Percolation Processes

Measurements of the MHz-frequency dielectric properties of partially hydrated lysozyme powders have demonstrated protonic conduction at the protein surface (Careri et al., 1985). The dependence of the dielectric response on hydration level shows, at a threshold value of the hydration, the explosive growth characteristic of a phase transition (Careri et al., 1986). This behavior will be seen to follow closely the percolation model.
