Ionic effects in self-propelled Pt-coated Janus swimmers
A. T. Brown, W. C. K Poon
Colloidal particles partially coated with platinum and dispersed in H2O2 solution are often used as model self-propelled colloids. Most current data suggest that neutral self-diffu…
On polydispersity and the hard-sphere glass transition
Emanuela Zaccarelli, Siobhan M. Liddle, Wilson C. K. Poon
We simulate the dynamics of polydisperse hard spheres at high packing fractions, , with an experimentally-realistic particle size distribution (PSD) and other commonly-used PSDs…
Enhanced diffusion of nonswimmers in a three-dimensional bath of motile bacteria
A. Jepson, V. A. Martinez, J. Schwarz-Linek +2
We show, using differential dynamic microscopy, that the diffusivity of non-motile cells in a three-dimensional (3D) population of motile E. coli is enhanced by an amount proportio…
From Clarkia to Escherichia and Janus: the physics of natural and synthetic active colloids
W C K Poon
An active colloid is a suspension of particles that transduce free energy from their environment and use the energy to engage in intrinsically non-equilibrium activities such as gr…
Effects of the Carnahan-Starling free energy within theories of fluids with short-range attraction
John J. Williamson, R. Mike L. Evans, Wilson C. K. Poon +1
Within the Free-Volume Asakura-Oosawa-Vrij (FVAO) theory of colloid-polymer mixtures, we show that unphysical gas-liquid binodals predicted in the regime of small attraction range…
