Supercooled Water Confined in a Silica Xerogel: Temperature and Pressure Dependence of Boson Peak and of Mean Square Displacements
2013
A silica xerogel can be obtained from an alcoxide precursor (TMOS, tetramethylortosilcate) via the sol-gel method: TMOS hydrolysis and subsequent polycondensation yields a solid, disordered, porous SiO2 matrix (average pore dimensions ~20Å). Inside the pores water is trapped and the hydration level h=gr[H2O]/gr[SiO2] can be easily controlled. The presence and temperature dependence of the boson peak (BP) in xerogel confined supercooled water was studied with inelastic neutron scattering (spectrometer IN6 at ILL, Grenoble) in xerogel samples having h=0.4 and h=0.2. After careful subtraction of the contributions arising from the matrix and from quasi-elastic scattering, the BP contribution wa…

A Feasibility Study for the Transition to Electric Mobility in the Island of Favignana
2021
The energy transition and climate neutrality are a short time scenario as climate concerns are rising fast. Small islands are natural microgrids in which the energy transition is subjected to economic and regulatory constraints and highly challenged by technical issues. As a first step, the Mediterranean island of Favignana has been considered in this study, to assess how electric mobility could impact the power system. According to the plans from the local decision makers, the island is moving towards a full public electric mobility in the near term, also due to the participation in the BloRin project. For this reason, a feasibility study about the technical and environmental impact of ele…
Smart city, mobilità, energia: nuove prospettive di sviluppo urbano al tempo della transizione
2022
The challenges of digital and ecological transition require responses and strategies involving all levels of government. The work aims at analyzing how the processes and measures related to the smart city paradigm can contribute to the achievement of the sustainable development and digitalization goals that currently affect the urban area. In particular, after recalling the multilevel regulatory framework on the subject of smart cities, the survey highlights the benefits and the risks arising from the concrete implementation of the aforementioned model in the sectors of mobility and energy, also recalling some important initiatives recently undertaken in the national legal system
Palermo senziente. Città di persone e città di sensori
2021
Nel mondo contemporaneo, razionalità e percezione non nascono più nella mente e nei sensi umani. Un recente libro curato da Grazia Concilio e Francesca Rizzo mostra numerose sfaccettature di questa questione. Quando nel 2017 Maurizio Carta introduce il concetto di città senziente, rafforza significativamente le basi per integrare ragione e sentimento urbanistico, cioè per integrare la razionalità della conoscenza strutturata e finalizzata al processo di pianificazione con le percezioni derivanti dalla “pancia” della città. Il contributo propone una visione innovativa sulla dualità analitica e valutativa che si genera tra mondo reale e mondo digitale, tra gli abitanti-utenti delle città e gl…
Material and immaterial culture of the internal minor centres. Studies and researches for the ecological transition of the Madonie inner mountain are…
2022
Presently, the European Union strategies aim at strengthening the rural areas that are characterized by a deep depopulation, people aging, and a weak employment market. In these "marginalized" areas, the urban regeneration process may be assisted by the creation of smart villages, realities that will cooperate and create innovative small towns. The Sicilian inner mountain area, in particular, consists of twenty-one villages - mostly dating back to the Middle Age - that present an attractive localization due to naturalistic, landscape and cultural features, also qualified by a well-preserved geographical area whose main building typological features were not altered during time. This paper p…
