The NMR and XPS results cannot yet be reconciled and additional experimental studies are required to resolve and to understand better [Na.sub.2]O-Si[O.sub.2] liquids and glasses. Key words: XPS, high resolution, silicate glass, NMR. 792 Resume : Les progres techniques recents dans le ...
High resolution XPS analysis of chemical functionalised multi-wall carbon nanotubes (MWCNTs) and single wall carbon nanotubes (SWCNT) was done with ESCA300 (overall instrument resolution of 0.35 eV). Information to the degree of functionalisation was ascertained by argon ion bombardment of the ...
Fig. 9. High resolution XPS spectra of Co 2p, Cr 2p, Fe 2p, Ni 2p, Cu 2p, Mo 3d and O 1 s, obtained from the passive film of the Cu0.25Mo0.75 HEA coating after electrochemistry test in 3.5% NaCl solution. The above results reveal that the freshly developed HEA coating Cu0.25Mo0....
