We performed molecular dynamics simulations in the microcanonical ensemble (MEMD) for a “simple” fluid confined between two solid substrates. From the calculation of the intermediate scattering function F(k∥,t) and through the memory function formalism, we extract material (i.e. transport and thermodynamics) coefficients in the vicinity of the liquid-gas phase transition. Our results show that approaching the limit of stability (i.e. the spinodal), the dynamics of the system changes markedly.
