1. when particles, droplets, or other small units gather together and begin to form
成核
粒子或細胞聚集形成核心

- cluster
less technical; describes any grouping without the physical-process implication

emphasizes merging of separate units into one, not necessarily around a central point
- crystallize
specifically about forming crystals, a subset of nucleation
- disperse
to break apart or scatter, the opposite of gathering into a cluster

用法筆記
Common in scientific writing about phase changes (liquid→gas, liquid→solid). The intransitive pattern often uses 'around' or 'at' to indicate the site where clustering begins. The transitive pattern takes a direct object that is the material being gathered (e.g. 'nucleate crystal growth').
