Fig. 4. Rapid water transport dynamics in PTI·H2O compared with mobility in other nanoconfined environments.

Fig. 4

(A) Translational (Dt) and localized (Dloc) H2O dynamics within PTI·H2O as a function of temperature (T). QENS data were acquired at OSIRIS (open triangles and circles) and IN16B-BATS (filled symbols). Dt data for PTI·H2O are compared with measurements for water transport through AQP1 (asterisks) (14, 33) and single-walled CNTs with subnanometer internal diameter (stars) (14). (B) Relaxation times (τR = ħ/ΓR) from analysis of the Q-independent broad QENS component for PTI·H2O between 345 to 150 K (Fig. 3C) compared with water contained within larger-diameter (1.7 nm) CNTs (light brown) (29).
