Thanks to the deep trap that contains the ions, the Coulomb crystals can remain trapped for ... A. Krohn et al, Cold Ion–Molecule Reactions in the Extreme Environment of a Coulomb Crystal ...

Inside is a metal clicker, once the pack cools to room temperature, crystallization of sodium acetate (an exothermic process) is triggered by the clicker, which gives the sodium acetate a nucleation ...

Care should be taken when handling a hot flask or hot plate. The flasks will be reused, so the solution should not be disposed of. Cold bath - add ice to cold water in a large beaker or ...
