Wagner plots

Figure 19. Wagner plot for Cul-xZnxFe204 catalysts from the Cu 2p3/2 core level and Auger spectral data. Data points for standard compounds (Cu, Cu20 and CuO) are given by solid gray triangles and fresh catalyst by solid squares. Spent catalysts with x = 0.05 and 0.25 composition indicated by open diamond and x = 0.5 and 0.75 by solid circles, respectively. The Auger parameter is described by solid straight line with a slope of-1. Reprinted from Journal of Catalysis, 241, Vijayaraj M., et al., 2006, 83-95 with permission from Elsevier.

Plots of KE(a) vs. BE(p), with AP + hv shown on the other ordinate (called Wagner plots) are found in the literature and in the NIST XPS database. An example for tin is presented in Fig. 14.25. The Sn 3ds/2 photoelectron and the Sn MNN Auger electron binding energies are tabulated and plotted for the element Sn and a variety of tin compounds, showing how the chemical environment of the Sn affects the electron energies. 

Fig. 24. Plot the In (bd2/ir2kBTP2) against /Tp for hydrogen evolution data as in Fig. 4. The dashed line represents the data of Carlson and Magee (1978) for undoped a-Si H (Beyer and Wagner, 1982).

Fig. 8.23. Cells stained with propidium iodide for permeable membranes and with annexin V for phosphatidylserine can distinguish live (double negative), apoptotic (annexin V-positive, propidium iodide-negative), and necrotic (double positive) cells. This figure (with data from Robert Wagner) shows cultured bovine aortic endothelial cells the left plot displays data from adherent cells, and the right plot displays data from the floaters. ...

Nyquist plots of the interpolated impedance spectra measured at 700 mV and different times during the progressive poisoning of the anode with CO [33], (Reprinted from Journal of Power Sources, 127(1-2), Wagner N, Gulzow E. Change of electrochemical impedance spectra (EIS) with time during CO-poisoning of the Pt-anode in a membrane fuel cell, 341-7, 2004, with permission from Elsevier and the authors.)...

The legend of Tristan Isolde has been variously interpreted, probably to greatest musical acclaim in Wagner s opera of the same name. A key plot element revolves around what is mistakenly believed to be poison. Isolde, in love with Tristan but spurned by him, and unwilling to be part of an arranged marriage with his uncle, conspires to poison herself and... 

Wagner has also developed a two-dimensional chemical state plot (24-25) that makes use of the Auger parameter to distinguish between compounds of an element that have the same, or nearly the same, binding energy. In cases where the XPS chemical shift alone is not enough to determine the chemical state, these plots or the Auger parameter by itself can be used to help identify the type of compounds present In the surface.
