Photoelectron spectroscopy experiments and global-minimum structure search have determined the geometry of Rh19 to be a regular Oh[Rh@Rh12@Rh6] with unusual high-spin electronic configuration. The distinct stability of such a strongly magnetic cluster Rh19 consisting of a nonmagnetic element is ...
Figs. 2 and S5–10 show the distribution of each element in the perovskite before reduction, after reduction, and after reoxidation by ex situ STEM. The SFRhM perovskite initially exhibited a clean surface without any Rh aggregates (Fig. 2a), and STEM-EDS elemental maps of the as-prepared...
we detected two kinds of adsorbate species and one gaseous species at each different peak position in deconvoluted C 1sand O 1score-level spectra. This metal carbonyl formation (M-CO) could be examined by individual metal element electron transfers binding...
configuration, unique nanostructure, and possible coupled electronic effect. All the catalysts including the b-Pd@Rh-NCs, Rh black, and b-Pd-NCs show much higher activities towards the HEO in alkaline than in acidic solution. The Tafel slopes demonstrate the different mechanisms of the HEO on ...

The Δ parameter, which describes the hybridization strength between the Ce 4f shell and con- duction electron states, is defined as πV 2ρmax, where ρmax is the maximum value of the DOS and V is the hybridiza- tion matrix element in the Anderson impurity Hamilto- nian. The Δ value...
SEM images of bulk B (Fig. S5), BNS (Fig. S6), Rh NP@BNS (Fig. S7) as well as the corresponding element mapping images indicated that all samples are mainly composed of B elements, with a small amount of C, N, and O impurities. The existence of C, O, and N impurities is pos...
The unique properties imparted by fluorine atom have rendered it a popular element in functional molecules (Scheme 20). Scheme 20. Rh(III)-catalyzed C–H activation of arenes. Ketenes (R1R2C=C=O) are highly reactive reagents that have been widely used in the synthesis of complex carbonyl...
These radiative properties are also useful in the analysis of interstellar and quasar absorption of lines, as well as the photospheric abundance of the considered element in a given star [7]. The construction of kinetic models of plasma processes and the experimental investigations in thermonuclear ...
