Adhesion activation enthalpy

In the gas-solid interaction studies at infinite dilution, it is found that the surface free energy and surface enthalpy (or adsorption enthalpy including acid-base character) of a solute are strongly influenced by the most active sites on the solid surface. The surface free energy and surface enthalpy have been applied as a typical value of the surface, which can be directly related to the adhesion level [70].
