Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishMulticanonical ensemble sampling simulations have been performed to calculate the phase diagram of a Lennard-Jones fluid embedded in a fractal random matrix generated through diffusion- limited cluster aggregation. The study of the system at increasing size and constant porosity shows that the results are independent of the matrix realization but not of the size effects. A gas-liquid transition shifted with respect to bulk is found. On growing the size of the system on the high-density side of the gas-liquid coexistence curve there appears a second coexistence region between two liquid phases. These two phases are characterized by a different behaviour of the local density inside the interconnected porous structure at the same temperature and chemical potential.

| Abstract: | Multicanonical ensemble sampling simulations have been performed to calculate the phase diagram of a Lennard-Jones fluid embedded in a fractal random matrix generated through diffusion- limited cluster aggregation. The study of the system at increasing size and constant porosity shows that the results are independent of the matrix realization but not of the size effects. A gas-liquid transition shifted with respect to bulk is found. On growing the size of the system on the high-density side of the gas-liquid coexistence curve there appears a second coexistence region between two liquid phases. These two phases are characterized by a different behaviour of the local density inside the interconnected porous structure at the same temperature and chemical potential. | |
