X-ray scattering and diffraction RSS feed

X-ray scattering and diffraction are techniques used to study the atomic and molecular structure of materials. X-rays are directed at a sample, and the resulting scattering patterns provide information about the arrangement and movement of atoms in the sample. X-ray diffraction specifically analyzes the interference patterns that result from X-rays interacting with repeating structures in a material, enabling scientists to determine the precise arrangement of atoms and gain insights into the material's properties.
