In this talk, I will discuss various experimental and theoretical results that we obtained recently in our team on the transport of water and ions in ultra-confinement. I will in particular focus on the odd properties of the water-carbon couple, which highlights a variety of exotic transport properties that we will discuss and rationalize, such as ultra-low friction and quantum friction [1,2], specific charge adsorption, strongly non-linear transport and mechano-sensitivity [3,4], …

I will show how these specificities can be used as building blocks to build a ionic machinery, from ion pumps to artificial neuromorphic behavior [5] and the development of elementary ion-based computing.
