The group is developing research in mineralogy at nanoscale by using cutting edge research techniques such as Transmission Electron Microscopy (TEM) and Synchrotron Radiation Sources (SRS) to explore and understand the geological and biological interactions taking place in minerals. The task that they develop consists of the study at nanoscale of the metals partitioning in geological systems, the study of natural nanoparticles aggregation, the study of nanoporosity in rocks and soils, the ab-initio structure determination of nanominerals and the study of their stability. This research has a direct impact on the integral study of mineral resources (from exploration to the metallogenetic studies), on the possible applications of their minerals, on the environmental impact and the sustainability of these resources.
