Ba1–xLaxFeO3−δ perovskites (BLF) capable of conducting electrons, protons, and oxygen ions are promising oxygen electrodes for efficient solid oxide cells (fuel cells or electrolyzers), an integral part of prospected large-scale power-to-gas energy storage systems. We investigated the compatibility of BLF with lanthanum content between 5 and 50%, i...

Petrology and fluid inclusions (FI) geochemistry are increasingly used in tandem to constrain the compositional features and evolution of the lithospheric mantle. In this study, we combine petrography and mineral chemistry with analyses of noble gases (He, Ne and Ar) and CO2 in olivine, orthopyroxene- and clinopyroxene-hosted FI, as well as radioge...

Petrology and fluid inclusions (FI) geochemistry are increasingly used in tandem to constrain the compositional evolution of the lithospheric mantle. Here, we combine petrography and mineral chemistry with the first analyses of noble gases (He, Ne and Ar) and CO2 concentrations in olivine-, opx- and cpx-hosted FI from ultramafic xenoliths collected...

This study presents the results of the examination and characterisation of the wall paintings that decorate the rupestrian church named Grotta del Crocifisso, which is located in the territory of Lentini (eastern Sicily, few tens of kilometres from Catania and Syracuse). The earliest mural paintings in the church date back to the twelfth century AD...

The Pleistocene (~590-265 ka) San Venanzo volcanic complex belongs to the IAP (Intra-Apennine Province) in central Italy, which comprises at least four small Pleistocene monogenetic volcanoes plus several unrooted pyroclastic deposits with peculiar mineralogical and whole-rock chemical compositions. San Venanzo products are strongly SiO2-undersatur...

The noble gases are among the most powerful geochemical tools in different geological settings. For this reason, they represent one of the most valuable tracers of geochemical processes whose variations can be straightforwardly ascribed to magmatic/crustal dynamics. In this dissertation, noble gas (He, Ne, Ar) geochemistry applied in both seismic a...

This paper deals with the archaeometric study of lime‐based plasters found in the archaeological settlement of Scauri, located in the homonymous bay in the south‐western part of Pantelleria Island. Since 1999, archaeological surveys have led to the recovery of the huge remains of a Late Roman settlement dating back to the fourth–fifth century AD. I...

Short presentation about the present-day understanding in Planetary Geology. The topics are taken from the 2014 EMU School on Planetary Mineralogy held at the University of Glasgow I have participated to. As it is not so easy to describe in few slides all the processes that took place during the evolution of the Solar System, this presentation is n...

Here we report the discovery of a new accumulation site in the Antarctic continent with an excellent preservation of micrometeorites and cosmic spherules.

Six thin sections of meteorite samples, recovered between 15th and 16th January 2011 at Frontier Mountain (Northern Victoria Land, Antarctica) during the 2010/2011 Italian-Korean field campaign, supported by the Programma Nazionale di Ricerche in Antartide (PNRA) e Korean Expedition for Antarctic Meteorites (KOREAMET), were studied and classified b...
