Polymorph Selection in Charged Colloids in the Second Nucleation Step
C. Patrick Royall
We study polymorph selection in a model of charged colloids, with a focus on the higher-order structure prior to and during nucleation. Specifically, we carry out molecular dynamic…
Colloidoscope: Detecting Dense Colloids in 3d with Deep Learning
Abdelwahab Kawafi, Lars Kürten, Levke Ortlieb +4
Colloidoscope is a deep learning pipeline employing a 3D residual Unet architecture, designed to enhance the tracking of dense colloidal suspensions through confocal microscopy. Th…
Yielding in colloidal gels: from local structure to meso-scale strand breakage and macroscopic failure
Himangsu Bhaumik, Tanniemola B. Liverpool, C. Patrick Royall +1
We study creep flow and yielding of particulate depletion gels under constant shear stress, combining data on different length and time scales. We characterise the breakage of meso…
Identification and classification of clusters of dipolar colloids in an external field
Katherine Skipper, Fergus J. Moore, C. Patrick Royall
Colloids can acquire a dipolar interaction in the presence of an external electric field. At high field strength, the particles form strings in the field direction. However at weak…
Dominating Lengthscales of Zebrafish Collective Behaviour
Yushi Yang, Francesco Turci, Erika Kague +3
Collective behaviour in living systems is observed across many scales, from bacteria to insects, to fish shoals. Zebrafish have emerged as a model system amenable to laboratory stu…
Traveling strings of active dipolar colloids
Xichen Chao, Katherine Skipper, C. Patrick Royall +2
We study an intriguing new type of self-assembled active colloidal polymer system in 3D. It is obtained from a suspension of Janus particles in an electric field that induces paral…
Colloidal Hard Spheres: Triumphs, Challenges and Mysteries
C. Patrick Royall, Patrick Charbonneau, Marjolein Dijkstra +4
The simplicity of hard spheres as a model system is deceptive. Although the particles interact solely through volume exclusion, that nevertheless suffices for a wealth of static an…
Active Brownian Particles in Random and Porous Environments
Fergus J. Moore, John Russo Tanniemola B. Liverpool, C. Patrick Royall
The transport of active particles may occur in complex environments, in which it emerges from the interplay between the mobility of the active components and the quenched disorder…
Necking and failure of a colloidal gel arm: signatures of yielding on different length scales
Kristian Thijssen, T. B. Liverpool, C. Patrick Royall +1
Colloidal gels consist of percolating networks of interconnected arms. Their mechanical properties depend on the individual arms, and on their collective behaviour. We use numerica…
Biases in Inverse Ising Estimates of Near-Critical Behaviour
Maximilian Benedikt Kloucek, Thomas Machon, Shogo Kajimura +3
Inverse Ising inference allows pairwise interactions of complex binary systems to be reconstructed from empirical correlations. Typical estimators used for this inference, such as…
The rheology of confined colloidal hard discs
Ian Williams, Erdal C. Oğuz, Hartmut Löwen +2
Colloids may be treated as `big atoms' so that they are good models for atomic and molecular systems. Colloidal hard disks are therefore good models for 2d materials and although t…
Direct Imaging of Contacts and Forces in Colloidal Gels
Jun Dong, Francesco Turci, Robert L. Jack +2
Colloidal dispersions are prized as model systems to understand basic properties of materials, and are central to a wide range of industries from cosmetics to foods to agrichemical…
Dynamics and Interactions of Quincke Roller Clusters: from Orbits and Flips to Excited States
Abraham Mauleon-Amieva, Michael P. Allen, C. Patrick Royall
Active matter systems may be characterised by the conversion of energy into active motion, e.g. the self-propulsion of microorganisms. Artificial active colloids form models which…
Real Space Analysis of Colloidal Gels: Triumphs, Challenges and Future Directions
C. Patrick Royall, Malcolm A. Faers, Sian L. Fussell +1
Colloidal gels constitute an important class of materials found in many contexts and with a wide range of applications. Yet as matter far from equilibrium, gels exhibit a variety o…
Isomorphs in nanoconfined liquids
Benjamin M. G. D. Carter, C. Patrick Royall, Jeppe C. Dyre +1
We study in this paper the possible existence of Roskilde-simple liquids and their isomorphs in a rough-wall nanoconfinement. Isomorphs are curves in the thermodynamic phase diagra…
Flexible confinement leads to multiple relaxation regimes in glassy colloidal liquids
Ian Williams, Erdal C. Oğuz, Paul Bartlettl +2
Understanding relaxation of supercooled fluids is a major challenge and confining such systems can lead to bewildering behaviour. Here we exploit an optically confined colloidal mo…
Efficacy of face coverings in reducing transmission of COVID-19: calculations based on models of droplet capture
Joshua F. Robinson, Ioatzin Rios de Anda, Fergus J. Moore +3
In the COVID--19 pandemic, among the more controversial issues is the use of masks and face coverings. Much of the concern boils down to the question -- just how effective are face…
Decorated Protein Networks: Functional Nanomaterials with Tunable Domain Size
Ioatzin Rıos de Anda, Angelique Coutable-Pennarun, Chris Brasnett +5
The implementation of natural and artificial proteins with designer properties and functionalities offers unparalleled opportunity for functional nanoarchitectures formed through s…
Morphological thermodynamics for hard bodies from a controlled expansion
Joshua F. Robinson, Roland Roth, C. Patrick Royall
The morphometric approach is a powerful ansatz for decomposing the chemical potential for a complex solute into purely geometrical terms. This method has proven accuracy in hard sp…
Anisotropic viscoelastic phase separation in polydisperse hard rods: non-sticky gelation
Claudia Ferreiro-Córdova, C. Patrick Royall, Jeroen S. van Duijneveldt
Spinodal demixing of systems into two phases having very different viscosities leads to viscoelastic networks, i.e. gels. Here we consider demixing in a colloidal system where one…
Transmission of torque at the nanoscale
Ian Williams, Erdal C. Oğuz, Thomas Speck +3
In macroscopic mechanical devices torque is transmitted through gearwheels and clutches. In the construction of devices at the nanoscale, torque and its transmission through soft m…
Long-Lived Non-Equilibrium Interstitial-Solid-Solutions in Binary Mixtures
I. Ríos de Anda, F. Turci, R. Sear +1
We perform particle resolved experimental studies on the heterogeneous crystallisation process of two compo- nent mixtures of hard spheres. The components have a size ratio of 0.39…
Locally favoured structures and dynamic length scales in a simple glass-former
C. Patrick Royall, Walter Kob
We investigate the static and dynamic properties of a weakly polydisperse hard sphere system in the deeply supercooled state, i.e. at densities higher than that corresponding to th…
Surface melting and crystallisation driven by sedimentation: a particle resolved study
Francesco Turci, C. Patrick Royall
We investigate the effects of the reversal of the gravitational field onto a sedimented and partially crystallised suspension of nearly-hard sphere colloids. We analyse the structu…
