Ice-like water structure in carbon nanotube (8,8) induces cationic hydration enhancement

It is well recognized that ice-like water can be formed in carbon nanotubes (CNTs). Here, we perform molecular dynamics simulations of the hydration of Na+, K+ and Cl- in armchair CNT(n,n) (n = 6, 7, 8, 9 and 10) at 300 K to elucidate the effect of such
