When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

We compare diffraction patterns against the 2014 edition of the ICDD's Powder Diffraction File, a reference database of more than 340,000 reported crystalline phases to find the answer. We offer a ...

The X-ray Diffraction Facility (XDF) offers a full diffraction analysis service in materials science, structural chemistry, structural biology and solid state science. The facility is located in the ...
