X-ray Spectra And Valence States Of Cations In

soft x-ray absorption (xas) and emission (xes) spectroscopies were applied to determine valence states of manganese ions in nanostructured powder of half-doped manganite obtained by milling in a ball mill. xas spectra were measured both in surface-sensitivity total electron-yield and in bulk-sensitivity total fluorescence-yield modes. o k xes and o 1 s xas spectra characterized the occupied.x-ray spectra and valence states of cations in,soft x-ray absorption (xas) and emission (xes) spectroscopies were applied to determine valence states of manganese ions in nanostructured powder of half-doped (hbox {la}_{0.5}hbox {ca}_{0.5}hbox {mno}_{3}) manganite obtained by milling in a ball mill. xas spectra were measured both in surface-sensitivity total electron-yield and in bulk-sensitivity total fluorescence-yield modes..development of the new halogen-free flame retardant system,after the intercalation reaction by the co-milling method, the phenomenon, in which the powder was firmly adher-ing on the inner wall surface of the ball-mill as shown in figure 3, was observed. this is the phenomenon where the powder is activated by the intercalation reaction and is easily adhering on the metal surface. it is considered.high thermoelectric performance by resonant dopant indium,the two intrinsic valence bands contribute to the peak zt value ∼0.7 at about 873 k for the undoped snte. the decreased lattice thermal conductivity by ball milling further boosts the peak zt value to ∼0.8. however, the zt values in both cases are quite low, below 600 k,
