Fig. 6: Molecular mechanism of interfacial water evaporation.
From: Ceramic-carbon Janus membrane for robust solar-thermal desalination
Snapshots of the water evaporation process at 313 K and 0 and 500 ps for (a) pure water and (b) water on the CNT surface. Snapshots of the water evaporation process at 353 K and 0 and 500 ps for (c) pure water and (d) water on the CNT surface. The enlarged images show the water distribution at the membrane interface. The number of hydrogen bonds between water molecules at 313 K for (e) bulk water and (f) water at the CNT surface. The number of hydrogen bonds between water molecules at 353 K for (g) bulk water and (h) water at the CNT surface. The numbers 27, 61, 44, and 97 indicate the number of lost hydrogen bonds. (i) State evolution mechanism of water molecules changing from the bulk state to the interfacial intermediate state (i.e., interacting with the CNT).
