Research Interests :

Natural materials are constituted by molecular/supramolecular building blocks, assembled at several hierarchical levels, which in most cases interact molecularly with water. From the point of view of a living organism, in an evolutionary perspective, a choice has to be made about how to tailor a material with respect to this interaction. Interestingly, in nature, a high variety of material’s responses to water and changes in moisture content or environmental relative humidity can be observed.

My main goal is to describe, from the molecular level upward, the effect of water “crowding” around the molecular components of some selected natural materials and to understand what molecular mechanisms are responsible for the observed responses as well as to extract biomimetic principles to be applied in several different fields, but especially for energy harvesting and conversion. To describe those interactions at the various hierarchical levels I use a multi-technique approach, developing environmental setups allowing the control of temperature and water chemical potential (either from the gas phase or with osmotic stress techniques) and following the changes occurring in the materials from the molecular level (vibrational spectroscopies), to higher supramolecular levels (X-Ray scattering, electron microscopy), to the macroscopic size (micromechanical testing) possibly measuring molar free energy and enthalpy changes (through microgravimetric and calorimetric techniques) at the same time. The experimental data are then compared with thermodynamic and mechanical modeling of the considered material.
