NEXAFS Spectra Simulations of Nitrogen-Bearing Heterocycles
Five-membered heterocyclic compounds containing nitrogen atoms are important biomolecule building blocks. In addition to their fundamental biological importance, these molecular structures are used in several technological applications. Consequently, it is essential to develop techniques that allow the characterization of these fundamental systems.

NEXAFS study of carbonate substituted bioapatite
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.%.

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

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