Following a fruitful stay of Laurent (joined for two weeks by Cecilia) in Osaka to work with our colleagues Yasutaka Yamaguchi and Takeshi Omori, we have published several articles on the molecular modeling of liquid-solid friction. In particular, Cecilia's first paper discusses the determination of the hydrodynamic wall position in molecular dynamics simulations, and has been published as a communication in the Journal of Chemical Physics. We also published an article discussing how liquid-solid slip can be characterized with equilibrium simulations in finite-size systems, and another article on strong finite-size effects on interfacial friction. A fourth article is still under review.
