New technique accurately measures the water slippage in single graphene nanofluidic channels

For most viscous liquids, the solid surface of surrounding channel walls poses friction resistance to the flowing liquid, causing a loss of velocity at the liquid/solid interface. As a result, for regular surfaces the energy required for nanofluidic applications is enormous because of the tremendous hydraulic resistance inside nanoscale conduits. A new technique to accurately measure the hydraulic resistance inside graphene nanofluidic channels makes increasing the efficiencies of most nanofluidic applications possible.
