The Au diffraction peaks (JCPDS: 04 0784) were caused by the diffraction from the catalyst.
Despite the revolutionary significance, the conventional far-field light microscopy is restricted by the diffraction limit based on the scale diffraction theory; that is, objects within a diffraction-limited spot, ∼250 nm, cannot be resolved.
It is worth mentioning that long-range structural properties, as determined by the diffraction experiment, such as neutron powder diffraction, can differ from those measured via spectroscopy, for example, NMR, which probes structure at shorter length scales.
The resolution is limited by the diffraction limit imposed by the fiber numerical aperture.
In optical microscopy, the spatial resolution is restricted by the diffraction limit of light.
This makes their crystals difficult to distinguish based on limited information provided by the diffraction data.
By analyzing the diffraction pattern using software, scientists can make a map of the electron density in the crystal.
Instead of reconstructing the crystal structure by inverting the diffraction data, virtual diffraction experiments are performed on the finite element mesh and the resulting simulated diffraction patterns are compared directly to the experimental results.
At each step, 2D slices of the diffraction pattern are acquired by the X-ray detector and subsequently collated to form a complete 3D diffraction pattern for reconstruction.
The particle size (PS) parameters were measured by the laser diffraction method in liquid mode.
The iron oxide chemical composition of SPIONs was verified by the XRD diffraction).
