• BslA-stabilised emulsion droplets with designed microstructure 

    Bromley, Keith Matthew; MacPhee, Cait
    Original microscope images of BslA-stabilised emulsion droplets and two time-lapse confocal microscope sequences (available to view using ImageJ imaging software) of BslA-stabilised partially coalesced droplets melting in ...
  • DATA: Unsteady flow and particle migration in dense, non-Brownian suspensions 

    Hermes, Michiel
    We present experimental results on dense corn-starch suspensions as examples of non-Brownian, nearly-hard particles that undergo continuous and discontinuous shear thickening (CST and DST) at intermediate and high densities ...
  • Escherichia coli as a model active colloid: A practical introduction 

    Schwarz-Linek, Jana; Arlt, Jochen; Jepson, Alys; Dawson, Angela; Vissers, Teun; Miroli, Dario; Pilizota, Teuta; Martinez, Vincent A.; Poon, Wilson C. K.
    The flagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between different laboratories, reproducible protocols ...
  • Gravitational collapse of depletion-induced colloidal gels 

    Harich, R.; Blythe, T.W.; Hermes, M.; Zaccarelli, E.; Sederman, A.J.; Gladden, L.F.; Poon, W.C.K.
    We study the ageing and ultimate gravitational collapse of colloidal gels in which the interparticle attraction is induced by non-adsorbing polymers via the depletion effect. The gels are formed through arrested spinodal ...
  • Hydrodynamic and Contact Contributions to Continuous Shear Thickening in Colloidal Suspensions 

    Lin, Neil; Guy, Ben Michael; Hermes, Michiel; Ness, Christopher; Sun, Jin; Poon, Wilson C. K.; Cohen, Itai
    Shear thickening is a widespread phenomenon in suspension flow that, despite sustained study, is still the subject of much debate. The longstanding view that shear thickening is due to hydrodynamic clusters has been ...
  • Interfacial rheology of sterically stabilized colloids at liquid interfaces and its effect on the stability of Pickering emulsions 

    Van Hooghten, Rob; Blair, Victoria; Vananroye, Anja; Schofield, Andrew; Vermant, Jan; Thijssen, Job
    Particle-laden interfaces can be used to stabilize a variety of high-interface systems, from foams over emulsions to polymer blends. The relation between the particle interactions, the structure and rheology of the interface, ...
  • Particle-size effects in the formation of bicontinuous Pickering emulsions 

    Reeves, M.; Brown, A. T.; Schofield, A. B.; Cates, M. E.; Thijssen, J. H. J.
    We demonstrate that the formation of bicontinuous emulsions stabilized by interfacial particles (bijels) is more robust when nanoparticles rather than microparticles are used. Emulsification via spinodal demixing in the ...
  • Quantitative morphological characterization of bicontinuous Pickering emulsions via interfacial curvatures 

    Reeves, Matthew; Stratford, Kevin; Thijssen, Job
    Bicontinuous Pickering emulsions (bijels) are a physically interesting class of soft materials with many potential applications including catalysis, microfluidics and tissue engineering. They are created by arresting the ...
  • Shear thickening regimes of dense non-Brownian suspensions 

    Ness, Christopher; Sun, Jin
    The images are the raw figures used to produce the plots in the paper entitled: “Shear thickening regimes of dense non-Brownian suspensions” with DOI:10.1039/C5SM02326B published in the Journal “Soft Matter” by the Royal ...
  • Simplicity in complexity – towards a soft matter physics of caramel 

    Weir, Simon
    Caramel is a mixture of sugars, milk proteins, fat and water cooked at high temperatures to initiate Maillard reactions. We study caramels as ‘active emulsion-filled protein gels’, in which fat droplets are chemically-bonded ...
  • Swimming In a Crystal 

    Brown, Aidan T.; Vladescu, Ioana D.; Dawson, Angela; Vissers, Teun; Schwarz-Linek, Jana; Lintuvuori, Juho S.; Poon, Wilson C. K.
    We study catalytic Janus particles and Escherichia coli bacteria swimming in a two-dimensional colloidal crystal. The Janus particles orbit individual colloids and hop between colloids stochastically, with a hopping rate ...
  • Towards a unified description of the rheology of hard-particle suspensions 

    Guy, B. M.; Hermes, M.; Poon, W. C. K.
    The rheology of suspensions of Brownian, or colloidal, particles (diameter~$d \lesssim 1~\mu$m) differs markedly from that of larger grains ($d \gtrsim 50~\mu$m). Each of these two regimes has been separately studied, but ...
  • Tunable Shear Thickening in Suspensions 

    Lin, Neil; Ness, Christopher; Cates, Mike; Sun, Jin; Cohen, Itai
    Shear thickening, an increase of viscosity with shear rate, is a ubiquitous phenomena in suspended materials that has implications for broad technological applications. Controlling this thickening behavior remains a major ...
  • Two-scale evolution during shear reversal in dense suspensions 

    Ness, Christopher; Sun, Jin
    Matlab data files used to plot the figures in a paper titled "Two-scale evolution during shear reversal in dense suspensions".
