@D01806@ of small crystals or @S05727@ particles and the redeposition of the dissolved species on the surfaces of larger crystals or @S05727@ particles.
Notes:
  1. The process occurs because smaller particles have a higher surface energy, hence higher total Gibbs energy, than larger particles, giving rise to an apparent higher @S05740@.
  2. Modified from previous definition. The definition proposed here is recommended for its inclusion of @S05727@ particles.
