Computational Studies of the Structure and of the Proton Transport Phenomena in Systems Derived from Barium Cerate Perovskite Structure
2007
The final task of the whole research project is the design of new ceramic materials for protonic conduction in the range of temperature 350-750 °C. To this aim, it was planned to deepen the information on the systems obtained by doping the Ce site in the BaCeO3 perovskite matrices. In these compounds, cerium has been substituted by trivalent elements (Y, In), thus creating – to fulfill charge neutrality – oxygen vacancies that could be filled by hydroxyls groups. In this way protons have been introduced in the structure. These materials are currently investigated by both experimental and computational approaches to integrate framework structure and proton transport phenomena analyses. Due t…

Microwave gas sensor based on graphene aerogel for breath analysis
2022
Exhaled breath can be used for early detection and diagnosis of diseases, monitoring metabolic activity, and precision medicine. In this work, we design and simulate a microwave sensor in which thin graphene aerogels are integrated into rectangular microwave waveguides. Graphene aerogels are ideal sensing platforms for gases and volatile compounds as they combine extremely high surface-to-volume ratio and good electrical conductivity at RF and microwave frequencies. The latter is modified by exposure to different gases, and -when integrated into a waveguide- these changes result in significant shifts in transmission and reflection scattering parameters. We model the aerogel as a graphene gr…
Assortment, but not knowledge of assortment, affects cooperation and individual success in human groups
2017
The success or failure of human collective action often depends on the cooperation tendencies of individuals in groups, and on the information that individuals have about each other's cooperativeness. However, it is unclear whether these two factors have an interactive effect on cooperation dynamics. Using a decision-making experiment, we confirm that groups comprising individuals with higher cooperation tendencies cooperate at a higher level than groups comprising individuals with low cooperation tendencies. Moreover, assorting individuals with similar cooperation tendency together affected behaviour so that the most cooperative individuals tended to cooperate more and the least cooperativ…
Quarry Island. Paesaggi in transizione
2022
Il presente abstract presenta e accompagna gli esiti di una ricerca progettuale1 compiuta sul territorio dell’isola di Favignana, inteso come un campione di paesaggio dell’antropocene. In particolare, il progetto viene adottato come disciplina esplorativa e conoscitiva e come procedura interpretativa di un complesso ed esteso sistema paesaggistico costituito dai bacini delle cave di calcarenite, la pietra con cui si è edificata nei secoli l’architettura dell’isola. Si tratta di un sistema capillare, diffuso, indissolubilmente legato alla genesi della forma urbana e alla costruzione dell’architettura, da potersi considerare a tutti gli effetti come il principio insediativo dell’intera isola.…
Behavior of rare earth elements in an aquifer perturbed by CO2 injection: Environmental implications
2019
International audience; Three cubic-meters of CO2-saturated water was injected into a subsurface fractured aquifer in a post-mined area, using a push-pull test protocol. Groundwater samples were collected before and after CO2-injection to quantify geochemical changes. CO2-injection initially reduced the pH of water from 7.3 to 5.7, led to the enrichment of major ions (Ca2+, Mg2+, and alkalinity), and dissolved trace metals (including Fe, Mn, As, and Zn) in the groundwater. Rare earth elements (REE) and yttrium concentrations were also measured in these samples before and after CO2 perturbation, to evaluate their behavior. An enrichment of total Y plus REE (REY) occurred. REY fractionation w…
Mesozoic tectono-sedimentary evolution of Rocca Busambra in western Sicily
2008
The Rocca Busambra ridge in western Sicily is a shallow to pelagic Meso-Cenozoic carbonate structural unit of the Sicilian fold and thrust belt with a variety of tectono-sedimentary features. Palaeofaults, unconformities (buttress unconformity, onlap, downlap), a network of neptunian dykes with several infilling generations, several large hiatuses, different facies and lateral facies changes, and erosional submarine and subaerial surfaces are observed. Detailed fieldwork and structural analyses have indicated the occurrence of fault planes with different orientations. These data, combined with facies studies and physical-stratigraphy analyses, allow for the distinction of different depositi…
