High-angle scattering diffraction patterns of the second binary colloidal alloy sample, AB13. After the sample was melted, the scattering was fluidlike. Then Bragg peaks appeared about 7 days later. By following the growth of the Bragg peaks over time, researchers monitor the crystallization process. High-angle scattering is performed with a laser, a Bragg screen, and a high-angle camera.
