Recent advances in using Photocurrent Spectroscopy for the Characterization of Passive Films on Metals and Metallic Alloys

La Spettroscopia a Fotocorrente (PCS) viene qui presentata come tecnica d’indagine non distruttiva, utile per lo studio delle proprietà elettroniche di film passivi accresciuti su metalli e leghe metalliche. In questo lavoro sono stati studiati tramite PCS film passivi di acciai inossidabili quali AISI 304L, AISI 316L e Duplex 2507, accresciuti in soluzione 0.25 M di NaOH a 82°C, condizione simulante l’ambiente aggressivo tipico di operazioni di pulizia nell’industria del food and beverage. Il band gap dei film passivi cambia notevolmente dopo l’immersione per gli acciai 304L e 316L, con un arricchimento in Fe dei film passivi durante il trattamento. Per l’acciaio Duplex invece, il film pas…

Multidisciplinary characterization and modelling of the medium enthalpy geothermal reservoir of the Western Sicily: results from the VIGOR Project

Proposte metodologiche per la valutazione del potenziale di geoscambio: il Progetto VIGOR

In the framework of VIGOR Project, a national project coordinated by the Institute of Geosciences and Earth Resources (CNR-IGG) and sponsored by the Ministry of Economic Development (MiSE), dedicated to the evaluation of geothermal potential in the regions of the Convergence Objective in Italy (Puglia, Calabria, Campania and Sicily), is expected to evaluate the ability of the territory to heat exchange with the ground for air conditioning of buildings. To identify the conditions for the development of low enthalpy geothermal systems collected and organized on a regional scale geological and stratigraphic data useful for the preparation of a specific thematic mapping, able to represent in a …

Studio delle tanatocenosi a foraminiferi bentonici nel Golfo di Gela

THE EFFECT OF HEAVY METALS ON BENTHIC FORAMINIFERA IN THE GULF OF GELA (SICILIAN CHANNEL)

Benthic foraminifera are very sensitive to oceanographic parameter variations, to which they rapidly response through changes in the abundance and/or richness of their associations and in morphological variations of their shell. Many studies have used benthic foraminifera as bioindicators. We investigated recent benthic foraminiferal assemblages in the Gulf of Gela (Sicilian Channel, Mediterranean Sea), examining their relative abundance, specific richness and morphological abnormalities, to highlight a possible correlation with oceanographic features and the concentration of heavy metals in sediments. Sediment was sampled in summer 2006 using box corers in four stations at increasing dista…
