Analytical transmission electron microscopy (TEM) is used to reveal sub-micrometer, internal
fine structure (the microstructure or ultrastructure) and chemistry in minerals. The amount …

When studying nominal magnetite nanoparticles, it is mandatory to obtain a precise
structural characterization to get an accurate relationship with their physiochemical …

We apply Fe K-edge extended X-ray absorption fine structure (EXAFS) spectroscopy and
pair distribution function (PDF) analysis of high-energy X-ray scattering to investigate the …

Siliceous ferrihydrites are abundant nanoparticles in natural environments. Although it is
well known that the physical properties of ferrihydrite are affected when formed in the …

This study investigates the effect of Fe3+ on the electronic structure of nanocrystalline ceria.
Systematic synchrotron X-ray absorption spectroscopy coupled with scanning transmission …

Total scattering experiments using synchrotron X-rays and spallation neutrons are providing
new insights into the structural characteristics of synthetic and natural ferrihydrite, a poorly …

Ferrihydrite (FHYD), a nanocrystalline material has long been described as a poorly
crystalline disordered mineral mainly due to its small crystal size which is typically 2− 6 𝑛𝑚 …
