• X-ray absorption near-edge structure (XANES) spectroscopy (2014, background): “The centroid position is an excellent measure of oxidation state of Fe when a material is composed solely of either ferrous or ferric iron, an Fe2+ pre-edge can be observed at a centroid position of 7112 eV and for Fe3+ 1.5 eV higher in energy at 7113.5 eV (cf., Wilke et al. 2001, 2004, 2005, 2009).”
• XANES calibrations for the oxidation state of iron in a silicate glass (2003, methodology): “Previous work has demonstrated the potential of K-edge XANES spectroscopy for the quantitative estimation of Fe3+/ SFe ratios in silicate and oxide minerals (Bajt et al. 1994; Delaney et al. 1996, 1998; Dyar et al. 1998, 2001, 2002; Wilke et al. 2001).”
• A pre-edge analysis of Mn K-edge XANES spectra to help determine the speciation of manganese in minerals and glasses (2009, background): “Such non-linearities in correlations between valence and pre-edge energy and between coordination number and pre-edge intensity were demonstrated previously for titanium, iron, and chromium (Farges et al. 1996; Wilke et al. 2001; Farges 2008).”
• Iron (III)-silica interactions in aqueous solution: Insights from X-ray absorption fine structure spectroscopy (2003, methodology): “The intensity, shape and position of the pre-edge features reflect the redox state and symmetry of Fe sites (Wilke et al., 2001).”
• Iron biomineralization by anaerobic neutrophilic iron-oxidizing bacteria (2009, methodology): “1 eV (Wilke et al., 2001).”
