Combining Laue diffraction with Bragg coherent diffraction imaging at 34-ID-C

Anastasios Pateras, Ross Harder, Wonsuk Cha +10

Measurement modalities in Bragg coherent diffraction imaging (BCDI) rely on finding signal from a single nanoscale crystal object, which satisfies the Bragg condition among a large…

General approaches for shear-correcting coordinate transformations in Bragg coherent diffraction imaging: Part 2

Peng Li, Siddharth Maddali, Anastasios Pateras +4

X-ray Bragg coherent diffraction imaging has been demonstrated as a powerful three-dimensional (3D) microscopy approach for the investigation of sub-micrometer-scale crystalline pa…

General approaches for shear-correcting coordinate transformations in Bragg coherent diffraction imaging: Part 1

Siddharth Maddali, Peng Li, Anastasios Pateras +12

In this two-part article series we provide a generalized description of the scattering geometry of Bragg coherent diffraction imaging (BCDI) experiments, the shear distortion effec…

Studying Internal Compositions of Binary Alloy Pd-Rh Nanoparticles Using Bragg Coherent Diffraction Imaging

Tomoya Kawaguchi, Wonsuk Cha, Vitalii Latyshev +3

Bragg coherent diffraction imaging (BCDI), the well-established technique for imaging internal strain of nanoparticles, was used to image the internal compositional distribution of…

Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging

Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11

Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…

Nano-scale imaging of the full strain tensor of specific dislocations extracted from a bulk sample

Felix Hofmann, Nicholas W. Phillips, Suchandrima Das +5

Lattice defects play a key role in determining the properties of crystalline materials. Probing the 3D lattice strains that govern their interactions remains a challenge. Bragg Coh…
