Anomalous Water Flow in Sub‐Nanometer Carbon Nanoconfinement (Small 51/2025)

Sub-Nanometer Nanoconfinement Sub-nanometer confinement reshapes molecular transport, where classical hydrodynamics breaks down. Disrupted hydrogen bonds, interfacial ordering, and single-chain motion synergistically drive ultrafast water flow through carbon nanotubes and graphene channels. In article number 2508637, BoHung Kim and co-workers show molecular choreography within atomically confined spaces, revealing how quantum-level interactions yield continuum-like flow and extraordinary transport efficiency.
