cRDFs from the SWCNT central axis to the CoM of species, normalized (0,1) and offset for clarity. From top to bottom: SWCNT carbons (black), NMP CoM (green), sodium ions in NMP NaSWCNT solution (purple, 30 dashed), DMAc CoM (orange), sodium ions in DMAc NaSWCNT solution (pink, 30 dashed). Shaded backgrounds correspond to the solvation shell of NMP. Solvation shell boundaries are defined by minima at (NMP) 5.9, 12.1, 17.1 and 21.9 A and (DMAc) 6.1, 11.9, 17.0 and 21.9 A from the SWCNT surface. Solvation shell density maxima are found at (NMP) 4.7, 9.8, 15.0 and 20.0 A and (DMAc) 4.3, 9.7, 14.4 and 19.4 A. Ammonia cRDF and structure are discussed in Supplementary Information 2 .
