“…33 Gwaihir, a user-friendly and open-source Jupyter notebook graphical user interface, was used to process and analyze the Bragg coherent X-ray diffraction data. 34 The phase corresponds to the projection of the displacement field onto the scattering vector (here, Q 220 ). The retrieved phase is then processed to establish the maps of displacement and strain within the single NC using the BCDI python package.…”

High-energy Bragg coherent diffraction imaging (BCDI) can enable three-dimensional imaging of atomic structure within individual crystallites in complex environments. Here, we show that sufficient coherent photon flux is available to extend the BCDI technique to higher energies to (1) obtain improved strain information and sensitivity at the nanoscale with higher order Bragg reflections, (2) exploit BCDI in embedded materials or complex operando environments, (3) reduce X-ray induced sample modification, and (4) minimize dynamical scattering effects. We demonstrate the nanoscale imaging technique on the same submicrometer sized crystal at 8.5, 19.9, and 33.4 keV by taking advantage of the brilliance and coherence of the fourth generation Extremely Brilliant Source of the ID01 beamline at ESRF -The European Synchrotron (Grenoble, France). The photon flux, data quality, resolution and strain information are compared. We also show the first coherent diffraction measurements performed at the ID31-EBS beamline at an energy of 41 keV.

“…After the removal of the phase ramp and phase offset (calculated at the center of mass of the support), the data was finally interpolated onto an orthogonal grid for ease of visualization. Both the bcdi and cdiutils packages, as well as the Gwaihir GUI, were used for the later post-processing part.…”

Solid-state reactions play a key role in materials science. The evolution of the structure of a single 350 nm Ni 3 Fe nanoparticle, i.e., its morphology (facets) as well as its deformation field, has been followed by applying multireflection Bragg coherent diffraction imaging. Through this approach, we unveiled a demixing process that occurs at high temperatures (600 °C) under an Ar atmosphere. This process leads to the gradual emergence of a highly strained core−shell structure, distinguished by two distinct lattice parameters with a difference of 0.4%. Concurrently, this transformation causes the facets to vanish, ultimately yielding a rounded core−shell nanoparticle. This final structure comprises a Ni 3 Fe core surrounded by a 40 nm Ni-rich outer shell due to preferential iron oxidation. Providing in situ 3D imaging of the lattice parameters at the nanometer scale while varying the temperature, this study�with the support of atomistic simulations�not only showcases the power of in situ multireflection BCDI but also provides valuable insights into the mechanisms at work during a solid-state reaction characterized by a core−shell transition.
