Transient liquId states in crysTAllizing iNorganic Systems – TITANS

Submission summary

There is growing consensus that mineral crystallization from ionic solutions involves a liquid-liquid phase separation (LLPS), where a reactant-rich liquid separates from water, just as in organic crystallization. However, mineral LLPS remains elusive because of the short lifetime of the liquid phases prior to solid precipitation. TITANS will provide fundamental knowledge on mineral LLPS by addressing the most debated questions in order to: 1) assess how liquid are the reactant-rich structures, 2) determine if they are a metastable thermodynamic phase or a kinetic pattern, and 3) rationalize the intricate evolutions of the liquid, the amorphous solid and the crystal. We will combine advanced fast microfluidic mixers, in situ characterization of structure, chemistry and dynamics at the synchrotron and in the laboratory, and in and out-of-equilibrium modeling. TITANS will thus provide a reliable depiction of the ubiquitous soft matter processes preceding the crystallization of carbonates, oxalates and sulfates.
