Concentration-driven phase change, i.e., precipitation-dissolution equilibrium, is quite prevalent in many natural and artificial systems. With miniaturization, new technologies operate at small enough length scales (e.g., porous battery electrodes) where surface energies are expected to be a dominant factor. Even though the precipitation reaction is integral to functionality, its connection to interfacial effects has not been analyzed in the past. Here in we study the effect of surface energies on the nucleation dynamics of the precipitate phase. We also investigate the role of curvature on precipitate growth. This study proffers avenues for altering precipitation dynamics using interfacial characteristics.
