Lane formation in driven colloidal mixtures: is it continuous or discontinuous? (2008)
Rex, Martin, Royall, C. Patrick, Van Blaaderen, Alfons, Löwen, Hartmut
Binary mixtures of oppositely charged colloids driven by an electric field are shown to exhibit a nonequilibrium transition towards lane formation if the driving force is increased. Brownian dynamics...
Direct observation of hydrodynamic instabilities in driven non-uniform colloidal dispersions (2008)
Wysocki, Adam, Royall, C. Patrick, Winkler, Roland G., Gompper, Gerhard, Tanaka, Hajime, Van Blaaderen, Alfons, ...
A Rayleigh-Taylor-like instability of a dense colloidal layer under gravity in a capillary of microfluidic dimensions is considered. We access all relevant lengthscales with particle-level microscopy...
Anisotropic colloids through non-trivial buckling (2008)
Quilliet, Catherine, Zoldesi, Carmen, Riera, Christophe, Van Blaaderen, Alfons, Imhof, Arnout
We present a study on buckling of colloidal particles, including experimental, theoretical and numerical developments. Oil-filled thin shells prepared by emulsion templating show buckling in mixtures...

Characterizing and tracking single colloidal particles with video holographic microscopy (2007)
Lee, Sang-Hyuk, Roichman, Yohai, Yi, Gi-Ra, Kim, Shin-Hyun, Yang, Seung-Man, Van Blaaderen, Alfons, ...
We use digital holographic microscopy and Mie scattering theory to simultaneously characterize and track individual colloidal particles. Each holographic snapshot provides enough information to...

Non-equilibrium sedimentation of colloids on the particle scale (2007)
Royall, C. Patrick, Dzubiella, Joachim, Schmidt, Matthias, Van Blaaderen, Alfons
We investigate sedimentation of model hard sphere-like colloidal dispersions confined in horizontal capillaries using laser scanning confocal microscopy, dynamical density functional theory, and...

Re-entrant melting and freezing in a model system of charged colloids (2005)
Royall, C. Patrick, Leunissen, Mirjam E., Hynninen, Antti-Pekka, Dijkstra, Marjolein, Van Blaaderen, Alfons
We studied the phase behavior of charged and sterically stabilized colloids using confocal microscopy in a less polar solvent (dielectric constant 5.4). Upon increasing the colloid volume fraction we...
Surface molecular view of colloidal gelation
Roke, Sylvie, Berg, Otto, Buitenhuis, Johan, Van Blaaderen, Alfons, Bonn, Mischa
We investigate the phase behavior of surface-functionalized silica colloids at both the molecular and macroscopic levels. This investigation allows us to relate collective properties such as...
Electrostatics at the oil–water interface, stability, and order in emulsions and colloids
Leunissen, Mirjam E., Van Blaaderen, Alfons, Hollingsworth, Andrew D., Sullivan, Matthew T., Chaikin, Paul M.
Oil–water mixtures are ubiquitous in nature and are particularly important in biology and industry. Usually additives are used to prevent the liquid droplets from coalescing. Here, we show that...
