Monitoring the acoustic response of nanoporous materials upon gas adsorption

Abstract: Diagnostics on acoustic methods are routinely used in materials science but they are often assumed to be unsuited to probe nanoscale phenomena due to their large wavelength (?= 10-4 - 10-2 m). Yet, the adsorption/permeation footprint in nanoporous solids is all included ? albeit in an average way ? in the acoustic signal emitted by the system subjected to pressure gradients or its response to acoustic wave stimulation. Our goal is to provide a multi-scale description of the acoustic response of a nanoporous material, enabling to fully understand the response usually monitored at the macroscopic scale. Molecular dynamics simulations show a coupling between the vibrational features of the nanoporous zeolite (silicalite-1) matrix and those of the CO2 adsorbed inside, that would be responsible for the averaged acoustic response. In order to probe these vibrational features over the q-range of dispersion, we request 4 days of of beamtime on MARI spectrometer.
