The polycrystalline phenomenon of drugs refers to the formation of different crystal states of a compound molecule in the solid state due to the different crystal arrangement and filling methods. ​

Asbestos, also known as "asbestos", refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal erosion, electrical insulation and spinnability. The three most common types are chrysotile, iron and cyanite.

Sungkyunkwan University in South Korea has demonstrated that nano-Na5Ti3F14 / carbon nanocomposites have excellent electrochemical properties as the negative electrode of sodium-ion batteries.

Characterization methods of copper monatomic catalysts are often used to determine their structure and properties, and the following are several common characterization methods.

Cement is a common building supplies, generally divided into ordinary Portland cement, Portland cement mixed materials and special cement, the use of Portland cement is more.

Recently, Applied Clay Science reported "High-pressure Raman scattering and X-ray diffraction study of kaolinite, Al2Si2O5(OH)4."

Many materials through rolling, extrusion and other deformation processes, or even if not deformed, the grains in the polycrystal show more or less statistical uneven distribution, this organizational structure is called texture.

In recent years, with the demand for clean energy and the development of a net zero greenhouse gas emission economy, the field of electrocatalysis has attracted great interest.

The main indicators of polymer materials include the type of polymer or its crystallinity. Polymers also exhibit different microstructure, which can also affect the mechanical .properties of polymer materials.

X-ray diffraction (XRD) is a means of research to obtain information such as the composition of a material, the structure or form of an internal atom or molecule by analyzing its diffraction pattern through X-ray diffraction.
