Our papers are the official record of our discoveries. They allow others to build on and apply our work. Each paper is the result of many months of research, so we make a special effort to make them clear, beautiful and inspirational, and publish them in leading journals.

  • Reconstructing grain-shape statistics from electron back-scatter diffraction microscopy

    RFR. FarrZVMHEG Physical Review Materials

    Grain shape inference

    The distributions of size and shape of a material’s grains can be constructed from a 2D slice of the material and electron diffraction data.

  • Mean grain diameters from thin sections: matching the average to the problem

    RFR. FarrVHMH Mineralogical Magazine

    3d grains from 2d slices

    Moment-based methods provide a simple way to describe a population of spherical particles and extract 3d information from 2d measurements.

  • Simple heuristic for the viscosity of polydisperse hard spheres

    RFR. Farr Journal of Chemical Physics

    Viscosity of polydisperse spheres

    A quick and simple way to evaluate the packing fraction of polydisperse spheres, which is a measure of how they crowd around each other.

  • Random close packing fractions of lognormal distributions of hard spheres

    RFR. Farr Powder Technology

    Random close packing fractions

    Lognormal distributions (and mixtures of same) are a useful model for the size distribution in emulsions and sediments.

  • Food Biophysics

    Shear elastic deformation in cells

    Analysis of the linear elastic behaviour of plant cell dispersions improves our understanding of how to stabilise and texturise food products.

  • Physical Review E

    Ever-shrinking spheres

    Techniques from random sphere packing predict the dimension of the Apollonian gasket, a fractal made up of non-overlapping hyperspheres.
