ARCHER National Supercomputing Service SP Quarterly Report for Q4 2014 and associated dataset
• Escherichia coli as a model active colloid: A practical introduction ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ﻿

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 ...
