Fig. 3. Responsive adsorption maps for three cases of free energy surfaces at T* = 0.80, (a) harmonic potential, (b) bistable potential with Ethin = 0 and (c) bistable potential with Ewide = 0. Top row: an illustration of the free energy surface and critical parameters. Middle row: amount of adsorption-induced flexibility demonstrated by the sum of differential widths (sdw). Bottom row: density of gas released (N*) by a negative gas adsorption step, if one occurs.
