What are the Challenges in Rietveld Refinement for Nanomaterials?
One of the main challenges in applying Rietveld refinement to nanomaterials is dealing with broad diffraction peaks, which arise from the small size of the nanoparticles. These broad peaks can make it difficult to distinguish between different phases and accurately determine lattice parameters. Additionally, nanomaterials often exhibit significant strain and defects, which complicate the refinement process. Advanced techniques and software are required to address these challenges and obtain reliable results.
