Recently, the Ministry of Science and Technology announced the list of the second batch of key projects under the 2023 National key research and Development Plan "Basic scientific research Conditions and major scientific instruments and equipment research and development".

Different crystal forms of the same drug may differ significantly in appearance, solubility, melting point, etc., affecting the stability, production, bioavailability, and safety of the drug.

X-ray absorption spectroscopy is a spectral technique to analyze the elemental composition and electronic states of materials by using the signal changes before and after the incident of synchrotron radiation X-rays.

XAFS, as an advanced characterization technique for the local structure analysis of materials, can provide more accurate atomic structure coordination information in the short-range structure range than X-ray crystal diffraction.

A material whose properties are dominated by two-dimensional effects, the properties of the material on a two-dimensional scale are different from its properties on a larger scale.

According to the position and intensity changes of in-situ XRD diffraction peaks, the intermediates generated during the cycle can be inferred, and the reaction mechanism can be further derived from these intermediates.

X-ray Absorption Fine Structure(XAFS) is a powerful tool for studying the local atomic or electronic struct ure of materials based on synchrotron radiation light source.

In-situ XRD is one of the most popular and developed advanced characterization techniques for studying lithium-ion and sodium-ion battery systems in electrochemical processes.

It is difficult to quantify the amorphous and crystalline phases of cement materials due to the complexity of the mineral phases in the mixture and the significant overlapping peaks. Excellent results can be obtained by Rietveld refinement of the measured sample using standard measurement configurations.
