X-ray frequency and energy is second only to gamma rays, with penetration, frequency range 30PHz~300EHz, corresponding wavelength of 1pm~10nm, energy of 124eV~1.24MeV. Let's take a look at the properties and applications of X-rays.

This paper introduces the related knowledge of crystal pattern and crystal fetish

The X-ray intensity of nondestructive testing at a point in space is the sum of the number of photons and the energy product over a unit area perpendicular to the X-ray propagation direction in unit time.

Biological X-ray irradiator irradiates organisms with high-energy rays with ionizing radiation effect within a predetermined time, producing biological effects or suffering irreversible damage and destruction to achieve biological purposes.

In the field of NDT, there are mainly two detection methods: industrial CT detection and X-ray detection, both of which use X-rays to detect the interior of the object.

X-ray diffraction technique is widely used in drug analysis. X-ray diffraction technique is an analytical method used to study the structure of a substance. This technique has many applications in drug analysis.

The stronger the light, the brighter? But this is not always the case. When the intensity of the X-ray beam begins to exceed a certain critical value, the diffraction image unexpectedly weakens.

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of no sample destruction and simple operation.

SBA-15 is a mesoporous silicon-based molecular sieve with a highly ordered hexagonal straight pore structure (p6mm), the pore size can vary from 5 to 50 nm, and the pore wall is thicker.

The X-ray transmission inspection can provide a picture of whether there are defects in the inspection site of the casting and the relevant size, and the X-ray inspection system is widely used in industrial production.

In the past 10 years, the Institute of Physics of the Chinese Academy of Sciences has used powder diffraction method to determine the crystal structure of many inorganic and organic compounds.
