      abstract     = {Nanostructured tungstates, such as CoWO$_{4}$ and
                      CuWO$_{4}$, are very promising catalytic materials,
                      particularly for photocatalytic oxidation of water. The high
                      catalytic activity of tungstate nanoparticles partially is a
                      result of their extremely small sizes, and, consequently,
                      high surface-to-volume ratio. Therefore their properties
                      depend strongly on the atomic structure, which differ
                      significantly from that of the bulk material. X-ray
                      absorption spectroscopy is a powerful technique to address
                      the challenging problem of the local structure determination
                      in nanomaterials. In order to fully exploit the structural
                      information contained in X-ray absorption spectra, in this
                      study we employ a novel evolutionary algorithm (EA) for the
                      interpretation of the Co and Cu K-edges as well as the W
                      L$_{3}$-edge extended X-ray absorption fine structure
                      (EXAFS) of nanosized CoWO$_{4}$ and CuWO$_{4}$. The combined
                      EA-EXAFS approach and simultaneous analysis of the W L$_{3}$
                      and Co(Cu) K-edge EXAFS spectra allowed us for the first
                      time to obtain a 3D structure model of the tungstate
                      nanoparticles and to explore in details the effect of size,
                      temperature and transition metal type.},
