In the development of X-ray imaging technology, X-ray imaging technology has formed a relatively complete X-ray non-destructive testing technology system. In order to meet the needs, new detection technology is constantly innovated, and X-ray online detection technology is adopted.

At the European XFEL X-ray laser, the researchers used scandium to create a more accurate pulse generator with an accuracy of one second in 300 billion years, about a thousand times more accurate than today's standard atomic clocks based on cesium.

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. ​

The power conditions depend on the X-ray tube as the target material and focus type. Although Cu targets are widely used for diffraction, the use of Cu targets for residual austenite analysis is not recommended because of the strong fluorescence of iron-based materials.

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.

In the process of drug development, the properties and structure of drug crystal powders play a crucial role in their efficacy and safety, and the application of X-ray diffraction (XRD) technology provides us with a powerful tool.

X-ray diffractometer is a device that uses the principle of interaction between X-rays and substances to obtain information such as crystal structure and lattice constant of substances by measuring the diffraction Angle and intensity of X-rays in substances.

Three-dimensional covalent organic frameworks, due to their structured nanochannels, open pore environment and good stability, have gained more and more attention

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

Binder is a polymer compound used in electrode making to adhere the active substance to the collector fluid. The main function is to bond and maintain active substances.

In this paper, a series of hard carbon materials with adjustable structure were prepared using chitosan as carbon source, and the relationship between the evolution of hard carbon structure and the properties of sodium storage was analyzed.
