Abstract

A summary of derivations related to the interfacial thermodynamics is provided, highlighting the contact angle as a measure to determine interfacial tension directly at the solid-liquid interfaces. Techniques used to directly measure the interfacial excess (or interfacial concentration) at the solid-liquid interfaces are described with examples detailing such measurements. Developing techniques, that can measure the direct interfacial concentration at the solid-liquid interfaces with elemental and chemical specificity are also highlighted here.
