From: Intermediate-range solvent templating and counterion behaviour at charged carbon nanotube surfaces
a, RDF and cumulative coordination number of the solvent geometric centre of sodium for solvents in the first SWCNT solvation shell, the second SWCNT solvation shell and beyond the second SWCNT solvation shell (>12.2 Å and >11.9 Å from the SWNCT wall for NMP and DMAc, respectively). b, Snapshot of EPSR ensemble local to the SWCNT showing sodium atoms with highlighted solvation shell radii. c, SDFs of sodium around solvent molecules, at 50% threshold.
