The confinement of liquids at the nanoscale leads to a broad spectrum of new properties which are harnessed in a variety of applications, from energy harvesting, over desalination, to oil extraction. However, not only do the classical frameworks fail to give a rationale of the transport properties at these scales, also the non-linear regimes of confined liquids have been barely explored up to now. In this project, we gather a collaborative team of experimentalists and theoreticians in order to tackle these challenging questions. This is based on (i) our unique experiments allowing us to fundamentally investigate ion and fluid transport in individual nanotubes, as well as (ii) our state-of-the-art expertise on the theory and numerical modelling of electrohydrodynamic phenomena, from ab initio simulations to new theoretical molecular frameworks. Our ultimate goal is to investigate strongly out-of-equilibrium transport and propose new types of active membrane processes.

液体在纳米尺度上的限制导致了一系列新的性质，这些性质被利用在各种应用中，从能源收集、过度海水淡化到石油开采。然而，经典框架不仅没有给出这些尺度下输运性质的理论基础，而且到目前为止，对受限液体的非线性区域也几乎没有人研究过。在这个项目中，我们聚集了一个由实验者和理论家组成的合作团队，以解决这些具有挑战性的问题。这是基于(I)我们独特的实验，使我们能够从根本上研究单个纳米管中的离子和流体传输，以及(Ii)我们在电流体动力学现象的理论和数值模拟方面的最先进专业知识，从从头计算模拟到新的理论分子框架。我们的最终目标是研究强烈的非平衡传递，并提出新类型的活性膜过程。
