Angstrom-scale two-dimensional nanofluidics

The creation of angstrom-scale (Å-scale) channels by stacking 2D materials has opened a new frontier in nanofluidics. Studies of Å-scale 2D nanofluidics have revealed novel insights into mass transport phenomena. We highlight progress in this burgeoning field, which could profoundly impact emerging disruptive technologies in resource separation, energy, and iontronics.
