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 has not taken full advantage of the relatively recent advances in synchrotron facilities. Here, synchrotron X-ray PDF analysis is compared...

Although pair distribution function (PDF) analysis by neutrons and X-ray scattering profile has been used to study materials, electron diffraction can offer advantages to characterize the atomic structure of clusters, amorphous samples, and nanomaterials. Electrons have higher scattering power than X-...
we report the glassy structure of 75Li2S-25P2S5immediately before the crystallization by using the differential pair distribution function (d-PDF) analysis of high-energy X-ray diffraction. Even though the ionic conductivity increases during the optimum annealing, the d-PDF analysis indicated that th...

Here, pair-distribution function (PDF) analysis of x-ray powder diffraction data demonstrate that the Cp*2Yb(4,4'-Me2-bipy) molecule is virtually unchanged through the valence transition. However, the molecule's stacking arrangement is altered through the valence transition. 展开 ...
Pair distribution function (PDF) analysis, based on experimental X-ray or neutron diffraction data of crystalline powders, provides an insight into structural disorder of complex materials. However, the observation of interatomic vectors is confined to their norms. Based on three-dimensional single ...
