desorption
This term is used almost exclusively in chemistry, physics, and materials science to describe the reverse process of adsorption. While adsorption involves a molecule adhering to a surface, desorption is the specific act of that molecule breaking its bond with the surface and returning to the gas or liquid phase.
Because it describes a continuous physical or chemical process, the word is treated as an uncountable noun. It is typically paired with verbs like "occur," "trigger," or "measure" in technical reports and academic papers.
