Guiding catalytically active particles with chemically patterned surfaces
W. E. Uspal, M. N. Popescu, S. Dietrich +1
Catalytically active Janus particles suspended in solution create gradients in the chemical composition of the solution along their surfaces, as well as along any nearby container…
Topographical pathways guide chemical microswimmers
Juliane Simmchen, Jaideep Katuri, William E. Uspal +3
Achieving control over the directionality of active colloids is essential for their use in practical applications such as cargo carriers in microfluidic devices. So far, guidance o…
Self-propulsion of a catalytically active particle near a planar wall: from reflection to sliding and hovering
W. E. Uspal, M. N. Popescu, S. Dietrich +1
Micron-sized particles moving through solution in response to self-generated chemical gradients serve as model systems for studying active matter. Their far-reaching potential appl…
Diffusion-limited deposition with dipolar interactions: fractal dimension and multifractal structure
M. Tasinkevych, J. M. Tavares, F. de los Santos
Computer simulations are used to generate two-dimensional diffusion-limited deposits of dipoles. The structure of these deposits is analyzed by measuring some global quantities: th…
Diffusion-limited deposition of dipolar particles
F. de los Santos, J. M. Tavares, M. Tasinkevych +1
Deposits of dipolar particles are investigated by means of extensive Monte Carlo simulations. We found that the effect of the interactions is described by an initial, non-universal…
Deposition of magnetic particles: A computer simulation study
F. de los Santos, M. Tasinkevych, J. M. Tavares +1
We report a Monte Carlo simulation of deposition of magnetic particles on a one-dimensional substrate. Incoming particles interact with those that are already part of the deposit v…
