“…Comparing E b between molecules with different atom numbers may lead to misinterpretation because MD simulations are performed on an atomic scale (interested in particle–particle rather than object–object interactions). 33,34 The authors propose to evaluate the adsorbent/adsorbate interaction via E b per atom (eqn (2)–(4)), which is calculated by dividing E b (of eqn (1)) by the total number of particles of each MC substance to assist E b in a more objective assessment of the interaction. E b = −[ E all − ( E sub+sol + E inh+sol ) + E sol ] E b per atom = | E b |/49, for MC1 E b per atom = | E b |/51, for MC2 E b per atom = | E b |/15, for MC3 E all , E sub+sol , E inh+sol , and E sol in eqn (1) are the boxes' total energy comprising all species, substrate and solution, inhibitor and solution, and the standalone solution at the last MD stages (after 1.0 ns of trajectories).…”
