Nucleation is typically defined to be the process that determines how long an observer has to wait before the new phase or self-organized structure appears.
Nucleation, the initial process that occurs in the formation of a crystal from a solution, a liquid, or a vapor, in which a small number of ions, atoms, or molecules become arranged in a pattern characteristic of a crystalline solid, forming a site upon which additional particles are deposited as the crystal grows.
Nucleation is a physical process in which a change of state — for example, liquid to solid — occurs in a substance around certain focal points, known as nuclei.
Nucleation is a process that initiates phase transitions. Since the classical work of Gibbs on nucleation thermodynamics at the end of the nineteenth century, research into nucleation processes has been spread into a huge variety of scientific fields.
Nucleation is the process where droplets of liquid can condense from a vapor, or bubbles of gas can form in a boiling liquid. Nucleation can also occur in crystal solution to grow new crystals.
Nucleation is the formation of a stable “nucleus” or “seed,” which requires overcoming an initial energy barrier. This can occur through two mechanisms. Homogeneous nucleation is the spontaneous formation of a nucleus within a uniform parent phase, like pure water freezing in mid-air.
Nucleation is the first step in the self-assembly or self-organization process that results in the creation of a new thermodynamic phase or structure. Nucleation is the mechanism that decides how long an observer must wait for a new step or self-organized structure to appear.
Nucleation is defined as the initial process by which a new phase or structure forms within a material, often through the aggregation of atoms or molecules.
Most nucleation processes are physical, rather than chemical. Nucleation normally occurs at nucleation sites on surfaces contacting the liquid or vapor. Suspended particles or minute bubbles also provide nucleation sites. This is called heterogeneous nucleation (Lecture 12).
Nucleation is defined as the initial process in crystal formation from a solution, liquid, or vapor, where a small number of ions, atoms, or molecules arrange into a characteristic pattern of a crystalline solid, creating a site for further particle deposition as the crystal grows.
