New insights into the application of pair distribution function studies to biogenic and synthetic hydroxyapatites [PDF]

, 2020
Biogenic and synthetic hydroxyapatites are confounding materials whose properties remain uncertain, even after years of study. Pair distribution function (PDF) analysis was applied to hydroxyapatites in the 1970’s and 1980’s, but this area of research ...
