Abstract:
Nanoconfined water exhibits astonishing properties that offer new opportunities in physics, biology and technology like energy-storage applications. Here we study such nanoconfined water using ab initio molecular dynamics simulations to elucidate the structure and dynamics of water monolayers in graphene-based slit pores. The significant population of dangling (or free) O-H bonds pointing toward the two confining walls, leads to topological frustration in the hydrogen bond network. This provides a novel channel for ultrafast diffusion distinct from what has been observed in bulk or interfacial water.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
