Earlier studies of researchers at the University of Manchester have shown that, when filled with water, such channels rearrange it into one or two layers of H<sub>2<\/sub>O molecules with strongly suppressed dielectric permittivity, or form a room-temperature two-dimensional ice phase. Now, a collaboration between the University of Manchester and Sorbonne Universit\u00e9 have found out how water and dissolved ion transport are coupled in such confinement. They have demonstrated a transistor-like electro-hydrodynamic effect: An applied bias of a fraction of a volt can increase the measured pressure-driven ionic transport (characterized by streaming mobilities) by up to 20 times. This gating effect is observed in both graphite and hexagonal boron nitride channels but exhibits marked material-dependent differences. This highly nonlinear gating of fluid transport under molecular-scale confinement may offer new routes to control molecular and ion transport, and to explore electromechanical couplings that may have a role in recently discovered mechanosensitive ionic channels.<\/p>\n<p class=\"button\"><a target=\"blank\" href=\"https:\/\/doi.org\/10.1038\/s41586-019-0961-5\" class=\"uom-button\">Read more here - DOI https:\/\/doi.org\/10.1038\/s41586-019-0961-5<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Transistor-like operation of hydrodynamic nano-channels Van der Waals assembly of two-dimensional materials allows the creation of artificial channels with \u00e5ngstr\u00f6m-scale precision, opening new ways to fabricate nanometre scale fluidic devices.
