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


The melting point of metal nanoparticles decreases dramatically with decrease of the nanoparticle size. For instance, the melting point of Ag (silver) nanoparticles is 1150 K at 20 nm in diameter and drops to 600 K at 4 nm [1]. Another example in Figure 2619 is given by the phase diagram of the structure of Au nanoparticles whose melting point decreases with decrease of the size of Au nanoparticles.
