The process of providing sites for 1) new bubbles to form in a liquid that is boiling or supersaturated with gas; 2) new droplets to condense from a supersaturated vapor, or 3) new crystals to form in a supersaturated solution. Nucleation sites can be scratches in a surface, dust particles, seed crystals, and so on.

Nucleation is the process of forming a nucleus. It is the initial process in crystallization. Nucleation is the extremely localized budding of a distinct thermodynamic phase. It is the process in which ions, atoms, or molecules arrange themselves in a pattern characteristic of a crystalline solid, forming a site in which additional particles depos...

<molecular biology> A general term used in polymerisation or assembly reactions where the first steps are energetically less favoured than the continuation of growth. Polymerisation is much faster if a pre formed seed is used to nucleate growth. (e.g. Microtubule growth is nucleated from the microtubule organising centre, although the nature ...

A general term used in polymerization or assembly reactions where the first steps are energetically less favoured than the continuation of growth. Polymerization is much faster if a pre-formed seed is used to nucleate growth. (eg. microtubule growth is nucleated from the microtubule organizing centre, although the nature of this nucleation is not known).
