摘要: The problem of computing accurately the long-range Coulomb interactions in physical systems is investigated focusing mainly on atomistic simulation fluids sorbed porous solids. Several articles involving theory and computation charged are reviewed, order to explore possibility adapting or developing methodology field computer sorbate molecules inside nanostructures modeled through a three-dimensional (crystal frameworks), two-dimensional (slit-shaped pores), one-dimensional (cylindrical pores) replication their unit cell. For this reason we digitally reconstruct selected paradigms microporous structures which exhibit different spatial periodicities such as zeolite crystals MFI FAU type, graphitic slit-shaped pores, single-wall carbon nanotubes study sorption CO(2), N(2), H(2) via grand canonical Monte Carlo simulation; predicted data compared with experimental measurements found elsewhere. Suitable technical adjustments use conventional Ewald technique, whenever it possible, prove be effective electrostatic all categories studied work.
