Adsorbate
Definition
A fluid substance (gas, liquid, or dissolved solute) whose molecules are attracted, retained, and concentrated as an extremely thin molecular film upon the surface of a solid or liquid substrate (the adsorbent). The adsorbate constitutes the mobile component within the system prior to adhesion and the resulting layer on the interface after the process. Its energetic state and molecular dynamics change radically upon interacting with active sites.
