KOH-treated and electrochemically reduced polyaniline films has been examined by a high-resolution XPS technique. The deconvoluted core level C 1s and N 1s XPS lines show clear evidence of the existence of imine, amine and multiple charged states of N, which can be conveniently explained by ...
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 ...

The high-resolution XPS spectra for N 1 s in Co/N-mC were fitted into three peaks by using XPSPeak software at round 400.8, 399.2 and 398.5 eV, assignable to pyrrolic-N, Co-Nx and pyridinic-N [26]. It has been reported that the pyridinic or pyrrolic N which successful involvement ...

model-dependent methods using fitting of synthetic spectra, still need to be used. Aims. In this work we continue the reliability confirmation and development of metallicity determinations of M dwarfs using highresolution infrared spectra. The reliability was confirmed though analysis of M dwarfs in ...
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...
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 ...
RGO incorporation increases the C/N ratio to 1.04, so the actual weight proportion of RGO can be deduced to be ~18.7%, close to the theoretical values of 20%. Figure 6 The XPS survey spectra (a), high-resolution C1s spectra (b) high-resolution N1s spectra (c), and high-resolution ...
