In terms of the detailed structure of the surfactants in the assemblies, our results also reasonably agree with what was previously reported. Regarding the hydrophobic core, the spherical staggered model of Robson and Dennis contains some of the features observed in our simulations. Zhang et al. also proposed a similar multilayered staggered core, based on their solvent Paramagnetic Relaxation Enhancements-based NMR experiments. In agreement with our simulations, these staggered models lead to smooth boundaries between the hydrophobic and hydrophilic regions, hinder the movement of the buried part of the EO chain, and point to complexity beyond a core-shell model. Our core sizes are better represented by the two-layered model of Zhang et al. than by the multilayered model of Robson and Dennis . The 2D NOESY results by Yuan et al. indicate that the EO chain should be coiled and aligned with the surface. While our ⟨P2⟩ order parameter analysis does not show evidence of strong alignment of the hydrophilic chain with the surface, the average angles between the surface normal and the EO chain are above 45 • , as shown by the angle distributions in Figure , and indicate the tendency of alignment with the surface pointed out by the authors. Although these results are in agreement with what has been previously proposed, we also provide additional insights and propose new structures. None of these works considered staggered models for nonspherical micelles, which, given the core size and overlapping we observed in our simulations. Even for the almost spherical micelles, we observed a more complex structuring than just staggering, namely, the multi-domain assemblies without penetration of water into the core, which are reported for the first time here. All of these structures also have smooth boundaries and show nonuniform density in the hydrophobic regions.
