Interfacial interaction between cerium oxide and silicon surfaces
No full textAbstract The interaction of cerium oxide films with Si substrates is investigated by means of X-ray photoelectron spectroscopy. Cerium oxide films of different thickness have been grown at room temperature by reactive deposition on different Si surfaces, namely Si(111), Si(100) and thermally oxidized Si(100). We show that cerium oxide and silicon form a silicate phase of subnanometric thickness and that the interfacial phase composition and thickness is similar on the (111) and (100) Si surfaces. The silicate phase formed at the interface contains cerium in the 3+ oxidation state, while silicon presents different oxidation states up to 4+. With a thermal annealing in O2 at 1040K the interface reaction proceeds and the silicate phase evolves in stoichiometry. We demonstrate the stability of the silicate phase towards oxidation after exposure to atomic or molecular oxygen or air. The presence of a thick thermal oxide layer on the Si surface partially limits the extent of the reaction.
Highlights ► A subnanometric silicate phase forms at the interface between cerium oxide and Si. ► The silicate phase evolves in thickness and composition after thermal treatments. ► The interfacial reaction has the same extent on the (111) and (100) Si surfaces. ► The interfacial reaction is partially limited by the presence of a silicon oxide. ► The silicate phase is stable towards oxidizing treatments
Structure of Ultrathin CeO2Films on Pt(111) by Polarization-Dependent X-ray Absorption Fine Structure
No full textWe present a study of the structure of cerium oxide ultrathin films supported on Pt(111), focused on the evolution of the epitaxial strain in films of different thickness. The stoichiometry and oxidation state of the films are determined by X-ray photoemission spectroscopy, and the surface structure, measured by low-energy electron diffraction, is compared with the results obtained by the analysis of X-ray absorption fine structure measurements at the Ce L3 edge, exploiting the polarization dependence of the cross section to probe the in-plane and the out-of-plane atomic correlations. The obtained results allow to establish the epitaxial relation between the cerium oxide film and the Pt substrate and give an accurate evaluation of the cerium oxide layer structure. The 2 ML films have a fluorite structure which is compressed in the (111) plane. The measured compression is compatible with the assumption of a coincidence lattice between overlayer and substrate, in which three CeO2 surface unit cells match four Pt unit cells. The films’ three-dimensional structure is compared with the one expected assuming the bulk-phase elastic constants. The strain is released when the film thickness is increased to 10 ML, and the lattice parameters assume the bulk values

No full textL'intervento mira a ricostruire le vicende collezionistiche e i passaggi di proprietà di un dipinto, Nudo rosso di Amedeo Modigliani, che per il suo indiscutibile fascino e la sua importanza nella produzione del pittore livornese, ha recentemente stabilito un record d'asta all'interno del mercato dell'arte
Per una riabilitazione di Pietro Fabris. Fortuna critica e nuove considerazioni.
No full textL'articolo ripercorre la fortuna critica del pittore anglo-napoletano Pietro Fabris nei secoli XIX e XX, analizzando l'evoluzione del giudizio critico degli storici dell'arte italiani in relazione all'avanzamento delle conoscenze sull'attività del pittore. Tale analisi è spunto per chiarire particolari significativi sulla vicenda biografica e artistica di Pietro Fabris e sulle sue relazioni con mecenati e collezionisti giunti a Napoli durante il Grand Tour
A_GreeNET Explorer
No full textThe LIFE+ A_GreeNet Explorer Platform is a digital tool developed within the framework of the LIFE+ A_GreeNet project to support urban climate adaptation and green infrastructure planning. The platform serves as an advanced WebGIS system designed to collect, analyze, manage, and disseminate data related to urban green areas and climate resilience measures. Its main features include user-friendly data visualization, constant updates, and the ability to generate interactive maps and databases on the quality and conservation status of green urban spaces. The platform aims to assist decision-makers, local stakeholders, and the general public in planning and implementing effective strategies for micro-forestation, soil regeneration, and urban greening by providing centralized access to environmental and planning-related data. This innovative tool highlights the importance of data-driven approaches in addressing the rising temperatures and heatwaves that affect coastal cities in the Middle Adriatic, aligning with European and national climate adaptation policies
