NEXAFS multiple scattering calculations of KO₂ [PDF]

Journal of Synchrotron Radiation, 2001
Since many years the oxidation of alkali metals has being attracted much interest due to the catalytic properties of metal promoters and the simple electronic structure of alkali atoms. The alkali-oxides phase diagram indicates that the interaction of oxygen with alkali metals can lead to the formation of different atomic O2- ions and molecular O2

Fluorescence and Physico-Chemical Properties of Hydrogenated Detonation Nanodiamonds

C, 2020
Hydrogenated detonation nanodiamonds are of great interest for emerging applications in areas from biology and medicine to lubrication. Here, we compare the two main hydrogenation techniques—annealing in hydrogen and plasma-assisted hydrogenation ...

Computational NEXAFS Characterization of Molecular Model Systems for 2D Boroxine Frameworks

Nanomaterials, 2022
The electronic properties of 2D boroxine networks are computationally investigated by simulating the NEXAFS spectra of a series of molecular models, with or without morphologic defects, with respect to the ideal honeycomb structure.

X-ray and Synchrotron FTIR Studies of Partially Decomposed Magnesium Borohydride

Energies, 2022
Magnesium borohydride (Mg(BH4)2) is an attractive compound for solid-state hydrogen storage due to its lucratively high hydrogen densities and theoretically low operational temperature. Hydrogen release from Mg(BH4)2 occurs through several steps.
