| Abstract Scope |
The kinetics of nanoparticle coalescence and growth has typically been modeled using the Ostwald ripening model. Interface energies are usually assumed to be constant throughout the process. However, determining the interface energy of nanoparticles as a function of changes in their chemical composition due to adsorption or segregation processes reveals the necessity to adjust the energy values in response to variations in surface excess during growth. Another often-overlooked effect during nanoparticle growth is the formation of solid-solid interfaces (grain boundaries). This work highlights the key considerations that should be taken into account during the coalescence and growth process concerning the energies of these interfaces. |
