Supersaturation, nucleation, and phase separation are ubiquitous phenomena of great interest in both science industry. However, a unified, quantitative understanding these has yet to be achieved for mesoscopic materials. Here, we present set general equations that determine the monomer saturation degree, size distribution free energy materials, as well their transition conditions. These reveal that, under supersaturation, largest cluster (LCS) is an important state-variable; supersaturation...
In order to assess the potential of porous Si as thermoelectric material we have performed thermal conductivity measurements in dependence both temperature and average structure size. Investigations on samples with sizes between 7 nm 100 reveal a pronounced reduction which is encouraging for future use material. The observed size can be explained terms simple kinetic model based effective phonon mean free path.
Supersaturation and nucleus seed formation are universal processes that precede all phase transitions. Despite extensive research on nucleation, our understanding supersaturation, transition dynamics remains rudimentary. Here, we present exact statistical thermodynamic formula for the saturation degree, most-probable size distribution of mesoscopic nuclei, their transition, introducing state defined by temperature, total monomer concentration, largest cluster (LCS). These results show...

Citrate-stabilized palladium nanoparticles with a mean diameter of 13 nm were synthesized in aqueous solution. These particles utilized as catalysts to grow epitaxial silicon nanowires by chemical vapor deposition at temperatures below 500 °C. The resulting have 15 nm. It is found that during the growth process transform into dipalladium silicide.
