Active Janus colloids at chemically structured surfaces
Uspal, W.E.; Popescu, Mihail N.; Dietrich, Siegfried; Tasinkevych, M. (American Institute of Physics, 2019)If catalytically active Janus particles are dispersed in certain liquid solutions, they can create a gradient in the ...

Confinement effects on diffusiophoretic self-propellers
Popescu, Mihail N.; Dietrich, Siegfried; Oshanin, G. (American Institute of Physics, 2009)We study theoretically the effects of spatial confinement on the phoretic motion of a dissolved particle driven by composition ...

Effective Interaction between Active Colloids and Fluid Interfaces Induced by Marangoni Flows
Domínguez Álvarez, Álvaro; Malgaretti, Paolo; Popescu, Mihail N.; Dietrich, Siegfried (American Physical Society, 2016-02-28)We show theoretically that near a fluid-fluid interface a single active colloidal particle generating, e.g., chemicals or ...

Force balance of particles trapped at fluid interfaces
Domínguez Álvarez, Álvaro; Oettel, Martin; Dietrich, Siegfried (AIP Publishing, 2008-03)flat configuration. We apply this analogy in order to compute the asymptotic decay of the effective force between particles ...

Interface-mediated spontaneous symmetry breaking and mutual communication between drops containing chemically active particles
Singh, D. P.; Domínguez Muñoz, Antonio Damián; Choudhury, U.; Kottapalli, S. N.; Popescu, Mihail N.; Dietrich, Siegfried; Fischer, P. (Nature Research, 2020)Symmetry breaking and the emergence of self-organized patterns is the hallmark of complexity. Here, we demonstrate that a ...

Shock waves in capillary collapse of colloids: A model system for two-dimensional screened Newtonian gravity
Bleibel, J.; Dietrich, Siegfried; Domínguez Álvarez, Álvaro; Oettel, Martin (American Physical Society, 2011-09-16)Using Brownian dynamics simulations, density functional theory, and analytical perturbation theory we study the collapse ...

Theory of capillary-induced interactions beyond the superposition approximation
Domínguez Álvarez, Álvaro; Oettel, Martin; Dietrich, Siegfried (AIP Publishing, 2007-11)Within a general theoretical framework, we study the effective, deformation-induced interaction between two colloidal ...
