Diagrams showing Q[S(Q) − 1] for nano-CeO2 in (top) a cell fitted with perforated diamonds (Fig. 3) and (bottom) a standard diamond anvil cell. There is a dramatic decrease in the contribution to the overall scattering from diamonds in the perforated cell and this leads to a much better signal-to-noise discrimination at high Q, an important factor in deriving better resolved real-space correlation functions containing fewer `ripples' owing to Fourier termination errors. |
