As a new material characterization technology, PDF (Pair Distribution Function) is useful in the study of the local structure of both crystal and amorphous materials.

The structural stability of SBA-15 is closely related to its pore size and properties, and XRD is one of the effective methods to characterize its structure.

The full name of XRD is X-ray diffraction, which uses the diffraction phenomenon of X-ray in the crystal to obtain the X-ray signal characteristics after diffraction, and gets the diffraction pattern after processing.

To determine whether there is asbestos in talc is usually a combination of polarizing or electron microscopy and X-ray diffraction, and the quantitative analysis of asbestos mainly uses X-ray diffraction method.

Small Angle X-ray scattering (SAXS) is a technology that collects scattered signals generated by X-rays passing through a sample to study the structural information of a sample in the range of 1~100 nm.

Most drugs exist in the form of crystals, using X-ray diffraction, we can obtain the diffraction information of drug characteristics for each different crystal type.

The Guiding Principle of Chiral Innovative drugs clearly stipulates that "the direct method for determination of molecular configuration of chiral drugs is single crystal X-ray structure analysis".

X-ray diffraction is an important means for people to understand and explore nature, especially in condensed matter physics, life medicine, history and many other fields play an active role.

Unlike powder XRD, which is widely used in the late stage of drug development and production, single crystal X-ray diffraction technology plays an important role in the early and middle stages of drug development.
