Dynamical Properties in Uniform and Periodic Growth Modes of Ascorbic Acid Crystal Domain from Thin Solution Film

Abstract

There exists the threshold-sensitive dynamical transition between the uniform and the periodic growth modes in the domain growth of ascorbic acid crystals from its aqueous supersaturated solution film. The crystal growth induces the solution flow. Humidity controls the fluidity of the solution. The solution flow varies the film thickness. The threshold exists in the thickness of the solution film, and the crystal growth almost stops if the thickness becomes lower than the threshold.

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

“…Regarding phase transitions, there have been several studies on pattern formation phenomena, including crystal growth of ascorbic acid, , chemical gardens, , and breaking of generated layers. , Cyclic growth and dissolution of camphor crystals subject to cyclic temperature variation has been reported recently. , However, the emergence of rhythmic processes induced by phase transitions has never been reported.…”
