For roughly 15 years, I am particularly interested in the dissolution of minerals, studied from the point of view of physics. This includes:
1) The molecular mechanisms at the basis of dissolution.
Ex.: study of the thermodynamics of one single atomic event during dissolution (see article in PRL).
Ex.: prediction of macroscopic dissolution rates from atomic measurements (see article in J. Phys. Chem. C).
2) The use of original physical techniques to access to reliable dissolution rates.
Ex.: holographic interferometry to measure the dissolution rate of gypsum (see article in GCA).
3) The possibility of assessing the validity of dissolution rate measurements.
Ex.: hydrodynamic survey of the measured dissolution rates of gypsum (see article in GCA).
Ex.: hydrodynamic and chemical survey of the measured dissolution rates of calcite (see article in J. Phys. Chem. Lett.).
4) The link between dissolution and durability of mineral materials.
Ex.: evidence of pressure dissolution at the origin of the wet creep of gypsum plaster (see article in CCR) [industrial collaboration].
5) The interplay between evaporation and dissolution.
Ex.: study of the deposit due to the evaporation of a water droplet on a soluble substrate (see article in PRL and article in Colloids Surf. A).

- Gel cracking (ex.: EPJE article)
- Dynamics of soft glasses (ex.: PRL article)
- Wet granular matter (ex.: PRE article)
- Recycling of printed paper electronics (ex.: Composite Interf. article) [industrial collaboration].
