My research profession is nano-surface science using electron microscopy and optical spectroscopy. My research interest is to investigate the low dimensional water confined by carbon nanotubes or graphene. In particular, we use single-walled carbon nanotubes suspended between micro-pillars not only to confine water on the surface or in the nanospace of the tube, but also to perform resonant spectroscopy utilizing the 1D electronic structure of nanotube. We are also working on the thermal property measurements of carbon nanotubes using photoluminescence imaging spectroscopy.

My research activities at JNCASR encompass both experimental and numerical/theoretical aspects of multiphase flows. In particular, my focus is on understanding the evolution of different types of hydrodynamic instabilities such as Rayleigh-Bénard-Marangoni convection  and Faraday instability  in micro-gravity conditions. In addition, our group focuses on acousto-fluidic interactions and complex fluids. We also actively work on the development of new computational algorithms for accurately predicting multiphase flows .

Charles Baroud did his PhD at the University of Texas at Austin on the statistics of turbulent flows. He then began working in microfluidics as a post-doc at Ecole Normale Supérieure, then as a faculty member at Ecole Polytechnique, both in Paris. At Polytechnique he addressed fundamental questions of multiphase fluid flows, as well as applications of droplet microfluidics to biological questions. This work has led to the publication of over 50 articles in a wide range of journals, as well as 8 patents and the founding of a startup company. Since December 2017, he also leads a research unit at the Institut Pasteur, in Paris, where the group continues to develop microfluidic approaches to problems in microbiology and mammalian cell biology.

My main research interests are at the frontier between soft condensed matter and material science. I am especially interested in nanoscale heat transfer and friction at solid/fluid interfaces.
I am trying to understand the microscopic physical mechanisms giving rise to thermal and hydrodynamic interfacial transport.

I work at the intersection of mechanics, materials, and physics to conduct research into nanotribology (the atomic-scale origins of friction, adhesion, lubrication, and wear), nanomechanics, nanostructured materials, surface science, and scanning probe microscopy (SPM) including in situ methods. My primary focus is on using SPM and other surface science and material characterization techniques to probe the fundamental nature of materials in contact, and to apply the results to applications at the nano, micro, and macroscale. Recently I have focused extensively on the science and technology of ultrahard carbon-based thin films, ultrathin materials such as graphene, the role of environment (water and temperature) and friction and wear, and functional mechanisms of lubricant additives.

Studies of surface melting of ice have a long history going back to the pioneering idea of Michael Faraday in 1842. However, despite long term efforts lasting more than one century and a half, understanding its underlying mechanism still remains an elusive and challenging research topic. In addition, surface melting of ice is also recognised to be a key player involving various natural phenomena spanning from making snowballs and slippage on ice surfaces to electrification of thunderclouds and the destruction of ozone. Therefore, the importance of the fundamental understanding of surface melting is not limited only to condensed matter physics. In this study, with the aid of a new in-situ approach developed by us, we propose a new scenario of the thermodynamic origin of surface melting on ice crystal.
