XPS analysis of diesel oxidation catalyst samples. The catalysts were  Pt/Pd on Al2O3 on cordierite substrate. The analyses comprised fresh catalyst samples (different PGM loading), samples from a catalyst aged in engine cell run on FAME fuel, samples from a catalyst aged accelerated in engine cell (phosphorous doped FAME fuel) and catalyst samples aged in lab-scale by impregnation of potential catalyst poisons. The company was  interested in the surface composition of the different samples in terms of main elements such as S, P, Ca, Mg, Na, K, Zn Al, Pt, Pd) and in their oxidation state.

Committente:
ITALKALI - SOCIETA’ ITALIANA SALI ALCALINI S.P.A.
Nome progetto:
Qualitative and quantitative analysis of samples of mineral salts by X-ray diffraction (XRD) and X-ray Photoelecron Spectroscopy (XPS).
Durata:
6 months

A detailed structural investigation of mineral salts was committed by Italkali spa to the Palermo Division of CNR-ISMN in order to optimize the parameters of the industrial process of production of salts. The identification and the quantification of the different crystalline phases was performed by X-ray diffraction and the surface chemical composition was determined by XPS. Different salts (halite, hydromagnesite, langbeinite) were found in different proportions in the investigated samples, corresponding to the different composition of the solid phases in the steps of the industrial process.

Industrial Project

Committente:
Istituto Ortopedico Rizzoli - Bando Progetti di Ricerca Giovani Ricercatori – Ricerca Finalizzata
Nome progetto:
Nanostructured Coatings Enhancing Material Performances in Joint Arthroplasty (gr-2010-2312686)
Durata:
36 months

The main goal of the proposed project is the realization of ceramic hard coatings over the plastic bearing component of a joint prosthesis in order to drastically reduce joint wear and therefore its negative effect on prosthesis long-term survival. A combined knowledge of nanotechnologies, material science and biomechanics has the potentiality to provide innovative solutions improving the biomechanical performances as well as the long-term survival of the prosthetic implant. In this project ISMN is carrying on the activity of surface characteriztion in terms of Atomic Force Microscopy imaging and wettability measurements.
