Gibbs surface

WebThe nominal location of a curved diffuse interface (e.g. the Gibbs equimolar surface) can be used to describe it in the language of differential geometry commonly applied to sharp interfaces. Its spatial position can be defined in a most general way as a vector function X(4) of surface coordinates 4- A curved interface can be approximated ...

WebThermodynamically, the physical origin of the surface free energy is the excess Gibbs free energy of the matter at the interface. Atoms or molecules exposed at an interface are surrounded by fewer neighbors, such as solid, liquid, and gas phases, resulting in an anisotropic distribution of these neighbors, which is the characteristic of a surface. WebSurface free energy (or interfacial tension) in such systems involving liquid interface can be accurately measured in the presence of solute component in the bulk solution so that excess adsorption at the interface can be calculated using the Gibbs adsorption equation.
