Dr. Mario Santoro (Responsabile)
Sezione Sesto Fiorentino – LENS
Researcher CNR
santoro@lens.unifi.it

Dr. Mario Santoro research activities are related to the physics and technology of materials under extreme conditions of high pressure (from 0.1 to 250 GPa) and at low / high temperature (10-5000 K), in particular with respect to: 1) study of structural and dynamic changes and phase transitions in crystalline solids, amorphous solids, liquids and supercritical fluids ; 2) synthesis of new polymeric materials, new hard alloys, and new nano-composite materials; 3) chemical reactivity of simple molecular systems. These studies are mainly carried out by means of: a) Raman and micro-Raman “imaging”, absorption and reflectivity UV-VIS-IR Fourier transform; b) X-ray diffraction; c) X-rays inelastic scattering, d) X-ray absorption spectroscopy (XAS).

Dr. Lorenzo Ulivi
Istituto dei Sistemi Complessi (ISC)
Researcher CNR
lorenzo.ulivi@isc.cnr.it

Dr. Lorenzo Ulivi research activities are mainly focused on the study of: 1) molecular solids under extreme pressure conditions, 2) materials for hydrogen storage, such as metal hydrides and clathrate hydrates. Recently he has addressed issues related to ice and solid water-hydrogen mixture at high pressure. The studies are carried out using an experimental approach based on Raman spectroscopy, infrared spectroscopy, X-ray diffraction and neutron diffraction and spectroscopy.

Dr. Andrea Ponzoni
Istituto di Ottica (CNR-INO)
Researcher CNR

Dr. Andrea Ponzoni graduated  in physics from the University of Parma in 2000 and got a PhD in Materials Engineering at the University of Brescia in 2006. Currently he is involved in studies of oxide semiconductors. His research activity is devoted to the synthesis and characterization of nanostructured metal oxides for the development of gas sensors and artificial olfactory systems (electronic noses) for applications in the environmental, food, safety and security. These activities were supported by the following projects in which AP was the principal investigator for CNR-INO unit No. 313110 in FP7 projects “SNOOPY – Sniffer for concealed people discovery”, the Lombardy Region – CNR “SUSBIOREM – New approaches and methodologies for bioremediation of water contaminated by chlorinated aliphatic solvents “, Regione Lombardia – CNR” FHfFC – Future Home for Future communites “.

Dr. Federico Gorelli
Sezione Sesto Fiorentino – LENS
Researcher CNR
gorelli@lens.unifi.it

The research activity of Dr. Federico Gorelli is  focused on materials  at  very high pressures. The experimental investigations are based on vibrational (Raman spectroscopy and infrared absorption at LENS of Florence), X-rays diffraction and inelastic scattering (at LENS of Florence and at the European synchrotron ESRF in Grenoble). The high pressures are achieved through diamond anvils cells, designed and developed at LENS. Dr. Gorelli skills are related to: vibrational spectroscopy (Raman, IR), X-ray diffraction, high pressures technology (diamond anvil cell (DAC) and hydrothermal cells), preparation of samples in DAC (cryogenic loading), laser heating in DAC, development and design of vacuum chambers for high and low temperatures, design and development of engines for remote control.
