Extended Data Fig. 10: Synchrotron XRD of the NDCs containing high-pressure neon.
From: Preservation of high-pressure volatiles in nanostructured diamond capsules
a, The XRD pattern of a recovered NDC sample containing high-pressure neon, which is the same sample as investigated by TEM in Extended Data Fig. 9. The raw XRD data (black circles) is fitted by Rietveld refinement (red curves) using a cubic diamond and fcc neon composite (b), or using a cubic diamond phase alone (c). The fit residuals are shown in blue curves. The x-ray wavelength was 0.3738 Å.
