The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

The experiment explores the influence of collagen on the formation of calcium carbonate (CaCO3) polymorphs over two 2 h lab sessions, focusing on vaterite, aragonite, and calcite.

Porous CaCO3 particles, both micro and nano sized, were synthesized in a mixture of Ca (OH)2, hyaluronic acid (HA), glycine, NaOH and NaCl solution with supercritical carbon dioxide.

2002年6月1日 · Systematic XPS characterisation of synthetic CaCO 3 materials (calcite, aragonite, vaterite, intergrown calcite/aragonite, and dolomite) and natural calcite have been carried out and compared.

2021年11月15日 · The XPS spectra of CaCO 3 crystals showed five characteristic peaks of 689.54 ev (F1s), 532.55 ev (O1s), 401.49 ev (N1s), 347.04eV (Ca2p) and 292.23 ev (C1s). As the characteristic element of CaCO 3 crystals, Ca core-level XPS spectra showed a double spin peak, in which Ca2p 3/2 at 347.25 eV and Ca2p 1/2 at 350.70 eV (Fig. 4 F).

Ca 2p3/2 binding energy values. Ca 2p3/2-2p1/2 splitting is 3.55 eV (for CaCO3). In survey spectra of samples where magnesium is also present there can be an overlap of the Ca 2p region with Mg KLL structure. In these cases it is better to use the Ca 2s peak for quantification. Standards taken at Surface Science Western. Ca 2p spectrum of CaSO4.

1993年1月1日 · A single crystal was broken in vacuum to expose the (10 1 ¯ 4) plane of rhombohedral calcite (CaCO 3) for XPS analysis. Survey and multiplex spectra were collected under standard operating conditions with a Perkin Elmer Physical-Electronics 5600 spectrometer using monochromatic Al K α x rays.

在真空中破碎单晶以暴露菱形方解石（CaCO3）的（1014）平面用于XPS分析。 在Perkin Elmer Physical-Electronics 5600光谱仪的标准操作条件下，使用单色AlKαx射线收集调查和多重光谱。

Carbon-doped magnesium oxide (C-MgO) and calcium carbonate (C-CaCO3) were synthesized by the in situ hydrothermal treatment of Mg (OH)2 and Ca (OH)2 with carbon, and applied...

This paper reports an examination of the chemistry of single-crystal calcite (CaCO 3) using x-ray photoelectron spectroscopy (XPS). This calcite cleavage surface was examined as freshly opened in vacuum and after several different treatments, including exposure to water vapor, covered with different amounts of evaporated Mn, ion sputtered and ...
