TL;DR: Using microbeam hard X-ray photoelectron spectroscopy, this article clarified the valence-band electronic structures and chemical states of platinum-group metal (Ru, Ir, and Pt) pernitrides.
Abstract: Using microbeam hard X-ray photoelectron spectroscopy, we clarified the valence-band electronic structures and chemical states of platinum-group metal (Ru, Ir, and Pt) pernitrides, which have been

TL;DR: In this paper, the authors show that the trivalent Bi dopant sites on the In-site in a limited concentration maintaining the chemical state of In and O. They also show that for the higher doping concentration, the secondary phase of Bi2O3 forms, even though no chemical state variation of the host In 2O3.

TL;DR: In this article, the chemical state and dispersion of the La and Co phases have been determined and the results were compared with the CO hydrogenation activity and selectivity of supported Co/alumina catalysts.
Abstract: Two series of La/alumina and CoLa/alumina catalysts have been characterized by several bulk and surface sensitive techniques. The chemical state and dispersion of the La and Co phases have been determined. The results were compared with the CO hydrogenation activity and selectivity of supported Co/alumina catalysts.

TL;DR: In this article, the influence of supports and preparation methods on the chemical state of the promoter for Pt-Sn catalysts has been studied by Mossbauer spectroscopy and no regular trend or pattern is found for the supports studied.
Abstract: The influence of supports and preparation methods on the chemical state of the promoter for Pt-Sn catalysts has been studied by Mossbauer spectroscopy. No regular trend or pattern is found for the supports studied. Impregnation with a complex compound results in the highest content up to 55% of Sn(O)+Sn (II) in the catalyst. However, if the Sn (IV) state is desired, such catalysts can be prepared and the Sn (IV) state can be stabilized using a specific preparation method.

TL;DR: In this paper, the chemical state of the adherend surface and its structural morphology have been used to define the mechanical properties of bonded joints, in particular, the chemical properties of adherend surfaces and their structural morphology.
Abstract: The state of the surface plays a crucial role in defining the mechanical properties of bonded joints, in particular, the chemical state of the adherend surface and its structural morphology have be...
