Main task of the project will be the application of non-destructive X-ray based high-resolution spectro-microscopic imaging methods and development of related data processing tools, with the aim to establish simple diffusion simulations by means of pore network modeling (PNM). Main microscopic methods will be synchrotron-based full-field transmission X-ray microscopy(FF-TXM) and X-ray fluorescence XRF tomography ; it will be tested whether these established tools can be supplemented by X-ray diffraction imaging, namely ptychography (scanning coherent diffraction imaging), and X-ray holotomography to achieve even higher 3D resolution, aiming to break the ‘meso-pore barrier’ of 50 nm.
