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.

NEXAFS study of electronic and atomic structure of active layer in Al/indium tin oxide/TiO2 stack during resistive switching

Science and Technology of Advanced Materials, 2016
We have studied the stability of the resistive switching process in the Al/(In2O3)0.9(SnO2)0.1/TiO2 assembly grown by atomic layer deposition. Besides electrical characterization the effect of electric field on the atomic electronic structure of the TiO2

NEXAFS study of carbonate substituted bioapatite

Journal of Physics: Conference Series, 2021
Abstract The investigation of unique carbonate substituted bioapatite of Champsocephalus gunnari icefish jaw and skull bones was carried out using NEXAFS spectroscopy. It has been established that these bones contain the B-type carbonate substituted hydroxyapatit with a content [CO3]2- anion of about 0.79-3.07 wt.%.

Linear dichroism in 3d transition metal NEXAFS of correlated materials [PDF]

, 2001
Investigations of 3d transition metal (TM) compounds by means of linear dichroism in TM K-NEXAFS will be reported. At this, the decomposition of the angular-dependent NEXAFS into orbital projected components are important problems.

Phase transition of BiNb1−xMnxO4−δ: Thermal analyse, NEXAFS, XPS and ESR-study

Reviews on Advanced Materials Science, 2019
The manganese-doped polymorphs of bismuth orthoniobate were studied using thermal analysis, ESR, XPS and NEXAFS spectroscopy. It was shown that the phase transition from the orthorhombic (α) to the triclinic (β) modification can be reversible and it can ...
