Abstract:
We 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.
