XPS analysisXPS backgroundThe recent advances in the inelastic background analysis of XPS spectra recorded with hard X-rays (HAXPES) make this method a powerful, non-destructive solution to retrieve the depth distribution of deeply buried elements. In this work, we apply this technique to study ...
X-ray photoelectron spectroscopy (XPS) was utilized to investigate the surface compositions and electronic effects of the as-prepared FeCoNiMnRu/CNFs. The XPS survey spectrum of the as-prepared FeCoNiMnRu/CNFs is shown in Supplementary Fig.15. Figure3eshows the presence of Fe0, Fe2+and Fe3+...
X-ray photoelectron spectroscopy (XPS) was used to analyze the CS/In2S3nanocomposite's chemical composition. The chemical status and elemental makeup of the CS/In2S3nano adsorbent were revealed by the findings of the XPS survey spectrum, as displayed in Fig.4a. The survey spectrum showed the...

Regarding XPS, the authors fail to report the survey spectrum, which is crucial for any elemental composition argument. The high-resolution data provided are insufficient to support their structural claims and appear suspicious. For instance, the similarity in noise profiles for purported P 2P peaks...
The digital difference spectrum technique in X-ray photoelectron spectroscopy has proved to be effective for the analysis of the functional groups introduced by surface oxidation treatment of carbon fibers. The major functional groups introduced to the carbon fiber surface by surface oxidation are hydroxy...
To investigate the effect of PECVD and plasma treatment on the samples we used surface sensitive XPS to measure the elemental composition of the toe pad shed surface (the probe depth of XPS is around 10 nm). The survey spectrum of the B-S sample (untreated shed) shows the presence of ...
(EXAFS) measurements, were employed to gain insights into the valence state and elemental composition of the prepared catalysts. The XPS survey spectrum further reveals that Hf, O, and Ru are dominant in VO-Ru/HfO2-OP (Supplementary Fig.7). The XPS of VO-Ru/HfO2-OP depicts a Ru 3d3/2...
