Walking grains

The Lutetium Project 2020-11-03 | To a statistical physicist, a flock of birds is just like... a very peculiar liquid. 🐦 To better understand this analogy, Olivier Dauchot, PhD, mimicks their behavior in his lab... with walking grains! Confused yet?

MORE ABOUT THE INTERVIEWEE :

Olivier Dauchot is a Belgian-born physicist, who graduated from the Ponts et Chaussées engineering school before doing a PhD in physics at Université Pierre et Marie Curie.
He started doing research at the Saclay center of CEA, where he worked on dynamical systems, turbulence, and granular materials.
Since 2011, he is a CNRS researcher (Directeur de Recherche) and works at the Gulliver lab, at ESPCI, where he started experiments on non-living active matter like the walking grains.
There, he led the Collective Effects in Soft Matter (EC2M) team, an interdisciplinary team that worked on topics ranging from liquid crystals in confined geometries, to producing synthetic platelets, or avalanches of micrometric particles.
At the meeting point of experiments and theory, Olivier Dauchot (now head of the Gulliver lab) currently works on the solid phases of active matter, the glass transition of liquids, and the rheology of granulars.

MORE ABOUT THE INTERVIEWEE:

Marine Bézagu is an alumnus of ESPCI Paris, and of Université Pierre et Marie Curie, where she obtained a master's degree in Molecular Chemistry. In 2015, she defended her PhD thesis, titled "Ultrasound-induced chemical reactions and local mixing : towards targeted chemotherapy", that was conducted between the Laboratoire de Chimie Organique, the Gulliver lab and the Institut Langevin at ESPCI Paris. She kept working on this project as a post-doctoral researcher at Institut Langevin for an extra year.
Between 2016 and 2020, she worked as a research scientist in chemical formulation for ADOCIA, a company specialized in developing innovative formulations for therapeutical molecules. She recently moved to a Research & Development Project Manager position at InnovaFeed, a young biotech company that commercializes insect proteins.

ERRATA:

A group of agitated molecules in a disordered state is the definition of a fluid phase, meaning that it applies both to liquids and gases. A more precise definition of liquids would be the following: a dense group of agitated molecules in a disordered state, where the intermolecular distance is of the same order of magnitude as the molecular size.

Carlo Marangoni is not actually the first to study the so-called "Marangoni flows". James Thomson explained correctly these flows for the first time in 1855, and some works could even date back to 1686. Source: L. E. Scriven & C.V.
