Chemical reactions and physical processes occurring at the interface between minerals and fluids are naturally able to address a number of challenges that are currently beyond our technological limits.

A first example is the synthesis of mineral hard tissues in living organisms, including humans, with biomolecules achieving a nearly perfect control on their shape, size, texture, crystal structure, and composition. A second example is the synthesis of organic molecules via sequestration of carbon dioxide observed in hydrothermal vents and on extra-terrestrial environments, where minerals are believed to act as catalysts.

Despite being relatively well known at a macroscopic level, little or nothing is known about the chemistry that gives rise to these phenomena. Understanding these processes at a molecular level would be a key to learn how to mimic them.

This presentation will show recent work undertaken in my group, where ab initio, semi-empirical and classical computational methods are used to investigate the fundamental chemistry and physics of these complex systems.
