Calculation of the chemical potentials of nanoparticles components

Simple and convenient expression for the calculation of the chemical potentials in isotropic condensed nanoparticles based on the corresponding value for the bulk phase has been obtained. In the first approximation, the dependence of surface tension on the particle size has been taken into account. For the recalculation, the surface tension and the molar volume of the corresponding bulk phase as a function of a composition should be set. Expression convenient to study composition changes during nanoparticle growth. The expression is useful for metallurgy (formation of nonmetallic inclusions), analytical chemistry (formation of precipitations), nanotechnology (formation of nanocrystals in amorphous metals), and other branches of science and technology. The proposed method can be easy generalized for anisotropic nanocrystals.
