On the contrary, we find that the connection between the process-level uncertainties and material-level correlations in Figure ) and (e, f) is not as straightforward. For example, given that a stronger correlation in the Henry's regime is observed between DDEC and EQeq in Figure (b, f), one might expect that lower process-level uncertainties in Figure (b) would be observed between DDEC and EQeq rather than DDEC and Qeq. However, different FFs often give rise to variations in several important features of both the CO2 and N2 adsorption isotherms simultaneously, such as the Henry's coefficient, local slope, nonlinearity, and total saturation capacity. The performance of an adsorbent is determined by an interplay of all of these features and by the competitive adsorption between CO2 and N2, and so it is difficult to capture the process-level effects from a single metric such as the correlation between uptakes at low pressure. This makes establishing a general connection between molecular FFs and their process-level uncertainties a challenging task.
