• Together with collaborators from ENS, Paris, we measure how the electric current of an ionic fluid is generated by the flow of water through ångstrom-sized channels

​

• Only the water may pass - Removing objects by size to keep only the smallest ones is simple in theory, but it requires a sieve, membrane, or filter with holes small enough to allow only the smallest objects to pass. We engineered two-dimensional water channels by removing a single atomic plane of atoms from a sandwich made from bulk crystal with a graphene spacer. Water flowed through the channels without resistance, but the channels excluded all ions except for protons because the ion hydration shells could not squeeze through the channels.

• We studied gas flows through the angstrom scale channels, and discovered frictionless flow on flat walls of the channel. It is ballistic flow ! First time, quantum effects in gas flow are observed  at room temperature using Helium atoms as tiny ping-pong balls bouncing through a pipe (channel). Depending on whether the pipe surface is bumpy or smooth, the ball comes out of the other end slower or faster.                                                                                            Ballistic molecular transport through two-dimensional channels, Nature (2018), 558, 42

• First paper about angstrom scale capillaries published in Nature, reported the fabrication of such capillaries is widely covered in media (as below). Moving forward, my group will be exploring fundamental science of water under ultimate confinement in these capillaries.
