The metallization of melted iodine observed above the temperature of 900K and pressure of 3GPa (V.V. Brazhkin et al., High Press. Res. 6 (1992) 363) has been interpreted using a percolation model of overlapping electron shells (classically accessible spheres) of virtual atoms in molecules. The...

A novel modelling framework for the simulation of the diffusive mass transport limitations occurring at GDL local scale of PEFCs is presented, in particular in relation with the distribution of liquid water in the porous media. The distinctive characteristic of this framework is the fact that...

A two dimensional steady state and isothermal model of a proton exchange membrane fuel cell is presented. This model is applied to a fuel cell with a counter-flow mode of hydrogen and air along parallel flow channels. In the flow channel and porous media, reactant flow is modelled using the...

Molecular transport in phase space is crucial for chemical reactions because it defines how pre-reactive molecular configurations are found during the time evolution of the system. Using Molecular Dynamics (MD) simulated atomistic trajectories we test the assumption of the normal diffusion in...

The static dielectric constant ε0 was calculated for structures of liquid water obtained from Reverse Monte Carlo (RMC) simulations driven by partial radial pair correlation functions on one hand and by neutron- and X-ray structure factors on the other. For this purpose, RMC simulations with...

The Naming Game is an agent-based model where individuals communicate to name an initially unnamed object. On a large class of networks continual pairwise interactions lead the system to an ultimate consensus state, in which agents onverge on a globally shared name. Soon after the introduction...
