Figure 4: Phase diagrams of the fusion entropies of crystalline NIC for pure NIC, NIC/HP-β-CD mixtures (90%–10% NIC), and pure HP-β-CD prepared by the PM method. Endothermic peaks were not obtained for the samples prepared by the SM method in Figure 3(b). Values are the mean ± standard deviation of three separate measurements.
