1. Yoko Tomo, Sarthak Nag, Takamatsu Hiroshi, Observation of Interfacial Instability of an Ultrathin Water Film, Physical Review Letters, 10.1103/PhysRevLett.128.144502, 128, 14, 2022.04, We observed the instability of a few-nanometer-thick water film encapsulated inside a graphene nanoscroll　using transmission electron microscopy. The film, that was left after recession of a meniscus, formed ripples　along the length of the nanoscroll with a distance only 20%–44% of that predicted by the classical Plateau-Rayleigh instability theory. The results were explained by a theoretical analysis that incorporates the effect of　the van der　Waals interactions between the water film and the graphene layers.　We derived important insights　into the behavior of liquid under nanoscale confinement and in nanofluidic systems..
