full_question: Although not adsorption, the proportion of a tracer that appears in a substance undergoing this process is governed by the Fajans-Paneth-Hahn Law. This phenomenon is modelled at the mesoscale by the step-flow mechanism of Burton Cabrera and Frank. The Camp number equals the product of mean shear rate and the time spent “aging” during this process, which provides an alternative name for age hardening. Ions high on the Hofmeister series are better at causing proteins to undergo this process. Kosmotropic agents such as ammonium sulfate are used in protein purification schemes in order to do this to proteins, a technique known as salting out. A method of purification relies on dissolving a compound and its impurities in a hot solvent, then allowing it to cool slowly, then filtering the product. For 10 points, name this process which occurs when a seed is added to a supersaturated solution.
