“…Equations , , and provide a general thermodynamic methodology for predicting the adsorption stress and strain induced by mixture adsorption based on the theoretical adsorption isotherms, which depend on the sample volume, V , which varies due to the deformation. The theoretical adsorption isotherms can be determined by different means, similarly as it is done for single component systems: in particular, by using molecular level models of density functional theory , and Monte Carlo simulations, , or common phenomenological equations with parameters fitted against the experimental data, like Langmuir, Dubinin–Radushkevich, and Derjaguin–Broekhoff–de Boer, among others. Note that the sample volume, adsorption isotherms, thermodynamic potential, and other extensive characteristics can be expressed in the reduced units, as is customary in the adsorption literature, per unit mass of adsorbent.…”
