Chaotic properties of a turbulent isotropic fluid
By tracking the divergence of two initially close trajectories in phase space of forced turbulence,
the relation between the maximal Lyapunov exponent λ, and the Reynolds number Re is measured
using direct numerical ...
Granulation and suspension rheology: a unified treatment
Mixing a small amount of liquid into a powder can give rise to dry-looking granules; increasing the amount of liquid eventually produces a flowing suspension. We perform experiments on these phenomena using Spheriglass, ...
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 ...
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 ...

Quantum and isotope effects in lithium metal
The crystal structure of elements at zero pressure and temperature is the most fundamental information in condensed matter physics. For decades it has been believed that lithium, the simplest metallic element, has a ...
Pressure-induced localisation of the hydrogen-bond network in KOH-VI
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 ...
Infrared peak splitting from phonon localization in solid hydrogen
Dataset contain CASTEP input and output for calculations of localization of phonons in C2c hydrogen under pressure. Also contains codes written in the project to extend the lattice dynamics calculation to large disordered ...
Competing Timescales Lead to Oscillations in Shear-Thickening Suspensions
Competing timescales generate novelty. Here, we show that a coupling between the timescales imposed
by instrument inertia and the formation of interparticle frictional contacts in shear-thickening suspensions
leads to ...
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 ...
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 ...
Lid-driven cavity flow of viscoelastic liquids
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 ...
Linking particle properties to dense suspension extrusion flow characteristics using discrete element simulations
Extrusion is a widely used process for forming suspensions and pastes into designed shapes, and is central to the manufacture of many products. In this article, the extrusion through a square-entry die of non-Brownian ...
Probing the spatiotemporal dynamics of catalytic Janus particles with single-particle tracking and differential dynamic microscopy (Part 1)
Part 1 of datasets supporting the manuscript "Probing the spatiotemporal dynamics of catalytic Janus particles with single-particle tracking and differential dynamic microscopy". Abstract: We demonstrate differential dynamic ...
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 ...
Interacting Particles in 1D and 2D
Codes for Joshua Hellier's PhD thesis "On Interacting Particles in 1D and 2D" (Python). Related to https://arxiv.org/abs/1803.09712 .
Data for "Mixtures of blue phase liquid crystal with simple liquids: elastic emulsions and cubic fluid cylinders"
We numerically investigate the behavior of a phase-separating mixture of a blue phase I liquid crystal with an isotropic fluid. The resulting morphology is primarily controlled by an inverse capillary number, χ, setting ...
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 ...
Data and movies accompanying 'Kinetic theory of pattern formation in mixtures of microtubules and molecular motors'
In this study we formulate a theoretical approach, based on a Boltzmann-like kinetic equation, to describe pattern formation in two-dimensional mixtures of microtubular filaments and molecular motors. Following the previous ...
On the chain-melted phase of matter
Various single elements form incommensurate crystal structures under pressure, where a zeolite-type “host” sublattice surrounds a “guest” sublattice comprising 1D chains of atoms. On “chain melting,” diffraction peaks from ...
