tlooto Summary
This framework enhances the interpretation of WAXD in heterogeneous fibre-based materials and can be embedded into advanced tomographic or machine-learning workflows, facilitating high-throughput structural characterization in scenarios where rotation is impractical or impossible.
Abstract
A generalized diffraction model is presented for anisotropic nanomaterials with fibre symmetry, enabling the extraction of 3D orientation, strain and angular dispersion from wide-angle X-ray scattering patterns without sample rotation. Validated on chitinous Bouligand structures in shrimp cuticle, this framework allows robust multi-reflection analysis and is broadly applicable to complex biological and synthetic fibre-based materials.
