  • 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 gel states in hard-sphere-like colloids in which an interparticle depletion attraction has been induced by non-adsorbing polymers. Visual observations show that ...
  • 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 ...
  • Nonuniversality and finite dissipation in magnetohydrodynamic turbulence 

    Linkmann, Moritz F.; Berera, Arjun; McComb, W. David; McKay, Mairi E.
    This dataset contains the results of the study discussed in the paper 'Nonuniversality and finite dissipation in decaying magnetohydrodynamic turbulence': "A model equation for the Reynolds number dependence of the ...
  • 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 ...
  • Self-organization and transition to turbulence in isotropic fluid motion driven by negative damping at low wavenumbers 

    McComb, W. David; Linkmann, Moritz F.; Berera, Arjun; Yoffe, Samuel R.; Jankauskas, Bernardas
    We observe a symmetry-breaking transition from a turbulent to a self-organized state in direct numerical simulation of the Navier-Stokes equation at very low Reynolds number. In this self-organised state the kinetic energy ...
  • 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 ...
  • Sudden relaminarisation and lifetimes in forced isotropic turbulence 

    Linkmann, Moritz; Morozov, Alexander
    We demonstrate an unexpected connection between isotropic turbulence and wall-bounded shear flows. We perform direct numerical simulations of isotropic turbulence forced at large scales at moderate Reynolds numbers and ...
  • 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 ...
  • 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".
  • UK Research Software Survey 2014 

    Hettrick, Simon; Antonioletti, Mario; Carr, Les; Chue Hong, Neil; Crouch, Stephen; De Roure, David; Emsley, Iain; Goble, Carole; Hay, Alexander; Inupakutika, Devasena; Jackson, Mike; Nenadic, Aleksandra; Parkinson, Tim; Parsons, Mark I; Pawlik, Aleksandra; Peru, Giacomo; Proeme, Arno; Robinson, John; Sufi, Shoaib
    This spreadsheet contains the anonymised data collected as part of a survey of UK researchers in their use of research software. We asked people specifically about “research software” which we defined as: “Software ...
