WPEM is a research project dedicated to resolving complex crystal structures and heavily overlapping Bragg peaks in mixed X-ray diffraction and polycrystalline powder diffraction data.

The project is led by Bin Cao and focuses on combining physics-based diffraction theory with modern AI techniques to improve the reliability and precision of structural characterization.

The WPEM framework enables several advanced diffraction analysis tasks:

• Detection of subtle structural differences
  (e.g., distinguishing α phase vs. α′ phase in Ti–Ni alloys)

• Separation of amorphous and crystalline components
  in complex polymer systems such as polybutene

• Analysis of complex solid-solution structures
  in multi-component materials

• Computation and interpretation of diffraction scattering information
  across the entire diffraction pattern

WPEM aims to build a high-precision computational framework for X-ray diffraction analysis, enabling more reliable structural identification in complex materials systems.

The project started in 2020 with a long-term goal of promoting open and reproducible scientific research in diffraction analysis.

We welcome collaborations in areas including:

• X-ray diffraction analysis
• crystal structure refinement
• AI-assisted materials characterization
