Figure 1
2D coherent X-ray diffraction patterns before (a) and after oxidation (b) of three agglomerated Ni nanoparticles. The black boxed areas represent the gaps between the images sensors, dead pixels and the beam-stop area, and the data inside were not used in the reconstruction. (c, d) 2D projection CXDI image reconstructed using the diffraction amplitude shown in (a, b), respectively. The insets show the corresponding SEM images. |
