Spontaneous Recurrence of Deposition and Dissolution of a Solid Layer on a Solution Surface.

We investigated the spontaneous recurrence of deposition and dissolution of camphor layer on the surface of camphor methanol solution. This recurrence is a novel rhythmic process concerned with solid-liquid phase transition. To elucidate the underlying mechanism, we measured the solution temperature at different times, and found that the temperature increased and decreased repetitively, correlating with the camphor layer's deposition and dissolution. These experimental results show that the solution temperature plays an important role in recurrence of deposition and dissolution.
