Electrochemical ostwald ripening of colloidal ag particles on conductive substrates.
Thermally evaporated silver nanoparticles on conducting substrates spontaneously evolve in size when immersed in pure water. The process was studied using scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and optical absorption spectroscopy. The particles are proposed to reform through an electrochemical Ostwald ripening mechanism driven by the size dependence of the w...
متن کاملOstwald Ripening of -Carotene Nanoparticles
Ostwald ripening, the interfacial-energy-driven dissolution and reprecipitation of solutes, becomes an increasingly significant problem for nanoparticle formulations. We present the first quantitative study of Ostwald ripening for nanoparticle dispersions. The Lifshitz-Slyozov-Wagner (LSW) theory of particle growth driven by diffusion is applied to study -carotene nanoparticles with sizes of O ...
متن کاملHomoepitaxial Ostwald ripening
This paper reports level set simulations of the Ostwald ripening of two-dimensional homoepitaxial islands. The simulation accurately accounts for both adatom diffusion between the islands and adatom attachment/detachment processes at the island edges. We compute the time evolution of the average island size and the full island size distribution function. The results provide support for a previo...
