The first step involves choosing the parametrization temperature, 𝑇 𝑟𝑒𝑎𝑙 0 and assigning a corresponding DPD temperature, 𝑇 𝐷𝑃𝐷 0 . The initial set (𝑇 𝑟𝑒𝑎𝑙 0 , 𝑇 𝐷𝑃𝐷 0 ) is chosen intuitively, taking into account the system characteristics. For instance, 𝑇 𝐷𝑃𝐷 0 is chosen to be < 1 when there is solid-like or gel-like phase. We evaluated several parameter sets before choosing one that is appropriate. Our chosen temperature set for parametrization is (𝑇 𝑟𝑒𝑎𝑙 0 = 293𝐾, 𝑇 𝐷𝑃𝐷 0 = 0.65 ) and the B-W interaction parameters are determined by matching the experimental air-water surface tension at 293K ( 𝛾 0 (293𝐾) = 72.8 mN/m) and interfacial density profiles obtained from ab initio and atomistic MD simulations (Figure ). The air-water surface tension from DPD simulations obtained using Eq. ( ) is converted to real unit as,
