1997年10月1日 · XPS measurements have been performed on a series of Mg II salts (NO 3−, CO 32−, SO 42−, Cl −, CH 3 COO −), hydroxides and oxides, these latter compounds are both commercial and prepared in laboratory.

2024年10月1日 · The crystallite sizes were found to be 60 nm for pure MgO, 48 nm for Co-doped, and 60 nm for Fe-doped MgO nanoparticles. X-ray photoelectron spectroscopy (XPS) was used to investigate the oxidation states of the prepared samples.

2019年5月1日 · X-ray photoelectron spectroscopy (XPS) is one of the most powerful experimental techniques for studying the electronic structure of small gas-phase molecules [1, 2], solid materials and their surfaces [1, 3], and large molecules of biological interest [[4], [5], [6]].

XPS Spectra Magnesium (Mg) Compounds 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.

The energy separation of the higher lying cation XPS binding energies, BEs, for MgO is examined. It is shown that the Hartree–Fock BEs overestimate the separation of the Mg BE(2s) and BE(2p), because an important many-body effect is neglected in the determination of the Hartree Fock BEs.

MgO nanoparticles surface elements, state of valence and binding energy were determined from X-ray Photoelectron Spectroscopy (XPS). The XPS observation Fig. 5a. The Mg metal peak attributed...

2007年8月7日 · The XPS analysis shows the presence of magnesium carbonate in the outermost layers. Carbonate species are more evident in the samples obtained by the surfactant method whereas no significant differences can be observed by using different surfactants. Moreover, in all the nanopowders, both MgO and Mg (OH) 2 are evident.

2021年1月3日 · The multilayer (γ-Fe 2 O 3 /MgO) N=2,4,6 ultrathin films were characterized in situ using X-ray photoemission spectroscopy (XPS), as well as in ex situ using magnetic measurements.

Accordingly, this research is designed to overcome the challenge by synthesizing mesoporous MgO nanoparticles (MgO-NPs) with a new method that uses PEG 1500 as a soft template.

2016年10月3日 · This pressure gap between ultrahigh vacuum (UHV) and ambient conditions is exemplified by surface science XPS studies of the native MgO on Mg metal. Under ambient conditions, the surface of MgO is hydroxylated to Mg (OH) 2.
