A simulation model was developed for the quantitative interpretation of scanning ion conductance microscopy data, which has been included as a COMSOL report that includes all the information on the simulations. The scanning electron microscopy images were used to visualize the distribution of CaCO3 crystals grown on different hair surfaces. The metadata for finding the activity of hairs are categorized, where it was recorded whether or not nucleation occurred during contact. In situ synchrotron WAXS analysis of KNO3 crystallization was carried out in levitated droplets to learn why the formation of α-KNO3 was suppressed in our silicon oil-bound droplet-based experiments Cite as: Dunn, T.
