The DS 0 adsorption thermodynamics, shown in panels b and e of Fig. (ACWI and AWI, respectively) are qualitatively similar to that of DS -for each interface, with the biggest difference being the sign of E U,V (z) at the ACWI. Additionally, the value of -T S U,V at the ACWI differs by around 20 k B T between the two solutes due to larger de-structuring of the interfacial water around the DS -head group compared to that of DS 0 . A quantitative discussion comparing DS 0 adsorption with DS -adsorption (i.e. electrostatic effects) is presented in Sec. III E.
