Schematic layout of the interphase between the photon processed polyacrylamide PAM surface and the water vapor domain. (a) Thermal equilibrium domain. Reference time and space scales are determined by the mean collision time tcol between the water and air molecules and the entropy of the ideal gases and the mean collision distance. The entropy S1 is given by the Sackur–Tetrode equation for the ideal gases [99]; (b) local fluctuations domain. Nanocavitations on the surface with confined molecules. The time scale is determined by the mean escape time τ of water molecules. The entropy S2 in this domain is determined by the number of microstates Ω(Νb(n), Nc(n), Εα), which specify a state of ordered arrangements between nanocavities in one hand and molecular water ensembles of fixed molecular length near the surface on the other; (c) volume matrix domain.
