• #### 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 ...
• #### Stability of Hydrogen Hydrates from Second-Order Møller-Plesset Perturbation Theory ﻿

The formation of gas hydrates and clathrates critically depends on the interaction between the host water network and the guest gas species. Density functional calculations can struggle to quantitatively capture these ...
• #### Stabilization of ammonia-rich hydrate inside icy planets ﻿

The interior structure of the giant ice planets Uranus and Neptune, but also of newly discovered exoplanets, is loosely constrained, because limited observational data can be satisfied with various interior models. Although ...
• #### Stacking characteristics of close packed materials ﻿

It is shown that the enthalpy of any close packed structure for a given element can be characterized as a linear expansion in a set of continuous variables α_n, which describe the stacking configuration. This enables us ...
• #### Structural and electronic properties of the alkali metal incommensurate phases ﻿

Under pressure, the alkali elements sodium, potassium, and rubidium adopt nonperiodic structures based on two incommensurate interpenetrating lattices. While all elements form the same “host” lattice, their “guest” lattices ...
• #### 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 ...
• #### SUPERSEDED - Interaction between Nearly Hard Colloidal Spheres at an Oil-Water Interface ﻿

## This dataset has been replaced by the one which can be found at https://doi.org/10.7488/ds/2848 . ## We show that the interaction potential between sterically stabilised, nearly hard-sphere (PMMA-PLMA) colloids at a ...
• #### Supplementary data for the manuscript "Quantitative modelling predicts the impact of DNA methylation on RNA polymerase II traffic" ﻿

Patterns of gene expression are primarily determined by proteins that locally enhance or repress transcription. While many transcription factors target a restricted number of genes, others appear to modulate transcription ...
• #### 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 ...
• #### Swimming suppresses correlations in dilute suspensions of pusher microorganisms ﻿

Active matter exhibits various forms of non-equilibrium states in the absence of external forcing, including macroscopic steady-state currents. Such states are often too complex to be modelled from first principles and our ...
• #### Testing the Wyart-Cates model for non-Brownian shear thickening using bidisperse suspensions [Dataset] ﻿

Raw simulation data and processed simulation and experimental data to support the article "Testing the Wyart-Cates model for non-Brownian shear thickening using bidisperse suspensions" by Ben M. Guy et al, published in ...
• #### Theory of high pressure hydrogen, made simple / AIRAPT 2015 data ﻿

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 ...
• #### 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 ...
• #### Tunable Shear Thickening in Suspensions ﻿

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 ...
• #### Turning a yield-stress calcite suspension into a shear-thickening one by tuning inter-particle friction ﻿

We show that a suspension of non-Brownian calcite particles in glycerol-water mixtures can be tuned continuously from being a yield-stress suspension to a shear-thickening suspension without a measurable yield stress by ...
• #### 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 ...
• #### Understanding high pressure molecular hydrogen with a hierarchical machine-learned potential ﻿

The hydrogen phase diagram has several unusual features which are well reproduced by density functional calculations. Unfortunately, these calculations do not provide good physical insights into why those features occur. ...
