Schematic Graphic (IMAGE) DOE/Brookhaven National Laboratory Caption A sketch of the new method that enables fast, 'on-the-fly' determination of three-dimensional structure of nanocatalysts. The neural network converts the x-ray absorption spectra into geometric information (such as nanoparticle sizes and shapes) and the structural models are obtained for each spectrum.
