Short summary
X-ray absorption spectroscopy (XAS) was successfully used to investigate the atomic-scale environment of niobium (Nb) in ore minerals and Nb-doped compounds of technological importance. The demonstrated sensitivity of this technique to Nb minerals could help decipher Nb speciation in mining contexts such as hydrothermal and lateritic deposits and rationalize the origin of the enhanced physico-chemical properties of Nb-doped materials.
