Interpretation of XPS spectra The C1s spectrum from a sample with high concentration of sp2 carbon will have a broad, asymmetric tail towards higher binding energy. One or more satellite features, several eV from the main C1s peak, will also be observed in samples with high sp2 conc...
It’s presence on insulating surfaces provides for a convenient charge reference by setting the main line of the C 1s spectrum to 284.8 eV (although values ranging from 285.0 eV to 284.5 eV have been used in some cases, remember to check for this value when looking for binding energy refere...
The XPS spectrum of raw coal shows that the elements of raw coal are mainly consists of carbon and oxygen, a little of sulfur and silicon. The fitting map indicates that the content of carbon decrease with the increasing density; oxygen is just the opposite. C-C and C-H are the main ...

Survey spectrum from barium oxide showing various barium and oxygen peaks and a carbon peak. 氧化钡全谱,图中出现了钡和氧的多个峰和碳峰。 为了说明XPS谱,在宽能量范围内扫描了一张氧化钡的全谱。在这张谱上有多个钡和氧的峰以及表面杂质碳峰。用现代XPS能谱仪,这张氧化钡的谱采集约10秒钟。由于氧化...
“[…] we have found the carbon 1s line from the pump oil ideallysuited for use as a calibration line. In fact, there is usually no difficultyin distinguishing this line from the rest of the spectrum since its relativeintensity increases with time.”——K. Siegbahn ...
The resulting algorithm can predict the spectrum of any disordered material made of carbon, hydrogen and oxygen. “The predicted spectra are remarkably close to those obtained experimentally. This opens the door to better integration between experimental and computational characterisation of materials”, ...
may stimulate the development of metal-free electrocatalysts for other key energy conversion processes including hydrogen evolution and oxygen evolution reactions and largely expand the spectrum of catalysts for energy-related electrocatalysis reactions. ...
Scouts out jdx files containing the absorption spectrum of several substances 2-calibrate Last updated: 2022-07-24Essentially calibrates my spectrophotometer and to see if it's actually reliable or not. genome1 Not quite ML-related, but basically test out a lot of my hypotheses about yeast, ...
A few nanometers of adventitious carbon on a sample can dramatically affect the survey spectrum of that sample. Quantification may be inaccurate when using peaks of significantly different energy. The intensity of higher binding energy peaks may be reduced relative to their counterparts at lower...
