16/06/2017 – L. Talini – Fluctuations de surfaces libres
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…
07/06/2017 – E. Meshkov – About the structure of a mixing zone at an unstable interface
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”…
02/06/2017 – S. Karpitschka – Marangoni Contraction of Evaporating Sessile Droplets of Binary Mixtures
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…
19/05/2017 – D. Rodney – Mechanics of fibrous materials: can Poisson’s function be below 0 or above 1/2?
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…
05/05/2017 – B. Andreotti – Dynamique de la ligne de contact et nanorhéologie
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…

10/03/2017 – D. Crowdy – Mathematical models for microstructured optical fibre (MOF) fabrication
This talk will discuss the mathematical modelling challenges in the fabrication process for a new breed of technologically important optical fibres known as “microstructured optical fibres”, or MOFs. In contrast to traditional fibres which…
10/02/2017 – T. Séon – The physics of effervescence, from bubble bursting to drop evaporation.
When a bubble reaches an air-liquid interface, it ruptures, projecting a multitude of tiny droplets in the air (see top sequence of attached figure). Across the oceans, an estimated…
