We have recently studied…

Hydrodynamics strongly affect the dynamics of colloidal gelation but not gel structure

Joost de Graaf, Wilson C. K. Poon, Magnus J. Haughey +1

Colloidal particles with strong, short-ranged attractions can form a gel. We simulate this process without and with hydrodynamic interactions (HI), using the lattice-Boltzmann meth…

A macroscopic model for sessile droplet evaporation on a flat surface

Thijs W. G. van der Heijden, Anton A. Darhuber, Paul van der Schoot

The evaporation of sessile droplets on a flat surface involves a complex interplay between phase change, diffusion, advection and surface forces. In an attempt to significantly red…

Unravelling structural rearrangement of polymer colloidal crystals under dry sintering conditions

Alexey V. Zozulya, Ivan A. Zaluzhnyy, Nastasia Mukharamova +7

Structural rearrangement of polystyrene colloidal crystals under dry sintering conditions has been revealed by in situ grazing incidence X-ray scattering. Measured diffraction patt…

Ratchet-induced variations in bulk states of an active ideal gas

Jeroen Rodenburg, Siddharth Paliwal, Marjolein de Jager +3

We study the distribution of active, noninteracting particles over two bulk states separated by a ratchet potential. By solving the steady-state Smoluchowski equations in a flux-fr…

The effect of flexibility and bend angle on the phase diagram of hard colloidal boomerangs

Tara Drwenski, René van Roij

We study the effect of flexibility and bend angle on systems of hard semiflexible boomerangs. These are modelled as two rodlike segments joined at one end with an angle that can fl…

Flow-induced surface charge heterogeneity in electrokinetics due to Stern-layer conductance coupled to reaction kinetics

B. L. Werkhoven, J. C. Everts, S. Samin +1

We theoretically study the electrokinetic problem of a pressure-induced liquid flow through a narrow long channel with charged walls, going beyond the classical Helmholtz-Schmoluko…

Depletion-driven four-phase coexistences in discotic systems

Álvaro González García, Remco Tuinier, Jasper V. Maring +3

Free volume theory (FVT) is a versatile and tractable framework to predict the phase behaviour of mixtures of platelets and non-adsorbing polymer chains in a common solvent. Within…

Connectedness percolation of hard convex polygonal rods and platelets

Tara Drwenski, René van Roij, Paul van der Schoot

The properties of polymer composites with nanofiller particles change drastically above a critical filler density known as the percolation threshold. Real nanofillers, such as grap…

Anomalous system-size dependence of electrolytic cells with an electrified oil-water interface

Marise J. E. Westbroek, Niels Boon, René van Roij

Manipulation of the charge of the dielectric interface between two bulk liquids not only enables the adjustment of the interfacial tension but also controls the storage capacity of…

Hard competition: stabilizing the elusive biaxial nematic phase in suspensions of colloidal particles with extreme lengths

Simone Dussi, Nikos Tasios, Tara Drwenski +2

We use computer simulations to study the existence and stability of a biaxial nematic phase in systems of hard polyhedral cuboids, triangular prisms, and rhombic platelets, c…

Continuum Percolation of Polydisperse Rods in Quadrupole Fields: Theory and Simulations

Shari P. Finner, Mihail I. Kotsev, Mark A. Miller +1

We investigate percolation in mixtures of nanorods in the presence of external fields that align or disalign the particles with the field axis. Such conditions are found in the for…
