Property Changes of Multiphasic Fluids by Geometrical Confinement in Advanced Mesoporous Materials
Solid State and Surface Chemistry, Material Synthesis
Final Report Abstract
Fluids confined within nanoporous structures exhibit unique characteristics that are not comparable to those of bulk systems. Consequently, these fluids are garnering significant attention for their high potential in technological advancements. Within these confined environments, the interactions between the surface and the liquid, as well as the geometric dimensions of the pores, are crucial factors that can be manipulated to influence the fluid's properties. In the dynamic research field of fluids confined within nanopores, the NanoLiquids project has unveiled an entirely new realm of knowledge by precisely controlling liquid-solid interactions at the molecular level. Established through a successful French-German collaborative partnership, NanoLiquids combined complementary expertise in chemistry and physics, utilizing a wide array of methods actively refined in the partners' laboratories and large-scale facilities. The research techniques used encompass the synthesis of advanced porous materials and the investigation of confined fluids, with a particular focus on their phase diagrams, structure, dynamics, and modeling. The NanoLiquids project has provided new insights into the behavior of fluids within nanosized channels. Among other things, it has revealed the unique characteristics of water when confined at the nanoscale, as opposed to its bulk form. These differences pertain to its structural organization through hydrogen bonding, which is significantly influenced by interfaces, its heterogeneous molecular mobility, and its ability to crystallize or form amorphous regions. When this understanding is extended to include binary mixtures, aqueous solutions, and alternative solvents, it can have applications in various fields such as energy harvesting and storage, cryopreservation, and green as well as sustainable chemistry.
