Résumé:

Melting of krypton layers adsorbed in models of MCM-41 porous silica and of carbon nanotubes has been simulated using Monte Carlo methods. We have shown that the melting mechanism depends on the strength of the atom-wall interaction and on the number of layers adsorbed in the pore. Every new layer stabilizes the layers already present in the system. In the carbon nanotubes we found that adsorption of the second layer leads to a freezing of the first one at constant temperature.
