Lattice-gas modeling of adsorption on nanotube bundles at criticality
Pasinetti, P.M.; Riccardo, J.L.; Ramirez-Pastor, A.J. - In: Physica A: Statistical Mechanics and its Applications 355 (2005) 2, pp. 383-392
Adsorption thermodynamics of interacting particles adsorbed on nanotube bundles is studied through a lattice-gas model and Monte Carlo simulations. The adsorbent is modeled as one-dimensional channels of equivalent adsorption sites arranged in a triangular cross-sectional structure. Two kinds of...

Differential heat of adsorption in the presence of an order–disorder phase transition
Ramirez-Pastor, A.J; Bulnes, F - In: Physica A: Statistical Mechanics and its Applications 283 (2000) 1, pp. 198-203
We studied the coverage dependence of the differential heat of adsorption in the presence of an order–disorder phase transition, by employing theoretical mean-field and quasi-chemical approaches and Monte Carlo simulation, in the framework of the lattice-gas model. For a square lattice, with...

Differential heat of adsorption at critical regime: square, triangular and honeycomb lattices
Bulnes, F; Ramirez-Pastor, A.J - In: Physica A: Statistical Mechanics and its Applications 295 (2001) 1, pp. 71-76
We report on a Monte Carlo study of the differential heat of adsorption on, square, triangular and honeycomb two-dimensional lattices. The influence of the connectivity on the main scaling parameters in the critical regime is analyzed. The simulation data are compared with mean-field and...
