Researchers at Surface Science Western, Western University and Mawson Institute, University of South Australia have developed a variety of X-ray photoelectron spectroscopy (XPS) protocols that allow for a fuller understanding of transition metal chemistries at surfaces. Recent work, published in Physical Chemistry Chemical Physics, provides an in-depth look at the bonding within nickel-containing alloys, oxides and halides. Previous work on nickel surfaces has allowed for semi-quantitative analysis of the nickel species present in a sample. As well, a more accurate calculation for estimating oxide film thicknesses on a nickel metal surface has been developed.
