TL;DR: In this article, the authors improved the description of both electron energy loss spectra and parameters characterizing the structural stability of the material compared with local spin density functional theory by taking better account of electron correlations in the $3d$ shell of metal ions in nickel oxide.
Abstract: We demonstrate how by taking better account of electron correlations in the $3d$ shell of metal ions in nickel oxide it is possible to improve the description of both electron energy loss spectra and parameters characterizing the structural stability of the material compared with local spin density functional theory.

TL;DR: In this paper, a compilation of all published measurements of electron inelastic mean free path lengths in solids for energies in the range 0-10 000 eV above the Fermi level is presented.
Abstract: A compilation is presented of all published measurements of electron inelastic mean free path lengths in solids for energies in the range 0–10 000 eV above the Fermi level. For analysis, the materials are grouped under one of the headings: element, inorganic compound, organic compound and adsorbed gas, with the path lengths each time expressed in nanometers, monolayers and milligrams per square metre. The path lengths are vary high at low energies, fall to 0.1–0.8 nm for energies in the range 30–100 eV and then rise again as the energy increases further. For elements and inorganic compounds the scatter about a ‘universal curve’ is least when the path lengths are expressed in monolayers, λm. Analysis of the inter-element and inter-compound effects shows that λm is related to atom size and the most accuratae relations are λm = 538E−2+0.41(aE)1/2 for elements and λm=2170E−2+0.72(aE)1/2 for inorganic compounds, where a is the monolayer thickness (nm) and E is the electron energy above the Fermi level in eV. For organic compounds λd=49E−2+0.11E1/2 mgm−2. Published general theoretical predictions for λ, valid above 150 eV, do not show as good correlations with the experimental data as the above relations.

TL;DR: In this paper, the depth profiles of amorphous TbFeCo films sputtered onto polycarbonate substrate were studied by X-ray photoelectron spectroscopy.
Abstract: The depth-profiles of amorphous TbFeCo films sputtered onto polycarbonate substrate were studied by X-ray photoelectron spectroscopy. Oxidized metals, oxides and hydroxides for example, and adsorbed impurities were found to exist mainly in the vicinity of the film surface and film/ substrate interface.
