P1 Transport of water through single nanotubes #CNRS
Our main objective is to perform experiments on fluid and ion transport inside individual nanotubes under diverse forcing (electric fields, pressure drops, etc.). The influence of the confining materials is a key question; we will compare carbon (CNT) and boron-nitride (BNNT) nanotubes with the same structure but different electronic properties. Recent results demonstrate that BNNTs generate huge electric currents under salt gradients, which will be explored in the context of sustainable energy harvesting (“blue energy”). Composite materials combining suprafriction properties of CNT and electrokinetic power of BNNT will be explored, as well as transport across graphene and h-BN molecular sheets. Novel nanofluidic devices like osmotic diodes or ion pumps will be designed.
