About

My research is devoted to the development of key enabling nano-materials for CO2 free and sustainable energy conversion systems. Main fields of application are: photovoltaics, water splitting, Li-ion and flow batteries, fuel cells, III and IV generation nuclear reactors. Basic understanding of the properties of functional nanomaterials is a focus of the research as well as upscaling of nanomanufacturing methods.  The main topics on which I focused in the 2010-2015 period can be grouped in two main activities: hierarchical quasi-1D nanostructured electrodes for PV, electrochemistry and photoelectrochemistry; high density nanocomposite as barrier layers for protection of structural materials in extreme environments (i.e. a nuclear reactor) or as water vapour and oxygen antipermeation (i.e. in organic field effect transistors). For each activity the research was funded with IIT and external funding. 

The main recent result of the activity on nanostructured hybrid materials is the demonstration of a hybrid photocathode for water splitting, competitive with its purely inorganic state of the art counterpart (paper submitted). The main result from the activity on barrier layers is the demonstration of in service improvement of the mechanical properties of a nanocrystalline ceramic coating during ion irradiation. The relevance of this results is testified by the recent admission (June 2015) to the European Energy Research Alliance – Joint Program Nuclear Materials.

The main approach followed is the gas phase self assembly for the growth of materials with controlled properties at the nanoscale. Since 2010 I optimized the Pulsed Laser Deposition technique towards this aim and developed a novel technique named Nanoparticle Jet Deposition. The first, is extremely flexible and capable of working with any kind of inorganic material (metals, complex oxides, carbides, silicides, etc.), provided a solid target is available. In fact, the process exploits a laser to vaporize the target and, by controlling the process parameters, it is possible to preserve or modify the initial stoichiometry. The latter is intended to take this exploratory phase to a more advanced stage close to applications, by developing plasma and aerosol techniques capable of realizing hierarchical nanostructures on large scale, in an economical way. Recently, I am combining this essentially physical, vacuum based, approaches with wet chemical methods, Atomic Layer Deposition, and organic semiconductors, aiming at complementing the unique transport properties and high surface area of the hierarchical quasi-1D nanostructures, developed so far, with the wide range of functionalities possible with conformal organic and inorganic semiconductors overlayers.
