An XPS and Scanning Polarization Force Microscopy Study of the Exchange and Mobility of Surface Ions on Mica
Abstract
Potassium mica was treated with different ionic solutions to replace the naturally occurring K + on the surface by Ca 2+, Mg 2+, and H + ions. The extent of the exchange was monitored by variable emergence angle X-ray photoelectron spectroscopy (XPS). Scanning polarization force microscopy (SPFM) was used to measure the mobility of the surface ions as a result of water adsorption when the mica is exposed to different humidity levels.

X-ray photoelectron spectroscopy and X-ray diffraction experiments have provided evidence that monovalent anions at water/mica interface share hydration shells with innermost cations.
“X-ray photoelectron spectroscopy and X-ray di raction experiments have provided the evidence on monovalent anions at the water / mica interface showing that the hydration shells are shared with the innermost cations [38,39].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
