At the microXAS beamline, Dario Ferreira Sanchez's been responsible for the multimodal tomographic approach. That involves data analysis development, user support and collaboration, and in-line data reduction during and after the experiments as well.  The focus is on development to provide unique capabilities for Imaging Chemistry in Space and Time in an unlimited range of reactive systems at relevant spatial and temporal length scales. Hyperspectral Chemical Imaging allows a broad range of scientific communities to gain unrivaled insights into the chemical complexity of hierarchical, heterogeneous materials, including corresponding chemical reaction pathways and kinetics (reactivity).

    Main activities:

    • Development of synchrotron chemical imaging approaches: imaging chemistry in space and time.
    • Data analysis development.
    • Especial interest on energy related (engineered) materials, and technique analysis development.
      Research activities with especial focus on Solid Oxide Cells and Battery metamaterials.
    • Especial interest in advanced additive manufacturing.

    • Development of 3D full-field X-ray absorption spectroscopy computed tomography (FF-TomoXAS); 
    • User support at microXAS beamline. That includes: (i) proposal, experiment strategy development; (ii) experiment assistance; (iii) data processing and analysis; (iv) user 'coaching program' on data analysis, contribution to synchrotron schools; organization of workshops (and hands-on training); (v) post doctorate fellows, PhD and master students supervision; (vi) manuscript elaboration for publication.
    • Synchrotron instrumentation and experimental setup commissioning and development.

    Master´s in Physics . Universidade Federal do Paraná, UFPR, Brazil. Year of degree: 2009.

    Master degree obtained at the Department of Physics of UFPR (Brazil), supervised by Kleber Daum Machado, was focused on the investigation of the structural and optical properties of a class of amorphous alloy systems: chalcogenide glasses. Combined analysis of X-ray diffraction (XRD), EXAFS, Reverse Monte Carlo (RMC) method, and Raman spectroscopy was applied. RMC was applied using XRD data alone and XRD+EXAFS data simultaneously in order to investigate structural information such as mean interatomic distances and coordination numbers.

    Ph.D. in Physics . Universidade Federal do Rio Grande do Sul, UFRGS, Brazil. Year of degree: 2013. 

    Work of thesis (2009-2012) at the Physics Institute of UFRGS (Brazil), supervised by Paulo F. P. Fichtner and Pedro L. Grande, was focused on the microstructural, morphological and compositional characterization of nanostructured systems through the combination of several complementary techniques, which includes Medium Energy Ion Scattering (MEIS), Transmission Electron Microscopy (TEM), Grazing Incidence Small Angle X-Rays Scattering (GISAXS) and Rutherford Backscattering Spectrometry (RBS). The main focus of the thesis’ work was on the development and understanding of the MEIS technique applied in the modelling of buried nanostructured systems close to the surface.
