Jan Christer Eriksson and Anatoly I. Rusanov present their views on the article entitled 'incompatibility of the Shuttleworth equation with Hermann's mathematical structure of thermodynamics'. They derive the the general free energy differential expression for a solid fluid interface to continue their discussions. They also focus on discussing the derivation of the Shuttleworth equation within a thermodynamic framework. A pure solid phase composed of a single component is considered for simplicity that is surrounded by a adsorbing and inert gas at low pressure. They also assume that the symmetry of the solid surface is sufficiently high so as to make the surface two-dimensionally isotropic. They have been able to obtain the relevant Helmholtz energy differential expression for an arbitrarily positioned dividing surface by assuming the excess number of moles of the solid component to always remain the same on the basis of the first equation.
