Method of artificial intelligence algorithm to improve the automation level of Rietveld refinement
Computational materials science, 2019In this paper, artificial Intelligence (AI) algorithm is used in the Rietveld refinement process instead of the human decision. The program, PowderBot, is developed based on Fullprof engine, which proves the effectiveness of AI in Rietveld refinement. In

Structure analysis of graphite fluoride by the Rietveld method
Carbon, 1997Abstract The structure of the graphite fluoride prepared from mesocarbon microbeads (MCMBs) was analyzed by the Rietveld method based on the two types of space groups proposed previously (P6m2− and P3m1). The weighted pattern R-factor of the latter (25.28) was smaller than that of the former indicating that P3m1 is more valid.

Modelling the silica glass structure by the Rietveld method
Journal of Non-Crystalline Solids, 1995Abstract To refine amorphous structures like crystalline ones is impossible. This statement needs now some reconsideration in the case of silica glass. Starting with a microstrained crystalline model deriving from the α-carnegieite structure, atomic coordinates refinements by the Rietveld method prove to be possible.
