Une première partie de cet exposé sera dédié à la présentation de la plateforme de métrologie optique que j’ai eu l’occasion de mettre en place à L’université de Londres…
The process by which sheared suspensions go through a dramatic change in viscosity is known as discontinuous shear thickening. Although well-characterized on the macroscale, the microscopic mechanisms at play in this transition are still poorly understood…
We introduce a numerical scheme to evolve functional elastic materials that can accomplish a specified mechanical task. In this scheme, the number of solutions, their spatial architectures and the correlations among them can be computed. As an example…
The extension of DNA during confinement in a nanochannel has attracted substantial attention for next-generation genomics and as a fundamental problem in polymer physics….

En fluctuant sous l’effet de l’agitation thermique, liquides et solides révèlent spontanément certaines de leurs propriétés. La mesure des fluctuations thermiques fournit donc un moyen de déterminer des grandeurs caractéristiques, par exemple mécaniques, sans avoir à appliquer de sollicitation…
The development of instability of an interface of two media of different densities, moving with acceleration, leads to the formation of a mixing zone, which is called, according to the generally accepted terminology, “turbulent mixing zone”…
The evaporation of sessile droplets of liquid mixtures is a ubiquitous natural and industrial process, relevant, e.g., for painting, for cleaning/drying of semiconductor surfaces, or for the patterned deposition of…
The mechanics of fibrous materials is both complex and intriguing. Here, we explore one class of such materials, made of the disordered entanglement of a single long coiled fiber. This architected material is of both…
Lorsque une goutte s’étale sur un substrat, le déplacement de son contour (la ligne de contact) résulte de la compétition entre forces capillaires, motrices, et dissipation. La viscosité du liquide…
