The stability of a pile of steel balls formed in a thin cell is studied for different liquids and air. The dependence of the angle of repose (AOR) on the medium and the cell thickness is examined. The AOR is observed to increase considerably with a decrease in cell width. In a thin cell (width...

The field of mesoscale physics is concerned with length scales which lie in the sub-micron to millimetre range. As a subject, it covers complexity, disorder, cooperative effects and structure-property relationships. Much of modern material science can be found in this regime and it remains a...

This paper reports progress in the 3D pore-scale micro-CT imaging of multiple fluid phases during drainage experiments in porous materials. Experiments performed on a sintered monodisperse bead pack and a Berea sandstone sample are described. It is observed that the residual (trapped) wetting...

We demonstrate the capability of X-ray micro-computed tomography to image the micro-structure of human cortical bone. At 5μm voxel size we observe the complex morphology of the Haversian network in three dimensions. The local thickness of Haversian canals is measured using a maximal sphere...
