Crystallization is the natural or artificial process of formation of solid crystals from a uniform solution. Crystallization is also a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.

Positron emission is when a proton is converted to a neutron, a positron and a neutrino. It is usually found when elements decay into lower elements.

Positron emission is a type of beta decay, sometimes referred to as "beta plus"In beta plus decay, a proton is converted, via the weak force, to a neutron, a positron (also known as the "beta plus particle", the antimatter counterpart of an electron), and a neutrino.

Neutron capture is a kind of nuclear reaction in which an atomic nucleus collides with one or more neutrons and they merge to form a heavier nucleus. Since neutrons have no electric charge, they can enter a nucleus more easily than charged particles which are repelled by electrostatic repulsion.

Critical point is when an element reaches an critical temperature or pressure. And it's also the point when an element changes into a different shape (gas, solid, liquid)

When the surface tension attractive forces are between unlike molecules, they are said to be adhesive forces. Adhesion causes liquid molecules to stick to a solid surface.

An intramolecular force is a type of chemical bond, typically between macromolecules, that does not involve the sharing of pairs of electrons, but rather involves more dispersed variations of electromagnetic interactions. The intramolecular force is the dominant type of bond between supermolecules in supermolecular chemistry. Intramolecular forces are critical in maintaining the three-dimensional structure of large molecules, such as proteins and nucleic acids, and are involved in many biological processes in which large molecules bind specifically but transiently to one another. There are four main types of non-covalent bonds: hydrogen bonding, ionic interactions, Van der Waals interactions, and hydrophobic bonds.

In terms of chemistry, intramolecular force is what is the cause of molecular auto assembly. (the molecule is directed to form a specific shape through noncovalent forces; such as hydrophobic forces, hydrogen bonding and van der Waals forces.)
