Quantum forces of a gas confined in nano structures

In nano domains, thermodynamic properties of gases considerably differ from those in macro domains. One of the reasons for this difference is the quantum size effects, which become important when the thermal de Broglie wavelength of particles is not negligible in comparison with domain size. In this study, it is shown that quantum forces may appear in gases confined in nano structures due to the quantum boundary layer caused by quantum size effects. In the case of experimental verification of these quantum forces, a macroscopic manifestation of the effect of the quantum boundary layer on the thermodynamic behavior of gases can be confirmed.
