Description

The data-set contains the 3D reconstruction of seawater micro-droplets on cleaved calcite in n-decane measured with AFM which can be used for the assessment of pinning effects along the three-phase contact line. The reconstruction was created from force-distance curves obtained at each pixel of the AFM image following the description in the referenced paper. The reconstruction has the dimensions 1024x1024x1024 and a voxel size of 0.0383 μm × 0.0383 μm × 0.0383 μm with the values 0,1,2 representing n-decane, calcite and seawater respectively. Further, the data-set contains the original height map of the calcite surface underneath the droplet with greater accuracy with the dimensions 128 x 128, a pixel size of 0.29 μm x 0.29 μm. We recommend applying a median filter to remove instrumental artefacts. In combination, the reconstruction allows for small scale contact angle measurements and to correlate these measurements to the natural roughness of cleaved calcite.
