Ph.D. in Physics and Nanoscience, Università degli studi di Modena e Raggio Emilia (2017)
During my PhD in Physics I have installed, calibrated and validated the X-Ray Photoelectron Spectroscopy (XPS) facility at ISOF. PhD thesis link
I have studied the charge transport properties of Graphene Based Materilas (GBM), I have proposed a unique model that explains the transport properties of both single sheet and thin film Reduced Graphene Oxide .
I currently manage the XPS surface chemistry analysis facility, I am responsible for the scientific activity and technical maintenance. I am in charge of the electrical characterization of Graphene-based composites and devices inside the Graphene Faghship project. My research work is mainly focused on surface science of Graphene based materials (GBM) in the framework of Graphene Flagship Project. I work on standardization of the characterizion procedures of 2D materials , by using X-Ray Photolectron Spectroscopy for qualitative and quantitative analysis. I have proposed a new fit procedure for the quatification of the Oxygen to Carbon ration (O/C) indipendendly from thickness and substrate. I am studying the structure of Graphene Oxide and its covalent funtionalisations [6,7,8,9]. I have studied the ionic and molecualar transport and the associated mechanisms (adsorbtion and intercalation) in GBM for water purification purpose [4,5].
