Based on the atomic coordinates and species identified through steps (I)–(V), we examined every atom and manually adjusted 37 atoms, producing a 3D model of 23,196 atoms with 6,569 Fe and 16,627 ...

3D images of platinum particles between 2-3 nm in diameter shown rotating in liquid under an electron microscope. Each nanoparticle has approximately 600 atoms. White spheres indicate the position of ...
