Data for Disordering effect of the ammonium cation accounts for anomalous enhancement of heterogeneous ice nucleation

Theoretical calculations are shown to be consistent with new experimental measurements aimed at finding the maximum magnitude of the effect. The implication of this study is that the ice-nucleating sites and surfaces of many inorganic ice nucleators are either polar or charged and therefore tend to induce formation of hydrogen ordered ice clusters. This work corroborates various literature reports indicating that some inorganic ice nucleators are most effective when nominally neutral and implies a commonality in mechanism between a wide range of inorganic ice nucleators.<br><br>Dataset contains: Pollen_NH4Cl.csv Pollen_NaCL.csv Feldspar_NH4CL.csv Feldspar_NaCl.csv Mean_freezing_temperatures.csv
