    • Towards a unified description of the rheology of hard-particle suspensions 

      Guy, BM; Hermes, M; Poon, Wilson CK
      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 ...
    • 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 CK
      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 ...
    • Particle-size effects in the formation of bicontinuous Pickering emulsions 

      Reeves, M; Brown, Aidan T; Schofield, AB; Cates, Mike E; Thijssen, Job
      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 ...
    • Sudden relaminarisation and lifetimes in forced isotropic turbulence 

      Linkmann, Moritz F; 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 CK
      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 ...
    • Gravitational collapse of depletion-induced colloidal gels 

      Harich, R; Blythe, TW; Hermes, Michiel; Zaccarelli, E; Sederman, AJ; Gladden, LF; Poon, Wilson CK
      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 ...
    • 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 ...
    • 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 ...
    • Hydrodynamic and Contact Contributions to Continuous Shear Thickening in Colloidal Suspensions 

      Lin, Neil; Guy, Ben Michael; Hermes, Michiel; Ness, Christopher; Sun, Jin; Poon, Wilson CK; 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 ...
    • 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".
    • Theory of high pressure hydrogen, made simple / AIRAPT 2015 data 

      Magdau, Ioan; Ackland, Graeme J
      We report molecular dynamics calculations for Phase I of hydrogen which show that all the phase transitions can be understood in a classical model with simple treatment of exchange-correlation. We present code for a simple ...
    • Computational phase diagrams of noble gas hydrates under pressure 

      Hermann, Andreas
      We present results from a first-principles study on the stability of noble gas-water compounds in the pressure range 0-100 kbar. Filled-ice structures based on the host water networks ice-Ih, ice-Ic, ice-II, and C0 interacting ...
    • Pressure-induced localisation of the hydrogen-bond network in KOH-VI 

      Hermann, Andreas
      Using a combination of ab initio crystal structure prediction and neutron diffraction techniques, we have solved the full structure of KOH-VI at 7 GPa. Rather than being orthorhombic and proton-ordered as had previously ...
    • Predicting the three-dimensional folding of cis-regulatory regions in mammalian genomes using bioinformatic data and polymer models 

      Brackley, Chris A; Brown, Jill M; Waithe, Dominic; Babbs, Christian; Davies, James; Hughes, Jim R; Buckle, Veronica J; Marenduzzo, Davide
      The three-dimensional organisation of chromosomes can be probed using methods such as Capture-C. However it is unclear how such population level data relates to the organisation within a single cell, and the mechanisms ...
    • What is the ‘minimum inhibitory concentration’ (MIC) of pexiganan acting on Escherichia coli? - A cautionary case study 

      Jepson, Alys; Schwarz-Linek, Jana; Ryan, Lloyd; Ryadnov, Maxim; Poon, Wilson CK
      We measured the minimum inhibitory concentration (MIC) of the antimicrobial peptide pexiganan acting on Escherichia coli, and report an intrinsic variability in such measurements. These results led to a detailed study of ...

      Poole, RJ; Sousa, RG; Afonso, A; Pinho, FT; Oliveira, PJ; Morozov, Alexander N; Alves, MA
      The lid-driven cavity flow is a well-known benchmark problem for the validation of new numerical methods and techniques. In experimental and numerical studies with viscoelastic fluids in such lid-driven flows, purely-elastic ...
    • A 1-dimensional statistical mechanics model for nucleosome positioning on genomic DNA 

      Tesoro, S; Ali, I; Morozov, Alexander N; Sulaiman, N; Marenduzzo, Davide
      The first level of folding of DNA in eukaryotes is provided by the so-called “10-nm chromatin fibre”, where DNA wraps around histone proteins (∼10 nm in size) to form nucleosomes, which go on to create a zig-zagging ...
