Rich ELNES structure in L 2,3 -edges. White line ratio and energy shift used to determine oxidation state. Share spectra with your fellow EELS users from around the world.

Oct 1, 2000 · This paper reports our current progress in applying EELS for quantitative determination of Mn and Co valences in magnetic oxides, including valence state transition, quantification of oxygen vacancies, refinement of crystal structures, and identification of the structure of nanoparticles.

Nov 1, 2021 · Through atomic-scale visualization by ETEM and elemental identification by in situ EELS, we found that the cobalt catalyst (composed of Co–Co 3 C) was activated through carbon dissolving in near-surface.

Aug 1, 2007 · In this work, electron energy loss (EEL) spectra (low- and core-loss spectra) obtained from CoO and Co 3 O 4 particles have been collected from specimen areas of different thicknesses, i.e. from the bulk regions towards thin edge regions, in order to probe the fine structural changes of O-K and Co-L edges, and further attempt to understand the ...

The American eel is an elongated fish with a single fin that extends down the back, around the tail and up the belly towards the vent. They are usually brown to gray on the back, fading to yellow on the belly.

May 4, 2022 · The in-situ TEM, STEM, and EELS results provide direct evidence of the microstructural and chemical evolution of Co/Zn-ZIF during pyrolysis, producing nanoclusters and nanoparticles of Co as pyrolysis progressed.

Fishing in Colorado means opportunity and chance to catch some 35 species of both warm- and cold-water fish. You can fish for the famed rainbow trout in a cool Rocky Mountain stream or troll for walleye on a sunny plains reservoir. And Colorado offers everything in between, too.

Figure 3429d shows the as-measured and background-subtracted Si L 2,3 EELS spectra of CoSi and CoSi 2. The spectra for both silicides have Si L 2,3 edge onsets located at 100.6 eV, while the Si ELNESs are slightly different.
