TL;DR: In this paper, the effect of the support of the Cu-based catalysts on the oxidation of ethyl acetate (EtOAc), a common volatile organic compound, was explored for the use of four Rare Earth Oxide(s) (REO) as supports to obtain the Cu/REO catalysts.

Temperature-induced structural evolution of Sm nanoparticles on Al2O3 thin film: An in-situ investigation using SRPES, XPS and STM
TL;DR: In this paper, the structural evolution of Sm nanoclusters on ultrathin film of Al2O3 epitaxially grown on Ni3Al(111) substrate at elevated temperatures was investigated in-situ using synchrotron radiation photoemission spectroscopy (SRPES), X-ray photoelectron spectroscope (XPS) and scanning tunneling microscopy (STM).

Initial stages of the interaction with oxygen of samarium thin films grown on the iridium surface
TL;DR: In this article, the interaction of thin (<1 nm) samarium films deposited on a textured iridium ribbon has been investigated by thermal desorption spectrometry, and it was shown that the film of the compound decomposes in the course of interaction with oxygen, and samarium oxide grows on the Ir surface.
