TL;DR: In this article, the results of density functional theory calculations and measurements using X-ray photoelectron spectroscopy of Co-nanoparticles dispersed on graphene/Cu are presented.

TL;DR: In this paper, the growth of the oxide layers during the PEO treatment was monitored using a digital camera and the sparks formed on the surface of niobium were analyzed, and the effect of the anodisation voltage on the oxide layer thickness (from less than 1μm up to 150μm), incorporation of the electrolyte solution species (the relative content of Nb in the coatings dropped from 36.5 to 0.7 at%), adhesion strength (the Lc2 increased from 6.31−±-0.38 to 14.10−

TL;DR: The concentration of powder added to the solution changed the chemical composition and morphology of PEO coatings on the Ti-15Mo alloy surface, and calcium and phosphorous compounds were detected in the coatings formed on the substrate by the PEO process at 300V.

TL;DR: In this article, the degradation process of APbX3 hybrid halide perovskites was analyzed using X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT).

TL;DR: In this paper, XPS data revealed the presence of mixed Ce3+ and Ce4+ states, while oxygen defect peak decreased after annealing owing to the defect elimination during oxygen diffusion into the highly defective ceramic.
