Reaction–diffusion models are widely used to model developmental processes. The great
majority of current models invoke constant diffusion coefficients. However, the diffusion of …

The chemical surface diffusion coefficient D has been determined for a lattice-gas model
where diffusion proceeds through two non-equivalent lattice sites with different activation …

Topological constraints play a fundamental role in problems involving the transfer of heat,
matter, or information in a discrete network. Flows in microporous media are the most …

We investigate the thermodynamic properties of a system of particles adsorbed on a lattice
with two nonequivalent sites, with different unit cell numbers and adsorption energies. We …

We study a model of pattern formation in an excitable medium with concentration-dependent
diffusivities. The reaction terms correspond to a two-variable Gray–Scott model in which the …

The thermodynamic and transport properties of diffusing species in microporous materials
are strongly influenced by their interactions with the confining framework, which provide the …

In this second paper the authors study the transport properties of the lattice-gas cellular
automaton presented in Paper I [J. Chem. Phys. 126, 194709 (2007)] to model adsorption …

By calculating the jump diffusion rate (Г) and the thermodynamical factor (Kd) for a layer of
non-interacting particles on a lattice with the non-equivalent bond sites we show that the …

We calculated the surface diffusion coefficient D as a function of coverage in the quasi-
chemical approximation of a system of particles on a square lattice with two non-equivalent …

We investigate surface diffusion in a system of particles adsorbed on a square lattice with
two non-equivalent sites. Analytical expression for the chemical diffusion coefficient have …
