Thermal image in the crystallization of organic and polymeric materials; (a) n-pentacosane, C₂₅H₅₂, cooling at a rate of 0.6 K/min from 56.1°C to 55.8°C, (b) poly(ethylene oxide) at a cooling rate of 30 K/min from the molten state, and (c) stearic acid at a cooling rate of 10 K/min from the liquid state. The temporal derivative images are shown.
