Abstract : « There is plenty of room at the bottom ».This visionary foresight of R. Feynman, introduced during a lecture at Caltech in 1959, was at the root of numerous scientific and technological developments, taking benefit of the "strange phenomena" occurring at the smallest scales. There remains however a lot to explore, in particular in the context of fluids at the nanoscales and their specific transport properties. Superfast flows in carbon nanotubes, hydrodynamic slippage, nanobubble superstability, ... are the most striking phenomena that have been unveiled over the last few years and some of them are still awaiting an explanation. Furthermore the great efficiency of biological nanopores, such as aquaporins, in terms of permeability or selectivity is definitely a great motivation to foster research in this direction. How to reach such efficiency in artificial nano-systems, and build new devices taking benefit of the strange transport behavior of fluids at nanoscales is still an open question. This lecture will introduce the various phenomena which enters fluid dynamics in nanoscale pores. This involves interfacial dynamics, slippage effects, the limits of validity of continuum transport, electro-hydrodynamics and osmotic transport, fluctuations, etc.... In particular I will discuss several examples of theoretical and experimental studies of transport inside nanochannels, showing how nanoscales can be harnessed to obtain new transport properties and the case of flows inside nanotubes will be specifically discussed.

Biography : http://ilm-perso.univ-lyon1.fr/ lbocquet Lydéric Bocquet is director of research at CNRS and professor in physics at the Ecole Normale Supérieure in Paris. His research interests are mainly curiosity driven and extend to domains at the interface between soft condensed matter, fluid dynamics and nanoscience. He combines experiments theory, and simulations to explore the intimate mechanisms of fluid interfaces from the macroscopicdown to the molecular level, with applications in the fields of material science, micro-and nano-fluidics, complex fluids, etc. His scientific objective is to harvest the unexpected fluid transportbehaviors occu rring at the nanoscales in order to propose new routes for energy harvesting and desalination. Beyond academically oriented topics, he has also a strong interest in every-day life science. He received several awards including an Advanced Grant of the European Research Council in 2010, the Friedrich Wilhelm Bessel prize of the von Humboldt foundation in 2007, as well as the Ancell condensed matter prize of the Société Française de Physique in 2011, and the Jean Protas scientific prize of the french Academy of Sciences in 2008. His scientific production consists of 133 publications in peer-reviewed journals and 70+ invited talks in international conferences.
