The Influence of Temperature on the Percolation Threshold in Two-Dimensional Polymer Systems

Sikorski Andrzej

The structure of a two-dimensional film formed by strongly adsorbed polymer chains was studied by means of Monte Carlo simulations. We investigated the percolation in systems consisting of flexible polymer chains. A coarse-grained polymer chains representation was assumed and polymer chains were ...

Percolation Transitions and Fluid State Boundaries

Woodcock Leslie

Percolation transitions define gas- and liquid-state limits of existence. For simple model fluids percolation phenomena vary fundamentally with dimensionality (d).In 3d the accessible volume (VA) and excluded volume(V ...

The Lennard-Jones Fluid in the Liquid-Vapour Critical Region

Heyes D.M.

The equation of state of the Lennard-Jones (LJ) fluid in the liquid-vapour (LV) critical region is investigated by Molecular Dynamics simulation (MD). The calculated pressure (P ) and chemical potential (µ) are, within the simulation statistics, flat at the critical temperature between LJ reduce ...

Percolation in Systems Containing Ordered Elongated Objects

Romiszowski Piotr, Sikorski Andrzej

We studied the percolation and jamming of elongated objects using the Random Sequential Adsorption (RSA) technique. The objects were represented by linear sequences of beads forming needles. The positions of the beads were restricted to vertices of two-dimensional square lattice. The external f ...
