摘要：
The authors report the observation of a fluctuation-induced first order phase transition between two states of adsorption at a wall-liquid interface. WDA density functional theory modified to enable input of the measured bulk equation of state is used to confirm the critical nature of the mean-field transition. MD computer simulation results show a first-order phase transition associated with dramatic collective fluctuations in the amount of adsorbed fluid. The qualitative appearance of the large-scale fluctuation events is described.
