This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


Assuming the crystalline parameters in nanoparticles are the same as those in bulk crystals, an Au (gold) nanoparticle in diameter of ~2.3 nm contains 309 atoms. Those atoms can be packed into a completed polyhedron, such as icosahedrons, ino-decahedrons or cuboctahedrons. [1] In this type of clusters, approximately 50% atoms locate at the surface.
