Quantitative chemical analysis based on X-ray photoelectron spectroscopy (XPS) includes elemental identification and, in many cases, quantification of the chemical states of active surface atoms. The two main parts of the analysis are subtracting the inelastic background and fitting a synthetic lineshape to the data. The analysis of transition metal oxides is typically based on their core level...

  Purpose: To recognize affective factors in delivering X-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   Materials and Methods: Since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). X-ray imaging was done to determine geometric features of liver.   Results: Rad...

We introduced the spectrum-adapted expectation-conditional maximization (ECM) algorithm to improve efficiency of peak fitting spectral data by various models. The ECM can perform using Pseudo–Voigt mixture model and Doniach–Šunjić–Gauss which are generally used for in X-ray photoelectron spectroscopy. Analyses synthetic experimental showed that proposed method quickly completed calculation esti...

We report the negative ion photoelectron spectroscopy of the hydroxymethoxide anion, H2C(OH)O-. The photoelectron spectra show that 3.49 eV photodetachment produces two distinct electronic states of the neutral hydroxymethoxy radical (H2C(OH)O⋅). The H2C(OH)O⋅ ground state (X̃ 2A) photoelectron spectrum exhibits a vibrational progression consisting primarily of the OCO symmetric and asymmetric s...

We report an angle resolved photoemission spectroscopy study of quantum critical scaling in the single-particle spectral function of a novel anisotropic metal Li_{0.9}Mo_{6}O_{17}. We find a temperature (T) scaling exponent value and also low-T angle resolved photoemission spectroscopy line shapes that are very challenging for current one-dimensional theory frameworks. These results add a new s...

X-ray photoelectron spectra provide a wealth of information on the electronic structure. The extraction of molecular details requires adequate theoretical methods, which in case of transition metal complexes has to account for effects due to the multi-configurational and spin-mixed nature of the many-electron wave function. Here, the restricted active space self-consistent field method includin...

X-ray photoelectron emission spectra of thermally reduced graphene oxide samples and carbon nanotubes (CNTs) with various oxidation degrees are presented in this paper. A method for the reconstruction differential electron inelastic scattering cross sections from energy loss photoelectrons is described discussed. The analysis part characteristic spectrum adjacent to C1 peak indicated a consider...
