Scale Oddity in nanofluidic transport*

In this talk, I will discuss various experimental and theoretical results that we obtained recently in the Micromégas team on the transport of fluids and ions in the ultra-confinement. I will in particular focus on the odd properties of the water carbon couple, which highlights a variety of quite exotic transport properties, that we will discuss and rationalize: ultra-low friction, specific charge adsorption, non-linear transport, mechano-sensitivity, …
I will show how these specificities can be used as building blocks to build a ionic machinery, from ion pumps to artificial neuromorphic behavior.
