High-resolution monochromated XPS C 1s spectra can be peak-fitted by taking into account all functionalities of the respective components of the formulation. Uncured and cured coatings based on a mixture of hexamethoxymethyl melamine and a polyester resin exhibit minor differences in terms of surface...
a TEM image of CDs (inset, particle size distribution of CDs); b high-resolution TEM image of CDs; c−f: full scale XPS spectra, high-resolution C 1s, N 1s, and O 1s XPS spectra of CDs; g, h one-photon and two-photon fluorescence (FL) spectra of protonated CDs in deionized wa...
The high-resolution XPS spectra of C 1 s shown in Fig. 4e displays five well-separated peaks at binding energy of 284.4, 285.6, 287.0, 288.3, and 290.6 eV, which are in accordance with the characteristic peaks of C = C, C–N, C–O, C = O, and O–C = O, respectively [5,29...
The XPS spectra (Fig. 3) display graphitic C 1s, O 1s, Cu and S 2p peaks for GO-COOH-CuS nanocomposites and the existence of C and O in the GO-COOH. In addition, the high-resolution C 1s spectra (Fig. 3b) exhibit three main separated peaks at 283.9 eV, 286.2 eV and ...
The decreased peak intensity of oxygen-containing functional groups from the C 1s high resolution XPS spectra in Fig. S5a and S5b indicates the reduction of GO [33]. Fig. S5c exhibits the high resolution XPS spectrum for N 1s of Bi2O3@N-G that could be analysed into different types ...
The high-resolution N1s XPS spectra of CS and CS/Mg(OH)2 films are shown in Fig. 4a. There are two N1s peaks located at 399 eV and 401–402 eV for neat CS film, which are attributed to the existence of the nitrogen atoms in the –NH2 and –NH3+ groups, respectively (Yap et ...
Survey spectra were recorded on the samples of NiCoCr and NiCoCrFe corroded in 0.1 M NaCl, followed by high resolution XPS spectra for Ni 2p, Co 2p, Cr 2p, Fe 2p, C 1s, and O 1s regions. The XPS spectra were analyzed using the Casa XPS software. 3 Results and analyses The cyc...
e Raman spectra and f high-resolution C 1s XPS spectra images of all samples the high-resolution C 1s spectrum (Fig. 3f). These results imply that the presence of a large amount of amorphous Nb2O5 and the reduction in Nb2O5 can increase the struc- tural defects and decrease...
The high-resolution C1s XPS spectra of PACs (Fig. 5c–e) can be deconvoluted into mainly three peaks representing sp2 carbon (245 ± 0.2 eV), sp3 carbon or C-OH (286 ± 0.2 eV), C-O (287 ± 0.2 eV)11. It can be seen that compared with ...
