Elisabeth Charlaix

from Wikipedia, the free encyclopedia

Élisabeth Charlaix (born October 23, 1958 ) is a French physicist.

Career

Charlaix received his doctorate in 1987 from the University of Paris VI and École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI) (Dispersion en milieu poreux: mise en évidence de longueurs caractéristiques). She completed her doctoral thesis with Étienne Guyon . She was a post-doctoral student at Exxon in their research laboratories in New Jersey, doing research applicable to oil exploration and production (inferences about soil permeability from electrical conductivity). After that, from 1989 she was at the École normal supérieure de Lyon (Laboratory for Physics with Jean-Pierre Hansen ) and then Professor at the University of Lyon I (Claude-Bernard) at the Laboratory LPMCN (Laboratoire de physique de la matière condensée et des nanostructures) . From 2010 she was at the Laboratoire interdisciplinaire de physique at the University of Grenoble.

Research activity

She deals with porous and granular media and nanofluidics. She researched wetting (partly with Jean-François Joanny ) and liquids near solid surfaces (boundary layers), among other things with an apparatus for surface forces. First she used the apparatus at the École centrale in Lyon, but then built an apparatus for her own laboratory in 1996 with some innovations (supported by her students Jérôme Crassous and Frédéric Réstagno). The device allows displacements in the Angstrom range to be measured and also allows small mechanical surface vibrations to be triggered. She used it to study the formation of liquid wetting between surfaces in granular matter, which forms in flour due to the humidity in the air, for example, and which exerts great capillary forces that increase the cohesion of the material. She was also interested in a phenomenon which, as is well known, was used in Russian military technology: if you have a material with nanopores, the filling with liquid causes the material to have a high resistance to compression. However, capillary forces are not sufficient for the filling. The 2002 investigation showed that only certain liquids slide into the pores.

Honors

In 2006 she received the Prix ​​Jean Ricard and in 2009 the silver medal of the CNRS . She is a senior member of the Institut Universitaire de France and a Knight of the Legion of Honor .
