摘要：AbstractWe consider two examples for precipitation by phase transitions, nanobubbles arising in hydrogen electrolysis, using polymer electrolyte membrane electrolysers, and liquid arsenic rich droplets in gallium arsenide crystals. We present the modelling and derive macroscopic evolution equations by formal homogenization techniques exploiting typical scales. The resulting dynamical systems are simulated. We discuss stationary solutions and their stability. This allows to validate our models.
