Direct observation of dynamical heterogeneities in colloidal hard-sphere suspensions

WK Kegel, A van Blaaderen - Science, 2000 - science.org
The real-space dynamics in a model system of colloidal hard spheres was studied by means
of time-resolved fluorescence confocal scanning microscopy. Direct experimental evidence …

Surface roughness directed self-assembly of patchy particles into colloidal micelles

DJ Kraft, R Ni, F Smallenburg… - Proceedings of the …, 2012 - National Acad Sciences
Colloidal particles with site-specific directional interactions, so called “patchy particles”, are
promising candidates for bottom-up assembly routes towards complex structures with …

Anomalously large equilibrium clusters of colloids

J Groenewold, WK Kegel - The Journal of Physical Chemistry B, 2001 - ACS Publications
We propose a mechanism for mesophase separation in a system of aggregating colloids.
Conditions are outlined under which colloids can form equilibrium clusters with very large sizes…

Thermodynamically stable pickering emulsions

S Sacanna, WK Kegel, AP Philipse - Physical review letters, 2007 - APS
We show that under appropriate conditions, mixtures of oil, water, and nanoparticles form
thermodynamically stable oil-in-water emulsions with monodisperse droplet diameters in the …

Preparation of monodisperse, fluorescent PMMA–latex colloids by dispersion polymerization

G Bosma, C Pathmamanoharan, EHA De Hoog… - Journal of Colloid and …, 2002 - Elsevier
We report a single step procedure to prepare monodisperse colloidal poly(methyl)methacrylate
(PMMA) particles where fluorescent dyes are incorporated into the polymer network. The …

Understanding the self-assembly of charged nanoparticles at the water/oil interface

F Reincke, WK Kegel, H Zhang, M Nolte… - Physical Chemistry …, 2006 - pubs.rsc.org
We present a thermodynamic evaluation of the self-assembly of charged nanometer-sized
particles at the water/oil interface. The chemical potentials of the nanoparticles in the bulk (…

Self-assembly of colloids with liquid protrusions

DJ Kraft, WS Vlug, CM van Kats… - Journal of the …, 2009 - ACS Publications
A facile and flexible synthesis for colloidal molecules with well-controlled shape and tunable
patchiness is presented. Cross-linked polystyrene spheres with a liquid protrusion were …

Quantitative real-space analysis of self-assembled structures of magnetic dipolar colloids

M Klokkenburg, RPA Dullens, WK Kegel, BH Erné… - Physical review …, 2006 - APS
We present the first real-space analysis on a single-particle level of the dipolar chains and
branched clusters self-assembling in magnetic fluids in zero field. Spatial correlations and …

[HTML][HTML] Competing hydrophobic and screened-Coulomb interactions in hepatitis B virus capsid assembly

WK Kegel, P van der Schoot - Biophysical journal, 2004 - cell.com
Recent experiments show that, in the range from ∼15 to 45C, an increase in the temperature
promotes the spontaneous assembly into capsids of the Escherichia coli-expressed coat …

Colloidal molecules with well-controlled bond angles

DJ Kraft, J Groenewold, WK Kegel - Soft Matter, 2009 - pubs.rsc.org
We present a straightforward technique for the synthesis of asymmetric colloidal molecules
with uniform and well-controlled bond angles. The new method makes use of coalescence of …
