BIODEGRADAZIONE DEGLI IDROCARBURI: DALLE COMUNITÀ MICROBICHE MARINE AI SISTEMI READY TO USE PER IL BIORISANAMENTO
Crude oil is one of the major hazardous pollutants. A promising technology for the treatment of contaminated sites is based on biodegradation of oil pollutants by microbial populations. Several microorganisms are known to use hydrocarbons as carbon sources. In the marine environment, obligate hydrocarbonoclastic bacteria (BIC) have been defined as being ecologically important for the aerobic removal of hydrocarbons. Recent advances in microbial ecology make it possible to combine molecular and culture-dependent approaches to identify bacterial community at environmental sites. In this thesis a microbiological survey of the Priolo Bay (eastern coast of Sicily, Ionian Sea), a chronically poll…
Life Cycle Assessment di sistemi per le auto elettriche
2011
Lo sviluppo della trazione elettrica stradale, in particolare con l’uso di batterie al litio, è uno degli approcci più promettenti alle problematiche di carattere ambientale e per la diversificazione delle fonti di energia. Il lavoro descrive una delle attività svolta nell’ambito dell’Accordo di Programma Ministero dello Sviluppo Economico ed ENEA sulla ricerca del sistema elettrico. In particolare l’ENEA e il Dipartimento dell’Energia dell’Università di Palermo hanno condotto uno studio di LCA delle batterie per autotrazione per valutare le prestazioni energetico-ambientali di questi sistemi.
La Life Cycle Assessment applicata alla valutazione della sostenibilità ambientale del riuso delle batterie da trazione
2019
In un’ottica di economia circolare, le batterie da trazione rimosse dalle auto elettriche possiedono una capacità residua sufficiente per essere riutilizzate in applicazioni stazionarie di seconda vita in edifici residenziali dotati di tecnologie per la produzione di energia elettrica da fonti rinnovabili, allo scopo di aumentare l’autoconsumo degli edifici e ridurre lo stress sulla rete elettrica. In questo contesto, lo studio propone un approccio metodologico che combina la modellizzazione energetica del sistema che fornisce l’energia elettrica richiesta in una specifica applicazione, l’analisi di load – match e la Life Cycle Assessment, da impiegare per identificare la configurazione del…

Ultrafast lead-acid battery with nanostructured Pb and PbO2 electrodes
2018
Lead-acid batteries (LABs) are still extensively used in the field of energy storage, owing to a well-known and reliable technology. LABs can deliver high power and store energy for a very long time. In addition, they are reliable and easy to produce. The raw materials for their manufacture are practically unlimited, and about 95% of the materials can be recovered and reused. However, the lower specific energy storage (about 30-40 Wh kg-1), in comparison with other storage systems, limits their use in the most emerging and challenging applications, like electrical mobility, due to the high atomic weight of lead [1]. One of the principal limitations in the use of LABs in electric vehicles (E…

Nanostructured Lead Electrodes with Reduced Graphene Oxide for High-Performance Lead–Acid Batteries
2022
Nanostructured Pb electrodes consisting of nanowire arrays were obtained by electrodeposition, to be used as negative electrodes for lead–acid batteries. Reduced graphene oxide was added to improve their performances. This was achieved via the electrochemical reduction of graphene oxide directly on the surface of nanowire arrays. The electrodes with and without reduced graphene oxide were tested in a 5 M sulfuric acid solution using a commercial pasted positive plate and an absorbed glass mat separator in a zero-gap configuration. The electrodes were tested in deep cycling conditions with a very low cut-off potential. Charge–discharge tests were performed at 5C. The electrode wi…
