## autophobicity

https://doi.org/10.1351/goldbook.A00529
If adsorption equilibrium and mutual @[email protected] of the phases is not achieved instantly, it is possible to distinguish the initial spreading tension, $$\sigma _{\text{i}}^{\unicode[Times]{x3B1} \unicode[Times]{x3B2} \unicode[Times]{x3B4} }$$, from the final spreading tension, $$\sigma _{\text{i}}^{\unicode[Times]{x3B1} \unicode[Times]{x3B2} \unicode[Times]{x3B4} }$$, when equilibrium has been reached. In the case in which $$\sigma _{\text{i}}^{\unicode[Times]{x3B1} \unicode[Times]{x3B2} \unicode[Times]{x3B4} }$$ is positive, while $$\sigma _{\text{i}}^{\unicode[Times]{x3B1} \unicode[Times]{x3B2} \unicode[Times]{x3B4} }$$ is negative, the system is said to exhibit autophobicity.
