From: RETRACTED ARTICLE: Atomic insight into hydration shells around facetted nanoparticles
Comparison of hydration shells for 7 and 15 nm iron oxide nanoparticles (IONPs). Double difference PDFs (dd-PDFs) of 7 (blue) and 15 nm (red) sized IONP with two different ligands; citrate (solid line) and malic acid (dashed line). The similarity of the dd-PDFs shows that the nanoparticle size does not influence the structure of the hydration shell
