Example of particle surface and volume distribution of ‘MIDAS Single’ (e.g., typically a solid, roundish bulk and shows a plateau in the particle surface distribution; left column) and ‘MIDAS Pile’ (e.g., elongated shapes, fringed rims, and no plateau visible in the surface distribution and thus less steep slope than one for the MIDAS Single particles; right column) particles. 3D images of the MIDAS Single and MIDAS Pile particles are marked with red circles in the left and right bottom images.
