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 …

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 …

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 …

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 …

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 …

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 …
