Highpressure phase of brucite stable at Earth’s mantle transition zone and lower mantle conditions
We investigate the highpressure phase diagram of the hydrous mineral brucite, Mg(OH)2, using structure search algorithms and ab initio simulations. We predict a new highpressure phase stable at pressure and temperature ... 
Highpressure phase transitions in rubidium and caesium hydroxides
A computational investigation of the highpressure phase sequence of the heaviest alkali hydroxides, RbOH and CsOH, shows that the phase diagram of both compounds is richer than hitherto thought. Firstprinciples calculations ... 
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 ... 
Liddriven cavity flow of viscoelastic liquids
The liddriven cavity flow is a wellknown benchmark problem for the validation of new numerical methods and techniques. In experimental and numerical studies with viscoelastic fluids in such liddriven flows, purelyelastic ... 
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 ... 
Particlesize 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 ... 
A Phenomenological Description of BslA Assemblies Across Multiple Length Scales
Intrinsically interfacially active proteins have garnered considerable interest recently due to their potential use in a range of materials applications. Notably, the fungal hydrophobins are known to form robust and well ... 
Predicting the threedimensional folding of cisregulatory regions in mammalian genomes using bioinformatic data and polymer models
The threedimensional organisation of chromosomes can be probed using methods such as CaptureC. However it is unclear how such population level data relates to the organisation within a single cell, and the mechanisms ... 
Pressureinduced localisation of the hydrogenbond network in KOHVI
Using a combination of ab initio crystal structure prediction and neutron diffraction techniques, we have solved the full structure of KOHVI at 7 GPa. Rather than being orthorhombic and protonordered as had previously ... 
Quantitative morphological characterization of bicontinuous Pickering emulsions via interfacial curvatures
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 ... 
Selforganization and transition to turbulence in isotropic fluid motion driven by negative damping at low wavenumbers
We observe a symmetrybreaking transition from a turbulent to a selforganized state in direct numerical simulation of the NavierStokes equation at very low Reynolds number. In this selforganised state the kinetic energy ... 
Shear thickening regimes of dense nonBrownian suspensions
The images are the raw figures used to produce the plots in the paper entitled: “Shear thickening regimes of dense nonBrownian 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 emulsionfilled protein gels’, in which fat droplets are chemicallybonded ... 
Sudden relaminarisation and lifetimes in forced isotropic turbulence
We demonstrate an unexpected connection between isotropic turbulence and wallbounded 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 twodimensional colloidal crystal. The Janus particles orbit individual colloids and hop between colloids stochastically, with a hopping rate ... 
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 exchangecorrelation. We present code for a simple ... 
Towards a unified description of the rheology of hardparticle 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 ... 
Twoscale evolution during shear reversal in dense suspensions
