Attività di ricerca

Sandra Dirè belongs to the Materials Chemistry Group of DII and, at present, she is  responsible of the NMR Laboratory "Klaus Muller", equipped with three spectrometers (9.4 and 7 T) for solid state and solution NMR and one EPR instrument.

She has more than twenty years experience in sol-gel chemistry and synthesis and spectroscopic characterization of hybrid organic/inorganic materials.

She has been scientist in charge for several national PRIN projetcts and one European ITN project; she participated to a COST action (2012-2016, MP1202, Hybrid Materials and Interfaces) and she has been partner of a PAT project (Grandi Progetti PAT, 2013-2017, MADELENA, Inorganic memristic devices).
