Abstract / Description:Unraveling the complex morphology of functional materials like core−shell nanoparticles and its evolution in different environments is still a challenge. Only recently has the single−particle coherent diffraction imaging (CDI), enabled by the ultrabright femtosecond free−electron laser pulses, provided breakthroughs in understanding mesoscopic morphology of nanoparticulate matter. Here, we report the first CDI results for Co@SiO2 core−shell nanoparticles randomly clustered in large airborne aggregates, obtained using the x−ray free−electron laser at the Linac Coherent Light Source. Our experimental results compare favourably with simulated diffraction patterns for clustered Co@SiO2 nanoparticles with ˜10 nm core diameter and ˜30 nm shell outer diameter, which confirms the ability to resolve the mesoscale morphology of complex metastable structures. The findings in this first morphological study of core−shell nanomaterials are a solid base for future time−resolved studies of dynamic phenomena in complex nanoparticulate matter using x−ray lasers
