nukleaatiopisteistä
Nukleaatiopisteet, often translated as nucleation sites, are locations where a new thermodynamic phase begins to form. This phenomenon is crucial in various physical processes, including crystallization, condensation, and boiling. Without nucleation sites, a phase transition might not occur even if the conditions are thermodynamically favorable, as overcoming the initial energy barrier to form a new phase can be difficult.
In condensation, nucleation sites are typically microscopic imperfections on a surface, such as dust particles or
Crystallization also relies on nucleation. This can occur homogeneously, where the new phase forms spontaneously within
