Joint Postdoctoral Position (18 months)

Laboratoire Interdisciplinaire de Physique (LIPhy), Grenoble, France
Instituto de Acústica, Universidad Austral de Chile (UACh), Valdivia, Chile
Available now (Starting date Nov. 2021)

Acoustic Response of Fluid Adsorption and Transport in Nanoporous Materials

This project employs a theoretical multiscale strategy based on molecular simulation and continuumlevel
homogenisation techniques to unravel the acoustic signature of fluid adsorption and transport in
nanoporous solids. By varying the working fluid, pressure, and temperature, the role of adsorption
and transport types in acoustics will be probed. Unraveling such coupling between these phenomena
will pave the way for acoustic operando monitoring as well as for acoustic stimulation/control for
separation and catalysis in nanoporous materials. In the first part of the project (LIPhy), the
postdoc will carry out molecular dynamics simulations to determine both the acoustic properties
of the fluid/solid system by probing its phonon spectrum and its response to acoustic stimulation.
Transverse and longitudinal sound velocities, as derived from mechanical coefficients obtained using
molecular simulation, will be compared with experimental data available through a large consortium.
Monte Carlo and molecular dynamics simulations will be also used to assess diffusivity, permeability
and adsorption constants to predict the macroscopic acoustic behaviour by incorporating these
coefficients in continuum homogenisation-based models to be developed in the second part of the
project (UACh).

Practical aspects
Applicants should have a PhD in Physics, Physical Chemistry, or Acoustical Physics with some
theoretical background in adsorption, diffusion, and transport in porous materials. Previous experience
in statistical mechanics applied to these problems and/or acoustical properties of porous media
is required. Experience on homogenisation methods applied to upscaling in continuum mechanics
is desirable. This research project is part of a larger research programme “ACOUFEN” involving
a strong collaboration between experimentalists and theorists (Montpellier/Grenoble/Valdivia).
The position is available from Nov. 2021 and lasts for 18 months: the postdoc will first spend 9
months in Grenoble, France and then 9 months in Valdivia, Chile (significant financial support is
provided to cover travel expenses). The net take home salary depends on the number of years of experience
after PhD but is at minimum 2050 EUR/month in France and 1300000 CLP/month in Chile.

Application
Applications will be reviewed on a rolling basis. The applicants should provide a CV with a list of
publications, a letter of motivation, and the names and e-mail addresses of 3 references to: B. Coasne
at benoit.coasne@univ-grenoble-alpes.fr and R. Venegas at rodolfo.venegas@uach.cl.
