  • Internal imaging of dense granular solids Tetrahedrons We measured the random packing fraction of the Platonic solids, and imaged the packing with newly acquired x-ray CT machine. more.
    Image of grains in the bulk Using a novel fluoroscent index matching technique, we show that the fluctuations in granular flows are remarkably similar to that observed in a dense liquids. more.

    Friction of a slider on a granular layer: Nonmonotonic thickness dependence and effect of boundary conditions

    Cohesive strength of wet grains We explain the increased stability of a wet granular pile with a new liquid bridge model. A copy of the Nature Physics paper can be downloaded here. See related News and Views, and Cover Story.
