Diffusion and growth of metal clusters in nanocomposites: a Kinetic Monte Carlo study
metal clusters, bulk and surface diffusion, agglomeration, Kinetic Monte Carlo
2011/9/2
Nobel metals that are deposited on a polymer surface exhibit surface diffusion and diffusion into the bulk. At the same time the metal atoms tend to form clusters because their cohesive energy is abou...
Nanocomposites Materials Generated from a Spray
Spray-pyrolysis Nano-powders Ferrihydrite Hematite Boehmite Alumina
2010/7/5
The Spray Pyrolysis (SP) process has been employed at moderate temperature (470-970 K) for the synthesis of micro- and nano-particles of hydrated metal oxides and of related nanocomposites. It has bee...
Gravitational and Magnetic separation in self-assembled clay-ferrofluid nanocomposites
SAXS Ferrofluids and laponite
2010/7/5
We report on experimental observations of self-assemblies in colloidal dispersions of clay nanoplatelets and magnetic nanoparticles. Visual observations have been combined with small angle X-ray scatt...
